Embodiment
[0034] see figure 1 , 2 , in the preferred embodiment of the present invention, the crimping tube pressing unit 200 suitable for catenary hanging string processing is arranged on the bracket 230, and is mainly used for pressing after the crimping tube 220 is matched with the stranded wire. The whole process can be simplified as: twisting One end of the wire passes through the crimping tube 220 and is wound around the outer circumference of the heart-shaped ring, and then the twisted wire end turns to 180° and then passes through the crimping tube 220 (that is, there are two twisted wires that are arranged side by side in the crimping tube 220 at this moment, and A ring structure is formed on one side of the crimping tube 220 ); finally, the crimping tube 220 is pressed together, and the two stranded wires are fixed in the crimping tube 220 .
[0035] Specifically, the crimping tube pressing unit in the preferred embodiment includes a servo motor 201, a reducer 202, and a shaf...
