Detailed description of the invention
For describing technology contents of the present utility model, structural feature, the effect that realizes in detail, accompanying drawing is coordinated to be explained in detail below in conjunction with embodiment.
As shown in Figures 1 to 4, the utility model cold punching die 100 comprises inner stripper 1, cope match-plate pattern 2, lower bolster 3, backing plate 4, loading plate 5, liftout plate 6, ejects pin 7, flexible member 8 and pressing plate 9, and described flexible member 8 is Compress Spring.Described lower bolster 3 is fixed on described loading plate 5, described cope match-plate pattern 2 has hollow area 21, described inner stripper 1 is positioned at described hollow area 21 and with described lower bolster 3 product clamping 200 with the below making the clout of product 200 reach described cope match-plate pattern 2, described cope match-plate pattern 2 is fixed with described backing plate 4, described inner stripper 1 hang on described backing plate 4, described backing plate 4 is fixed with described pressing plate 9, described liftout plate 6 is placed in above described backing plate 4, and described flexible member 8 is arranged between described pressing plate 9 and described liftout plate 6; The upper surface of described pressing plate 9 lower surface and described liftout plate 6 is provided with locating hole 61, and the end of described flexible member 8 is placed in described locating hole 61.Described locating hole 61 can entangle described flexible member 8, prevents flexible member 8 to be shifted.The described pin 7 that ejects slidably passes through described backing plate 4 and contacts at described liftout plate 6 and described inner stripper 1.
Again as shown in Figure 1 and Figure 2, the both sides between described pressing plate 9 and described backing plate 4 are fixed with back-up block 91, form accommodating cavity 92 described in two between back-up block 91, described pressing plate 9 and described backing plate 4, and described liftout plate 6 and flexible member 8 are arranged in described accommodating cavity 92.Arrange described back-up block 91, described backing plate 4 can be made on the one hand to be interconnected and fixed with described pressing plate 9, and another conveniently can form accommodating cavity 92, thus realizes holding described liftout plate 6 and flexible member 8.
Refer to Fig. 3 again, described loading plate 5 is provided with lead 51, and described cope match-plate pattern 2 is provided with pilot hole 22, and described lead inserts in described pilot hole 22.Arrange described lead 51, the effect can getting up guide when described cope match-plate pattern 2 is descending, ensures the accurate of punching press.
Refer to Fig. 3 and Fig. 4 again, be provided with between described inner stripper 1 with described backing plate 4 and be connected pin 12, the surface of described backing plate 4 is provided with through hole 41, described through hole 41 internal fixtion has the sliding sleeve 42 running through described backing plate 4, one end of described connection pin 12 and described inner stripper 1 are fixed, and the other end of described connection pin 12 slidably passes through described sliding sleeve 42 and ailhead contacts at the surface of the sliding sleeve 42 in described backing plate 4 through hole 41.By arranging described connection pin 12, when the ailhead of described connection pin 12 and described backing plate 4 are conflicted, described inner stripper 1 can only rise and can not move down by relatively described backing plate 4 by relatively described backing plate 4, thus cut in the process of clout at described cope match-plate pattern 2, the pressure holding all the time of described inner stripper 1 is on product 200, and when described cope match-plate pattern 2 rises, described inner stripper 1 can move relative to described cope match-plate pattern 2 and stretch out described cope match-plate pattern 2.
Comprehensively above-mentioned, below the course of work of the utility model cold punching die 100 is described in detail, as follows:
First, half-finished product 200 is positioned on lower bolster 3, described cope match-plate pattern 2 and inner stripper 1 is driven to move down by described pressing plate 9 again, make described inner stripper 1 and described lower bolster 3 matched moulds, thus pressure holding half becomes the product 200 of mouth, when described pressing plate 9 continues to move down again, due to the effect of described connection pin 12, described inner stripper 1 is held in described lower bolster 3 plywood, and described backing plate 4 and described lower bolster 3 continue to move down, at this moment, described liftout plate 6 supported by the described pin 7 that ejects, thus compress described flexible member 8, described flexible member 8 provides the pressure compressing described inner stripper 1 to make described inner stripper 1 pressure holding product 200 to the described pin 7 that ejects, meanwhile, product 200 clout of described lower bolster 3 to described inner stripper 1 periphery carries out punching press excision.After punching press completes, described pressing plate 9 drives described backing plate 4 and cope match-plate pattern 2 to move up, at this moment, due to the elastic-restoring force of flexible member 8, described inner stripper 1 is made to keep fitting on described lower bolster 3, namely described inner stripper 1 relatively stretches out described cope match-plate pattern 2, at this moment, be equivalent to make product 200 depart from described hollow area 21, when after the segment distance that continues to move up, stretch out after described cope match-plate pattern 2 completely until the face that compresses of described inner stripper 1, product 200 can depart from described hollow area 21 completely and successfully take out.
Compared with prior art, because the utility model by arranging liftout plate 6 on described backing plate 4, between described liftout plate 6 and described pressing plate 9, flexible member 8 is set, and arrange one and eject pin 7, eject pin 7 described in making slide through described backing plate 4 and contact at described liftout plate 6 and described inner stripper 1, thus the elastic acting force of described flexible member 8 is utilized when punching press, described inner stripper 1 is pressed on product 200, after punching press completes, utilize the elastic-restoring force of described flexible member 8, described inner stripper is ejected described cope match-plate pattern 2, and then make product 200 depart from described cope match-plate pattern 2, cannot take out in the hollow area 21 preventing product 200 after punching press to be fastened in described cope match-plate pattern 2, therefore, the utility model has automatic demoulding, facilitates product 200 to take out, the advantage of effectively enhancing productivity.
Above disclosedly be only preferred embodiments of the present utility model, certainly can not limit the interest field of the utility model with this, therefore according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
