中文摘要：对击针成形工艺进行了分析,采用冷镦挤工艺制备该零件，并进行了工艺计算，介绍了剪切模和冷镦挤模的结构，给出了冷镦挤凹模的设计方法，保证了该零件冷镦挤成形的进行。
英文摘要：The molding process of the firing pin was analyzed, the part was formed by cold upsetting-extruding process, and the process design was calculated. The shear modulus and microstructure of the cold upsetting-extruding mode were introduced. The cold upsetting and extrusion die design method was given, which can ascertain the cold upsetting-extruding
