Description
Technical field
The invention belongs to Stamping Die Technology, be specifically related to the mould with movable drawing rib and solid body particle medium radial thrust, mainly is at the alterable brake bead height, and the mould of radial thrust is provided simultaneously.
Technical background
Common shaping dies does not have radial thrust, is shaped to drive plate by punch, finishes to the die pulling.The cupping tool of band hydraulic radial, radial thrust are realized that by fluid pressure sealing problem is difficult to solve; Simultaneously, the cupping tool structure that has hydraulic means is complicated, and cost is higher.
Present diel, the convex tendon of bead are fixed on holding pad or the die usually, and the bead resistance is changeless in whole draw forming process.But along with punching stroke, requiring the bead resistance is the draw forming that changes for needs, and this fixed form just can't realize.Simultaneously, this bead is fixed on the mode on holding pad or the die, also is not easy to repair a die, sometimes may cause and scrap holding pad or die because bead can't repair, this has just increased repairing a die the time of mould, reduces the service life of mould, thereby increases production cost.Being called " a kind of mould with alterable brake bead resistance ", application number as the applicant in the name of on April 13rd, 2009 application is 200910103593.3 the disclosed mould structure of patent of invention, be provided with independently bead and bead backing plate, described bead passes from die, and the lower end is by end in contact on bead backing plate and the push rod.The present invention separates bead from die or holding pad, push rod promotes the motion of bead backing plate, and its resistance can change along with the variation of punching stroke, thereby but make bead height free adjustment by air cushion by the push rod free adjustment.
Summary of the invention
The present invention is directed to existing mold and can't change the insoluble problem of cupping tool sealing problem that alterable brake bead resistance and common shaping dies do not have radial thrust and band hydraulic radial, a kind of mould that has the alterable brake bead height and become the solid particle amount is provided, thereby realizes alterable brake bead resistance, provide radial thrust.Solve sealing problem.
Technical scheme of the present invention is as follows: the mould of band movable drawing rib and solid body particle medium radial thrust comprises patrix, punch, bead, holding pad, backing plate, die shoe, push rod.Patrix is installed on the inner slide, and punch is installed on the die shoe, compresses the nitrogen cylinder and is installed on the die shoe, and holding pad is withstood in the working end that compresses the nitrogen cylinder; It is characterized in that: liftout nitrogen cylinder is installed on die shoe, and the working end of liftout nitrogen cylinder penetrates holding pad, contacts with top board in being arranged on holding pad, withstands the lower surface of top board; Sealing plate is installed on the holding pad, sealing plate) in forming process, form an enclosure space with patrix, holding pad, top board and blank, solid particle is arranged in the enclosure space.
Further feature is: be provided with at least one bead and backing plate, holding pad is passed in described bead upper end, and the lower end is by end in contact on backing plate and the push rod.
Described bead is distributed on around the punch; The backing plate of bead lower end links into an integrated entity.
Described enclosure space is distributed in the holding pad.
The topmost improvement of the present invention is a kind of novel die that movable brake beads structure and the structure that is increased radial thrust by solid particle medium are combined
The present invention is big to the adjusting quantitative change of bead resistance, and convenient, and actual production is very effective to improving the quality of products.Simultaneously, this mold repair is convenient, can reduce mould and repair a die the time, prolongs the service life of mould, reduces production costs.
This mould structure is simple, and radial thrust is delivered on the plate by solid particle medium by liftout nitrogen cylinder, realizes reliable, pollution-free.This mould structure also can be realized binder by compressing the nitrogen cylinder, realizes radial thrust by the lathe air cushion.Compare with common shaping dies, it is easier to be shaped, and effect is very remarkable.
Description of drawings
Fig. 1 has the shaping dies of movable brake beads and radial thrust for the present invention.
Among the figure: the 1-patrix, the 2-punch, the 3-bead, 4-holding pad, 5-compress the nitrogen cylinder, 6-backing plate, 7-die shoe, 8-push rod, 9-sealing plate, 10-solid particle, 11-top board, 12-liftout nitrogen cylinder, 13-enclosure space.
The specific embodiment
Referring to Fig. 1, be depicted as the shaping dies that the present invention has movable brake beads and radial thrust, comprise patrix 1, punch 2, bead 3, holding pad 4 compresses nitrogen cylinder 5, backing plate 6, die shoe 7, push rod 8, sealing plate 9, solid particle 10, top board 11 and liftout nitrogen cylinder 12; Patrix 1 is installed on the inner slide and (does not illustrate among the figure), and patrix 1 is die normally; Punch 2 is installed on the die shoe 7, as counterdie punch normally.Compress nitrogen cylinder 5 and liftout nitrogen cylinder 12 also is installed on the die shoe 7, the working end that compresses nitrogen cylinder 5 contacts with the lower surface of holding pad 4, withstands the lower surface of holding pad 4; Compressing nitrogen cylinder 5 provides holding pad 4 needed pressure-plate-forces.Holding pad 4 is passed in the working end of liftout nitrogen cylinder 12, contacts with the lower surface of top board 11 in being arranged on holding pad 4 counterbores, withstands the lower surface of top board 11, promotes top board 11 upper and lower motions during 12 work of nitrogen cylinder.
Sealing plate 9 is installed on the holding pad 4, sealing plate 9 can form an enclosure space 13 with patrix 1, holding pad 4, top board 11 and blank in forming process, solid particle 10 is arranged in the enclosure space 13 (should be in the counterbore of holding pad 4 during moulding, when liftout nitrogen cylinder 12 raises, ejected by top board 11), thereby prevent that solid particle 10 from splashing away, can provide a thrust radially simultaneously, blank is subjected to the radial thrust of solid particle 10 in forming process; Among the figure on holding pad 4 formed enclosure space 13 be distributed in the holding pad 4, the radial thrust that solid particle 10 produced is equated.Under liftout nitrogen cylinder 12 effect, the solid particles 10 that top board 11 promotes in the enclosure spaces 13 move up and down synchronously, regulate what (solid particles 10 that flow out in the holding pad 4 what) that solid particle 10 flows out holding pads 4.Liftout nitrogen cylinder 12 is fixed on the die shoe 7, guarantees that the solid particle 10 in the uniform enclosure space moves up and down synchronously, guarantee that the quantity of the solid particle 10 of outflow holding pad 4 equates, strengthen its running stability; The assurance radial thrust equates.Solid particle 10 of the present invention is selected steel ball, steel ball or other metals or the plastic grain of suitable dimension for use, has suitable strength and stiffness, can satisfy needs of the present invention and get final product.
In figure, this mould also is provided with at least one independently bead 3, and holding pad 4 is passed in bead 3 upper ends, and the lower end contacts with push rod 8 upper surfaces by backing plate 6.Push rod 8 promotes backing plate 6 and moves up and down, and backing plate 6 promotes bead 3 and moves up and down synchronously, regulates the height (height that upwards passes from holding pad 4) that bead 3 exposes holding pad 4.Compress upwards jack-up of nitrogen cylinder 5, provide holding pad 4 needed pressure-plate-forces.Push rod 8 is connected with air cushion, utilizes lathe self function, the size of the active force that adjusting push rod 8 is provided, thus the resistance of bead is changed along with the variation of punching stroke.Bead 3 among the figure is distributed on around the punch 2, and the resistance that uniform bead 3 is produced equates; The backing plate 6 of bead 3 lower ends is linked into an integrated entity, guarantee that uniform bead 3 moves up and down synchronously, it highly keeps identical, strengthens its running stability.
