Firstly, this paper analyzes the development status of processed flange at home and abroad, and makes clear the significance of flange design.?Then the flange parts are analyzed, the structure and material properties are described and the processing technology of the flange drilling die is determined.?Then the processing route of the flange drilling die is designed, and the processing precision of the flange drilling die is analyzed.?Finally, three-dimensional modeling design and two-dimensional drawing modeling of flange drill die are analyzed. This study hopes to contribute
