The operation board part 81 is arc-shaped, which is also to conform to the state of the copper pipe 4 when it exits the pipe drawing machine 1 at the beginning.

[0038] Further, the bottom of the support column 11 is fixedly connected above the positioning component 8, and the center of the pressing roller 10 is inserted and rotatably connected above the support column 11. The bottom of a plurality of support columns 11 is fixedly connected to one side of the operation board part 81, and the centers of a plurality of pressing rollers 10 are inserted above the plurality of support columns 11.

[0039] Furthermore, a groove portion 101 is provided in the middle of the pressing roller 10. The middle part of the sliding connection copper tube 4 penetrates into one side of the groove portion 101.

[0040] A support column 11 and a pressing roller 10 are provided on the operation panel portion 81. The copper tube 4 is clamped by the groove portion 101 in the pressing roller 10. When the copper tube 4 is pulled by the pipe cutting machine 2, the pressing roller 10 also rolls, and the copper tube 4 can continuously move in the direction of the pipe cutting machine 2 without being resisted.

[0041] Please refer to Figure 6 and Figure 7 Furthermore, a plurality of through-component supports 12 are fixedly connected above the other side of the operation panel portion 81. The through-component supports 12 and the pressing rollers 10 are arranged alternately. A first through-hole portion 121 is provided in the through-component support 12, and the copper tube 4 penetrates and is slidably connected through the first through-hole portion 121.

[0042] Among them, a plurality of through-component supports 12 provided on the other side of the operation panel portion 81 are arranged alternately with the pressing rollers 10, and the copper tube 4 passes through the through-component support 12. In this way, the through-component support 12 and the pressing roller 10 cooperate to gradually straighten the bending degree of the copper tube 4, and at the same time, the through-component support 12 plays a role of support and connection.

[0043] Furthermore, a conical inlet support 13 is fixedly connected above the port of the operation panel portion 81. A second through-hole portion 131 is provided in the conical inlet support 13. At the same time, the second through-hole portion 131 is at the same level as the first through-hole portion 121, and the copper tube 4 penetrates and is slidably connected through the second through-hole portion 131.

[0044] A conical inlet support 13 is provided at the port of the operation panel portion 81. The conical inlet support 13 receives the copper tube 4 coming out of the tube pulling machine 1.

[0045] Working principle:

[0046] A pipe cutting machine 2 is provided behind the pipe drawing machine 1, and a connecting support frame 3 is provided on one side of the pipe cutting machine 2. In this way, after the copper pipe 4 is drawn in the pipe drawing machine 1, it enters the structure above the connecting support frame 3, and then enters the pipe cutting machine 2 from the structure above the connecting support frame 3 for pipe cutting work. The entire copper pipe 4 is in a U-shaped continuous working state when viewed from above. Support blocks 5 are provided on both sides above the connecting support frame 3, and there are four support blocks 5, two on each side. A slide bar 6 is provided between the support blocks 5. A moving seat 7 is sleeved outside one end of the slide bar 6, and a spring 14 is provided between the moving seat 7 and one side support block 5. At the same time, a positioning component 8 is provided above the moving seat 7. In this way, after the moving seat 7 is pulled by an external force, the positioning component 8 will move along with it, and under the action of the spring 14, the moving seat 7 and the positioning component 8 will return to their original positions. An operation board part 81 is provided on one side of the positioning component 8, and a plurality of pressing rollers 10 and a plurality of through parts supports 12 are alternately arranged above the operation board part 81. At the same time, a conical inlet part support 13 is provided at the port of the operation board part 81. When the copper pipe 4 coming out of the pipe drawing machine 1 first enters the conical inlet part support 13, then enters the through part support 12, and is simultaneously clamped into the groove part 101 on one side of the pressing roller 10. In this way, the copper pipe 4 is now placed above the operation board part 81. At this time, the through part support 12 and the pressing roller 10 also straighten the copper pipe 4, that is, perform preliminary straightening work. The copper pipe 4 then passes through the front of the limit baffle 9 on one side of the positioning component 8 and finally enters the pipe cutting machine 2 for pipe cutting work. That is, pipe drawing, guiding and pipe cutting are synchronized, connecting the pipe drawing machine 1 and the pipe cutting machine 2 together.

[0047] In addition, after the copper pipe 4 enters the pipe cutting machine 2, since the pipe may sometimes be insufficiently straightened when the copper pipe 4 is straightened in front during pipe cutting, the moving seat 7 and the structure above it will move along the slide bar 6 towards the pipe cutting machine 2 to play a buffering role. After the copper pipe 4 returns to normal, the spring 14 takes effect and brings the moving seat 7 and the structure above it back to their original positions.
