Crimping tool

INTRODUCTION
This document describes functionality of the tool, design data, design units and complete manufacturing drawings.

MAIN SECTION
The crimping tool is mounted directly to hydraulic piston or a vertical drilling machine opposite to an external collet where the idler or roller is placed.
The crimping tool has four jaws mounted on its moving part which moves inside the tool body. The jaws are actuated by the cam, the conical end of the tool body. When the crimping tool is rest four compression springs force the moving part out from the tool body. The four jaws are spread by four small compression springs mounted between the moving tool and each jaw.
When the tool is lowered on the top of the roller assembly (after placing the thin metal) the centering tool is aligning them. Continued lowering causes contact between the moving tool and the roller assembly, after that the tool body forces through the cam, the four jaws to spread, which crimps the thin metal part around the roller assembly. The limit pin controls the movement of the moving tool in order not to fall down from the crimping tool.
