Abstract
The utility model discloses a resilience reducing device for a bending die, and relates to a die device. The resilience reducing device for the bending die comprises a lower die holder, a convex die and a concave die, wherein the concave die is composed of two concave die blocks arranged symmetrically; an ejector plate is arranged in the concave die; each concave die block comprises a fixed block and a movable block; each fixed block is fixedly connected on the lower die holder, while each movable block is connected with the fixed block and capable of moving relatively to the fixed block along the horizontal direction; a rubber plate is arranged between the fixed block and the movable block; a positioning pin is detachably connected on the ejector plate; and a blind hole matched with the positioning pin is formed in the lower surface of the convex die. The resilience reducing device for the bending die is capable of effectively reducing the resilience of a bent piece, thereby guaranteeing the dimension accuracy of the bent piece and reducing the rejection rate.
Description
Technical field
The utility model relates to a kind of die apparatus, relates in particular to a kind of bending die and reduces resilient mounting.
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 bending die to reduce resilient mounting, 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 bending die reduces resilient mounting, comprises die shoe, punch and die, and die is made up of two symmetrically arranged die pieces; Be provided with top board in the die; Said die piece is made up of fixed block and movable block, and fixed block is fixedly connected on the die shoe, and movable block is connected with fixed block; And but along continuous straight runs relative fixed piece moves, and is provided with rubber slab between fixed block and the movable block; Be removably connected with alignment pin on the top board, the punch lower surface has the blind hole that cooperates with alignment pin.
As preferably, said movable block is connected with fixed block through screw, and along continuous straight runs has through hole on the fixed block, and screw passes through hole and is connected with movable block, and the nail body of screw can slide in through hole.
As preferably, said rubber slab adopts polyurethane rubber to process, and die shoe, fixed block, movable block and top board adopt the Q235 steel plate to process, and said punch adopts the GCr15 steel to process.
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 made up of fixed block and movable block, but movable block along continuous straight runs relative fixed piece moves; Be provided with rubber slab between movable block and the fixed block, when brake forming, movable block is under the effect of rubber reaction force; 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, the convenient porose workpiece of alignment pin and blind hole is located when moulding, has improved the precision of product.
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 bending die reduces resilient mounting, comprises die shoe 1, punch 5 and die 2; Die 2 is made up of two symmetrically arranged die pieces, is provided with top board 6 in the die 2, and said die piece is made up of fixed block and movable block; Fixed block is fixedly connected on the die shoe 1, and movable block is connected with fixed block, but and along continuous straight runs relative fixed piece move; In the present embodiment, as preferably, said movable block is connected with fixed block through screw 8; Along continuous straight runs has through hole on the fixed block, and screw 8 passes through hole and is connected with movable block, and the nail body of screw 8 can slide in through hole.Be provided with rubber slab 7 between fixed block and the movable block; Be removably connected with alignment pin 3 on the top board 6, in the present embodiment, have through hole on the top board 6, alignment pin 3 is connected in this through hole, can certainly adopt other to removably connect, such as being threaded etc.Punch 5 lower surfaces have the blind hole 4 that cooperates with alignment pin 3, and alignment pin 3 is located when moulding with blind hole 4 convenient porose workpiece.
In the present embodiment, as preferably, said rubber slab 7 adopts polyurethane rubbers to process, and elasticity and wearability are good.Die shoe 1, fixed block, movable block and top board 6 adopt the Q235 steel plate to process good combination property, long service life.Said punch 5 adopts the GCr15 steel to process, and intensity is high, and wearability is good.
