Embodiment 1

[0049] A production process for punching electric motors, characterized in that the sheet punching includes the following steps:

[0050] S1: unfold the sheet and coil to obtain the sheet;

[0051] S2: Transport the sheet to the punching machine, and before the sheet enters the punching press, attach a layer of liquid film on the upper and lower surfaces of the sheet, the liquid film is formed by punching liquid, and the punching liquid includes the following raw materials and their quality Number of copies:

[0052] 100 parts of solvent,

[0053] 20-30 parts of film-forming agent,

[0054] The solvent is water; the film-forming agent is dihydrogen phosphate and the phosphate of dihydrogen phosphate is insoluble in the solvent;

[0055] S3: Punching the plate, punching to obtain the initial sheet material of the stator and rotor, and punching the outer contour of the stator punching prefabricated part 1 on the initial sheet material of the stator and rotor;

[0056] S4: Pu...

Embodiment 2

[0068] A production process for punching a motor. On the basis of Example 1B, a flow aid is added to the raw material of the punching liquid, and the flow aid is graphene or a graphene derivative. The raw materials of blanking fluid are assisted in mixing under ultrasonic vibration, so that the flow aid can be dispersed evenly. The ingredients and dosage of the glidant are as follows.

[0069] According to the above-mentioned process, embodiment 2A-2I is set, flow aid and consumption are as follows.

[0070]

[0071] The self-flowing pavement test and the incision surface insulation resistivity detection of the punched prefabricated parts were carried out on the obtained blanking fluid.

[0072] Self-flowing pavement test: Select a flat plate with the same material as the punched sheet as the substrate, place the substrate horizontally in a windless and airtight environment, mark the origin and a reference line of fixed length on the substrate with a laser pointer, and the...

Embodiment 3

[0077] A production process for electric motor punching. On the basis of Example 1E, a flow aid is added to the raw material of the punching liquid, and the flow aid is graphene or a derivative of graphene. The raw materials of blanking fluid are assisted in mixing under ultrasonic vibration, so that the flow aid can be dispersed evenly. The composition and dosage of the flow aid and the test results of the self-flowing paving of the blanking fluid and the test results of the insulation resistivity of the cut surface are as follows.

Abstract

the invention relates to motor punching sheets and discloses a production process of a motor punching sheet, The invention solves the problem that the blanking times of the prior art are more and theproduction energy consumption is higher, and the technical scheme points out a production process of the electric motor blanking. The blanking of the plate material comprises the following steps: S1,blanking the plate material by a punching machine, blanking to obtain the stator and rotor initial plate material, and simultaneously blanking the stator and rotor initial plate material to determinethe outer edge contour of the sub-blanking preform; 2, punching by a punching machine, punching that stator and rotor initial plate to establish the inner edge contour and the process driving keyway,obtaining the inner edge contours of the stator punching piece and the rotor punching piece preform, obtaining the stator punching piece preform and the second punching piece; S3: punching the inner edge contour and outer edge contour of the rotor blanking preform by the punching machine to obtain the rotor blanking preform, thereby reducing the blanking times necessary and reducing the energy consumption of the equipment.

Description

technical field [0001] The invention relates to motor punching, in particular to a production process for motor punching. Background technique [0002] Motor punching sheet is a common part in the motor, and multiple motor punching sheets are stacked to form a motor rotor magnet or a motor stator magnet. For example, the Chinese patent "Punching and stamping process of stator and rotor of wind power generator" whose application publication number is CN101860134A includes the following steps: (1) blanking of stator and rotor light sheet; Light sheet punching stator outer circle profile, process drive keyway and punching process hole; (2) Stator slot punching: based on process drive key and punching process hole, single punch stator slot shape; (3) Rotor punching Chip processing: Based on the punching process hole, the rotor shaft hole, rotor eccentric outer circle, rotor ventilation hole and rotor middle groove are synchronously duplex punched. [0003] Its shortcoming is t...
