Abstract：

In order to study the thermal deformation behavior and forging process of stainless steel material for brake lever bolt, a high temperature compression test for the material was carried out using a thermal simulator, obtaining the true stress-true strain curve and microstructures of this material. The data obtained from high temperature compression test were imported into a finite element simulation software Deform-3D to numerically simulate the forming process of brake lever bolt, and the load-stroke curve and the distribution of equivalent stress field in the forming process were analyzed. The corresponding die was designed according to optimized process parameters, and the subsequent process test was carried out. It shows that the brake lever bolt forgings are obtained by process test with full filling, required size and reasonable forging streamline distribution, and no forging defects are found after maching, which could meet the requirements of use. The research has certain guiding significance for the production of this kind of part.
