High speed punching apparatus - has device for selectively adjusting tool stripping force allowing work on different materials

摘要

The high speed punching apparatus is for cutting parts out of flat stock. The apparatus includes a device for selectively adjusting the tool stripping force to accommodate different materials and a device for avoiding possible cutting of an overlaying template. There is also a device for minimizing friction between the punching tool and associated die button and a device for minimizing hang up of burrs on the work piece in the die button and also a punching tool for minimizing friction and for expelling chips cut from the workpieace.
