The specific embodiment
The utility model provides a kind of diel and stamping parts that is used for punch rivet, for purpose, technical scheme and the effect that makes the utility model is clearer, clear and definite, below develops simultaneously embodiment to the utility model further explain with reference to accompanying drawing.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
See also Fig. 1, it is used for the structured flowchart of first preferred embodiment of the diel of punch rivet for the utility model.As shown in Figure 1, the diel that is used for punch rivet that the utility model provides comprises that die shoe 11, lower bolster 13 and counterdie go into piece 14.Said lower bolster 13 is gone into piece 14 with counterdie and is arranged on the said die shoe 11, and said counterdie goes into piece 14 and pass said lower bolster 13, extend out to a side of lower bolster 13.In the present embodiment, go into to be provided with in the piece 14 location buoyance lift pin 15 at counterdie, when punching press, rivet 10 passes stamping parts 21 and is placed on the location buoyance lift pin 15 and leads for rivet 10 through this location buoyance lift pin 15.
In this specific embodiment; In said die shoe 11, be provided with elastic component 16, promptly this elastic component 16 runs through die shoe 11, and withstands the pin cap 151 on buoyance lift pin 15 tops, location; Be used for supporting location buoyance lift pin 15; This elastic component 16 makes the end of location buoyance lift pin 15 stretch out counterdie to go into piece 14, when punching press, only need rivet 10 is placed on the location buoyance lift pin 15 before the punching press.In the present embodiment, said elastic component 16 is spring or catapult glue, and the external diameter of said location buoyance lift pin 15 is identical with the external diameter of rivet 10, makes rivet 10 in the process that descends with location buoyance lift pin 15, and rivet 10 can be not crooked.
Please continue to consult Fig. 1; The diel that is used for punch rivet that the utility model provides first preferred embodiment to provide comprises that also upper bolster 17, train wheel bridge 18 and riveted joint are towards 19; Said train wheel bridge 18 dashes 19 with riveted joint and is arranged on the upper bolster 17; And said riveted joint is dashed 19 and is passed train wheel bridge 18, stretches out a side of train wheel bridge 18.When punching press, said riveted joint dash 19 be positioned at location buoyance lift pin 15 directly over.
In order to realize guiding better, an end (promptly locating the end of the buoyance lift pin 15) surface of said location buoyance lift pin 15 is provided with the convexity 152 that is used for correcting rivet 10, and is as depicted in figs. 1 and 2.The rivet hole (not marking among the figure) of said protruding 152 external diameter and rivet 10 is suitable; When punching press, avoid rivet 10 crooked, thereby realize that rivet 10 leads quickly and accurately in the riveted joint process, and after the punching press completion; This convexity 152 also is convenient to rivet 10 taking-ups, and it is fast to make diel take off material.
Please consult Fig. 1 once more; The diel that is used for punch rivet that the utility model provides first preferred embodiment to provide; The bottom surface of said die shoe 11 is provided with set screw 20, and the effect of this set screw 20 is mainly used in fixing and support elastic spare 16, and its another effect is; After set screw 20 screws out from die shoe 11, the location buoyance lift pin 15 of replaceable elastic component 16 and different size.
See also Fig. 3, it is used for the structured flowchart of second preferred embodiment of the diel of punch rivet for the utility model.The diel difference that is used for punch rivet of the diel that is used for punch rivet of this second preferred embodiment and first preferred embodiment only is; Between die shoe 11 and lower bolster 13, be provided with lower bolster 12; In punching course; This lower bolster 12 main cushioning effects that rise avoid damaging owing to the pressure of upper bolster 17 is excessive rivet 10 and stamping parts.In the present embodiment, said elastic component 16 passes die shoe 11 successively and withstands the pin cap 151 on buoyance lift pin 15 tops, location with lower bolster 12, supports location buoyance lift pin 15.
Based on the above-mentioned diel that is used for punch rivet, the utility model also correspondence provides a kind of fixing stamping parts of above-mentioned diel punching press that adopts, and wherein, said stamping parts is backboard or other stamping parts.
The workflow of the diel fixing rivet that is used for punch rivet that the utility model is provided below in conjunction with Fig. 3 is elaborated:
After diel installs, earlier rivet 10 is inserted in the corresponding mounting hole of stamping parts 21, and rivet 10 is placed on the convexity 152 of location buoyance lift pin 15, the convexity 152 of locating on the buoyance lift pin 15 is inserted in accomplishes correcting in the rivet hole of rivet 10; The riveting cap that the upper bolster 17 of punch press control afterwards, train wheel bridge 18 and riveted joint are pushed down rivet 10 towards 19 declines carries out punching press.Diel rivet 10 in punching course moves down with location buoyance lift pin 15; And because the external diameter of rivet 10 is identical with the external diameter of location buoyance lift pin 15; Make in rivet 10 folding processes and avoid rivet 10 crooked, when diel is closed, accomplish punching press, upper bolster 17, train wheel bridge 18 and riveted joint afterwards dashed 19 and moved up; Elastic component 16 utilizes its elastic restoring force that location buoyance lift pin 15 is risen, and can take out stamping parts 21.
In sum; Diel that is used for punch rivet and stamping parts that the utility model provides have adopted at counterdie and have gone into to be provided with in the piece location buoyance lift pin, in said die shoe, are provided with the elastic component that is used to support said location buoyance lift pin; When punching press, pass through location buoyance lift pin correcting rivet; Rivet follows location buoyance lift pin closely and descends and avoid rivet crooked in punching course, has promoted the quality of stamping products, has improved production efficiency greatly.And the utility model diel that is used for punch rivet and the stamping parts that provide, it is simple in structure, easy to operate, practical.
It is understandable that; Concerning those of ordinary skills; Can be equal to replacement or change according to the technical scheme and the utility model design thereof of the utility model, and all these changes or replacement all should belong to the protection domain of the appended claim of the utility model.
