Abstract
The utility model discloses a bending die with an over-bending effect and relates to a stamping die. The bending die comprises an upper die holder, a lower die holder, a male die and a female die. An ejector plate is arranged in the female die, the male die is arranged on the upper surface of the lower die holder, the female die consists of two female die blocks arranged symmetrically, a fixing plate is arranged on the lower surface of the upper die holder, the female die blocks are hinged to the fixing plate through rotating shafts, a positioning block is arranged between the two female die blocks and fixedly connected to the lower surface of the upper die holder, the ejector plate is slidably connected into the positioning block by an ejector rod, the female die blocks are connected with the positioning block through rubber gaskets, two guide blocks are symmetrically arranged on two sides of the male die on the lower die holder, and bevels matched with each other are respectively arranged at positions, close to the lateral sides of the male die and corresponding to the female die blocks, of the guide blocks. The bending die with the over-bending effect has the advantages that springback of bending parts can be reduced effectively, dimension precision of the bending parts can be guaranteed, and reject ratio is lowered.
Description
Technical field
The utility model relates to a kind of diel, relates in particular to a kind of overbending bending 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, and existing bending die comprises the punch and the die of steel, and punch is descending under the drive of forcing press; Workpiece is accomplished brake forming under the acting in conjunction of punch and die, when using bending die to carry out brake forming, and the play-plastic deformation who produces in the fillet district of bool; Bool is after leaving bending die, and strain is recovered, and makes bool produce resilience; Influence the geomery of bool, even produce waste product, caused waste.
Summary of the invention
To the problem that above-mentioned prior art exists, the utility model provides a kind of overbending bending die, can effectively reduce the resilience of bool, has guaranteed the dimensional accuracy of bool, has reduced percent defective.
The technical scheme of the utility model is: a kind of overbending bending die, comprise upper bolster, die shoe, punch and die, and be provided with top board in the die; Said punch is arranged at the die shoe upper surface; Die is made up of two symmetrically arranged die pieces, and the upper bolster lower surface is provided with fixed head, and the die piece is articulated on the fixed head through rotating shaft; Be provided with locating piece between two die pieces; Locating piece is fixedly connected on the upper bolster lower surface, and top board is slidingly connected in the locating piece through push rod, and the die piece is connected with locating piece through rubber blanket; The punch bilateral symmetry is provided with two guide pads on the die shoe, and guide pad is respectively arranged with the inclined-plane that cooperatively interacts near the side and the corresponding position of die piece of punch.
As preferably, upper bolster, die shoe and locating piece all adopt the Q235 steel plate to process, and said punch adopts the GCr15 steel to process, and the side that punch is corresponding with the die piece is respectively arranged with symmetrical wedge-shaped slot.
As preferably, top board, push rod and guide pad all adopt 45 steel to process, and guide pad is fixedly connected on the die shoe upper surface through screw, and the inclined-plane of guide pad is provided with oil storage tank.
The beneficial effect of the utility model is: the die of the utility model is made up of two symmetrically arranged die pieces, and the die piece is articulated on the fixed head and through rubber blanket through rotating shaft and is connected with locating piece, when brake forming; Along with forcing press is descending, the die piece moves to the direction near punch through rotating shaft under the effect of guide pad; Flexural deformation to bool produces reinforcement, makes 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, has reduced percent defective; After bending is accomplished; Move on the upper bolster, the die piece is got back to initial position under the effect of rubber blanket, waits for crooked next time.
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 overbending bending die; Comprise upper bolster 4, die shoe 11, punch 10 and die, in the present embodiment as preferred, upper bolster 4 adopts the Q235 steel plate to process with die shoe 11; Good combination property, long service life.Punch 10 adopts the GCr15 steel to process, and intensity is high.
Be provided with top board 3 in the die, said punch 10 is arranged at die shoe 11 upper surfaces, and die is made up of two symmetrically arranged die pieces 2; Upper bolster 4 lower surfaces are provided with fixed head 9, and die piece 2 is articulated on the fixed head 9 through rotating shaft 8, are provided with locating piece 6 between two die pieces 2; In the present embodiment, as preferably, locating piece 6 adopts the Q235 steel plates to process; Locating piece 6 is fixedly connected on upper bolster 4 lower surfaces; Top board 3 is slidingly connected in the locating piece 6 through push rod 5, and as preferably, top board 3 adopts 45 steel to process with push rod 5.Die piece 2 is connected with locating piece 6 through rubber blanket 7, and in the present embodiment, as preferably, die piece 2 and locating piece 6 side in opposite directions have groove, and rubber blanket 7 is positioned at groove.Rubber blanket 7 adopts polyurethane rubber to process, and elasticity and wearability are good, long service life.Punch 10 bilateral symmetry are provided with two guide pads 1 on the die shoe 11, and as preferably, guide pad 1 adopts 45 steel to process.Guide pad 1 is respectively arranged with the inclined-plane that cooperatively interacts near the side and the die piece 2 corresponding positions of punch 10; As preferably; Guide pad 1 is fixedly connected on die shoe 11 upper surfaces through screw, and the inclined-plane of guide pad 1 is provided with oil storage tank, and is conveniently lubricated for the inclined-plane mating part; Reduce wear, prolonged the service life of the utility model.
In the present embodiment, as preferably, punch 10 and die piece 2 corresponding sides are respectively arranged with the wedge-shaped slot of symmetry, make things convenient for the overbending of bool.
