Technical field
The utility model relates to mould applications more particularly to a kind of battery steel shell to stretch cavity plate.
Background technique
Lithium ion battery is a kind of rechargeable battery, it relies primarily on lithium ion, and movement carrys out work between a positive electrode and a negative electrode.
In charge and discharge process, Li+ insertion and deintercalation back and forth between two electrodes: when rechargable battery, Li+ is from positive deintercalation, by electricity
It solves matter and is embedded in cathode, cathode is in lithium-rich state；It is then opposite when electric discharge.Since lithium ion battery is with small in size, light-weight, electric
The features such as strong, environmentally protective is measured, is widely used in industrial production and daily life.
Battery steel shell is the important component of lithium ion battery.Currently, battery steel shell in process of production, need by
Stretching process opens up as shown in Figure 1, stretching the structural schematic diagram of cavity plate for existing battery steel shell in 11 upper end of cavity plate ontology
The targeting port 12 for having had positioning and guiding to act on, the bore of the targeting port 12 from top to bottom successively successively decreases, and cavity plate ontology 11 is located at
The angle between inner wall and axis at targeting port 12 is 45 °, such structure design, so that workpiece enters the time of tension type chamber
Shorter, Material shrinkage excessive velocities, workpiece deformation has little time to obtain the response of material, easily generates wrinkle in the oral area of workpiece, makes
It is high to obtain defect rate, for this purpose, flanging set 14 need to be installed additional outside jumper bar 13 when stretching, after such mode, although
Workpiece oral area generates wrinkle phenomenon and is reduced, but its defect rate is still higher, is badly in need of solving as a result,.
Utility model content
The purpose of this utility model is that in view of the above-mentioned problems, providing a kind of battery steel shell stretches cavity plate, it is existing to solve
When battery steel shell stretches cavity plate stretching, wrinkle, the high problem of defect rate easily are generated in workpiece oral area.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of battery steel shell stretches cavity plate, including cavity plate ontology, is provided with tension type chamber, and cavity plate sheet on the cavity plate ontology
Top on body positioned at tension type chamber has been provided with the targeting port that positioning and guiding acts on, and the bore of the targeting port is from top to bottom successively
Successively decrease, and the lower end port of targeting port is connected with tension type chamber, the cavity plate ontology be located at the inner wall at targeting port by up to
Lower inward slant, and the angle that cavity plate ontology is located at the inner wall at targeting port and stretches between mold cavity axis is 20 °~25 °.
As a kind of preferred embodiment of the utility model, the cavity plate ontology is located at inner wall and tension type chamber at targeting port
Angle between axis is 22.5 °.
As a kind of preferred embodiment of the utility model, the tension type chamber includes the stretch section on top and the outlet of lower part
Section, the stretch section with stretching mold cavity axis it is parallel, the outlet section is from top to bottom inclined outwardly, and outlet section with it is tension type
Angle between cavity axis is 4 °~6 °.
As a kind of preferred embodiment of the utility model, the outlet section and the angle stretched between mold cavity axis are 5 °.
As a kind of preferred embodiment of the utility model, the cavity plate ontology is carbide matrix.
The beneficial effects of the utility model are, a kind of cavity plate ontology that battery steel shell stretches cavity plate is located at targeting port
Inner wall and stretch mold cavity axis between angle be 20 °~25 °, thus increase workpiece enter tension type chamber distance, prolong
Entry time is grown, so that workpiece has the process of a gradual change, the deformation of material can be responded adequately, to avoid work
Part oral area generates wrinkle, and without using flanging set, enormously simplifies structure.
