Description
Technical field
The utility model relates to mould applications more particularly to a kind of battery steel shell blanking dies.
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
Blanking process, as shown in Figure 1, being the structural schematic diagram of existing battery steel shell blanking die, which includes cope plate 11, lower die
Plate 12, punch-pin 13, cavity plate 14, blank holder 15, blanking upper slitter 16, blanking cut 17, guide sleeve 18 and guide post 19, and blanking upper slitter 16 is solid
Due on cope plate 11, blanking cuts 17 and is fixed in lower template 12, when which molds, it is desirable that blanking upper slitter 16 and blanking
The position for cutting 17 must be accurate, otherwise unilateral gap of the two in diametrical direction can damage mould no more than 0.003mm
Tool, however, guide post 19 is installed in lower template 12 since guide sleeve 18 is installed on cope plate 11, only in molding, guide post
19, guide sleeve 18 can just play a role, and in 11 downlink of cope plate, precision only relies on the precision of punching machine itself to guarantee,
And the precision of punching machine itself is often below the precision of 19 guide sleeve 18 of guide post, but its active force is far longer than 19 guide sleeve 18 of guide post again
Detent force, therefore, punching machine can generate certain traction action when driving 11 downlink of cope plate to 19 guide sleeve 18 of guide post, it is long this with
Past, guiding accuracy is difficult to ensure, and then is difficult to ensure that blanking upper slitter 16 and blanking cut 17 position precision, to easily cause mould
Tool damage 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, a kind of battery steel shell blanking die is provided, to solve existing electricity
Pond steel shell blanking die is difficult to ensure the position precision that blanking upper slitter and blanking are cut, thus the problem of easily causing burn failure.
The purpose of this utility model is to be achieved through the following technical solutions:
Under a kind of battery steel shell blanking die, including cope plate, lower template, punch-pin, cavity plate, blank holder, blanking upper slitter, blanking
Knife and guidance set, the punch-pin, blank holder are fixed on cope plate, and the blanking cuts the upper end for being fixed on cavity plate, described
Guidance set includes the guide post being fixed in lower template and the guide sleeve being connected on guide post that can be moved up and down, and is connected on the guide sleeve
It is connected to edge of a knife fixed plate, the edge of a knife fixed plate is located at the top that blanking is cut, and it is solid that the blanking upper slitter is fixedly connected on the edge of a knife
On fixed board.
As a kind of preferred embodiment of the utility model, the guidance set is 4, is distributed in the quadrangle of lower template.
As a kind of preferred embodiment of the utility model, ball sleeve is provided between the guide post and guide sleeve.
As a kind of preferred embodiment of the utility model, the top of the guide post has been fixedly connected with the limit of position-limiting action
Part.
As a kind of preferred embodiment of the utility model, stripper, the stripper position are fixedly connected on the guide sleeve
Discharging set is fixedly connected in the lower part of edge of a knife fixed plate, and on stripper, the discharging set is located at the lower section of blanking upper slitter.
The beneficial effects of the utility model are, a kind of guide post of battery steel shell blanking die, blanking upper slitter, is fallen guide sleeve
Material is cut in lower template, so that the position precision that blanking upper slitter, blanking are cut is not influenced by the precision of punching machine itself, together
When will not generate traction action to guide post guide sleeve when punching machine being made to drive cope plate downlink, and then ensure that the positioning of guide post guide sleeve
Precision is unaffected, to ensure that the position precision that blanking upper slitter, blanking are cut, so that the two is unilateral in diametrical direction
Gap does not exceed 0.003mm, effectively extends the service life of battery steel shell blanking die.
