摘　　要：激光熔覆技术是一种新的表面改性技术,激光熔覆技术在汽车覆盖件模具上可以实现快速的修复工作,延长模具的使用寿命。其熔覆效果相比传统方法人工堆焊要均匀,很好控制厚度,通过摸索可以实现在表面质量要求很高的拉伸模凸模的修复工作。以激光熔覆技术在翼子板拉伸凸模修复上的实际应用为例,从激光熔覆技术和设备的介绍、工艺要求、参数设定和Dcam软件编程等几个方面,论述激光熔覆技术在汽车冲压模具修复上的应用和使用价值。As a new tecnology of surface modification,laser cladding can achieve the quick fixes of a die of automobil body panels and extend the die life.Because the cladding layer is easy to control,the cladding effect of laser cladding is more uniform than that of traditional maual overlaying.By optimizing the claddig process,the repair of the work area of drawig die with a high-quality surface can be achieved.This paper focused on the application of laser claddig on repairig the drawing die of fender.The investigation includes the review of technologies and machines of laser cladding,the process requirement,parameter setting and Dcam-programming.Moreover,the applied significance and the use-value of laser cladding were also introduced.
