Design of Drawing Compound Die for Side Hole Part

Based on the side hole and no flange and one-step drawing part forming analysis and comparison of the process, the compound die that can complete 4 procedures -blanking, drawing , punching and trimming at in the same forming-position was synchronously designed. Production testing confirmed that there were different levels of improvements in the product quality, production efficiency and economic efficiency. This paper describes die structure, die working process, design and manufacture of main pans of die.
