Abstract

The utility model discloses a cantilever type bidirectional punching die and relates to a stamping die. The punching die comprises an upper die holder, a lower die holder, a die handle, an upper male die, a guide sleeve and a guide column, wherein the upper male die is provided with a discharging plate; a discharging spring is arranged on the discharging plate; a lower male die is arranged on the lower die holder correspondingly to the upper male die; a movable female die is arranged between the upper male die and the lower male die; a small guide column is vertically arranged on the lower die holder; the movable female die is sleeved and connected on the small guide column by the small guide sleeve; the movable female die is vertical to the small guide column and can slide up and down along the small guide column; an upper limit block and a lower limit block are respectively arranged on the upper side wall surface and the lower side wall surfaces corresponding to the small guide column and the movable female die; female die holes are respectively arranged at the position corresponding to the upper male die on the upper surface of the movable female die and at the position corresponding to the lower male die on the lower surface of the movable female die; and the female die holes are internally provided with reinforced sleeves. In the utility model, two symmetric holes can be formed on the side wall of a workpiece in one step, and repeated positioning is not required, so that the production efficiency and the precision of the product are improved, and the practicability is good.

Description

A kind of cantilevered bidirectional punching mould

Technical field

The utility model relates to a kind of diel, relates in particular to a kind of cantilevered bidirectional punching mould.

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 cantilevered bidirectional punching mould, can one-shot forming workpiece sidewall on two holes of symmetry, do not need resetting, improved the precision of productivity ratio and product, very practical.

The technical solution of the utility model is: a kind of cantilevered bidirectional punching mould, comprise upper bolster, die shoe, die shank, go up punch, guide pin bushing and guide pillar, last punch is fixedly connected on the upper bolster lower surface by last punch retainer, last punch is provided with stripper, stripper is provided with the discharging spring, position corresponding with last punch on the die shoe is provided with lower punch, 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; Be provided with movable matrix between last punch and the lower punch, 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, 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 position that position that the movable matrix upper surface is corresponding with last punch and lower surface and lower punch are corresponding has the die hole, and die is provided with reinforcing sleeve in the hole.

As preferably, the position that the upper bolster lower surface is corresponding with last punch is provided with upper padding plate.

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, very practical.

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, a kind of cantilevered bidirectional punching mould, 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 fixedly connected on upper bolster 1 lower surface by last punch retainer 5, last punch 4 is provided with stripper 7, stripper 7 is provided with discharging spring 8, position corresponding with last punch 4 on the die shoe 2 is provided with lower punch 10, lower punch 10 is fixedly connected on die shoe 2 tops by lower punch fixed head 11, is provided with lower bolster 12 between lower punch 10 and the die shoe 2; Be provided with movable matrix 9 between last punch 4 and the lower punch 10, 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; Position that movable matrix 9 upper surfaces and last punch 4 are corresponding and lower surface and lower punch 10 corresponding positions have the die hole, are provided with reinforcing sleeve 19 in the die hole.

As preferably, upper bolster 1 lower surface and last punch 4 corresponding positions are provided with upper padding plate 6.In the present embodiment, upper bolster 1 lower surface and last punch 4 corresponding positions have rectangular channel, and upper padding plate 6 is arranged in the rectangular channel, and the lower surface of upper padding plate 6 flushes with the lower surface of upper bolster 1.

The course of work of the present utility model is as follows: when stamping-out, the starting pressure machine, upper bolster 1 is descending under the drive of forcing press by die shank 3, and last punch 4 drive movable matrixes 9 are descending with after lower punch 10 contacts, and finish the moulding in two holes of workpiece 20 sidewall symmetries 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.
