Spinning roller die

The utility model provides a spinning roller mold. The spinning roller mold comprises a rotating body which is integrally in a frustum shape, the rotating body is made of 45 steel with the Rockwell hardness of 31-35. The angle part of the big end of the frustum of the rotating body is an annular arc-shaped spinning working surface; a metal coating with the Rockwell hardness of 58-62 is deposited on the surface of the spinning working face. The main body part of the spinning die is made of 45 steel with lower hardness, so that the toughness of the spinning die can be effectively improved, the vibration during working of the spinning die is reduced, the metal coating with higher hardness is only deposited on the spinning working surface of the corner part of the large head part of the spinning die, the hardness of the working part is improved, and the service life of the spinning die is prolonged. Therefore, the spinning die has hardness and shock absorption capacity, the service life of the spinning die is pro
