When the lower roller presses the cylinder upward to flanging, the upper roller presses the cylinder downward. The lower roller and the upper roller are aligned, forming a closed force loop, which avoids uneven force on the cylinder surface. At the same time, both ends of the cylinder abut against a fixed sleeve, symmetrically limiting the cylinder and increasing the stability of the cylinder during rotation. When the lower roller presses the cylinder upward, the third... The second spring inside the connecting rod extends and pushes the extrusion ring against the side wall of the cylinder. During the movement of the lower roller, the second spring inside the first connecting rod extends and retracts, changing the height of the second connecting rod and the extrusion ring, thereby ensuring that the distance between the extrusion ring and the second support rod remains unchanged, so that the extrusion ring is located above the lower roller, and the distance between the two is small. The contact point between the extrusion ring and the cylinder is located directly above the flange position. The lower roller extrudes the cylinder from the inside out, and the extrusion ring extrudes the cylinder from the outside in, protecting the side wall of the cylinder above the flange position. The side wall of the extrusion ring is arc-shaped to increase the contact area with the cylinder, thereby reducing the occurrence rate of cylinder flange wrinkles. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please see Figures 1 to 5 , Figure 1 A schematic diagram of a preferred embodiment of the flange-flanging device for thin-walled circular containers provided by this utility model; Figure 2 for Figure 1 The diagram shows an enlarged view of the structure at point A. Figure 3 for Figure 1 The top view of the support platform structure shown; Figure 4 for Figure 1 The diagram shows the internal structure of the mounting plate. Figure 5 for Figure 4The diagram shows a clamping structure. A flanged device for a thin-walled circular container includes a support platform 1, a clamp 7 mounted on the surface of the support platform 1, and a cylinder 5 mounted on the surface of the clamp 7. A rotating mechanism 2 and a driving mechanism 3 are installed inside the support platform 1. The clamp 7 includes a fixed column 71, the top of which is fixedly connected to the fixed column 71. Multiple sliding cylinders 75 are installed inside the fixed column 71, and the sliding cylinders 75 communicate with the support column 23. A sealing ring is installed at the connection between the support column 23 and the base 25 to prevent oil leakage. A piston 74 and a sliding rod 76 are slidably connected inside the sliding cylinder 75. The two ends of the sliding rod 76 are fixedly connected to the piston 74 and a fixing plate 72, respectively. The fixing plate 72, with its arc-shaped sidewall, abuts against the inner sidewall of the cylinder 5. A first spring 73 is fitted onto the sidewall of the sliding rod 76, and the two ends of the first spring 73 abut against the piston 74 and the sliding cylinder 75, respectively. The drive mechanism 3 includes an oil tank 31, which is installed inside the support platform 1. A hydraulic pump 32 is installed inside the oil tank 31. The two ends of the oil outlet pipe 33 are connected to the hydraulic pump 32 and the base 25, respectively. The two ends of the oil return pipe 34 are connected to the oil tank 31 and the base 25, respectively. When the cylinder 5 is placed on the side wall of the fixed plate 72, the hydraulic pump 32 operates, the valve on the side wall of the oil outlet pipe 33 opens, and the hydraulic pump 32 pumps the hydraulic oil inside the oil tank 31 into the interior of the slide cylinder 75 through the oil outlet pipe 33 and the support column 23. This pushes the piston 74 and the slide rod 76 to move inside the slide cylinder 75 and compress the first spring 73. The slide rod 76 pushes the fixed plate 72 to move outward, so that the fixed plate 72 is tightly attached to the inner side wall of the cylinder 5, thus fixing the cylinder 5. When it is necessary to untie the cylinder 5, open the valve on the side wall of the return oil pipe 34, and the first spring 73 extends to push the hydraulic oil through the return oil pipe 34 back into the oil tank 31, causing the fixing plate 72 to retract.

[0019] A flange mechanism 6 is installed at one end of the support platform 1; the flange mechanism 6 includes a guide rail 61, and guide rails 51 are symmetrically installed on the surface of the support platform 1. The guide rails 61 are slidably connected to the mounting plate 62; the side wall of the mounting plate 62 is provided with a groove 64, and a connecting plate 63 is slidably connected inside the groove 64; one end of the connecting plate 63 is rotatably connected to a second support rod 611, and one end of the second support rod 611 is rotatably connected to a lower roller 65; a first support rod 610 is slidably connected inside the mounting plate 62, and one end of the first support rod 610 is rotatably connected to an upper roller 67; the side wall of the upper roller 67 is symmetrically threaded to a fixed sleeve 69, and multiple balls 68 are rollingly connected to the side wall of the fixed sleeve 69. The ball bearing 68 abuts against the top of the cylinder 5; the side wall of the flanging mechanism 6 is equipped with an extrusion mechanism 8, the extrusion mechanism 8 includes a fourth connecting rod 85, the side wall of the fourth connecting rod 85 is fixedly connected to the first support rod 610, the interior of the fourth connecting rod 85 is slidably connected to a third connecting rod 84, and the third connecting rod 84 abuts against the side wall of the second support rod 611; the side wall of the third connecting rod 84 is vertically fixedly connected to a second connecting rod 83, the interior of the second connecting rod 83 is slidably connected to a first connecting rod 82; a second spring 86 is installed inside both the second connecting rod 83 and the fourth connecting rod 85, and one end of the first connecting rod 82 and the third connecting rod 84 is connected to the second spring 86. Spring 86; The side wall of the first connecting rod 82 is fixedly connected to an arc-shaped extrusion ring 81, and the extrusion ring 81 abuts against the side wall of the cylinder 5; When the lower roller 65 is used to flanging the cylinder 5, the upper roller 67 abuts against the top surface of the cylinder 5, and the cylinder 5 is located between the two fixed sleeves 69. The side wall of the upper roller 67 rotates to the fixed sleeves 69, so that the fixed sleeves 69 are close to each other, and the ball 68 abuts against the side wall of the cylinder 5. When the lower roller 65 presses the cylinder 5 upward to flanging, the upper roller 67 presses the cylinder 5 downward. The lower roller 65 and the upper roller 67 are aligned, forming a closed force loop, which avoids uneven force on the surface of the cylinder 5. Meanwhile, both ends of the cylinder 5 abut against a fixed sleeve 69, symmetrically limiting the cylinder 5 and increasing the stability of the cylinder 5 during rotation; when the lower roller 65 presses the cylinder 5 upward, the second spring 86 inside the third connecting rod 84 extends and pushes the extrusion ring 81 against the side wall of the cylinder 5. During the movement of the lower roller 65, the second spring 86 inside the first connecting rod 82 extends and retracts, changing the height of the second connecting rod 83 and the extrusion ring 81, thereby ensuring that the distance between the extrusion ring 81 and the second support rod 611 remains unchanged. The contact point between the extrusion ring 81 and the cylinder 5 is located directly above the flange position, and the distance between the two is small.The lower roller 65 presses the cylinder 5 from the inside out, and the extrusion ring 81 presses the cylinder 5 from the outside in, thereby protecting the side wall of the cylinder 5 above the flange position. The arc-shaped side wall of the extrusion ring 81 increases the contact area with the cylinder, thereby reducing the occurrence rate of flange wrinkles on the cylinder 5.

[0020] The rotating mechanism 2 includes a motor 22. The motor 22, which drives the first gear 21 to rotate, is installed inside the support platform 1. A base 25 is installed inside the support platform 1, and a support column 23 is rotatably connected inside the base 25. A second gear 24 is fixedly connected to the side wall of the support column 23. The second gear 24 meshes with the first gear 21. In order to drive the motor 22, the motor 22 drives the first gear 21 and the second gear 24 to rotate. The diameter of the first gear 21 is larger than the diameter of the second gear 24. In order to increase the rotational speed of the second gear 24 and the support column 23, the support column 23 drives the clamp 7 and the cylinder 5 to rotate, which facilitates the flanging of the cylinder 5.

[0021] Both the oil outlet pipe 33 and the oil return pipe 34 are connected to the hydraulic rod 35, which consists of a cylinder and a piston rod. Cylinders are installed on the surface of the support platform 1, the interior of the support platform 1, the surface of the mounting plate 62, and the side wall of the connecting plate 63. One end of multiple piston rods is connected to the mounting plate 62, the fixing rod 4, and the fourth connecting rod 85, respectively, with the fixing rod 4 arranged in a ring around the clamp 7. To facilitate the operation of the hydraulic pump 32, hydraulic oil from the oil tank 31 is input into the cylinder. By controlling the direction of the hydraulic oil entering the cylinder, the piston rod extends and retracts within the cylinder, causing the hydraulic rod 25 to move and push the mounting plate 62, the fixing rod 4, and the fourth connecting rod 85.

[0022] The mounting plate 62 has a surface-mounted support 66, and the piston rod corresponding to the connecting plate 63 is rotatably connected to the support 66. The mounting plate 62 has an interior clamping plate 612 with arc-shaped sidewalls. The sidewall of the clamping plate 612 has an arc-shaped groove 613. A second support rod 611, with one end spherical, is slidably connected to the interior of the groove 613. The center of the groove 613 and the center of the slide groove 64 are on the same straight line. When the hydraulic rod 35 on the sidewall of the connecting plate 63 operates, one end of the hydraulic rod 35 rotates inside the support 66, simultaneously pulling the connecting plate 63 and the second support rod 611 along the slide groove 64. The spherical end of the second support rod 611 moves upward along the groove 613. During this upward movement of the second support rod 611 along the slide groove 64 and the groove 613, rotation of the second support rod 611 is prevented, facilitating the lower roller 65 to press against the surface of the cylinder 5.

[0023] The working principle of the thin-walled circular container flange device provided by this utility model is as follows: The device is connected to an external power source. First, the cylinder 5 is placed on the surface of the fixing rod 4, and the clamp 7 is located inside the cylinder 5. The hydraulic pump 32 operates, and the side valve of the oil outlet pipe 33 is opened. The hydraulic pump 32 pumps hydraulic oil from the oil tank 31 through the oil outlet pipe 33 and the support column 23 into the interior of the slide cylinder 75, pushing the piston 74 and the slide rod 76 to move inside the slide cylinder 75 and compress the first spring 73. The slide rod 76 pushes the fixing plate 72 outward, causing the fixing plate 72 to adhere tightly to the inner side wall of the cylinder 5, thus fixing the cylinder 5. The hydraulic rod 35 connected to the fixing rod 4 is opened, and the hydraulic rod 35 retracts, causing the fixing rod 4 to move downward, separating the fixing rod 4 from the cylinder 5. The hydraulic rod 35 on the surface of the support platform 1 is opened, pushing the mounting plate 62 to move along the guide rail 61, causing the upper roller 67 to reach the appropriate position. Open the hydraulic rod 35 corresponding to the upper roller 67, pushing the upper roller 67 downward so that it abuts against the top surface of the cylinder 5. The upper roller 67 rotates to the fixing sleeve 69 on its side wall, bringing the fixing sleeves 69 closer together, causing the ball bearings 68 to abut against the side wall of the cylinder 5. The distance between the two fixing sleeves 69 is adjustable, facilitating the flanged cylinder 5. Turn on the motor 22, causing the support column 23, the clamp 7, and the cylinder 5 to rotate. The cylinder 5 rotates to push out the ball bearings 68, the fixing sleeves 69, and the upper roller 65. The rolling of the ball bearings 68 reduces the resistance during the rotation of the cylinder 5, while also facilitating the upper roller 65 and the fixing sleeves 69 to fix the cylinder 5. When the hydraulic rod 35 on the side wall of the connecting plate 63 is opened, one end of the hydraulic rod 35 rotates inside the support 66, simultaneously pulling the connecting plate 63 and the second support rod 611 along the slide groove 64. The spherical end of the second support rod 611 moves upward along the slot 613, preventing the second support rod 611 from rotating during its upward movement along the slide groove 64 and the slot 613. The lower roller 65 moves upward in an arc shape, pressing the surface of the cylinder 5, preventing excessive pressure from the lower roller 65 on the cylinder 5, and simultaneously slowing down the upward speed of the lower roller 65 to prevent rapid deformation of the cylinder 5 from affecting the flanging quality.When the cylinder 5 rotates, it pushes the lower roller 65 to rotate on the side wall of the second support rod 611, and the upper roller 67 rotates on the side wall of the first support rod 610 and presses the cylinder 5 downward. The lower roller 65 and the upper roller 67 are aligned to form a closed force loop, avoiding uneven force on the surface of the cylinder 5. At the same time, both ends of the cylinder 5 abut against a fixed sleeve 69, symmetrically limiting the cylinder 5 and increasing the stability of the cylinder 5 during rotation. When the lower roller 65 presses the cylinder 5 upward, the second spring 86 inside the third connecting rod 84 extends and pushes the extrusion ring 81 against the side wall of the cylinder 5. During the movement of the lower roller 65... The second spring 86 inside the first connecting rod 82 extends and retracts, changing the height of the second connecting rod 83 and the extrusion ring 81, thereby ensuring that the distance between the extrusion ring 81 and the second support rod 611 remains unchanged. The contact point between the extrusion ring 81 and the cylinder 5 is located directly above the flange position, and the distance between the two is small. The side wall of the cylinder 5 is thin. During flange formation, the lower roller 65 extrudes the cylinder 5 from the inside out, and the extrusion ring 81 extrudes the cylinder 5 from the outside in, thereby protecting the side wall of the cylinder 5 above the flange position. The arc-shaped side wall of the extrusion ring 81 increases the contact area with the cylinder, thereby reducing the occurrence rate of flange wrinkles on the cylinder 5.
