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.
Common die is made by punching block, and punch shape in drawing process is constant.This mould is easy unbalance stress in drawing process, occurs the drawing crack phenomenon easily, and the service life of reduction mould, thereby increase production cost wearing and tearing appear, in mould easily.Hydro-drawing mould sealing problem can't solve, and has potential safety hazard, and easily pollutes working environment.
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 utility model is separated 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 utility model can't change alterable brake bead resistance at existing mold and common shaping dies does not have radial thrust, the punch shape is immutable and the insoluble problem of hydro-drawing mould sealing problem, 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, become the punch shape, radial thrust is provided, solves sealing problem.
The technical solution of the utility model is as follows: a kind of forming die with shape-variable male die with controlled brake beads and radial thrust comprises die, the shaping solid particle, bead, blank holder, clamping cylinder, backing plate, die shoe, push rod, briquetting, the liftout cylinder, top board, radial solid particle, sealing plate, blank etc.Die is installed on the inner slide, and briquetting is installed on the die shoe, and clamping cylinder is installed on the die shoe, and blank holder is withstood in the working end of clamping cylinder; It is characterized in that: the liftout cylinder is installed on die shoe, and the working end of liftout cylinder penetrates holding pad, contacts with top board in being arranged on blank holder, withstands the lower surface of top board; Sealing plate is installed on the blank holder, and sealing plate and die, blank holder, top board and blank form a radial-sealing space in forming process, and the radial solid particle is arranged in the radial-sealing space.
Another feature is: also be provided with by briquetting, blank, blank holder form a shaping enclosure space in forming process, and the shaping solid particle is arranged in the shaping enclosure space, as punch.
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 shaping solid particle punch; The backing plate of bead lower end links into an integrated entity.
Described radial-sealing space is distributed in the blank holder.
The topmost improvement of the utility model is that this patent is with movable brake beads, solid particle punch, radially increases a kind of novel die that thrust combines with solid particle medium.
The utility model 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 the liftout cylinder, realizes reliable, pollution-free.This mould structure also can be realized binder by clamping 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.
Punch of the present utility model is to be made of the solid particle that becomes second nature in the shaping enclosure space, and punch is shape variable, stressed even in drawing process, and is very practical.Safe and reliable and very effective in the actual production to improving the quality of products.Simultaneously, the just solid particle of punch wearing and tearing in the service life of prolongation mould, reduces production costs in the use.
