Abstract
The utility model is mainly concerned with a kind of diel of lithium ion battery explosion-proof piece, including upper mould, pressure roller, lower mould, burst disk installation is positioned at lower mould, if offering the groove of arterial highway both ends insertion on upper mould, pressure roller inserts in a groove, and the end bosses of pressure roller are in the surface of upper mould.The utility model causes the curve of punching press indentation to relax, and is pierced without sharp side, while simple in construction, and assembling is flexible.
Description
Technical field
The utility model is related to dynamic lithium battery production technical field, especially with a kind of punching press of lithium ion battery explosion-proof piece
Mould is relevant.
Background technology
As world energy sources is in an emergency, lithium ion battery is big with its energy density, the advantage such as service life cycle time length, quilt
Increasing technical field is of interest, particularly nowadays by the extensive use of electric automobile industry institute.Lithium ion battery applications
On electric automobile, its safety and reliability is the technical essential that everybody extremely pays close attention to.Lithium ion battery by short circuit,
High fever, under the influence of the extraneous undesirable element such as overcharging, inside battery easily produces gases at high pressure, causes battery container deformation even quick-fried
It is fried, meanwhile, external force extruding also results in lithium ion internal damage, produces severe safety accident.
So can all be designed with explosion-proof valve block on lithium ion battery substantially, the principle of explosion-proof valve block is the office on lamellar body
Portion's punching press indentation, when internal gas is concentrated, can make breakthroughs mouth at these indentations, concentrate outburst, realize exhaust.It is existing
Many modes for making explosion-proof valve indentation are to use pressing, directly go out indentation on explosion-proof valve lamellar body with sharp blade.
Compare than sharp, and in the quality monitoring management of lithium ion once having at the indentation edge that such mode can to go out
Sharp position, there will be potential safety hazard.
Therefore, the present inventor devises a kind of diel of lithium ion battery explosion-proof piece for this problem, this case by
This is produced.
Utility model content
The purpose of this utility model is to provide a kind of diel of lithium ion battery explosion-proof piece so that the song of punching press indentation
Line relaxes, and is pierced without sharp side, while simple in construction, and assembling is flexible.
To achieve the above object, the technical solution adopted in the utility model is as follows：
A kind of diel of lithium ion battery explosion-proof piece, including upper mould, pressure roller, lower mould, burst disk installation are positioned at down
Mould, if offering the groove of arterial highway both ends insertion on upper mould, pressure roller inserts in a groove, and the end bosses of pressure roller are in upper mould
Surface.
Described pressure roller include being used for interting into groove installation portion and be raised in the surface modes splenium of upper mould.
Described molding portion end is arced terminus.
Described groove is dovetail groove；Described installation portion is the wedge to match with dove tail shape.
Described groove is some.
Described lower mould, the position periphery that burst disk is placed is provided with limiting plate.
Described upper mould is arranged on ram axle.
Described lower mould is arranged on base station.
The beneficial effects of the utility model are as follows：
, can be according to practically necessary shape in the utility model by the way of upper mould and pressure roller are formed and flexibly assembled
To be assembled, while it is arced terminus in the end in molding portion, avoids the sharp edge thorn of punching press, the utility model utilizes pressure
The mode of mould, when upper and lower mould fastens, by the shape indentation of pressure roller in burst disk, realize punching press.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model preferred embodiment；
Fig. 2 is the floor map of upper mould in the utility model preferred embodiment.
Embodiment
Referring to Fig. 1 and Fig. 2, the utility model preferred embodiment is further elaborated.
A kind of diel of lithium ion battery explosion-proof piece, the part being mainly concerned with include upper mould 1, pressure roller 2, lower mould 3,
Limiting plate 4.
Upper mould 1 is mostly installed on the line shaft of punching press, with axle lower work.The lower surface of upper mould 1 has opened up some
Groove 11, the fluted 11 two insertion of institute are convenient to insert pressure roller 2.11 horizontal and vertical vertical interlaced of the present embodiment further groove is arranged
Row, the section of groove 11 is oat tail groove structure, is not fallen off after can so assembling fixed pressure roller 2.
Pressure roller 2 includes two positions, and a position is installation portion 21, is predominantly used to assemble with groove 11, using wedge shape
Block to match with oat tail groove structure.Another position is molding portion 22, and molding portion 22 is raised in the surface of mould 1, while molding portion
22 end is arced terminus, flash and sharp when can so prevent indentation punching press.
Lower mould 3 is a fixed platform, on the base station of operation.It is provided with the position both sides that burst disk 5 is installed
Limiting plate 4, when upper mould 1 declines, it is resisted against the depth that punching press is controlled on limiting plate 4.
It is main using pressure roller 2 is inserted into groove 11 from the side during utility model works, according to being actually needed,
Pressure roller 2 is installed on corresponding groove 11, because groove 11 sets relatively more, therefore can be set and be assembled into times according to actual conditions
What shape, therefore versatility is also stronger, installs burst disk 5 in place before punching press, then upper mould 1 declines, and is down to limiting plate 4
Height and position, now pressure roller 2 be stamped and formed out indentation.
Above is the utility model preferred embodiment, make that some other are simple under the utility model concept thereof
Replace and change, should all be considered as belonging to protection category of the present utility model.
