Piece prefabricated component.
By using above-mentioned technical proposal, being punched for the first time in punching machine with the outer profile of stator punching prefabricated component is to cut
Mouthful, rotor just flitch is obtained, and separate the first flitch of rotor mutually with the waste material of plate；In second of punching machine punching with
The interior of stator punching prefabricated component is used as notch inside along profile, obtains customization punching prefabricated component and prefabricated for being punched rotor punching
Second blanking part of part, then and carry out third time punching, using the outer profile of rotor punching prefabricated component, it is interior along profile as cutting
Mouthful, rotor punching prefabricated component is obtained, thus punching machine punching number is three in blanking process, reduces necessary punching number, reduces
Equipment energy consumption, and simplification of flowsheet improve production efficiency to shorten life cycle of the product.
Preferably, when the sheet metal forming stator punching prefabricated component or rotor punching prefabricated component, and the stator rushes
The outer profile of piece prefabricated component or the interior of rotor punching prefabricated component rush jagged along profile, and the shape two sides of the notch are not right
Claim.
By using stator punching prefabricated component and rotor punching prefabricated component that above-mentioned technical proposal, sheet metal forming go out, cut
Mouthful place along cutting out direction depressed deformation in a state of excitement, after subsequent processing on the stator punching and rotor punching of corresponding acquisition there are still
The depressed deformation of incision, in stator punching and rotor punching overlapping assembling, it should be noted that cutting adjacent two motor stamping
Stomatodeum falls into direction and wants identical, and existing motor stamping is thin and is arranged about adjusting to a line, it is difficult to differentiate, and be punched out in this technique
Notch, can according to the left-right position of the anisopleual shape of notch, can determine whether distinguish punching prefabricated component punching face, Jin Erbao
It demonstrate,proves stator punching and rotor punching overlapping assembling is correct, improve the packaging efficiency of stator punching and rotor punching.
Preferably, the breach quantity is two, and is symmetrical arranged about punching prefabricated component geometric center.
By using above-mentioned technical proposal, guarantees that punching prefabricated component center of gravity is overlapped with geometric center, avoid punching prefabricated component
Center of gravity is not overlapped with center of rotation and causes to tremble under high-speed rotation when use.
Preferably, the surface treatment is included in punching preform surfaces coating insulating coating, the punching foreboard
Material upper surface first sprays punching liquid, the punching liquid the following raw material and its mass fraction:
100 parts of water,
20-30 parts of film forming agent,
Film forming agent is aluminium dihydrogen phosphate or zinc dihydrogen phosphate.
By using above-mentioned technical proposal, liquid is punched in plate surface and sprawls and infiltrate plate surface, forms liquid film.Work as punching
When sanction, upper and lower mould drives edge of a knife impact plate to have the surface of liquid film, rapidly compresses and squeeze a large amount of thermal energy of generation, plate
Material and liquid film are brought rapidly up, and promote the biphosphate salt hydrolysis in liquid film, generate phosphoric acid, and phosphoric acid is reacted with the iron of plate surface,
