Description
Technical field
The utility model relates to a kind of diel, relates in particular to a kind of side opening dual-direction ram mould.
Background technology
In punching production; Usually need punching on jatharapanvartanasana workpiece (like cylindrical member, box part, large-scale covering etc.) sidewall; Generally be to use the cantilevered perforating die, the die of existing cantilevered perforating die is horizontally disposed with, and need be placed in towards the workpiece of side opening on the die; Vertical punch moves downward under the drive of forcing press, accomplishes the moulding of side opening.Existing cantilevered perforating die has only a punch; A punching press can only be dashed a hole, if the jatharapanvartanasana workpiece need be on sidewall symmetry dash two holes, use existing cantilevered perforating die just to need earlier in hole of a side blow; Then with workpiece Rotate 180 degree again towards another hole; So very inconvenient, productivity ratio is low, and if the inaccurate precision that usually causes workpiece in location, rotation back low even scrap.
Summary of the invention
To the problem that above-mentioned prior art exists, the utility model provides a kind of side opening dual-direction ram mould, can one-shot forming workpiece sidewall on two holes of symmetry, do not need resetting, improved the precision of productivity ratio and product.
The technical scheme of the utility model is: a kind of side opening dual-direction ram mould; Comprise upper bolster, die shoe, die shank, go up punch, guide pin bushing and guide pillar; Last punch is arranged at the upper bolster lower surface, is socketed with holding pad on the last punch, and holding pad is provided with the binder screw; Be socketed with rubber blanket on the binder screw, rubber blanket adopts polyurethane rubber to process; Position corresponding with last punch on the die shoe is provided with lower punch; Be provided with movable matrix between last punch and the lower punch; Movable matrix is movably connected on the die shoe top, and the position corresponding with upper and lower punch, the upper and lower surface of movable matrix has the die hole, and die is provided with reinforcing sleeve in the hole.
As preferably; Last punch is fixedly connected on the upper bolster lower surface through last punch retainer; The position that the upper bolster lower surface is corresponding with last punch is provided with upper padding plate, and lower punch is fixedly connected on the die shoe top through the lower punch fixed head, is provided with lower bolster between lower punch and the die shoe.
As preferably; Be vertically installed with little guide pillar on the die shoe; Movable matrix is socketed on the little guide pillar through little guide pin bushing, and movable matrix is vertical with little guide pillar and can slide up and down along little guide pillar, and the two sections sidewall surfaces that little guide pillar and movable matrix are corresponding is respectively arranged with upper limit position block and lower position block.
The beneficial effect of the utility model is: last punch of the utility model and lower punch position are corresponding; During punching press workpiece is enclosed within on the movable matrix, in punching stroke, last punch and lower punch can be accomplished the moulding in two holes of workpiece sidewall symmetry simultaneously; Need not be with the workpiece resetting; Practice thrift operation, boost productivity, and improved the precision of product.Upper limit position block and lower position block can guarantee the positional precision of movable matrix, avoid movable matrix under the effect of last punch and lower punch, to depart from its operating position.Reinforcing sleeve in the die hole can increase the intensity of movable matrix, increases the service life of movable matrix, and the upper padding plate of upper bolster lower surface can slow down goes up the impact of punch to upper bolster, prolongs the service life of upper bolster.The rubber blanket of socket has further increased pressure-plate-force on the binder screw, prevents that surface of the work is wrinkling, the polyurethane rubber good springiness, and intensity is high, and the gentle write-downs of wearability pinking is good, long service life.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
A kind of embodiment as the utility model; As shown in Figure 1; A kind of side opening dual-direction ram mould comprises upper bolster 1, die shoe 2, die shank 3, goes up punch 4, guide pin bushing 17 and guide pillar 18, and last punch 4 is arranged at upper bolster 1 lower surface; Be socketed with holding pad 7 on the last punch 4, the lower surface of holding pad 7 flushes with the lower surface of last punch 4.Holding pad 7 is provided with the binder screw, is socketed with rubber blanket 8 on the binder screw, and rubber blanket 8 adopts polyurethane rubber to process; The polyurethane rubber good springiness, intensity is high, and the gentle write-downs of wearability pinking is good, long service life.Rubber blanket 8 can increase the pressure of 7 pairs of workpiece of holding pad.
Be provided with lower punch 10 with last punch 4 corresponding positions on the die shoe 2; Be provided with movable matrix 9 between last punch 4 and the lower punch 10; Movable matrix 9 is movably connected on die shoe 2 tops, in the present embodiment, and as preferably; Be vertically installed with little guide pillar 13 on the die shoe 2; Movable matrix 9 is socketed on the little guide pillar 13 through little guide pin bushing 14, and movable matrix 9 and little guide pillar 13 are vertical and can slide up and down along little guide pillar 13, and little guide pillar 13 is respectively arranged with upper limit position block 15 and lower position block 16 with movable matrix 9 corresponding two sections sidewall surfaces.Movable matrix 9 upper and lower surfaces have the die hole with upper and lower punch 4,10 corresponding positions, are provided with reinforcing sleeve 19 in the die hole.Reinforcing sleeve 19 can increase the intensity of movable matrix 9, prolongs the service life of movable matrix 9.
Last punch 4 is fixedly connected on upper bolster 1 lower surface through last punch retainer 5; Upper bolster 1 lower surface is provided with upper padding plate 6 with last punch 4 corresponding positions; In the present embodiment; Upper bolster 1 lower surface has circular trough with last punch 4 corresponding positions, and upper padding plate 6 is arranged in the circular trough, and the lower surface of upper padding plate 6 flushes with the lower surface of upper bolster 1.Lower punch 10 is fixedly connected on die shoe 2 tops through lower punch fixed head 11, is provided with lower bolster 12 between lower punch 10 and the die shoe 2.
The course of work of the utility model is following: when stamping-out; The starting pressure machine; Upper bolster 1 is descending under the drive of forcing press through die shank 3, and it is descending with after lower punch 10 contacts that last punch 4 drives movable matrix 9, accomplishes the moulding in two symmetrical holes of workpiece 20 sidewalls simultaneously.Forcing press arrival after bottom dead center begins up, and upper bolster 1 is got back to initial position, waits for stamping-out next time.
