In the modern urban lighting infrastructure and power communication tower manufacturing sector, lamp posts (including streetlight poles, traffic signal poles, and communication poles) often develop bending deformations during production and installation due to material rolling, transportation, or storage processes. These deformations compromise both aesthetic quality and structural load-bearing performance. Traditional rectification methods rely on manual straightening—workers manually apply corrective forces using jacks, crowbars, and hammering tools until straightening requirements are met. This approach not only suffers from low efficiency but also entails significant physical strain and safety risks. With advancements in mechanical manufacturing technology, lamp post straightening machines have been introduced as specialized equipment. Their core value lies not only in enhancing straightening accuracy and efficiency but also in systematically reducing manual labor intensity. To understand this improvement mechanism, it is essential to analyze three key aspects: the labor characteristics of manual straightening, the operational principles of straightening machines, and the evolving human-machine collaboration models.Cutting Equipment, Welding Equipment,Straightening Equipment,straightening machines.Advanced Automatic Light Pole Welding Machine  

 Even the most advanced equipment and manufacturing processes require proper maintenance and highly responsible operators to ensure optimal performance. Regular equipment maintenance is crucial for maintaining protective efficacy. Protective rubber sleeves or gaskets on fixtures are wear-prone components that must be periodically inspected for signs of wear or aging (e.g., cracking or hardening) and replaced promptly to maintain optimal elasticity. Proper cleaning and lubrication of moving parts such as equipment guides and lead screws are equally vital, as any jamming or vibration may cause unstable force application, potentially resulting in impact damage to coatings. The protective awareness of operators serves as both a fundamental and critical safeguard. Personnel must undergo systematic training to thoroughly understand the functions and vulnerabilities of various coatings, establishing a "zero-damage" operational objective. During operations, they should cultivate habits such as handling materials gently, maintaining clean contact surfaces, and conducting meticulous inspections. After each task, routine checks on lamp post coatings must be performed to confirm absence of new damage. Coating protection should be incorporated as a core evaluation criterion for straightening operation quality, with institutional measures reinforcing this philosophy. In summary, protecting surface coatings during lamp post straightening operations constitutes a comprehensive task spanning equipment design, manufacturing processes, technical implementation, and management practices. This requires integrating protective concepts from the initial design phase, enforcing meticulous operational protocols throughout workflows, adopting customized coating treatment strategies based on material properties, and leveraging intelligent sensor technology for precise adaptive control. All protective measures must be reinforced through systematic equipment maintenance and heightened personnel awareness. Only through such integrated approaches can we effectively restore lamp post structural integrity while safeguarding their protective "armor" against environmental degradation, thereby extending the service life of urban lighting infrastructure and achieving a win-win outcome of functional restoration and asset preservation.Cutting Equipment, Welding Equipment,Straightening Equipment,straightening machines.

With technological advancements, advanced straightening machines are elevating coating protection to new levels by integrating intelligent sensing and adaptive control systems. These technologies have achieved a leap from "empirical protection" to "perceptual protection." By integrating high-resolution visual sensors or laser scanners, the equipment can automatically identify and record the coating condition and geometric morphology of utility poles before operation. The system autonomously plans optimal gripping points and force application paths while proactively avoiding existing coating defects or structurally weak areas. During operation, real-time data from force sensors and displacement sensors form a closed-loop feedback system. The system not only controls force magnitude but also monitors for abnormal resistance fluctuations during application – which may indicate coating slippage or damage, prompting immediate action suspension or adjustment. Furthermore, by establishing a mechanical property database for various coating materials, the intelligent straightening system enables automatic matching of process parameters. Operators simply need to input the lamp post's coating type (e.g., "hot-dip galvanized-85μm" or "spray-coated polyester"), and the system automatically activates preset optimization parameters—including maximum allowable clamping force, progressive loading curves, and pressure holding duration—to ensure the workflow consistently operates within safe parameters for the coating. This material-specific adaptive control fundamentally reduces reliance on operator experience, achieving standardized and replicable coating protection.Cutting Equipment, Welding Equipment,Straightening Equipment,straightening machines.

The surface coatings of lamp posts are not uniform. Common types include hot-dip galvanizing layers, powder coating (spray painting), baked paint, and anodic oxide films on aluminum alloys. These materials exhibit varying properties such as hardness, elasticity, adhesion, and wear resistance, necessitating tailored protection strategies. For hot-dip galvanized lamp posts, their surface consists of a zinc metal layer with relatively low hardness, and the coating is metallurgically bonded to the steel substrate. The primary focus of protection lies in preventing scratches and zinc layer peeling. During straightening operations, in addition to using rubber-clad fixtures, special attention must be paid to temperature control throughout the process. Avoid generating excessive heat through localized intense friction, as elevated temperatures may compromise the microstructure of the galvanized layer. Although the sacrificial anode protection mechanism remains effective when the hot-dip galvanized layer is scratched by sharp objects, its visual appearance and localized protective performance will deteriorate. Therefore, direct contact with any sharp tools must be strictly prohibited during operations. For spray-painted lamp posts, their surfaces feature polymer coatings that exhibit excellent weather resistance and vibrant colors. However, these coatings may lack the hardness of metal plating layers, making them more susceptible to scratches, and plastic powder could soften under high temperatures. The primary task in protecting spray-painted coatings is to prevent scratches from hard objects and maintain surface smoothness. Protective pads at all contact points must be kept clean and free of impurities. Additionally, attention should be paid to whether force-induced substrate deformation may cause coating cracking. Spray-painted coatings have limited adaptability to substrate deformation (extensibility), and excessive bending corrections may lead to brittle cracking on the convex side. Therefore, correction should be performed at a slower pace, with immediate inspection after adjustment to check for whitening (stress whitening) or micro-crack formation in the coating. Aluminum alloy lamp posts and their anodized coatings exhibit high surface hardness but are relatively brittle, while the post material itself remains soft. The key to protection lies in preventing localized stress concentration. The clamping fixture's rubber coating layer requires increased thickness and enhanced elasticity to maximize contact area and ensure uniform pressure distribution. Extra caution is essential during straightening operations, as aluminum alloys have low yield strength and are prone to plastic deformation. Excessive substrate deformation may cause mesh-like cracks in the hard and brittle oxide coating. Therefore, equipment for aluminum alloy lamp post straightening must incorporate highly sensitive pressure feedback systems and precise displacement control mechanisms.Cutting Equipment, Welding Equipment,Straightening Equipment,straightening machines.

With appropriate equipment in place, standardized and meticulous operational procedures serve as a direct guarantee for coating protection. Operations must adhere to a systematic protective protocol. Preoperative inspection and preparation are critical. Operators must first thoroughly examine the surface coating condition of the lamp post to be straightened, confirming its type (e.g., hot-dip galvanizing, spray coating), thickness, and existing damage. For areas with localized coating damage or corrosion, documentation should be completed prior to straightening. When necessary, additional padding with soft protective materials (such as thick rubber sheets) may be applied to prevent aggravated damage during operation. The lamp post surface must be completely cleaned, particularly the clamping areas, ensuring no residual hard particles like sand particles or metal shavings. These microscopic particles can act as abrasive agents during straightening operations, causing severe scratches on the coating surface. The clamping and force application strategy during the process constitutes the critical component. First, precise adjustment of equipment fixtures must be performed to ensure their opening dimensions match the lamp post diameter, preventing unstable clamping caused by excessive clearance that leads to repeated friction, or over-tightening resulting in excessive initial pressure. Clamping positions should ideally be selected at the lamp post's reinforcing ribs or structurally supported internal areas, avoiding regions with thin coatings or decorative patterns. When applying corrective forces, the "progressive loading" principle must be followed to avoid sudden application of excessive impact forces. For lamp posts with significant bending, a multi-stage correction method with small incremental adjustments can be employed, allowing both material and coating to undergo gradual adaptation while minimizing instantaneous shear forces that may compromise coating adhesion. Throughout the force application process, operators must closely monitor the coating condition at contact points between lamp posts, fixtures, and pressure heads.Cutting Equipment, Welding Equipment,Straightening Equipment,straightening machines

In the maintenance and production of modern urban lighting facilities, lamp post straightening machines serve as critical equipment for repairing bending and twisting caused by transportation, installation, or external impacts. However, straightening operations inherently involve applying significant mechanical forces. Improper handling can easily result in scratches, indentations, or even peeling of anti-corrosion coatings on lamp post surfaces. These coatings—whether hot-dip galvanized layers, spray-painted coatings, or baked enamel layers—represent the lifeline ensuring long-term service and corrosion resistance in outdoor environments. Achieving dual objectives of precise deformation correction and optimal surface coating protection during straightening operations constitutes a systematic engineering challenge requiring integration of precision mechanical design, material science expertise, and standardized procedures. This article systematically outlines comprehensive protection strategies spanning equipment selection, process configuration, and operational implementation. Source Protection: Equipment Selection and Design Based on Coating Protection Requirements ：The first step in protective coating begins with selecting or using a straightening machine equipped with surface protection design capabilities. The mechanical structure of the equipment directly determines its interaction mode when contacting the lamp post. The core lies in the flexible and protective design of clamping and pressure application mechanisms. High-quality straightening machines employ specialized protective devices at direct contact points with lamp posts. For instance, roller shafts or V-blocks used to clamp lamp posts undergo rubber coating treatment, typically utilizing wear-resistant elastomeric materials like polyurethane with moderate hardness. This design not only provides sufficient friction to securely hold lamp posts and prevent slippage during force application, but also effectively cushions direct compression and abrasion from hard metal surfaces, preventing permanent dents or scratches. Similarly, pressure heads applied directly to bending points can be designed with flexible contact surfaces or equipped with replaceable protective pads to distribute pressure and safeguard coating integrity. Furthermore, the precision control capability of equipment is crucial for indirect coating protection. High-precision pressure and displacement control systems can prevent "overcompensation" during correction processes. Coarse pressure control may lead to excessive force application, causing localized deformation of lamp poles. Even without direct scratches, this could result in micro-cracks or reduced adhesion due to substrate plastic deformation. Therefore, selecting straightening machines equipped with high-precision pressure sensors and servo control systems enables stepless, precise adjustment of corrective forces. By dynamically modifying output based on real-time deformation feedback from lamp poles, these systems ensure effective curvature correction while maintaining force levels within safe parameters that prevent coating-substrate adhesion failure.

Overall, lamp post straightening machines effectively reduce manual shaping requirements and cost savings across multiple dimensions. By replacing labor-intensive, inefficient manual operations with mechanized automation, they directly lower workforce requirements and time costs. Precision control systems enhance quality consistency, minimizing rework and after-sales expenses. Improved operational safety mitigates workplace injuries and associated risks. Optimized workforce structure and training investments boost employment flexibility. Although initial expenditures for equipment procurement and maintenance may increase, these costs are offset by efficiency gains and quality improvements in scaled production operations, ultimately generating positive return on investment. The lamp post straightening machine does not merely replace manual labor, but rather restructures the cost structure of lamp post shaping processes through technological upgrades. By reducing manual shaping intensity, it enhances production efficiency, quality consistency, and safety standards, providing enterprises with a viable path to achieve cost reduction and efficiency improvement. Against the backdrop of continuous automation and intelligentization in manufacturing, the rational introduction of lamp post straightening machines combined with scientific production planning and maintenance management can deliver significant cost savings and competitive advantages in long-term operations.Cutting Equipment, Welding Equipment,Straightening Equipment,straightening machines

While pole straightening machines still require on-site personnel for operation and maintenance, the required workforce size and skill requirements have been significantly reduced. A single operator can manage one or multiple machines simultaneously, with training now focusing on equipment principles, software operation, and routine inspections—requiring less time than training skilled formers. This enables companies to flexibly allocate human resources, redirecting some labor to technical maintenance or higher-value positions to optimize labor costs. Furthermore, due to the high degree of equipment automation and reduced physical labor requirements, enterprises can alleviate recruitment difficulties and employment fluctuations to some extent, maintaining production continuity. This also serves as an implicit cost stabilization factor.  Cost-saving discussions must account for equipment procurement and maintenance expenses. While pole straightening machines require higher initial investments than traditional manual tools and necessitate regular maintenance, calibration, and potential spare parts replacement, their operational benefits in mass production scenarios—including enhanced efficiency, consistent quality, and reduced rework—can offset upfront costs within shorter timeframes, creating sustained cost advantages. The key lies in evaluating equipment utilization rates based on production scale and product specifications to ensure capacity-demand alignment, thereby preventing idle equipment from incurring additional costs.Cutting Equipment, Welding Equipment,Straightening Equipment,straightening machines

During manual lighting fixture installation, workers must perform pushing, pulling, striking, and positioning operations near large-scale lamp posts, posing risks of being struck by heavy objects, sustaining pinch injuries, or experiencing muscle strain. Particularly when handling high-strength steel components or extended lamp posts, improper force application may trigger accidental vibrations that endanger personal safety. Should safety incidents occur, they not only incur medical expenses and compensation costs but may also lead to production halts for rectification and increased insurance premiums, creating ripple effects across the supply chain. The pole straightening machine removes operators from high-risk direct force application processes. Operators primarily perform parameter settings and monitoring from control panels or within safe distances, significantly reducing physical contact and high-intensity labor. This enhanced safety effectively mitigates both explicit costs associated with work-related injuries and implicit reputational losses, achieving cost savings from a risk management perspective.

The quality of manual shaping largely depends on the operator's physical condition and skill level. Even experienced workers struggle to completely eliminate individual variations, often resulting in inconsistent straightness across products from the same batch. Such quality fluctuations may lead to assembly difficulties or require secondary shaping in subsequent processes, thereby increasing labor hours and material waste. The lamp post straightening machine utilizes closed-loop control and parameter stabilization to consistently produce lamps meeting precision requirements under identical conditions, significantly enhancing product consistency. Improved quality stability directly reduces rework rates and associated inspection costs, while minimizing customer complaints and after-sales resolution expenses caused by quality issues. In the long run, this preventive quality assurance approach proves more cost-effective than post-event remediation measures. Cutting Equipment, Welding Equipment,Straightening Equipment,straightening machines  

Efficiency serves as a critical metric for cost optimization. Manual straightening operations are constrained by human physical limitations and operational rhythms, typically requiring multiple cycles of measurement and adjustments per straightening process with inflexible timeframes. In contrast, pole straightening machines can continuously execute the workflow of clamping, pressurization, inspection, and release, significantly reducing single-operation duration. For mass production scenarios, stable production rhythm and high speed enable greater pole straightening capacity per unit time, thereby reducing fixed costs and shortening delivery cycles. Time cost savings are not only reflected in the production process but also extend to subsequent workflows. After plastic deformation, lamp posts can more quickly proceed to welding, painting, or assembly procedures, reducing work-in-process inventory and space occupation while enhancing overall production line efficiency. This chain reaction of speed improvement also holds significant implications for comprehensive manufacturing cost accounting.Cutting Equipment, Welding Equipment

Lamp post straightening machines typically employ a combination of mechanical clamping and multi-point force application principles. The power system drives the press head or rollers to apply controllable corrective forces on specific lamp post sections, while displacement and pressure sensors continuously monitor deformation recovery until preset straightness standards are met. This operational model transforms manual judgment and force application processes into programmed, repeatable mechanical actions, significantly reducing operator reliance on experience. Compared to manual reshaping, straightening machines demonstrate advantages in several critical aspects: Firstly, automated measurement and feedback systems minimize human reading errors and subjective judgment biases. Secondly, the controlled and uniform force application process prevents localized overloading or underloading, thereby reducing the probability of secondary reshaping. Thirdly, preset process parameters can be applied to lamp posts with varying diameters, wall thicknesses, and materials, enabling rapid switching and batch production consistency. This mechanized operation model directly reduces the required workforce and processing time for reshaping tasks. Cutting Equipment, Welding Equipment   Straightening Equipment,straightening machines

In traditional manufacturing processes, lamp pole straightening is typically performed by a team of skilled workers. Workers first visually inspect or use basic measuring tools to identify bending locations and severity, then apply localized force through hydraulic jacks, hand winches, and hammering tools to gradually restore the lamp pole to its designed straightness. This repetitive process of measurement, force application, and re-inspection requires significant time investment and demands both physical stamina and sustained concentration from the workers. From a cost perspective, manual plastic deformation involves both explicit and implicit costs. Explicit costs include direct labor expenses for personnel involved in operations, overtime fees, as well as wear and replacement of auxiliary tools. Implicit costs manifest through increased rework rates due to inconsistent plastic deformation precision, slower production cycles, prolonged equipment and facility utilization time, and potential occupational health risks from repetitive tasks. For batch production or large-scale lamp post processing, efficiency bottlenecks and quality fluctuations in manual plastic deformation can accumulate into substantial economic expenditures.

In modern metal processing and public infrastructure manufacturing sectors, lamp posts serve as common elongated components widely utilized in road lighting systems, traffic signage installations, and surveillance support structures. During production, transportation, or storage processes, lamp posts may experience deformation such as bending or twisting due to external forces or material stress, compromising their dimensional accuracy and operational performance. Traditional rectification methods rely on manual shaping techniques involving repeated adjustments using simple tooling equipment, which not only demands high labor intensity but also requires operators to possess specialized expertise. In recent years, lamp post straightening machines have become increasingly prevalent as specialized equipment designed to achieve precise alignment through mechanized automation. This study explores whether these machines can reduce manual shaping requirements and cost savings by examining operational mode transitions, efficiency improvements, quality stability enhancement, safety risk mitigation, and comprehensive cost structure analysis.

Different lamp post specifications (e.g., length, wall thickness, cross-sectional shape) impose varying requirements on straightening processes, necessitating high process adaptability in straightening machines. For instance, slender lamp posts with high aspect ratios are prone to deflection due to gravitational forces, requiring additional gravity compensation during straightening. Conical rods exhibit varying cross-sectional moments of inertia along their length, demanding dynamic adjustment of force application points according to cross-sectional changes. High-strength alloy rods demand precise force control to prevent brittle fracture. To enhance straight-line accuracy, continuous parameter optimization is required through process trials and data accumulation. This involves determining the number of force application points, force range, duration, and unloading rate for different materials and deviation types. By analyzing historical calibration data, a mapping relationship between deviation characteristics and process parameters is established, creating a reusable process database. Such ongoing parameter optimization enables the straightening machine to adapt to more complex operating conditions, maintaining straight-line accuracy at a consistently higher level.  Cutting Equipment, Welding Equipment,Straightening Equipment,straightening machines Conclusion: The leap from "correcting deviations" to "defining precision" in lamp post straightening machines represents a profound integration of material mechanics, inspection technology, and automated control systems. By employing precision detection as the "eyes" to identify deviations, controllable force application as the "hands" to reshape structural integrity, and internal stress regulation as the "anchor" to ensure stability, this technological advancement transforms streetlight poles from "qualified products" into "premium solutions." It simultaneously enhances overall lighting system performance, providing robust support for urban road safety and aesthetics. With continuous progress in inspection technologies and intelligent control algorithms, lamp post straightening machines are poised to achieve breakthroughs in precision, efficiency, and adaptability, emerging as indispensable precision manufacturing equipment in smart infrastructure development.

Even after applying force to eliminate visible bending deviations, residual stress distribution may still remain uneven within lamp posts. In certain areas, residual stress balances with external forces. When external conditions change (e.g., temperature fluctuations or prolonged loads), stress release can cause the pole to bend again—a phenomenon known as "rebound." Therefore, another key to improving straightening accuracy lies in controlling internal stress to ensure the pole maintains a stable straightened state post-correction. Cutting Equipment, Welding Equipment,Straightening Equipment,straightening machines Internal stress control in straightening machines is primarily achieved through two approaches: staged loading/unloading and aging treatment assistance. Staged loading involves applying incremental correction forces in phases to gradually expand plastic deformation within materials, preventing stress concentration caused by large one-time deformations. Staged unloading refers to systematically removing external forces after reaching target deformation levels, ensuring uniform distribution of residual stresses rather than localized accumulation. Some straightening machines integrate low-temperature aging or vibration aging functions, utilizing subtle temperature variations or mechanical vibrations to promote internal stress relaxation and further stabilize rod geometry. This dual control mechanism targeting both "explicit deviations" and "implicit stresses" ensures long-term linear accuracy stability, eliminating transient "correction artifacts."

The force application system of straightening machines serves as the core for precision calibration, requiring designs that meet the criteria of "multi-directional adjustability and precise controllability." Common force application methods include mechanical pressure (e.g., hydraulic cylinder pushing), mechanical tension (e.g., hydraulic drawing), or roller press straightening (e.g., alternating roll gap compression in multi-roll straightening machines). Some advanced equipment integrates hydraulic and mechanical composite force application to accommodate calibration needs for lamp posts with diverse cross-sections (circular, polygonal, conical) and materials (steel, aluminum alloy). The precision of force application manifests in three critical aspects: force magnitude control, force application point positioning, and force timing sequence. Force magnitude control requires threshold values determined by material mechanical properties. For low-carbon steel lamp posts, reversible correction during elastic deformation can be achieved with minimal force, while plastic deformation stages necessitate greater yet controllable force application to prevent cross-sectional distortion caused by excessive stress. Force application point positioning relies on high-precision guide rails and steering mechanisms to ensure precise alignment between force application points and detection system-identified misalignment areas, thereby avoiding new deviations from "misaligned force application." Force timing sequence refers to the sequential application of corrective forces across multiple points, typically adhering to the principle of "whole-to-part, primary bending before secondary bending." For instance, initial end-pulling eliminates overall lateral bending, followed by mid-section thrusting to correct localized protrusions, effectively preventing interference between corrective measures at different structural locations.Cutting Equipment, Welding Equipment,Straightening Equipment,straightening machines Furthermore, dynamic monitoring during force application is equally critical. Advanced straightening machines are equipped with real-time force feedback and deformation monitoring modules that continuously collect rod strain data throughout the process. When deviations between actual deformation and theoretical values are detected, force parameters are immediately fine-tuned to maintain controlled correction parameters. This "force application, real-time monitoring, and instant adjustment" dynamic control mechanism effectively prevents insufficient or excessive corrections caused by material inhomogeneities (such as strength variations between weld reinforcement zones and base materials).

To enhance straight-line accuracy, precise identification of pole deviation characteristics is essential, which relies on the detection system of the straightening machine. Traditional manual inspection methods, such as wire tensioning and ruler checks, are not only inefficient but also struggle to detect minor deviations and complex distortions. Modern pole straightening machines typically employ non-contact or contact multi-dimensional detection devices, including laser displacement sensors, electronic theodolites, or encoder-linked measurement mechanisms. These systems can collect cross-sectional center coordinates or busway straightness data at multiple points along the pole's length, thereby constructing a three-dimensional deviation model of the pole's axis.Cutting Equipment, Welding Equipment,Straightening Equipment,straightening machines The core value of the detection system lies in transforming "fuzzy curvature" into "quantifiable data." Through real-time data collection, it analyzes deviation types (e.g., unidirectional bending, S-shaped curvature, or helical distortion), locations (e.g., root, middle section, or tip), and magnitudes (e.g., large deviation values, slope variations). When transmitted to the control system, algorithms calculate theoretical force magnitudes, directions, and application sequences for each correction point based on material mechanical properties (e.g., elastic modulus, yield strength) and target straightness requirements. For instance, rod bending at the root requires concentrated application of counter-bending moments near the base, while mid-section bending necessitates symmetrical force distribution around the midpoint to achieve a "three-point bending" correction pattern. This closed-loop feedback mechanism of "detection-analysis-decision" shifts straightening processes from "trial-and-error experimentation" to "data-driven optimization," establishing an informational foundation for precision enhancement.

With the ongoing development of modern urban and transportation infrastructure, the demand for manufacturing and utilizing various types of lamp posts continues to grow. As a critical component ensuring the straightness, stability, and aesthetic appeal of lamp posts after installation, the selection of a lamp post straightening machine is particularly important. Faced with the diverse models and parameter configurations available in the market, how to scientifically select the appropriate machine based on specific application scenarios and the material properties of the lamp posts has become a core concern for many engineering firms and manufacturers. This article will elaborate on the working principles of lamp post straightening machines, key selection criteria, and the characteristics of compatible models for different materials, aiming to help readers establish a systematic understanding and provide practical references for procurement and application. 1. Basic Positioning and Operational Mechanism of Lamp Post Straightening Machines  A lamp post straightening machine is a device that corrects bent, deformed, or partially misaligned lamp posts through mechanical or hydraulic means. Its core function is to restore the geometric precision of lamp posts, ensuring they maintain vertical alignment after installation, thereby enhancing lighting coverage and safety performance. Structurally, such equipment typically consists of a frame, drive mechanism, pressure roller assembly, guiding device, and control system. During operation, the lamp post is fed into the straightening zone, where multiple pressure rollers apply controllable axial and radial forces to redistribute internal stresses and eliminate plastic deformation, achieving straightening correction. Understanding its working mechanism is fundamental to equipment selection: the straightening effect depends not only on the device's pressure output capability but also on the roller arrangement, feed rate control, and feedback adjustment precision. For lamp posts with varying diameters, wall thicknesses, and materials, the required pressure curve and straightening path differ, requiring the equipment to have adaptability and adjustability.Cutting Equipment, Welding Equipment,Straightening Equipment,straightening machines
