[0031] Working principle: start the device, and place the nickel-hydrogen battery casing raw material in the stamping port 609 of the threaded post 608. At this time, the lifting plate 3 is at the lowest position and supported by the telescopic rod of the air cylinder 9. Start the hydraulic rod 5, the telescopic end of the hydraulic rod 5 pushes the stamping part 7 to move downward, and the stamping part 7 is tightly fitted with the telescopic end of the hydraulic rod 5 through threaded connection to ensure transmission of stamping force. The stamping part 7 moves downward into the stamping port 609, and stamps the raw material into the shape of a nickel-hydrogen battery casing. After stamping is completed, start the air cylinder 9, the telescopic rod of the air cylinder 9 pushes the lifting plate 3 to rise, and the lifting plate 3 rises stably under the guiding action of the guide rods 2. Meanwhile, the motor 601 is started and drives the crank 602 to rotate, and the crank 602 pushes the lifting base 604 to rise through the connecting rod 603. The balls 606 in the lifting base 604 roll in the sliding grooves 607, which reduces friction and ensures stable movement of the lifting base 604. When the lifting base 604 rises, the stamping part 7 at the top of the threaded post 608 ejects the molded nickel-hydrogen battery casing, which facilitates material taking.

[0032] When it is necessary to change the stamping die, first activate the hydraulic rod 5 to raise the stamping part 7. Then, use a wrench to turn the mounting bolts to remove the stamping part 7 from the telescopic end of the hydraulic rod 5. Next, insert the rotating frame 605 into the insertion hole 6010 of the threaded post 608, and rotate the rotating frame 605 to rotate the threaded post 608, causing the threaded post 608 to rise within the lifting seat 604. After the threaded post 608 rises to the top of the lifting seat 604, remove the threaded post 608 and take out the stamping part 7 from the threaded groove on the lifting seat 604. Then, select the corresponding threaded post 608, place it in the threaded groove of the lifting seat 604, and screw it into the lifting seat 604 using the rotating frame 605. Finally, place the corresponding stamping part 7 into the stamping opening 609 of the threaded post 608, and push the stamping part 7 with the telescopic end of the hydraulic rod 5 to align it with the stamping opening 609 of the threaded post 608, completing the die change. During equipment operation, lubricating oil is injected into the oil injection pipe 801 through the oil injection port 802. The lubricating oil is evenly distributed into the slide groove 607 through the branch pipe 804 within the oil injection pipe 801, providing lubrication for the ball bearings 606, reducing friction between the ball bearings 606 and the slide groove 607, and extending the service life of the equipment. The silicone plug 803 is used to seal the oil injection port 802 to prevent lubricating oil leakage.
