Description

Technical Field

[0001] This utility model relates to the field of battery steel shell production technology, and in particular to a one-outlet, ten-feeding equipment for large cylindrical battery steel shells. Background Technology

[0002] A battery is a cup, tank, or other container or composite container containing an electrolyte solution and metal electrodes to generate an electric current. It is a device that converts chemical energy into electrical energy. With the development and innovation of new energy technologies, the application scope of batteries has become more extensive. The battery steel shell is the protective shell of the battery. It is made by stretching steel plates through a machine. Before being stretched into a finished product, the steel plates are cut into round pieces by stamping equipment, and then the round pieces are initially stamped into round covers. For example, existing published documents CN117086180A - A stamping device for battery steel shells and CN218693248U - A stamping fixture for battery steel shell sheet metal both disclose a stamping device for producing battery steel shells. Although the stamping device can produce steel shells, the production efficiency is low and cannot meet the current production efficiency requirements. Therefore, it is necessary to improve the existing technology to solve the above-mentioned technical problems. Utility Model Content

[0013] The beneficial effects of this utility model are as follows: When the equipment is in use, the motor can drive the eccentric drive shaft to move up and down, thereby realizing the reciprocating motion of the outer protective box in the up and down direction. The steel plate to be stamped and cut passes through the two inlets and outlets, and passes between the lower pressure plate and the lifting plate. When the outer protective box moves down, it drives the lower pressure plate to move down. The ring cutter will first cut a disc from the steel plate. As the lower pressure plate continues to move down, the forming head will move further down relative to the movable ring, thus squeezing the disc into the forming cylinder. With the help of the forming head, the disc becomes a cylindrical box to be further processed. After stamping, the cylindrical box is discharged from the outlet. With the setting of ten forming components, ten cylindrical boxes can be stamped at one time, which effectively improves production efficiency and has good overall practicality.

[0025] Please refer to Figure 1 , Figure 2 and Figure 3As shown, this is the first embodiment of the present invention. This embodiment provides a large cylindrical battery steel shell one-out-ten-feeding device, including a drive mechanism 100, including an outer protective box 101 and an eccentric drive shaft 102 arranged vertically in the outer protective box 101; and a stamping mechanism 200 arranged in the outer protective box 101 below the eccentric drive shaft 102, including an outer protective box 201, a forming component 202, a lifting plate 203 and a lower template 204 arranged sequentially from top to bottom; A motor 102a is fixed on the top surface of the outer protective box 101, and a drive wheel 102a-1 is fixed on the output shaft of the motor 102a. The input end of the eccentric drive shaft 102 is engaged with the output shaft of the output wheel 102c, and the output wheel 102c and the drive wheel 102a-1 are driven by a belt 102b. Inlet and outlet 101a are opened on the outer protective box 101 on both the left and right sides of the stamping mechanism 200. In use, the above-mentioned setup enables the drive wheel 102a-1 to rotate via the belt 102b, which in turn drives the output wheel 102c to rotate. The output shaft of the output wheel 102c drives the eccentric drive shaft 102, thereby enabling the stamping mechanism 200 to reciprocate in the vertical direction. The steel plate enters and exits through the two inlets and outlets 101a. With the help of the stamping mechanism 200, the cutting and stamping of discs from the steel plate can be achieved. Example 2

[0026] Please refer to Figure 3 , Figure 4 and Figure 5 As shown, this is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that, in order to better implement the present invention, the structure for cutting the steel plate used in the present invention is described in detail.

[0027] The lifting plate 203 has ten through holes 203b arranged in an array, and ten forming components 202 are arranged one-to-one above the ten through holes 203b. The forming component 202 includes a connecting rod 202a, a fixed ring 202b and a movable ring 202c. A ring cutter 202c-1 is coaxially fixed on the bottom surface of the movable ring 202c. A connecting plate 201a is fixed on the top surface of the outer protective box 201, and the connecting plate 201a is fixedly connected to the output end of the eccentric drive shaft 102. Limiting posts 204a are fixedly connected at the four corner positions of the top surface of the lower template 204. A limiting sleeve 201b for sliding engagement of the limiting post 204a is fixed on the lower pressure plate 201c, so as to limit and guide the movement of the lower pressure plate 201c. In use, the eccentric drive shaft 102 moves downward, which in turn drives the lower pressure plate 201c to move downward through the connecting plate 201a. This allows the ten forming components 202 to move downward synchronously. With the limiting of the lifting plate 203 and the shaping of the through hole 203b, the ring cutter 202c-1 in the ten forming components 202 simultaneously punches and cuts the steel plate, thereby cutting out circular pieces from the steel plate.

[0028] Furthermore, the ten through holes 203b are divided into two groups, with five through holes 203b in each group arranged in an array along the left-right direction, and the two groups of through holes 203b are staggered. Example 3

[0029] Please refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 The following is a second embodiment of the present invention. This embodiment is based on the previous embodiment. The difference is that, in order to better implement the present invention, the structure of the steel plate used in the present invention being further stamped into a cylindrical box after being cut into circular pieces is described in detail.

[0030] The movable ring 202c has a forming head 202a-2 inside, and the forming head 202a-2 is fixed to the top surface of the outer protective box 201 through the connecting rod 202a. The inner wall of the movable ring 202c has telescopic columns 202c-2 arranged in a circumferential array. The bottom surface of the fixed ring 202b has a telescopic sleeve 202b-1 for slidingly engaging the upper end of the telescopic column 202c-2. A spring is slidably engaged on the telescopic column 202c-2 inside the telescopic sleeve 202b-1. The fixed ring 202b is fixedly engaged on the connecting rod 202a, so that the movable ring 202c can be automatically reset. The lower inner side of the outer protective box 201 is fixedly connected to a lower pressure plate 201c, and the bottom surface of the lower pressure plate 201c has a placement groove 201c-1 for placing the movable ring 202c, so as to facilitate the up and down movement of the movable ring 202c. A connecting column 202a-1 is fixedly provided on the bottom surface of the connecting rod 202a, and a forming head 202a-2 is fixedly sleeved on the outside of the connecting column 202a-1, which facilitates the automatic disassembly and replacement of the forming head 202a-2. A discharge cylinder 204b is fixedly provided on the top surface of the lower template 204 directly below the through hole 203b. The lower template 204 is fixedly connected to the top surface of the fixing plate 205, and the fixing plate 205 is fixedly connected to the outer protective box 101. A forming cylinder 203a is fixedly provided on the bottom surface of the lifting plate 203 at the position of the through hole 203b. A discharge port 205a is opened on the fixing plate 205 directly below the discharge cylinder 204b. Telescopic rods 203c are fixed at the four corners of the bottom surface of the lifting plate 203, and the lower end of the telescopic rods 203c is fixedly connected to the top surface of the lower template 204. This enables the lifting plate 203 to automatically move upward and reset, which facilitates the unloading of materials after subsequent molding. In use, after the ring cutter 202c-1 cuts a circular piece from the steel plate, as the outer protective box 201 continues to move downward, the movable ring 202c remains in the same position, while the connecting rod 202a drives the forming head 202a-2 to continue moving downward, pressing the circular piece into the forming cylinder 203a. With the help of the forming head 202a-2, the circular piece is finally stamped into a cylindrical box. After the stamping is completed, the outer protective box 201 moves upward, and the lifting plate 203 also moves upward synchronously. The formed cylindrical box is discharged through the discharge cylinder 204b and from the discharge port 205a.
