Abstract
The utility model relates to a press-through die, comprising a drawing cavity die, a drawing terrace die, a drawing ring, a pressing plate, a base, an ejector pin, a spring, an adjusting bolt, an adjusting plate, a bearing body and a drawing rib. The drawing terrace die is fixed on the base through the pressing plate, the pressing plate is fixed on the base through the bearing body, and the bearing body is provided with a connecting plate. The lower end of the drawing ring is provided with the ejector pin, the adjusting plate and the spring, and is fixed by the adjusting bolt. The drawing ring is arranged between the bearing body and the drawing terrace die, and the upper surface of the drawing ring is provided with the drawing rib or a drawing rib groove. The corresponding place on the lower surface of the drawing cavity die is provided with the drawing rib groove or the drawing rib. A drawing concave mould is above the drawing ring, and is fixedly connected with a press machine. The utility model has the advantages of simple structure, good drawing effect, low cost of manufacturing, improved material using ratio, etc, and in particular has notable effect of deep drawing and forming for the materials with poor drawing performance.
Description
Technical field
The utility model belongs to the deep-drawing pressure processing technology, particularly a kind of mould of pressure-pad-force when adopting bead control stock of square deep-drawing.
Background technology
Traditional cylindrical part deep-drawing technology is to adopt circular blank to carry out draw forming, and the circular slab material of band steel plate shearing the time, the metal material in its bight just becomes waste material, has reduced stock utilization like this, has therefore increased processing cost.If adopt stock of square deep-drawing shaping cylindrical part, make the amount of flow of the amount of flow of bight metal by the control pressure-pad-force, thereby the distortion of inhomogeneities when having realized the stock of square deep-drawing has improved stock utilization greater than straight flange district metal.At present, the method that adopts combination blank holder control pressure-pad-force is arranged also, but the drawing die complex structure, the die manufacturing cost height, processing technology is poor.For the relatively poor material of drawing property, also exist a lot of deficiencies.
The utility model content
The purpose of this utility model is the problem that exists at existing deep-drawing technology, provide a kind of simple in structure, easy to operate, draw forming is effective, a kind of deep-drawing mould of economical with materials, the mould of pressure-pad-force when promptly adopting bead control stock of square deep-drawing.
The utility model comprises and draws die, draw punch, blank holder, pressing plate, base, push rod, spring, regulate bolt, adjustable plate, supporting mass, bead, drawing punch is fixed on the base by pressing plate, pressing plate is fixed on the base by supporting mass, supporting mass is provided with connecting plate, the lower end of blank holder is provided with push rod, adjustable plate and spring, and by regulating bolting, blank holder is arranged on supporting mass and draws between the punch, upper surface at blank holder is provided with bead or bead groove, be provided with bead groove or bead at the correspondence position that draws the die lower surface, draw die above blank holder, and fixedly connected with forcing press.
Operation principle of the present utility model is: the straight flange district at stock of square is provided with bead, unit blank holder force at folding corner region is applied by spring, straight flange zone at stock of square adopts bead to increase unit blank holder force, make the unit blank holder force of bight unit blank holder force less than the straight flange district, therefore when draw forming, the metal flow momentum of folding corner region so just can make full use of the metal in bight greater than the amount of flow of straight flange district metal, improve the utilization rate of material, and guaranteed to draw effect.
The utlity model has simple in structure, draw advantages such as effective, low cost of manufacture and raising stock utilization, especially remarkable to the relatively poor material deep-drawing of drawing property forming effect.
Description of drawings
Fig. 1 is a mould structure schematic diagram of the present utility model;
Fig. 2 is the utility model bead groove structural representation;
Fig. 3 is that the utility model bead is the split structural representation;
Fig. 4 is the utility model bead and the blank holder schematic diagram that is structure as a whole;
Among Fig. 1: 1 draws die, 2 drawn components, 3 draws punch, 4 blank holders, 5 pressing plates, 6 bases, 7 push rods, 8 springs, 9 and regulates bolts, 10 adjustable plates, 11 supporting masses, 12 beads.
The specific embodiment
As shown in the figure, in conjunction with the embodiments the technical solution of the utility model is described further.
As shown in Figure 1, a kind of deep-drawing mould, it comprises draws die 1, draws punch 3, blank holder 4, pressing plate 5, base 6, push rod 7, spring 8, regulates bolt 9, supporting mass 11, adjustable plate 10, bead 12.Drawing punch 3 is fixed on the base 6 by pressing plate 5, pressing plate 5 is fixed on the base 6 by supporting mass 11, be fixed with connecting plate by screw on the supporting mass 11, blank holder 4 is arranged on supporting mass 11 and draws between the punch 3, the lower end of blank holder 4 is provided with push rod 7, adjustable plate 10 and spring 8, and by the size of regulating the fixing and regulating spring power of bolt 9, drawing die 1 is arranged on the top of drawing punch 3 and fixedlys connected with forcing press, the upper surface of blank holder 4 is provided with bead 12, simultaneously be provided with the bead groove in the relevant position of drawing die 1 lower surface, perhaps be provided with bead 12 at the lower surface that draws die 1, simultaneously be provided with the bead groove in the relevant position of blank holder 4 upper surfaces, the structure of bead groove as shown in Figure 2.Bead 12 is with blank holder 4 or draw die 1 and be made of one structure, perhaps for dividing body structure, bead and blank holder for the branch body structure as shown in Figure 3, bead and blank holder are structure as a whole as shown in Figure 4.Owing to adopt technique scheme, so effective through the drawn component 2 of deep-drawing shaping, it is wrinkle resistant not break.Operation principle of the present utility model is: the straight flange district at stock of square is provided with bead, do not design bead at folding corner region, the pressure-pad-force of comer area is applied by spring, straight flange zone at stock of square adopts bead to increase pressure-pad-force, make the unit blank holder force of bight unit blank holder force less than the straight flange district, therefore when draw forming, the amount of flow of bight metal is greater than the amount of flow of straight flange district metal, so just can make full use of the metal in bight, thereby improve stock utilization.
