Description

Technical Field

[0001] The utility model relates to the technical field of pipe bending devices, in particular to a pipe bending device for metal pipes with special-shaped cross-sections. Background Art

[0002] Metal pipe is a material widely used in various industrial and construction fields. According to different materials, metal pipes can be divided into iron pipes, steel pipes, stainless steel pipes, copper pipes, aluminum pipes, titanium pipes, etc. Each type of metal pipe has its own unique physical and chemical properties and is suitable for different working environments and application scenarios. Among them, special-section metal pipes refer to metal pipes with non-conventional circular cross-sectional shapes. They can have a variety of different cross-sectional shapes. Compared with round pipes, special-shaped pipes generally have a larger moment of inertia and section modulus, and can provide greater bending and torsional resistance. In the production process of special-section metal pipes, pipe bending devices are generally used to produce the pipes into the required shape.

[0003] Existing pipe bending devices generally fix the pipe by fixing components first, and then bend the pipe by a power device such as a telescopic cylinder or an electric motor to shape the pipe. However, during the pipe bending process, the existing pipe bending devices generally fix the bending diameter of the pipe and cannot adjust the bending diameter of the pipe. When the bending diameter needs to be changed, multiple different devices need to be used, which is cumbersome to use. In order to solve this technical problem, the utility model proposes a pipe bending device for metal pipes with special-shaped cross-sections. Utility Model Content

The outer surface of the first sliding rod 503 is slidably connected to the adjustment mechanism 5. The second telescopic rod 502 can drive the fixed plate 3 to slide on the fixed shell 2, thereby adjusting the position of the special-shaped tube so that the special-shaped tube is close to the bending plate 12. The first sliding rod 503 is used to increase the stability of the fixed plate 3 when sliding to prevent it from tilting or offsetting.

[0025] The upper part of the base 1 is slidably connected to a rotating plate 6, and a power mechanism 7 is provided on the outside of the rotating plate 6. The power mechanism 7 includes a second motor 701. The outer surface of the second motor 701 is fixedly connected to the fixed shell 2. The output end of the second motor 701 is connected to a gear 702. The outer surface of the gear 702 is meshed with a gear ring 703. The lower surface of the gear ring 703 is fixedly connected to the rotating plate 6. The gear 702 can be driven to rotate by the second motor 701. The gear 702 cooperates with the gear ring 703 to drive the rotating plate 6 to rotate around the center of the gear ring 703.

A sliding groove is provided on the base 1 to facilitate the sliding of the second limiting block 802 therein. The rotating plate 6 is limited by the first limiting block 801 and the second limiting block 802 to prevent the rotating plate 6 from deflecting during rotation and increase its stability.

[0027] An extrusion mechanism 9 is provided on the upper part of the rotating plate 6, and the extrusion mechanism 9 includes a third telescopic rod 901. The outer surface of the third telescopic rod 901 is installed on the rotating plate 6. The telescopic end of the third telescopic rod 901 is fixedly connected to the extrusion plate 10. A second sliding rod 902 is fixedly connected to one side of the extrusion plate 10. The outer surface of the second sliding rod 902 is slidably connected to the rotating plate 6.

[0028] An extrusion plate 10 is provided at one end of the extrusion mechanism 9, and a first telescopic rod 11 is installed on the upper surface of the rotating plate 6. A plurality of bending plates 12 of different sizes are installed on the upper end of the first telescopic rod 11. The lower surface of the bending plate 12 is fixedly connected with a telescopic sleeve 13. The lower end of the telescopic sleeve 13 is fixedly connected to the rotating plate 6. The first telescopic rod 11 can drive the bending plate 12 to move upward or downward, and at the same time drive the telescopic sleeve 13 to shorten or extend. The telescopic sleeve 13 is composed of two sleeves of different thicknesses put together. The telescopic sleeve 13 is used to increase the stability of the bending plate 12 to prevent it from tilting or offset.

[0029] When in use, the special-shaped tube that needs to be bent passes through the inside of the fixed plate 3, and the special-shaped tube can be transported by the conveying mechanism 4 for easy use. The rotating plate 6 can be driven to rotate by the power mechanism 7, and the extrusion mechanism 9 can drive the extrusion plate 10 to squeeze and fix the special-shaped tube on one side of the bending plate 12. As the bending plate 12 and the extrusion plate 10 rotate, the special-shaped tube can be bent. There are multiple bending plates 12 with different sizes, which are fixed and stacked together in sequence.

[0030] It should be noted that, in actual use of the device, the special-shaped tube is first inserted into the interior of the fixed plate 3, and the special-shaped tube is transported by the conveying mechanism 4 so that the special-shaped tube passes between the bending plate 12 and the extrusion plate 10. The position of the special-shaped tube is adjusted by the adjusting mechanism 5 so that the special-shaped tube squeezes the bending plate 12, and then the extrusion plate 10 is driven by the extrusion mechanism 9 to squeeze the special-shaped tube, so that it is fixed between the bending plate 12 and the extrusion plate 10. The power mechanism 7 drives the rotating plate 6 to rotate, and the rotating plate 6 drives the bending plate 12 and the extrusion plate 10 to rotate, thereby bending the special-shaped tube so that it moves with the bending plate 12, thereby achieving the purpose of bending the special-shaped tube.

[0031] When the bending diameter of the special-shaped pipe needs to be adjusted, there is no need to remove the pipe. The extrusion mechanism 9 drives the extrusion plate 10 to move away from the pipe, and the adjustment mechanism 5 drives the pipe to move away from the bending plate 12, so that the pipe is not in contact with the bending plate 12 and the extrusion plate 10. Then the first telescopic rod 11 drives the bending plate 12 to move downward, so that the smaller bending plate 12 moves to the pipe, and then the pipe is squeezed. By using bending plates 12 of different sizes, the special-shaped pipe can be bent into different bending diameters, thereby achieving the effect of adjusting the bending diameter of the pipe.

[0032] The first motor 401, the second motor 701, the first telescopic rod 11, the second telescopic rod 502 and the third telescopic rod 901 in this application are all common electrical equipment in the prior art. This application will not go into too much detail about their models or internal structures, and they can also be replaced by other power sources.
