For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0025] The present invention is further described below by way of embodiments in conjunction with the accompanying drawings.

[0026] like Figure 1-Figure 6 As shown, a battery shell aluminum end plate stamping device includes a stamping component 1 that can perform stamping processing on the end plate moved into position as needed, a spin-down component 2 that can drive the end plate loaded into the device to rotate and lift is arranged on the front side of the stamping component 1, and a plug-in component 3 that can conveniently install the end plate and make it move along a relatively fixed track in the device is arranged on one side of the spin-down component 2.

[0027] In this embodiment: the stamping assembly 1 includes a frame 101, a lower die 102 is fixedly installed in the frame 101, a hydraulic cylinder 103 is fixedly installed above the frame 101, the telescopic end of the hydraulic cylinder 103 is fixedly connected to a carrier plate 104, and the lower side of the carrier plate 104 is fixedly connected to an upper die 105; the lower die 102, the hydraulic cylinder 103 and some parts of the spin-down assembly 2 are installed through the frame 101, and the end plate located between the closed lower die 102 and the upper die 105 is punched into a desired shape, and the length change of the telescopic end of the hydraulic cylinder 103 is transmitted to the upper die 105 through the carrier plate 104, so that the upper die 105 can be raised and lowered relative to the lower die 102.

[0028] In this embodiment: the spin-down assembly 2 includes a bottom plate 201 fixedly connected to the frame 101, a curved plate 202 fixedly connected to the bottom plate 201, a curved frame 203 fixedly connected above the curved plate 202, a vertical rod 204 is arranged between the curved plate 202 and the curved frame 203, a clamping ring 205 is fixedly connected to the outer side of the vertical rod 204, a first spring 206 is arranged above the clamping ring 205, a rotating cylinder 207 is arranged on one side of the vertical rod 204, a carrier 208 is arranged between the vertical rod 204 and the telescopic end of the rotating cylinder 207, and a plug rod 209 is fixedly connected to the carrier 208;

[0029] The arc plate 202, the arc frame 203, the first spring 206, the carrier 208, and the insertion rod 209 are all slidably connected to the vertical rod 204, and an elliptical through groove is provided on the vertical rod 204;

[0030] The arc plate 202 and the rotary cylinder 207 are installed through the bottom plate 201, and the movable range of the vertical rod 204 on the bottom plate 201 is limited by the arc plate 202 and the arc frame 203. The first spring 206 whose movable range is limited by the clamp ring 205 provides certain support for the carrier 208. The insertion rod 209 that passes through the through groove of the vertical rod 204 limits the rotation of the carrier 208 relative to the vertical rod 204, so that the carrier 208 can only be lifted and lowered relative to the vertical rod 204. The rotary cylinder 207 drives the carrier 208 and the vertical rod 204 to rotate together around the axis of the telescopic end of the rotary cylinder 207 in the device, and at the same time, the carrier 208 is lifted and lowered relative to the vertical rod 204. The carrier 208 that can only be lifted and lowered relative to the vertical rod 204 can drive the vertical rod 204 to slide relative to the arc plate 202 and the arc frame 203 after its own rotation, so that the first spring 206 connected to the vertical rod 204 always provides support for the carrier 208.

[0031] In this embodiment: the plug-in assembly 3 includes a cantilevered piece that can be inserted into the hollow end plate to be punched to conveniently fix it in the device, a limiter that can automatically reset the cantilevered piece after it is lowered a certain distance in the plug-in assembly 3 when not subject to external force, and a movable piece that can adjust the initial position of the cantilevered piece according to the size of the hollow end plate. The movable piece includes a support rod 301 fixedly connected to one side of the spin-down assembly 2, and a limit plate 302 is fixedly connected between adjacent support rods 301. A bidirectional cylinder 303 is fixedly installed on one side of the spin-down assembly 2. The telescopic ends of the cylinder 303 are fixedly connected to the moving frame 304, the limiting member includes a limiting rod 305 fixedly installed in the moving frame 304, the outer side of the limiting rod 305 is movably connected to the second spring 306, a slider 307 is arranged above the second spring 306, the cantilever member includes a cantilever rod 308 fixedly connected to the slider 307, and a plug-in board 309 is fixedly connected between the cantilever rods 308; the support rod 301 is slidably connected to the moving frame 304, and the moving frame 304 and the limiting rod 305 are both slidably connected to the slider 307;

[0032] The movable range of the connected moving frame 304 is limited by the support rod 301 and the limit plate 302, the moving frame 304 is driven to slide relative to the support rod 301 by the two-way cylinder 303, the position of the slider 307 in the moving frame 304 is limited by the limit rod 305 and the second spring 306, and the slider 307 that is not subject to external force always has a tendency to move to the top of the moving frame 304, the cantilever rod 308 for installing the plug-in board 309 is installed through the slider 307, and the end plate to be stamped is plugged in through two plug-in boards 309 with adjustable distance, height and position, and driven to move in this device.

[0033] Working principle: When the device is installed and used for aluminum end plate stamping work related to battery shell production, after the lower die 102 and the upper die 105 are installed, and the cantilever rod 308 and the plug-in board 309 of appropriate length and size are selected and installed, the position and distance of the plug-in board 309 in the plug-in assembly 3 are adjusted by the two-way cylinder 303, so that the plug-in board 309 can be smoothly inserted into a certain depth in the hollow area of ​​the end plate, so that the plug-in board 309 stably supports the end plate to prevent the end plate from falling when the plug-in board 309 moves;

[0034] After the end plate is installed, the rotating cylinder 207 can be operated to adjust the position of the carrier 208, so that it drives the plug-in assembly 3 and the end plate to rotate 90 degrees counterclockwise and lower to a certain height, so that the end plate is suspended at a certain height above the lower mold 102. After that, the upper mold 105 can be driven to move downward toward the end plate through the operation of the hydraulic cylinder 103. After the upper mold 105 contacts the end plate, the upper mold 105 that continues to move downward will press the end plate vertically into the lower mold 102 until the lower mold 102 and the upper mold 105 are fully closed, thereby completing the stamping process of the end plate.

[0035] After the processing is completed, the hydraulic cylinder 103 can reset the upper mold 105. Since the second spring 306 has been compressed before, during the rising process of the upper mold 105, the second spring 306 will lift the slider 307, so that the slider 307 drives the stamped end plate to move up a certain distance with the upper mold 105 through the cantilever rod 308 and the plug-in plate 309. After the upper side of the slider 307 contacts the moving frame 304 again, the end plate will no longer be able to move up with the upper mold 105 that is still being reset. At this time, the rotating cylinder 207 can be made to work again, and the plug-in component 3 and the end plate separated from the lower mold 102 and the upper mold 105 are driven to rotate clockwise and rise through the carrier 208. After the plug-in component 3 and the end plate are reset to the initial position, the stamped end plate can be removed for subsequent processing.

[0036] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
