Procedure for applying a lubricant transfer to the surface of a forge and a forge with a lubricant transfer device.

摘要

A method for forming a lubricant coat on a surface of steel slug (7) to be forged and a forging device (1) provided with a lubricant coat forming system (20). The method makes possible the forging of hard to work material, such as stainless steel. Highly durable parts can be manufacured easily. The durability of the metal molds (11-14) of the forging device (1) is increased, thereby decreasing the cost for the manufacture of the parts. In the method, the uniformly thick lubricant coat can be formed easily even on the transformed end surfaces of the material (7) being worked, providing effective lubrication. The lubricant coat forming member (20) can replace the oil lubrication of the related-art forging device of the inline type, in which the cut end surfaces of the material are not lubricated, without modifying the structure of the related-art forging device especially. The forging device (1) of this invention continously forges the material (7), lengthening the interval for replacing metal molds (11-14) and decreasing the cost for the manufacture of the parts.
