[0029] Reference Figure 1-4 As shown, the limit device 2 includes a fixed plate 21, which is fixedly connected to the upper surface of the workbench 1, and a moving rod 22 is slidably penetrated through the surface of the fixed plate 21, one end of the moving rod 22 is fixedly connected to a limit plate 23, one side of the limit plate 23 is fixedly connected to a pointer 24, a scale 25 is fixedly connected to the workbench 1 corresponding to the pointer 24, and a pad 26 is fixedly connected to one side of the fixed plate 21, and a bolt 27 is threadedly inserted into the surface of the pad 26. Before the pipe needs to be bent, the staff first pulls the moving rod 22, and the moving rod 22 moves with the limit plate 23. The staff judges the position of the limit plate 23 by the position of the scale 25 pointed to by the pointer 24 on one side of the limit plate 23. When the limit plate 23 moves to the appropriate position, the staff rotates the bolt 27 on the pad 26, and the bolt 27 squeezes the moving rod 22, thereby fixing the moving rod 22 and the limit plate 23. Finally, the staff puts one end of the pipe against the limit plate 23, and the part of the pipe that needs to be bent is just at the circular plate 4. At this time, the cylinder 5 is opened, and the cylinder 5 brings the clamping plate 6 and the circular plate 4 to limit the pipe. The driving device 7 is turned on, and the driving device 7 rotates with the rotating member 8 through the belt, and the rotating member 8 bends the pipe with the help of the circular plate 4. The limiting device 2 is used to facilitate the staff to determine the part of the pipe that needs to be bent, thereby improving the accuracy of the pipe bending and bringing convenience to the staff.
[0030] Reference Figure 1-4As shown, one end of the mobile rod 22 is fixedly connected with a pull plate 211, and the surface of the pull plate 211 is provided with anti-slip grooves. By setting the pull plate 211, the effect of facilitating the staff to move the mobile rod 22 is achieved, which brings inconvenience to the staff. The surface of the mobile rod 22 is fixedly connected with a plurality of rubber strips 29, and the plurality of rubber strips 29 are linearly distributed. By setting the rubber strips 29, the friction between the bolt 27 and the mobile rod 22 is increased, which brings convenience to the staff to fix the mobile rod 22. The surface of the fixed plate 21 is provided with a limit rod 210, and one end of the limit rod 210 is fixedly connected to the limit plate 23. By setting the limit rod 210, the effect of limiting the moving direction of the limit plate 23 is achieved, the limit plate 23 is prevented from rotating, and the stability of the movement of the limit plate 23 is improved. A pull rope 28 is fixedly connected to one side of the bolt 27, and one end of the pull rope 28 is fixedly connected to the pad 26. By setting the pull rope 28, the effect of limiting the maximum displacement of the bolt 27 is achieved, and the bolt 27 is prevented from falling when not in use.

A threaded barrel 32 is fixedly connected to the side of the first rectangular plate 31 close to the second rectangular plate 34, and a screw 33 is connected to the inner thread of the threaded barrel 32. When it is necessary to fix pipes of different sizes, the staff first rotates the screw 33, and the screw 33 rotates in the threaded barrel 32, and the total length of the screw 33 and the threaded barrel 32 changes. When the total length of the screw 33 and the threaded barrel 32 is adjusted to a suitable length, when the cylinder 5 clamps the pipe with the clamping plate 6, the second rectangular plate 34 moves to one end of the screw 33, achieving the effect of limiting the maximum displacement of the clamping plate 6 and the second rectangular plate 34. The auxiliary device 3 achieves the effect of limiting the maximum displacement of the clamping plate 6, and avoids the cylinder 5 clamping the pipe with the clamping plate 6.
[0032] Reference Figure 1-4 As shown, a handle 35 is fixedly connected to one end of the screw rod 33, and the surface of the handle 35 is provided with anti-slip grooves. The handle 35 is provided to facilitate the staff to rotate the screw rod 33, which brings convenience to the staff. A rubber pad 36 is fixedly connected to the side of the second rectangular plate 34 close to the screw rod 33, and the size of the rubber pad 36 is adapted to the size of the handle 35. The rubber pad 36 is provided to protect the handle 35, so as to prevent the handle 35 from contacting with the second rectangular plate 34 and causing damage.
[0033] Working principle: before the pipe needs to be bent, the staff first pulls the moving rod 22 through the pull plate 211, and the moving rod 22 moves with the limit plate 23. The staff judges the position of the limit plate 23 by the position of the scale 25 pointed to by the pointer 24 on one side of the limit plate 23. After the limit plate 23 moves to the appropriate position, the staff rotates the bolt 27 on the pad 26, and the bolt 27 squeezes the rubber strip 29 on the moving rod 22, thereby achieving the effect of fixing the moving rod 22 and the limit plate 23. Finally, the staff puts one end of the pipe against the limit plate 23, and the part of the pipe that needs to be bent is exactly at the circular plate 4. At this time, the cylinder 5 is opened, and the cylinder 5 limits the pipe with the clamping plate 6 and the circular plate 4. The driving device 7 is turned on, and the driving device 7 rotates with the rotating member 8 through the belt, and the rotating member 8 bends the pipe with the help of the circular plate 4. The limiting device 2 is used to facilitate the staff to determine the part of the pipe that needs to be bent, thereby improving the accuracy of the pipe bending and bringing convenience to the staff.
[0034] When it is necessary to fix pipes of different sizes, the staff first rotates the screw 33 through the handle 35, and the screw 33 rotates in the threaded barrel 32, and the total length of the screw 33 and the threaded barrel 32 changes. When the total length of the screw 33 and the threaded barrel 32 is adjusted to an appropriate length, the cylinder 5 clamps the pipe with the clamp 6, and the second rectangular plate 34 moves to one end of the screw 33, and the rubber pad 36 on the second rectangular plate 34 fits with the handle 35, thereby achieving the effect of limiting the maximum displacement of the clamp 6 and the second rectangular plate 34. The auxiliary device 3 achieves the effect of limiting the maximum displacement of the clamp 6, thereby preventing the cylinder 5 from clamping the pipe with the clamp 6.
