Abstract

The invention relates to a motor stamping die. The motor stamping die comprises a lower die plate, a female die body, a male die body, a male die fixing plate, a die handle and discharging rubber installed on the outer side of the male die body, wherein an upper die base is installed above the male die fixing plate, a discharging plate is arranged below the discharging rubber, a fixing screw penetrates through the upper die base, the male die fixing plate and the discharging plate from top to bottom, a guide sleeve is arranged on the lower surface of the upper die base, a lining is arranged on the upper surface of the lower die plate, and a guide pillar is installed between the guide sleeve and the lining. The motor stamping die has the advantages that guiding is achieved between an upper die body and a lower die body, and rigid discharging is achieved.

Description

A kind of motor stamping mould
Technical field
The present invention 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 in the past adopts one-shot technique.Punching technique is: blanking (a time 3); One-shot stator piece; One-shot rotor sheet.With excircle orientation when rushing stator punching, with calibration chain wheel calibration.Adopt die shank and slider of punch shaft hole matching location and installation mould.
With discharging rubber be tightly placed in punch utilizes rubber pressurized after the bounce that produces carry out discharging, find that the punching quality that this kind of structure is gone out is low and unstable through Long-Time Service.Its main cause has: (1) punch die and punch shaft are to being connected without retraining, and jet-bedding process easily causes grooved skew; (2) positioning precision is low: namely the accuracy of manufacture of excircle orientation device chain wheel and the quality of fit of punching low; (3) after discharging rubber works for a long time, cause stripping force to reduce, even cause punch to gnaw mouth; (4) clearance between matrix and punch is difficult to meet technological requirement, because whether gap is rationally ensured by operative employee by rule of thumb; (5) because punch is longer, less stable.Thus easily cause inclined punching, cause burr overproof.
Summary of the invention
The technical problem to be solved in the present invention is: based on the problems referred to above, the invention provides a kind of motor stamping mould.
The present invention 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 outside punch, above punch retainer, upper bolster is installed, the below of discharging rubber is provided with stripper, run through from top to down in upper bolster, punch retainer and stripper 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, is provided with guide pillar between guide pin bushing and lining.
The invention has the beneficial effects as follows: mould adds guiding between upper and lower mould, and be rigidity discharging.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is structural representation of the present invention.
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.
Detailed description of the invention
The invention will be further described in conjunction with specific embodiments now, and following examples are intended to the present invention instead of limitation of the invention further are described.
A kind of motor stamping mould as shown in Figure 1, the discharging rubber 7 comprising lower bolster 1, die 4, punch 6, punch retainer 8, die shank 12 and be installed on outside punch 6, upper bolster 11 is installed above punch retainer 8, the below of discharging rubber 7 is provided with stripper 5, run through from top to down in upper bolster 11, punch retainer 8 and stripper 5 and be provided with hold-down screw 10, upper bolster 11 lower surface is provided with guide pin bushing 9, and lower bolster 1 upper surface is provided with lining 2, is provided with guide pillar 3 between guide pin bushing 9 and lining 2.
Guide pillar 3 is installed between guide pin bushing 9 and lining 2 make to add guiding between upper and lower mould, in upper bolster 11, punch retainer 8 and stripper 5, runs through being provided with hold-down screw 10 and making discharging be rigidity discharging from top to down.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on description, must determine its technical scope according to right.
