[0025] Working principle: After the drawing machine 1 has completed the drawing operation on the copper material, the motor 41 is started to make the rotating shaft 42 drive the lower shaping wheel 43 to rotate, thereby accelerating the copper tube 3 passing through the upper shaping wheel 414 and the lower shaping wheel 43. At the same time, the rotational friction of the lower shaping wheel 43 on the surface of the copper tube 3 makes the surface of the copper tube 3 smoother. By rotating the pull rod 49, the turntable 46 drives the upper lower shaping wheel 43 to rotate, thereby adjusting the gap between the upper shaping wheel 414 and the lower shaping wheel 43, thereby adjusting the thickness of the copper tube 3. At the same time, it also makes the cross-section of the copper tube 3 closer to a circle.

[0026] When the rotating disk 46 is driven to rotate by the pull rod 49, the bevel gear 51 is also rotated to be buckled with the bevel buckle rod 55, so that the bevel buckle rod 55 fixes the rotation angle of the bevel gear 51. Thus, the fixing mechanism 5 fixes the working state of the adjustment mechanism 4. When the angle of the lower shaping wheel 43 needs to be adjusted, the bevel buckle rod 55 and the bevel gear 51 are released from the buckle connection by rotating the handle 54, so that the rotating disk 46 can be driven by the pull rod 49 to slide on the inner wall of the collar 47, thereby adjusting the rotation angle of the lower shaping wheel 43.

[0027] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
