Abstract

The utility model discloses a stretching mould, which comprises an upper mould part and a lower mould part, wherein the upper mould part comprises an upper mould holder, an upper base plate, an upperplywood, a pressure plate and an ejector rod; and the lower mould part comprises a lower mould holder, a lower base plate, a lower mould plate, a blanking die and an ejector rod. The stretching mouldhas relatively simple structure and reasonable design; with the adoption of the unique design, the stretching mould has good self-lubricating property, high rigidity and small friction coefficient; meanwhile, the material flowability is good, and no scratch is caused on the product; in addition, the service life of the mould is improved, and the mould is not easy to be deformed.

Description

A kind of drawing die
Technical field
The utility model relates to Tool and Die Technology, especially relates to the drawing die that is applied to the product drawing and forming.
Background technology
Drawing die is that modern product is made a kind of mould that widely use in the field, is made of the concavo-convex die combination that cooperates up and down usually, and each concavo-convex mould all has a die holder separately, and die holder is provided with the template of moulding.Generally, if when the outer shape of raw product is relatively slick and sly, template surface also is slick and sly, and at this moment, can there be the cutting edge part in die surface, mould life-span generally also can be long.But during reality is used; the outer shape of most of products is not very slick and sly; therefore; for its template surface that designs can be very not slick and sly yet; often have the cutting edge part, these cutting edge parts can cause damage to mould usually, shorten the life-span of mould; also can influence simultaneously the flowability of material, make product produce scratch.
The utility model content
The technical problems to be solved in the utility model provide a kind of rational in infrastructure, the life-span long, indeformable, drawing die that self-lubricity is good.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of drawing die, comprise part of the upper die and part of the lower die, the part of the upper die comprises upper bolster, upper padding plate, train wheel bridge, holding pad, knock-pin etc., the part of the lower die comprises die shoe, lower bolster, lower bolster, blanking die, push rod etc., it is characterized in that: knock-pin is fixed on the upper bolster, upper bolster passes upper padding plate by screw and is fixed to train wheel bridge, the stretching die passes train wheel bridge and is fixed on the upper padding plate, straight rod type punch and knock-pin are fixed, the straight rod type punch is located in the stretching die, and the straight rod type punch can move up and down in stretching die inside, and holding pad is connected to train wheel bridge; Die shoe and lower bolster are fixed together, stretching convex die is fixed on the die shoe, lower bolster is fixed on the die shoe by screw, and lower bolster is provided with the hole, and blanking die is located in the counterdie plate hole, lower bolster is provided with the free gap, die opening state, blanking die flushes with lower bolster, and push rod withstands the blanking die bottom, when work, push rod is used for the jack-up blanking die; Upper bolster is connected the location with die shoe by guide pillar.
The utility model structure is simple relatively, reasonable in design, adopt unique design, make that the utility model self-lubricity is good, hardness is high, coefficient of friction is little, simultaneously good, the product of material flowability can not produce scratch, and improved mould life-span, make it not yielding.
Description of drawings
Fig. 1 is the positive cross-sectional schematic of the utility model.
Among the figure, 1 is upper bolster, and 2 is die shoe, and 3 is upper padding plate, and 4 is lower bolster, and 5 is train wheel bridge, and 6 is stretching convex die, and 7 are the stretching die, and 8 is the straight rod type punch, and 9 is holding pad, and 10 is lower bolster, and 11 is blanking die, and 12 is knock-pin, and 13 is guide pillar, and 14 is push rod.
The specific embodiment
In the present embodiment, with reference to Fig. 1, described drawing die comprises part of the upper die and part of the lower die, the part of the upper die comprises upper bolster 1, upper padding plate 3, train wheel bridge 5, holding pad 9, knock-pin 12 etc., and the part of the lower die comprises die shoe 2, lower bolster 4, lower bolster 10, blanking die 11, push rod 14 etc.Knock-pin 12 is fixed on the upper bolster 1, upper bolster 1 passes upper padding plate 3 by screw and is fixed to train wheel bridge 5, stretching die 7 passes train wheel bridge 5 and is fixed on the upper padding plate 3, straight rod type punch 8 and knock-pin 12 are fixing, straight rod type punch 8 is located in the stretching die 7, straight rod type punch 8 can move up and down in stretching die 7 inside, and holding pad 9 is connected to train wheel bridge 3; Die shoe 2 is fixed together with lower bolster 4, stretching convex die 6 is fixed on the die shoe 2, lower bolster 10 is fixed on the die shoe 2 by screw, and lower bolster 10 is provided with the hole, and blanking die 11 is located in lower bolster 10 holes, lower bolster 10 is provided with the free gap, die opening state, blanking die 11 flushes with lower bolster 10, and push rod 14 withstands blanking die 11 bottoms, when work, push rod 14 is used for jack-up blanking die 11; Upper bolster 1 is connected the location with die shoe 2 by guide pillar 13.
