Abstract
The invention discloses a regeneration method for a worn male/female die of an automobile part stamping die. The regeneration method comprises the following steps: a) forming a rear-earth Zn-Al alloy plating at the worn part of the male/female die by a hot-dipping process; b) melting a filling material by heating, and spreading the filling material at the worn part of the male/female die; and c) machining the regenerated part at the worn part of the male/female die flat and smooth. According to the regeneration method, a transition layer is formed by the hot-dipping process and contributes to improving the bonding property of a die surface and the filling material; and the optimal filling material has a favorable bonding property on the premise of meeting high mechanical hardness, so that the regenerated male/female die has better firmness and strength to achieve the effect of regenerating the worn male/female die. The regeneration method greatly saves the manufacturing and repair costs of the stamping die and shortens the processing cycle of the stamping die, improves the reliability of the regenerated male/female die and provides a new idea and a new method for the conventional process.
