Abstract
The utility model discloses a special puncher capable of obtaining products with standard and constant sizes. The special puncher comprises an upper module and a lower module which are connected through a punching support, at most five punching tubes are fixed on the lower surface of the upper module, and punching holes corresponding to the punching tubes are formed on the upper surface of the lower module. The special puncher can punch a plurality of round holes in a time, which have the same aperture and pitch.
Description
Technical field
The utility model lithium ion pole piece manufacture field specifically, relates to a kind of lamination mode pole piece circular hole processing card punch that is applied to lithium ion pole piece porous processing.
Background technology
In the lithium ion battery manufacturing industry, adopt the less of lamination mode, because the particularity of battery process, require just can reach requirement after the stack of multilayer pole piece, consistency to circular hole on the product is higher, and is bigger as the offset of every layer of pole piece circular hole, and product is had great influence.After adopting the stack of lamination mode pole piece, there is error the circular hole position that processes on pole piece, to the product quality influence greatly.
The utility model content
Problem to be solved in the utility model is under the process condition that guarantees existing essential monolithic processing pole piece circular hole, to provide a kind of special-purpose punching device that can access the size constancy product of standard.
The utility model special-purpose punching device upper module is connected by the punching press pillar with lower module, it is characterized in that, described upper module lower surface is fixed to many five impact tubes, and the lower module upper surface is provided with the punching hole corresponding with described impact tube respectively.
The utility model has following beneficial effect compared with prior art:
1. but a plurality of circular holes of disposable punching press.
2. aperture size is stable, consistency is high.
3. different model is remodeled fast, and operating process is convenient and simple, the production efficiency height.
Description of drawings
Fig. 1 is the utility model structural representation.
Finished product after Fig. 2 processes by special-purpose punching device.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, upper module 1 is connected by the punching press pillar with lower module 2, and described upper module lower surface is fixed to many five impact tubes 3, and the lower module upper surface is provided with the punching hole corresponding with described impact tube 4 respectively.The utility model can a plurality of circular holes of disposable punching press, and distance can be just the same between aperture and the Kong Yukong.
In process of production, the semi-finished product working (finishing) area is 30mm * 20mm, requires the position of operator in regulation, 3 equidistant circular holes of punching press, and circular hole laterally consistent with fore-and-aft distance could guarantee (as Fig. 2) production requirement.Use a punching press of the utility model, just can reach production requirement.Immutable between the utility model punching hole distance, but the diameter of hole can be changed along with the thickness of product.
The situation of the above only is that utility model is described, and is not that the utility model scope is limited, and under the prerequisite that does not break away from method for designing, can also be increased to 5 punching hole at most according to production requirement.
