Abstract
A bend-straightening machine with a vertically movable table for straightening long workpieces is provided. The bend-straightening machine of the present disclosure includes straightening supports for supporting a workpiece mounted on a movable table which moves in a vertical plane driven by a driving mechanism. The machine is constructed as a rigid frame including a base for supporting at least one upright column. A fixed bridge is joined to an upper portion of the upright column and supplies a stationary surface for mounting at least two workpiece holding fixtures, which grip the ends of the workpiece, allowing the workpiece to be rotated. Also, mounted to the bridge is at least one straightening punch which remains stationary during straightening. The moving table and straightening supports act vertically upward on the workpiece causing the workpiece to bend, i.e., straighten, when it contacts the straightening punch.
