[0029] In this embodiment, a solenoid valve 44 for controlling the downward pressure cylinder 41 is also fixedly connected to the side surface of the back plate 11 .

[0030] Working process and principle:

[0031] When the tool is used, the lithium battery top cover 6 is first placed in the contoured groove 221, and the pin 65 passes through the notch 222. Then the pressing cylinder 41 is started, the output shaft of the pressing cylinder 41 is extended, and the pressing plate 42 is driven to move downward, and the pressing block 431 moves downward with the spring.

[0032] The pressing block 431 first contacts the lithium battery top cover 6, and the pressing plate 42 continues to press down, the spring 434 is compressed, the pressure applied by the pressing block 431 on the lithium battery top cover 6 increases, the structure at the bottom of the pressing block 431 matches the structure of the lithium battery top cover 6, and the bare aluminum sheet 61 is flattened.

[0033] As the pressure plate 42 continues to press down, the support plate 5 moves downward, and the roller 38 contacts the inclined surface of the trapezoidal structure of the support plate 5, causing the slide plate on which it is located to move toward the pin 65. The spring 2 37 is compressed, and the top block 31 acts on the pin 65, causing the pin 65 to expand outward to a state perpendicular to the plain aluminum sheet 61.

[0034] At the same time, the downward side blocks 436 press the two ends of the light aluminum sheet 61 to prevent the two ends of the light aluminum sheet 61 from tilting up when the pins 65 are calibrated, thereby ensuring the quality of the lithium battery top cover 6.

[0035] After the shaping is completed, the output shaft of the downward pressure cylinder 41 is reset, the pressing plate 42, the pressing block 431 and the opening plate 5 move upward, and the slide plate moves to the middle and resets under the action of the spring 2 37.

[0036] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the above disclosed embodiments are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
