Abstract

The utility model discloses a V-shaped part bending die. The V-shaped bending die comprises a punch die, a cavity die and a baseboard. The cavity die is connected with the baseboard through inner hexagonal screws and positioned by positioning pins, a top protrusion of the punch die is in an arc shape, the top of the punch die is in a V shape, both sides of the V shape are provided with a first pressing shoulder and a second pressing shoulder respectively, a first groove is arranged between the top protrusion and the first pressing shoulder, and a second groove is arranged between the top protrusion and the second pressing shoulder. According to the V-shaped part bending die, after a workpiece is finished through press forming, the finished V-shaped part cannot spring back and high precision is achieved.

Description

A kind of V-arrangement spare bending die
Technical field
The utility model relates to a kind of cold punching die of machining, particularly a kind of V-arrangement spare bending die.
Background technology
V-arrangement spare simple shape, flexural deformation is easy, but in the process of stamping die, rebound phenomenon takes place easily, and after namely V-arrangement spare was taken out from mould, when not being subjected to mould constraint, interior angle can become greatly, has had a strong impact on precision.
The utility model content
For solving the problems of the technologies described above, it is a kind of simple in structure that the utility model provides, the V-arrangement spare bending die that no rebound phenomenon took place after the punching press of V-arrangement spare was finished.
For achieving the above object, the technical solution of the utility model is: a kind of V-arrangement spare bending die, comprise punch, die and base plate, be connected by soket head cap screw between die and the base plate and locate with alignment pin, the top ledge of punch is circular arc, and the top of punch is V-shaped, and the V-arrangement both sides are respectively arranged with first binder shoulder and second binder shoulder, be provided with first groove between top ledge and first binder shoulder, be provided with second groove between top ledge and second binder shoulder.
The beneficial effects of the utility model are: after the workpiece punching press was finished, punch left, and V-arrangement spare does not have resilience, the precision height.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: punch 1, die 2, base plate 3, soket head cap screw 4, alignment pin 5, top ledge 6, first binder shoulder, 71, second binder shoulder, 72, first groove 81, second groove 82.
The specific embodiment
Below in conjunction with accompanying drawing, and in conjunction with the embodiments, the utility model is described further.
Embodiment:
As shown in Figure 1, a kind of V-arrangement spare bending die, comprise punch 1, die 2 and base plate 3, be connected by soket head cap screw 4 between die 2 and the base plate 3 and with alignment pin 5 location, the top ledge 6 of punch 1 is circular arc, and the top of punch 1 is V-shaped, and the V-arrangement both sides are respectively arranged with first binder shoulder, 71 and second binder shoulder 72, be provided with first groove 81 between top ledge 6 and first binder shoulder 71, be provided with second groove 82 between top ledge 6 and second binder shoulder 72.
Operation principle of the present utility model is: the top ledge 6 of punch 1 is circular arc, top ledge 6 and first binder shoulder 71, be respectively equipped with first groove 81 and second groove 82 between second binder shoulder 72, when punching press, because there is certain clearance in the V-arrangement face of workpiece and punch 1, the power that makes punch 1 produce concentrates on bending deformation area, strengthen the deformation extent of deformed area, thereby reduce resilience, in addition, by the V-arrangement both sides at punch 1 first binder shoulder, 71 and second binder shoulder 72 is set respectively, in punching course, can pressurize to V-arrangement spare both ends, change the stress state of deformed area, make bending deformation area all be in compressive stress state from inside to outside, further reduce resilience.
