摘　　要：为了提高缝纫机的长梭芯套壳的生产效率,提高产品品质并节约原料,根据冷挤压成形原理,结合零件本身的特点,设计出合理的冷挤压成形工艺以及模具结构。通过数值模拟的方法仿真了其成形过程,结果显示,成形品质良好,工件尺寸达标,填充完整,符合预期。In order to improve the production efficiency of the spindle core shell in sewing machine and improve the quality of the products and save a large amount of raw materials, according to the principle of cold extrusion forming, combined with the part＇s design features, a reasonable cold extrusion forming process and die structure was designed and the forming process was numerically simulated. The results show that the better forming quality can be obtained with standard size and whole filling.
