Description

Technical Field

[0001] The utility model relates to the technical field of copper wire twisting machines, in particular to a twisting device for preventing copper wires from being drawn. Background Art

[0002] A stranding machine is a mechanical device that can be widely used to strand various soft and hard conductors, so that multiple single conductors are twisted into one strand to meet the process requirements of the wire. A copper wire stranding machine is the same as the equipment used to make copper wire. For example, copper wire used as a cable is usually made into a single copper wire by drawing copper materials, and then the single copper wires are combined into a copper wire by a copper wire stranding machine.

[0003] For example, the patent with publication number CN219658456U discloses a copper wire stranding machine, including a machine base, a lead-in disk is fixedly connected to the front end of the top surface of the machine base, and a closing disk is fixedly connected to the top surface of the machine base and located behind the lead-in disk, and a stranding mechanism is also provided on the top surface of the machine base and located behind the closing disk, and the stranding mechanism includes a limit slide bar, a double-headed screw, a stranding seat, a connecting disk, a positioning rod, a driving motor and a stranding disk, a group of front-to-back symmetrical limit slide bars are fixedly connected in the top surface of the machine base, and the double-headed screw is movably connected to the machine through the first rotating rods at both ends. The top surface of the seat is located between the limit sliding rods, and the two stranded wire seats are movably connected to the limit sliding rods through the limit sliding sleeves on both sides of the bottom surface, and the stranded wire seats are also movably connected to the double-headed screw through the connecting block on the bottom surface and located between the limit sliding sleeves. The connecting disk is movably connected to the inner wall of the stranded wire seat through the second rotating rod on the outer wall, and the positioning rod is fixedly connected to the inner wall of the connecting disk.
