After the tube body is fixed, the tube bending operation can be performed. One end of the connecting seat 5 is rotatably connected to the central axis of the first tube bending disk 6, and the other end is rotatably connected to the mounting frame 24. As a result, the mounting frame 24 can be stretched and then rolled on the surface of the tube body. After the tube bending is completed, the mounting frame 24 is removed from the upper surface of the tube body, and the movable tube body can be taken out from between the first tube bending disk 6 and the bracket 13.
[0027] The handle 8 is provided with a bending component on the outside, and the rotating telescopic fixing piece can be flexibly installed in conjunction with the workbench.
[0028] The rotating telescopic fixing member includes a storage groove 30 provided inside one end of the base 3, the storage groove 30 is connected with a screw rod 11 through a rotating shaft 7 arranged to rotate, the screw rod 11 is externally threadedly connected with a threaded seat 16, and a movable component is arranged outside the threaded seat 16;
[0029] like Figure 1 and Figure 2 As shown, a rotating shaft 7 is provided inside the storage groove 30, so that the screw rod 11 can rotate flexibly. When installed on one side of a workbench for use, the position of the threaded seat 16 is adjusted according to the width of the workbench surface, and then fixed to the workbench, so that the handle 8 can be pressed against the short pipe, which saves effort when bending the pipe.
[0030] The movable assembly includes a swivel 20 rotatably sleeved on the outside of the threaded seat 16, a stopper 21 is fixedly arranged on the outside of the swivel 20, and the inside of the stopper 21, at one end away from the swivel 20, is connected to the second bending tube disc 12 through a rotating member;
[0031] like Figure 3 and Figure 5 As shown, the swivel 20 can enable the second pipe bending disc 12 to rotate to different directions as needed when the threaded seat 16 rotates.
[0032] The rotating member includes a cylinder 26 fixedly inserted in the end of the stop rod 21 away from the rotating ring 20, a rotating rod 29 is rotatably installed inside the cylinder 26, and a connecting block 23 is fixedly arranged at the end of the rotating rod 29 away from the cylinder 26, and one side of the connecting block 23 is connected to the second bending tube disc 12;
[0033] like Figure 2 , Figure 3 and Figure 5 As shown, in order to improve the stability during bending, the screw rod 11 at one end of the base 3 can be rotatably installed on one side of the workbench, so that the second bending tube disk 12 can be rotated together with the rotating rod 29 and the cylinder 26 so that the surface of the second bending tube disk 12 is in contact with the bottom of the workbench.
[0034] The bending resistance assembly includes a mounting sleeve 9 which is sleeved on the outside of the handle 8. A fixed shaft 15 is fixedly provided on one side of the mounting sleeve 9. Ring sleeves 17 are rotatably connected to the outside of the fixed shaft 15. A sleeve shell 10 is fixedly provided on the outside of the ring sleeve 17. A pressing mechanism is provided inside the sleeve shell 10.
[0035] The pressing mechanism includes a cylinder 31 fixedly embedded in the sleeve 10, a clamping seat 19 is fixedly provided at the telescopic end of the cylinder 31, a movable rod 14 is rotatably installed inside the end of the clamping seat 19 away from the cylinder 31, a first pipe bending wheel 18 is rotatably installed inside the movable rod 14, and the ends of the two sets of movable rods 14 away from the first pipe bending wheel 18 are connected by a rotatably arranged clamping shaft, and a pad 4 is provided at the bottom of the end of the base 3 away from the storage groove 30;
[0036] like Figure 1 , Figure 2 and Figure 3 As shown, the two sets of movable rods 14 are rotated together on one side close to each other through a set clamping shaft. When the cylinder 31 presses the first tube bending wheel 18 to adhere to the upper surface of one side of the long tube, the long tube can be pressed down in correspondence with the first tube bending wheel 18, thereby providing convenience when the middle section of the long tube is bent at a small angle.
[0037] A card housing 25 is fixedly arranged below the outside of the threaded seat 16, and a pull rod 22 is rotatably installed inside the card housing 25;
[0038] like Figure 3 , Figure 4 and Figure 5 As shown, the pull rod 22 inside the housing 25 can be easily rotated by a worker, so that the threaded seat 16 can rotate outside the screw rod 11.
[0039] Working principle: When bending a short tube of fixed length, first place the bottom of the base 3 on one side of the table top of the workbench, rotate the screw 11 to be vertical, and then rotate the pull rod 22 to cause the threaded seat 16 to move upward, so that the second tube bending disk 12 can be pressed against the bottom of the workbench in a flat surface, so as to fix the tube bender, thereby enhancing the stability of the handle 8 during bending. Then open the handle 8 and the mounting frame 24 to one end, insert one end of the short tube from the channel between the first tube bending disk 6 and the bracket 13, and one end of the short tube is pressed against the lower edge of the bracket 13. Then the worker presses the handle 8 downward, and the outer surface of the other side of the short tube is pressed against the inside of the first tube bending disk 6. According to the required angle of the tube bending, with the rotation cooperation of the connecting seat 5, the second tube bending wheel 27 inside the mounting frame 24 can be at the short tube. The upper surface rolls, and the pressure fulcrum is changed during the rolling process, so as to achieve the need for bending the pipe at a precise angle. When bending a longer pipe body, the screw rod 11 is rotated to the other end of the base 3, so that the screw rod 11 contacts the workbench surface, and the pressure rod 21 is rotated to be vertically set to the workbench, and the second pipe bending disk 12 is rotated to make the groove inside the second pipe bending handle 8 consistent with the rolling cut surface of the first pipe bending wheel 18 outside the handle 8. The long tube body is directly placed in the internal groove of the second pipe bending disk 12, and then the cylinder 31 inside the shell 10 is driven accordingly. Under the connection of the card shaft, the two sets of movable rods 14 and the first pipe bending wheel 18 are pressed against the two ends of the long tube. Under the support of the second pipe bending disk 12, the two ends of the long tube body are bent downward. This method can be quickly operated when performing a simple bend in the middle of the long tube body.
