7. A method for using a bare copper wire preheater for wire and cable processing, which relates to the bare copper wire preheater for wire and cable processing according to claim 6, characterized in that: The following steps are involved: S1. Installation and connection: initially, the fixed preheating box (2) and the mobile preheating box (3) are in an open state, and the bare copper wire (4) is passed through the front and rear two hollow drums (501) and fastened by the glass bolts (504); S2, moving into position: controlling the motor box (607) and the hollow rotating cylinder (501) to move downward by the electric lifting rod (606), driving the threaded rod (603) to rotate by starting the servo motor 2 (604), and then controlling the motor box (607) and the hollow rotating cylinder (501) to move, and finally moving the bare copper wire (4) to the limiting sleeve; S3, closed heating: the movable box (301) and the fixed box (201) are combined by the electric telescopic rod (305), the connecting block (302) is inserted into the connecting groove (203), and a relatively sealed heating space is formed. At this time, the limiting half-cylinder sleeve 2 (306) and the limiting half-cylinder sleeve 1 (204) are combined into a complete limiting cylinder sleeve, and the electromagnetic connecting block 2 (307) is attached to the electromagnetic connecting block 1 (205). In addition, the connecting rod (2010) is inserted into the socket (303), and the heating machine (201) is started. 06) The sealed heating space is formed by heating the heating wire (202), and during the connection process between the fixed preheating box (2) and the movable preheating box (3), the fixed bar teeth (304) drive the double gear shaft (701) to rotate, so that the movable bar teeth (702) move toward the presser (208), and finally press the presser (208) to magnetically connect the electromagnetic connection block 1 (205) and the electromagnetic connection block 2 (307), thereby strengthening the connection between the fixed preheating box (2) and the movable preheating box (3); S4, pulling the rotating wire: the bare copper wire (4) passing through the hollow drum (501) is limited and fastened by the glass bolt (504), and the bare copper wire (4) is wound on the wire take-up drum (107).
