Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a cable strand forming device. Background Art

[0002] Cables are mainly composed of conductors and plastics. Stranding is the process of twisting single wires of the same or different diameters together in a certain direction and according to rules to form a whole wire core. Wire twisting refers to the process of grouping several cable cores that meet the resistance requirements into groups in a forward direction through mechanical equipment and twisting them into a conductor.

[0003] When optimizing the existing cable strand forming device, most of the optimization efforts are focused on improving the practicality of the cable strand forming device and reducing damage. For example, the Chinese utility model patent application number CN202322665276.9 discloses a "cable production stranding device". In this device, a chassis is provided, wherein the inner surface of the chassis is rotatably connected to a third rotating shaft, and the number of the third rotating shafts is two. A circular ring is fixedly connected between the two third rotating shafts, and the inner surface of the circular ring is fixedly connected to the first rotating shaft, and the outer surface of the first rotating shaft is rotatably connected to a stranding roller. There are two wire rollers and they are distributed front and back. The inner surface of the front twisting roller is rotatably connected to the second rotating shaft, and the right surface of the second rotating shaft is fixedly connected to the second thin rod. By setting the third rotating shaft, the first rotating shaft, the twisting roller, the twisting groove, and the second rotating shaft, the ring can rotate in the direction of the twisting to reduce the wear of the bare wire. At the same time, the twisting roller rotates to follow the twisting, making the twisting smoother, reducing the contact area with the equipment, and reducing the wear caused by pulling. At the same time, the sliding rod, the first thin rod, the second thin rod, and the second rotating shaft are set to facilitate the insertion of the bare wire while the twisting roller rotates the twisting, which is simple to operate.

[0004] Although the above-mentioned cable strand forming device has certain advantages in terms of high practicality and reduced damage, it still has certain disadvantages: the appropriate conductor pitch has an important impact on the cable production cost. A small pitch increases the production cost, and a large pitch not only makes the conductor bite tight and loose, but also easily causes an increase in contact resistance during use, thereby reducing the heating load of the cable conductor. Therefore, it is necessary to select a suitable pitch cylinder according to actual conditions. If the pitch cylinder does not have a convenient disassembly and assembly method, it is easy to damage the pitch component and cause trouble for personnel operation. Utility Model Content
