Tube twisting machine is a kind of power cord, earphone wire, electronic wire and other core wire twisted together cable equipment. Below, we will explain the suburbs and counties of the pipe winch and what is twisting. For those who want to learn, let's learn about the principle of pipe winch and the definition of lay length!
The main principle of the pipe twisting machine is that after the copper wire passes through the twisting bow on the twisting machine, each copper wire is spirally wound from the twisting bow through a circular motion. Stranded copper wire is the use of a copper wire. Copper wires of different specifications are twisted into a conductor with a larger diameter in a certain arrangement order and stranding spacing. The stranded conductor is much softer than a copper wire with the same diameter and has good bending performance.
Definition of pipe winch
The single wires appear at regular intervals in the direction along the strands, which is the pitch of the strands (referred to as the strand pitch for short). Another definition of torsion distance is the vertical distance of the torsion wire body every 360 degrees of rotation along the torsion axis, in mm, which is pitch in English.
The wire harness is twisted together by a plurality of single wires. Generally speaking, the single wire of the wire harness is many and thin, which increases the flexibility of the wire and cable, and also improves the reliability of the line connection. In order to improve flexibility and reliability, the conductors of some wires and cables are twisted.
In order to bundle or strand the single wire at a certain spiral rising angle (or pitch), the equipment meets the following requirements. One is to make all the single lines rotate around the central axis of the device. The other is to make the twisting product move in a straight line. By changing the combination of these two movements, the size of the spiral rise angle can be adjusted to make the produced stranded wire and wire harness meet the structural requirements.
The pipe winch is composed of the main parts of the pay-off, traction, pay-off and coiling, drag and drive system, and control system. In addition, it also comes with cutting boards, side-by-side (also known as pressure dies), instruments and other devices.
The specification of the stranded wire produced by the pipe winder is relatively large. When making the stranded wire, except for a single wire in the center, the remaining single wire discharge disk is placed in the discharge part (such as the twisted cage). Through its rotation, the single wire forms a stranded layer around the central single wire. According to the number of twisted strands and the number of single threads in each layer, the general twisting machine is respectively provided with a plurality of rotating (several segments) drawing parts, and each layer can make different strands, so it is especially suitable for the production of concentric layer twisting. The wire harness produced by the pipe winch is small in size, and the wire harness is formed by the rotation of the basket and the rotating body of the wire take-up part. Since the action of the pipe winch is in the take-up part, the position of the pipe winch mechanism is limited because it is installed on the rotating basket. Therefore, although the yarn winder can only produce a product with a small specification in the twisting direction, the number of the single wires to be bundled can be flexibly arranged as needed.
