Chai Zhen,Su Changsheng,Wang Ronghui
Abstract:The structural characteristics and forming process of large body panel die are summarized. Aiming at the defects of traditional process, a cooling mechanism for high-speed deep punching forming die is developed, and the structural design of the cooling mechanism is introduced. The practice shows that the die structure is reasonable and the quality of high-speed deep punching meets the design requirements.
Key words:large body, forming process, cooling mechanism, high speed deep punching
