Like Fig. 9, Figure 10, shown in Figure 11, the said punch 35 that presses adopts the solid punch of four nuts that press simultaneously, and the punch afterbody is a rectangle.The end circular groove mouth that presses has 45 ° of chamferings, the punch 35 that presses be shorter in length than piercing punch length all on the progressive stamping mould, when mould was closed fully, the punch end face that presses contacted with the strip face.
With U type spare is the course of work that example specifies punching press assembling composite die to the production to row's a pair of workpiece among row's stock layout (shown in figure 16) directly:
The utility model punching press assembling composite die has seven work stations and two idle stations; In punching course, strip through each station of mould, is realized punching press successively continuously, the assembling that presses, excision waste material and blank-forming;
At first strip gets into first station of punching press assembling composite die under the guiding of stock guide 23---towards locating hole station 11; After punching press assembling composite die is accomplished a punching press; At this station, the edge of strip is rushed out two locating holes 40 along diagonal, in each station processing afterwards; Locating hole 40 cooperates alignment pin 33 to do accurate location for strip; Before punching press was next time arrived, strip was sent to a step pitch forward, get into punching press assembling composite die second station---first towards pilot hole station 12; After this station stamping assembling composite die is accomplished a punching press, row and respectively go out a pilot hole 41 on the straight-arm of row U type spare down on directly to row's stock layout respectively; Before punching press is next time arrived; Strip is sent to a step pitch forward; Get into punching press assembling composite die the 3rd station---second towards pilot hole station 13, after this station stamping assembling composite die is accomplished a punching press, row and respectively go out a pilot hole 42 on another straight-arm of row U type spare down on directly to row's stock layout respectively; The aperture size of pilot hole 41 and pilot hole 42 has certain requirement, by 0～+ the tolerance dimension punching processing of 0.075mm; For increasing the rigidity of mould, behind pilot hole station 13, increased by one first idle station 14 second, strip is not processed strip during the punching press of punching press assembling composite die through first idle station 14; Before punching press was next time arrived, strip was sent to a step pitch forward, get into punching press assembling composite die the 5th station---assembly station 15 presses; When the punching press of this station stamping assembling composite die, four self-clinching nuts 39 being pressed simultaneously is assemblied on pilot hole 41 and the pilot hole 42, and press 45 ° of chamferings of circular groove mouth of punch 35 ends that when pressing contact with self-clinching nut 39 earlier, and it is accurately located once more; Along with the punch that presses presses down, under the support on the assembling die plane that presses, self-clinching nut 39 lower ends deform and are riveted on the U type spare; Shown in figure 15, the self-clinching nut 39 that this station uses adopts bar gate type feed mechanism automatic feed, and existing function with the action specification feed mechanism of delivery sheet 28 in the bar gate type feed mechanism feeding process (is installed in the both sides of die holder because of the feed mechanism symmetry; The action of location-plate 27 action total and delivery sheet 28 is synchronous but in the opposite direction, repeats no more here), magazine 29 has four vertical through holes; The diameter in hole is used to store self-clinching nut greater than self-clinching nut 39 external diameters, and magazine 29 is parallel to the strip feeding direction and is installed on the outer die shoe of assembling die module; It highly is the groove that 4/3 multiplication of voltage riveting nut height, width are slightly larger than delivery sheet 28 width that the lower end has, and forms discharging opening, and delivery sheet passes through under groove; During die opening state; Delivery sheet is positioned at the below of groove, has stopped the whereabouts of self-clinching nut, when patrix presses down; Pressure head 20 forces rocking bar 21 to rotate around bearing pin 22; Rocking bar 21 drives the delivery sheet recession, and delivery sheet 28 is extracted out from magazine 29 discharging openings gradually, and self-clinching nut 39 falls from magazine 29 on four self-clinching nut to backing plates 30; When patrix is up; Effect lower push rod 24 at spring 26 promotes rocking bar 21 revolutions, and rocking bar 21 drives delivery sheet 28 translation forward, and delivery sheet 28 passes magazine 29 discharging openings; Four self-clinching nuts 39 that four V-type faces of delivery sheet 28 end faces promote to drop down onto on the backing plate 30 (upper surface of backing plate 30 is concordant with the upper surface of blank) move forward; Delivery sheet 28 is pushed into the pilot hole top of blank with four self-clinching nuts 39, clamps the spiral shell that presses with location-plate 27 back of meeting, utilize delivery sheet 28 V-type face and location-plate 27 the ladder end face with four self-clinching nuts 39 be positioned at pilot hole 41 and pilot hole 42 on the strip directly over; Before punching press is next time arrived; Strip is sent to a step pitch forward; Get into the 6th station of punching press assembling composite die---excision scrap (bridge) waste material station 16, the scrap (bridge) waste material 43 of self-clinching nut both sides between the stamping-out workpiece, the self-clinching nut that is riveted on when avoiding blanking on U type spare two arms produces interference to blanking punch 37; Excision is straight to after arranging the scrap (bridge) waste material between the two U type spares, blanking punch structure such as Figure 12, Figure 13, shown in Figure 14; Before punching press was next time arrived, strip was sent to a step pitch forward, got into the 7th station---the first blanking station 17 of punching press assembling composite die; After this station stamping assembling composite die is accomplished a punching press, blanking punch 37 will directly fall following row's workpiece 44 of arranging U type spare, for increasing the rigidity of mould; Be convenient to the installation of punch; Straight two U type spares to row are placed on blanking on two stations respectively, and between two blanking stations, are provided with an idle station, the 8th station---second idle station 18 of punching press assembling composite die; Strip is not processed strip during the punching press of punching press assembling composite die through second idle station 18; Before punching press is next time arrived; Strip is sent to a step pitch forward; Get into the 9th station---the second blanking station 19 that composite die is assembled in punching press, after this station stamping assembling composite die is accomplished a punching press, blanking punch 38 will directly fall the row's of going up workpiece 45 of arranging U type spare; So, strip through each station of punching press assembling composite die, is realized the shaping of workpiece successively.
As stated, the instance of the utility model is specified, but as long as do not break away from the innovative point and the effect of the utility model in fact a variety of variations can be arranged, this will be readily apparent to persons skilled in the art.Therefore, such variation also all is included within the protection domain of the utility model.
