Three-dimensional modeling software Pro / EngineerWildfire was used to model the three-dimensional cylindrical helical gears and their forming molds. The three-dimensional thermal coupled finite element numerical simulation technique was used to simulate the temperature and precision forming process of the cylindrical helical gears using the finite element numerical simulation software Deform-3D Dimensional rigid-viscoplastic finite element numerical simulation. The distribution of temperature field in gear during warm precision forming process is analyzed. The law of temperature field distribution of gear is obtained. It provides an effective method for the application of warm precision forming technology of cylindrical helical gear in industrial production reference.
