Production process for adapter with internal and external dodecagonal plum-blossom-shaped teeth and application of production process

The invention relates to the field of machining, and discloses a production process for an adapter with internal and external dodecagonal plum-blossom-shaped teeth and application of the production process. The production process comprises the following steps of step 1, cutting a blank; step 2, cutting a front end surface of the blank and shaping; step 3, cutting a back end surface of the blank and shaping again; step 4, preforming the external dodecagonal plum-blossom-shaped teeth; step 5, integrally forming the external dodecagonal plum-blossom-shaped teeth; step 6, turning and finishing excess materials; and step 7, broaching and forming the internal plum-blossom-shaped teeth. The defects that a traditional processing method is low in material utilization rate, the size is difficult tomeet the assembly requirement and precision for fast disassembly, the production efficiency is low, the capacity cannot meet the market requirements and the like are changed, the characteristics of cold heading and cold extru
