Problems solved by technology

[0004] Aiming at the problems existing in the prior art, the embodiment of the present invention provides a motor core processing method, which is used to solve the processing problem caused by the stacking of multiple silicon steel sheets when the motor core is processed by the wire electric discharge cutting method in the prior art. The electrical conductivity of the parts is poor, which leads to the technical problem that the motor core cannot be processed normally and the processing efficiency is reduced.

Embodiment 1

[0035] This embodiment provides a method for processing the iron core of a motor, such as figure 1 As shown, the methods include:

[0036] S110, after immersing each silicon steel sheet in the glue solution, take it out and let it dry for a preset time;

[0037] In this step, before immersing each silicon steel sheet in the glue solution, the glue solution needs to be prepared according to a preset ratio. Here is to use alcohol and glue to prepare glue solution, the ratio of alcohol to glue is 1:3~1:5.

[0038] Then immerse each silicon steel sheet in the glue solution, so that both sides of the silicon steel sheet are evenly coated with glue to improve the bonding effect; and reduce the thickness of the glue film as much as possible to increase the lamination coefficient of the silicon steel sheet. Then take it out and let it dry for a preset time; the preset time is generally 5-8 minutes, preferably 6 minutes.

[0058] In practical application, the motor iron core is processed using the processing method provided in Embodiment 1, and the specific implementation is as follows:

[0059] Use alcohol and glue to prepare glue solution, the ratio of alcohol to glue is 1:3. Then immerse each silicon steel sheet in the glue solution, so that both sides of the silicon steel sheet are evenly coated with glue to improve the bonding effect; and reduce the thickness of the glue film as much as possible to increase the lamination coefficient of the silicon steel sheet. Then take it out and let it dry for the preset time; the preset time is 5 minutes.

[0060] Stack multiple silicon steel sheets with glue on their surfaces, and press the multiple stacked silicon steel sheets according to the preset lamination coefficient to form silicon steel laminations. The specific implementation is as follows:

[0061] Determine the corresponding hydraulic cylinder strokes in each pressing process based on form...

Abstract

The invention provides a motor iron core processing method which comprises the following steps: immersing each silicon steel sheet in a glue aqueous solution and then taking out and airing until a preset time; pressing a plurality of stacked silicon steel sheets according to a preset lamination coefficient to form a silicon steel laminate; wrapping the periphery of the silicon steel laminate by aconductive metal foil after polishing the periphery of the pressed silicon steel laminate; machining positioning holes in the upper surface of the silicon steel laminate; taking the positioning holesas the cutting reference and processing the silicon steel laminate into a motor iron core by an electric spark cutting machine after polishing the upper and lower surfaces of the silicon steel laminate; using the conductive metal foil to wrap a plurality of silicon steel so that the mutually insulated silicon steel sheets can be mutually conducted and the conductivity of the silicon steel laminateworkpiece is increased; and polishing the upper and lower surfaces of the silicon steel laminate to remove the insulating coating on the silicon steel surface before cutting so as to further increasethe electrical conductivity, ensure that the silicon steel laminate workpiece has good electrical conductivity and further improve the processing efficiency.

Description

technical field [0001] The invention belongs to the technical field of motor processing, and in particular relates to a method for processing a motor iron core. Background technique [0002] At present, most motors use silicon steel material as the magnetic core. When developing new motor products or small batch trial production of motor products, wire EDM is usually used to process the motor core. [0003] Since wire electric discharge machining uses positive and negative electrode discharges to generate electric sparks, the instantaneous high temperature of electric sparks melts the local metal of the workpiece, thereby realizing wire cutting processing. This kind of wire electric discharge cutting principle determines that the processed workpiece must have good conductivity, otherwise the wire will be broken frequently due to poor discharge during the processing process, which will seriously affect the processing process. The surface of the silicon steel material used to...
