Overview of wire and cable manufacturing process
The manufacture of wire and cable is totally different from that of most mechanical and electrical products. Mechanical and electrical products are usually assembled into parts, multiple parts re-assembled into a single product, the number of products or pieces measured. Wire and cable are basic units of measurement. All wires and cables are made of insulating, shielding, cabling, sheathing, etc. on the outer surface of the conductor layer by layer. The more complex the product structure is, the more superimposed layers will be.
一. Process characteristics of wire and cable products manufacturing:
1. long continuous stacking combined production mode
The influence of the large-length continuous stacking combined production mode on the wire and cable production is global and controllable, which involves and affects:
(1) production process and equipment layout
All kinds of equipment in the production workshop must be discharged according to the technical process required by the product, so that the semi-finished products in each stage can be transferred in sequence. The equipment configuration should balance the production capacity in consideration of different production efficiencies. Some equipments may have to be equipped with two or more units in order to balance the production capacity of the production line. Therefore, the reasonable combination of equipment and the layout of the production site must be balanced and comprehensively considered according to the product and production volume.
(2) production organization management
Production organization and management must be scientific, reasonable, careful, accurate, strict and meticulous, the operator must be meticulous in accordance with the requirements of the process, any link of the problem, will affect the smooth process, affect the quality of products and delivery. Especially multi-core cable, a pair of lines or basic unit length is short, or quality problems, the whole cable will be insufficient length, resulting in scrap. Conversely, if the length of a unit is too long, it must be sawn for waste.
(3) quality management
The production mode of large-length continuous superposition combination will make any link and instantaneous problems occur in the production process, which will affect the quality of the whole cable. The more quality defects occur in the inner layer, and the failure to detect the termination of production in time, the greater the loss. Because the production of wires and cables is different from that of assembled products, they can be disassembled, reinstalled and replaced; the quality problems of any part of the wires and cables or the process are almost irreparable and irreparable to this cable. Handling afterwards is very negative, not sawing short or downgrading, or scrapping entire cables. It can't tear apart the reload.
The quality management of wire and cable must be carried out throughout the whole production process. The quality control inspection department should inspect the whole production process on a tour, the operator self-inspection, and the upper and lower working procedures to check each other. This is an important guarantee and means to ensure product quality and improve the economic efficiency of enterprises.
2. there are many production processes and large material flow. Wire and cable manufacturing involves a wide range of processes, from non-ferrous metal smelting and pressure processing, to plastics, rubber, paint and other chemical technology; fiber wrapping, weaving and other textile technology, to metal wrapping and metal strip longitudinal wrapping, welding metal forming processing technology and so on.
All kinds of materials used in wire and cable manufacturing are not only in categories, varieties, specifications, but also in large quantities. Therefore, the dosage, dosage, batch period and volume of various materials must be approved. At the same time, the decomposition, recycling, reuse and waste disposal of waste products, as an important part of management, do a good job in material quota management, pay attention to saving work.
In wire and cable production, from raw materials and various auxiliary materials in and out of storage, the flow of semi-finished products in each process to the storage of products, factory, large flow of materials, must be reasonable layout, dynamic management.
3. more dedicated equipment
Wire and cable manufacturing uses special production equipment with the characteristics of the industry process to meet the structural and performance requirements of cable products, to meet the requirements of large-length continuous and high-speed production, thus forming a series of special equipment for cable manufacturing. For example, extrusion machine series, wire drawing machine series, stranding machine series, wrapping machine series, etc.
The manufacturing process of wire and cable is closely related to the development of special equipment and promotes each other. New process requirements, promote the emergence and development of new dedicated equipment; in turn, the development of new dedicated equipment, and improve the promotion and application of new technology. Such as wire drawing, annealing, extrusion series line, physical foaming production line and other special equipment, promote the development and improvement of wire and cable manufacturing process, improve the cable product quality and production efficiency.
