摘　　要：通过分析农机链条外链板工艺特点,提出了冲压工艺改进方法,将条料手工送进改为自动送料,将敞开式压力机、单工序模冲压改为多工位级进模、大吨位闭式高速压力机冲压,极大地提高了生产效率和产品质量,节约了成本。An analysis was made on the process characteristics of external chain plate technology and an improvement on the stamping technique was proposed. In the new process, automatic strip-delivery, a large tonnage of high-speed press machine and a multi-position progressive die are applied that greatly increase the production efficiency and quality and lower the costs at the same time.
