Description

Wedge type is towards the side opening mould
Technical field
The utility model relates to a kind of diel, relates in particular to a kind of Wedge type towards the side opening mould.
Background technology
In punching production, usually need be at the jatharapanvartanasana workpiece (as cylindrical member, box part, large-scale covering etc.) punching on the sidewall, generally be to use the cantilevered perforating die, the die of this mould 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, finish the moulding of side opening, 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, need resetting like this, very inconvenient, productivity ratio is low, and if the inaccurate precision that usually causes workpiece in rotation back location low even scrap.
The utility model content
At the problem that above-mentioned prior art exists, the utility model provides a kind of Wedge type towards the side opening 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 Wedge type comprises upper bolster, die shoe, die shank, punch and die towards the side opening mould, and die is fixed on the die shoe by die block; The relative bilateral symmetry of die sidewall has the die hole, the both sides that the die block upper surface is corresponding with the die hole have chute and are respectively arranged with angled-lift splits and block, angled-lift splits can slide along chute, block is arranged at the side of angled-lift splits away from die, punch is fixed in angled-lift splits near the position corresponding with the die hole on the side of die by punch retainer, and the punch sidewall surfaces is coated with rubber press; The bottom surface of angled-lift splits has half groove, the opening of half groove is positioned at the side of angled-lift splits near die, along continuous straight runs is provided with the screw that resets in half groove, the screw that resets is provided with back-moving spring, be provided with postive stop baffle near the opening of half groove and the position corresponding with the screw that resets on the die block, the end face of postive stop baffle is lower than the bottom surface of half groove; Angled-lift splits is provided with the inclined-plane away from an end of die, and the position corresponding with angled-lift splits, upper bolster two ends is respectively arranged with the wedge with the angled-lift splits coupling, and wedge is fixed on the upper bolster by upper mounted plate, and the inclined working of wedge is provided with the abrasionproof cushion block.
As preferably, also comprise the pressing plate that the position is corresponding with die, pressing plate is connected in the die shank by push rod, and push rod can slide in die shank, and pressing plate is provided with holddown spring.
As preferably, die block is provided with guide plate.
The beneficial effects of the utility model are: after adopting said structure, when stamping-out, upper bolster is descending under the drive of forcing press by die shank, the wedge of both sides contacts with the angled-lift splits of both sides, and angled-lift splits is moved horizontally simultaneously, finishes the punching of both sides simultaneously, like this need not be with the workpiece resetting, save operation, boost productivity, and improved the precision of product.The abrasionproof cushion block can prevent the wedge wearing and tearing, prolongs the service life of wedge.Rubber press on the punch can be when punching the workpiece pressing sidewall, avoid wrinkling, improve the product precision.When forcing press was descending, pressing plate with Work-sheet pressing, guaranteed the positioning accuracy of workpiece under the effect of holddown spring.Guide plate on the die block can guarantee the slip precision of angled-lift splits, and is very practical.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
