Abstract
The invention discloses a multipurpose bending lower die. The multipurpose bending lower die comprises a lower die body threaded hole and a positioning block threaded hole. The lower die body threaded hole is of a cuboid structure. A plurality of V-shaped grooves different in size and a plurality of threaded holes are formed in the side face of the lower die body threaded hole in the axial direction. A plurality of threaded holes are further formed in the side face of the lower die body threaded hole. The positioning block threaded hole is provided with a positioning groove threaded hole and is transversely installed in the lower die body threaded hole. Under the situation that the same bending lower die is adopted, different bending angles are formed by selecting the different lower die V-shaped grooves; a positioning block moves forwards and backwards through adjusting of a bolt, different bending size requirements are met, and therefore bending forming of bus bars different in size is achieved; and the die designing and machining cost is reduced, the component machining period is shortened, and the purposes of reducing cost and improving efficiency are achieved.

It is additionally provided with some screwed hole screwed holes, described locating piece screwed hole has locating slot screwed hole, locating piece screwed hole is laterally pacified
It is contained on lower mold body screwed hole.
Described lower mold body screwed hole cross section is square structure, and each side of lower mold body screwed hole is equipped with two V grooves
Screwed hole, with two for one group, some groups of screwed hole screwed holes are in level to the screwed hole screwed hole on lower mold body screwed hole side
On the parallel side located at lower mold body screwed hole.
The width of rebate of two V grooves on described four sides of lower mold body is respectively：12mm, 16mm；8mm, 30mm；
12mm, 24mm；8mm, 20mm.
Described V groove screwed hole angle of release is 78 °.
It is connected with bolt thread hole between described locating piece screwed hole and lower mold body screwed hole, bolt thread hole and screwed hole
Screwed hole mates.
Described locating slot screw thread hole slot footpath is more than the major diameter of thread 0.5～1.5mm in bolt thread hole.
The invention has the beneficial effects as follows：
Compared with prior art, a kind of multipurpose bending lower die that the present invention provides, the feelings of mould under using same bending
Under condition, by selecting different lower mould V grooves, realize the formation at differently curved angle；By adjustment bolt come locating piece of retreating, realize
The requirement of differently curved size, it is achieved thereby that the brake forming of various different size busbar, decreases Design of Dies processing
Cost, shortens the part process-cycle, has reached cost declining, has put forward the purpose of efficiency.

Specific embodiment
Below in conjunction with accompanying drawing, technical scheme is described further, but required protection domain does not limit to
In described；
As shown in Fig. 1～5, a kind of multipurpose bending lower die that the present invention provides, including lower mold body and locating piece 2, described
Lower mold body 1 is rectangular structure, and lower mold body 1 side axial is provided with some V grooves 4 not of uniform size, and lower mold body 1 is additionally provided with side
Some screwed holes 5, described locating piece 2 has locating slot 6, and locating piece 2 is transversely mounted in lower mold body 1, and the object of the invention exists
In the production efficiency improving busbar class crooked part, reduce part processing cost, die cost, busbar is treated by locating piece 2
Rapidoprint is arranged in lower mold body 1, then carries out Bending Processing by bending system to busbar.
Described lower mold body 1 cross section is square structure, and each side of lower mold body 1 is equipped with two V grooves 4, lower mold body 1 side
Screwed hole 5 on face with two for one group, some groups of screwed holes 5 be in horizontal parallel on lower mold body 1 side, screwed hole 5 is used
In installation locating piece 2.
The width of rebate of two V grooves 4 on described 1 four sides of lower mold body is respectively：12mm, 16mm；8mm, 30mm；
12mm, 24mm；8mm, 20mm, wherein：
The width of rebate of 8mm can bend 1mm thick material；
The width of rebate of 12mm can bend 1.5mm thick material；
