摘要
In accordance with the requirement of manufacturing dies quickly and economically,a hybrid forming method of stamping dies for automobile panels is proposed.The method combines digital patternless casting and high-power laser cladding.An experimental study is conducted on the hybrid forming process and its trial production and application in the manufacturing of stamping dies for typical panels.Results prove that the laser cladding layer exceeds HRC60(Rockwell hardness)and thus meets the production efficiency requirement of automobile dies.The rate of defects is well controlled.Compared with traditional technology,this technology has remarkable advantages and advancement.
