Description
Technical field
The present invention relates to diel, specifically refer to a kind of diel, belong to the Stamping Die Technology field with movable brake beads.
Background technology
Diel mainly is made up of cope match-plate pattern, backing plate, punch, blank holder, die and die shoe, and punch is installed on the cope match-plate pattern through backing plate, and blank holder is installed on the backing plate through eccentric swage and is positioned at around the punch.Die is corresponding with punch and be installed on the die shoe.
Different modeling during formed product, diverse location place section differs greatly after the formed product that has, thereby has different influxs, and is treated as not, can cause the product after the moulding wrinkling to occur when influx difference is excessive.In order to eliminate this phenomenon, need on mould, bead be set the relevant position, regulate flowing of material artificially through bead, different section influx difference is diminished and avoid wrinkling.Present diel, bead are fixed on blank holder and the die usually, and the resistance of bead all is changeless in the whole process of drawing.But, need the resistance of bead to change along with the variation of punching stroke for a lot of situation.But existing bead fixedly installs pattern because resistance is unalterable, therefore can't satisfy this requirement.Simultaneously, this bead that is fixedly installed on blank holder and the die is not easy to during die trial revise, and increases to repair a die and the die trial time, reduces die life, thereby increases die cost.
Summary of the invention
To having the above-mentioned deficiency that diel can't change the bead resistance now, the purpose of this invention is to provide a kind of diel, thereby realize that the bead resistance is variable with movable brake beads.
Technical scheme of the present invention is achieved in that a kind of diel with movable brake beads; Comprise cope match-plate pattern, backing plate, punch, blank holder, die, bead and die shoe; Bead is arranged on the die; Be provided with the wedge drive block at the cope match-plate pattern lower surface, wedge drive block lower end has the driving inclined-plane; Guide rail is installed on die shoe, and on guide rail, being provided with the receive wedge drive block promotion corresponding with wedge drive block driving inclined-plane can be along the wedge Slave Block of guide rail slip; On the wedge Slave Block, be provided with tooth bar, the engagement of tooth bar and a travelling gear is installed in the rotating shaft of this travelling gear and is provided with cam simultaneously; The following end in contact of said cam and bead, the bead upper end passes from the die upper surface.
Further, said wedge drive block lower end is fixed with the wedge slide block, and said driving inclined-plane is located on the wedge slide block.
Said bead is four that are positioned at around the punch; Corresponding wedge drive block is four and is located on four angles of cope match-plate pattern lower surface; Each piece wedge drive block corresponding one group of guide rail, wedge Slave Block, tooth bar, travelling gear and cam, around this structure can make the resistance of bead equate with steadily.
The present invention is in whole draw forming process, and the bead height changes and changes along with punching stroke, has realized the automatic flexible to the bead height, thereby reaches the purpose of the bead resistance of adjusting needs.Because bead height and resistance are convenient to control, and be easy to adjust, very effective in the actual production to improving the stamping products quality, can control metal forming flexibly, the partial plastic forming rate can improve more than 30%.
Simultaneously, this diel is simple in structure, and maintenance, easy accessibility reduce die trial and repair a die the time greatly, prolongation die life, reduces cost.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is described further.
Referring to Fig. 1; On scheming, can find out; The present invention has the diel of movable brake beads, and is the same with prior art, and this diel mainly comprises cope match-plate pattern 1, backing plate 2, punch 3, blank holder 4, die 5, bead 6 and die shoe 10; Punch 3 is installed on the cope match-plate pattern 1 through backing plate 2, and blank holder 4 is installed on the backing plate 2 through eccentric swage 12 and is positioned at around the punch 3.Die 5 and punch 3 are corresponding and be installed on the die shoe 10.Between cope match-plate pattern 1 and die shoe 10, be provided with guide pillar 7 and guide pin bushing 9, so that punching stroke is led.
Though bead 6 of the present invention also independently is arranged on the die 5, do not fixedly install, but in punching stroke changes relatively die move up and down, thereby adjusting bead resistance.Its concrete implementation is: be provided with wedge drive block 11 at cope match-plate pattern 1 lower surface, wedge drive block 11 lower ends have the driving inclined-plane; Guide rail 18 is installed on die shoe 10, and on guide rail 18, being provided with the receive wedge drive block promotion corresponding with wedge drive block driving inclined-plane can be along the horizontal wedge Slave Block 17 that slides of guide rail; On wedge Slave Block 17, be provided with tooth bar 15, tooth bar 15 and a travelling gear 14 engagement are installed in the rotating shaft of this travelling gear and are provided with cam 8 simultaneously; Said cam 8 and 6 times end in contact of bead, bead 6 upper ends pass from die 5 upper surfaces.
Said wedge drive block 11 lower ends are fixed with wedge slide block 16, and said driving inclined-plane is located on the wedge slide block 16.
Said bead is four that are positioned at around the punch; Corresponding wedge drive block is four and is located on four angles of cope match-plate pattern lower surface; Each piece wedge drive block corresponding one group of guide rail, wedge Slave Block, tooth bar, travelling gear and cam, around this structure can make the resistance of bead equate with steadily.
Operation principle of the present invention: during mould closes; Cope match-plate pattern 1 moves down with wedge drive block 11; The inclined-plane of wedge drive block 11 drives wedge Slave Block 17 and on guide rail 18, laterally slides, and the tooth bar 15 on the wedge Slave Block 17 is meshed with travelling gear 14, rotates so drive travelling gear 14; And then drive cam 8 rotates; Because contact with it on the cam 8 is dropped in the lower end of bead 6,, realize that thus the bead resistance changes along with the variation of punching stroke so cam 8 can realize that bead 6 exposes the height change of die and plate 13 contact portions when rotating.Two beads 6 are symmetricly set on the both sides of punch 3 about among Fig. 1.Reality can also be provided with same bead in the other both sides of punch when mould designs, the resistance of the bead around making equates that each piece bead has same control structure with steady.
The topmost improvement of the present invention is to separate bead from die or blank holder; Adjust the bead height with Wedge mechanism, pinion and rack and cam mechanism; Utilize Wedge mechanism as power resources; Rotate with driven gear tooth bar and cam, to realize the variation of movable brake beads height, the variation of bead height becomes along with punching stroke.
