Description

Technical Field

[0001] The invention relates to the field of motor rotor core processing, and in particular to a forming device and a forming method for an air-conditioning motor rotor core. Background Art

[0002] The motor rotor is the rotating part in the motor. The motor rotor is divided into two types: inner rotor rotation mode and outer rotor rotation mode. The inner rotor rotation mode uses the core in the middle of the motor as the rotating body, outputting torque (referring to the motor) or inputting energy (referring to the generator); the outer rotor rotation mode uses the outer body of the motor as the rotating body. Different modes facilitate applications in various occasions. Among them, the core of the inner rotor made of iron core is the motor rotor iron core.

[0019] Step 2: Start the third hydraulic telescopic rod to drive the fixing part on the top of the rotating rod to rise, clamp the iron chip through the fixing part on the rotating rod, and drive the rotating rod to rotate through the fourth motor, so as to rotate the iron chip.

[0025] 3.
