Abstract
A drawing die comprises an upper die part and a lower die part. An ejector rod is fixed on an upper die seat; the upper die seat is fixed on an upper splint by screw penetrating through an upper base plate. A drawing concave die penetrates through the upper splint and is fixed on the upper base plate 3. A straight rod type convex die is fixed together with the ejector rod and arranged in the drawing concave die. A pressing plate is connected to the upper splint, a lower die seat is fixed with a lower base plate, a drawing convex die is fixed on the lower die seat, a lower die plate is fixed on the lower die seat through a screw, the lower die plate is provided with a hole, a blanking punch is arranged in the hole of the lower die plate, and a mandril jacks the bottom of the blanking punch. The drawing die has the advantages of relatively simple structure, reasonable design, unique design, good self-lubricating property, high rigidity and small friction coefficient. Meanwhile, the flowability of the materials is good, the scratching of a product is avoided, the service life of the die is prolonged, and the die is not easily deformed.
Description
Technical field
The present invention relates to technical field of mold, relate in particular to a kind of drawing die.
Background technology
Drawing die is that widely use-kind of mould in the suitable field of modern product system, is usually constituted by the concave-convex mold that cooperates up and down, and each concave-convex mold 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 rounder and more smooth, template surface also is round and smooth, 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 products is not very round and smooth; therefore; for its template surface that designs can be very not round and smooth 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 affect simultaneously the flowability of material, make product produce scratch.
Summary of the invention
The defects that exists in order to overcome traditional drawing die, the invention provides a kind of provide a kind of rational in infrastructure, the life-span long, indeformable, drawing die that self-lubricity is good.
The technical scheme that the present invention adopts for achieving the above object is: 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., 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 with fixing on upper padding plate seven, straight rod type punch and knock-pin are fixed, the straight rod type punch is located in the stretching die, holding pad is connected to train wheel bridge, and die shoe and lower bolster are fixed together, and stretching convex die is fixed on the die shoe, lower bolster is fixed on the die shoe by screw, lower bolster is provided with the hole, and blanking die is located in the counterdie plate hole, and push rod withstands the blanking die bottom.
Described upper bolster is connected guide pillar and is connected the location with die shoe.
Drawing die of the present invention, the type structure is relatively simple, reasonable in design, adopts unique design, so that self-lubricity of the present invention 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 structural representation of drawing die of the present invention.
The specific embodiment
The structure of drawing die of the present invention as shown in Figure 1, comprise part of the upper die and part of the lower die, the part of the upper die comprises clay model seat 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 l, 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, holding pad 9 is connected to train wheel bridge 3, die shoe 2 fixes on lower bolster 4 states, 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 fence material drift 11 is established in sub-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 the jack-up blanking, and middle 11, upper bolster l is connected with die shoe by the property led 13 connection location.
