In the technology, the solid particles are applied in the thinned deep-drawing die and used for applying positive pressure; and compared with the common thinned deep-drawing die, the thinned deep-drawing die with positive pressure can effectively improving the deformation degree of products. Compared with the liquid medium, the solid particles media are utilized to apply pressure, the forming is easy to realize without special equipment, and the solid particles do not leak or pollute the environment, therefore, safe and reliable production can be realized.
Description
Technical field
The utility model belongs to the cupping tool technology, is specifically related to be with positive pressure ironing mould, utilizes solid particle medium to apply positive pressure, improves the product deformation extent.
Technical background
Common shaping dies, only by the drawing pressure of punch, being shaped drives plate by punch, finishes to the die pulling.The mould of band hydraulic medium assist formation, the fluid sealing problem is difficult to solve; Simultaneously, the cupping tool structure that has hydraulic means is complicated, and cost is higher.
Common die is shaped, by the drawing pressure of punch blank is drawn in die and realize ironing, drawing pressure is bigger in the forming process, be prone to drawing crack, the product damage, and wearing and tearing appear in mould easily, reduce the service life of mould, hydraulic pressure can't solve as the cupping tool sealing problem of medium, has potential safety hazard, and easily pollutes working environment.
Summary of the invention
The utility model is the bad and insoluble problem of hydro-drawing mould sealing problem at the existing mold forming quality, and band positive pressure ironing mould and method are provided, thereby improves product shaping quality, solution sealing problem.
The technical solution of the utility model is as follows: band positive pressure ironing mould, comprise upper bolster and die shoe, and it is characterized in that: die is arranged on the upper bolster by backing plate, and location-plate is arranged on below the die, is equipped with briquetting below the location-plate; Correspondence is provided with porosely on briquetting, location-plate, die and backing plate, and vertically the punch that is provided with passes the hole on briquetting, location-plate, the die, and the punch lower end is arranged on the die shoe; The working end of some push rods is passed die shoe and is contacted with briquetting;
Between the outside and briquetting of punch, be movably set with top board, top board and punch and briquetting are slidingly matched; The nitrogen cylinder is installed on the die shoe, and its cylinder axis contacts with the lower surface of top board;
Top board is provided with solid particle; Matched moulds also carries out drawing and forming when operation, between die, location-plate, briquetting, top board, punch and blank, forms an enclosure space, and solid particle is filled in the enclosure space;
Gap between punch and the die is less than the thickness of blank.
Further feature is: the nitrogen cylinder is distributed on around the punch.
The topmost improvement of the utility model is that solid particle medium is applied in the ironing mould, slab edge is applied a kind of novel die of positive pressure.Positive pressure passes to slab edge by nitrogen cylinder or air-cushion eject-rod by solid particle medium.
This mould structure is simple, and this mould structure utilizes solid particle medium to exert pressure, and compares with common ironing mould, can effectively improve the product deformation extent.Compare with liquid medium, be shaped and very easily realize, do not need special installation, and solid particle can not leak, free from environmental pollution, can realize safe and reliable production.
Description of drawings
Fig. 1 is the utility model band positive pressure ironing mould;
Fig. 2 is that the utility model mould is in the initialization structure graph.
Among the figure: 1-upper bolster, 2-backing plate, 3-die, 4-location-plate, 5-solid particle, 6-top board, 7-briquetting, 8-nitrogen cylinder, 9-push rod, 10-die shoe, 11-punch, 14-enclosure space, 15-blank.
The specific embodiment
Referring to Fig. 1, be depicted as the utility model band positive pressure ironing mould, comprise punch 11, die 3, push rod 9, nitrogen cylinder 8, briquetting 7, top board 6, solid particle 5, location-plate 4, backing plate 2, die shoe 10, upper bolster 1 etc.; Die 3 setting is installed on the upper bolster 1, is installed in below the upper bolster 1 by backing plate 2 shown in the figure, and upper bolster 1 can drive die 3(and comprise die 3 backing plates 2 under external force) down motion; Location-plate 4 is arranged on below the die 3, is equipped with briquetting 7 below the location-plate 4; Correspondence is provided with porosely on briquetting 7, location-plate 4, die 3 and backing plate 2, and vertically the punch 11 that is provided with passes the hole of briquetting 7, location-plate 4, die 3, and the lower end is arranged on the die shoe 10.The working end of some push rods 9 is passed die shoe 10 and is contacted with briquetting 7, the support force of matched moulds being provided for briquetting 7, or the jack-up briquetting 7 that makes progress.Between the outside and briquetting 7 of punch 11, be movably set with top board 6, top board 6 specifically is arranged in the hole of briquetting 7, is slidingly matched with punch 11 and briquetting 7; Nitrogen cylinder 8 is installed on the die shoe 10, and the lower surface of the top board 6 in its cylinder axis (working end) and the briquetting 7 contact, in upwards elongation or when shortening downwards, drive top board 6 moves up and down of cylinder axis.Top board 6 is provided with solid particle 5.Matched moulds also carries out drawing and forming when operation, between die 3, location-plate 4, briquetting 7, top board 6, punch 11 and blank 15, form an enclosure space 14, solid particle 5 is filled in the enclosure space 14, under the effect of nitrogen cylinder 8, solid particle 5 acts on the outer face of blank 15.Solid particle 5 is positioned at radial-sealing space 12 all the time, does not leak; Enclosure space 12 is by air cushion and nitrogen cylinder synergy control size.
In the drawing and forming process, die 3 moves downward, and punch 11 keeps motionless substantially or moves upward, the blank 15 that is placed on the punch 11 is drawn in the hole of die 3 gradually, because the thickness of blank 15 is bigger, gap between punch 11 and the die 3 is less than the thickness of blank 15, thereby can carry out ironing; Enclosure space 14 also diminishes when die 3 moves downward, and solid particle 5 end face to blank 15 under the effect of nitrogen cylinder 8 has an auxiliary thrust so that better be shaped.In the time of pull and stretch, blank 13 outer rims are subjected to the positive pressure from solid particle 5.This positive pressure is provided by nitrogen cylinder or air cushion.
Simultaneously, can regulate the size of initial solid particle 5 places in enclosure space 14 by the position that push rod 9 is regulated briquetting 7, in forming process, regulate the size of its thrust,, improve the deformation extent of product so that better control forming process with nitrogen cylinder 8.Nitrogen cylinder 8 is distributed on around the punch 11.
Patrix of the present utility model is made up of upper bolster 1, backing plate 2, die 3, location-plate 4, and counterdie of the present utility model is by solid particle 5, top board 6,, briquetting 7, nitrogen cylinder 8, push rod 9 and die shoe 10 are formed, and punch 11 is positioned at the cavity in the middle of the upper die and lower die.
Solid particle 5 of the present utility model mainly adopts steel ball, steel ball, Metal Ball or the suitable particle of other performances, satisfies the needs of moulding extruding.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
