Lower bolster 1 in lower membrane module of the present utility model connects lower bolster 2, lower edge of a knife seat 3, the lower edge of a knife 14 and stripper 5 successively.Lower bolster 1, connection lower bolster 2, lower edge of a knife seat 3 are bolted into an integral body with the lower edge of a knife 14.Stripper 5 in the utility model is realized and being slidably arranged on the lower edge of a knife 14 by spring element, its objective is that the material box blanking part to being placed on stripper 5 all has good pressing effect, so the surface of the work of rushing out is flat being lost relatively, quality is better, is particularly suitable for stamping-out thinner thickness, blanking part that material is softer.Simultaneously the utility model is not in order to hinder the pressing effect of elasticity discharging. on stripper 5, corresponding to installing on blanking die face on the relevant position of fixedly pin stop and guide pin, have counterbore.On the lower edge of a knife 14, lower bolster 2 and lower bolster 1 in this lower membrane module, be equipped with the blanking port corresponding with drift 18 24, described blanking port 24 increases successively; The quantity of blanking port 24 described here is corresponding one by one with the drift 18 in upper die component.As shown in Figure 1.
The utility model is in order to improve tooth shape chain board profile euphotic belt precision, and the lower edge of a knife in the utility model adopts SKH-51 high-speed steel of the prior art, and greatly strengthened the service life of the lower edge of a knife 14.The utility model, for the better tooth shape chain board profile euphotic belt precision that improves, is provided with striker plate 6 on the utility model stripper 5.The utility model is in order to make when upper die component and the lower membrane module matched moulds, and punch press is given the impulsive force of lower membrane module, makes the position of the lower edge of a knife 14 more firm, and the utility model is provided with for the further alignment pin 27 of the fixing lower edge of a knife 14 positions on lower edge of a knife seat 3.As shown in Figure 1.
The precision of the utility model when further improving upper die component and lower membrane module matched moulds, lower membrane module of the present utility model also comprises and penetrates stripper 5 and lower edge of a knife seat 3 is fixed on the little guide pillar 16 on lower bolster 2 simultaneously; On described cope match-plate pattern 11, upper padding plate 19, punch fixing plate 9, upper slitter oralia 8 and the upper edge of a knife 7, be equipped with and connect the through hole that little guide pillar 16 slides.As shown in Figure 2.
Adopt stamping die stamping-out tooth shape chain board of the present utility model, carrier bar two holes and tooth profile complete in a work step, have guaranteed that tooth shape chain board two holes, centre-to-centre spacing and tooth profile have higher positional precision, thereby have guaranteed the even running of silent chain when work.
The course of work of the utility model stamping die is as described below:
Preparation, according to the size of the model of punch press and material, determines the quantity of drift 18 and stamping die is installed; Material is placed on stripper 5 and between striker plate 6.Upper die component is when original state, and the upper rod 20 of beating is pressed downwardly onto extreme lower position by spring girth sheets 12, and now, turn 13 protrudes the upper edge of a knife 7, and drift embeds in turn 13;
Matched moulds starts, press ram in punch press moves downward, punch press drives upper die component to move downward by connecting rod 23, guide pin bushing 25 on cope match-plate pattern 11 and the guide pillar 26 on lower bolster 1 play the effect of guiding, simultaneously little guide pillar 16 slides along through hole on cope match-plate pattern 11, upper padding plate 19, punch fixing plate 9, upper slitter oralia 8 and the upper edge of a knife 7, plays the effect of auxiliary guiding.After upper die component and lower membrane module matched moulds, the upper edge of a knife 7 and stripper 5 carry out stamping-out by material compression, drift 18 and 14 pairs of materials of the lower edge of a knife, during stamping-out, because the impulsive force of punch press makes stripper 5 under the effect of spring element, move downward mobile cushioning certain position, now, the upper rod 20 of beating will move upward, and turn 13 is embedded in the edge of a knife 7, and drift protrudes the upper edge of a knife 7, complete stamping-out, the material after stamping-out covers on drift 18.As shown in Figure 1.
The demoulding starts, press ram in punch press moves upward, punch press drives upper die component to move upward by connecting rod 23, guide pin bushing 25 on cope match-plate pattern 11 and the guide pillar 26 on lower bolster 1 play the effect of guiding, simultaneously little guide pillar 16 slides along through hole on cope match-plate pattern 11, upper padding plate 19, punch fixing plate 9, upper slitter oralia 8 and the upper edge of a knife 7, plays the effect of auxiliary guiding.Upper dozen rod 20 in upper die component need be returned to original state, and the upper rod 20 of beating is pressed downwardly onto extreme lower position by spring girth sheets 12, now, turn 13 protrudes the upper edge of a knife 7, drift embeds in turn 13, and the material covering on drift 18 will, by under turn 13 gears, fall automatically.As shown in Figure 2.
The utility model does not relate to partly all same as the prior art or employing prior aries to be realized.
Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improvement and conversion all should belong to the protection domain of the utility model claims.
