Abstract

The utility model belongs to a cold stamping processing mold, and relates to a composite mold for cutting materials inside and outside, which includes a material cutting structure, an anti-wrinkle structure, a stretching and pressing structure, and a shrinkage and rebounding structure of the remaining material. The two punches and two dies of the material complete the material cutting, the upper part is leveled by an anti-wrinkle monolithic mechanism, and the stretching and pressing are completed by the stretching and pressing punch and die. The utility model is changed from the original processing on two punch presses with two sets of molds to one-time molding parts with one punch press and a set of molds. The size of the outer circle blanking is reduced, the material is saved, and the energy consumption is reduced.

Fig. 1 is structural representation of the present utility model.

Wherein, 1-die shank, 2-blank punch, 3-blank die, 4-piercing punch, 5-punching concave die, 6-stretching die mould die, 7-stretching die mould punch, the smooth material ring of 8-, 9-clout apical ring, 10-upper bolster, 11-die shoe, 12-head part bar, 13-head part plate, 14-the first rubber slab, 15-the first backing plate, 16-adjusting nut, 17-screw rod, 18-top board, 19-the second rubber slab, 20-the second backing plate, 21-first adjust nut, 22-push rod, 23-second and adjust nut, 24-the 3rd rubber slab, 25-the 4th rubber slab, 26-edge mould.

The specific embodiment:

Below by specific embodiment, utility model is described in further details:

Refer to Fig. 1, the structural representation of the inside and outside blank composite die of the utility model, described inside and outside blank composite die comprises that blanking structure, anti-corrugated structures, stretching and pressure-type structure, clout shrink resilient structures, wherein, described blanking structure is made up of blank punch 2, blank die 3, piercing punch 4, punching concave die 5, upper bolster 10, die shoe 11, blank punch 2 and punching concave die 5 are fixed on die shoe 11, and blank die 3 and piercing punch 4 are fixed on upper bolster 10.

Described anti-wrinkling mechanism is made up of smooth material ring 8, screw rod 17, top board 18, the second rubber slab 19, the second backing plate 20, the first adjustment nut 21 and push rod 22, smooth material ring 8 is connected by push rod 22 with top board 18, and top board 18, rubber slab 19, the second backing plate 20 are adjusted nut 21 by screw rod 17 and first and linked together.

Described clout shrinks resilient structures and is made up of head part bar 12, head part plate 13, the first rubber slab 14, the first backing plate 15 and adjusting nut 16, head part bar 12 is through die shoe 11, and head part plate 13, the first rubber slab 14, the first backing plate 15 are fixed on die shoe 11 belows with adjusting nut 16 from top to bottom.

Described stretching and die mould are made up of the die mould die 6 that stretches, stretching die mould punch 7, the 3rd rubber slab 24, the 4th rubber slab 25, edge mould 26, stretching die mould die 6 is socketed in stretching die mould punch 7 outsides, the 3rd rubber slab 24 is set under stretching die mould punch 7, middle arranges the 4th rubber slab 25, and edge mould 26 is below stretching die mould punch 7 inner the 4th rubber slabs 25.

The utility model has been acted on the stamping-out of endoporus mutually by piercing punch 4 and punching concave die 5, acted on mutually the stamping-out of cylindrical by blank punch 2 and blank die 3, the drawing of part and die mould have been coordinated by stretch die mould punch 7 and stretching die mould die 6 and punching concave die 5 cylindricals and edge mould 26.

Part bead face stretches anti-wrinkling and unload clout and shrink rebounding mechanisms by upper and lower two and complete.The 3rd rubber slab 24 and the 4th rubber slab 25 play stretch buffering and rebound effect.

Method while providing the utility model specific works below: tinplate cladding is put on the peaceful material all in one piece ring 8 of blank punch 2, trample clutch for puncher, slider of punch drives die shank 1 to sweep away, a hole gone out by material by piercing punch 4 and die 5, patrix continues descending, stretching die mould punch 7 and edge mould 26 stretch outside iron sheet drawing, walk to after certain size, cut cylindrical punch 2 and cut outer cupping tool 3 interactions and cut cylindrical.At this moment, stretching die mould punch 7 inwardly shrinks cylindrical iron sheet to U-shaped place by cylindrical.Now the peaceful material all in one piece ring 8 of blank punch 2 compresses the rim charge herein and between the two, makes the inside time receiving of iron sheet wrinkle resistant.Clout apical ring 9 is pressed on head part plate 13 to descending compressing push rod 12 tops under the compressing of blank die 3, and now the first rubber slab 14 shrinks.After all punching presses have been moved, when die shank 1 drives blank die 3, stretching die mould punch 7, edge mould 26, the smooth material ring 8 of upper bolster to rise, the second rubber slab 19 is upspring and is promoted die pad 18 top and press ejector beams 22 to eject the step place of material all in one piece ring to blank die 3.When upper modular ring promotes, the first backing plate 15 is also upspring and is boosted head part plate 13 and eject head part bar 12 by clout apical ring 9 jack-up, and clout apical ring 9 just will be enclosed within the cylindrical of the clout release blank punch 2 on blank punch 2 so.Moved by hand clout enters stamping-out position next time.
