Abstract

The utility model discloses a V-shaped exquisite bending die, and relates to a stamping die. The V-shaped exquisite bending die comprises an upper die base, a lower die base and a die shank, wherein a male die is arranged on the lower surface of the upper die base; a V-shaped bulge is arranged on the lower end surface of the male die; a support is arranged on the upper surface, corresponding to the male die, of the lower die base; movable female dies are hinged with the support through a rotating shaft; the rotating shaft can glide vertically relative to the support; support seats are arranged on two sides of the upper surface of the lower die base respectively; one end, far from the rotating shaft, of the movable female die, is connected with a corresponding support seat in an overlapping manner; a jacking rod is arranged in a position corresponding to the rotating shaft on the lower die base and can move relative to the lower die base; a return spring is arranged at the lower end of the jacking rod; and when the rotating shaft is located at a peak on the support, the two movable female dies are located in horizontal positions. According to the utility model, during bending processing, a blank cannot slip relative to the female dies, the precision of relative positions of holes in the workpiece is high, and a narrow strip-shaped workpiece can be placed on the V-shaped exquisite bending die stably, so that the quality of the workpiece is improved, and the V-shaped exquisite bending die is very practical.

Description

The curved mould of V-type essence
Technical field
The utility model relates to a kind of diel, relates in particular to the curved mould of a kind of V-type essence.
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.Its principal mode has: V-arrangement, U-shaped, Z-shaped, crimp and other complex-shaped parts, the crooked part major part is to adopt bending die to carry out bending forming.Existing bending die comprises punch and die, and punch is descending under the drive of forcing press, and workpiece is completed bending forming under the acting in conjunction of punch and die.In actual production; usually need to process bool with holes; general manufacturing process is first punching on workpiece; then the workpiece with hole punch is crooked; existing Bending Die is fixed, when bending machining, and the relative die slippage of workpiece meeting; cause the hole displacement on workpiece, be not suitable for the demanding bool processing of the relative positional accuracy in hole.Have larger die hole on existing bending die in addition, long narrow bar-shaped workpieces is difficult for keeping steady on existing bending die, affects the workpiece crudy.
Summary of the invention
Problem for above-mentioned prior art existence; the utility model provides a kind of V-type essence curved mould; not die slippage relatively of blank during bending machining; on workpiece, the relative positional accuracy in hole is high; long narrow bar-shaped workpieces can steadily be placed on the utility model; improved workpiece quality, very practical.
the technical solution of the utility model is: the curved mould of a kind of V-type essence, comprise upper bolster, die shoe and die shank, the upper bolster lower surface is provided with punch, described punch lower surface is provided with the V-arrangement projection, the position that the die shoe upper surface is corresponding with punch is provided with support, the support both sides are respectively arranged with movable matrix, movable matrix is hinged by rotating shaft and support, vertically support slip relatively of rotating shaft, die shoe upper surface both sides are respectively arranged with supporting base, movable matrix is overlapped on corresponding supporting base away from an end of rotating shaft, position corresponding with rotating shaft on die shoe is provided with push rod, push rod can move relative to die shoe, the push rod lower end is provided with back-moving spring, when rotating shaft is positioned on support peak, two movable matrixes are positioned at horizontal level.
As preferably, described upper bolster and die shoe adopt the Q235 steel to make, and die shank adopts 45 steel to make, and the upper bolster lower surface has groove, and punch is installed in groove, is provided with stop pin between punch and upper bolster.
As preferably, V-arrangement projection and punch are one-body molded, and supporting base is connected with die shoe by screw, is provided with stop pin between supporting base and die shoe, is provided with location-plate on movable matrix.
The beneficial effects of the utility model are: die of the present utility model is movable matrix; blank with hole punch when crooked is placed on movable matrix; then upper bolster moves down; movable matrix rotates under the effect of punch; complete bending machining, blank contacts with movable matrix all the time in BENDING PROCESS, not movable matrix slippage relatively; therefore the Kong Buhui displacement on blank, the hole relative positional accuracy of bool is high.Processing the first two movable matrix is horizontal, and movable matrix is a plane, and the above does not have die hole, and long narrow bar-shaped workpieces can steadily be placed, and has improved the crudy of workpiece, and is very practical.
Description of drawings
Fig. 1 is structural representation of the present utility model.
