Abstract

The utility model relates to a bending die, and discloses a bending die with a movable female die. The bending die comprises an upper die holder, a lower die holder, a die shank, a male die and a female die. The male die is fixedly connected on the upper surface of the lower die holder through a male die fixing board. The female die is composed of two symmetrically arranged female die blocks. A fixed board is arranged on the lower surface of the upper die holder, and the female die blocks are hinged onto the fixing board through rotary shafts. A locating block is arranged between the two female die blocks and fixedly connected on the lower surface of the upper die holder. The female die blocks are connected with the locating block through reset springs. Two guide blocks are symmetrically arranged on two sides of the male die on the lower die holder. Mutually matching inclined planes are arranged at positions corresponding to the female die blocks and close to the side surfaces of the male die on the guide blocks respectively, and triangular reinforcing ribs are arranged on side surfaces of the guide blocks away from the male die. By means of the bending die with the movable female die, the rebound of bending pieces can be reduced effectively, the bending piece size accuracy is guaranteed, and the rejection rate is reduced.

Description

The mobilizable bending mould of die
Technical field
The utility model relates to a kind of bending mould, relates in particular to the mobilizable bending mould of a kind of die.
Background technology
Crooked part is one of punching parts that quantity was maximum during Modern Industry Products, automobile, electrical equipment, instrument and instrument were made.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 finished 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, so that bool produces 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 die mobilizable bending mould, can effectively reduce the resilience of bool, has guaranteed the dimensional accuracy of bool, has reduced percent defective.
The technical solution of the utility model is: the mobilizable bending mould of a kind of 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 the 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 back-moving spring, die shoe upper male mould bilateral symmetry is provided with two guide pads, guide pad is respectively arranged with the inclined-plane that cooperatively interacts near side and the position corresponding to die piece of punch, and guide pad is provided with the triangle ribs away from the side of punch.
As preferably, also comprise pressing plate, pressing plate is slidingly connected in the 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 the fixed head and by back-moving spring 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, has guaranteed the precision of bool, reduced percent defective, after bending is finished, move on the upper bolster, the die piece is got back to initial position under the effect of back-moving spring, wait for next time crooked, very convenient and 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, the mobilizable bending mould of a kind of 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 the 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 back-moving spring 9, in the present embodiment, as preferably, die piece 3 has groove with locating piece 8 side in opposite directions, and back-moving spring 9 is positioned at groove.Die shoe 1 upper male mould 12 bilateral symmetry are provided with two guide pads 2, guide pad 2 is respectively arranged with the inclined-plane that cooperatively interacts near the side of punch 12 and the position of die piece 3 correspondences, 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 guide pad 2 horizontal plaies, improved guiding accuracy.
In the present embodiment, as preferably, also comprise pressing plate 4, pressing plate 4 is slidingly connected in the locating piece 8, and pressing plate 4 upper surfaces are fixedly connected with makes bar 7, makes bar 7 and is positioned at upper bolster 5 and die shank 6, the upper surface of die shank 6 is stretched out in the upper end of making bar 7, beats bar 7 and upper bolster 5 and die shank 6 matched in clearance.Pressing plate 4 can be when bending workpiece pressing, prevent that workpiece is wrinkling.
