Номер: CN116603937A
Автор: CHEN SHITAO, WANG HAILING, RUAN LINFAN, DING WENJUN, XU XIAO, GAO SHUANGMING
Принадлежит:

The invention discloses a long and short shaft floor common die stamping die which comprises an upper die base and a lower die base, an upper switching insert assembly, a short shaft fixing upper trimming insert, a long shaft fixing upper trimming insert and a common material pressing core are installed on the upper die base, and a long shaft flexible material pressing core is arranged between the short shaft fixing upper trimming insert and the long shaft fixing upper trimming insert. The shared material pressing core is fixedly arranged on one side, where the upper trimming insert is fixed, of the short shaft; a lower switching insert assembly, a long shaft fixing lower trimming insert and a short shaft fixing lower trimming insert are installed on the lower die base. Stamping forming of long-axis floors and short-axis floors of different sizes can be achieved through one set of die, the number of dies is effectively reduced, and the tool development cost is reduced.
