[0002] The motor rotor is the rotating part of the motor. It forms a complete motor together with the motor stator. At present, the production steps of the motor rotor include stamping, aluminum casting, pressing, turning, and milling. A punching machine is required for stamping, but the existing punching machine The safety is not high. During the stamping process, workers are often accidentally injured by the punch press, especially for unskilled workers. Aluminum melting furnaces are needed when casting aluminum. The existing aluminum melting furnaces use scoops when casting The molten aluminum is scooped out with a spoon, but this method is labor-intensive for workers, and it is difficult to accurately control the amount of molten aluminum, resulting in the quality of cast aluminum not meeting the requirements. During the process of melting aluminum, the internal pressure of the aluminum melting furnace continues to increase. If the air pressure balance is not adjusted in time, it may cause the aluminum melting furnace to expand and explode. The existing method is to open a pressure relief port on the aluminum melting furnace. This method can release the pressure in time, but it is easy to be mixed with outside air, which will affect the purity of the aluminum liquid. , After melting aluminum, it is necessary to heat and keep the unused molten aluminum, otherwise the hot gas will keep rising, causing the molten aluminum at the bottom of the melting furnace to solidify. The existing aluminum melting furnace uses heating of molten aluminum to achieve heat preservation. This does ensure the state of the molten aluminum, but it greatly increases energy consumption. A hydraulic press is required for finalizing the shaft. The existing hydraulic press can only process one part at a time. The production efficiency is low, and the hydraulic press will produce strong vibration when working. , the existing hydraulic press has poor shock absorption effect, high risk factor in use, and a lathe is needed for turning. The lathe generates a lot of heat when processing the workpiece, and the lathe itself dissipates heat slowly, which causes the lathe to work for a period of time. It needs to stop for heat dissipation, which reduces the overall production efficiency. After stamping, the motor rotor will generate high heat due to instantaneous deformation. At present, workers remove the motor rotor with bare hands, which has the risk of scalding, and the motor rotor has to wait for the temperature of the motor rotor to drop before proceeding. In the next step of processing, at the same time, the surface of the motor rotor after stamping is not smooth, and there is a risk of scratching the worker's hands when grasping, so it is necessary to make improvements
