Production process of squirrel-cage motor rotor

The invention relates to a production process of a squirrel-cage motor rotor, which comprises the following steps of: disorganizing and stacking punched and formed silicon steel sheets to ensure that at least most of assembly holes forming an assembly groove are not punched by the same punch, further performing pressure casting to form an iron core, and performing shelling treatment on the iron core of which a conducting bar is subjected to pressure casting formation, so as to obtain the squirrel-cage motor rotor. According to the invention, the contact resistance between the conducting bars is increased, the rotor resistance is further increased, the minimum torque is improved, the resistance difference between different conducting bars of the rotor can be reduced, the torque fluctuation is inhibited, the starting torque of the motor is improved, and the problem of motor starting failure caused by a dead point appearing in a motor starting curve is solved. 本申请涉及一种鼠笼式电机转子的生产工艺，其通过对冲裁成型的硅钢片进行打乱码放以确保构成装配槽的装配孔至少
