Commonly used stranding machines include tubular stranding machines, rigid frame stranding machines, cage stranding machines, disc stranding machines, fork stranding machines, etc., with different production capacities.
Tubular stranding machine: a production equipment that relies on the rotary motion of a tubular rotary body to complete the function of stranding. The floating frame for placing each pay-off reel is installed on the axis of the revolving body. Driven by the pay-off frame, the floating frame only swings but does not rotate. The take-up device is installed outside the rotary body. Generally, the pipe stranding machine has 1+6 pay-off reels and 1+12 pay-off reels. Tubular stranding machine is suitable for producing 7, 19 (secondary stranding) small conductive wire cores. The stranded section varies according to its model. The G200 type can generally reach 35mm2, and the G400 type can generally reach 70mm2. More than 70mm2 is rarely produced with a tubular stranding machine.
Rigid frame stranding machine: due to the frame structure, the central shaft does not bear the weight of the coil, the equipment has high rigidity and strength, good overall performance, small turning radius and fast production speed. Frame twisters cannot be twisted. When twisting the wires, the single wires will generate internal stress due to twisting, which will cause the high-strength round wires to not be twisted tightly and tend to loose strands. Therefore, some frame-type stranding machines are equipped with a pre-deformation device before the stranding cage to eliminate the internal stress of the single wire. Tension control adopts mechanical friction or pneumatic method, and the upper plate adopts electric worm gear fast clamping or manual hand wheel clamping.
Cage stranding machine: Due to the very large radius of gyration and the complex structure of the untwisting device, the production speed of the cage stranding machine is limited. Stranded or unstranded, suitable for all kinds of insulated cores. Good tension control can give full play to its use effect during use, and become a very superior wire-making mechanical equipment. The performance of this product has also been recognized and praised by many people. In the process of use, its advantages are better played, and the scope of use is becoming wider and wider. In the process of application, it has become a very common advantage to better meet the needs of use. The product is now in use. .
Winding machine: a production equipment that completes the twisting function through the rotation of the winch. The cantilever shaft of each pay-off reel must be symmetrically installed around the axis of the rotary trolley according to certain rules, that is, installed on the outer circumference of the rotary trolley. The axis of each pay-off reel is parallel to the axis of the rotary winch, and each pay-off reel rotates together with the winch. move. There are vertical and horizontal points.
Fork winch: a production equipment that relies on the rotation of a rigid winch to complete the function of twisting the wire. The support for placing each pay-off reel is fixed on the gallows and cannot float. It got its name because the bracket of the pay-off reel is shaped like a fork. There are generally several sections, and the common ones are 3 and 5 sections. It is simpler than a cage stranding machine and has similar production capacity. It can only be seen in large and medium-sized wire and cable factories.
