The present invention solves the technical scheme that its technical problem adopts: a kind of flywheel vibration insulating system internal gear disc fine blanking die, comprise upper die and lower die, patrix comprises patrix frame plate, be connected to upper die plate below patrix frame plate, be connected to punch retainer below upper die plate, be connected to stripper below punch retainer, run through in punch retainer and stripper and have drift, in punch retainer, be provided with the Compress Spring being connected to stripper upper surface;
Counterdie comprises counterdie frame plate, be connected to counterdie backing plate above counterdie frame plate, be installed on die mold insert above counterdie backing plate;
Drift comprises the support portion of upper end and the operate portions of lower end, the width of support portion is greater than operate portions, and the side of operate portions has the edge of a knife of Ω shape, and the edge of a knife adopts electric pulse processing process, punch head surface adopts PVD cure process, and punch head surface adopts TiCN-PVD cure process.
Further, the hardness of drift is HRC56-58.
The invention has the beneficial effects as follows: precision and the intensity of drift are high, extend its service life, improve the precision of mould.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is structural representation of the present invention;
Fig. 2 is the sectional view of drift;
Fig. 3 is the top view of drift.
Wherein: 1. patrix frame plate, 2. upper die plate, 3. punch retainer, 4. drift, 5. stripper, 6. die mold insert, 8. counterdie backing plate, 9. counterdie frame plate, 10. support portion, 11. operate portions.
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 flywheel vibration insulating system internal gear disc fine blanking die as shown in Figures 1 to 3, comprise upper die and lower die, patrix comprises patrix frame plate 1, be connected to upper die plate 2 below patrix frame plate 1, be connected to punch retainer 3 below upper die plate 2, be connected to stripper 5 below punch retainer 3, run through in punch retainer 3 and stripper 5 and have drift 4, in punch retainer 3, be provided with the Compress Spring being connected to stripper 5 upper surface;
Counterdie comprises counterdie frame plate 9, be connected to counterdie backing plate 8 above counterdie frame plate 9, be installed on die mold insert 6 above counterdie backing plate 8;
Drift 4 comprises the support portion 10 of upper end and the operate portions 11 of lower end, the width of support portion 10 is greater than operate portions 11, and the side of operate portions has the edge of a knife of Ω shape, and the edge of a knife adopts electric pulse processing process, drift 4 surface adopts PVD cure process, and drift 4 surface adopts heat treatment.Support portion 10 is become closed from open type, play booster action, prevents drift to be out of shape.Electric pulse processing process ensure that the precision of drift.
Drift 4 surface adopts TiCN-PVD cure process, and the hardness of drift 4 is HRC56-58, guarantees the intensity of drift, reaches the requirement increased the service life.
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.
