Description
Technical field
The utility model relates to a kind of diel, relates in particular to a kind of anti-resilience 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, existing bending die comprises the 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, make bool produce resilience, influence the geomery of bool, even produce waste product, caused waste.
Summary of the invention
At the problem that above-mentioned prior art exists, the utility model provides a kind of anti-resilience overbending bending die, 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: a kind of anti-resilience overbending bending die, comprise upper bolster, die shoe, punch and die, be provided with top board in the die, described punch is arranged at the die shoe upper surface, die is made up 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, the die piece is provided with the bar shaped projection away from the sidewall of locating piece, locating piece is fixedly connected on the upper bolster lower surface, top board is slidingly connected in the locating piece by push rod, the die piece is connected with locating piece by rubber blanket, and 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 of punch and the position of die piece correspondence.
As preferably, upper bolster, die shoe and locating piece all adopt the Q235 steel plate to make, and described punch adopts the GCr15 steel to make, 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 make, and guide pad is fixedly connected on the die shoe upper surface by screw, and the inclined-plane of guide pad is provided with oil storage tank.
The beneficial effects of the utility model are: die of the present utility model is made up of two symmetrically arranged die pieces, the die piece is articulated on the 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 direction by rotating shaft near punch, 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, has 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 rubber blanket, waits for crooked next time.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
