Description
Technical field
Technical field of motor manufacture is the utility model is related to, specifically a kind of rotor punching punching-pressing composite mould.
Background technology
Motor is a kind of electric equipment for being widely used in industrial production and life, and motor includes stator, rotor, turned
The parts such as axle, end cap, formed by stamping forming punching superposition compacting when stator, rotor manufacture, generally be intended to after sheet punching press
The separation of rotor punching is carried out using splitting die, then rotor punching external diameter is processed, so as to after installing in rotor and
Appropriate air gap is reserved between stator, this processing mode repeatedly positions to punching, and the precision of each punching processing has
Larger error, flatness, the regularity of groove profile of iron core are poor after superposition compacting, leverage the matter of motor manufacturing
Amount.
The content of the invention
Technical problem to be solved in the utility model is：Iron core flatness can be improved by providing one kind, groove profile it is neat
Property, the good rotor punching punching-pressing composite mould of motor quality.
Technical scheme is used by the utility model：A kind of rotor punching punching-pressing composite mould, including middle part axle are provided
Hole positioning mould, in addition to for the groove profile mould at punching punching circumferential edges, damping casement and bar shaped air gap mould, described damping
Casement and bar shaped air gap mould are located at the same side of groove profile mould, and bar shaped air gap mould is located at using the center of middle part axis hole positioning mould as circle
The heart, the center of circle to bar shaped air gap mould center is on the circumference of radius, the spacing between bar shaped air gap mould and damping casement is a groove
The distance of pattern and damping casement.
The width of the bar shaped air gap mould determines according to motor gas-gap size.
After above structure, compared to the prior art the utility model rotor punching punching-pressing composite mould has following excellent
Point：
1st, during rotor punching punching, rotor punching and stator punching can be separated, and by between stator and rotor
Air gap punching is good, avoids rotor jet-bedding, rotor punching is separated, three processes of rotor punching Excircle machining are individually carried out, raising
Operating efficiency.
2nd, three processes are combined into a process and completed, and reduce the operation equipment of process, artificial cost.
3rd, the repositioning problem individually processed is avoided, the precision and regularity of punching groove profile are improved, and punching laminates
After shaping, integrated motor quality, performance greatly improve.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model rotor punching punching-pressing composite mould.
Fig. 2 is the lamination structure figure of the utility model rotor punching punching-pressing composite mould punching.
Embodiment
The utility model is described in detail below in conjunction with drawings and examples.
As shown in Figure 1 and Figure 2, the utility model rotor punching punching-pressing composite mould, including middle part axis hole positioning mould 4, are also wrapped
Include for the groove profile mould 1 at punching punching circumferential edges, damping casement 2 and bar shaped air gap mould 3, damp casement 2 and bar shaped air gap
Mould 3 is located at the same side of groove profile mould 1, and casement 2 is damped in figure and bar shaped air gap mould 3 is located at the right side of groove profile mould 1, bar shaped air gap
For mould 3 in using the center of middle part axis hole positioning mould 4 as the center of circle, the center of circle to the center of bar shaped air gap mould 3 is bar shaped gas on the circumference of radius
Spacing between gap mould 3 and damping casement 2 is a groove profile mould 1 and the distance for damping casement 2.
In the specific implementation, above-mentioned each mould sets concave-convex mold to the utility model, and middle part axis hole positioning mould 4 is in punching punching
The shaft hole in portion, cavity plate set the keyway in shaft hole and shaft hole side wall, and punch-pin is set and the corresponding cylinder of cavity plate and cylinder
On key.The cavity plate of groove profile mould 1 is provided with groove profile hole, damping hole and bar shaped air gap slotted eye, and groove profile hole length direction is from rotating shaft
Hole center extends to punching circumferential outer edge, and damping hole and bar shaped air gap slotted eye are located at the right side in groove profile hole, the damping after punching
Pitch-row has a certain distance from the outer rim of punching, and bar shaped air gap slotted eye is located at using middle part shaft hole center as the center of circle, the center of circle to bar
Shape air gap slotted eye center is on the circumference of radius, the spacing between bar shaped air gap slotted eye and damping hole is a groove profile hole and damping
The distance in hole.
In the specific implementation, first punching goes out a groove profile hole, damping hole and bar shaped air gap slotted eye to the utility model, rotates punching
The position of the next groove profile hole of piece punching, damping hole and bar shaped air gap slotted eye, next groove profile hole and damping hole punching be on
Locate between one bar shaped air gap slotted eye and damping hole, bar shaped air gap slotted eye can separate the rotor punching of punching, utilize this
The middle part for the rotor punching that utility model punching goes out has shaft hole and keyway, and punching circumferential edges have the groove profile circumferentially arranged
Hole, dentation is formed between groove profile hole, damping hole is located in indented region, and the width of bar shaped air gap mould 3 is according to motor gas-gap size
It is determined that.
Using the utility model punching punching, can rotor punching groove profile hole, rotor punching separation, rotor punching it is cylindrical
Three processes of processing synthesize a process, and processing cost is reduced, and crudy is improved, the folded manufactured iron core of punching
Groove profile regularity is good, is advantageous to the implementation of subsequent handling.
