Description

The solid particle punch mould of band movable brake beads
Technical field
The utility model belongs to Stamping Die Technology, is specifically related to the solid particle punch mould with movable brake beads, mainly is at the alterable brake bead height, becomes the mould of punch shape.
Technical background
Present diel, 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 is difficult to solve.
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 the punch shape can't change in forming process, the problem of unbalance stress, a kind of mould that has the alterable brake bead height and become the solid particle amount is provided, thereby realize alterable brake bead resistance, become punch shape, stressed uniform problem, can prolong service life, the solution sealing problem of mould simultaneously.
The technical solution of the utility model is as follows: the solid particle punch mould of band movable brake beads comprises die, bead, blank holder, nitrogen cylinder, backing plate, die shoe, push rod; Blank holder is arranged on below the die, blank moulding in the die cavity of die; The nitrogen cylinder is installed on the die shoe, and its working end links to each other with blank holder; It is characterized in that: the briquetting lower end is installed on the die shoe, and the briquetting upper end is arranged in the hole of blank holder, and the briquetting upper end is corresponding with the die cavity of die, and blank holder moves up and down with respect to briquetting; On briquetting, be provided with solid particle; Between described briquetting, blank, the blank holder, form an enclosure space in forming process, described solid particle is full of enclosure space, and is corresponding with the die cavity of die as punch.
Be further characterized in that: be provided with at least one bead and backing plate, push rod is upwards passed by the die shoe bottom, and the push rod upper end contacts with backing plate; Blank holder is passed in described bead upper end, and the lower end is arranged on the backing plate, and push rod drives bead by backing plate and moves up and down.
Described bead is distributed on around the solid particle punch; The backing plate of bead lower end links into an integrated entity.
The topmost improvement of the utility model is with movable brake beads structure and a kind of novel die that is combined by solid particle shape-variable male die structure.
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.
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, safe and reliable, pollution-free in drawing process, and is very effective to improving the quality of products in the actual production.Simultaneously, the just solid particle of punch wearing and tearing in the use adds or the replacing solid particle in good time, in the corresponding service life that prolongs mould, has reduced production cost.
Description of drawings
Fig. 1 is the solid particle punch mould of the utility model band movable brake beads.
Among the figure: 1-die, 2-blank, 3-solid particle, 4-bead, 5-blank holder, 6-briquetting, 7-nitrogen cylinder, 8-backing plate, 9-die shoe, 10-push rod, 11-enclosure space
The specific embodiment
Referring to Fig. 1, be depicted as the solid particle punch mould of the utility model band movable brake beads, die 1, blank 2, solid particle 3, bead 4, blank holder 5, briquetting 6, nitrogen cylinder 7, backing plate 8, die shoe 9, push rod 10 etc.; Die 1 is installed on the inner slide and (does not illustrate among the figure), moulding in the die cavity of blank 2 in die 1; Blank holder 5 is arranged on below the die 1, and briquetting 6 is arranged in the hole of blank holder 5, and blank holder 5 moves up and down with respect to briquetting 6; Briquetting 6 lower ends are installed on the die shoe 9, and briquetting 6 upper ends are corresponding with the die cavity of die 1; Be provided with solid particle 3 in briquetting 6 upper ends.In forming process, briquetting 6 upper ends, blank 2, blank holder 5 form an enclosure space 11, and solid particle 3 is filled in the enclosure space 11, and solid particle 3 is as punch, and is corresponding with the die cavity of die 1.Before the matched moulds, on the upper surface of solid particle 3 briquetting 6 in the hole of blank holder 5.In drawing process, die 1 is descending, drives blank holder 5 and moves downward, solid particle 3 ejects in the hole of blank holder 5 with briquetting 6, is full of enclosure space 11, and solid particle 3 acts on the blank 2 as punch, forming process is finished in blank 2 moulding between die 1 and solid particle 3.Solid particle 3 of the present utility model 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 utility model and get final product.
In figure, the utility model mould also is provided with at least one independently bead 4, and blank holder 5 is passed in bead 4 upper ends, and the lower end is arranged on the backing plate 8, and push rod 10 upper surfaces contact with backing plate 8.Push rod 10 promotes backing plate 8 and moves up and down, and backing plate 8 promotes bead 4 and moves up and down synchronously, regulates the height (height that upwards passes from blank holder 5) that bead 4 exposes blank holder 5.Nitrogen cylinder 7 is arranged on the die shoe 9, and the working end of nitrogen cylinder 7 (cylinder axle head) withstands on the lower surface of blank holder 5, and cylinder 7 protrudes upward jack-up, provides blank holder 5 needed pressure-plate-forces; Cylinder 7 is two, and left-right symmetry distributes.Push rod 10 is connected with the air cushion of lathe, utilizes lathe air cushion self function, the size of the active force that adjusting push rod 10 is provided, thus the resistance of bead is changed along with the variation of punching stroke.Bead 4 among the figure is distributed on around solid particle 3 punch, and the resistance that uniform bead 4 is produced equates; The backing plate 8 of bead 4 lower ends is linked into an integrated entity, guarantee that uniform bead 4 moves up and down synchronously, it highly keeps identical, strengthens its running stability.
