Abstract

The utility model discloses a composite die special for one-step molding a motor stator punching sheet and separating a rotor punching sheet. The composite die comprises an upper die, a lower die, and a polyurethane rubber elastic system, wherein the upper die is sequentially provided with a concave die, a convex die, an upper discharge plate and a scrap pressure plate from inside to outside along a central axle hole, the lower die is sequentially provided with a lower discharge plate, a blanking hole, a concave-convex die and a scrap discharge table from inside to outside along the central axle hole. Known from the above working process, the stator punching sheet and the rotor punching sheet are wound by the die, thus the operation is convenient, the working efficiency is high, and the quality of the workpiece is ensured.

Description

Motor stator punching one-shot forming and rotor punching separate, dedicated composite die
Technical field
The utility model relates to the machine work field, is specifically related to a kind of for motor stator punching one-shot forming and rotor punching separate, dedicated composite die.
Background technology
As everyone knows, the quality of stator and rotor punching directly affects the quality of iron core pressure mounting, and quality unshakable in one's determination will have a huge impact the quality of motor product.So the ram efficiency of stator and rotor directly affects the benefit of enterprise.The general three process that adopts of the stator of industrial motor and rotor punching processing, compound blanking is gone out stator and rotor punching first, and then difference jet-bedding type.The stator of making by this processing method is with after rotor punching laminates into iron core, and stator grooved and inside and outside shaped homogeneous are poor, will affect the rule quality as grooved is irregular.If file groove, not only iron loss increases, and stator core cylindrical regularity can not guarantee that it is bad to cause the stator core cylindrical to contact with the inner circle of support, the conduction of impact heat, electric machine temperature rise height.Present method is produced stator and rotor punching not only production process is many, the cycle grows but also poor product quality, cost height.
Summary of the invention
The purpose of this utility model is: overcome the deficiencies in the prior art, provide a punching press of a kind of energy just can stamp out stator and rotor punching and can guarantee its quality requirement.
Technical solution adopted in the utility model is:
Motor stator punching one-shot forming and rotor punching separate, dedicated composite die, comprise upper die and lower die, also comprise the polyurethane rubber elastic system, described patrix outwards is provided with die, punch, loading and unloading material plate and rim charge pressing plate successively around central shaft hole, and described counterdie outwards is provided with lower stripper, material-dropping hole, concave-convex mold and the rim charge discharging platform that mates with described die, punch, loading and unloading material plate and rim charge pressing plate successively around central shaft hole.
The further technical scheme of the utility model is to be provided with the polyurethane rubber elastic system below lower stripper.
The utility model further technical scheme is that five equilibrium is interval with the first guide pillar, the second guide pillar between rim charge discharging platform and the counterdie base.
The utility model further technical scheme is, described the first guide pillar upper end is fixedly connected on the rim charge discharging platform, and the lower end is movably connected in the base of counterdie, is provided with elastic supporter between the base of rim charge discharging platform and counterdie.
The utility model further technical scheme is, the rim charge discharging platform is fixed in the second guide pillar upper end, and the lower end is provided with guide pin bushing, and is arranged in the counterdie base holes.
The beneficial effects of the utility model are:
When carrying out the punching press of stator and rotor punching with the utility model, the punching course of stator punching, rotor punching and stator grooved is incorporated into together, the transmission of recycling elastic system utilizes and is about to the stator grooved waste material punching press of rotor punching cylindrical under the continuation of patrix and falls.From the above-mentioned course of work as can be known, carry out the production of stator and rotor punching with the utility model, not only reduced manufacturing procedure, shortened the production cycle, convenient and reliable operation has reduced production cost, and the inside and outside circle of the punching of producing and grooved are neat, improve product quality, improved production efficiency.
