Abstract

The utility model discloses a battery pole lug punching trimming die and belongs to the technical field of battery and machinery. The battery pole lug punching trimming die comprises a lower die, an upper die and a top plate. The upper die is connected with the top plate through a locating guide pillar. A guide pillar groove is arranged in the corresponding position of the lower die. The lower surface of the top plate is provided with a trimming blade and a punching needle, wherein the trimming blade and the lunching needle penetrate the upper die and the lower die. A prepressing spring is arranged between the upper die and the lower die. A chuck is arranged on the upper surface of the top plate. The battery pole lug punching trimming die has the advantages of being simple in structure, convenient to use, capable of guaranteeing vertical aligning of pole pieces, trimness of pole plate groups and little error of the size and the height of the whole and avoiding of appearance of micro short circuit phenomenon of the pole pieces. The battery pole lug punching trimming die solves the problems that the length and the size of each pole lug are needed to be different in the process of assembling the battery pole plate groups, overlap of the pole pieces is untidy caused by unified processing of the pole lugs, and battery capacity is bad due to displacement of the pole plates. The battery pole lug punching trimming die is mainly used for reshaping and punching the pole lug portions and trimming the top portions of the pole lugs of half pole plate groups after the pole pieces are combined.

Description

Die for punching and cutting battery tabs

technical field

The utility model relates to a battery machining tool, in particular to a battery component processing mold, which belongs to the technical field of batteries and machinery. the

Background technique

At present, the production of pole pieces of square batteries is usually punched into shape first, then the tabs and pole pieces are rolled and welded into one, and then laminated, and the pole piece group and the pole are connected with bolts or rivets. Together. After the tabs are punched first, when the laminations are combined and fixed with bolts, the pole pieces will be misaligned due to the different deformation degrees of the tab parts, which will make the pole plate group uneven and cause a large error in the overall height and size. In this method, due to the different thicknesses of the lugs and the pole pieces, the degree of deformation of the lugs is not the same when they are combined and connected, so that the plates are staggered and inconsistent with each other. Firstly, the appearance is irregular and the height error increases; secondly, it also increases The chance of micro-short circuit between pole pieces is eliminated. the

Utility model content

In view of the above problems, the utility model provides a lug processing mold. the

The technical solution adopted by the utility model to solve the technical problem is: the battery lug punching and cutting mold, including the lower template, the upper template and the top plate; the upper template and the top plate are connected by positioning guide posts; the corresponding positions of the lower template are provided with guide posts slot; the lower surface of the top plate is provided with a cutting blade and a punching needle that run through the upper template and the lower template; a pre-compressed spring is provided between the upper template and the lower template; the upper surface of the top plate is provided with a chuck. the

The utility model has the beneficial effects of simple structure and convenient use; it can ensure the vertical alignment between the pole pieces, the pole plate groups are even, the overall height and dimension error is small, and the micro-short circuit between the pole pieces is avoided. Solve the problem of inconsistency in the length and size of each tab required in the assembly process of the battery plate group; also solve the problem of uneven stacking of the tabs caused by the unified processing size of the tabs in the past, and the poor performance of the battery capacity due to plate misalignment question. It is mainly used for shaping, punching and trimming the top of the tabs of the tabs of the half-plate group after the pole piece assembly. the

Detailed ways

Below in conjunction with embodiment the utility model is further described. the

Referring to Fig. 1, the mold for punching and cutting the battery lugs includes a lower template 1, an upper template 2 and a top plate 3; the upper template 2 and the top plate 3 are connected by positioning guide posts 4; the corresponding position of the lower template 1 is provided with guide post grooves 5; The lower surface of the top plate 3 is provided with a cutting blade 6 and a punching needle 7 that run through the upper template 2 and the lower template 1; a preload spring 8 is provided between the upper template 2 and the lower template 1; the upper surface of the top plate 3 is provided with a clip head 9. the

The lower template 1 is provided with a limit pin 10 . the

Adjust the punching process of the connecting bolt holes of the tabs from the pole piece punching process to the lamination process, and then carry out the shaping and punching of the tabs of the pole piece group, and cut the tops of the tabs that are not flush with each other after shaping cut. Reshaping design is adopted on the punching die. First, the head of the tab of the plate group is pre-finished to the actual use state, and then it is punched, and the uneven part of the top of the tab caused by the plastic is trimmed. . Under the premise that the height of the pole plate group remains unchanged, the upper and lower alignment between the pole pieces is guaranteed. the

After clamping the semi-polar plate group by the fixing device, manually extend the tab part of the polar plate group into the mold and position it through the baffle plate. The punch press passes through the chuck 9 to drive the upper mold frame down. 1 Pressing, through the forming surface of the lower template 1, the deformation and shaping of the ear parts are carried out. In order to ensure the force balance of the mold base, the downward position of the upper template 2 is limited by the limit pin 10. After the lug shaping is completed, the upper template 2 stops descending after touching the limit pin 10, the upper mold frame continues to press down, the preload spring 8 is compressed, and at this time, the punching needle 7 and the trimming blade 6 are released from the upper template. 2 through the guide hole, punching the tab part, and because the length of the cutting blade 6 is slightly shorter than that of the punching needle 7, after the punching limit of the tab part, the cutting blade 6 is also aligned with the pole. The tops of the ears are trimmed. the

Through the shaping, punching, and trimming of the tab part of the half plate group, it is avoided that the tab part is punched first, and when the laminations are assembled and fixed with bolts, the pole tab part will not be deformed due to the different degrees of deformation. The plates are staggered between each other, which makes the plate group uneven, and also causes a large error in the overall height and size. the
