Abstract
The utility model discloses an anti-rebound bending die and relates to a stamping die. The anti-rebound bending die comprises an upper die seat, a lower die seat, a die handle, a male die and a female die, wherein the male die is fixedly connected to the upper surface of the lower die seat through a male die fixing plate; the female die consists of two symmetrical female die blocks; a fixing plate is arranged on the lower surface of the upper die seat; the female die blocks are hinged on the fixing plate through a rotating shaft; a positioning block is arranged between the two female die blocks; the positioning block is fixedly connected to the lower surface of the upper die seat; the female die blocks are connected with the positioning block through a rubber pad; two guide blocks are symmetrically arranged on the two sides of the male die on the lower die seat; inclined surfaces matched with each other are formed on the sides, near the male die, of the guide blocks and the positions corresponding to the female die blocks; and triangular reinforcing ribs are arranged on the sides, far away from the male die, of the guide blocks. The anti-rebound bending die effectively reduces rebound of a bending piece, guarantees the dimensional precision of the bending piece, reduces the rejection rate, and is very practical.
Description
Technical field
The utility model relates to a kind of diel, relates in particular to a kind of anti-rebound bending die.
Background technology
Crooked part is one of punching parts that during Modern Industry Products, automobile, electrical equipment, instrument and instrument are made, quantity is maximum.The crooked part major part adopts bending die to process, existing bending die comprises punch and the die of steel, and punch is descending under the drive of forcing press, and workpiece is completed brake forming under the acting in conjunction of punch and die, when using bending die to carry out brake forming, the play-plastic deformation who produces in the fillet district of bool, bool is after leaving bending die, and strain is recovered, make bool produce resilience, affect the geomery of bool, even produce waste product, caused waste.
Summary of the invention
For the problem that above-mentioned prior art exists, the utility model provides a kind of anti-rebound bending die, can effectively reduce the resilience of bool, has guaranteed the dimensional accuracy of bool, has reduced percent defective, and is very practical.
the technical solution of the utility model is: a kind of anti-rebound bending die, comprise upper bolster, die shoe, die shank, punch and die, described punch is fixedly connected on the die shoe upper surface by punch retainer, die is comprised of two symmetrically arranged die pieces, the upper bolster lower surface is provided with fixed head, the die piece is articulated on fixed head by rotating shaft, be provided with locating piece between two die pieces, locating piece is fixedly connected on the upper bolster lower surface, the die piece is connected with locating piece by rubber blanket, die shoe upper male mould bilateral symmetry is provided with two guide pads, guide pad is respectively arranged with near the side of punch and position corresponding to die piece the inclined-plane that cooperatively interacts, guide pad is provided with the triangle ribs away from the side of punch.
As preferably, also comprise pressing plate, pressing plate is slidably connected in locating piece, and the pressing plate upper surface is fixedly connected with makes bar, makes bar and is positioned at upper bolster and die shank, and the upper surface of die shank is stretched out in the upper end of making bar, beats bar and upper bolster and die shank matched in clearance.
As preferably, guide pad is fixedly connected on the die shoe upper surface by screw, is provided with oil storage tank on the inclined-plane of guide pad, and punch adopts the GCr15 steel to make, and the side that punch is corresponding with the die piece is respectively arranged with the wedge-shaped slot of symmetry
the beneficial effects of the utility model are: die of the present utility model is comprised of two symmetrically arranged die pieces, the die piece is articulated on fixed head and by rubber blanket by rotating shaft and is connected with locating piece, when brake forming, along with forcing press is descending, the die piece is under the effect of guide pad, move to the direction near punch by rotating shaft, flexural deformation to bool produces reinforcement, make the bool overbending, after like this bool being taken out from bending die, the elastic recoil of curvature portion material has compensated the resilience of bool two sidewalls, guaranteed the precision of bool, reduced percent defective, after bending is completed, move on upper bolster, the die piece is got back to initial position under the effect of rubber blanket, wait for next time crooked, very practical.
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 anti-rebound bending die, comprise upper bolster 5, die shoe 1, die shank 6, punch 12 and die, in the present embodiment, as preferably, upper bolster 5 and die shoe 1 adopt the Q235 steel plate to make, good combination property, long service life.Punch 12 adopts the GCr15 steel to make, and intensity is high, and is not fragile.Punch 12 is fixedly connected on die shoe 1 upper surface by punch retainer 13, die is comprised of two symmetrically arranged die pieces 3, upper bolster 5 lower surfaces are provided with fixed head 11, die piece 3 is articulated on fixed head 11 by rotating shaft 10, be provided with locating piece 8 between two die pieces 3, locating piece 8 is fixedly connected on upper bolster 5 lower surfaces, die piece 3 is connected with locating piece 8 by rubber blanket 9, in the present embodiment, as preferably, die piece 3 has groove with locating piece 8 side in opposite directions, and rubber blanket 9 is positioned at groove.Rubber blanket 9 adopts polyurethane rubber to make, and elasticity and wearability are good, long service life.Die shoe 1 upper male mould 12 bilateral symmetry are provided with two guide pads 2, guide pad 2 is respectively arranged with near the side of punch 12 and the position of die piece 3 correspondences the inclined-plane that cooperatively interacts, guide pad 2 is provided with triangle ribs 14 away from the side of punch 12, triangle ribs 14 can improve the rigidity of guide pad 2, avoid the horizontal play of guide pad 2, improved guiding accuracy.
