Special-shaped cable core forming mechanism

A special-shaped cable core forming mechanism, characterized by comprising a guide assembly, a first pre-stranding assembly and a main stranding mold which are arranged successively at a same horizontal axis;

• wherein the first pre-stranding assembly comprises a first tapered support, a first rotating connector, a first pull rod and a first strand cylinder;
• the horizontal axis passes through the first tapered support, the first rotating connector and the first strand cylinder in order, and the first pull rod is connected with the first rotating connector and the first strand cylinder;
• the first tapered support is hollow and has two communicated end faces, and a large-diameter end of the first tapered support is fixed to the guide assembly;
• the first rotating connector comprises a front end and a back end, and the front end of the first rotating connector is fixedly connected with a small-diameter end of the first tapered support;
• a stranded through hole layer is provided at a center of the back end of the first rotating connector, and the stranded through hole layer is collinear with the horizontal axis;
• a first annular groove is arranged at an inner side of the back end of the first rotating connector;
• a first annular hollow is arranged at the back end of the first rotating connector, and the first annular hollow corresponds to the first annular groove;
• and
• a first seizing ball is arranged on one end of the first pull rod, and the first seizing ball and the first annular groove are in sliding fit;
• one end, on which the first seizing ball is arranged, of the first pull rod movably passes through the first annular hollow, and the other end of the first pull rod is fixedly connected with the first strand cylinder.
