[0002] Steel-plastic composite pipe, also known as plastic-coated pipe, plastic-coated steel pipe, or plastic-coated composite steel pipe, is a steel pipe with a steel pipe as the base material. A layer of plastic anti-corrosion coating is fused to the inner surface of the steel pipe (base pipe) or to both the inner and outer surfaces through spraying, rolling, dipping, or suction processes. Steel-plastic composite pipe has excellent corrosion resistance and relatively low frictional resistance.

[0003] Existing steel-plastic composite pipe cutting devices generally have non-adjustable clamping inner diameters, which limits their use. When cutting steel-plastic composite pipes of different diameters, multiple cutting machines need to be used separately, resulting in high operating costs and hindering practical industrial production.

[0020] Please see Figure 1 and Figure 2 This embodiment provides a steel-plastic composite pipe cutting and dust removal device, including a fixed base 1, a movable base 2, a positioning sleeve 3, and a cutting unit 4. The fixed base 1 and the movable base 2 are used to install the positioning sleeve 3, the positioning sleeve 3 is used to clamp the steel-plastic composite pipe, and the cutting unit 4 is used to cut the steel-plastic composite pipe.

[0021] The fixed base 1 and the movable base 2 are arranged opposite to each other, with the line connecting the fixed base 1 and the movable base 2 in the first direction, and the movable base 2 can move along the first direction. The fixed base 1 and the movable base 2 are each connected to multiple positioning sleeves 3. The positioning sleeves 3 are semi-cylindrical, with different inner diameters for adjacent positioning sleeves 3, and are detachably connected to each other. Multiple positioning sleeves 3 are connected to form a group. The fixed base 1 and the movable base 2 are each connected to a group of positioning sleeves 3. The two groups of positioning sleeves 3 together form a cylindrical clamping opening 5. The axis of the clamping opening 5 is set along the second direction. The clamping opening 5 is used to clamp the steel-plastic composite pipe. Multiple positioning sleeves 3 with different inner diameters form a group. Different inner diameter positioning sleeves 3 can be installed or removed as needed to change the inner diameter of the clamping opening 5, making it suitable for clamping steel-plastic composite pipes with different inner diameters. The inner diameter of the multiple positioning sleeves 3 can be designed to correspond to the outer diameter of the steel-plastic composite pipe, and then combined and installed together for easy installation, disassembly, and replacement. Preferably, in this embodiment, the fixed seat 1, the movable seat 2, and the positioning sleeve 3 are arranged in two sets along the second direction, so that two supports and fixations can be provided on the steel-plastic composite pipe, making the steel-plastic composite pipe more stable.

[0022] Specifically, the positioning sleeve 3 includes a positioning part 3a and a connecting part 3b. The positioning part 3a is semi-cylindrical, and one end of the positioning part 3a extends outward to form the connecting part 3b. In the same group of positioning sleeves 3, the positioning parts 3a of two adjacent positioning sleeves 3 are coaxially arranged and abut against each other, and the two connecting parts 3b of two adjacent positioning sleeves 3 are detachably connected. Furthermore, the connecting part 3b has a connecting hole 3ba for bolting two adjacent positioning sleeves 3.

The supporting column 8 is dumbbell-shaped, with two connecting plates 9 rotatably connected to its two ends. The end of the connecting plate 9 away from the supporting column 8 is hinged to the fixing plate 6, and the hinge is fixed with bolts. The supporting column 8 is used to support the steel-plastic composite pipe. One end of the steel-plastic composite pipe is placed on the supporting column 8, and the steel-plastic composite pipe is pushed and adjusted to be horizontal at the other end, so that the steel-plastic composite pipe can be pushed into the clamping port 5, making it easier to install the steel-plastic composite pipe.

After the steel-plastic composite pipe is inserted into the clamping opening 5, the movable seat 2 moves towards the fixed seat 1, and the clamping opening 5 tightens and clamps the steel-plastic composite pipe. Then, the steel-plastic composite pipe can be cut. It is very convenient to use. By combining and connecting positioning sleeves 3 with different inner diameters, the cutting device can be applied to steel-plastic composite pipes of different diameters, greatly improving the applicability of the cutting device.
