Description

Technical Field

[0002] With the continuous improvement of the requirements for material strength and lightweight in the industrial manufacturing, building structure, and automotive industries, high-strength steel is increasingly used in the manufacturing of various key load-bearing components due to its excellent mechanical properties and good formability. Most of the existing methods for preparing high-strength steel rely on complex heat treatment processes and control of material alloy composition. Although they can meet the strength index requirements to a certain extent, there are problems such as cumbersome preparation processes, high energy consumption, low processing efficiency, and poor product size consistency.

[0003] In the existing production lines, high-strength steel is often processed by single-station forming or segmented pressing. There are phenomena such as jamming and offset during the transmission of the steel, resulting in low processing accuracy. At the same time, there are often defects of stress concentration and unevenness on the surface of the steel after pressing, which affect its final use performance and the effect of subsequent coating treatment. In addition, most of the existing equipment lacks a coordinated mechanism for synchronous guiding and forming during continuous processing, which easily leads to asynchronous processing of multiple steel raw materials, thus affecting the production line efficiency.

[0004] Therefore, there is an urgent need for a method for preparing high-strength steel with a reasonable structure that can achieve automatic guiding, multi-group pressing, and continuous forming of steel, so as to solve the problems of low processing efficiency, poor forming consistency, and unstable surface quality in the existing technology, and meet the actual needs of modern manufacturing for high-performance steel products.
