摘要: A universal urethane die assembly for use in blanking, forming, drawing, embossing and the like. The assembly includes a urethane pressure pad which is rectangularly shaped with rounded corners. The retaining ring which surrounds and supports the pressure pad has unique dimensional requirements. Other features of the die assembly include a visual indicator for ascertaining the degree of deflection of the die assembly. Also included is a turret punch press which has a single urethane die assembly in lieu of an upper turret. A punching unit which includes a urethane die assembly in conjunction with a die button for use on presses and press brakes.
