الوصف
In the production of wire and cable, multiple strands of wire need to be stranded before the insulation can be extruded. The stranding of multi-stranded wires can be carried out on stranding machines or bundling machines. When the diameter of a single wire is very fine, the number of strands is high and the wire is particularly soft, the traditional stranding equipment cannot meet the requirements and a bunching machine can only be used. Multiple single wire pay-off reels are placed in layers and rows on a fixed support and together they enter the main machine via a dividing plate. The rotation of the rotating body twists the single wires and completes the stranding of the wire.
We can offer a wide range of bunching machines for bare copper, tinned copper, silver-plated copper, copper-clad aluminium, special alloy and insulated core wires. Not only can they be used for stranding multi-stranded wires, but they can also replace (1+6) tube stranding and (1+6) frame stranding for regular stranding. Compared to the tube and frame stranding machines, the production capacity of the bunching machine is (2 to 4) times higher.
1. Equipment Features
(1) The user-friendly design makes operation easier and more convenient. Advanced PLC, touch screen and frequency control technology are used. The running program, instructions and machine self-test are all controlled by PLC, which is technologically advanced and reliable in operation.
(2) The professional program design ensures the reliability of the system. The imported magnetic powder clutch is used to control the tension and has a unique automatic tracking and adjusting design, so that the tension of the whole reel is even and consistent, thus the quality of the stranded wire is greatly improved.
(3) The special stranding bow material and unique design ensure that the quality of the stranded wire is not affected during high speed operation. With the latest wire crossing system, the wire enters the bow belt directly from the spindle guide wheel. The bow belt has a unique semi-circular groove design, which protects the wire from wind resistance during high speed operation, so that the stranded wire is no longer scratched or skipped.
(4) The electromagnetic brake is used to brake, and the brake is automatically applied when the wire is broken internally or externally, or when there are various faults.
(5) The whole machine are used synchronous belt drive, the machine without oil, stranded wire from oil pollution.
