Abstract
The utility model discloses a lift coupler forging die comprising an upper die and a lower die which are provided with cavities matched with a lift transmission shaft coupler. The upper die is provided with an annular boss on the outer side of an edge opening of the die cavity thereof; the lower die is provided with an annular recess on the outer side of an edge opening of the die cavity thereof; the inner wall of the annular boss is provided with an upper guide surface and the inner wall of the annular recess is provided with a lower guide surface matched with the upper guide surface; and a disposable lubricating film matched with the outer surface of the coupler is disposed in the edge opening of the lower die. The lower guide surface on the outer side of the edge opening of the cavity of the lower die can sufficiently bear the lateral deflection force from the downward pressing of the upper die, so that the consistency of center lines of the upper die and the lower die can be guaranteed during press fit of the upper die and the lower die and the quality of forging stocks obtained through pressing can be reliably guaranteed. The disposable lubricating film is disposed in the edge opening of the cavity of the lower die, so that a wheel center forging stock can be easily separated from the lower die.
Description
Technical field
The utility model relates to a kind of forging and stamping parts, is specifically related to a kind of lift shaft coupling forging die.
Background technology
At the press for forging and pressing lift shaft coupling forging die, when weighing the axle core blank compacting axle core forging base of more than 600 kilogram, guarantee that upper and lower mould center line is unanimously key point.Three leads of generally need to burn-oning on counterdie periphery, when compacting, patrix is along lead pressing, in pressing process, blank can not remain that in deformation process vertical force moves conventionally downwards, will inevitably produce the side force that upper and lower mould is moved, because most of power is all delivered on lead by patrix, therefore, when lead holds while can't stand this side force, will be crooked, thereby cause upper and lower mould to lose guiding restriction, so just cannot guarantee the correct centering of upper and lower mould, upper and lower mould center line is inconsistent.Like this, the quality of the forging stock that obtains of compacting just can not be guaranteed, thereby causes waste product, and counterdie is repeatedly being used rear surface can become coarse in addition, so both can affect by any surface finish of forging and stamping workpiece excessively, and the while is also unfavorable for the distortion of metal.
Utility model content
The purpose of this utility model is to overcome the defect existing in prior art, provides a kind of and can guarantee that upper and lower mould center line is unanimously for the forging die of lift shaft coupling.
For achieving the above object, the technical solution of the utility model is a kind of lift shaft coupling forging die of design, described forging die comprises: offer respectively the upper die and lower die that match with lift power transmission shaft shaft coupling, it is characterized in that, described patrix has annular boss in the arranged outside of its die cavity bead, described counterdie has ring-shaped depression in the arranged outside of its die cavity bead, on the inwall of described annular boss, be provided with spigot surface, on the inwall of described ring-shaped depression, be provided with described on the suitable lower spigot surface of spigot surface; In the bead of described counterdie, be provided with and the suitable disposable lubricating film of shaft coupling outer surface.
For the ease of coordinating of patrix and drift, preferred technical scheme is, is provided with the upper impression suitable with shaft coupling first half profile in described patrix, and described upper impression communicates with bore of the punch.
The location that coordinates for the ease of counterdie with patrix, further preferably technical scheme is, is provided with and the suitable lower impressions of shaft coupling Lower Half profile in described counterdie, in described lower impressions bottom, is provided with the positioning boss matching with described bore of the punch.
For the ease of the mobile raising of metal, forged and pressed the surface quality of workpiece, further preferred technical scheme also has, and described lubricating film is tetrafluoro vinyon, and the thickness of described lubricating film is 0.1 ~ 0.2mm.
Advantage of the present utility model and beneficial effect are: because the lower spigot surface outside the die cavity bead of counterdie is enough to bear the biasing force that presses down the side direction in process from patrix, thereby when upper and lower mold pressing is closed, can guarantee that upper and lower mould center line is consistent, make the quality of suppressing the forging stock obtaining obtain Reliable guarantee.In the bead of die cavity counterdie, be provided with in addition disposable lubricating film, separated for the ease of being easy between wheel core forged blank and counterdie, frictional resistance in the time of can reducing to forge and press between wheel core forged blank and counterdie sidewall simultaneously, thereby can reduce the driving power of stamping machine, also can reduce punching press noise simultaneously.

The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is further described.Following examples are only for the technical solution of the utility model is more clearly described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, 2, the utility model is a kind of lift shaft coupling forging die, described forging die comprises: offer respectively the patrix 1 and the counterdie 2 that match with lift power transmission shaft shaft coupling, patrix 1 has annular boss 3 in the arranged outside of its die cavity bead, counterdie 2 has ring-shaped depression 4 in the arranged outside of its die cavity bead, on the inwall of annular boss 3, be provided with spigot surface 5, on the inwall of ring-shaped depression 4, be provided with the lower spigot surface 6 suitable with upper spigot surface 5; In the bead of counterdie 2, be provided with and the suitable disposable lubricating film 7 of shaft coupling outer surface.
In the utility model, for the ease of the coordinating of patrix 1 and drift, preferred embodiment is, is provided with the upper impression 9 suitable with shaft coupling 8 first half profiles in patrix 1, and upper impression 9 communicates with bore of the punch 10.
In the utility model for the ease of counterdie 2 location that coordinates with patrix 1, further preferred embodiment is, in counterdie 2, be provided with and the suitable lower impressions 11 of shaft coupling 8 Lower Half profile, in the bottom of lower impressions 11, be provided with the positioning boss 12 matching with bore of the punch 10.
In the utility model, for the ease of the mobile raising of metal, forged and pressed the surface quality of workpiece, further preferred embodiment also has, and lubricating film 7 is tetrafluoro vinyon, and the thickness of lubricating film 7 is 0.1 ~ 0.2mm.
