Application of dry lubricant to forming dies and forging dies that operate with high force

摘要

The present invention applies dry lubricant to appropriate components of a forming die of a stamping press to minimize frictional force against such components during operation of the forming die or to appropriate components of a forging die of a forging press to minimize shear force against such components during operation of the forging die. A layer of dry lubricant is applied to any one or more of the die, the punch, or the binder of a forming die of a stamping press, and a layer of hard chrome may also be plated thereon before the layer of dry lubricant is applied. A layer of dry lubricant is applied on the inner surface of a cavity within a forging die of a forging press of the present invention. A dry lubricant may also be applied on the outer surface of the punch of the forging press.
