Anvil apparatus for a press

摘要

Conventional apparatus for pressing retaining rings into a track assembly do not properly line up with the retaining ring when the press is under the high pressure required. The subject apparatus overcomes this problem by providing a self-aligning anvil for driving a tool. The anvil has an adapter for mounting it to the press and an anvil member with a work surface for engaging the tool. The adapter engages the anvil member along a semi-spherical mating surface having a radius extending from the intersection of the centerline of the anvil and a plane extending through a tool land of the tool where it engages the workpiece. The anvil member is attached to the adapter by a pin attached to the anvil member which extends across the semi-spherical mating surface into a resilient member mounted in the adapter at its center.
