APPLICATION OF DRY LUBRICANT TO FORMING DIES AND FORMING DIES THAT OPERATE WITH HIGH FORCE

摘要

The present invention applies dry lubricant to appropriate components of a forming die (500) of a stamping press to minimize frictional force against such components during operation of the forming die (500) or to appropriate components of a forging die (700) of a forging press to minimize shear force against such components during operation of the forging die (700). A layer of dry lubricants (506, 514, 520, 526) is applied to any one or more of the die (502), the punch (510), or the binder (516, 522) of a forming die (500) of a stamping press, and a layer of hard chrome (504, 512, 518, 524) may also be plated thereon before the layer of dry lubricant is applied. A layer of dry lubricant (714) is applied on the inner surface of a cavity (706) within a forging die (700) of a forging press of the present invention. A dry lubricant may also be applied on the outer surface of the punch (702) of the forging press.
