Problems solved by technology

The stator is usually used as a non-rotating part, and the rotor is usually embedded in the inner position of the stator. The traditional iron core is made by stamping, and the left side is extruded into one body. The requirements for the iron sheet are very high during extrusion. , usually there should be no burrs. The traditional punching method is to punch the hole and then deburr it.

Abstract

The invention belongs to the field of motor manufacturing, particularly relates to a punching method of a motor iron core, and particularly relates to a punching device of a motor stator in the punching process of the motor stator in the punching method of the motor iron core. The punching device of the motor iron core comprises a T-shaped supporting frame, a top beam is fixedly arranged at the cylinder end of the supporting frame, a punching mechanism is arranged on the top beam, a dust suction mechanism for adsorbing burrs is arranged in the punching mechanism, a rotating mechanism is arranged on a base of the supporting frame, a grinding belt rotates to grind punched holes and grind the burrs generated in the punching process, a piston shaft is reset after punching, and in the process, the grinding belt can correct deformed holes. By using the method and the device, the problem of burr grinding during punching can be effectively solved, and deformation of iron sheets during burr grinding can be prevented.

Description

technical field [0001] The invention belongs to the field of motor manufacturing, and in particular relates to a punching method of a motor iron core. Background technique [0002] The iron core (magnetic core) plays a pivotal role in the entire motor. It is used to increase the magnetic flux of the inductance coil and realize the maximum conversion of electromagnetic power. The motor core is usually composed of a stator and a rotor. The stator is usually used as a non-rotating part, and the rotor is usually embedded in the inner position of the stator. The traditional iron core is made by stamping, and the left side is extruded into one body. The requirements for the iron sheet are very high during extrusion. , Usually there should be no burrs. The traditional punching method is to punch the hole and then deburr it. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned problems in the prior art, and propose a method for p...
