Description

Tool jig for bending lithium battery tab

Technical Field

The utility model relates to the field of lithium battery processing equipment, in particular to a tool jig for bending a lithium battery tab.

Background

Along with the popularization of electric vehicles, the demand on batteries is more and more high, further requirements on battery endurance and energy density are provided, in order to improve the capacity and the energy density of a battery core, the welding technology of a battery core lug is improved, the original direct welding process is improved into a folding welding process, the welding mode of an inner lug is optimized under the same overall dimension, the inner space is saved, the energy density is improved, and the material cost is saved.

The utmost point ear that the utmost point ear book welding technology corresponds need bend the processing, and the mode that present utmost point ear book welding process corresponds is welded utmost point ear and electric core earlier together, turns over through the instrument is manual, and the instrument is manual to be turned over a book, and the pole piece is taken up easily, causes the electric core short circuit, has increaseed electric core safety risk, in order to avoid above problem, needs to bend the processing to utmost point ear in advance, and at present, there is not the frock structure of handling to the utmost point ear is bent specially.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects in the prior art and provides a tool jig for bending a lithium battery tab.

In order to achieve the purpose, the technical scheme adopted by the utility model is as follows:

a tool jig for bending a lithium battery tab comprises an upper punching assembly and a lower punching assembly which are opposite to each other, wherein the upper punching assembly comprises a top plate and a punch connected with the top plate; the lower punching assembly comprises a bottom plate and a base connected with the bottom plate;

the end face of the punch is provided with an upper punching hole, the end face of the base is provided with a lower punching hole, and the upper punching hole and the lower punching hole are consistent in shape and are mutually matched.

Furthermore, the upper punching port and the lower punching port are Z-shaped.

Further, the base is made of a magnet.

Further, the punch is fixedly connected with the top plate through a bolt.

Further, the bottom plate and the base are integrally formed.

Further, the top plate is connected with a lifting driving piece.

Furthermore, a plurality of fixing holes are formed in four corners of the bottom plate.

The utility model has the beneficial effects that: when the structure is used, the lug is placed at the lower punching port of the base, the lifting driving piece drives the punching head to move downwards, the upper punching port of the punching head and the lower punching port of the base form a bent product relative to the extruded lug after the extruded lug is bent, the bent lug is welded with the electric core in a matching way, the lug is optimized to be connected with the electric core by changing the welding mode of the lug, the process space is saved, the manual folding mode of original personnel is also changed, and the risk is reduced.

Detailed Description

As shown in fig. 1 to 3, the tooling jig for bending the lithium battery tab comprises an upper punching assembly and a lower punching assembly which are opposite to each other, wherein the upper punching assembly comprises a top plate 1 and a punch 2 connected with the top plate 1, the punch 2 is fixedly connected with the top plate 1 through a bolt 3, and the top plate 1 is connected with a lifting driving piece;

further, lower punching press subassembly includes bottom plate 4 and is connected base 5 with bottom plate 4, is equipped with last punching press mouth 6 on the terminal surface of drift 2, is equipped with down punching press mouth 7 on the terminal surface of base 5, and last punching press mouth 6 is unanimous and identical each other with the shape of punching press mouth 7 down, and last punching press mouth 6 and punching press mouth 7 down are "Z" style of calligraphy.

Wherein, base 5's material is magnet, and bottom plate 4 and base 5 integrated into one piece are equipped with a plurality of fixed orificess 8 in the four corners department of bottom plate 4, and bottom plate 4 conveniently fixes on the workstation through fixed orifices 8.

When the structure is used, place utmost point ear at base 5's lower pressure port 7 department, base 5 adsorbs fixed utmost point ear, the lift driving piece drives drift 2 down, drift 2's upper pressure port 6 and base 5's lower pressure port 7 are for extruding utmost point ear, receive the utmost point ear after the extrusion and bend the back and form the product after bending, utmost point ear 9 after bending and electric core 10 phase-match welding, through changing utmost point ear welding mode, it is connected with electric core to have optimized utmost point ear, the process space is practiced thrift, original personnel manual turnover mode has also been changed, the risk is reduced.

The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the utility model as claimed.
