Description

A kind of stereotype grid diel

Technical field

The utility model is related to machined die field, especially a kind of stereotype grid diel.

Background technology

With the continuous popularization of battery applications, battery grid as the core component of battery, its demand and performance Require also more and more higher, most battery battery grid mostly is plate armature, the electricity of plate armature on the market at present Pond grid is deposited on the phenomenon of battery case bottom, constantly sinking with lead powder occurring that after Long-Time Service lead powder comes off Long-pending, adjacent cell grid then can lead to battery short circuit phenomenon upon the lead powder formation loop of deposition, therefore occurs in that Some special-shaped grids preventing lead powder from dropping to battery cell case bottom, but at present domestic abnormal shape battery grid forming technique from Dynamicization degree is relatively low, needs to be operated through multiple links, not only wastes time and energy, and also can increase cost of labor, produces Efficiency is low, also can cause the waste on materials'use simultaneously and make the inaccurate of precision.

Content of the invention

In order to solve the deficiencies in the prior art, the utility model provide a kind of easy to use, production efficiency is high, can reduce The stereotype grid diel of production cost.

In order to realize above-mentioned technical purpose, the technical solution of the utility model is：A kind of stereotype grid diel, described Stamping forming stereotype grid include rectangle grid plane and the bending edges located at grid plane edge, described bending edges with Grid plane junction forms bending, and described diel includes upper die and lower die, the end that described lower mould is coordinated with upper mould The circle groove supporting block edge is located on face, described groove type at least provided with the support support block of grid plane and ring Shape is corresponding with grid bending dorsal part shape, and described groove upwardly extends and is less than lower mould upper end away from the side wall of support block Face, described support block upper surface is less than lower mould upper surface, and the corresponding lower mould support block position of described upper mould is provided with rectangle Recessed structure and a circle chimb, described chimb position is corresponding with groove, described chimb shape and stereotype grid bending structure phase Corresponding, described upper mould forms forming gap after coordinating with lower mould, and described forming gap shape is identical with lead grid shape.

Described support block is more than a pair, and the pair of above support block is arranged side by side along lower mould length direction, institute It is separated by the side wall away from support block between the groove of support block edge stated, the corresponding lower mould of described upper mould at least sets There are the rectangle concave inward structure being arranged side by side and chimb more than a pair, between described chimb, leave side between the corresponding lower mould groove of receiving The gap of wall.

Described support block is rectangular configuration.

Described upper die and lower die are integral type structure.

Using above-mentioned technical scheme, the beneficial effects of the utility model are：Using upper and lower mould cooperation punching press by plane lead Grid strike out edge have bending structure shape, improve make efficiency and make precision, upper die and lower die can To need to be designed multiple molding structures to improve product punching press production capacity according to production capacity, mould is wherein descended to support by support block Grid plane, the chimb being located at the corresponding upper mould of groove supporting block edge using ring carries out punch forming product, upper mould and under The integrated structure of mould design, can be easy to later stage mould maintaining.

Specific embodiment

As shown in one of Fig. 1 to 6, the stereotype grid 1 of the utility model mould punching shaping include rectangle grid plane 11 He Located at the bending edges 12 of grid plane edge, described bending edges 12 form bending 13, institute with grid plane 11 junction The diel stated includes mould 2 and lower mould 3, at least provided with a gripper shoe on the end face that described lower mould 3 is coordinated with upper mould 2 The support block 31 of grid plane and ring are located at a circle groove 32, described groove 32 shape and the stereotype grid bending 13 supporting block edge Dorsal part shape is corresponding, and described groove 32 upwardly extends and is less than lower mould 3 upper surface 34 away from the side wall 33 of support block 31, Described support block 31 upper surface is less than lower mould 3 upper surface 34, and corresponding lower mould 3 support block 31 position of described upper mould 2 is provided with Rectangle concave inward structure 21 and a circle chimb 22, described chimb 22 position is corresponding with groove 32, described chimb 22 shape and Stereotype grid bending 13 structures are corresponding, form forming gap after described upper mould 2 and lower mould 3 cooperation, described forming gap shape Shape is identical with stereotype grid 1 shape.

When support block 31 is more than a pair, the pair of above support block 31 is arranged side by side along lower mould 3 length direction, Pass through between the described groove 32 at support block 31 edge to be separated away from the side wall 33 of support block 31, described upper mould 2 is right Mould 3 should be descended at least provided with the rectangle concave inward structure 21 being arranged side by side for more than a pair and chimb 22, between described chimb 22, leave appearance The gap of side wall 33 between lower mould 3 groove 32 of correspondence of receiving.

Preferably, described support block 31 is rectangular configuration.

In order to improve the shock strength of mould, described upper mould 2 and lower mould 3 are integral type structure, by the knot of integral type Structure designs, and is occurred using rear situation part deformation or coming off without having to worry about upper mould 2 and the long-term punching press of lower mould 3.

The foregoing describe embodiment of the present utility model, it will be appreciated by those of skill in the art that this is only to lift Example explanation, those skilled in the art, can be to this embodiment party on the premise of without departing substantially from principle of the present utility model and essence Formula makes various changes or modifications, but these changes and modification each fall within protection domain of the present utility model.
