摘要： A punch press includes: a press main body; an upper turret member having a workpiece detecting plate; a lower turret member; a striker; striker ascending/descending means; a carriage with a clamper for holding a workpiece in order to position the workpiece between the upper turret member and the lower turret member; and carriage moving means to move the carriage in the horizontal direction. In the above construction, one end of a first conductive wire is electrically connected to the workpiece detecting plate; and one end of a second conductive wire is electrically connected to the press main body. The other end of the first conductive wire and the other end of the second conductive wire are electrically connected to a touch detecting unit to detect a touch between the workpiece detecting plate of the upper turret member and a workpiece clamped by the clamper.

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.
