H-shaped steel processing technology and preparation method thereof

Abstract

The invention belongs to the technical field of H-shaped steel processing and preparation, and particularly relates to an H-shaped steel processing technology and a preparation method thereof, and the H-shaped steel processing technology comprises seven steps of part blanking, H-shaped steel assembly, H-shaped steel welding, H-shaped steel correction, H-shaped steel end blanking, H-shaped steel drilling and H-shaped steel assembly. During welding, the hot air blower is adopted for continuous hot air blowing treatment in the advancing direction, steel scraps generated by carrying clamping and assembling clamping can be removed, meanwhile, heat treatment can be conducted on the steel scraps before welding, and therefore the welding quality can be improved, the strength of the H-shaped steel can be improved, and the service life of the H-shaped steel can be prolonged. In addition, the step of calibrating the assembled parts through the laser collimator is added between the H-shaped steel assembling step and the H-shaped steel welding step, bending of the parts during loading, transporting and assembling can be found in time, when bending occurs, treatment can be conducted firstly, then welding is conducted, and the straightness of the H-shaped steel is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of H-shaped steel processing and preparation, and particularly relates to an H-shaped steel processing technology and a preparation method thereof. Background technique [0002] 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. [0003] In the existing H-beam processing technology, before the welding process, the surface of the H-beam at the weld will generate steel chips due to handling and clamping, and the remaining steel chips are not removed during welding, which affects the quality of welding. , and the tem...

AI Technical Summary

Problems solved by technology

[0003] In the existing H-shaped steel processing technology, before the welding process, the surface of the H-shaped steel at the weld will produce steel scraps due to handling and clamping and assembly clamping. The remaining steel scraps are not removed during welding, which affects the quality of welding. , and the temperature at the edge is low during welding, resulting in low temperature during welding and poor healing effect after welding
