There is a movable beating plate with a push rod embedded in it; the upper die base is embedded with a guide sleeve and the guide post of the lower die base is in clearance fit; the punch for punching round holes is provided with an upper backing plate and a punch fixing plate, and embedded in the push plate; the convex and concave molds are fixed by the convex and concave mold fixing plate and the punch fixing plate; the concave mold, the lower fixing plate and the lower backing plate are fixed on the lower mold base by bolts. The lower convex and concave dies are fixed by the lower fixing plate and the lower backing plate, and pass through the center hole of the blank holder.

Further, the mold adopts a positive composite mold.

Further, the mold adopts an intermediate guide post with good guiding precision to guide the mold base.

Further, the upper backing plate, the punch fixing plate and the punch and concave mold fixing plate of the mold are fixed on the upper mold base by bolts.

Further, the lower convex and concave molds of the mold pass through the blank holder and are fixed by the lower fixing plate and the lower backing plate.

Further, the mold discharge guide plate and the die are fixed by bolts, and the die, the lower fixing plate and the lower backing plate are fixed on the lower die base by bolts.

Further, the mold unloading plate is integrated with the material guide plate, and the material guide pin is used to control the feeding of the sheet material, and it is compressed by the automatic feeding mechanism.

Further, the mold adopts a fixed stopper pin to control the distance of the strip material entering the mold.

The beneficial effects of the technical solution of the utility model are: only one set of molds is needed to realize the multi-process compounding of blanking, bending and punching, reducing process equipment, improving production efficiency, and meeting the requirements of high precision, high benefit and low cost.

detailed description

The preferred implementation cases of the utility model are described in conjunction with the accompanying drawings, so that the advantages of the utility model are easier to understand.

A kind of stamping compound die, comprises upper mold base 14, lower mold base 1, press-in type die handle 18, punching round hole punch 20, convex and concave die 16, die 7 and lower convex and concave die 25; Said press-in type die handle 18 The die handle type is type A, which is installed at the center of the upper die base 14, and a movable beating plate 19 with a push rod 21 is embedded in it; Column 2 clearance fit; the punch 20 for punching round holes is fixed on the upper backing plate 13 above it through the punch fixing plate 12, and embedded in the hole of the push plate 23; the punch and die 16 are fixed on the On the punch fixing plate 12; the die 7, the lower fixing plate 6 and the lower backing plate 5 are fixed on the lower mold base 1 by bolts. The lower convex and concave dies 25 are fixed by the lower fixing plate 6 and the lower backing plate 5, and pass through the central hole of the blank holder 26.

The upper die base 14, the upper backing plate 13, the punch fixing plate 12 and the punch and concave die fixing plate 11 are sequentially connected from top to bottom, and the cylindrical pin 22 realizes a guiding effect on it.

The die 7 and the discharge guide plate 9 are fixed by bolts.

The lower mold base 1, the lower backing plate 5, the lower fixing plate 6 and the die 7 are connected sequentially from bottom to top by bolts.

The pop-up device 28 is fixed on the lower mold base 1 by bolts.

The working mode of the mold described in the utility model: the press slider pushes the upper mold base 14 to move downward through the mold handle 18, and the convex and concave molds 16 first contact the strip blank placed between the discharge guide plate 9 and the concave mold 7, Continue to move forward to complete the blanking process; the upper mold base 14 drives the convex and concave mold 16 to continue downward, the push plate 23 and the lower convex and concave mold 25 perform intermediate bending on the blank, and the convex and concave mold 16 and the blank holder 26 press the blank to bend both ends ; The upper die base 14 continues to descend, and the round hole punch 20 contacts the blank for punching. When the mold is opened on the return trip, the slider of the press drives the upper mold base 14 to move upward, and the convex and concave mold 16 first moves upward to leave the workpiece. Break away from the male and female dies 16 and the push plate 23.

The beneficial effects of the utility model are: in the technical scheme, the convex and concave dies and the concave die can realize the blanking process; The mold can realize the punching process. The utility model only needs one set of moulds, which can realize the multi-process processing of blanking, bending and punching, can greatly improve the production efficiency, and meet the requirements of high precision, high benefit and low cost.
