Abstract
The utility model relates to a sheet punching die of a motor. The sheet punching die comprises a lower die plate, a female die, a male die, a male-die fixing plate, a die shank and discharging rubber. The discharging rubber is mounted on the outer side of the male die, an upper die seat is mounted above the male-die fixing place, a discharge plate is arranged under the discharge rubber, a fixing bolt is penetratingly arranged in the upper die seat, the male-die fixing plate and the discharge plate from top to bottom, a guide sleeve is arranged on the lower surface of the upper die seat, a bushing is arranged on the upper surface of the lower die seat, and a guide post is arranged between the guide sleeve and the bushing. The sheet punching die has the advantages that guidance is added between upper and lower dies, and rigidity in discharging is achieved.
Description
Technical field
The utility model relates to a kind of motor stamping mould.
Background technology
In motor, punching quality directly affects the overall performance of motor.The punching of micromachine stator and rotor is most one-shot technique that adopts in the past.Punching technique is: blanking (a time 3); One-shot stator piece; One-shot rotor sheet.While rushing stator punching, with excircle orientation, use calibration chain wheel calibration.Adopt die shank and slider of punch shaft hole matching location and installation mould.
With discharging rubber, be tightly placed on punch and utilize the bounce producing after rubber pressurized to carry out discharging, low and unstable through the long-term punching quality of using this kind of structure of discovery to go out.Its main cause has: (1) punch die is with punch shaft to being connected without constraint, and jet-bedding process easily causes grooved skew; (2) positioning precision is low: the accuracy of manufacture of excircle orientation device chain wheel and the quality of fit of punching are low; (3) discharging rubber, for a long time after work, causes stripping force to reduce, and even causes that punch gnaws mouth; (4) punch and matrix gap is difficult to meet technological requirement, because whether gap is rationally guaranteed by operative employee by rule of thumb; (5) because punch is longer, less stable.Thereby easily cause inclined to one side punching, cause burr overproof.
Utility model content
The technical problems to be solved in the utility model is: based on the problems referred to above, provide a kind of motor stamping mould.
The utility model solves the technical scheme that its technical problem adopts: a kind of motor stamping mould, comprise lower bolster, die, punch, punch retainer, die shank and be installed on the discharging rubber in punch outside, punch retainer top is provided with upper bolster, the below of discharging rubber is provided with stripper, in upper bolster, punch retainer and stripper, run through from top to down and be provided with hold-down screw, upper bolster lower surface is provided with guide pin bushing, lower bolster upper surface is provided with lining, between guide pin bushing and lining, guide pillar is installed.
The beneficial effects of the utility model are: mould has increased guiding between upper and lower mould, and are rigidity discharging.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Wherein: 1. lower bolster, 2. lining, 3. guide pillar, 4. die, 5. stripper, 6. punch, 7. discharging rubber, 8. punch retainer, 9. guide pin bushing, 10. hold-down screw, 11. upper bolsters, 12. die shanks.
The specific embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
A kind of motor stamping mould as shown in Figure 1, comprise lower bolster 1, die 4, punch 6, punch retainer 8, die shank 12 and be installed on the discharging rubber 7 in punch 6 outsides, punch retainer 8 tops are provided with upper bolster 11, the below of discharging rubber 7 is provided with stripper 5, in upper bolster 11, punch retainer 8 and stripper 5, run through from top to down and be provided with hold-down screw 10, upper bolster 11 lower surfaces are provided with guide pin bushing 9, and lower bolster 1 upper surface is provided with lining 2, between guide pin bushing 9 and lining 2, guide pillar 3 are installed.
Guide pillar 3 is installed between guide pin bushing 9 and lining 2 and makes to have increased guiding between upper and lower mould, in upper bolster 11, punch retainer 8 and stripper 5, run through being from top to down provided with hold-down screw 10 to make discharging be rigidity discharging.
The above-mentioned foundation desirable embodiment of the present utility model of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this utility model technological thought, carry out various change and modification completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to claim scope.
