Hardened metal workpiece straightening machine

摘要

An apparatus and method for straightening the curvature of a hardened metal workpiece. A relatively sharp chisel point peen is driven by an air hammer to repeatedly strike the surface of the workpiece held on a rigid support table until the workpiece is straightened. The force or frequency of the peen chisel strikes can be infinitely varied by controlling the amount of air pressure delivered to the air hammer. Measurement of the workpiece is accomplished on the worktable by extending the workpiece between a pair of V-blocks and beneath a plurality of dial indicators.
