AI Technical Summary

Technical Problem

Residual stress generated during the manufacturing process of metal supports can lead to permanent shape changes, microcracks, and shortened fatigue life in structural components. In particular, stress concentration at welded joints can cause fractures.

Method used

A metal bracket with a residual stress release guiding structure is designed. By setting a release groove and a buffer sleeve inside the mounting plate, the stress is evenly distributed by the support column and screw system, and the stress is guided through the release port and release point. Combined with a mesh reinforcement plate, the structural stability is improved.

Benefits of technology

It effectively prevents stress concentration, avoids material damage and deformation, extends the service life of structural components, improves the safety and reliability of the structure, and simplifies the installation process.

Abstract

The utility model relates to the technical field of metal supports, in particular to a metal support with a residual stress release guide structure, which comprises two mounting plates which are symmetrically arranged, a supporting mechanism is arranged between the two mounting plates, the supporting mechanism comprises a release groove and a supporting column, and the release groove and the supporting column are symmetrically arranged. The release grooves are formed in the mounting plates, positioning grooves are formed between the release grooves and one ends of the mounting plates, the two ends of the supporting column abut against the positioning grooves of the two mounting plates, a fastening groove is formed in the supporting column, and fixing grooves are formed in the two sides of the two ends of the fastening groove. When the structure is subjected to an external load, stress can be uniformly distributed in the whole structure through the release grooves, the stress concentration phenomenon possibly occurring in the traditional design is avoided, and the release openings in the two ends of the supporting column effectively guide and release residual stress.
