For realizing that the technical scheme that the purpose of this utility model adopts is:
A kind of automobile absorber spring seat of honour rounding processing unit (plant), it is characterized in that, comprise upper die unit and lower die unit, described upper die unit comprises cope match-plate pattern, fixed head, die shank, the center knockout rod, die, described fixed head one side is fixedly connected with described cope match-plate pattern, described fixed head another side is fixedly connected with described die, be provided with the rounding working groove corresponding with the rounded portion of processing rear workpiece on the described die, described cope match-plate pattern is connected with the power set of pressing equipment by described die shank, and the center of described die shank is equipped with the described center knockout rod relative with rounding working groove top; Described lower die unit comprises lower bolster, backing plate, punch, stripper plate, elastomer, described backing plate is fixedly connected with described lower bolster, the position corresponding with the rounding working groove on the described die, described backing plate center is fixed with described punch, described stripper plate is positioned at the periphery of described punch, and be connected with described backing plate by connecting pin, the position corresponding with punch is provided with the workpiece to be processed locating slot on the described stripper plate, the top of described punch contacts with the inside top face of workpiece to be processed, between described stripper plate and the described backing plate described elastomer is installed; Described cope match-plate pattern is slidingly connected by guide pin bushing and the guide pillar that matches with described lower bolster.
Described elastomer is elastomeric material.
Compared with prior art, the beneficial effects of the utility model are:
1, in the rounding processing unit (plant) of the automobile absorber spring of the present utility model seat of honour elastomer is installed, in punching course, has pooling feature, can have protective effect to mould, improved service life.Also as the power of stripper plate, simple in structure, easy and simple to handle simultaneously.And by the design of center knockout rod and stripper plate, the demoulding is easier, has improved production efficiency.
2, in the rounding processing unit (plant) of the automobile absorber spring of the present utility model seat of honour, the top of punch contacts with the top center of workpiece to be processed, has positioning action, and machining accuracy is higher.
Description of drawings
Figure 1 shows that the schematic diagram of the utility model automobile absorber spring seat of honour rounding processing unit (plant) upper die unit and lower die unit separated position;
Figure 2 shows that the schematic diagram of the utility model automobile absorber spring seat of honour rounding processing unit (plant) punching press state.
Among the figure: 1. guide pin bushing, 2. cope match-plate pattern, 3. fixed head, 4. die shank, 5. center knockout rod, 6. guide pillar, 7. alignment pin, 8. die, 9. rounding working groove, 10. punch, 11. stripper plates, 12. elastomers, 13. backing plates, 14. lower bolsters, 15. workpieces to be processed.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
The schematic diagram of the utility model automobile absorber spring seat of honour rounding processing unit (plant) comprises upper die unit and lower die unit as shown in Figure 1 and Figure 2.Described upper die unit comprises cope match-plate pattern 2, fixed head 3, die shank 4, center knockout rod 5, die 8, described fixed head 3 one sides are fixedly connected with described cope match-plate pattern 2, described fixed head 3 another sides are fixedly connected with described die 8, be provided with the rounding working groove 9 corresponding with the round cap portion of processing rear workpiece on the described die 8, described cope match-plate pattern 2 is connected with the power set of pressing equipment by described die shank 4, and the center of described die shank 4 is equipped with the described center knockout rod 5 relative with rounding working groove top.Described lower die unit comprises lower bolster 14, backing plate 13, punch 10, stripper plate 11, elastomer 12, and described elastomer is elastomeric material.Described backing plate 13 is fixedly connected with described lower bolster 14, rounding working groove 9 corresponding positions on described backing plate 13 centers and the described die are fixed with described punch 10, described stripper plate 11 is positioned at the periphery of described punch 10, and be connected with described backing plate 13 by connecting pin 7, the position corresponding with punch is provided with the workpiece to be processed locating slot on the described stripper plate 11, the top of described punch 10 contacts with the inside top face of workpiece to be processed 15, and described elastomer 12 is installed between described stripper plate 11 and the described backing plate 13.Described cope match-plate pattern 2 is slidingly connected by guide pin bushing 1 and the guide pillar 6 that matches with described lower bolster 14.
During use, workpiece to be processed 15 is placed in the workpiece to be processed locating slot on the stripper plate.Power set drive die shank, cope match-plate pattern, fixed head, die and move down, and the circular working groove on the die cooperates with punch and workpiece to be processed 15 is carried out rounding processes, and the while elastomer is compressed.Power set drive punch and rise, and elastomer drives stripper plate by the elastic force effect and rises, and the workpiece after the processing is broken away from punch, and simultaneously, the center knockout rod impacts the top of circular working groove, make workpiece and die disengaging after the processing, finish the processing of a workpiece.
The above only is preferred embodiment of the present utility model; should be noted that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
