Abstract

A hand-held power performs three operations, selectively. A first operation corrects the setting of an improperly set self-piercing rivet. A second operation removes a self-piercing rivet from workpieces. A third operation sets a solid rivet, which may replace a removed self-piercing rivet. For performing these operations, three interchangeable sets of components are provided.

Claims

1. An apparatus for use in correcting the setting of self-piercing rivets improperly set in workpieces, for use in removing self-piercing rivets from workpieces, and for use in setting solid rivets in workpieces, comprising:

a frame having a pair of arms with portions spaced apart to provide a gap for receiving workpieces between opposed positions of the arms;

a die support at one of said positions and a punch support at the other of said positions, the punch support being reciprocative with respect to the die support; and

three interchangeable sets of punch-and-die components, each set having components constructed for detachable mounting on said die support and on said punch support, respectively,

wherein a first of said sets of components is constructed to correct the setting of an improperly set self-piercing rivet, a second of said sets of said components is constructed to remove a set self-piercing rivet, and a third of said sets of components is constructed to set a solid rivet.

2. Apparatus according to claim 1, wherein each of the first and third sets of components includes a punch constructed to fit in a hole in the punch support, a base constructed to fit in a hole in the die support, and a die constructed to fit in a hole in the base, and wherein the second set of components includes a punch constructed to fit in the hole in the punch support and a die constructed to fit in the hole in the die support, and having a passage through which a self-piercing rivet can be expelled by the punch.

3. Apparatus according to claim 2, wherein the dies of the first and third sets are detachable from the corresponding bases.

4. Apparatus according to claim 1, wherein the frame is a C-frame having said arms.

5. Apparatus according to claim 4, wherein the apparatus is a hand-held power tool having a body supporting the C-frame and a motor for moving the punch support, and having a handle attached to the body and a trigger on the handle for operating the motor.
