Description

Technical Field

[0001] This utility model belongs to the technical field of molds for battery production, and specifically relates to a stamping mold for battery copper busbars. Background Technology

[0002] A battery pack is composed of multiple battery cells or battery modules connected together by copper busbars. As a crucial conductive component in the battery system, the copper busbars function as conductors, connectors, current distributors, and heat dissipators. One method for producing copper busbars is the stamping method using molds. A stamping die is designed and manufactured according to the shape and size of the copper busbar. The stamping die is mounted on the worktable of a stamping machine and includes an upper die base and a lower die base. The lower die base is fixed to the worktable of the stamping machine, and the upper die base is connected to the stamping machine. During the manufacturing process, copper plates or strips are placed on the lower die base of the stamping die. The upper and lower die bases then apply impact force to the copper plate or strip material, causing plastic deformation under the action of the die, thus stamping out the required shape of the copper busbar.

[0003] When the upper and lower die holders of the stamping die are closed to stamp copper strip material, the copper strip material on both sides of the stamping die is usually in a suspended and swaying state. There is no design on the stamping die to support the copper strip material. The suspended copper strip material may sway and deviate at the stamping position. The position of the copper strip during stamping will be deviated, affecting the stamping accuracy and having shortcomings.

[0004] Existing stamping dies lack anti-skewing design to limit the copper material. To address this, this application proposes a stamping die for battery copper busbars. Utility Model Content

[0005] The purpose of this utility model is to provide a stamping die for a battery copper busbar, so as to solve the problem mentioned in the background art of the lack of anti-skewing design for limiting copper material on the stamping die.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 6 This utility model provides a technical solution: a stamping die for battery copper busbars, including a die assembly for stamping battery copper busbars, comprising a lower die base 11 and an upper die base 12, wherein the battery copper busbar is... Figure 1 Workpiece A is stamped by a die set 11 and an upper die set 12. The structure and principle of the stamping die are existing technologies and will not be described in detail in this application. The rolling assembly includes a support plate 2 fixed to the lower die set 11 by screws, a side plate 31 perpendicular to the support plate 2, a fixed shaft 32 installed between opposing side plates 31, and a rolling cylinder 33 sleeved on the outside of the fixed shaft 32. The support plate 2 supports the side plate 31, and the side plate 31 supports and fixes the stabilizing plate 4 and the fixed shaft 32. When workpiece A is fed, it passes through the adjacent rolling cylinder 33. The rolling cylinder 33 presses down on workpiece A and supports workpiece A to prevent workpiece A from shaking significantly. The stabilizing plate 4 is glued to the side plate 31, and a limiting plate 8 is glued to the stabilizing plate 4. The stabilizing plate 4 limits the sliding column 7, and the limiting plate 8 limits the connecting plate 6. The limiting plate 8 is supported by spring steel material. The limiting plate 8 is elastic and can be tilted to facilitate the movement of the connecting plate 6. The opposing surfaces of the limiting plate 8 are provided with slots 81, and the clamping plate 61 is embedded in the slots 81 to achieve the effect of limiting the clamping plate 61. The anti-skewing component includes a sliding column 7 that slides through the stabilizing plate 4, a connecting plate 6 and a stop bar 5 that are fixedly connected to both ends of the sliding column 7, and a pressure plate 9 that is connected to both ends of the stop bar 5. The clamping plate 61 is glued to the center of the connecting plate 6. The stop bar 5 blocks the workpiece A to prevent the workpiece A from skewing, and the pressure plate 9 presses down on the workpiece A to prevent the workpiece A from jumping and thus skewing. The conveyed workpiece A is limited by the stop bar 5 and the pressure plate 9. The pressure plate 9 is made of spring steel and has a buffering property. When the workpiece A has jumping inertia, the pressure plate 9 weakens the jumping inertia of the workpiece A. The clamping plate 61 is limited by the limiting plate 8 to prevent the connecting plate 6 and the clamping plate 61 from loosening.

[0027] In this embodiment, the support plate 2 has a "U" shaped structure, the side plate 31 is installed at the corner of the support plate 2, the end of the fixed shaft 32 passes through the side plate 31, and the side plate 31 supports the fixed shaft 32.

[0028] In this embodiment, the sliding column 7 is perpendicular to the stabilizing plate 4, the stop bar 5, and the connecting plate 6. The stop bar 5 is perpendicular to the stabilizing plate 4, the stabilizing plate 4 and the connecting plate 6 are parallel, and the positions of the stop bar 5 and the connecting plate 6 are accurately installed.

[0029] In this embodiment, the limiting plate 8 has a "U" shaped structure. The outer surface of the stabilizing plate 4 is attached to the inner surface of the limiting plate 8. The clamping plate 61 is vertically connected to the plate 6. The clamping plate 61 cooperates with the slot 81. The limiting plate 8 limits the connecting plate 6. The clamping plate 61 is embedded in the slot 81. The limiting plate 8 has the function of limiting the clamping plate 61.

[0030] In this embodiment, the pressure plate 9 includes a round rod portion and a wave portion. One end of the round rod portion is inserted into the interior of the stop bar 5. The pressure plate 9 serves to press the workpiece A. The distance between the opposing pressure plates 9 is the spacing H. The distance between the opposing rolling cylinders 33 is the same as the spacing H. The size of the spacing H can be designed according to the thickness of the workpiece A. The pressure plate 9 and the rolling cylinder 33 press down on the workpiece A, which can prevent the workpiece A from shaking significantly.

[0031] Working principle and usage process of this utility model:

[0032] When workpiece A is fed into the space between the lower die holder 11 and the upper die holder 12, workpiece A passes between the opposing rolling cylinders 33. The rolling cylinders 33 restrain workpiece A and prevent workpiece A from jumping.

[0033] Workpiece A continues to be conveyed, and the two sides of workpiece A slide in contact with the stop bar 5. The two sides of workpiece A are restricted by the stop bar 5 to prevent workpiece A from deviating.

[0034] Pressure plate 9 holds down workpiece A to prevent it from shaking;

[0035] When adjusting the position of the stop bar 5, the opposing surfaces of the limit plate 8 can be pried outward to increase the distance between the opposing surfaces of the limit plate 8. The connecting plate 6 can be pushed and pulled to change the position of the stop bar 5, which is suitable for workpieces A of different widths.

[0036] In summary: The stamping die has a limit design to prevent the copper strip material from deflecting. The copper strip material passes between the opposing rolling cylinders 33. The two sides of the copper strip material are limited by the stop bar 5. The pressure plate 9 presses down on the copper strip material to prevent the copper strip material from deflecting and jumping during the stamping of the upper die holder 12 and the lower die holder 11, which would cause the copper strip to deviate in shape during stamping.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
