The end of the cutter disc 1 away from the main shaft 2 is slidably installed with a cutter 41 and a support roller 51. The cutter 41 and the support roller 51 are relatively arranged with respect to the central axis of the stainless steel tube 11 and both rotate with the cutter disc 1. The cutter 41 and the support roller 51 are arranged in the same plane. As the cutter disc 1 rotates, the sleeve 3 can drive the cutter 41 and the support roller 51 moves along the radial direction of the stainless steel pipe 11, and a support bearing assembly 8 is also fixedly installed at the center of the cutter head 1. The support bearing assembly 8 is used to support the stainless steel pipe 11. The support bearing assembly 8 includes a clamping support tube 84, which is rotatably connected to the cutter head 1. The clamping support tube 84 and the stainless steel pipe 11 do not rotate with the cutter head 1. A second accommodating cavity 841 is provided inside the clamping support tube 84, and two groups of clamping blocks 843 are elastically connected in the second accommodating cavity 841. The two groups of clamping blocks 843 are relatively arranged with respect to the axis of the stainless steel pipe 11 and can The clamping support tube 84 can be passed through, and a clamping tile 844 is fixedly installed on one end of the clamping block 843 near the stainless steel tube 11. The clamping tile 844 is a circular arc sheet. The diameter of the circular arc of the inner wall of the clamping tile 844 is the same as the outer diameter of the stainless steel tube 11, so that the inner walls of the two groups of clamping tiles 844 and the outer wall of the stainless steel tube 11 remain in contact when clamping. The two groups of clamping tiles 844 move toward each other to clamp the stainless steel tube 11, so that the stainless steel tube 11 remains stable during the cutting operation, preventing the stainless steel tube 11 from shaking and causing deviations during the cutting process.
[0039] Among them, when the cutter 41 and the support roller 51 are not in contact with the stainless steel tube 11, the upper half of the clamping block 843 is located in the first accommodating chamber 311, and the tube clamping tile 844 does not clamp the stainless steel tube 11; when the bottom end of the cutter 41 abuts against the stainless steel tube 11, the support roller 51 also abuts against the stainless steel tube 11, the clamping block 843 is located in the second accommodating chamber 841, and the tube clamping tile 844 clamps the stainless steel tube 11; when the cutter 41 cuts the stainless steel tube 11, the support roller 51 remains in contact with the stainless steel tube 11, and the clamping block 843 is still located in the second accommodating chamber 841, so that the tube clamping tile 844 remains clamped against the stainless steel tube 11.
[0040] Further, the sleeve 3 is rotatably sleeved with a first support cylinder 10, and the first support cylinder 10 is bolted and installed with a first sliding adjustment block 91 and a second sliding adjustment block 92. The first sliding adjustment block 91 and the second sliding adjustment block 92 are symmetrically arranged about the central axis of the stainless steel pipe 11 and are both located in the cutter disc 1. The first sliding adjustment block 91 and the second sliding adjustment block 92 both rotate with the cutter disc 1. The first sliding adjustment block 91 is slidably connected to the first wedge block 6, and the second sliding adjustment block 92 is slidably connected to the second wedge block 7. The first wedge block 6 and the second wedge block 7 are slidably installed on the cutter disc 1, and the first wedge block 6 is bolted and installed. A cutter slider 4 is fixedly installed, and the cutter 41 is fixedly installed on the cutter slider 4. The cutter 41 is fastened to the cutter slider 4 by a pin shaft, that is, the cutter 41 does not rotate during the cutting process. When in use, the position of the cutter 41 on the cutter slider 4 can be adjusted, and the appropriate cutter 41 can be replaced on the cutter slider 4 to be suitable for stainless steel pipes 11 of various diameters and materials. The first sliding adjustment block 91 can push the first wedge block 6 to move radially along the stainless steel pipe 11, thereby driving the cutter disc 1 to move radially along the stainless steel pipe 11, so as to realize the cutting of the stainless steel pipe 11 by the cutter 41.

The second sliding adjustment block 92 can push the second wedge block 7 to move radially along the stainless steel pipe 11 until the support roller 51 abuts against the outer wall of the stainless steel pipe 11. During the cutting process, the support roller 51 maintains abutment against the outer wall of the stainless steel pipe 11. Similarly, during use, the position of the support roller 51 on the support roller slider 5 can be adjusted, and the suitable support roller 51 can be replaced on the support roller slider 5 to be suitable for stainless steel pipes 11 of various diameters and materials.
[0042] The longitudinal section of the first sliding adjustment block 91 is "L"-shaped, and a first cutter action surface 911 is provided on the side of the first sliding adjustment block 91 close to the stainless steel tube 11, and a second cutter action surface 61 is provided on the first wedge block 6 corresponding to the first cutter action surface 911, and the first cutter action surface 911 and the second cutter action surface 61 are both inclined surfaces.

When the support roller 51 abuts against the outer wall of the stainless steel pipe 11, the horizontal section of the first support roller action surface 921 remains in contact with the horizontal section of the second support roller action surface 71. At this time, the support roller 51 no longer moves radially along the stainless steel pipe 11, and the support roller 51 remains in contact with the outer wall of the stainless steel pipe 11.
