Description

Technical Field

[0001] This utility model belongs to the field of stamping die technology, specifically relating to a stamping die for copper busbars of new energy batteries. Background Technology

[0002] New energy battery copper busbars are one of the important components in battery systems, serving functions such as conductivity, connection and fixation, and heat dissipation. New energy battery copper busbars can connect individual batteries or battery packs together to form a complete battery pack. One method of manufacturing new energy battery copper busbars is to use a stamping machine and a stamping die. The stamping die generally 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 punch of the stamping machine. The copper strip material used to manufacture new energy battery copper busbars is fed through the upper die base. The stamping machine drives the upper die base to move down and close with the lower die base, thus achieving the purpose of stamping to manufacture new energy battery copper busbars.

[0003] When the copper strip material for manufacturing battery copper busbars passes between the upper and lower die bases, it is generally suspended and swaying on both sides of the upper and lower die bases. During the conveying of the copper strip material through the upper and lower die bases, due to the swaying of the copper strip material, the closing of the upper and lower die bases will apply a stamping force to the copper material. The copper strip material is unstable and may be skewed, which affects the stamping manufacturing of the copper material. The lower die base of the stamping die does not have an anti-skew design to limit the copper strip material, which is a shortcoming.

[0004] When stamping copper strip material with existing stamping dies, there is a problem that the lower die base of the stamping die does not have an anti-skewing design to limit the copper strip material. To address this, this application proposes a stamping die for copper busbars in new energy batteries. Utility Model Content

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.

[0025] Please see Figures 1 to 4 This utility model provides a technical solution: a stamping die for copper busbars in new energy batteries, including a stamping die assembly for stamping copper busbar strips, comprising a lower die base 11 and an upper die base 12. The structure and principle of the stamping die are existing technologies and will not be described in detail in this application; a support frame, including a support plate 2 fixed to the lower die base 11 by screws, a stabilizing plate 41 fixed to the support plate 2 by screws, and a pressure cylinder 42 installed between opposing stabilizing plates 41. The support plate 2 serves to support the stabilizing plate 41 and the pressure cylinder 42. The copper busbar strip is... Figure 1 The copper strip A is contained within the pressure cylinder 42, which limits its movement and prevents it from swaying excessively. The buffer assembly includes a support plate 51 fixed at one end to a stabilizing plate 41 by screws, a spring plate 52 welded to one end of the support plate 51 at its bottom, and a connecting plate 53 welded to the top of the spring plate 52. A semi-cylinder 54 is welded to the surface of the connecting plate 53. The support plate 51 supports the spring plate 52 and the connecting plate 53, and the semi-cylinder 54 on the connecting plate 53 abuts against the copper strip A, preventing it from sagging and swaying excessively during transport. The spring plate 52 is made of spring steel and has a wavy shape. When the copper strip A experiences a tendency to sway, the spring plate 52 and the connecting plate 53 counteract this tendency. To reduce the tendency of copper strip A to sway and prevent copper strip A from swaying; the anti-skew assembly includes a welded circular block 62 and a positioning rod 63, an anti-skew cylinder 61 sleeved on the outside of the positioning rod 63, and a fixing post 64 welded to the center of the circular block 62. A magnetic ring 621 is glued to the circular block 62. The circular block 62 is placed on the support plate 51, and the fixing post 64 passes through the support plate 51. The magnetic ring 621 is magnetically attracted to the support plate 51, so that the circular block 62 is placed stably on the support plate 51. The anti-skew cylinder 61 is sleeved on the outside of the positioning rod 63. The anti-skew cylinder 61 is distributed on both sides of the copper strip A. The anti-skew cylinder 61 restricts the copper strip A and prevents the copper strip A from skewing.

[0026] In this embodiment, the support plate 2 has an "L" shaped structure, the stabilizing plate 41 has a "U" shaped structure, the stabilizing plate 41 is perpendicular to the support plate 2, and the pressure cylinder 42 is fixed to the stabilizing plate 41 by screws. The pressure cylinder 42 limits the copper strip A to prevent the copper strip A from shaking significantly.

[0027] In this embodiment, the support plate 51 includes a flat plate portion b and symmetrically distributed inclined portions a. The inclined bottom end of the inclined portion a is connected to the stabilizing plate 41, and the bottom end of the spring plate 52 is connected to the flat plate portion b. The spring plate 52 has a wavy zigzag shape, and the connecting plate 53 is parallel to the corresponding flat plate portion b. When the copper strip A has a tendency to sway, the spring plate 52 and the connecting plate 53 counteract and weaken the tendency of the copper strip A to sway, thereby preventing the copper strip A from swaying.

[0028] In this embodiment, a positioning hole 511 is provided on the surface of the flat plate portion b of the support plate 51 for the fixing post 64 to pass through. The fixing post 64 passes through the positioning hole 511, and the circular block 62 is installed accurately.

[0029] In this embodiment, a concave annular mounting groove is formed on the bottom surface of the circular block 62 away from the positioning rod 63. The magnet ring 621 cooperates with the mounting groove. The surfaces of the circular block 62 and the magnet ring 621 on the same side are flush. The magnet ring 621 is magnetically attracted to the flat plate b. The magnet ring 621 is magnetically attracted to the support plate 51, so that the circular block 62 is placed stably on the support plate 51.

[0030] In this embodiment, a vertical plate 31 is provided on the surface of one end of the support plate 2, and a support cylinder 32 is fixed between the opposing vertical plates 31 by screws. The support cylinder 32 supports the copper strip A and prevents the copper strip A from falling.

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

[0032] The lower die holder 11 and the upper die holder 12 press the copper strip A. The copper strip A is conveyed and passes through the position between the support cylinder 31 and the pressure cylinder 42. The support cylinder 31 and the pressure cylinder 42 limit the copper strip A to prevent the copper strip A from shaking significantly.

[0033] The copper strip A passes through the position between the symmetrically distributed anti-skew cylinders 61. The anti-skew cylinders 61 restrict the copper strip A and prevent the copper strip A from skewing.

[0034] The copper strip A slides into contact with the semi-cylinder 54 on the connecting plate 53, and the semi-cylinder 54 abuts against the copper strip A to prevent the copper strip A from falling.

[0035] When copper strip A is being conveyed and a tendency to sway occurs, the spring plate 52 and the connecting plate 53 counteract and weaken the tendency to sway, thus preventing copper strip A from swaying.

[0036] In summary: The lower die base of the stamping die has an anti-skewing design to limit the copper strip material. The support cylinder 31 and the pressure cylinder 42 limit the copper strip A, and the semi-cylinder 54 abuts against the copper strip A to prevent the copper strip A from falling and shaking significantly. The anti-skewing cylinder 61 limits the copper strip A, and the spring plate 52 and the connecting plate 53 counteract and weaken the tendency force of the copper strip A to shake, thus preventing the copper strip A from shaking and deviating.

[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.
