The invention relates to a production method of an aluminum housing of a new energy automobile motor, which uses the following hardware devices: an outer shell mold device, an inner shell mold device, and an end cover mold device, and the end cover mold device is composed of a second upper template, an upper Mold base, upper mold core, lower mold core, lower mold base, second mold foot, second lower template, second slider, second locking block, second core-pulling oil cylinder, locking block oil cylinder, etc., and Through the production process of raw materials→feeding→forging and holding pressure→product forming, the aluminum shell of the motor, the aluminum inner shell of the motor, and the aluminum end cover of the motor are obtained. This production method can significantly improve the production efficiency of the motor aluminum shell, the yield rate of the good product can reach more than 95%, and the energy consumption of casting can be greatly reduced. No cracks, good mechanical properties and good stability.
Description
technical field [0001] The invention relates to the field of manufacturing new energy automobile motors, in particular to a method for manufacturing a new energy automobile motor housing. Background technique [0002] An electric vehicle refers to a vehicle powered by a vehicle-mounted power supply, driven by a motor to drive the wheels, and conforming to the requirements of road traffic and safety regulations. In recent years, pure electric vehicles as new energy vehicles have received strong support from national policies, and their development trend is getting better and better. At present, in order to make the drive motors used in electric vehicles or electric vehicles lighter in weight, faster in heat dissipation, and better in reliability, a large number of motor housings are cast with aluminum materials. However, compared with the shell casted by the original process, its shortcomings and limitations are also obvious, mainly reflected in: shrinkage porosity, shrinkag...
