[0002] Cast iron pipe is essentially ductile iron pipe. It is called ductile iron pipe because it has the essence of iron and the performance of steel. In ductile iron pipe, the graphite exists in a spherical form. Generally, the size of the graphite is grade 6-7. In terms of quality, the spheroidization grade of cast iron pipe is required to be controlled at grade 1-3, and the spheroidization rate is ≥80%. Therefore, the mechanical properties of the material itself are well improved. It has the essence of iron and the performance of steel. After annealing, the metallographic structure of ductile iron pipe is ferrite with a small amount of pearlite. It has good mechanical properties, so it is also called cast iron pipe.

Moving wheels 7 are installed on both sides of the bottom left side of the moving frame 4, and moving wheels 7 are installed on both sides of the bottom right side of the moving frame 4. Each component has a drive wheel 8, which enables the mobile frame 4 to move the ductile iron pipe towards the cutting mechanism. This allows the ductile iron pipe to be moved to the bottom of the cutting mechanism, facilitating its cutting. By continuously moving the mobile frame 4, the ductile iron pipe can be continuously cut by the cutting mechanism after reaching the bottom. A first drive motor 9 is mounted on the top of the mobile frame 4, and a first drive component 10 is mounted on the output end of the first drive motor 9. The first drive component 10 is connected to the drive wheel 8, allowing the first drive motor 9 to drive the first drive component 10, which in turn drives the drive wheel 8 to rotate, thus moving the mobile frame 4.

[0023] Reference Figures 1-2In a preferred embodiment, the cutting mechanism includes a mounting frame 11, which is disposed on the top of the front of the fixed frame 3. A mounting base 12 is mounted on the base of the mounting frame 11, and a cutting blade 13 is mounted on the side of the mounting base 12. A base plate 14 is mounted on the top of the mounting frame 11, and a second drive motor 15 is mounted on the top of the base plate 14. A second drive component 16 is mounted on the output end of the second drive motor 15. The cutting blade 13 is connected to the second drive component 16, so that the mounting frame 11 can mount the cutting blade 13 through the mounting base 12, and the second drive motor 15 can drive the cutting blade 13 to rotate through the second drive component 16, which facilitates the cutting blade 13 to cut the ductile iron pipe. The first drive component 10 and the second drive component 16 include two sets of pulleys and belts sleeved on the surface of the pulleys, which can be driven by the first drive component 10 and the second drive component 16.

[0024] Reference Figures 1-2 In a preferred embodiment, a lifting platform 20 is installed on the top of the fixing frame 3. The lifting platform 20 is disposed in the inner cavity of the fixing frame 3. A track 17 is installed on the surface of the fixing frame 3.

[0026] Specifically, the working process or working principle of this continuous cutting mechanism for ductile iron pipes is as follows: During use, the ductile iron pipe is restrained by the movable frame 4. Then, the first drive motor 9 is started, causing it to drive the drive wheel 8 via the first drive component 10. The drive wheel 8 drives the movable frame 4 to move, moving the ductile iron pipe towards the cutting blade 13, so that the left end of the ductile iron pipe contacts the mounting roller 22. Subsequently, the lifting platform 20 moves the mounting frame 11 downwards, and the second drive motor... When the machine 15 is started, the second drive motor 15 drives the cutting blade 13 to rotate through the second drive component 16. This allows the mounting frame 11 to move the cutting blade 13 downward to cut the ductile iron pipe located at the bottom of the cutting blade 13. After cutting, the first drive motor 9 is started again, causing the moving frame 4 to move the ductile iron pipe continuously to the left. This moves the cutting surface on the left side of the ductile iron pipe to contact the left side of the mounting roller 22, allowing the ductile iron pipe to be cut again, thus facilitating continuous cutting of the ductile iron pipe.

[0027] It should be noted that the first drive motor 9, the second drive motor 15 and the elevator 20 are existing devices or equipment, or devices or equipment that can be implemented by existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
