Abstract

The invention relates to a flywheel vibration-reducing system inner fluted disc fine blanking die which comprises an upper die body and a lower die body. The upper die body comprises an upper die body frame plate, an upper die body base plate, a convex die fixing plate and an unloading plate, a punch penetrates through the convex die fixing plate and the unloading plate, the punch comprises a supporting portion at an upper end and a work portion at a lower end, the supporting portion is wider than the work portion, the side face of the work portion is provided with an omega-shaped knife edge, the knife edge is machined through electric pulses, and the surface of the punch is hardened through TiCN-PVD. The flywheel vibration-reducing system inner fluted disc fine blanking die has the advantages that precision and strength of the punch are high, the service life of the punch is prolonged, and precision of the die is improved.

Description

Fluted disc fine blanking die in flywheel vibration insulating system
Technical field
The present invention relates to fluted disc fine blanking die in a kind of flywheel vibration insulating system.
Background technology
The original material adopting of drift is Cr12MoV, and surface adopts TD to process, and structure is open type, and such processing easily makes drift deform, and directly affects the precision of mould.
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 fluted disc fine blanking die in a kind of flywheel vibration insulating system.
The present invention solves the technical scheme that its technical problem adopts: fluted disc fine blanking die in a kind of flywheel vibration insulating system, comprise upper die and lower die, patrix comprises patrix frame plate, be connected in patrix frame plate below upper die plate, be connected in upper die plate below punch retainer, be connected in the stripper of punch retainer below, in punch retainer and stripper, be penetrated with drift, in punch retainer, be provided with the Compress Spring that is connected to stripper upper surface;
Counterdie comprises counterdie frame plate, be connected in counterdie frame plate top counterdie backing plate, be installed on the die mold insert of counterdie backing plate top;
Drift comprises the operate portions of support portion and the lower end of upper 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 to 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 cutaway 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.
The specific embodiment
The invention will be further described in conjunction with specific embodiments now, and following examples are intended to illustrate the present invention rather than limitation of the invention further.
Fluted disc fine blanking die in a kind of flywheel vibration insulating system as shown in Figures 1 to 3, comprise upper die and lower die, patrix comprises patrix frame plate 1, be connected in the upper die plate 2 of patrix frame plate 1 below, be connected in upper die plate 2 belows punch retainer 3, be connected in the stripper 5 of punch retainer 3 belows, in punch retainer 3 and stripper 5, be penetrated with drift 4, in punch retainer 3, be provided with the Compress Spring that is connected to stripper 5 upper surfaces;
Counterdie comprises counterdie frame plate 9, be connected in the counterdie backing plate 8 of counterdie frame plate 9 tops, be installed on the die mold insert 6 of counterdie backing plate 8 tops;
Drift 4 comprises the operate portions 11 of the 10He lower end, support portion of upper 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 to process, drift 4 surfaces adopt PVD cure process, and drift 4 surfaces adopt heat treatment.Support portion 10 is become closed from open type, play booster action, prevents drift distortion.The precision that has guaranteed drift is processed in electric pulse processing.
Drift 4 surfaces adopt TiCN-PVD cure process, and the hardness of drift 4 is HRC56-58, guarantees the intensity of drift, has reached the requirement increasing the service life.
The above-mentioned foundation desirable embodiment of the present invention of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this invention technological thought, carry out various change and modification completely.The technical scope of this invention is not limited to the content on description, must determine its technical scope according to claim scope.
