Abstract
The utility model discloses a double-wedge mechanism for a cold-punched die, relating to die equipment. The double-wedge mechanism comprises an upper die holder, a lower die holder and a male die, wherein the lower die holder is provided with a stop dog; the two sides of the stop dog are symmetrically provided with two oblique slide blocks; a guide plate is arranged between the oblique slide blocks and the lower die holder; the guide plate is provided with a sliding chute; the oblique sliding blocks can slide along the sliding chute; the oblique planes of the two oblique slide blocks are arranged oppositely; the oblique slide blocks are respectively internally provided with a resetting mechanism and a limiting mechanism; the part of the upper die holder corresponding to the stop dog is provided with wedges; the two side faces of the wedges are respectively provided with an oblique plane matched with the oblique slide block; the two oblique planes of the wedges are respectively provided with an anti-wearing cushion block; and the male die is arranged on the side faces of the oblique slide blocks far away from the stop dog. With the double-wedge mechanism for the cold-punched die disclosed by the utility model, the strength and rigidity of the die are improved, and the service life of the die is prolonged; and the side holes of two work pieces can be formed once, so that production rate and product precision are improved.
Description
Technical field
The utility model relates to a kind of die apparatus, relates in particular to a kind of cold-punching mould Double Oblique Wedge mechanism.
Background technology
In punching production; usually need to be at the jatharapanvartanasana workpiece (such as cylindrical member; box part; large-scale covering etc.) punching on the sidewall; generally be to use cantilever type punching die; the die of this mould is horizontally disposed with; the workpiece that needs is rushed side opening is placed on the die; vertical punch moves downward under the drive of forcing press; finish the moulding of side opening; the poor rigidity of existing cantilever type punching die is easy to die is thrust when stamping-out, needs to shut down the replacing die; reduced operating efficiency; improved processing cost, and the side opening that existing cantilever type punching die can only a workpiece of once-forming, productivity ratio is low.
Summary of the invention
Problem for above-mentioned prior art existence, the utility model provides a kind of cold-punching mould Double Oblique Wedge mechanism, has improved the strength and stiffness of mould, has prolonged the mold use life-span, and side opening that can two workpiece of one-shot forming has improved the precision of productivity ratio and product.
The technical solution of the utility model is: a kind of cold-punching mould Double Oblique Wedge mechanism, comprise upper bolster, die shoe and punch, be provided with block on the die shoe, the block bilateral symmetry is provided with two angled-lift splitses, be provided with guide plate between angled-lift splits and the die shoe, have chute on the guide plate, angled-lift splits can slide along chute, the inclined-plane of two angled-lift splitses arranges in opposite directions, be provided with resetting-mechanism and position-limit mechanism in the angled-lift splits, position corresponding with block on the upper bolster is provided with wedge, and the wedge two sides are respectively arranged with the inclined-plane that cooperates with angled-lift splits, is respectively arranged with the abrasionproof cushion block on two inclined-planes of wedge; Punch is arranged at angled-lift splits away from the side of block.
As preferably, described punch is stairstepping, and punch is fixedly connected on angled-lift splits away from the side of block by punch retainer, and described abrasionproof cushion block adopts polyurethane rubber to make.
As preferably, the bottom surface of angled-lift splits has half groove, the opening of half groove is positioned at angled-lift splits away from the side of block, along continuous straight runs is provided with the screw that resets in half groove, reset and be socketed with the rubber blanket that resets on the screw, be provided with postive stop baffle near the opening of half groove and the position corresponding with the screw that resets on the guide plate, the end face of postive stop baffle is lower than the bottom surface of half groove.
The beneficial effects of the utility model are: punch of the present utility model is horizontally disposed with, corresponding die can vertically be fixed on above the die shoe, has avoided the setting of die cantilever, has improved intensity and the height of mould, make die be difficult for thrusting, prolonged the mold use life-span.When stamping-out, upper bolster is descending, and the angled-lift splits of wedge and both sides contacts, and angled-lift splits is moved horizontally simultaneously, finishes simultaneously the punching of both sides workpiece, has improved productivity ratio, has reduced processing cost.The abrasionproof cushion block can prevent the wedge wearing and tearing, prolongs the service life of wedge.
Description of drawings
Fig. 1 is 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 cold-punching mould Double Oblique Wedge mechanism, comprise upper bolster, die shoe 11 and punch 3, be provided with block 1 on the die shoe 11, block 1 bilateral symmetry is provided with two angled-lift splitses 5, be provided with guide plate 2 between angled-lift splits 5 and the die shoe 11, have chute on the guide plate 2, angled-lift splits 5 can slide along chute, the inclined-plane of two angled-lift splitses 5 arranges in opposite directions, be provided with resetting-mechanism and position-limit mechanism in the angled-lift splits 5, in the present embodiment, as preferably, the bottom surface of angled-lift splits 5 has half groove, the opening of half groove is positioned at angled-lift splits 5 away from the side of block 1, and along continuous straight runs is provided with the screw 8 that resets in half groove, is socketed with the rubber blanket 9 that resets on the screw 8 that resets, be provided with postive stop baffle 10 near the opening of half groove and the position corresponding with the screw 8 of resetting on the guide plate 2, the end face of postive stop baffle 10 is lower than the bottom surface of half groove.Position corresponding with block 1 on the upper bolster is provided with wedge 6, wedge 6 two sides are respectively arranged with the inclined-plane that cooperates with angled-lift splits 5, be respectively arranged with abrasionproof cushion block 7 on two inclined-planes of wedge 6, abrasionproof cushion block 7 can prevent wedge 6 wearing and tearing, prolongs the service life of wedge 6, in the present embodiment, as preferably, described abrasionproof cushion block 7 adopts polyurethane rubber to make, and wearability is good, long service life.Punch 3 is arranged at angled-lift splits 5 away from the side of block 1, and die is arranged at punch 3 next doors.
In the present embodiment, as preferably, described punch 3 is stairstepping, has improved the strength and stiffness of punch 3.Punch 3 is fixedly connected on angled-lift splits 5 away from the side of block 1 by punch retainer 4.
The course of work of the present utility model is as follows: when stamping-out, upper bolster is descending, the angled-lift splits 5 of 6 two inclined-planes of wedge and both sides contacts, angled-lift splits 5 is moved horizontally to the direction near die simultaneously, finish the punching of two workpiece, forcing press arrives after bottom dead center up, moves on the upper bolster, angled-lift splits 5 is got back to initial position under the screw 8 that resets resets the acting in conjunction of rubber blanket 9, block 1 and postive stop baffle 10, wait for next time stamping-out.
