Pipe straightening is a key post-production process in the manufacturing and processing of metal pipes, directly determining the straightness, roundness and overall accuracy of the pipes. It is a core link to ensure the subsequent assembly and usage performance of the pipes. After hot rolling, cold drawing and rolling, the pipes are generally subject to problems such as bending, twisting and ellipticity deviation due to factors like processing stress, equipment errors and material deformation. If they are not precisely straightened, it will directly affect the safety and compatibility of the pipes in fields such as oil and gas transportation, hydraulic equipment, aerospace and automotive manufacturing. As a dedicated core equipment for pipe precision calibration, the pipe straightening machine has, after years of technological iteration, upgraded from the traditional mechanical simple straightening to an intelligent high-precision fully automatic straightening device, fully meeting the quality requirements of high-end precision pipes.
Most traditional pipe straightening machines adopt a mechanical straightening mode with fixed roller spacing and fixed pressure. They have a simple structure and limited control accuracy, and can only complete basic pipe straightening operations. They have poor straightening effects on high-precision thin-walled pipes, special-shaped pipes, and alloy pipes, and are prone to problems such as uneven straightening, secondary deformation, and surface wear, making it difficult to meet the strict standards of high-end industries. The new generation of intelligent pipe straightening machine has completed a comprehensive innovation in the straightening structure and control system. It adopts a multi-roller symmetrical straightening structure and is equipped with a servo hydraulic precise pressure regulation system. It can dynamically adjust the straightening pressure, roller distance and running speed according to the material, diameter, wall thickness and deformation degree of the pipe, achieving flexible and precise straightening.
The core technical advantage of this equipment lies in its high-precision deformation detection and adaptive straightening control system. The equipment is equipped with a high-precision laser detection module, which can detect core parameters such as the straightness, ellipticity, and surface flatness of the pipe in real time throughout the process, accurately locate the deformation position and amplitude of the pipe, and automatically generate the optimal straightening plan through intelligent algorithms to complete targeted local precise straightening, completely solving the pain points of overall straightening and insufficient precision of traditional equipment. For different types of pipe defects such as bending, twisting and micro-deformation, the system can precisely distinguish and match the corresponding straightening process, effectively avoiding problems such as over-straightening, inadequate straightening and secondary damage.
In terms of product compatibility and production efficiency, the new type of pipe straightening machine has achieved full specification coverage. The equipment can be adapted to various material pipes such as carbon steel, stainless steel, alloy steel, copper-aluminum alloy, etc. It supports the straightening processing of different specifications of products such as small-diameter precision capillary tubes, conventional industrial pipes, and large-diameter thick-walled conveying pipes. At the same time, it can meet the straightening requirements of circular, elliptical and irregular-shaped pipes, and is suitable for production scenarios in multiple industries. The equipment adopts a continuous and automated operation mode and can be linked with upstream and downstream equipment such as cold drawing machines, plate rolling machines, and annealing furnaces to form an integrated pipe production line, achieving seamless connection from pipe forming, heat treatment to straightening, and significantly improving the overall production rhythm.
