Description
Technical Field
[0001] The utility model relates to the technical field of water pipe cutting, in particular to a PE water supply pipe cutting machine. Background Technique
[0002] Water pipes, as an important part of modern urban infrastructure, have a long history and technical background. From the initial simple design to the current complex systems, they have evolved over several centuries. The evolution of water pipe technology not only reflects human understanding and needs for water resource management but also embodies the comprehensive progress of materials science, engineering, and environmental science. As an indispensable tool in the field of pipeline installation and maintenance, with the widespread application of electric motors, electric cutting machines came into being, marking a major leap in water pipe cutting technology. Electric cutting machines drive the cutting wheel or saw blade to rotate at high speed through an electric motor, greatly improving the cutting speed and accuracy. Using a metal cutting wheel can effectively cut various metal pipes, such as steel pipes and copper pipes. In addition, the introduction of electric cutting machines has also reduced the labor intensity of operators and improved the efficiency of pipeline installation and maintenance.
[0003] However, during the operation of a handheld cutting machine, due to the limitations of manual control, there may be deviations in cutting accuracy, resulting in an uneven cutting surface or dimensions not meeting the requirements, which in turn affects subsequent assembly operations. Large cutting machines cannot be mobilized to the site for deployment due to factors such as their size, greatly affecting the progress. Content of the Utility Model
[0004] The purpose of the utility model is to provide a PE water supply pipe cutting machine to solve the problems raised in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A PE water supply pipe cutting machine includes a main body.

Lower support arms are connected to both sides of the main body, and upper support arms are connected above the lower support arms. A fixed rod is connected to one side of the upper support arm, and a machine box is installed on the fixed rod. An up-and-down pull rod device is installed on the machine box. A moving column is installed on the machine box. A connecting arm is installed at the lower end of the moving column. A guide post is installed on the left side of the connecting arm, and a positioning roller is connected to the guide post. A cutting device is connected to the right side of the connecting arm.
[0006] Preferably, two rollers are installed above the main body. The first roller and the second roller can rotate when cutting a water pipe to ensure uniform cutting.
[0007] Preferably, the moving column can only move up and down on the machine box.
[0008] Preferably, the positioning roller is connected to the guide post and can move up and down within a certain range through a spring inside the guide post.
[0009] Preferably, an upper and lower pull rod device is installed on the machine box. By pulling the pull rod, the force brought by the circular motion is changed into the force of up and down motion by the rotating shaft on the pulling device to drive the moving column to move up and down.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0017] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0018] Embodiment: Please refer to Figures 1-3, the present utility model provides a technical solution: a PE water supply pipe cutting machine, including a main body 1. A groove is opened at the top of the main body 1. A first roller 3 is installed on the left side of the groove, and a second roller 2 is installed on the right side of the groove. Lower support arms 4 are connected to both sides of the main body 1. Upper support arms 5 are connected above the lower support arms 4. A fixing rod 6 is connected to one side of the upper support arm 5. A machine box 7 is installed on the fixing rod 6. An upper and lower pull rod device 9 is installed on the machine box 7. A moving column 8 is installed on the machine box 7. A connecting arm 13 is installed at the lower end of the moving column 8. A guide post 12 is installed on the left side of the connecting arm 13. A positioning roller 10 is connected to the guide post 12. A cutting device 11 is connected to the right side of the connecting arm 13.
[0019] Among them, two rollers are installed in the groove above the main body 1. The first roller 3 and the second roller 2
[0020] In this embodiment, the water pipe can be rotated during cutting to ensure uniform cutting.
[0021] Among them, the moving column 8 can only move up and down on the machine box 7.
[0022] In this embodiment, the moving range of the moving column is fixed, and the accuracy will not be affected due to left and right movement.
[0023] Among them, the positioning roller 10 is connected to the guide post 12 and can move up and down within a certain range through the spring in the guide post 12.
[0024] In this embodiment, it is ensured that the water pipe can be effectively fixed during cutting without affecting the cutting of the cutting blade.
[0025] Among them, an upper and lower pull rod device 9 is installed on the machine box 7. By pulling the pull rod, the force brought by the circular arc movement can be changed into the force of up and down movement by the rotating shaft on the pulling device 9 to drive the moving column 8 to move up and down.
[0026] In this embodiment, the up and down movement of the moving column drives the cutting blade to make a vertical movement, so that the height can be adjusted according to the size of the water pipe during actual work.
[0027] Working principle: When cutting a water pipe is required, the operator first pulls the pull rod to move the moving column up and down, and then drives the positioning roller to reach the appropriate position to ensure that the water pipe can be accurately fixed. The positioning roller is in close contact with the water pipe. Combined with the support of the first roller and the second roller, a stable positioning is provided for the water pipe together, so that it will not shift during the cutting process.
[0028] Next, start the cutting device. As the cutting blade rotates, the water pipe makes an accurate rotational movement at a fixed position under the coordinated action of the first roller, the second roller and the positioning roller. This design ensures the stability during the cutting process and the uniformity of the cutting surface, and avoids problems such as uneven cutting or dimensional deviation.
[0029] During the continuous cutting process, the cutting disc gradually penetrates into the water pipe until it is completely cut off. The entire cutting process is not only efficient, but also due to the precise control of the rollers, it ensures the flatness of the cutting surface and the accuracy of the dimensions, meeting the requirements of high-quality cutting.
[0030] Through this operation process, this PE water supply pipe cutting machine not only simplifies the operation steps, improves the cutting efficiency, but also ensures the accuracy and safety of the cutting operation, and is applicable to the cutting operations of water pipes of different sizes and types.
