Abstract
The utility model discloses a shaping mould of annular sintering blanks in powder metallurgy. The shaping mould comprises an upper mould and a lower mould. The upper mould comprises an upper mould base, an upper punch and an upper mould guide pin; the upper mould guide pin is fixed on the lower end of the upper punch, the upper end of the upper punch is fixed on the upper mould base; the lower mould comprises a lower mould outer base, a lower mould inner base, an inner cylindrical core and an outer round shaping sleeve, the lower mould inner base is fixed in the lower mould outer base, the lower end of the inner cylindrical core is fixed on the lower mould inner base, the upper end of the inner cylindrical core extends into the outer round shaping sleeve, the outer round shaping sleeve is fixed on the lower mould outer base, the lower mould outer base is fixedly arranged on a lower working platform of a press machine, the lower mould inner base is connected with a lower cylinder of the press machine, and the upper mould base is connected with an upper sliding plate of the press machine. The shaping mould of the annular sintering blanks in the powder metallurgy has the advantage of high shaping efficiency compared with the traditional separated type shaping technology; the wall thickness is shaped, thus the size and the integral shape have good accuracy; and the shaped blank has small deformation quantity and good consistency, thus subsequent large-batch production organization is facilitated.
Description
Technical field: the utility model relates to a kind of shaping mould, and especially a kind of shaping mould of powder metallurgy annular type sintering blank belongs to the powder metallurgical technique technical field.
Background technology: powder metallurgy product just can become alloy after must passing through sintering circuit, and the alloy product behind the sintering is called the sintering blank.The common outer surface of its annular series products sintering blank is coarse, and shape is irregularity also, therefore just need carry out shaping processing.At present, the shaping of this series products adopted mostly in the industry simply flatten, whole in separate type methods such as circle or whole cylindrical carry out, just multifrequency time is carried out shaping step by step.At first there is the problem of inefficiency in this mode; Secondly be exactly owing to existing internal stress to make shaping effect not good through shaping distortion back; Bring many for the postorder processing of product such as hidden danger such as processing back distortion; And because the inconsistency of sintering blank inherent quality makes its shaping process also be difficult to effectively control, especially for being worth costliness and this type of higher alloy product of instructions for use, this shaping methods just seems more coarse and will lose bigger financial cost.
The utility model content: to the deficiency of above-mentioned prior art, the utility model provides a kind of shaping mould of powder metallurgy annular type sintering blank.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is: the shaping mould of powder metallurgy annular type sintering blank, form by mold and bed die.Mold comprises upper bolster, upper punch and patrix guide pillar.Described patrix guide pillar is fixed on the lower end of upper punch.The upper end of upper punch is fixed on the upper bolster.Bed die comprises seat, interior cylindrical core and cylindrical shaping cover in the outer seat of counterdie, the counterdie.Seat is fixed in the outer seat of counterdie in the described counterdie.The lower end of interior cylindrical core is fixed on the interior seat of counterdie, and the upper end extend in the cylindrical shaping cover.Cylindrical shaping cover is fixed on the outer seat of counterdie.The outer seat of counterdie is fixed on the forcing press lower table.In the counterdie under seat and the forcing press cylinder be connected.Upper bolster is connected with the upper slide of forcing press.
The beneficial effect of the utility model is: compare shaping efficient with traditional separate type shaping methods high; Increased the shaping to wall thickness, its size and monnolithic case accuracy are good; Blank deflection after the shaping is little, and the high conformity of product blank helps follow-up production in enormous quantities tissue.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
The specific embodiment:
As shown in Figure 1: the shaping mould of powder metallurgy annular type sintering blank, form by mold and bed die.Mold comprises upper bolster 7, upper punch 6 and patrix guide pillar 5.Described patrix guide pillar 5 is fixed on the lower end of upper punch 6.The upper end of upper punch 6 is fixed on the upper bolster 7.Bed die comprises seat 2, interior cylindrical core 3 and cylindrical shaping cover 4 in outer 1 of counterdie, the counterdie.Seat 2 is fixed in the outer seat 1 of counterdie in the described counterdie.The lower end of interior cylindrical core 3 is fixed on the interior seat 2 of counterdie, and the upper end extend in the cylindrical shaping cover 4.Cylindrical shaping cover 4 is fixed on the outer seat 1 of counterdie.The outer seat 1 of counterdie is fixed on the forcing press lower table.In the counterdie under seat 2 and the forcing press cylinder be connected, its effect is to be used for hauling out the blank after the shaping.Upper bolster 7 is connected with the upper slide of forcing press, is pressurizeed downwards by the upper cylinder power of giving during work, and patrix guide pillar 5 is that the location makes upper and lower die alignment when the dress mould, when the II stage begins, play the guiding role.Earlier annular type sintering blank is positioned over the top of cylindrical shaping cover 4 during shaping; Promote blanks downwards by upper punch 6 and slip into I stage stroke downwards, cylindrical shaping this moment cover 4 just carries out the shaping of contracting in the cylindrical to blank, finishes the II stage when beginning when the I stage; The inwall of blank just is set on the interior cylindrical core 3; The outer shaping of rising of circle in beginning circle in the blank carried out finishes the III stage when beginning when the II stage, just simultaneously the blank inside and outside circle is carried out shaping by cylindrical shaping cover 4 and interior cylindrical core 3; Just its wall thickness is carried out shaping; At this moment also just play shaping effect that its annular end face flattened because the downward thrust of upper punch 6 is very big this moment, and III stage shaping has also been played certain stable curing effect to I, the shaping in II stage.
