The utility model discloses a spinning die favorable for eliminating cracks, which comprises a flat plate, a die body is arranged at the top end of the flat plate, two annular grooves are formed in the surface of the flat plate in a penetrating manner, sliding blocks are connected to the inner walls of the two annular grooves in a sliding manner, grooves are formed in the top ends of the two sliding blocks, and a plurality of auxiliary rotating wheels are arranged in the two grooves. The outer walls of the multiple auxiliary rotating wheels are fixedly connected with heat conduction pieces, a motor is arranged in the middle of the bottom end of the flat plate, and the output end of the motor is fixedly sleeved with a fixing ring. Furthermore, an auxiliary rotating wheel can be driven to roll under the running fit of a movable shaft, so that a heat-conducting fin is driven to be in contact with the bottom end of the die body for rolling extrusion, the spinning workpiece is more attached to the die under the au
