Abstract
A punch press includes a die, a punch, a support that supports the punch, a shifting member, and a rotating mechanism. The shifting member includes an opposing surface that opposes the punch. The shifting member is movable toward and away from the die together with the support and the punch and rotatable about an axis extending in a direction in which the shifting member moves toward and away from the die. The shifting member includes a recess in the opposing surface. The rotating mechanism rotates the shifting member about the axis to shift the shifting member between an abutment position where the basal end surface of the punch is abut against the opposing surface and a retraction position where the basal end surface of the punch is retracted into the recess.
Claims5
A punch press comprising:
- a die on which a work is mounted;
- a punch opposing the die;
- a support that supports the punch to be movable toward and away from the die;
- a shifting member including an opposing surface that opposes a basal end surface of the punch, wherein the shifting member is configured to be movable toward and away from the die together with the support and the punch and rotatable about an axis extending in a direction in which the shifting member moves toward and away from the die, wherein the shifting member includes a recess in the opposing surface into which the basal end surface of the punch is retracted;
- and
- a rotating mechanism that rotates the shifting member about the axis to shift the shifting member between an abutment position where the basal end surface of the punch is abut against the opposing surface and a retraction position where the basal end surface of the punch is retracted into the recess.
