Abstract
The structure design, work principle, equipment tonnage selection and process parameter calculation of the trimming- punching compound die for track link with pitch of 190 mm were introduced in this paper. The objective of the die was to complete the two procedures of trimming and punching in the each working stroke of the crank press. With the use of the ejection device, which includes draw bar, U-shape plate, mold plate and ejector, the forging blank could be separated from punch and die timely after trimming and punching. Proved in practice, the die design is reasonable, and the die can satisfy the requirement of forging quality and mass produce, besides, the operation is convenient, reliable and safe. The die reduces the labor intensity, cost and working process, and the production efficiency and the utilization ratio of the equipment are increased by 2 times.关键词
