Title: Chip-clogging preventive device of small diameter hole pressing die
Inventor: KOMATSU MAKOTO
IPC: B21D45/00
Filed: 2001-06-01
Abstract: PROBLEM TO BE SOLVED: To prevent chip-clogging of a die for stamping a minute diameter hole at a metal sheet. SOLUTION: The small diameter hole pressing die 1 provides a cutting edge 11 and a back relief hole 12 connecting to the rear of the cutting edge. A difference 13 in level spreading toward the back relief hole is arranged at a connecting portion between the rear end of the cutting edge and the front end of the back relief hole, and the back relief hole is made to have a hole diameter having no reverse slope toward the difference in level to the rear end. Thus, the unevenness of the length of the cutting edge is prevented by absorbing a shaft gap between the cutting edge and back relief hole in the difference in level, and the cutting edge can obtain a shape capable of preventing the occurrence of chip clogging.  Further, because the stamped chips loose a sliding support portion caused by the difference in level when pressed by the die, the drop of stamped chips becomes smooth in the back relief hole, and the probability of chip clogging is consequently reduced.
