Abstract

The utility model discloses a compound die for trimming and punching. The compound die comprises an upper die plate and a lower die plate, wherein an upper die handle is fixedly arranged on the upper die plate, a guide pillar and a guide sleeve which are in sliding fit are fixed between the upper die plate and the lower die plate, the lower end surface of the upper die plate is fixedly provided with a convex die base plate and a convex die fixing plate in sequence; a punching convex die and a trimming concave die are fixedly arranged at the center and the edge of the bottom of the convex die fixing plate respectively; a concave die base plate and a concave die fixing plate are fixed on the upper end surface of the lower die plate, a trimming convex die is fixedly arranged in the concave die fixing plate, a step is arranged in the trimming convex die, a punching concave die is fixedly arranged on the step of the trimming concave die, and a flanging is arranged on the lower end of the punching concave die. In the utility model, punching and trimming are completed in one set of die, the production line is shortened, the labor intensity is reduced, the production efficiency is improved, and the production cost is lowered.

Description

The edge-cutting and hole-punching composite die
Technical field
The utility model relates to side cut, punching die, specifically belongs to the edge-cutting and hole-punching composite die of carrying roller cylinder.
Background technology
For the needs carrying roller cylinder workpiece with punching of cutting edge, generally need earlier part to be cut edge on bead cutter through three process; To its punching, be placed on shaping in the trimmer at last then, eliminate the influence that side cut and punching cause part; Can not only need three process like this, and need a lot of equipment, cause the production line length; Labour intensity is big, and productivity ratio is low high with production cost.In order to solve the problems of the technologies described above, the someone designs the one step completed mould of punching, side cut, shaping, but structural design is unreasonable, causes the working (machining) efficiency of part bad, and working (machining) efficiency is low.
The utility model content
The purpose of the utility model provides a kind of edge-cutting and hole-punching composite die, and punching is accomplished processing with cutting edge at a mold, and production line shortens, and labour intensity reduces, and production efficiency improves and production cost reduces.
The technical scheme that the utility model adopts is following:
The edge-cutting and hole-punching composite die includes cope match-plate pattern, lower bolster, is installed with die shank on the cope match-plate pattern; Be fixed with the guide pillar, the guide pin bushing that are slidingly matched each other between cope match-plate pattern and the lower bolster respectively; Be installed with convex mould pad, punch retainer on the lower surface of cope match-plate pattern successively, center, punch retainer below, edge are installed with piercing punch, trim die respectively, are fixed with die backing plate, die block on the lower bolster upper surface; Be installed with the side cut punch in the die block; Be provided with step in the side cut punch, be installed with punching concave die on the step of trim die, the lower end of punching concave die has flange; The die cavity of described piercing punch and punching concave die is complementary, and the die cavity of side cut punch and trim die is complementary; Be provided with cavity in the described convex mould pad; Be provided with in the cavity and re-pack; The top pressure that re-packs is equipped with the push rod that passes die shank; Press on the edge of cylindrical work pieces to be equipped with the dnockout cover, the dnockout cover and re-pack between be equipped with the bar of beating that passes convex mould pad, punch retainer, described side cut punch is provided with stripper outward; Described piercing punch below is provided with push rod, and push rod is set with spring outward, and the spring upper end is pressed on the lower surface of piercing punch, and the lower end of spring is pressed on the upper surface of die backing plate.
Be provided with ball between described guide pillar and the guide pin bushing.
Have the step of mutual coupling between described trim die inwall, the dnockout cover outer wall.
The utility model utilizes the die cavity of piercing punch and punching concave die to be complementary carrying roller cylinder is carried out punching; The die cavity of side cut punch and the trim die carrying roller cylinder that is complementary is cut edge; Punching is accomplished processing with cutting edge at a mold; Production line shortens, and labour intensity reduces, and production efficiency improves and production cost reduces.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Referring to accompanying drawing, the edge-cutting and hole-punching composite die includes cope match-plate pattern 1, lower bolster 2; Be installed with die shank 3 on the cope match-plate pattern 1; Be fixed with the guide pillar 4, the guide pin bushing 5 that are slidingly matched each other between cope match-plate pattern and the lower bolster respectively, be provided with ball 6 between guide pillar and the guide pin bushing, be installed with convex mould pad 7, punch retainer 8 on the lower surface of cope match-plate pattern 1 successively; Center, punch retainer 8 below, edge are installed with piercing punch 9, trim die 10 respectively; Be fixed with die backing plate 11, die block 12 on lower bolster 2 upper surfaces, be installed with side cut punch 13 in the die block 12, be provided with step 14 in the side cut punch 13; Be installed with punching concave die 15 on the step of trim die; The lower end of punching concave die 15 has flange 16, and the die cavity of piercing punch and punching concave die is complementary, and the die cavity of side cut punch and trim die is complementary; Be provided with cavity in the convex mould pad 7; Be provided with in the cavity and re-pack 17; The 17 tops pressure that re-packs is equipped with the push rod 18 that passes die shank 3, presses on the edge of cylindrical work pieces 19 to be equipped with dnockout cover 20, has the step of mutual coupling between trim die inwall, the dnockout cover outer wall; Dnockout cover 20 and re-packing be equipped with between 17 pass convex mould pad, punch retainer make bar 21, the side cut punch is provided with stripper 22 outward; The piercing punch below is provided with push rod 23, and push rod is set with spring 24 outward, and spring 24 upper ends are pressed on the lower surface of piercing punch, and the lower end of spring 24 is pressed on the upper surface of die backing plate.
