球头销零件,材料多为普通碳素结构钢。传统的成形方法为机加工,它不但浪费大量的材料而且工件力学性能不理想。采用DEFORM-3D有限元软件对该球头销的成形过程进行了模拟,对不同直径不同长度的坯料进行了冷镦模拟实验,得出了较为合适的坯料尺寸。 Ball pin parts, materials and more common carbon structural steel. The traditional forming method for machining, it not only wasted a lot of material and mechanical properties of the workpiece is not satisfactory. The DEFORM-3D finite element software was used to simulate the forming process of the ball studs. The cold heading experiments on blanks with different diameters and different lengths were carried out, and the suitable blank size was obtained.
