The combined type starlike sleeve pre-forging die comprises an upper die body and a lower die body, the upper die body is composed of an upper punch, an upper die plate, an upper padding plate, guide sleeves, an upper female die and an upper female die strengthening ring, wherein the upper punch is arranged in the upper padding plate, the guide sleeves are in interference fit in the upper padding plate, the upper die plate is connected with the upper padding plate through screws, the upper female die is in interference fit in the an upper female die strengthening ring, and the upper female die strengthening ring is fixedly connected to the upper padding plate through screws; the lower die body is composed of guide columns, a lower female die, a lower female die strengthening ring, a lower padding plate, a lower punch, a lower die plate and an ejecting rod, wherein the ejecting rod is arranged in the lower die plate, the lower punch is arranged in the lower padding plate, the lower padding plate is connected with the lower die plate through screws, the lower female die is in interference fit in the lower female die strengthening ring, the lower female die strengthening ring is connected onto the lower padding plate through screws, and the guide columns are in interference fit in the lower die plate. By the adoption of the technical scheme, the combined type starlike sleeve pre-forging die has the advantages that the structure is simple, the replacement cost can be reduced effectively, and the replacement is convenient.
Description
Technical field
The present invention relates to a kind of Combined star cover Preform Die, belong to forge die field, be mainly used in inner race blocker forging.
Background technology
Inner race is an important part in automobile gimbal, and inner race often adopts one to be that blocking adds finish forge two one-step forming, and two is closed die forging one-step shapings.Closed die forging one-step shaping mould is complicated, and briquetting pressure is large, and formed precision is relatively somewhat low.Adopting blocking to add finish forge two one-step forming precision high, though the long-acting rate of molding cycle is low, but still is the forming method of main employing in the market.In blocker forging, the design of mould often adopts monolithic mold, and use the stressed bottom greatly of lower cavity die in middle discovery to occur subsiding or crackle, the replacement cost of mould is high.
Summary of the invention
For above-mentioned prior art Problems existing, in order to lower the replacement cost of mould, the invention provides the simple combined type Preform Die of a kind of structure.
Technical scheme of the present invention is: a kind of Combined star cover Preform Die, comprise patrix and counterdie, patrix is made up of upper punch, cope match-plate pattern, upper padding plate, guide pin bushing, upper cavity die, upper cavity die stiffening ring, upper punch is placed in upper padding plate, guide pin bushing interference fit is in upper padding plate, cope match-plate pattern and upper padding plate screw attachment, upper cavity die interference fit is in upper cavity die stiffening ring, and upper cavity die stiffening ring is fixed on upper padding plate by screw attachment; Counterdie is made up of guide pillar, lower cavity die, lower cavity die stiffening ring, lower bolster, low punch, lower bolster, push rod, push rod is placed in lower bolster, low punch is placed in lower bolster, lower bolster and lower bolster screw attachment, lower cavity die interference fit is in lower cavity die stiffening ring, lower cavity die stiffening ring is by screw attachment on lower bolster, and guide pillar interference fit is in lower bolster.
There is a circle boss described upper cavity die stiffening ring lower surface, and there is a circle groove lower cavity die stiffening ring upper surface, and its boss and groove fit can play the role of positioning.
Combined star cover Preform Die structure described in the present invention is simple, and can effectively reduce replacement cost, it is convenient to change.
Accompanying drawing explanation
Figure is Combined star of the present invention cover Preform Die structural representation.
1. upper punch, 2. cope match-plate pattern, 3. upper padding plate, 4. guide pin bushing, 5. guide pillar, 6. lower cavity die in figure, 7. lower cavity die stiffening ring, 8. lower bolster, 9. lower bolster, 10. push rod, 11. upper cavity dies, 12. upper cavity die stiffening rings, 13. low punches.
Detailed description of the invention
As shown in the figure, described Combined star cover Preform Die, comprise patrix and counterdie, patrix is made up of upper punch 1, cope match-plate pattern 2, upper padding plate 3, guide pin bushing 4, upper cavity die 11, upper cavity die stiffening ring 12, upper punch 1 is placed in upper padding plate 3, guide pin bushing 4 interference fit in upper padding plate 3, cope match-plate pattern 2 and upper padding plate 3 screw attachment, upper cavity die 11 interference fit is in upper cavity die stiffening ring 12, and upper cavity die stiffening ring 12 is fixed on upper padding plate 3 by screw attachment; Counterdie is made up of guide pillar 5, lower cavity die 6, lower cavity die stiffening ring 7, lower bolster 9, low punch 13, lower bolster 7, push rod 10, push rod 10 is placed in lower bolster 8, low punch 13 is placed in lower bolster 9, lower bolster 9 and lower bolster 8 screw attachment, lower cavity die 6 interference fit is in lower cavity die stiffening ring 7, lower cavity die stiffening ring 7 is by screw attachment on lower bolster 9, and guide pillar 5 interference fit is in lower bolster 8.
There is a circle boss described upper cavity die stiffening ring 12 lower surface, and there is a circle groove lower cavity die stiffening ring 7 upper surface, and its boss and groove fit can play the role of positioning.
In described Combined star cover Preform Die, in advance the cylindrical blank being preheating to uniform temperature is positioned in lower cavity die 6, patrix is fixed on forcing press and moves downward along with forcing press upper base plate is descending, the guide pin bushing 4 of patrix first contacts with the guide pillar 5 of counterdie and coordinates, upper cavity die 11 and upper punch 1 contact with blank and apply pressure to blank and make it be out of shape subsequently, and progressively fill the die cavity of full upper cavity die 11 and lower cavity die 6, after extruding, patrix starts rollback, push rod 10 in counterdie moves upward under press hydraulic cylinder drives, push rod 10 promotes low punch 13 and preformed inner race is ejected a segment distance from lower cavity die 6, pliers is utilized to be taken out from lower cavity die 6 by pre-forging.
