Embodiment 1

[0032] Embodiment 1: as Figure 1 to Figure 4 Shown is a method of manufacturing loose sheet motor iron cores by using the waste sheet self-fastening method. First, the steel plate is wound on the plate rolling machine, and the steel plate is uncoiled according to the width of the stator. After the steel plate is uncoiled, the surface or edge of the steel plate Unevenness occurs. Therefore, it is necessary to pass the steel plate uncoiled by the plate rolling machine through a precision leveling machine to level the surface of the steel plate. Pass the leveled steel plate into the automatic feeder, the automatic feeder sets the feeding speed according to the punching speed, automatically transports the steel plate, and transports the steel plate to the high-speed punching machine for punching.

[0033] When punching, first punch out the waste pieces in the tank, use a multi-station progressive die to punch out the waste pieces-1 in the loose piece tank body 3, and punch out th...

Embodiment 2

[0040] Embodiment 2: Other structures are the same as Embodiment 1, but for a part of the motor iron core, due to the need for setting, when the yoke portion 4 of the motor iron core is also provided with a through hole in the axial direction, like this, it can be The blanking position of waste sheet two 2 is arranged in the through hole in the yoke 4, like this, for the blanking in the tank body 3, can carry out once, other blanking and processing method are the same as embodiment 1, can equally Improve the quality of the product; for the stator loose pieces with a large surface area, 6 waste pieces 22 on the yoke 4 are arranged in axisymmetric arrangement, which can increase the mutual friction and improve the stator loose pieces. between fixed effects.

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...
