Description

Technical Field

[0001] This invention relates to the field of welding technology, specifically to a welding device for producing the casing of an air compressor. Background Technology

[0002] An air compressor, also known as an air pressurizer, is a machine that compresses air to increase gas pressure or transport gas. Air compressors come in three types: piston, centrifugal, and screw. An air compressor is a device similar in principle to a water pump used to compress gas. An electric motor drives the crankshaft inside the air compressor, which in turn drives the connecting rod to move the piston back and forth, causing changes in the volume within the cylinder. The air compressor provides the air source power and is the core equipment of a pneumatic system, the main body of an electromechanical air source device. It is a device that converts the mechanical energy of a prime mover into the pressure energy of gas, and is the air pressure generator for compressed air. Air compressors are one of the mechanical power devices, and with the continuous development of technology and the rapid progress of society, their applications are increasing. In the manufacturing of air compressors, the air tank shell is one of the important components. Welding is required when processing the air tank shell, therefore, welding equipment is needed.

[0003] Currently, traditional welding methods for gas tank shells are inconvenient because the welding tools cannot be adjusted, resulting in less flexible welding and slower welding speed. Furthermore, the gas tank shell needs to be rolled to weld the gaps, which makes the gas tank shell prone to displacement, leading to inaccurate welding and affecting the welding quality. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A welding device for producing the casing of an air compressor includes:

[0006] The machine body, and the frame fixedly installed on the side of the machine body surface, a square frame is fixedly connected to the side of the top of the machine body, and a feeding mechanism is installed in the middle of the top of the machine body;

[0007] A processing mechanism for welding the air tank on the air compressor, the processing mechanism being installed in the middle of the top of the frame;

[0008] The processing mechanism includes a hydraulic cylinder and a connecting plate. The hydraulic cylinder is installed in the middle of the top of the frame. The connecting plate is fixedly connected to the telescopic end of the hydraulic cylinder. A rotary driver is fixedly installed in the middle of the bottom of the connecting plate. A welding gun is hinged to the edge of the rotating end of the rotary driver. An electric telescopic rod is hinged to the side of the bottom of the rotating end of the rotary driver. A guide assembly is installed on the side of the bottom of the connecting plate. By extending and retracting the telescopic end of the hydraulic cylinder, the connecting plate can be moved downward and upward. With the connection of the rotary driver, the welding gun is moved, and the height of the welding gun can be adjusted so that the welding end of the welding gun is at a suitable height with the air compressor tank shell to be welded, thereby helping to avoid welding the air tank.

[0009] The feeding mechanism includes a rotating worktable and a circular limiting hole. The rotating worktable is rotatably installed at the middle of the top of the machine body. The circular limiting hole is opened at the edge of the rotating worktable surface. An arc-shaped elastic strip is fixedly connected to the position of the circular limiting hole at the edge of the rotating worktable. A clamping block is fixedly connected to the inner side of the arc-shaped elastic strip. A lifting component is installed at the bottom side of the rotating worktable.

[0010] Preferably, the telescopic end of the electric telescopic rod is hinged to the surface of the electric telescopic rod. Both the electric telescopic rod and the electric telescopic rod are installed at an angle. By applying a pulling force to the welding gun through the telescopic end of the electric telescopic rod, the welding gun can be rotated to adjust the angle. By extending the telescopic end of the electric telescopic rod, the welding gun can be pushed, thereby causing the welding gun to rotate outward. The angle can be adjusted by using the rotation of the welding gun.

[0011] The rotating end at the bottom of the rotary driver can be used to rotate the welding gun, which rotates along the circumference of the central axis of the rotary driver. This allows the gas tank shell to be welded in a circumferential direction, while the gas tank shell remains stationary, ensuring accurate welding.

[0012] Preferably, the guiding assembly includes a guiding base plate. The top of the guiding base plate and the bottom edge of the connecting plate are fixedly installed with screws, and the guiding base plate is installed directly above the square frame. A bending and pressing plate is fixedly connected to the middle of the surface of the guiding base plate, and a strip-shaped arc-shaped extension edge is fixedly connected to the edge of the surface of the bending and pressing plate. When the connecting plate is pushed downward by the extension of the telescopic end of the hydraulic cylinder, the guiding assembly is driven downward as the connecting plate moves downward. The guiding base plate can then move downward, allowing its bottom end to insert into the interior of the square frame. The surface of the guiding base plate fits against the inner wall of the square frame, and the square frame guides the guiding base plate, supporting the connecting plate. This allows the connecting plate to drive the rotary driver and welding gun to move downward smoothly, reducing the impact of vibration.

[0013] Preferably, the guide base plate is installed vertically, and there are two strip-shaped arc-shaped extension edges, which are symmetrically installed along the bending and extrusion plate.

[0014] Preferably, there are four circular limiting holes, and the four circular limiting holes are evenly distributed at the edge of the rotating worktable surface. The circular limiting holes, the arc-shaped elastic strip, and the clamping block are installed at the same height.

[0015] Preferably, the lifting assembly includes a connecting shaft and a crescent-shaped lifting plate. The connecting shaft is rotatably mounted on the side of the bottom of the rotating worktable. The crescent-shaped lifting plate is fixedly connected to the bottom end of the connecting shaft. A torque spring is fixedly installed between the top of the crescent-shaped lifting plate and the side of the bottom of the rotating worktable. A right-angled rod is fixedly connected to the side of the surface of the crescent-shaped lifting plate. A cylinder is rolled on the surface of the right-angled rod at the end away from the crescent-shaped lifting plate. By vertically inserting the gas tank shell to be welded into the circular limiting hole, and by having the bottom of the gas tank shell contact the top of the crescent-shaped lifting plate, the gas tank shell can be supported and lifted by the crescent-shaped lifting plate, thus initially limiting the position of the gas tank shell.

[0016] Preferably, the crescent-shaped lifting plate is installed directly below the circular limiting hole, and there are four crescent-shaped lifting plates, which are evenly installed on the bottom of the rotating worktable, and the right-angled rod is installed vertically.

[0017] As the rotary worktable rotates, it moves the gas tank shell within the circular limit hole, allowing for loading. When the gas tank shell moves directly below the rotary driver, rotation pauses. Simultaneously, the arc-shaped elastic strip contacts the extended edge of the arc surface, and the rotation of the rotary worktable causes the arc-shaped elastic strip to be squeezed by the bending extrusion plate. The elasticity of the arc-shaped elastic strip allows the surface of the clamping block to fit against the outer circular surface of the gas tank shell, thus clamping and fixing the gas tank shell, preventing displacement and further facilitating welding of the gas tank shell.

[0018] Preferably, the torque spring is conical, and the connecting shaft passes through the center of the torque spring. The right-angled rod and the crescent-shaped lifting plate are installed at the same height. By rotating the worktable again, the welded gas tank shell can be removed, and the unwelded gas tank shell blank can be rotated for reloading, which is conducive to mass production. Furthermore, the arc-shaped elastic strip separates from the bending and extrusion plate. The bending and extrusion plate uses its own elasticity to drive the clamping block to move outward, which can release the gas tank shell.

[0019] Preferably, a receiving mechanism is installed on the side of the machine body surface. The receiving mechanism includes a support frame, which is fixedly connected to the side of the machine body surface by screws. A guide plate is fixedly connected to the top of the support frame. A bending baffle is fixedly connected to the side of the surface of the guide plate. An arc-shaped actuating strip is fixedly connected to the top side of the bending baffle. An elastic buffer membrane is fixedly connected to the inner side of the bending baffle, and the elastic buffer membrane is installed directly below the arc-shaped actuating strip. The cylinder contacts the arc-shaped actuating strip. As the rotating worktable continues to rotate, the arc-shaped actuating strip applies a pushing force to the cylinder. Under the rotational connection of the connecting shaft, the crescent-shaped lifting plate rotates counterclockwise. The crescent-shaped lifting plate moves out from directly below the circular limiting hole. The torque spring is elastically deformed by the torque force, causing the gas tank shell in the circular limiting hole to slide down for automatic unloading.

[0020] As the cylinder separates from the arc-shaped actuating bar, the pushing force on the cylinder disappears, and under the elastic force of the torque spring, the connecting shaft drives the crescent-shaped lifting plate to rotate in the opposite direction to reset, which facilitates the support and lifting of the new gas tank shell blank and helps with mass production.

[0021] Preferably, the guide plate is installed at an angle, and there are two bending baffles, which are symmetrically installed along the central axis of the guide plate. The surface of the elastic buffer membrane is wavy. As the gas tank shell slides down onto the elastic buffer membrane, it receives the gas tank shell and achieves flexible contact, providing buffer protection for the gas tank shell and making it less susceptible to damage. The angled installation of the guide plate allows the gas tank shell to slide down.

[0022] This invention provides a welding device for producing housings in air compressor manufacturing. It offers the following advantages:

[0023] The welding equipment for producing the housing of this air compressor uses the extension and retraction of the hydraulic cylinder to move the connecting plate downwards and upwards. With the connection of the rotary driver, the welding gun is moved, and the height of the welding gun can be adjusted so that the welding end of the welding gun is at a suitable height with the air compressor tank housing to be welded, thus helping to avoid welding the tank.

[0024] 2. The welding equipment for producing the housing of the air compressor moves downward by a guide plate, so that the bottom end of the guide plate is inserted into the inside of the square frame. The surface of the guide plate is in contact with the inner wall of the square frame. The square frame guides the guide plate, so that the connecting plate is supported by the guide plate. This allows the connecting plate to drive the rotary driver and the welding gun to move downward smoothly as a whole, reducing the impact of vibration.

[0025] 3. The welding equipment for producing the casing of the air compressor can apply a pulling force to the welding gun through the telescopic end of the electric telescopic rod, and the welding gun can be rotated and its angle adjusted by hinged with the rotating end of the rotary driver at the top of the welding gun. The extension of the telescopic end of the electric telescopic rod can push the welding gun, thereby causing the welding gun to rotate outward. The angle can be adjusted by using the rotation of the welding gun.

[0026] IV. The welding equipment for producing the housing of the air compressor uses the rotating end at the bottom of the rotary drive to rotate, which drives the welding gun to rotate as well. The welding gun rotates along the circumferential direction of the central axis of the rotary drive, so that the air tank housing to be welded can be welded in the circumferential direction. The air tank housing always remains stationary, which makes the welding accurate.

[0027] 5. The welding equipment for producing the housing of the air compressor can initially limit the position of the air tank by vertically inserting the air tank housing to be welded into the circular limiting hole and by having the bottom of the air tank housing contact the top of the crescent-shaped lifting plate.

[0028] VI. The welding equipment for producing the housing of the air compressor can pause rotation when the air tank housing is moved directly below the rotary drive. At the same time, the arc-shaped elastic strip contacts the extended edge of the arc-shaped surface, and under the rotation of the rotating worktable, the arc-shaped elastic strip is squeezed by the bending extrusion plate. Through the elasticity of the arc-shaped elastic strip, the surface of the clamping block is made to fit against the outer circular surface of the air tank housing, thus clamping and fixing the air tank housing, making it less prone to displacement.

[0029] VII. The welding equipment used for the production of the air compressor housing can rotate the worktable again to remove the welded air tank housing and rotate the unwelded air tank housing blank for reloading, which is conducive to mass production. In addition, the arc-shaped elastic strip separates from the bending extrusion plate. The bending extrusion plate drives the clamping block to move outward through its own elasticity, which can loosen the air tank housing.

[0030] 8. The welding equipment for producing the casing of the air compressor uses an arc-shaped actuating bar to apply a pushing force to the cylinder, causing the crescent-shaped lifting plate to rotate counterclockwise. The crescent-shaped lifting plate moves out from directly below the circular limiting hole, and the torque spring is subjected to torque force to undergo elastic deformation, causing the air tank casing in the circular limiting hole to slide down for automatic unloading.

[0031] 9. The welding equipment used for the production of the air compressor housing, as the cylinder separates from the arc-shaped actuating strip, the pushing force on the cylinder disappears, and under the elastic force of the torque spring, the connecting shaft drives the crescent-shaped lifting plate to rotate in the opposite direction to reset, which facilitates the support and lifting of the new air tank housing blank and helps to carry out mass production.

[0032] 10. The welding equipment for producing the shell of the air compressor receives the air tank shell as it slides down onto the elastic buffer membrane, achieving flexible contact and providing buffer protection for the air tank shell, making it less susceptible to damage. Furthermore, the inclined installation of the guide plate allows the air tank shell to slide down. Attached Figure Description

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] First embodiment, such as Figures 1 to 4 As shown, the present invention provides a technical solution:

[0044] A welding device for producing the casing of an air compressor includes:

[0045] The machine body 1, and the frame 2 fixedly installed on the side of the surface of the machine body 1, a square frame 3 fixedly connected to the side of the top of the machine body 1, and a feeding mechanism 4 installed in the middle of the top of the machine body 1.

[0046] The machining mechanism 5 is used to weld the air tank on the air compressor. The machining mechanism 5 is installed in the middle of the top of the frame 2.

[0047] The processing mechanism 5 includes a hydraulic cylinder 51 and a connecting plate 52. The hydraulic cylinder 51 is installed in the middle of the top of the frame 2. The connecting plate 52 is fixedly connected to the telescopic end of the hydraulic cylinder 51. A rotary driver 53 is fixedly installed in the middle of the bottom of the connecting plate 52. A welding gun 54 is hinged to the edge of the rotating end of the rotary driver 53. An electric telescopic rod 55 is hinged to the side of the bottom of the rotating end of the rotary driver 53. A guide assembly 56 is installed on the side of the bottom of the connecting plate 52. When the operator starts the hydraulic cylinder 51, the telescopic end of the hydraulic cylinder 51 is extended and retracted, which can drive the connecting plate 52 to move downward and upward. With the connection of the rotary driver 53, the welding gun 54 is moved, and the height of the welding gun 54 can be adjusted so that the welding end of the welding gun 54 is at a suitable height with the air compressor tank shell to be welded.

[0048] The telescopic end of the electric telescopic rod 55 is hinged to the surface of the electric telescopic rod 55. Both the electric telescopic rod 55 and the electric telescopic rod 55 are installed at an angle. When the operator opens the electric telescopic rod 55 to retract it, the telescopic end of the electric telescopic rod 55 can apply a pulling force to the welding gun 54. Combined with the hinge between the telescopic end of the welding gun 54 and the rotating end of the top rotary driver 53, the welding gun 54 can be rotated to adjust the angle. The extension of the telescopic end of the electric telescopic rod 55 can push the welding gun 54, thereby causing the welding gun 54 to rotate outward. The angle can be adjusted by using the rotation of the welding gun 54.

[0049] The rotary driver 53 is started and rotated by the rotating end at the bottom of the rotary driver 53, which drives the welding gun 54 to rotate together. The welding gun 54 rotates along the circumferential direction of the central axis of the rotary driver 53, and welds the gas tank shell that needs to be welded along the circumferential direction.

[0050] The guide assembly 56 includes a guide base plate 561. The top of the guide base plate 561 is fixedly installed to the bottom edge of the connecting plate 52 by screws. The guide base plate 561 is installed directly above the square frame 3. A bending extrusion plate 562 is fixedly connected to the middle of the surface of the guide base plate 561. A strip-shaped arc-shaped extension edge 563 is fixedly connected to the edge of the surface of the bending extrusion plate 562. When the connecting plate 52 is pushed downward by the extension of the telescopic end of the hydraulic cylinder 51, the guide assembly 56 is driven downward as the connecting plate 52 moves downward. The guide base plate 561 can then move downward, so that the bottom end of the guide base plate 561 is inserted into the interior of the square frame 3. The surface of the guide base plate 561 is in contact with the inner wall of the square frame 3. The square frame 3 guides the guide base plate 561, so that the connecting plate 52 is supported by the guide base plate 561. This allows the connecting plate 52 to drive the rotary driver 53 and the welding gun 54 to move downward smoothly as a whole.

[0051] The guide plate 561 is installed vertically, and there are two strip-shaped arc-shaped extension edges 563, which are symmetrically installed along the bent extrusion plate 562.

[0052] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 1 to 6 As shown:

[0053] The feeding mechanism 4 includes a rotating worktable 41 and a circular limiting hole 42. The rotating worktable 41 is rotatably installed at the middle of the top of the machine body 1. The circular limiting hole 42 is opened at the edge of the surface of the rotating worktable 41. An arc-shaped elastic strip 43 is fixedly connected to the position of the circular limiting hole 42 at the edge of the rotating worktable 41. A clamping block 44 is fixedly connected to the inner side of the arc-shaped elastic strip 43. A lifting assembly 45 is installed on the side of the bottom of the rotating worktable 41.

[0054] There are four circular limiting holes 42, and the four circular limiting holes 42 are evenly distributed at the edge of the surface of the rotating worktable 41. The circular limiting holes 42, the arc-shaped elastic strip 43 and the clamping block 44 are installed at the same height.

[0055] The lifting assembly 45 includes a connecting shaft 451 and a crescent-shaped lifting plate 452. The connecting shaft 451 is rotatably mounted on the side of the bottom of the rotating worktable 41. The crescent-shaped lifting plate 452 is fixedly connected to the bottom end of the connecting shaft 451. A torque spring 453 is fixedly installed between the top of the crescent-shaped lifting plate 452 and the side of the bottom of the rotating worktable 41. A right-angled rod 454 is fixedly connected to the side of the surface of the crescent-shaped lifting plate 452. A cylinder 455 is rolled on the surface of the right-angled rod 454 at the end away from the crescent-shaped lifting plate 452. By vertically inserting the gas tank shell to be welded into the circular limiting hole 42, and by having the bottom of the gas tank shell contact the top of the crescent-shaped lifting plate 452, the gas tank shell can be supported and lifted by the crescent-shaped lifting plate 452, thus initially limiting the gas tank shell.

[0056] The crescent-shaped lifting plate 452 is installed directly below the circular limiting hole 42. There are four crescent-shaped lifting plates 452, and the four crescent-shaped lifting plates 452 are evenly installed at the bottom of the rotating worktable 41. The right-angle rod 454 is installed vertically.

[0057] As the rotating worktable 41 rotates, it can move the gas tank shell inside the circular limiting hole 42, allowing the gas tank shell to be loaded. When the gas tank shell moves directly below the rotating drive 53, the rotation can be paused. At the same time, the arc-shaped elastic strip 43 contacts the extended edge 563 of the arc surface. Under the rotation of the rotating worktable 41, the arc-shaped elastic strip 43 is squeezed by the bending extrusion plate 562. Through the elasticity of the arc-shaped elastic strip 43, the surface of the clamping block 44 fits against the outer circular surface of the gas tank shell, thus clamping and fixing the gas tank shell.

[0058] The torque spring 453 is conical, and the connecting shaft 451 passes through the center of the torque spring 453. The right-angle rod 454 and the crescent-shaped lifting plate 452 are installed at the same height. After the gas tank shell is welded, the worktable 41 can be rotated again to remove the welded gas tank shell and rotate the unwelded gas tank shell blank for reloading, which is helpful for mass production. The arc-shaped elastic strip 43 is separated from the bending and pressing plate 562. The bending and pressing plate 562 drives the clamping block 44 to move outward through its own elasticity, releasing the gas tank shell.

[0059] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 1 to 8 As shown:

[0060] A material receiving mechanism 6 is installed on the side of the surface of the machine body 1. The material receiving mechanism 6 includes a support frame 61, which is fixedly connected to the side of the surface of the machine body 1 by screws. A guide plate 62 is fixedly connected to the top of the support frame 61. A bending baffle 63 is fixedly connected to the side of the surface of the guide plate 62. An arc-shaped actuating strip 64 is fixedly connected to the top side of the bending baffle 63. An elastic buffer membrane 65 is fixedly connected to the inner side of the bending baffle 63 and is installed on the arc-shaped actuating strip 64. Directly below, the cylinder 455 contacts the arc-shaped actuating bar 64. As the rotating worktable 41 continues to rotate, the arc-shaped actuating bar 64 applies a pushing force to the cylinder 455. Under the rotational connection of the connecting shaft 451, the crescent-shaped lifting plate 452 rotates counterclockwise. The crescent-shaped lifting plate 452 moves out from directly below the circular limiting hole 42. The torque spring 453 is elastically deformed by the torque force, causing the gas tank shell inside the circular limiting hole 42 to slide down for automatic unloading.

[0061] As the cylinder 455 separates from the arc-shaped actuating bar 64, the pushing force on the cylinder 455 disappears, and under the elastic force of the torque spring 453, the connecting shaft 451 drives the crescent-shaped lifting plate 452 to rotate in the opposite direction to reset, which facilitates the support and lifting of the new gas tank shell blank.

[0062] The guide plate 62 is installed at an angle, and there are two bent baffles 63, which are symmetrically installed along the central axis of the guide plate 62. The surface of the elastic buffer membrane 65 is wavy. As the gas tank shell slides down onto the elastic buffer membrane 65, it receives the gas tank shell and achieves flexible contact, providing buffer protection for the gas tank shell and making it less susceptible to damage. The inclined installation of the guide plate 62 allows the gas tank shell to slide down.

[0063] In use, the gas tank shell to be welded is first vertically placed into the circular limiting hole 42, and the bottom of the gas tank shell is in contact with the top of the crescent lifting plate 452. The crescent lifting plate 452 can then support and lift the gas tank shell, thus initially limiting its position.

[0064] At this time, the operator starts the hydraulic cylinder 51 to work. The extension end of the hydraulic cylinder 51 is used to extend the connecting plate 52 downward. Under the connection of the rotary driver 53, the welding gun 54 is moved to adjust the height of the welding gun 54 so that the welding end of the welding gun 54 is at a suitable height with the air compressor storage tank shell to be welded.

[0065] Simultaneously, when the connecting plate 52 is pushed downward by the extension of the telescopic end of the hydraulic cylinder 51, as the connecting plate 52 moves downward, the guide assembly 56 is driven to move downward as a whole. It can then move downward through the guide plate 561, so that the bottom end of the guide plate 561 is inserted into the interior of the square frame 3. By using the surface of the guide plate 561 to fit against the inner wall of the square frame 3, and by the guidance of the square frame 3 on the guide plate 561, the connecting plate 52 is supported by the guide plate 561, thereby causing the connecting plate 52 to drive the rotary driver 53 and the welding gun 54 to move downward smoothly as a whole.

[0066] As the rotating worktable 41 rotates, the gas tank shell inside the circular limiting hole 42 can be moved, allowing the gas tank shell to be loaded. When the gas tank shell moves directly below the rotary driver 53, the rotation can be paused. At the same time, the arc-shaped elastic strip 43 contacts the extended edge 563 of the arc surface, and under the rotation of the rotating worktable 41, the arc-shaped elastic strip 43 is squeezed by the bending extrusion plate 562. Through the elasticity of the arc-shaped elastic strip 43, the surface of the clamping block 44 fits against the outer circular surface of the gas tank shell, thus clamping and fixing the gas tank shell.

[0067] Furthermore, when the staff activates the electric telescopic rod 55 to retract it, the extension end of the electric telescopic rod 55 can apply a pulling force to the welding gun 54. Combined with the hinge between the rotating end of the rotating driver 53 at the top of the welding gun 54, the welding gun 54 can be rotated to adjust the angle. The extension of the extension end of the electric telescopic rod 55 can push the welding gun 54, thereby causing the welding gun 54 to rotate outward. The angle can be adjusted by the rotation of the welding gun 54.

[0068] The rotary driver 53 is started and operated. The rotating end at the bottom of the rotary driver 53 is rotated, which drives the welding gun 54 to rotate together. The welding gun 54 rotates along the circumferential direction of the central axis of the rotary driver 53, and welds the gas tank shell that needs to be welded along the circumferential direction.

[0069] After the gas tank shell is welded, the worktable 41 can be rotated again to remove the welded gas tank shell and rotate the unwelded gas tank shell blank for reloading, which helps with mass production. The arc-shaped elastic strip 43 separates from the bending and pressing plate 562. The bending and pressing plate 562 uses its own elasticity to drive the clamping block 44 to move outward and loosen the gas tank shell.

[0070] Furthermore, by utilizing the contact between the cylinder 455 and the arc-shaped actuating bar 64, and with the continuous rotation of the rotating worktable 41, the arc-shaped actuating bar 64 applies a pushing force to the cylinder 455. Under the rotational connection of the connecting shaft 451, the crescent-shaped lifting plate 452 rotates counterclockwise. As the crescent-shaped lifting plate 452 moves out from directly below the circular limiting hole 42, the torque spring 453 undergoes elastic deformation under the torque force, causing the gas storage tank shell inside the circular limiting hole 42 to slide downwards for automatic unloading.

[0071] As the cylinder 455 separates from the arc-shaped actuating bar 64, the pushing force on the cylinder 455 disappears, and under the elastic force of the torque spring 453, the connecting shaft 451 drives the crescent lifting plate 452 to rotate in the opposite direction to reset, which facilitates the support and lifting of the new gas tank shell blank.

[0072] As the gas tank shell slides down onto the elastic buffer membrane 65, it receives the material and achieves flexible contact, providing buffer protection for the gas tank shell and making it less susceptible to damage. Furthermore, the inclined installation of the guide plate 62 allows the gas tank shell to slide down.
