Production of cable products today is a very dynamic industry. For most of the modern enterprises of Russia, periodic updating of equipment and devices is characteristic, which makes cable products extremely popular.
In this regard, this business is very popular among aspiring businessmen.
A little bit about cable production
In order to satisfy all the needs of the market, it is necessary to organize the manufacture of inexpensive, but high-quality products. In this regard, in the process should use automatic equipment for cable production.
This will ensure high quality that meets not only domestic but also international standards in this area. Such a line consists of a group of machines, each of which performs its function, in the aggregate they represent a complete cycle. The advantage of automatic equipment is to simplify the production process, which is controlled by one operator.
In addition, the performance of such installations is much higher than semi-automatic machines. The manufacture of cable products is a high-tech process. It is produced by twisting threads from a conductive material, applying a wire with subsequent placement in a polymer shell.
All operations are performed by the cable production line. Various materials are used in this process. Thus, conductive threads are made from aluminum and copper, and shells are made from lead and steel. Synthetic plastics and rubber compounds are indispensable components in the manufacture of cable products.
Where to buy the necessary equipment
Today, there are many companies that sell such plants. The scope of their services includes not only the implementation, but also the initial installation and debugging of the line. Due to the fact that the equipment for cable production belongs to high-tech installations, it should be serviced by professionals, not amateurs.
Companies implementing such lines conduct training for personnel who will subsequently manage the process. In addition, the cable manufacturing machine has an affordable price, so not only large enterprises, but also medium and even small companies will be able to acquire it, while the quality of the plants sold is quite high.
What the industrial line consists of
Equipment for the production of wire includes closed mixers, roller machines, calendars, bathtubs for separating crumbs, lamination machines, a cooling line and other special equipment. These units must meet all the requirements of international quality standards, which will ensure their durability and make them convenient to use. Companies involved in the implementation of these lines will always provide customers with competent advice, not only regarding the operation of equipment, but also regarding the process.
Consider in more detail the purpose of the main nodes of the production line.
Extrusion machine
This equipment for the production of VVG cable provides the application of a thin polymer coating (insulation) on a metal core. The main purpose of such a machine is the melting of polymer raw materials, as well as giving the material the necessary shape specified in the extruder.
There are three types of such machines: worm, disk worm and wormless. Their main difference lies in the diameter of the screw and its speed of rotation, in relation to its length to diameter, as well as in geometric characteristics.
Drawing mill
This cable manufacturing equipment is designed to process metals by pulling them through a section with a smaller diameter - drawing method. The main node of such a machine are dies. Metal blanks and special pulling devices stretching raw materials are passed directly through them. In the manufacturing process, drum-type drawing mills can be used. They are characterized by the diameter of the drum. Depending on the machine model, the number of pulling units may vary.
Twisting machine
This cable manufacturing equipment combines the individual elements of manufactured products, such as insulated conductors, wire, strands, in a stable and clear form. It is customary to distinguish the following types of twisting machines: cigar, stand, fork, with a rigid structure, arched, single and general twist. The difference of each type is in the coils used, in the twist step, the number of cores used, in the tension control.
Booking Machine
This equipment is used to wind the cable with various materials designed to protect it from various damages and environmental influences. Steel or corrugated galvanized tape, metal wire or other material can act as armored material.
Cable Coil Machines
This equipment is designed for winding incoming wire of various cross-sections into bays with a certain meter. The main characteristics of such installations are the diameter of the feed drum, the method of recoil, the principle of laying the finished product, the number of revolutions and engine power, as well as the method of cable tension.
Optional equipment
Additional technical installations used in the manufacture of cable products perform secondary procedural tasks and are represented by the following machines: receiving and giving devices, wire rewinding equipment. Depending on the volume of feedstock for the manufacture of cables, it is necessary to use those industrial lines whose technical characteristics will correspond to the declared capacity.
Cable production technology
The manufacturing technology of cable products consists of several stages, providing a full cycle of work. First of all, the preparation of metal cores (copper or aluminum) takes place. This is done by drawing wire of a thicker diameter wound on a huge bay. This process is carried out by pulling it through a series of draggers with tapering consecutive holes.
As a result, conductive wires of the future cable are formed. The next step is coating the metal with insulation. For this, the veins enter the extruder, in which granular polyethylene is preheated to a predetermined temperature. The molten mixture envelops the metal and with it exits through the hole, which provides alignment of the core in the shell.
Next, the resulting wire is cooled by pulling it through a bath, which is irrigated with water. After this, a check is carried out for compliance with diameter, eccentricity, tightness. In addition, the wire is subjected to a 250V insulation test. If it meets all the requirements, it ends up on a winder.
Here, coils of a given length are formed. The entire described cycle occurs in automatic mode, the process can not be stopped. The next operation is twisting the wires in a special twisting machine and making insulation of the finished cable. This process takes place in an extruder. If necessary, you can add a third operation - product reservation. In this case, the cable is coated with a layer of lead or steel.
