High-speed blanking die with automatic detection function

The utility model discloses a high-speed blanking die with an automatic detection function, which comprises a lower die base plate, a lower die plate, a material pressing shaft, a punching hook punch A, a punching hook punch B, an upper die fixing plate, an upper die base plate, an upper die bottom plate, a lower die bottom plate, a base plate, a detection shaft A, a detection shaft B and a detection switch. The utility model relates to a commutator bar feeding device, which solves the problems that the commutator bar is different in length after being punched, forked tail pins are lost and the like to influence the performance of a commutator because a ladder bar cannot be normally sent to a corresponding punching position due to improper feeding or residues in a feeding groove of a die in the punching production process of the commutator bar. 本实用新型公开了一种具有自动检测功能的高速冲裁模具，包括下模垫板、下模板、压料轴、冲钩冲子A、冲钩冲子B、上模固板、上模垫板、上模底板、下模底板、底座板、检测轴A、检测轴B和检测开关，本实用新型的有益效果是：本实用结构简易，制作成本低，解决了换向片在冲裁生产过程中，因送料不到位，或是模具送料槽内残留东西，导致梯排不能正常送到相应冲裁
