Problems solved by technology

The winding slots must be neat, which is beneficial to the subsequent off-line, and has a greater impact on the magnetic field distribution. Therefore, during the lamination process, the winding slots on each punch need to be in one-to-one correspondence, and the rotor core is in interference with the rotor shaft. After mating, the tension force of the rotor shaft on the rotor core is mainly concentrated in the middle of the iron co

Abstract

The invention relates to the technical field of rotor iron core production, and discloses a rotor iron core stacking die which comprises an iron core punching sheet positioning seat, a rotor shaft pressing seat and an iron core punching sheet pressing seat. The rotor shaft pressing seat and the iron core punching sheet pressing seat are located above the iron core punching sheet positioning seat. According to the invention, the laminated rotor iron core punching sheets are circumferentially positioned through the iron core punching sheet positioning seat, the positions of the winding grooves of the rotor iron core punching sheets are ensured to be in one-to-one correspondence, the subsequent off-line operation is facilitated, and the rotor shaft pressing seat and the iron core punching sheet pressing seat axially press the rotor shaft and the rotor iron core punching sheets respectively, so that the rotor iron core punching sheets are tightly connected with the rotor shaft, all layers of rotor iron core punching sheets are tightly attached, it is guaranteed that the size of the stacked rotor iron core is matched with the set size, and meanwhile after stacking, the surface of each rotor iron core punching sheet is smooth, the stacking process is simple, the efficiency is high, the size precision is high, and the quality is good.

Description

technical field [0001] The invention relates to the technical field of rotor core production, in particular to a rotor core stacking die. Background technique [0002] In the motor industry, the rotor core is one of the important parts of the motor. It is mainly composed of stacked core punches and rotor shafts, and then cooperates with the winding through the rotor core to form a regular flow when the current exists. Magnetic field, so as to realize the special function of the motor. The stacking quality of the rotor core greatly affects the performance of the motor. [0003] Multiple winding slots are processed on the outer circumference of the stacked iron core punches, and the enameled wire windings are embedded in the winding slots to achieve specific functions. Due to the existence of winding slots, many problems have been brought about in the stacked production of rotor cores. The winding slots must be neat, which is beneficial to the subsequent off-line, and has a...
