method and apparatus for forms of tunnel to horseshoe.

摘要

The method comprises the steps of cold pressing an indentation in the under surface of the shoe in an appropriate outer edge portion of the shoe to raise an appropriate volume of metal for the clip at the top surface and cold rolling the raised metal to form the clip. The preferred apparatus includes one or more hydraulic presses. In forming the indentation, a stationary punch is used and the horseshoe is clamped between a press head (35) and a resiliently depressable shoe support (12) and moved passed the punch. The preferred rolling press has an active roller and a reaction roller and the shoe is placed upon a bed having a platform sloping downwardly away from a die surface.
