[0034] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0035] The following is in conjunction with the appendix Figures 1-6 This embodiment will be described in further detail.

[0036] like Figure 1 As shown, a battery aluminum shell punching mechanism in this embodiment includes a top plate 100 and a bottom plate 110, which are connected by a first guide post 101. It also includes a lower die assembly on the bottom plate 110 and an upper die assembly on the top plate 100. Specifically, combined with... Figure 2 As shown, the lower mold assembly includes a lower mold base 130, which is bolted to the upper side of the base plate 110. The upper side of the lower mold base 130 has a groove 201 adapted to the aluminum shell of the battery. The upper mold assembly can be raised and lowered along the first guide post 101. The upper mold assembly includes an upper mold base 120 and a punching head 121 disposed on the upper mold base 120. Specifically, the first guide post 101 is slidably disposed through the upper mold base 120 to guide the upper mold base 120. The top plate 100 is also provided with a second cylinder 102 for driving the upper mold base 120 to rise and fall.

[0037] It should be noted that after the aluminum battery casing is stretched by the stretching equipment, it needs to be transferred to the aluminum battery casing punching area to cut off the folded edge at the opening of the stretched aluminum battery casing. In actual use, the opening of the groove 201 forms an overlap groove. After the aluminum battery casing is transferred to the aluminum battery casing punching area, the operator places the aluminum battery casing into the groove 201. At this time, the folded edge of the aluminum battery casing overlaps in the overlap groove. After placement, the second cylinder 102 drives the upper die base 120 to move vertically downward along the first guide post 101, thereby driving the punching head 121 to move downward and punch the folded edge of the aluminum battery casing overlapping in the overlap groove, thus completing the punching of the folded edge at the opening of the aluminum battery casing.

[0038] In this embodiment, a cleaning component is provided in the lower die base 130. The cleaning component is used to push out the debris in the groove 201. That is, in actual use, when the debris generated by punching falls into the groove 201, it affects the placement of the battery aluminum shell in the groove 201. The cleaning component is used to push out the debris in the groove 201, so that the groove 201 is cleaned so that the battery aluminum shell can be placed in the groove 201, which facilitates the continuous operation of the battery aluminum shell punching mechanism.

[0039] In this embodiment, a lifting assembly is provided on the base plate 110. The lifting assembly is used to push out the aluminum battery shell in the groove 201, so that after the aluminum battery shell is punched, the second cylinder 102 drives the upper mold assembly to move up and reset. At this time, the lifting assembly can push the aluminum battery shell after punching out of the groove 201, thereby facilitating the placement and removal of the aluminum battery shell in the groove 201.

[0040] The lifting assembly includes a liftable lifting plate 140, on which a corresponding top rod 141 is inserted and installed, with its upper end extending into the groove 201. The top rod 141 is detachably installed on the lifting plate 140 via an installation assembly.

[0041] In actual use, the base plate 110 is provided with a fixed plate 150 located below the lifting plate 140 via a mounting rod 151. A second guide post 152 is provided between the base plate 110 and the fixed plate 150, which slides through the lifting plate 140 to restrict the lifting of the lifting plate 140. The fixed plate 150 is provided with a first cylinder 160 for driving the lifting plate 140 to rise and fall. Thus, the first cylinder 160 can drive the lifting plate 140 to rise and fall between the base plate 110 and the fixed plate 150, thereby driving the top rod 141 to rise and fall, so that its upper end can rise and fall within the groove 201 to achieve the lifting of the battery aluminum shell.

[0042] It should be noted that the lower mold base 130 in this embodiment can be replaced according to the size of the battery aluminum shell. In order to enable the lifting assembly to adapt to different lower mold bases 130, that is, the upper end of the push rod 141 can extend into the groove 201 of different lower mold bases 130 to lift the battery aluminum shell, in this embodiment, the installation assembly is set to better realize the installation and removal of the push rod 141 on the lifting plate 140, thereby facilitating the adjustment of the position of the push rod 141 so that it can extend into the groove 201 of different lower mold bases 130.

[0043] Combination Figures 3-5 As shown, in this embodiment, the upper side of the lifting plate 140 is provided with a plurality of insertion slots 301 arranged in parallel along its length direction, and the sidewalls opposite to the insertion slots 301 are provided with positioning holes 401.

[0044] The mounting assembly includes a plug block 410 fixedly disposed at the lower end of the top rod 141. The plug block 410 can extend into the corresponding plug groove 301. Specifically, the size of the plug groove 301 is adapted to the size of the plug block 410, that is, when the plug block 410 is inserted into the plug groove 301, the gap between the plug block 410 and the plug groove 301 is small, so that the plug block 410 is not easy to shake in the plug groove 301. The plug block 410 is provided with a plug cavity 501, and a telescopic plug rod 411 is provided in the plug cavity 501. The plug rod 411 extends into the corresponding positioning hole 401 to fix the plug block 410 in the plug groove 301.

[0045] Specifically, in order to achieve the extension and retraction of the plug rod 411, in this embodiment, a sliding block 520 is provided in the plug cavity 501, and the sliding block 520 is slidably disposed in the plug cavity 501. One end of the plug rod 411 extends out of the plug block 410, and the other end is fixedly connected to the corresponding sliding block 520. A first spring 530 is sleeved on the plug rod 411 located in the plug cavity 501. One end of the first spring 530 abuts against the sliding block 520, and the other end abuts against the end wall of the plug cavity 501, so that the first spring 530 is used to drive the sliding blocks 520 to move closer to each other, so as to realize the retraction of one end of the plug rod 411. The top rod 141 is provided with a mounting cavity communicating with the plug cavity 501. The mounting cavity is provided with a driving member for driving the sliding blocks 520 to move away from each other so as to realize the extension of the plug rod 411.

[0046] In this embodiment, the upper end of the mounting cavity is open, and a plugging ring 540 is threaded at the opening of the mounting cavity;

[0047] The driving component includes a driving rod 550 whose lower end extends into the insertion cavity 501. The insertion block 410 has guide surfaces 521 at its opposite ends and upper ends. Specifically, the two guide surfaces 521 are arranged in a V-shape. The lower end of the driving rod 550 is located between the two guide surfaces 521, and an arc surface 551 that mates with the guide surfaces 521 is formed along its circumference. A pull rod 552, whose upper end extends through a blocking ring 540, is fixedly installed at the upper end of the driving rod 550. A second spring 560 is sleeved on the pull rod 552 located in the mounting cavity. Specifically, the upper end of the second spring 560 abuts against the blocking ring 540, and the lower end abuts against the upper end of the driving rod 550, so that the second spring 560... The drive rod 550 is pushed down. The elastic force of the second spring 560 is much greater than the sum of the elastic forces of the two first springs 530. Therefore, in the natural state, the second spring 560 is used to push the drive rod 550 down. During this process, the arc surface 551 presses the guide surface 521 so that the two sliding blocks 520 overcome the elastic force of the first springs 530 and move away from each other. This causes the first springs 530 to be compressed and the plug rod 411 to extend out of the plug block 410 until the lower end of the drive rod 550 abuts against the bottom wall of the plug cavity 501. This ensures that the plug rod 411 is always in the extended state, which is convenient for installing the top rod 141.

[0048] When the operator drives the lifting plate 140 to its lowest position via the first cylinder 160, the upper end of the top rod 141 is completely below the top plate 100. At this time, the operator lifts the pull rod 552 to move the drive rod 550 upward and retract it into the mounting cavity. During this process, the first spring 530 resets, thereby driving the two sliding blocks 520 to move closer to each other, so that the insertion rod 411 retracts, thus facilitating the placement and removal of the insertion block 410 in the insertion slot 301. Therefore, when changing the position of the top rod 141, it is only necessary to lift the pull rod 552, which is simple and convenient to operate and beneficial to practical use.

[0049] Specifically, in order to enable the drive rod 550 and the sliding block 520 to slide smoothly by pulling the lever 552, in this embodiment, rubber pads are provided at both ends of the first spring 530 and the second spring 560. The rubber pads are used to buffer and absorb energy, so that the sliding of the drive rod 550 and the sliding block 520 is more stable. In order to realize the installation of the sliding block 520 and the first spring 530 in the insertion cavity 501, in this embodiment, the lower opening of the insertion cavity 501 is provided, and a plug is installed at the opening by screws.

[0050] Combination Figure 6 As shown, in this embodiment, a cleaning groove 202 communicating with the groove 201 is provided on the front side of the lower mold base 130. Specifically, the bottom wall of the cleaning groove 202 is flush with the bottom wall of the groove 201, and the cleaning groove 202 is provided through the groove 201 to form a mating groove on the rear side wall of the groove 201. A sliding groove 203 extending into the groove 201 is provided on the opposite side wall of the cleaning groove 202 along its width direction. A limiting groove 204 communicating with the corresponding sliding groove 203 is provided on the upper side of the lower mold base 130 along its width direction.

[0051] The cleaning assembly includes a scraper 310 slidably disposed within a groove 201. To prevent the scraper 310 from interfering with the placement of the battery aluminum casing within the groove 201, when not in use, the scraper 310 is located in a mating groove on the rear side of the groove 201. Sliding blocks 601 are provided on both sides of the scraper 310, sliding within a sliding groove 203. Each sliding block 601 has a lever extending from a limiting groove 204. The sidewalls of the scraper 310 slidably fit against the sidewalls of the groove 201. The side wall of the slider 601 slides and fits against the side wall of the groove 203. Thus, when scraping debris in the groove 201, the operator moves the lever along the limiting groove 204 to drive the scraper 310 out of the mating groove, pushing the debris on the bottom wall of the groove 201 into the cleaning groove 202 to clean the debris in the groove 201. Then, the scraper 310 is slid back into the mating groove by the lever, and the battery aluminum shell punching operation can be performed again.

[0052] It should be noted that the limiting groove 204 is located on both sides of the groove 201, and the lever on it does not interfere with the cooperation between the upper mold assembly and the lower mold assembly. Specifically, the bottom wall of the groove 201 is provided with a through hole for the corresponding push rod 141 to extend into. The through holes of the groove 201 on different lower mold bases 130 correspond to the corresponding insertion slots 301, that is, adjusting the position of the push rod 141 can make it extend into the corresponding through hole. When the push rod 141 does not lift the aluminum battery shell, the lifting plate 140 descends so that the upper end of the pull rod 552 is located in the through hole. In order to avoid debris getting stuck in the through hole at this time, the upper end of the pull rod 552 forms a pull post 553 that is adapted to the through hole. The upper end of the pull post 553 is flush with the bottom wall of the groove 201, and the outer side wall of the pull post 553 slides against the side wall of the through hole to reduce debris getting stuck in the through hole, which would prevent the scraper 310 from scraping out the debris.

[0053] In this embodiment, the lever includes a grip portion 611 and a threaded portion 612. The threaded portion 612 passes through the limiting groove 204 and is threadedly connected to the corresponding slider 601. The lower end of the threaded portion 612 is provided with a rubber pad for pressing against the bottom wall of the slide groove 203. The slider 601 is provided with a threaded hole for the threaded portion 612 to be threadedly connected. Thus, by gripping the grip portion 611 to rotate the threaded portion 612 and make it rotate into the threaded hole, the lever can be installed on the corresponding slider 601, so that the operator can drive the scraper 310 to move by the lever.

[0054] In actual use, in order to keep the scraper 310 in the mating groove and prevent the scraper 310 from sliding and affecting the use of the lower mold assembly, when the scraper 310 is in the mating groove, the threaded part 612 is rotated by holding the grip part 611, so that the rubber pad at the lower end of the threaded part 612 presses against the bottom wall of the slide groove 203 to increase the friction between the two and make the scraper 310 less likely to slide. When it is necessary to make the scraper 310 slide, the threaded part 612 is rotated by holding the grip part 611 to release the pressure between the rubber pad and the bottom wall of the slide groove 203.

[0055] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
