Forming process analysis and drawing die design of different cone end cover
CAO Xing-yu (Kailong High Technology Co., Ltd., Wuxi, Jiangsu 214000, China)
Abstract: The structure features and manufacturability of the different cone end cover were analyzed, and the conventional processing route was introduced. Through the relevant theoretical calculation, the drawing process was optimised from the aspects of shortening delivery cycle and reducing die costs, and 2 drawing dies were used to complete the end cover forming, and the structure and working process were introduced.
Key words: different cone end cover; forming process; die structure; drawing coefficient
