Description

The two-way blanking die of side opening

Technical field

The utility model relates to a kind of diel, relates in particular to the two-way blanking die of a kind of side opening.

Background technology

In punching production, usually need punching on jatharapanvartanasana workpiece (as 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, need be placed in towards the workpiece of side opening on the die, vertical punch moves downward under the drive of forcing press, finishes 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 rotation back location low even scrap.

Summary of the invention

At the problem that above-mentioned prior art exists, the utility model provides a kind of side opening two-way blanking die, 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 solution of the utility model is: the two-way blanking die of a kind of side opening, 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, be respectively arranged with the fiberglass anticorrosive coat on guide pin bushing and the guide pillar, be socketed with holding pad on the last punch, holding pad is provided with the binder screw, is socketed with rubber blanket on the binder screw, and rubber blanket adopts polyurethane rubber to make; 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 by 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 by 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 by 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 of little guide pillar and movable matrix correspondence is respectively arranged with upper limit position block and lower position block.

The beneficial effects of the utility model are: punch and the lower punch position correspondence of going up of the present utility model, during punching press workpiece is enclosed within on the movable matrix, in punching stroke, last punch and lower punch can be finished the moulding in two holes of workpiece sidewall symmetry simultaneously, need not be with the workpiece resetting, save 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 to depart from its operating position under the effect of last punch and lower punch.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 the intensity height, the gentle write-downs of wearability pinking is good, long service life.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

As a kind of embodiment of the present utility model, as shown in Figure 1, the two-way blanking die of a kind of side opening, comprise upper bolster 1, die shoe 2, die shank 3, go up punch 4, guide pin bushing 17 and guide pillar 18, last punch 4 is arranged at upper bolster 1 lower surface, be respectively arranged with the fiberglass anticorrosive coat on guide pin bushing 17 and the guide pillar 18, improved service life of the present utility model.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 make; The polyurethane rubber good springiness, the intensity height, 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.

Position corresponding with last punch 4 on the die shoe 2 is provided with lower punch 10, 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, 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 by little guide pin bushing 14, movable matrix 9 and little guide pillar 13 are vertical and can slide up and down along little guide pillar 13, and the two sections sidewall surfaces of little guide pillar 13 and movable matrix 9 correspondences is respectively arranged with upper limit position block 15 and lower position block 16.Movable matrix 9 upper and lower surfaces and upper and
