Correction equipment for steel structure correction machining

Abstract

The invention discloses correction equipment for steel structure correction machining in the technical field of steel structure correction. The correction equipment comprises a correction box, a feeding port is formed in one end of the correction box, a discharging port is formed in the other end of the correction box, two first supporting plates are arranged in the correction box, and the two first supporting plates are arranged up and down; when the H-shaped steel needs to be corrected every time, the H-shaped steel is supported and positioned from the inner side of the H-shaped steel through cooperation of the supporting mechanism and the abutting mechanism, it is guaranteed that when the H-shaped steel is extruded and corrected after being heated and softened by the heating mechanism, an inner cross beam of the H-shaped steel is not bent, and the correction effect is improved; the H-shaped steel straightening device is simple in structure and convenient to use, deformation of the middle of the H-shaped steel in the straightening process is avoided, the H-shaped steel straightening device can adapt to straightening work of different types of H-shaped steel by means of the supporting mechanism and the abutting transverse moving distance set in advance, the applicability is wide, the H-shaped steel can be straightened in a segmented mode by being matched with a conveying mechanism, and the cost of straightening equipment is greatly saved.

Description

technical field [0001] The invention relates to the technical field of steel structure correction, in particular to a correction device for steel structure correction processing. Background technique [0002] H-beam is representative in processing steel structures. H-beam is an economical section and high-efficiency profile with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio. It is named because its cross section is the same as the English letter H. Since all parts of the H-beam are arranged at right angles, the H-beam has the advantages of strong bending resistance, simple construction, cost saving and light weight in all directions, and has been widely used. All parts of the H-beam are arranged at right angles, and the H-beam needs to be corrected during the manufacturing process. [0003] When correcting the H-shaped steel in the prior art, it is necessary to heat both sides of the H-shaped steel, and then perform extrusion ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a kind of straightening equipment for straightening and processing of steel structures, to solve the above-mentioned background technology. Extrusion correction is carried out, but since the hardness of the H-shaped steel decreases after heating, when the H-shaped steel is extruded by extrusion on both sides, the middle connecting beam of the H-shaped steel is easy to bend during the extrusion process, resulting in correction The effect is difficult to accurately grasp, the correction effect is poor, and there are differences in the size of the H-shaped steel. It is difficult to meet the correction needs of the same equipment for different models and different lengths of H-shaped steel in the existing technology.
