Problems solved by technology

[0004] However, since the middle of the guide rail is subjected to concentrated load in this method, when the load reaches a certain level, it is easy to cause excessive local elastic-plastic deformation of the guide rail, so that the guide rail cannot be straightened, and the straightening effect is very poor

Abstract

The invention provides a guide rail straightening device which is used for straightening a guide rail and is characterized by comprising a supporting portion, four abutting portions, at least two pressure loading portions and control portion, wherein the supporting portion is used for supporting the guide rail; the four abutting portions are correspondingly arranged on the two sides of the guide rail in pairs; the at least two pressure loading portions are used for reversely bending the guide rail to straighten the guide rail; and the control portion comprises five guide rail side displacement sensors, two loading head side displacement sensors, a calculation part, a judgment part and a control part, wherein the five guide rail side displacement sensors are used for sensing distances between the five guide rail side displacement sensors and the guide rail, and the two loading head side displacement sensors are used for sensing the moving distance of loading heads; when the guide rail is placed on the supporting portion, the calculation part calculates an initial bending amount of the guide rail and a calculation distance required by the loading heads to straighten the guide rail based on the distance sensed by the guide rail side displacement sensors; and when the movement distance is equal to the calculation distance, a current bending amount of the guide rail is calculated, and the guide rail is straightened when the current bending amount is 0.

Description

technical field [0001] The invention relates to a straightening device, in particular to a guide rail straightening device capable of straightening a curved guide rail. Background technique [0002] As a typical metal profile, the guide rail is often bent and deformed due to external forces, temperature changes, and internal forces during various processing processes such as rolling, forging, extrusion, and transportation; moreover, due to the relatively large size of the guide rail, during processing A large amount of metal needs to be removed, which can easily cause the rail to bend and deform. Therefore, the bending deformation straightening process is an inevitable link to improve the straightness of the guide rail, and for high-precision guide rails, straightening is even more important. [0003] At present, reverse bending pressure straightening is a simple, flexible, economical and effective method for straightening guide rails. Usually, the commonly used method is ...
