The copper tube cutting equipment according to claim 1, characterized in that: The feed platform (410) includes several first supports (4110), and the bottom of each of the several first supports (4110) on the side away from the feed chute (420) is provided with a slope structure (4120). The feed chute (420) includes several guide plates (4210), and the several guide plates (4210) are respectively welded to one side of the several first supports (4110), and baffles (4220) are welded to the outer sides of the two outermost guide plates (4210).

4. The copper tube cutting equipment according to claim 1, characterized in that: The guiding mechanism (440) includes a second support (4410) and two guide seats (4420) symmetrically distributed on the top of the second support (4410). Both sides of the top of the second support (4410) are provided with vertically upward extending flanges (4430). Each flange (4430) is threaded with a screw (4440). The inner ends of the two screws (4440) are rotatably connected to the two guide seats (4420) respectively.

5. A method for cutting copper tubes, characterized in that: The copper tube cutting method, applied to the copper tube cutting equipment as described in any one of claims 1-4, comprises the following steps: Step 1: The copper tube to be cut enters the limiting conveying mechanism (200) from the left side of the workbench (100). Under the limiting action of the clamping mechanism (210), it is conveyed by the belt conveyor (220) and finally the cutting mechanism (300) completes the cutting operation. Step 2: In step 1, the copper tube can be fed by the feeding mechanism (400). The cutting length of the copper tube can be adjusted by the length adjustment mechanism (500). The cut copper tube is output through the discharge hole (120).
