[0041] S5. Adjust the rotation of the adapter plate seat and adjust the extension and retraction of the spinning drive cylinder to complete the spinning forming process of the outer wall of the gas storage cylinder.

[0042] The spinning forming apparatus and method for producing aluminum alloy gas cylinders of the present invention have the following advantages over the prior art:

[0043] (1) The spinning forming device for producing aluminum alloy gas cylinders of this application can clamp the gas cylinder from the outside by setting an external spinning die and press the gas cylinder from the top with a top clamping frame to complete the clamping and fixing connection of the gas cylinder. After clamping and fixing, the inner wall of the gas cylinder can be spun by adjusting the rotation of the core mold. The gas cylinder can be pressed and fixed by setting a core mold to support the gas cylinder and pressing the gas cylinder from the top with a top clamping frame. After pressing and fixing, the outer wall of the gas cylinder can be spun by adjusting the rotation of the adapter plate and adjusting the extension and retraction of the spinning drive cylinder. The outer spinning die and the adapter cylinder can be driven by setting a transmission component to facilitate the clamping and fixing of the gas cylinder by the external spinning die together with the adapter cylinder, which is convenient to use.

[0044] (2) By setting the external rotating die to be inserted into the extension through the first connecting block, it is convenient for the external rotating die to drive the transmission plate to move together. At the same time, it is convenient to adjust the separation of the transmission plate and the external rotating die. By setting the second connecting block to be located below the assembly part and opposite to the second connecting slot, when it is necessary to separate the transmission plate and the external rotating die, it is only necessary to adjust the sliding top seat to slide upward. At this time, the second connecting block is inserted into the inside of the second connecting slot, and the sliding top seat lifts the transmission plate. This not only allows for quick adjustment of the separation of the transmission plate and the external rotating die, but also completes the connection between the sliding top seat and the transmission plate. After connection, the external rotating die can rotate, and the adapter cylinder is in a fixed state, which is convenient for use.

[0045] (3) By setting up a drive assembly, when the inner wall of the gas storage cylinder is spun using a core mold, the drive motor drives the third rotating shaft to rotate. At this time, the third rotating shaft drives the first drive gear to rotate, the first drive gear drives the second drive gear to rotate, the second drive gear drives the bottom shaft to rotate, and the bottom shaft drives the core mold to rotate through the adapter base, thus completing the spun forming process of the inner wall of the gas storage cylinder. When the outer wall of the gas storage cylinder needs to be spun using an external spun mold, the second adjusting cylinder drives the sliding base to slide away from the bottom shaft. At this time, the first drive gear and the second drive gear separate from each other, and the fourth inclined gear and the fifth inclined gear mesh with each other. At this time, the rotation of the third rotating shaft can drive the fourth rotating shaft to rotate through the fourth inclined gear and the fifth inclined gear. The fourth rotating shaft drives the third drive gear to rotate. The third drive gear drives the rotation of the adapter plate through meshing with the annular tooth groove, thus completing the rotation adjustment process of the external spun mold, which is convenient to use.

[0058] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0059] like Figures 1-10 As shown, the spinning forming apparatus for producing aluminum alloy gas cylinders of the present invention includes a base 1, a core mold 21, a transfer plate seat 22, a mounting support 23, a spinning drive cylinder 24, an outer spinning mold 25, a transfer cylinder 31, a top pressing frame 32, and a transmission assembly 4. The core mold 21 is rotatably mounted on the top of the base 1, and the gas cylinder 10 is sleeved on the core mold 21. The core mold 21 is used to spin the inner wall of the gas cylinder 10. The transfer plate seat 22 is rotatably mounted on the base 1, and the number of mounting supports 23 is at least two, both mounted on the transfer plate seat 22. The spinning process... The drive cylinder 24 is mounted on the mounting support 23, and the outer spinning die 25 is mounted on the telescopic end of the spinning drive cylinder 24 for spinning the outer wall of the gas storage cylinder 10; the adapter cylinder 31 is rotatably mounted above the core mold 21, and the top clamping frame 32 is mounted on the adapter cylinder 31 for rotating to press against the top wall of the gas storage cylinder 10; the transmission assembly 4 is located between the outer spinning die 25 and the adapter cylinder 31. When the outer spinning die 25 moves toward the core mold 21, the transmission assembly 4 drives the adapter cylinder 31 to rotate the top clamping frame 32 toward the core mold 21.

[0060] In practice, the gas cylinder 10 is fitted onto the top of the core mold 21, with a spinning gap between the gas cylinder 10 and the base 1. The spinning drive cylinder 24 is adjusted to extend closer to the core mold 21, at which point the outer spinning mold 25 presses against the outside of the gas cylinder 10. The outer spinning mold 25 drives the adapter cylinder 31 to rotate via the transmission assembly 4. The adapter cylinder 31 drives the top clamping frame 32 to rotate downward and press against the top of the gas cylinder 10, completing the clamping and positioning of the gas cylinder 10. The core mold 21 is adjusted to rotate, completing the spinning process on the inner wall of the gas cylinder 10. The transmission assembly 4 is adjusted to disengage from the outer spinning mold 25, and the top clamping frame 32 continues to press against the top of the gas cylinder 10. The adapter plate seat 22 is adjusted to rotate, and the spinning drive cylinder 24 is adjusted to extend and retract, completing the spinning forming process on the outer wall of the gas cylinder 10.

[0061] The spinning forming device for producing aluminum alloy gas cylinders disclosed in this application uses an external spinning die 25 to clamp the gas cylinder 10 from the outside, and a top clamping frame 32 to press the gas cylinder 10 down from the top, thus completing the clamping and fixing connection of the gas cylinder 10. After clamping and fixing, the inner wall of the gas cylinder 10 can be spun and formed by adjusting the rotation of the core die 21. The gas cylinder 10 can be pressed and fixed by the core die 21 supporting the gas cylinder 10 and the top clamping frame 32 pressing it down from the top. After pressing and fixing, the outer wall of the gas cylinder 10 can be spun and formed by adjusting the rotation of the adapter plate 22 and adjusting the extension and retraction of the spinning drive cylinder 24. The external spinning die 25 and the adapter cylinder 31 can be driven by the transmission component 4, which facilitates the clamping and fixing of the gas cylinder 10 by the external spinning die 25 together with the adapter cylinder 31, making it convenient to use.

[0062] In a preferred embodiment, the top clamping frame 32 includes a connecting frame 321 and a top clamping frame 322, wherein the connecting frame 321 is fixedly connected to the adapter cylinder 31, and the top clamping frame 322 is hinged to the end of the connecting frame 321, and a friction pad is provided on the bottom wall of the top clamping frame 322.

[0063] This design ensures that during the pressing of the top wall of the gas storage cylinder 10 by the top pressing frame 32, the hinge action of the top pressing frame 322 can ensure that the top pressing frame 32 is close to the top of the gas storage cylinder 10 to press the gas storage cylinder 10, thereby improving the pressing effect of the gas storage cylinder 10 and making it convenient to use.

[0064] In a preferred embodiment, the transmission assembly 4 includes a transmission gear 41, a first helical gear 42, a second helical gear 43, a third helical gear 44, and a transmission plate 45. The transmission gear 41 is rotatably disposed on one side of the adapter cylinder 31, and the first helical gear 42 is fixedly connected to the transmission gear 41. The second helical gear 43 is fixedly connected to the adapter cylinder 31, and the third helical gear 44 is rotatably disposed between the first helical gear 42 and the second helical gear 43, and is connected to the first helical gear 42 and the second helical gear 43 in a transmission connection. The transmission plate 45 is detachably connected to the external rotary mold 25, and the transmission plate 45 is provided with a transmission rack 46 that meshes with the transmission gear 41.

[0065] It also includes an external assembly frame 51, which is an L-shaped frame including a vertical frame 511 and a horizontal frame 512. The vertical frame 511 is fixedly connected to the base 1, and the horizontal frame 512 is provided with a first assembly hole 513 and a second assembly hole 514. A first rotating shaft 52 is rotatably provided inside the first assembly hole 513, and the adapter cylinder 31 and the second helical gear 43 are both provided on the first rotating shaft 52. A second rotating shaft 53 is rotatably provided inside the second assembly hole 514, and the transmission gear 41 and the first helical gear 42 are both provided on the second rotating shaft 53. A third helical gear 44 is rotatably connected to the top of the horizontal frame 512.

[0066] This design allows the transmission plate 45 to move along with the outer rotating die 25 during adjustment. The transmission plate 45, through its transmission rack 46, drives the transmission gear 41 to rotate. The transmission gear 41 then drives the first inclined gear 42 to rotate. The first inclined gear 42, through the third inclined gear 44, drives the second inclined gear 43 to rotate. The second inclined gear 43, through the adapter cylinder 31, drives the top clamping frame 32 to rotate, thus completing the rotation adjustment of the top clamping frame 32. By setting the third inclined gear 44 to drive the first inclined gear 42 and the second inclined gear 43, the first and second inclined gears 42 and 43 can rotate simultaneously in opposite directions. This allows the top clamping frame 32 to rotate synchronously downwards when the outer rotating die 25 is moved closer to the core die 21, facilitating its use.

[0067] In a preferred embodiment, the transmission plate 45 includes an assembly portion 451 and an extension portion 452, wherein the transmission rack 46 is disposed on the assembly portion 451, and the extension portion 452 abuts against the top of the outer rotary die 25. The outer rotary die 25 is provided with a first connecting plug 251, and the extension portion 452 is provided with a first connecting slot 4521 for the first connecting plug 251 to be inserted.

[0068] It also includes a sliding top seat 61, a second connecting block 62, and a first adjusting cylinder 63. The sliding top seat 61 is slidably disposed inside the second assembly hole 514 and slides in the height direction. The second connecting block 62 is disposed on the sliding top seat 61 and located below the assembly part 451. The bottom of the assembly part 451 is provided with a second connecting slot 4511 that is opposite to the second connecting block 62. The first adjusting cylinder 63 is disposed on the outer assembly frame 51 and is used to drive the sliding top seat 61 to slide.

[0069] By setting the outer rotating mold 25 to be inserted into the extension 452 via the first connecting block 251, it is convenient for the outer rotating mold 25 to drive the transmission plate 45 to move together, and at the same time, it is convenient to adjust the separation of the transmission plate 45 and the outer rotating mold 25. By setting the second connecting block 62 to be located below the assembly part 451 and opposite to the second connecting slot 4511, when it is necessary to separate the transmission plate 45 and the outer rotating mold 25, it is only necessary to adjust the sliding top seat 61 to slide upward. At this time, the second connecting block 62 is inserted into the interior of the second connecting slot 4511, and the sliding top seat 61 lifts the transmission plate 45. This not only quickly adjusts the separation of the transmission plate 45 and the outer rotating mold 25, but also completes the connection between the sliding top seat 61 and the transmission plate 45. After connection, the outer rotating mold 25 can rotate, and the adapter cylinder 31 is in a fixed state for convenient use.

[0070] Preferably, both the first connecting block 251 and the second connecting block 62 are rectangular blocks. This design ensures that after the first connecting block 251 and the second connecting block 62 are inserted into the transmission plate 45, the transmission plate 45 can be prevented from rotating unexpectedly.

[0071] In a preferred embodiment, the system further includes an adapter base 71, a bottom shaft 72, and a drive assembly 8. The adapter base 71 is rotatably mounted on the base 1, and the core mold 21 is mounted on the adapter base 71. The bottom shaft 72 is fixedly connected to the adapter base 71 and extends to the bottom of the base 1. The drive assembly 8 is used to selectively drive the bottom shaft 72 and the adapter plate 22 to rotate.

[0072] The drive assembly 8 includes a sliding base 81, a third rotating shaft 82, a drive motor 83, a first drive gear 84, and a second drive gear 85. The sliding base 81 is slidably disposed on the base 1 and slides towards or away from the bottom shaft 72. The third rotating shaft 82 is rotatably disposed on the sliding base 81, and the drive motor 83 is disposed on the sliding base 81 to drive the third rotating shaft 82 to rotate. The first drive gear 84 is fixedly connected to the third rotating shaft 82, and the second drive gear 85 is fixedly connected to the bottom shaft 72. The first drive gear 84 and the second drive gear 85 mesh with each other.

[0073] The drive assembly 8 also includes a fourth helical gear 86, a fourth rotating shaft 87, a third drive gear 88, a fifth helical gear 89, and a second adjusting cylinder 810. The fourth helical gear 86 is mounted on the third rotating shaft 82. The fourth rotating shaft 87 is rotatably mounted on the bottom of the base 1, and both the third drive gear 88 and the fifth helical gear 89 are mounted on the fourth rotating shaft 87. The bottom of the base 1 has an assembly through hole 11 for the third drive gear 88 to pass through, and the bottom of the adapter plate 22 has an annular tooth groove 221 that meshes with the third drive gear 88. The fifth helical gear 89 is mounted on one end of the fourth rotating shaft 87 near the bottom shaft 72. When the sliding base 81 moves away from the bottom shaft 72, the fifth helical gear 89 meshes with the fourth helical gear 86. The second adjusting cylinder 810 is mounted on the base 1 and is used to drive the sliding base 81 to slide.

[0074] By setting the drive assembly 8, when the inner wall of the gas storage cylinder 10 is spun and formed by the mandrel 21, the drive motor 83 drives the third rotating shaft 82 to rotate. At this time, the third rotating shaft 82 drives the first drive gear 84 to rotate, the first drive gear 84 drives the second drive gear 85 to rotate, the second drive gear 85 drives the bottom shaft 72 to rotate, and the bottom shaft 72 drives the mandrel 21 to rotate through the adapter base 71, thus completing the spun and forming process of the inner wall of the gas storage cylinder 10. When the outer wall of the gas storage cylinder 10 needs to be spun and formed by the external spun die 25, the sliding base 81 is driven to slide away from the bottom shaft 72 by the second adjusting cylinder 810. At this time, the first driving gear 84 and the second driving gear 85 are separated, and the fourth inclined gear 86 and the fifth inclined gear 89 are meshed. The rotation of the third rotating shaft 82 can drive the fourth rotating shaft 87 to rotate through the fourth inclined gear 86 and the fifth inclined gear 89. The fourth rotating shaft 87 drives the third driving gear 88 to rotate. The third driving gear 88 drives the rotation of the adapter plate 22 by meshing with the annular tooth groove 221, thus completing the rotation adjustment of the external spun die 25, which is convenient to use.

[0075] This invention also proposes a spinning forming method for producing aluminum alloy gas cylinders, which is completed using the aforementioned spinning forming device for producing aluminum alloy gas cylinders, and includes the following steps:

[0076] Step 1: Fit the air storage cylinder 10 onto the top of the core mold 21. At this time, there is a spinning gap between the air storage cylinder 10 and the base 1.

[0077] Step 2: Adjust the spinning drive cylinder 24 to extend towards the core mold 21. At this time, the outer spinning die 25 presses against the outside of the air storage cylinder 10, and the outer spinning die 25 drives the adapter cylinder 31 to rotate through the transmission component 4. The adapter cylinder 31 drives the top clamping frame 32 to rotate downward and press against the top of the air storage cylinder 10, thus completing the clamping and positioning process of the air storage cylinder 10.

[0078] Step 3: Adjust the rotation of the core mold 21 to complete the spinning treatment of the inner wall of the gas storage cylinder 10;

[0079] Step 4: Adjust the transmission assembly 4 to disengage from the outer rotating mold 25, and keep the top clamping frame 32 pressing against the top of the gas storage cylinder 10.
