Steel member with integrated thickness cross-section gradient performance control and method of manufacture and use

Abstract

The application discloses a kind of integrated thickness cross section gradient performance control steel member and manufacturing method and application, belong to automobile, mechanical parts manufacturing technical field;Solved the technical problems that current technology needs to be carried out by hot pressing forming, welding or laser sintering etc. when preparing gradient performance control steel member, its manufacturing process is complex and time-consuming, cost is high.This application realizes the same steel plate performance gradient control, and can be used for the manufacture of performance gradient parts required by automobile crash beam etc.The manufacturing method of the application comprises the following steps: step 1, cutting the steel plate according to the unfolded size of the part;Step 2, cold work the steel plate into a camber surface by bending deformation or roll bending deformation, respectively generating tensile and compressive stress mode;Step 3, finish machining the steel plate according to the size requirement of the part, complete the part manufacturing.The application can prepare integrated thickness cross section gradient performance control steel parts without the complex process of steel plate hot stamping, welding and laser sintering etc.
