[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0032] Refer to Figure 1 、 Figure 3 and Figure 5, an embodiment provided by the present utility model: a multi-stage stepped stretching vacuum bottle aluminum shoulder sleeve forming device, comprising a bottom plate 1, a second connecting rod 14 and a transmission belt 25. A plurality of hollow bases 3 are arranged on the upper side of the bottom plate 1, and the lower hollow base 3 is fixedly connected to the top of the bottom plate 1. A servo motor 4 is fixedly connected to the inner bottom of the lower hollow base 3. The inner top of the upper hollow base 3 is rotatably connected to a movable rod 5. The output end of the servo motor 4 and the adjacent end of the movable rod 5 are both fixedly connected with a driving gear 6. The left and right ends of the inner sides of the two hollow bases 3 away from each other are rotatably connected with a rotating rod 7. One end of the rotating rod 7 is fixedly connected with a driven gear 8. A plurality of driven gears 8 are respectively meshed and connected with the left and right sides of the corresponding driving gears 6. One side of the driven gear 8 is fixedly connected with a fixed rod 9. One end of the fixed rod 9 is rotatably connected with a first movable shaft 10. The left and right ends of the adjacent sides of the two hollow bases 3 are respectively provided with a limiting groove 11. A limiting block 12 is slidably connected inside the limiting groove 11. One side of the limiting block 12 is rotatably connected with a second movable shaft 13. A plurality of second movable shafts 13 are respectively connected to the corresponding first movable shafts 10 through a second connecting rod 14. The other side of the limiting block 12 is fixedly connected with an arc-shaped clamping plate 15. An upper mold 20 is arranged between the two upper arc-shaped clamping plates 15. The middle of the top end of the lower hollow base 3 is provided with a lower mold 17. A transmission assembly is arranged on the right side of the top of the bottom plate 1. The transmission assembly includes a hollow column 21. The hollow column 21 is rotatably connected to the right side of the top of the bottom plate 1. An activity column 22 is slidably connected inside the hollow column 21. The top end of the activity column 22 is rotatably connected to the bottom of a support plate 26. The outer sides of the activity column 22 and the hollow column 21 are both fixedly connected with a first pulley 23. The outer side of the right rotating rod 7 is fixedly connected with a second pulley 24. A groove 28 is arranged on the right side of the hollow base 3. The two first pulleys 23 are respectively in transmission connection with the corresponding second pulleys 24 through a transmission belt 25. A jacking mechanism 2 is arranged inside the lower mold 17. The jacking mechanism 2 is used to facilitate the taking out of the processed aluminum shoulder sleeve. The sizes of the plurality of limiting blocks 12 respectively match the internal sizes of the corresponding limiting grooves 11. The placement position of the upper mold 20 corresponds to the placement position of the lower mold 17;

[0033] Specifically, the servo motor 4 can drive the rotation of the driving gear 6 outside its output end. The driving gear 6 will drive the rotation of the meshing driven gear 8. During this process, the first movable shaft 10 located at the top of the driven gear 8 starts to rotate. Through the connection of the second connecting rod 14, the second movable shaft 13 will also rotate accordingly. This rotational movement can drive the arc-shaped clamping plate 15 to move towards both sides inside the corresponding limiting groove 11, thereby realizing the release of the limiting and fixing of the lower mold 17. At the same time, when one of the driven gears 8 starts to rotate, its corresponding rotating rod 7 will also rotate accordingly, which can drive the second pulley 24 to start rotating. The first pulley 23 on the hollow column 21 is connected to the hollow column 21 through the transmission belt 25. Therefore, the hollow column 21 will also start to rotate. During this rotation process, the movable column 22 inside the hollow column 21 will also start to rotate and drive the first pulley 23 on its outer side to rotate. The connected second pulley 24 will also rotate through the transmission belt 25, thereby driving the rotation of a driven gear 8 on the upper side. This rotation will cause the driving gear 6 meshing with it to also rotate accordingly. In this way, the arc-shaped clamping plates 15 on both sides can move inside the corresponding limiting grooves 11, thereby releasing the limiting and fixing of the upper mold 20. Through this design, the disassembly and replacement of the upper mold 20 and the lower mold 17 are relatively simple, thereby reducing the workload of the staff.

[0034] Refer to Figure 2 and Figure 4 , the jacking mechanism 2 includes a cavity 201 and a first connecting rod 207. The cavity 201 is opened inside the lower mold 17. The left side of the lower mold 17 is rotatably connected with a bidirectional lead screw 202. The right end of the bidirectional lead screw 202 penetrates through the cavity 201. Both the left and right sides of the outer wall of the bidirectional lead screw 202 are threadedly connected with movable blocks 203. The top of the movable block 203 is rotatably connected with a first rotating shaft 204. The inner bottom of the lower mold 17 is provided with a top plate 205. Both the left and right sides of the bottom of the top plate 205 are rotatably connected with second rotating shafts 206. The two second rotating shafts 206 are respectively connected to the corresponding first rotating shafts 204 through the first connecting rod 207. The jacking mechanism 2 further includes slide rods 208. The two slide rods 208 are respectively fixedly connected to the front and rear sides inside the cavity 201. The front and rear sides of the two movable blocks 203 are respectively slidably connected to the outer sides of the corresponding slide rods 208;

[0035] Specifically, rotating the bidirectional lead screw 202 can cause the movable blocks 203 on both sides of the device to move toward the middle along the outer side of the slide rod 208. During this process, the first rotating shaft 204 on the movable block 203 starts to rotate, and the second rotating shaft 206 connected to the first rotating shaft 204 through the first connecting rod 207 also rotates accordingly. At this time, the top plate 205 will be jacked up until the product on the top plate 205 is successfully separated from the lower mold 17. It is relatively simple for the staff to take the mold, and the set slide rod 208 can limit the movement track of the movable block 203, making it move more smoothly.

[0036] Referring to Figure 1 and Figure 2 , a rear side of the bottom plate 1 is fixedly connected with an L-shaped plate 18. A top portion inside the L-shaped plate 18 is fixedly connected with a hydraulic rod 19. One end of the hydraulic rod 19 is fixedly connected with a top of the corresponding hollow base 3. A front end of a right side of the top of the bottom plate 1 is fixedly connected with a controller 27. The controller 27 is electrically connected to the servo motor 4 and the hydraulic rod 19 respectively;

[0037] Specifically, the hydraulic rod 19 can drive the upper mold 20 to move downward to perform hydraulic forming on the aluminum material in the lower mold 17, and the set controller 27 can control the operations of the servo motor 4 and the hydraulic rod 19. The model of the servo motor 4 is MHMJ082G1U, and the model of the hydraulic rod 19 is YG150.

[0038] Referring to Figure 5 , one side of each of the multiple arc-shaped clamping plates 15 is fixedly connected with a rubber pad 16. Sizes of the multiple rubber pads 16 are respectively the same as sizes of the corresponding arc-shaped clamping plates 15;

[0039] Specifically, the rubber pads 16 can further increase the friction between the arc-shaped clamping plates 15 and the upper mold 20 and the lower mold 17, making them placed more stably.

[0040] Working principle: When using this device, first pour the aluminum material to be processed into the lower mold 17, and then drive the upper mold 20 to move downward through the hydraulic rod 19 to perform hydraulic forming on the aluminum material in the lower mold 17. During long-term use, the upper mold 20 and the lower mold 17 are prone to excessive wear. At this time, the servo motor 4 can drive the driving gear 6 on the outer side of its output end to rotate, and the driven gear 8 engaged with it will rotate accordingly. At this time, the first moving shaft 10 at the top of the driven gear 8 will rotate accordingly, and the second moving shaft 13 will also rotate through the second connecting rod 14, so as to drive the arc-shaped clamping plate 15 to move to both sides inside the corresponding limiting groove 11, and the limiting fixation of the lower mold 17 can be released. While one of the driven gears 8 rotates, the corresponding rotating rod 7 will rotate accordingly, so as to drive the second pulley 24 to rotate. The first pulley 23 on the hollow column 21 will rotate through the transmission belt 25, so as to drive the hollow column 21 to rotate. At the same time, the moving column 22 inside the hollow column 21 will also rotate to drive the first pulley 23 on its outer side to rotate. The second pulley 24 connected thereto will also rotate through the transmission belt 25, so as to drive one of the upper driven gears 8 to rotate, and the driving gear 6 engaged with it will also rotate accordingly. Similarly, the arc-shaped clamping plates 15 on both sides can move inside the corresponding limiting grooves 11, so as to release the limiting fixation of the upper mold 20. It is relatively simple to disassemble and replace the upper mold 20 and the lower mold 17;

[0041] And after the processing work is completed, rotating the bidirectional lead screw 202 can drive the moving blocks 203 on both sides to move towards the middle on the outer side of the sliding rod 208. At this time, the first rotating shaft 204 on the moving block 203 will rotate accordingly, and the second rotating shaft 206 will also rotate through the first connecting rod 207, so as to lift the top plate 205. The product on the top plate 205 will be separated from the lower mold 17, which is convenient for the staff to take the mold, thereby improving the practicability of this device.

[0042] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
