Abstract
The utility model discloses a double-wedge mechanism for a punching die, and relates to die equipment. The double-wedge mechanism comprises an upper die base, a lower die base and male dies, wherein a stop dog is arranged on the lower die base; two inclined sliding blocks are symmetrically arranged on two sides of the stop dog; a guide plate is arranged between each inclined sliding block and the lower die base and is provided with a chute; the inclined sliding blocks can slide along the chutes; inclined planes of the two inclined sliding blocks are oppositely arranged; a resetting mechanism and a limiting mechanism are arranged in each inclined sliding block; wedges are arranged on the upper die base and are opposite to the stop dog; inclined planes which are matched with the inclined sliding blocks are respectively arranged on two side surfaces of each wedge; the male dies are arranged on side surfaces, which are far away from the stop dog, of the inclined sliding blocks; and rubber pressing pieces are sleeved on the male dies. By the double-wedge mechanism for the punching die, the strength and the rigidity of the dies are improved, the service lives of the dies are prolonged, side holes of two workpieces can be formed at a time, production rate and the accuracy of a product are improved, and the double-wedge mechanism is quite practical.
Description
Technical field
The utility model relates to a kind of die apparatus, relates in particular to a kind of stamping die Double Oblique Wedge mechanism.
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 this mould is horizontally disposed with, and need be placed in towards the workpiece of side opening on the die, and vertical punch moves downward under the drive of forcing press; Accomplish the moulding of side opening, the poor rigidity of existing cantilevered perforating die is easy to die is thrust when stamping-out; Need to shut down and change die, reduced operating efficiency, improved processing cost; And existing cantilevered perforating die can only a workpiece of once-forming side opening, productivity ratio is low.
Summary of the invention
Problem to above-mentioned prior art existence; The utility model provides a kind of stamping die Double Oblique Wedge mechanism; Improve the strength and stiffness of mould, prolonged the service life of mould, and side opening that can two workpiece of one-shot forming; Improved the precision of productivity ratio and product, very practical.
The technical scheme of the utility model is: a kind of stamping die Double Oblique Wedge mechanism, comprise upper bolster, die shoe and punch, and die shoe is provided with block; 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 is provided with 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; Punch is arranged at the side of angled-lift splits away from block, is socketed with rubber press on the punch.
As preferably, said punch is a stairstepping, and punch is fixedly connected on the side of angled-lift splits away from block through punch retainer.
As preferably; The bottom surface of angled-lift splits has half groove; The opening of half groove is positioned at the side of angled-lift splits away from block, and along continuous straight runs is provided with the screw that resets in half groove, is socketed with back-moving spring on the screw that resets; 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 effect of the utility model is: the punch of the 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 the intensity and the height of mould; Make die be difficult for thrusting, prolonged the service life of mould.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, accomplishes the punching of both sides workpiece simultaneously, has improved productivity ratio, has reduced processing cost.Rubber press can workpiece pressing when moulding, guarantees the flatness and the surface quality of workpiece, prevents that the workpiece vault is curved wrinkling, very practical.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As a kind of embodiment of the utility model, as shown in Figure 1, a kind of stamping die Double Oblique Wedge mechanism; Comprise upper bolster, die shoe 11 and punch 3, die shoe 11 is provided with block 1, and 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 is provided with in opposite directions, is 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, and the opening of half groove is positioned at the side of angled-lift splits 5 away from block 1; Along continuous straight runs is provided with the screw 8 that resets in half groove; Resetting is socketed with back-moving spring 9 on the screw 8, is provided with postive stop baffle 10 near the opening of half groove and with the screw 8 corresponding positions that reset on the guide plate 2, and the end face of postive stop baffle 10 is lower than the bottom surface of half groove.Be provided with wedge 6 with block 1 corresponding position on the upper bolster, wedge 6 two sides are respectively arranged with the inclined-plane that cooperates with angled-lift splits 5; Punch 3 is arranged at the side of angled-lift splits 5 away from block 1, and die is arranged at punch 3 next doors, is socketed with rubber press 7 on the punch 3, and rubber press 7 can workpiece pressing when moulding, guarantees the flatness and the surface quality of workpiece, prevents that the workpiece vault is curved wrinkling.
In the present embodiment, as preferably, said punch 3 is a stairstepping, has improved the strength and stiffness of punch 3.Punch 3 is fixedly connected on the side of angled-lift splits 5 away from block 1 through punch retainer 4.
The course of work of the utility model is following: when stamping-out, upper bolster is descending, and 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; Accomplish 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 acting in conjunction of reset screw 8 upper reset springs 9, block 1 and postive stop baffle 10, wait for stamping-out next time.
The above is merely a kind of embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and obvious mode of texturing etc., all should be included within the protection domain of the utility model.
