| description | The invention provides a forming method of a rotor of a vacuum generator in an automobile engine. The forming method of the rotor of the vacuum generator in the automobile engine comprises the steps of firstly spheroidizing annealing, shot blasting and phosphorus saponifying a part blank obtained through hot rolling high-carbon steel, and then cold forging and forming. A die used by cold forging and forming is an assembled die, wherein an inner ring die of a main die is a prestress ring, and a main die core adopts a hard alloy; and a cold forging part is good in surface quality and high in size accuracy, and metal can be strengthened through cold forging, so that the strength of a part is improved, the service life of the cold-forged and formed rotor can be prolonged, the use strength of the rotor is improved, the rejection rate is reduced, and the material is saved.
本发明提供的汽车发动机内真空发生器转子成型方法，先对热轧高碳钢制成的零件毛坯进行球化退火、抛丸和磷皂化处理后，再进行冷锻成型。冷锻成型使用的模具为组合模具，其中主模的内圈模具为预应力圈，主模仁采用硬质合金，由于冷锻件表面质量好，尺寸精度高，冷锻能使金属强化，提高零件的强度，因此冷锻成型的 |
