摘要： In order to obtain uniform pressing force applied to a workpiece by an ironing die and easily disengage the workpiece after completing plastic working for the workpiece, a forming machine for performing the plastic working for the workpiece has a base pedestal, a forming punch provided on the base pedestal, and an annular ironing die arranged over the forming punch. The forming punch comprises a main punch body, six punch collets to be engaged with the main punch body and separated from each other at equal angles, a metal sleeve externally fitted to the main punch body and the punch collets, and a holder for holding the metal sleeve.

摘要： A hydraulic pressure control apparatus comprises a high pressure accumulator for sucking pressure oil supplied to a relief chamber of a relief valve to make changeover for the relief valve from a valve-closed state to a valve-open state when a forming load is applied to the pressure oil charged in a pressure chamber and the hydraulic pressure of the pressure oil arrives at a relief preset pressure, and a low pressure accumulator for sucking the pressure oil charged in the pressure chamber via the relief valve which is in the valve-open state.
