[0003] In the existing device, after the copper wire enters the die, it enters from the entrance area with a larger diameter under the pulling force of the traction device. When passing through the compression area, the copper wire undergoes plastic deformation under the extrusion of the die hole wall, and the diameter gradually decreases. In the sizing area, the copper wire is further trimmed to ensure that it reaches the precise target diameter, and finally comes out from the exit area.

[0004] When the diameter of the copper wire is gradually reduced, scratches will appear on the surface of the copper wire, affecting the quality of the copper wire. In addition, the mold needs to be changed back and forth each time the diameter of the copper wire is changed, which is troublesome. Summary of the invention

10. The anti-winding copper wire automatic intermediate drawing equipment and intermediate drawing process according to claims 1-9, characterized in that: The specific steps are as follows: S1: The copper wire (105) in the unwinding drum (104) passes through the extrusion column (406) and is connected to the winding drum (103), and the No. 1 motor (107) is started to drive the winding drum (103) to reel. When the winding drum (103) moves, it drives the turntable (5) to rotate. The turntable (5) drives the head end of the No. 1 crank (502) to move in a circle. The end of the No. 2 crank (502) pulls the No. 2 crank (503) to move left and right. The No. 2 crank (503) pulls the sliding rod (505) to move left and right through the connecting frame (504). The sliding rod (505) The sliding column on the outside is slidably connected to the inside of the wedge-shaped slide groove (507), and when the sliding rod (505) moves left and right, it drives the sliding squeeze inside the wedge-shaped slide groove (507), so that the sliding block (506) moves forward and backward. The sliding block (506) pulls the components inside the slider (2) and the fixed sleeve (203) through the connecting rod (508) and the fixed block (509) to move forward and backward, so that the squeezing column (406) inside the fixed sleeve (203) drives the copper wire (105) to move forward and backward, so that the copper wire (105) is evenly wound in the winding drum (103); S2: When the components inside the slider (2) and the fixed sleeve (203) move forward and backward, the tooth plate (301) is fixedly connected to the first fixed rod (3), and the second tooth ring (306) inside the fixed sleeve (203) moves forward and backward to mesh with the tooth plate (301), thereby driving the second tooth ring (306) to rotate forward and backward. The second tooth ring (306) drives the second fixed rod (307) and the brush plate (308) to perform forward and reverse circular motions to clean the surface of the extrusion column (406) to prevent copper chips on the surface of the extrusion column (406) from sticking to the surface of the extrusion column (406) and scratching the copper wire (105); S3: When the components inside the slider (2) and the fixed sleeve (203) move forward and backward, the oil tank (303) on the top of the fixed sleeve (203) moves forward and backward together with the fixed sleeve (203). When the oil tank (303) moves forward and backward, it squeezes the piston (302) back and forth. When the piston (302) is squeezed, the piston (302) pushes the gas into the oil tank (303). Because a one-way valve (304) is provided, the pressure inside the oil tank (303) increases, and then the oil is automatically sprayed out from the oil outlet nozzle (305) to lubricate and cool the surface of the copper wire (105). When the piston (302) is stretched, the one-way valve (304) opens to allow the gas to enter. S4: starting the second motor (4) to drive the first gear ring (202) to rotate through the first gear (401), the first gear ring (202) rotates to drive the plurality of second gears (402) to rotate, the second gear (402) drives the outer threaded sleeve to rotate, the threaded sleeve drives the screw (403) to move toward the middle of the fixed sleeve (203), the screw (403) drives the fixed plate (404) and the extrusion column (406) to move toward the middle of the fixed sleeve (203), and at the same time, adjusting the distance between the plurality of extrusion columns (406) and the copper wire (105) to facilitate adjustment of the required size of the copper wire (105), by setting the extrusion column (406), the head end of the extrusion column (406) is small and the tail end is large, forming a tapered barrel shape, which facilitates the central pulling of the copper wire (105) and reduces the occurrence of breakage and scratches on the copper wire (105).
