[0027] Working principle: when the double-core non-independent butterfly cable is initially formed, firstly, it passes through a first guide hole 702 on a first guide plate 701, the first guide hole 702 has two groups, which can respectively guide the two wire cores in the initial stage, so that the wire core enters according to the predetermined direction, avoids the wire core from deviating or winding in the initial stage, and lays a foundation for subsequent forming processes. After the wire core is guided through the first guide hole 702, the wire core passes through a connecting through hole 703 in the middle of the sliding block 5, the sliding block 5 is sleeved on the outer surface of the supporting long rod 4 and can slide in the rectangular groove 3. When the butterfly cable is pulled by external force or the tension changes due to production speed fluctuation during the forming process, the change of the tension is transmitted to the sliding block 5. If the tension suddenly increases, the sliding block 5 slides upward on the supporting long rod 4, at this time, the connecting spring 6 is stretched, and the stretching process of the connecting spring 6 absorbs part of the energy of the tension, thereby playing a buffering role, avoiding stress concentration of the wire core due to excessive tension, and preventing the wire core from breaking. If the tension is insufficient, the sliding block 5 slides downward under the elastic restoring force of the connecting spring 6, so that the butterfly cable maintains an appropriate tension state, avoiding the problems of cable relaxation and winding. Through the sliding of the sliding block 5 on the supporting long rod 4 and the stretching and contraction of the connecting spring 6, the dynamic adjustment of the tension of the butterfly cable is realized, the stability of the tension of the butterfly cable in the whole forming process is ensured, and then the wire core continues to advance, passes through a second guide hole 705 on a second guide plate 704, the second guide hole 705 also has two groups, further accurately guides the direction of the wire core, and ensures that the wire core is in the accurate position and direction before entering the positioning mechanism 8, thereby improving the accuracy of subsequent positioning and forming. After the wire core passes through the second guide hole 705, the wire core reaches the positioning mechanism 8. Firstly, the wire core contacts the horn guide sleeve 804 on one side of the arch bridge 802, the horn shape of the horn guide sleeve 804 can more conveniently guide the wire core to smoothly enter the positioning channel 803. The positioning channel 803 is a space formed between the positioning frame 801 and the arch bridge 802, and the size and shape thereof are matched with the forming requirements of the double-core non-independent butterfly cable. The wire core is accurately positioned in the positioning channel 803, so that the spacing and arrangement between the double cores meet the predetermined specifications. The two groups of wire cores passing through the positioning channel 803 enter the forming mold (not shown in the figure) under the action of force, so as to realize the integrated forming of the wire core.
