Manufacturing process of motor rotor iron core with special-shaped tooth part

Abstract

The invention discloses a manufacturing process of a motor rotor iron core with a special-shaped tooth part. A material belt sequentially passes through a guide hole and mark hole blanking station, a ventilation hole blanking station, a first appearance hole blanking station, a second appearance hole and shaft hole blanking station, a buckling point blanking station, a small through hole blanking station and a blanking rotating station to continuously form a plurality of iron core pieces, and the iron core pieces do not coincide after being rotated, and are mutually in fixed connection to form a rotor core; the iron core sheets can be rotated under the condition that the two adjacent iron core sheets do not coincide, so that the two adjacent iron core sheets in the iron core obtained through automatic production do not coincide, and automatic production can be effectively carried out to obtain the iron core with the two adjacent iron core sheets not coincide and the special-shaped tooth part; moreover, the forming is reliable, and the efficiency is high.

Description

technical field [0001] The invention relates to the technical field of a motor core manufacturing process for new energy vehicles, in particular to a motor rotor core manufacturing process with special-shaped teeth. Background technique [0002] At present, new energy vehicles are vigorously promoted and further popularized, especially electric vehicles, and the motor core is the heart of the new energy vehicle drive motor, and its manufacture has always attracted people's attention. At present, for the motor rotor core with teeth, each piece needs to be rotated during the forming and stacking process of the iron chips, so that the two adjacent iron chips do not overlap. However, the existing technology cannot realize that the two adjacent iron chips do not overlap. Under normal circumstances, it rotates, so that the motor rotor core cannot be manufactured. Based on the above, the inventor finally has the manufacturing process of the present invention in view of research and...

AI Technical Summary

Problems solved by technology

At present, for the motor rotor core with teeth, each piece needs to be rotated during the forming and stacking process of the iron sheets, so that the two adjacent iron sheets do not overlap. However, the existing technology cannot realize that the two adjacent iron sheets do not overlap. Under the condition of rotation, the motor rotor core cannot be manufactured. Based on the above, the inventor finally has the manufacturing process of the present invention in view of the research and improvement.
