Abstract
The invention relates to the field of manufacture of motors, in particular to a punching processing technology of motor stator and rotor laminations. The punching processing technology solves the problems that the stator and rotor laminations which have smaller air gap and are stamped by the existing punching processing technology of the motor stator and rotor laminations can not meet the requirements on surface quality and burr height of the laminations, and the processing steps of the punching processing technology of the motor stator and rotor laminations are as follows: (1) blanking the stator and rotor laminations: punching a shaft hole, a key slot, all vent holes and an outer circle of the stator lamination; (2) carrying out positioning by the shaft hole and the key slot, carrying out single punching of a stator slot, ensuring the size of the inner diameter of the stator lamination, cutting edge and separating the outer circuit of a rotor; and (3) carrying out the positioning by the shaft hole and the key slot and carrying out the single punching of a rotor lamination slot. The punching processing technology improves the quality of the rotor lamination, and the quality of the processed laminations can fully meet the technical requirements, thereby not only improving production efficiency, but also reducing manufacturing cost of molds, saving a large amount of punching and transferring working time.
Description
Technical field
The present invention relates to field of motor manufacturing, specifically is a kind of punch machining process of electric machine rotor punching.
Background technology
The punch process operation of electric machine rotor punching is the important procedure during motor is made.At present, the existing electric machine rotor sheet punching press processing technology flow process of generally using is as follows:
(1) rotor punching blanking: towards axis hole, keyway, all air vents, stator punching cylindrical;
(2) with axis hole and keyway location, multiple towards stator slot;
(3) with axis hole and keyway location, guarantee the stator punching internal diameter size, separate the rotor punching;
(4) with axis hole and keyway location, one-shot rotor punching groove, side cut separation rotor cylindrical (air gap).
But the time with the less rotor punching of this punch machining process punching out air gap, existence can't be satisfied the problem of punching surface quality and burr height requirement, reason is: because air gap is less between the electric machine rotor punching, when adopting existing technology one-shot rotor punching groove, side cut separation rotor cylindrical (air gap), the waste material that downcuts easily is attracted on the punch die, cause the rotor punching surface of processing that impression and scuffing are arranged, make the rotor punching burr height seriously overproof, die surface is easy damaged also.
Summary of the invention
The present invention exists and can't satisfy the problem that punching surface quality and burr height require in order to solve the less rotor punching of air gap with existing electric machine rotor sheet punching press processing technology punching out, and a kind of punch machining process of electric machine rotor punching is provided.
The present invention adopts following technical scheme to realize: the punch machining process of electric machine rotor punching, and procedure of processing is as follows:
(1) rotor punching blanking: towards axis hole, keyway, all air vents, stator punching cylindrical;
(2) with axis hole and keyway location, the one-shot stator slot guarantees the stator punching internal diameter size, side cut separation rotor cylindrical (air gap);
(3) with axis hole and keyway location, one-shot rotor punching groove.
Compared with prior art, punch machining process of the present invention is improved on existing technology basis, original multiple with one-shot stator slot replaceable operation chain towards the stator slot operation, and in the one-shot stator slot, finish and cut air gap, saved stator and rotor punching separation circuit, avoided producing the too small waste material that easily is attracted on the punch die in process, guaranteed the surface quality of rotor punching, the punching burr also can satisfy specification requirement; Reduce by two secondary compound moulds simultaneously: multiple towards stator channel mould and splitting die, make die cost be reduced to 1.2 ten thousand yuan by original 200,000 yuan, die manufacturing cycle also shortened to one month by 3 months.Punch machining process of the present invention not only is satisfied with the rotor punching processing of small air gap, is satisfied with the processing of the electric machine rotor punching of air gaps too.
Punch machining process of the present invention has improved the quality of rotor punching, and the punching quality that processes satisfies specification requirement fully, has not only improved production efficiency, and has reduced the mould manufacturing expense, and can save the man-hour of many punching presses, transhipment.
The specific embodiment
The punch machining process of electric machine rotor punching, procedure of processing is as follows:
(1) rotor punching blanking: towards axis hole, keyway, all air vents, stator punching cylindrical;
(2) with axis hole and keyway location, the one-shot stator slot guarantees the stator punching internal diameter size, side cut separation rotor cylindrical (air gap);
(3) with axis hole and keyway location, one-shot rotor punching groove.
Claims (1)
1, a kind of punch machining process of electric machine rotor punching is characterized in that procedure of processing is as follows:
(1) rotor punching blanking: towards axis hole, keyway, all air vents, stator punching cylindrical;
(2) with axis hole and keyway location, the one-shot stator slot guarantees the stator punching internal diameter size, side cut separation rotor cylindrical;
(3) with axis hole and keyway location, one-shot rotor punching groove.
