Abstract
The utility model relates to a two drift stamping die, including base, upper punch seat, die frame, upper punch headstock, upper punch, upper plunger, down stroke headstock, lower plunger, down stroke needle, the die frame is gone up and is provided with the nib with upper plunger, the lower plunger department of correspondence, and nib top equals with the upper plunger external diameter with the internal diameter that the upper plunger corresponds the department that nib part down equals with the lower plunger external diameter with the internal diameter that the lower plunger corresponds the department. During the in -service use, correspond the position with rising to the nib on the lower plunger earlier, and then powder filler in the nib that corresponds with upper plunger, lower plunger on the die frame to compress tightly in the nib, the start -up upper plunger pushes down can. Because the utility model discloses a hardness is greater than the material producing down stroke needle of die frame, upper plunger, lower plunger, and dispersive stress that can be fine has improved the yield of product, and product density behind the sintering is even, stable quality.
Description
Technical field
The utility model relates to production equipment field, specifically two punch mould.
Background technology
Mould be in industrial production in order to injection moulding, blowing, extrude, various mould and instrument that the method such as die casting or forging forming, smelting, punching press, stretching obtains required product.In brief, mould is used to the instrument of formed article, and this instrument is made up of various part, and different moulds is made up of different parts.It realizes the processing of article profile mainly through the change of institute's moulding material physical state.Press the difference of shaping material, mould can be divided into metal die and nonmetal mould.Metal die is divided into again: casting mould (non-ferrous metal die casting, steel casting) and forging mold etc.
The processing technology classification of processing metal pressed by mould, and conventional has: stamping die, comprises blanking die, bending die, Drawing Die, flange die, reducing die, forcer, bulging die, sizing die etc.; Forging die, comprises die forging forging die, upsetting die etc.; And extrusion die and compression mod.
In die cast, by powder pressing to obtain tight preformed member, carry out manufacturing machine parts succeeded by sintering and can relate to use uniaxial compression machine, described uniaxial compression machine is made up of the punch die be included in shell and drift, pouring powders in described punch die, described drift engages in shell, with compressing powder.These stamping machines are with comparatively faster cadence operations.There is many application: it can relate to metal or ceramic machinery part, such as, gear, magnet, fuel pellet etc.But this type of die casting is when the demoulding, and because compression produces radial stress in part, the demoulding can discharge described radial stress.Therefore, very easily break or rupture in the aperture place of part, and in addition, die casting often has the marked change of radial dimension.In fact, compression is uneven.
Utility model content
The utility model, just for above the deficiencies in the prior art, provides a kind of two punch moulds that effectively can reduce the stamping parts defect caused at product stripping therebetween.
The utility model is achieved through the following technical solutions:
Two punch mould, comprise pedestal, rush-up seat, die punching frame, upper punch headstock, upper punch, upper plunger, undershoot headstock, lower plunger, undershoot needle, it is characterized in that upper plunger, lower plunger is corresponding up and down, upper plunger is fixed on upper punch, upper punch is arranged on upper punch headstock, upper punch headstock is fixed on rush-up seat, upper punch can press down under the driving of upper punch headstock, undershoot needle is fixed in lower plunger, lower plunger is arranged on undershoot headstock, with upper plunger on die punching frame, lower plunger corresponding position is provided with nib, nib upper part is equal with upper plunger external diameter with the internal diameter of upper plunger corresponding position, nib lower part is equal with lower plunger external diameter with the internal diameter of lower plunger corresponding position.The through hole corresponding with undershoot needle is provided with in the middle of upper plunger.Undershoot needle hardness is greater than die punching frame, upper plunger, lower plunger.Die punching frame section is 7 fonts.Upper plunger, lower plunger external diameter are equal.
Actual when using, first lower plunger is risen to nib correspondence position, and then powder filler in nib corresponding with upper plunger, lower plunger on die punching frame, and be pressed in nib, start upper plunger and press down.Due to the utility model adopt hardness be greater than die punching frame, upper plunger, lower plunger material make undershoot needle, can well dispersive stress, improve the yield of product, product is even density after sintering, stay in grade.
The utility model structure is simple, easy to use.
Accompanying drawing explanation
In accompanying drawing, Fig. 1 is the utility model structural representation, wherein:
1-pedestal, 2-rush-up seat, 3-die punching frame, 4-upper punch headstock, 5-upper punch, 6-upper plunger, 7-undershoot headstock, 8-lower plunger, 9-undershoot needle.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Two punch mould, comprise pedestal 1, rush-up seat 2, die punching frame 3, upper punch headstock 4, upper punch 5, upper plunger 6, undershoot headstock 7, lower plunger 8, undershoot needle 9, it is characterized in that upper plunger 6, lower plunger about 8 is corresponding, upper plunger 6 is fixed on upper punch 5, upper punch 5 is arranged on upper punch headstock 4, upper punch headstock 4 is fixed on rush-up seat 2, upper punch 5 can press down under the driving of upper punch headstock 4, undershoot needle 9 is fixed in lower plunger 8, lower plunger 8 is arranged on undershoot headstock 7, with upper plunger 6 on die punching frame 3, lower plunger 8 corresponding position is provided with nib, nib upper part is equal with upper plunger 6 external diameter with the internal diameter of upper plunger 6 corresponding position, nib lower part is equal with lower plunger 8 external diameter with the internal diameter of lower plunger 8 corresponding position.The through hole corresponding with undershoot needle 9 is provided with in the middle of upper plunger 6.Undershoot needle 9 hardness is greater than die punching frame 3, upper plunger 6, lower plunger 8.Die punching frame 3 section is 7 fonts.Upper plunger 6, lower plunger 8 external diameter are equal.
Actual when using, first lower plunger 8 is risen to nib correspondence position, and then powder filler in nib corresponding with upper plunger 6, lower plunger 8 on die punching frame 3, and be pressed in nib, start upper plunger 6 and press down.Due to the utility model adopt hardness be greater than die punching frame 3, upper plunger 6, lower plunger 8 material make undershoot needle 9, can well dispersive stress, improve the yield of product, product is even density after sintering, stay in grade.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
