Abstract
A punch guide/receptacle for a dambar-removal tool set has a mounting fixture and an insert adapted to mount to an adaptive region of the mounting fixture. Apertures for punch teeth in the guide/receptacle are a part of the insert. In practicing the invention inserts may be removed and repaired. In one embodiment the insert has an upper and a lower row of apertures, and repair may be accomplished in some instances simply by reversing the insert in the mounting block.
Claims8
An integrated punch guide/receptacle for a dambar-removal tool set having a punch with a plurality of teeth in a specific pattern, the guide/receptacle comprising:
- a mounting fixture adapted to mount to a frame of the tool set and having an insert-adaptive region;
- and
- an insert having an upper first aperture bar having a first row of apertures in the specific pattern of the punch teeth, and a lower second aperture bar having a second row of apertures also in the specific pattern of the punch teeth for receiving the punch teeth and material removed from dambars by the punch teeth, the insert adapted for mounting to the mounting fixture in the insert-adaptive region;
- wherein the insert mounts to the mounting fixture in the insert-adaptive region, the mounting fixture mounts to the tool set, and the insert may be reversed within the insert-adaptive region presenting the lower second bar of apertures in the position the upper first bar of apertures occupied before reversal.
