Abstract

A powder metallurgy pressing die for producing magnetic poles of an automobile generator comprises a pressing upper die, a pressing lower die, a peripheral die, an inner hole lower die and an anchoring flange. The inner hole lower die penetrates through two holes of the pressing lower die, the pressing lower die is in clearance fit with the peripheral die which is fixed on a seat for placing dies through the anchoring flange, and the shape of an end face of the pressing upper die is matched with that of the magnetic pole. The powder metallurgy pressing die can finish press molding process in one step, thereby reducing complexity of existing machining operations, decreasing the rejection rate and the damage rate of dies, further improving work efficiency and reducing production cost. The powder metallurgy pressing die can be applied to mass production of magnetic poles of the automobile generator and increases benefits of enterprises.

Description

A kind of powder metallurgy pressing mould of making the automobile current generator magnetic pole
Technical field
The utility model belongs to powder metallurgy die manufacturing technology field, is specifically related to a kind of powder metallurgy pressing mould that is used to make the automobile current generator magnetic pole.
Background technology
The automobile current generator magnetic pole is the vital part on the automobile current generator, its structure as shown in Figure 7, it is complex-shaped, dimensional accuracy and inherent quality require than higher, manufacture difficulty is big.At present this magnetic pole is mainly made by mach mode by steel part forging and pressing back, and the method for machining normally substep punching press and machine cuts finish, exist and expend man-hour and consumes energy reaches shortcomings such as complex process more.Therefore be necessary to design a kind of relevant powder metallurgy die, realize the one time punching molded and production in enormous quantities of powder metallurgy.
The utility model content
At the deficiency that above-mentioned prior art exists, the utility model provides a kind of powder metallurgy pressing mould of making the automobile current generator magnetic pole, can't be by problems such as machining one-shot forming and production in enormous quantities to overcome.
A kind of powder metallurgy pressing mould of making the automobile current generator magnetic pole, comprise compacting patrix, compacting counterdie, peripheral mould, endoporus counterdie, anchoring flange, the endoporus counterdie is through in two holes of compacting counterdie, compacting counterdie and peripheral die clearance cooperate, and peripheral mould is fixed on the seat platform of placing mould by anchoring flange.
The end surface shape of described compacting patrix is consistent with the shape of magnetic pole.
Advantage of the present invention is: 1, by structure described in the utility model, make pole surface have preferable flatness, more can accommodate the fine burr phenomenon that is produced because of the liftout interporal lacuna; 2, the utility model utilizes powder metallurgy pressing, and is one time punching molded, reduced the complexity of in the past using machining, reduced percent defective and mould spoilage, and then improved production efficiency, reduced production cost; 3, utilize the utility model, can produce the automobile current generator magnetic pole in enormous quantities, increased benefit to enterprise.

Fig. 6 is the vertical view of anchoring flange described in the utility model.
Fig. 7 is the structural representation of the generator magnetic pole of the utility model compression moulding.
The specific embodiment
Now in conjunction with the accompanying drawings, the utility model is further described.
Shown in Fig. 1-6, a kind of powder metallurgy pressing mould of making the automobile current generator magnetic pole described in the utility model, comprise compacting patrix 1, compacting counterdie 2, peripheral mould 3, endoporus counterdie 4, anchoring flange 5, endoporus counterdie 4 is through in two holes of compacting counterdie 2, compacting counterdie 2 and peripheral mould 3 matched in clearance, periphery mould 3 is fixed on the seat platform of placing mould by anchoring flange 5, and the end surface shape of described compacting patrix 1 is consistent with the shape of the magnetic pole that is pressed into.Wherein suppress patrix 1 and be in the compacting in order to from top airtight compacting counterdie 2, transmit the parts of pressure to powder from the top down, with reference to Fig. 2, compacting patrix 1 of the present utility model is according to magnetic pole end face shaped design, and cooperates compacting counterdie 2 and peripheral mould 3; Compacting counterdie 2 and endoporus counterdie 4 cooperate the main body of common compression moulding magnetic pole and two circular holes on the main body; Periphery mould 3 mainly is the outer rim shape that is used for the moulding magnetic pole, and peripheral mould 3, compacting counterdie 2 cooperate from bottom to top to powder transmission pressure.
The magnetic pole pressing process is divided into dress powder, compacting, demoulding three phases.During powder filling, compacting patrix 1 does not enter compacting counterdie 2, with compacting counterdie 2 is benchmark, equal the height that compression ratio multiply by product according to the height of dress powder and determine each section height, and adjust compacting counterdie 2, peripheral mould 3, endoporus counterdie 4 to dress powder position, endoporus counterdie 4 positions will be higher than compacting counterdie 2, feed shoe filling powder.During compacting, compacting patrix 1 enters compacting counterdie 2 downwards, and compacting counterdie 2 and endoporus counterdie semi-finals system float to the pressing position, and with peripheral mould 3, compacting patrix 1 acting in conjunction press forming.During the demoulding, adopt the pull-down demoulding, promptly suppress patrix 1 and rise, compacting counterdie 2 and endoporus counterdie 4 are drop-down, arrive demoulding position, make the product magnetic pole deviate to suppress counterdie 2.Adopt the compacting tool set described in the utility model can a compression moulding, and can produce in enormous quantities.
