In industrial production, there is a stable practical demand for bending processing of flue gas ducts, aiming to achieve precise duct forming through appropriate processing equipment, ensuring their installation compatibility and performance within the system.

[0003] In the existing technology, the sidewalls of flue gas ducts are not cleaned during the bending process, which makes it easy for impurities to remain on the sidewalls. These impurities can cause scratches and wear on the surface of the ducts during the bending operation, which affects the bending quality of the flue gas ducts to a certain extent. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flue gas duct bending and forming machine, comprising a table, a motor fixedly connected to the lower surface of the table, the output end of the motor rotatably connected to the inside of the table and fixedly connected to a rotating disk, the outer wall of the rotating disk rotatably connected to the inside of the table, a main bending roller rotatably connected to the top of the rotating disk, an auxiliary bending roller rotatably connected to the top of the rotating disk, a U-shaped frame fixedly connected to the upper surface of the table, and a cleaning component provided on the upper surface of the table.

[0026] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Example 1

[0028] Reference Figure 1 - Figure 7An embodiment of this utility model provides a flue gas duct bending and forming machine, including a table 1, a motor 2 fixedly connected to the lower surface of the table 1, the output end of the motor 2 rotatably connected to the inside of the table 1 and fixedly connected to a rotating disk 3, the outer wall of the rotating disk 3 rotatably connected to the inside of the table 1, a main bending roller 4 rotatably connected to the top of the rotating disk 3, an auxiliary bending roller 5 rotatably connected to the top of the rotating disk 3, a U-shaped frame 6 fixedly connected to the upper surface of the table 1, and a cleaning component provided on the upper surface of the table 1.

[0029] Specifically, when in use, motor 2 is started, and the output end of motor 2 drives the rotating disk 3 to rotate inside the table 1. The main bending roller 4 and auxiliary bending roller 5 at the top of the rotating disk 3 rotate with the rotating disk 3, and the flue gas duct is placed between the main bending roller 4 and the auxiliary bending roller 5. The duct is bent and formed by the rotation of the main bending roller 4 and the auxiliary bending roller 5. During the process of the duct passing between the main bending roller 4 and the auxiliary bending roller 5, the duct will be cleaned by the cleaning component on the upper surface of the table 1 to ensure that the duct surface is clean during the bending process and to ensure the forming quality.

[0030] Reference Figure 1 - Figure 5 The cleaning component includes a fixed frame 901, the lower surface of which is fixedly connected to the upper surface of the countertop 1. A motor 902 is fixedly connected to the upper surface of the fixed frame 901. The output end of the motor 902 is rotatably connected to the inside of the fixed frame 901 and fixedly connected to a disc 903. A short column 904 is fixedly connected to the bottom end of the disc 903. A rectangular frame 905 is slidably connected to the outer wall of the short column 904. A sliding rod 907 is fixedly connected to the outer wall of the rectangular frame 905. A limit block 906 is slidably connected to the outer wall of the sliding rod 907. A connecting frame 908 is fixedly connected to the outer wall of the limit block 906. A cleaning block 909 is fixedly connected to the lower surface of the connecting frame 908.

[0031] Specifically, during use, motor 902 is started, which causes disc 903 to rotate, thereby causing short column 904 to rotate. Short column 904 rotates and slides on the inner wall of rectangular frame 905, and through rectangular frame 905, sliding rod 907 moves back and forth and slides on the inner wall of limit block 906. The movement of limit block 906 drives connecting frame 908 to move, and the reciprocating movement of connecting frame 908 drives cleaning block 909 to move back and forth. The reciprocating movement of cleaning block 909 cleans the side wall of the pipe, achieving the effect of cleaning the side wall of the pipe. This can reduce scratches and wear caused by impurities during bending, and ensure the quality of flue gas duct bending.

[0032] Reference Figure 1 - Figure 2 The main bending roller 4 is located at the center of the rotating disk 3, and the main bending roller 4 and the auxiliary bending roller 5 are the same size.

[0033] Specifically, the main bending roller 4 is set at the center of the rotating disk 3. The main bending roller 4 and the auxiliary bending roller 5 are the same size, so that the main bending roller 4 and the auxiliary bending roller 5 are subjected to more balanced force, and the force on the pipeline is evenly distributed, avoiding uneven bending deformation of the pipeline due to force deviation, and improving the stability of the bending process.

[0034] Example 2

[0035] Reference Figure 1 - Figure 5 A vertical plate 911 is fixedly connected to the upper surface of the tabletop 1. A sliding column 912 is slidably connected inside the vertical plate 911. A U-shaped frame 914 is fixedly connected to the outer wall of the sliding column 912. A cleaning cotton tube 915 is rotatably connected inside the U-shaped frame 914. A spring 913 is slidably connected to the outer wall of the sliding column 912. One end of the spring 913 is fixedly connected to the inner wall of the vertical plate 911, and the other end of the spring 913 is fixedly connected to the inner wall of the U-shaped frame 914.

[0036] Specifically, when bending the pipe, the pipe is passed between the main bending roller 4 and the auxiliary bending roller 5. Through the main bending roller 4 and the auxiliary bending roller 5, the side wall of the pipe will come into contact with the cleaning cotton tube 915. At the same time, the spring 913 generates a pushing force on the U-shaped frame 914, so that the cleaning cotton tube 915 always fits against the side wall of the pipe. When the pipe moves, it achieves the effect of cleaning the side wall of the pipe, which helps to reduce impurities on the side wall of the pipe and ensures the quality of the bending of the flue gas duct.

[0037] Example 3

[0038] Reference Figure 6 - Figure 7 The interior of the upright plate 911 is rotatably connected to a threaded rod 101. One end of the threaded rod 101 is fixedly connected to a limiting piece 102, and the other end of the threaded rod 101 is fixedly connected to a handwheel 104. The outer wall of the limiting piece 102 is rotatably connected to a cylinder 103, and the outer wall of the cylinder 103 is fixedly connected to the interior of the U-shaped frame 914.

[0039] Specifically, when the position of the cleaning cotton tube 915 needs to be adjusted, the handwheel 104 is rotated. The rotation of the handwheel 104 drives the threaded rod 101 to rotate. As the threaded rod 101 rotates inside the vertical plate 911, it causes the threaded rod 101 to move inward, which in turn causes the limiting plate 102 to move inward and rotate on the inner wall of the cylinder 103. The movement of the cylinder 103 drives the movement of the U-shaped frame 914. During this process, the sliding column 912 also moves and slides inside the vertical plate 911. The movement of the U-shaped frame 914 drives the movement of the cleaning cotton tube 915 to achieve its position adjustment. This allows it to adapt to pipes of different specifications, ensuring that the contact force between the cleaning cotton tube 915 and the pipe is appropriate, improving the cleaning effect while avoiding excessive squeezing and damage to the pipe.

[0040] Reference Figure 1 and Figure 4 An electric push rod 11 is fixedly connected to the upper surface of the table 1. The output end of the electric push rod 11 is slidably connected to the inside of the U-shaped frame 6 and fixedly connected to a fixing block 12. There are two electric push rods 11, which are symmetrically arranged on both sides of the U-shaped frame 6. An electric push rod 7 is fixedly connected to the upper surface of the U-shaped frame 6. The output end of the electric push rod 7 is fixedly connected to a fixing block 8.

[0041] Specifically, when bending the flue gas duct, the electric push rod 211 is activated to move the fixing block 212 inward to clamp and fix both sides of the flue gas duct. The two symmetrically arranged electric push rods 211 can avoid the displacement caused by uneven force and enhance the stability of the lateral clamping of the duct. The electric push rod 17 is activated to move the fixing block 18 downward to fix the duct. Applying pressure in the vertical direction and fixing it laterally ensures that no displacement occurs during the bending process.

[0042] Working principle: During use, the flue gas duct is placed between the main bending roller 4 and the auxiliary bending roller 5. Motor 2 is started to rotate the rotating disk 3, causing the main bending roller 4 and the auxiliary bending roller 5 at the top of the rotating disk 3 to rotate with it. The rotation of the main bending roller 4 and the auxiliary bending roller 5 bends the duct. During bending, electric push rod 11 is activated to move the fixing block 12 inward to clamp and fix both sides of the flue gas duct. Electric push rod 7 is activated to move the fixing block 8 downward to clamp and fix the duct. Before bending, start motor 902 to fix the pipe. The start of motor 902 causes the disc 903 to rotate, which in turn causes the short column 904 to rotate. The short column 904 rotates and slides on the inner wall of the rectangular frame 905. The rectangular frame 905 causes the sliding rod 907 to move back and forth and slide on the inner wall of the limiting block 906. The movement of the limiting block 906 drives the connecting frame 908 to move. The reciprocating movement of the connecting frame 908 drives the cleaning block 909 to move back and forth. The reciprocating movement of the cleaning block 909 cleans the side wall of the pipe.

[0043] When the pipe is bent, it is passed between the main bending roller 4 and the auxiliary bending roller 5. Through the main bending roller 4 and the auxiliary bending roller 5, the side wall of the pipe will come into contact with the cleaning cotton tube 915. At the same time, the spring 913 generates a pushing force on the U-shaped frame 914, so that the cleaning cotton tube 915 always fits against the side wall of the pipe, achieving the effect of cleaning the side wall of the pipe when the pipe moves.

[0044] When the position of the cleaning cotton spool 915 needs to be adjusted, the rotating handwheel 104 drives the threaded rod 101 to rotate. As the threaded rod 101 rotates inside the vertical plate 911, it causes the threaded rod 101 to move inward, which in turn causes the limiting plate 102 to move inward and rotate on the inner wall of the cylinder 103. The movement of the cylinder 103 drives the movement of the U-shaped frame 914, which in turn drives the movement of the cleaning cotton spool 915 to achieve its position adjustment.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
