Abstract
The invention discloses a kind of production technology of rotor for electromotor set, comprise the following steps：Blanking stretches punching integer trimming, wherein, stretch through punching press completion, and complete at least through two steps, during supply drawing oil, the oil supply time is not less than 5s, and drawing velocity is 400 ~ 500mm/s.By stretching progressively, the speed of rational punching press using drawing oil and when controlling the oil supply time and stretching, so that the thickness of rotor set is controlled effectively, 0.3mm or so can be reduced to, it is effective to reduce noise, vibrations and the energy waste brought because rotor set rotary inertia is larger, more have practical value.
Description
Technical field
The present invention relates to a kind of production technology of rotor for electromotor set, belong to field of motor manufacturing.
Background technology
Fixed part is called stator in motor, and the static main pole of paired DC excitation has been installed thereon；And
Rotating part installs armature winding thereon armature core, and induced electromotive force is produced after energization, and electricity is produced after serving as rotating excitation field
Magnetic torque carries out energy conversion, and in general, often structure is complex for rotor, except performance requirement strictly in addition to, magnetic pole should pole
To be firmly fixed to the outside of rotating shaft.
Although the structure of current rotor set is relatively simple, because motor speed is higher, its relative dimensions can be directly influenced
The performance of motor.The thickness of the rotor set for being produced at present is larger, generally 05 ~ 0.8mm, in same error range
Interior, thickness is bigger, and the rotary inertia brought during rotation is bigger, can cause unnecessary noise and vibrations, and rotor set
Quality is bigger, and the energy for driving it to be wasted when rotating is more.
In view of the defect that the production technology of above-mentioned existing rotor set is present, the present inventor is based on being engaged in such product engineering
Using abundant for many years practical experience and professional knowledge, and coordinate the utilization of scientific principle, be actively subject to research and innovation, to found one
The production technology of rotor for electromotor set is planted, it is had more practicality.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of production technology of rotor for electromotor set, including blanking-drawing
- the operation such as punching-integer-trimming is stretched, by stretching progressively, rational using drawing oil and when controlling the oil supply time and stretching
The speed of punching press so that the thickness of rotor set is controlled effectively, it is possible to decrease arrive 0.3mm or so, effectively reduces because turning
Sub-set quality is larger and brings noise, vibrations and energy waste.
The technical scheme is that：A kind of production technology of rotor for electromotor set, comprises the following steps：
Blanking-stretching-punching-integer-trimming,
Wherein, stretch through punching press completion, and at least through two steps complete, during supply drawing oil, the oil supply time is not less than
5s, drawing velocity is 400 ~ 500mm/s.
Further, just integer is carried out after the completion of stretching, so as to ensure the circularity requirement of rotor set.
Further, just integer is completed by least two steps.
Further, the punching press time of punching is 0.3 ~ 0.5s.
Further, after the completion of trimming, inspection mistake is carried out, project includes that the top surface of rotor set is vertical with side by mistake for inspection
Degree, the circularity of the rotor set, punching edge is high through the degree of crook after integer, rotor set wall thickness and rotor set
Degree.
After employing above-mentioned technical proposal, the present invention has following beneficial effect：
1st, by stretching progressively, the speed of rational punching press using drawing oil and when controlling oil supply time and stretching so that turn
The thickness of sub-set is controlled effectively, it is possible to decrease arrive 0.3mm or so, effectively reduces and is brought because rotor set quality is larger
Noise, vibrations and energy waste；
2nd, by first integer, product quality is controlled in the process, reduce because of the percent defective that error accumulation is brought, multistep fine setting
First integer so that the circularity of product is higher, can effectively reduce the rotary inertia during rotor is enclosed within rotation process；
3rd, the punching press time of punching is controlled, the quality of bore edges can be improved, reduce burr.
Brief description of the drawings

Specific embodiment
In order that those skilled in the art more fully understand the technical scheme in the present invention, below in conjunction with of the invention real
The accompanying drawing in example is applied, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described implementation
Example is only a part of embodiment of the invention, rather than whole embodiments.Based on the embodiment in the present invention, this area is common
The every other embodiment that technical staff is obtained under the premise of creative work is not made, should all belong to protection of the present invention
Scope.
A kind of production technology of rotor for electromotor set, comprises the following steps：Blanking-stretching-punching-integer-trimming, its
In, stretch through punching press completion, and complete at least through two steps, during supply stretch oil, wherein, the proportioning of drawing oil and pure water
It is 1:2, lubricant effect is uniform, and the oil supply time is 5s, and drawing velocity is 409mm/s, and just integer is carried out after the completion of drawing process, right
The circularity of rotor set is strictly controlled, so as to effectively avoid the excessive rotary inertia of the generation in rotation process, is reduced
Vibrations and noise, wherein just integer process is completed by two steps, the just integer operation of each step is finely adjusted to shape, effectively drops
The low percent defective brought by error accumulation.
In order to ensure that rotor covers the smoothness at edge, the punching press time for setting punch process is 0.5s, is after the completion of punching
Facilitate follow-up integer and trimming, switching process can be arranged as required to.
The main purpose of integer process is that the edge that will be bent after the completion of punching is repaiied directly by the form of punching press, therefore should
Process can be repeated several times to be carried out, so as to ensure the effect of integer.After the completion of trimming process, inspection mistake is carried out, project includes turning by mistake for inspection
The top surface of sub-set and the perpendicularity of side, the circularity of rotor set, punching edge are thick through the degree of crook after integer, rotor set wall
Degree and rotor cover height.
