Description

Technical Field

[0001] This utility model belongs to the field of battery manufacturing technology, and specifically relates to a battery casing stamping device. Background Technology

[0002] Battery casing stamping equipment is a specialized stamping device used to produce battery casings (such as cylindrical, square, or pouch battery casings). Its core is to plastically deform metal sheets through molds and presses to form a high-precision, highly consistent casing structure.

[0003] Existing battery casing stamping equipment places the metal sheet to be stamped in a designated position, and then a hydraulic press drives a punch to press down on the metal sheet. The punch and die together draw the sheet into a casing, thus completing the battery casing stamping process. However, in actual use, during the stamping of the metal sheet, personnel need to manually adjust the position of the metal sheet to ensure it is centered before the hydraulic press drives the punch to press down and form the battery casing. However, the battery casing forming process requires continuous stamping of the metal sheet, which necessitates continuous adjustment of the metal sheet's position, making it cumbersome, time-consuming, and labor-intensive. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a battery casing stamping device that can automatically correct the position of the metal sheet during stamping to ensure that the material is centered, thereby enabling stable and automatic stamping of the metal sheet and facilitating its use.

A plurality of clearance openings are provided on the upper surface of the stamping base, and the correction rods are installed in cooperation with the clearance openings. A drive module is also provided on the rotating seat, and the drive module is used to drive the correction rods to rotate. A plurality of motors are provided on the lower surface of the stamping base, and the output shafts of the motors are fixed to the adjacent rotating shafts by couplings. A worktable is provided on the lower surface of the stamping base, a plurality of support legs are provided on the lower surface of the worktable, and a staggered sliding door is slidably provided on the front side of the worktable.

[0006] As a further improvement of this utility model, the drive module includes a worm gear fixedly sleeved in the middle of the outer arc surface of the rotating rod, a bearing seat is provided at the bottom of the inner side of the rotating seat, and a worm is rotatably provided between the bearing seat and the inner wall of the adjacent rotating seat, and the adjacent worms are fixed together by a coupling; a motor is provided on the outer side of the rotating seat, and the output shaft of the motor is fixed to the adjacent worm by a coupling.

The telescopic ends of the hydraulic push rods are all provided with punches, and the punches are respectively installed in conjunction with the vertically adjacent dies.

[0008] As a further improvement of this utility model, a control board is provided on the front side of the stamping seat, and the hydraulic push rod, motor one and motor two are all electrically connected to the control board.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] First, the metal sheet to be stamped is placed on the die. The motor is controlled by the control board to run, so that the rotating rod drives the correction rods at both ends to rotate towards the side closer to the vertical center of the rotating seat. In turn, the rotating rod drives the correction rod to extend out of the stamping seat through the clearance, pushing the metal sheet to correct its position.

[0011] Secondly, after controlling motor one to run in reverse, the control board regulates the operation of motor two, so that motor two drives the rotating seat to rotate 90 degrees through the rotating shaft, and then motor one is restarted to correct the position of the metal sheet from another direction.

[0012] Thirdly, the cooperation of motor one and motor two can automatically correct the position of the metal sheet during stamping to ensure that the material is centered, thereby enabling stable and automatic stamping of the metal sheet.

[0013] Fourth, the internal space of the workbench can be opened by pulling the sliding door, and then the internal space of the workbench can be used to store the instruments that need to be used. Attached Figure Description

Detailed Implementation

[0020] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0021] like Figure 2 , 4 As shown, the device includes a stamping base 104, on which multiple dies 105 are provided. Multiple rotating shafts 201 are rotatably provided at the bottom of the stamping base 104. Each rotating shaft 201 has a rotating seat 202 at its top. Symmetrically distributed rotating rods 203 are rotatably provided inside each rotating seat 202. Correcting rods 204 are fixedly sleeved at both ends of each rotating rod 203. Multiple clearance openings 205 are provided on the upper surface of the stamping base 104. The correcting rods 204 are installed in conjunction with the clearance openings 205. A drive module is also provided on the rotating seat 202 to drive the correcting rods 204 to rotate.

[0022] like Figure 2 , 3 As shown, the drive module includes a worm gear 206 fixedly sleeved in the middle of the outer arc surface of the rotating rod 203; a bearing seat 207 is provided at the bottom of the inner side of the rotating seat 202; a worm 208 is rotatably provided between the bearing seat 207 and the inner wall of the adjacent rotating seat 202; and the adjacent worms 208 are fixed together by couplings; a motor 209 is provided on the outer side of the rotating seat 202; and the output shaft of the motor 209 is fixed to the adjacent worm 208 by couplings; and multiple motors 210 are provided on the lower surface of the stamping seat 104; and the output shaft of the motor 210 is fixed to the adjacent rotating shaft 201 by couplings.

[0023] like Figure 1 , 4As shown, a mounting bracket 106 is provided on the upper surface of the stamping base 104. Multiple hydraulic push rods 107 are provided at the upper end of the mounting bracket 106. Each extension end of the hydraulic push rod 107 is provided with a punch 108.

[0024] like Figure 1 As shown, a control board 301 is provided on the front side of the stamping base 104, and the hydraulic push rod 107, motor 1 209 and motor 210 are all electrically connected to the control board 301.

[0025] In use, the metal sheet to be stamped is placed on the die 105. Then, the control board 301 controls the motor 209 to run, causing the motor 209 to drive the worm gear 208 connected to it to rotate. The coupling between the worm gears 208 makes the two worm gears 208 rotate synchronously. The meshing relationship between the worm gear 208 and the worm wheel 206 drives the worm wheel 206 to rotate, which in turn drives the rotating rod 203, which is located on the worm wheel 206, to rotate. This causes the rotating rod 203 to drive the correction rods 204 at both ends to rotate towards the vertical center of the rotating seat 202. This causes the rotating rod 203 to drive the correction rods 204 to pass through the avoidance The nozzle 205 extends out of the stamping seat 104, and then pushes the metal sheet to correct its position. Then, the motor 209 is controlled to run in reverse, causing the correction rod 204 to rotate away from the vertical center of the rotating seat 202, so that the correction rod 204 retracts into the rotating seat 202. Then, the control board 301 controls the motor 210 to run, so that the motor 210 drives the rotating seat 202 to rotate 90 degrees through the rotating shaft 201. Then, the motor 209 is restarted, so that the motor 209 drives the correction rod 204 to rotate closer to the vertical center of the rotating seat 202, correcting the position of the metal sheet from another direction.

[0026] Then, the control board 301 controls the operation of the hydraulic push rod 107, so that the extension end of the hydraulic push rod 107 drives the punch 108 to press down, and the battery case is stamped and formed by the cooperation of the punch 108 and the die 105.

[0027] According to another embodiment of the present invention, such as Figure 1 , 2 As shown, a workbench 101 is provided on the lower surface of the stamping base 104, and multiple support legs 102 are provided on the lower surface of the workbench 101.
