[0017] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.
[0018] Reference Figure 1-3 The bottom of the workbench 1 is fixedly installed with a telescopic cylinder 6, and the output end of the telescopic cylinder 6 is fixedly connected to the bottom of the connecting shaft 4. The connecting shaft 4 is controlled by the telescopic cylinder 6 to move in the slide groove 3, thereby adjusting the height of the positioning cylinder 5. The rear end of the connecting shaft 4 is rotatably connected to the front end of the connecting shaft 4, and the rear end of the connecting shaft 4 extends out of the rear end of the slide groove 3 and is fixedly connected to the limiting ring 16. The limiting ring 16 abuts against the rear end of the supporting column 2, and provides limitation and support when the positioning cylinder 5 is under pressure, thereby improving the stability of the connecting shaft 4. The bottom of the workbench 1 is fixedly installed with a telescopic cylinder 6, and the output end of the telescopic cylinder 6 is fixedly connected to the bottom of the connecting shaft 4. The connecting shaft 4 is controlled to move in the slide groove 3 by the telescopic cylinder 6, and then the height of the positioning cylinder 5 is adjusted. The rear end of the supporting column 2 is fixedly installed with a motor 7, and the output end of the motor 7 passes through the supporting column 2 and is fixedly connected to the rear end of the bending cylinder 8. While taking the bending cylinder 8 as the bending point, the bending cylinder 8 is controlled to rotate by the motor 7, thereby pushing the tube sheet 14 to move, so as to avoid the tube sheet 14 being damaged due to bending. A hydraulic cylinder 9 is fixedly installed on the top, and the output end of the hydraulic cylinder 9 passes through the top of the support 2 and is fixedly connected to the surface of the rotating drum 10. The rotating drum 10 is rotatably installed on the left end of the bracket 11 through the fixed rod 12. The rotating drum 10 is sleeved on the surface of the fixed rod 12. The fixed rod 12 is fixedly connected to the left end of the bracket 11. The rotating drum 10 is stretched by the hydraulic cylinder 9, and then the left end of the bracket 11 is stretched. The inner wall size of the rotating drum 10 is larger than the size of the fixed rod 12 to avoid motion interference during the stretching process. The right end of the bracket 11 is rotatably mounted on the left side of the lower end of the support 2 through a fixing rod 12, and a bending wheel 13 is rotatably mounted on the front end of the bracket 11. The movement of the bracket 11 is controlled by a hydraulic cylinder 9, and then the movement of the bending wheel 13 is controlled to bend the sheet material. A positioning plate 15 is fixedly mounted on the left end of the workbench 1, and a tube sheet 14 is placed between the positioning cylinder 5 and the bending cylinder 8. The left end of the tube sheet 14 is abutted against the right end of the positioning plate 15. The positioning plate 15 positions one end of the tube sheet 14, so that the bending accuracy of the tube sheet 14 is higher.
[0019] In another embodiment provided by the present utility model, Figure 1 As shown, the size of the slide groove 3 matches the size of the connecting shaft 4, and the connecting shaft 4 moves inside the slide groove 3. The matching sizes make the movement more stable.

[0021] In another embodiment provided by the present utility model, Figure 1 As shown, the output end of the telescopic cylinder 6 passes through the workbench 1 and extends into the interior of the slide groove 3 and is fixedly connected to the lower end of the connecting shaft 4. The telescopic cylinder 6 controls the directional movement of the connecting shaft 4 in the slide groove 3 to adjust the relative heights of the positioning cylinder 5 and the bending cylinder 8, thereby adapting to tubular sheets of different specifications.
[0022] Working principle: In the utility model, the tube sheet 14 is placed between the positioning cylinder 5 and the bending cylinder 8, and the connecting shaft 4 is controlled to move in the slide groove 3 by the telescopic cylinder 6, so as to adjust the height of the positioning cylinder 5, so that the upper and lower ends of the tube sheet 14 are respectively abutted against the bottom of the bending cylinder 8 and the top of the positioning cylinder 5, and then the left end of the tube sheet 14 is abutted against the positioning plate 15 for positioning, and the rotating cylinder 10 is controlled by the hydraulic cylinder 9 to drive the left end of the bracket 11 to move upward, and then the bending wheel 13 is controlled to move upward, so as to bend the tube sheet 14, and at the same time, the bending cylinder 8 is controlled to rotate by the motor 7, so as to push the tube sheet 14 to move.
