Abstract

The invention provides an automatic stacking device and production method for stator-rotor iron cores, relating to the technical field of motor stator and rotor punching equipment. The automatic stacking device for the stator-rotor iron cores comprises a blanking male die, a blanking female die and glue spraying nozzles connected with a glue conveying pipe; a plurality of through holes are distributed on the blanking male die, the glue spraying nozzles are respectively inserted and fixed in the through holes, the glue spraying nozzles directly face stator punching sheets / rotor punching sheetspositioned on the blanking female die, the glue spraying nozzles can spray glue liquid on the upper surfaces of the stator punching sheets / the rotor punching sheets before the blanking male die presses the stator punching sheets / the rotor punching sheets positioned on the blanking female die, and the stator punching sheets / the rotor punching sheets can be adhered and fixed with the adjacent statorpunching sheets / the rotor punching sheets through the pressing of the blanking male die. Thereby, the technical problems that the stator-rotor iron cores formed by riveting in the prior art have lowstacking coefficients, low riveting force and easy damages to the insulating layer between the sheets, and the performance of the motor is affected can be alleviated.

Description

technical field [0001] The invention relates to the technical field of stamping equipment for motor stator and rotor, in particular to an automatic stacking device and production method for stator and rotor iron cores. Background technique [0002] The stator and rotor of the motor are the key parts of the motor. They are made of silicon steel sheets with good magnetic conductivity, which are stacked one by one after radial stamping and blanking. The stacking of stator and rotor punching sheets is also a key process in the manufacture of stator and rotor. Most of the manufacturing processes use: ordinary punching press punching, manual weighing, sheet sorting, stator rivet riveting or buckle buckle, rotor rivet riveting or pressing shaft , low work efficiency, low quality. Such as figure 1 As shown, after the emergence of high-speed punching machines, most of them use the buckle riveting process. It is a fully automatic and efficient production process that realizes in th...
