摘　　要：从渗氮处理、TD覆层处理模具表面的工艺流程入手,对表面处理后的机械性能进行比较、将TD覆层处理的模具投入弯管工件进行成型加工,通过大量的生产实践验证了TD覆层处理是解决模具和工件拉伤问题的有效办法。This article compares the mechanical properties after the surface treatment and uses the TD Cladding mold to process the tube bending work based on nitriding and process flow that treats the mold surface by TD Cladding. It confirms TD Cladding is the effective method of solving stretching damage problems in the mass production process and obtains practical experience for increasing the tube bending mold serving life.
