Claims

[Scope of utility model registration request]

A drilling device for drilling a hole in a press work by lowering a punch facing a die, the punch holder supporting the punch via an elastic member so as to be movable in the vertical direction, on which the press work is placed. and a lower die provided with a die into which the punch is fitted supports the punch holder so as to be movable between a processing position and a retracted position, and an upper die is provided with an inclination that contacts the punch holder and advances the punch holder to the processing position. A driver cam is provided with a cam surface and a vertical cam surface that holds the punch holder in the processing position after being advanced, and the punch of the punch holder held in the processing position is held in the upper mold by the elastic force. A drilling device characterized by being provided with a pressing part that presses against a member and lowers the member.
