When the V-type precise bending die is used for bending machining, a blank is free from sliding relatively to the female die, so that the precision of relative positions of holes on a workpiece is high, a narrow elongated workpiece can be stably placed on the V-type precise bending die, and the quality of the workpiece can be improved.
Description
Technical field
The utility model relates to a kind of diel, relates in particular to the smart curved mould of a kind of V-type.
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.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 finished 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 the workpiece, be not suitable for the demanding bool processing of the relative positional accuracy in hole.Have larger die hole on the existing bending die in addition, long narrow bar-shaped workpieces is difficult for keeping steady at 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 smart curved mould, not relatively die slippage of blank during bending machining, and the relative positional accuracy in hole is high on the workpiece; long narrow bar-shaped workpieces can steadily be placed on the utility model, has improved workpiece quality.
The technical solution of the utility model is: the smart curved mould of a kind of V-type, 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 relatively support slip of rotating shaft, die shoe upper surface both sides are respectively arranged with supporting base, movable matrix is overlapped on the corresponding supporting base away from an end of rotating shaft, position corresponding with rotating shaft on the die shoe is provided with push rod, and push rod can move relative to die shoe, and the push rod lower end is provided with the rubber blanket that resets, when rotating shaft was positioned on the support peak, two movable matrixes were 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 the groove, is provided with stop pin between punch and the 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 the die shoe, is provided with location-plate on the 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 the movable matrix; then upper bolster moves down; movable matrix rotates under the effect of punch; finish bending machining, blank contacts with movable matrix all the time in BENDING PROCESS, not relatively movable matrix slippage; therefore the Kong Buhui displacement on the 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 convenient and practical.
Description of drawings
Fig. 1 is structural representation of the present utility model.
