[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0024] Please see Figures 1-4 A stainless steel pipe bending device includes a servo motor 100 and a linear motor 200. The top of the servo motor 100 is connected to a rotating disk 300, and the top of the rotating disk 300 is fixedly connected to an arc-shaped guide rail 400 and an auxiliary guide rail 500. The side of the linear motor 200 is connected to a vertical guide rail 600.

[0025] The auxiliary guide rail 500 is internally equipped with a clamping assembly 700, which includes a pneumatic chamber 701 and a hydraulic chamber 702. One end of the pneumatic chamber 701 is fixedly connected to an elastic airbag 703. A hollow tube is inserted into the auxiliary guide rail 500 from one side of the vertical guide rail 600. When the hollow tube compresses the elastic airbag 703 on the vertical guide rail 600, the gas inside the elastic airbag 703 is forced into the pneumatic chamber 701, which is fixedly connected to it, thereby increasing the pressure inside the pneumatic chamber 701. A locking rod 704 is slidably connected to the other end of the air pressure chamber 701. A power rod 705 is slidably connected to the side of the hydraulic chamber 702. A slot 706 is provided on the side of the power rod 705, located outside the locking rod 704, and the cross-sectional shape of the slot 706 matches the cross-sectional shape of the locking rod 704. A spring 707 is fixedly connected to the side of the power rod 705. The end of the spring 707 away from the power rod 705 is located inside the hydraulic chamber 702 and fixedly connected to the inner wall of the hydraulic chamber 702. When the pressure inside the air pressure chamber 701 increases, it moves the locking rod 704 slidably connected to the air pressure chamber 701. The locking rod 704 then moves out of the slot 706 on the power rod 705, thus freeing the slot 706 from its restraint. Under the action of the spring 707 fixedly connected to it, the locking rod moves towards the hydraulic chamber 702, increasing the pressure inside the hydraulic chamber 702 slidably connected to the power rod 705. A support plate 708 is slidably connected to the outer side of the hydraulic chamber 702. When the pressure inside the hydraulic chamber 702 increases, it causes the support plate 708, which is slidably connected to the hydraulic chamber 702, to move. The support plate 708 moves towards the inner wall of the hollow pipe and provides support, cooperating with the auxiliary guide rail 500 and the arc-shaped guide rail 400 for clamping. Then, the servo motor 100 and the linear motor 200 are started, which drives the arc-shaped guide rail 400 and the auxiliary guide rail 500 to rotate slowly, while the vertical guide rail 600 moves slowly, performing a bending operation on the hollow pipe. This reduces the possibility of damage to the pipe caused by clamping.

[0026] In use, a hollow tube is inserted into the auxiliary guide rail 500 from one side of the vertical guide rail 600. When the hollow tube compresses the elastic airbag 703 on the vertical guide rail 600, the gas inside the elastic airbag 703 is forced into the pressure chamber 701 fixedly connected to it, increasing the pressure inside the pressure chamber 701. This causes the locking rod 704, which is slidably connected to the pressure chamber 701, to move. The locking rod 704 then moves out of the slot 706 on the power rod 705, thus removing the restriction from the slot 706. Under the action of the spring 707 fixedly connected to it... The device moves towards the hydraulic chamber 702, increasing the pressure inside the hydraulic chamber 702 which is slidably connected to the power rod 705. This causes the support plate 708, which is slidably connected to the hydraulic chamber 702, to move. The support plate 708 moves towards the inner wall of the hollow pipe and provides support, working in conjunction with the auxiliary guide rail 500 and the arc-shaped guide rail 400 for clamping. Then, the servo motor 100 and the linear motor 200 are started, which drives the arc-shaped guide rail 400 and the auxiliary guide rail 500 to rotate slowly, while the vertical guide rail 600 moves slowly, performing a bending operation on the hollow pipe. Example

[0027] Please see Figures 1-4 Based on Embodiment 1, a reset assembly 800 is provided on the side of the auxiliary guide rail 500. The reset assembly 800 includes a second hydraulic chamber 801, which is located on the side of the first hydraulic chamber 702 and is fixedly connected and communicates with the first hydraulic chamber 702. A pull rod 802 is fixedly connected to the side of the second hydraulic chamber 801. After the bending operation is completed, by pulling the pull rod 802, the pull rod 802 moves away from the second hydraulic chamber 801, which, in conjunction with the second hydraulic chamber 801 which is slidably connected to the pull rod 802, reduces the pressure inside the second hydraulic chamber 801. A baffle 803 is rotatably connected to the inner wall of the second hydraulic chamber 801. Two springs 804 are fixedly connected to the side of the baffle 803, and the two springs 804 are symmetrically distributed about the baffle 803. When the pressure inside hydraulic chamber 2 801 decreases, because a baffle 803 is rotatably connected inside hydraulic chamber 2 801, and both sides of the baffle 803 are connected to the inner wall of hydraulic chamber 2 801 through spring 2 804, the baffle 803 squeezes the spring 2 804 near the pull rod 802 to rotate. Hydraulic chamber 2 801 at the pull rod 802 then connects to hydraulic chamber 1 702 through the baffle 803. Continuing to pull the pull rod 802 causes the pressure inside hydraulic chamber 1 702 to decrease synchronously. The support plate 708, which is slidably connected to hydraulic chamber 1 702, then resets, canceling the support for the hollow pipe. The bent hollow pipe can then be removed for subsequent use of the device.

[0028] In use, based on Embodiment 1, after the bending operation is completed, by pulling the pull rod 802, the pull rod 802 moves away from the hydraulic chamber 2 801. In conjunction with the hydraulic chamber 2 801 which is slidably connected to the pull rod 802, the pressure inside the hydraulic chamber 2 801 decreases. Since the baffle 803 is rotatably connected inside the hydraulic chamber 2 801, and both sides of the baffle 803 are connected to the inner wall of the hydraulic chamber 2 801 through the spring 2 804, the baffle 803 squeezes the spring 2 804 on the side near the pull rod 802 to rotate. The hydraulic chamber 2 801 at the pull rod 802 then connects to the hydraulic chamber 1 702 through the baffle 803. Continuing to pull the pull rod 802, the pressure inside the hydraulic chamber 1 702 decreases synchronously. The support plate 708 which is slidably connected to the hydraulic chamber 1 702 then resets, canceling the support for the hollow pipe. The hollow pipe after bending can then be removed.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
