Description

Technical Field

[0001] The present invention relates to the technical field of wire and cable processing, and in particular to automated processing equipment and a processing technology for producing wire and cable. Background Art

[0002] Wire and cable manufacturing refers to the entire process of processing conductors, insulating materials and other components into wires and cables. This process usually includes multiple processes such as conductor core twisting, insulation layer extrusion, and outer sheath extrusion. Among them, an automatic extrusion equipment for wire and cable manufacturing will be used. Traditional extrusion equipment mostly adopts a staged extrusion process. After the first layer of the conductor core is extruded on the outer wall, it is necessary to wait for the surface of the first layer to completely cool and form before extruding the next layer. This may lead to the following problems in the actual production process:

[0003] 1. Wires and cables need to wait for complete cooling after each layer of coating, which prolongs the production cycle and greatly reduces the overall production efficiency;

[0004] 2. Wires and cables may be contaminated with dust and impurities during the cooling process after each layer of coating, which will lead to poor bonding between the first layer and the second layer, affecting the insulation performance and overall strength;

[0005] 3. The phased process results in a very long extrusion line, which requires more production space to house equipment and cooling areas, increasing plant construction and operating costs;

[0006] 4. The cooling rate of each layer is difficult to control accurately. If the cooling time of the cladding is too long, its surface state may change, affecting the bonding strength with the next cladding;

[0007] 5. Too fast cooling may cause the material to shrink and deform, resulting in stress concentration inside the sheath, increasing the risk of cable breakage or damage during use.
