Method for manufacturing bulk sheet motor iron core by using waste sheet self-buckling mode

Abstract

The invention discloses a method for manufacturing a bulk sheet motor iron core by using a waste sheet self-buckling mode, and belongs to the technical field of motor manufacturing. The bulk sheets ofthe stator are connected together as a whole by setting the buckling point process of the waste sheets in the punching groove, the waste sheet self-buckling process in the punching groove and the reverse pressure self-buckling process and the like so as to facilitate processing. The production efficiency can be improved by changing the manual arrangement process of the bulk sheets of the stator so that the deformation phenomenon of the bulk sheets of the stator in the processing course can be prevented, the flatness of the bulk sheets of the stator can be maintained, the product accuracy canbe ensured, the iron loss can be controlled, the magnetic permeability of the material can be improved and the overall performance of the motor can be improved.

Description

technical field [0001] The invention belongs to the technical field of motor manufacturing, and in particular relates to a motor core manufacturing method in which waste pieces are self-fastened and stacked together for overall processing in the process of manufacturing loose pieces of motor iron cores. method. Background technique [0002] The motor core is the core component of the motor. It consists of a stator and a rotor. The stator is a fixed and non-rotating structure. The rotor is embedded inside the stator. The function of the motor core is to increase the magnetic flux of the inductance coil and realize the maximum conversion of electromagnetic power. [0003] The traditional motor core processing method is to first use a mold to punch into loose pieces through a punching process, and the loose pieces are processed by various methods, and then need to be manually sorted by workers. In this way, on the one hand, the production efficiency is low and the labor intensi...

Problems solved by technology

However, due to the above method, part of the waste sheet punched out of the groove is discharged, the part is left in the die, and the part of the waste sheet left in the die is pressed back into the sheet body, so sometimes when there is When there is an error, when the waste sheet cannot be pressed into the sheet body, it will affect the production process and affect the continuity of processing

[0006] There are also some methods. In order to avoid solder joints in the iron core, or to prevent the waste pieces of the iron core from being pressed into the sheet during processing, the self-fastening point is set on the yoke, which also affects the surface of the loose pieces of the motor iron core. The flatness affects the quality of the product
