Abstract: A stamping tool includes a lower pad, upper pad, forming steel, and sub-pad. The lower pad includes a lower forming surface recessed in a first direction between a first lower pad surface and the second lower pad surface. The upper pad is movable along a second direction. In an extended position, the upper pad holds a workpiece against the first lower pad surface. The forming steel includes a first forming surface and is movable along the first direction. In an extended position, the forming steel is received in the recess. The sub-pad is coupled to the forming steel such that the forming steel moves the sub-pad in the first direction as the forming steel moves from the retracted position to an intermediate position in which the sub-pad holds the workpiece against the second lower pad surface while the forming steel continues to move to the extended position.
