Description

Technical Field

[0001] The utility model specifically relates to the technical field of battery core outer wall stamping dies, in particular to a battery core outer wall stamping forming die. Background Art

[0002] The outer wall of the battery cell is used to effectively fasten the powder inside the battery. In this way, when the battery is in use, the output of the battery power is achieved through the reaction between the powders inside the battery. The outer wall of the traditional battery cell is cylindrical. Therefore, when stamping, the outer shell needs to be seamlessly set. This can effectively prevent the battery from leaking and effectively ensure the quality and efficiency of the battery.

[0003] However, when the conventional stamping forming device is stamping the outer wall, it is necessary to weld the joint of the outer wall after the stamping is completed. Since the thickness of the outer wall is relatively thin, it is easy to cause the outer wall to penetrate during welding, so that the protection of the inner part by the outer wall of the battery cell cannot be effectively realized. In addition, when the outer wall of the conventional battery is stamped, the outer wall needs to maintain the same size to achieve a unified standard for the battery, so that the battery can be effectively installed during use. Although the conventional battery can achieve uniform size processing of the outer wall through the same mold during stamping, when the inner cavity of the mold is damaged, the outer wall processed by the conventional stamping device will deviate, and the uniform size of the outer wall cannot be effectively guaranteed.

[0004] In view of the above situation, we provide a stamping die for the outer wall of the battery cell. In this device, when stamping the outer wall, the raw material of the outer wall is placed on the positioning plate, and the movable plate and the stamping column are driven by the oil cylinder to move at a uniform speed toward the inner cavity of the rotating drum, so that the raw material is stamped into the inner cavity of the rotating drum. The driving motor fixedly installed at the bottom of the rotating drum drives the rotating drum to rotate effectively, so that the surface of the outer wall is processed into a ring shape to prevent the outer wall from being damaged due to the mold during stamping. After the processing is completed, the size uniformity cannot be effectively guaranteed. The outer wall surface can also be processed through the rotation of the rotating drum, so that the production efficiency is effectively improved when the outer wall of the battery cell is stamped. Utility Model Content

[0005] The purpose of the utility model is to provide a battery cell outer wall stamping forming die, in the device, the outer wall is squeezed into the inner cavity of the drum by a stamping column to achieve the molding of the outer wall, after the stamping column is pressed into place, the stamping column stops moving, and the drum is driven by a driving motor to rotate at a uniform speed, when the drum rotates, through the cooperation with the stamping column, the surface of the outer wall is effectively processed into the same size, so that standardization can be achieved in the later use of the battery, so as to solve the problems of the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A battery cell outer wall stamping forming die comprises a rotating drum, which is fixedly mounted on the output shaft of a driving motor, and one end of the rotating drum away from the driving motor is movably mounted through a slider and a slide groove provided at the bottom of a positioning plate; the positioning plate is fixedly mounted on a fixing plate through a support rod, and during forming, the rotating drum is driven by the driving motor to rotate at a uniform speed, so that the outer wall is formed into the same size during processing.

[0008] The inner part of the rotating drum near one end of the positioning plate is integrally provided with a protrusion; the top of the positioning plate is provided with a movable plate, so that when the rotating drum rotates, the groove on the outer wall of the battery cell is processed by the protrusion provided in the inner cavity of the rotating drum.

[0009] Furthermore, the movable plate is movably mounted on the positioning plate through a first sliding column and a second sliding column; wherein a spring is sleeved on the surface of the first sliding column. When stamping, the spring can effectively prevent the movable plate from suddenly falling and causing damage to the positioning plate and the rotating drum; it can also effectively provide a buffering effect on the positioning plate and the rotating drum during the downward pressing process.

[0010] Furthermore, a stamping column is fixedly installed on one side of the movable plate close to the positioning plate; a groove is opened on one end of the stamping column close to the movable plate; when the drum rotates, the outer wall surface of the battery cell is effectively processed through the cooperation between the protrusion and the groove.

[0011] Furthermore, the first sliding column and the second sliding column are both diagonally arranged, and are respectively located at the four corners of the movable plate, so that when the movable plate is pressed down, the movable plate is positioned and guided to prevent the offset between the stamping column and the rotating drum.

[0012] Furthermore, the top of the movable plate is fixedly mounted on the oil cylinder; and the distance between the movable plate and the positioning plate is greater than the length of the stamping column.

[0013] Furthermore, the driving motor is fixedly mounted on a fixing plate, and the fixing plate is fixedly mounted to a supporting seat by bolts.

[0014] Furthermore, the inner cavity of the rotating drum cooperates with the surface of the stamping column to form the outer wall of the battery core.

[0016] 1. When the battery cell outer wall stamping die is used, the raw material to be stamped is placed on the positioning plate, and the movable plate is driven downward by the oil cylinder. During the downward pressing process of the movable plate, the stamping column fixed on the movable plate is extended to the inside of the rotating drum to realize the stamping of the outer wall of the battery cell;

[0017] 2. After the stamping column moves into position, the battery cell outer wall stamping die drives the drum to rotate at a constant speed through the driving motor fixedly installed on the fixed plate, so that the outer wall of the battery cell is processed into a standard part, so that standardized production and processing can be achieved in the later use of the battery;

[0018] 3.
