Problems solved by technology

[0002] The conventional production process of cable insulation layer and outer sheath adopts insulation extrusion / wrapping and sheath extrusion process. The production process is relatively complicated, and it is difficult to control the production of cables. Currently, the most commonly collected The wire core is produced by extrusion molding. The wire core produced by extrusion molding has poor softness. After a long time of use, it is easy to be broken due to bending, which reduces the service life of the cable.
[0003] At present, in the production of cables, the processed wires are directly coated with insulating materials before the sheath is extruded. The insulation layer between the sleeves will fall, resulting in the leakage of the inner core of the cable, which will bring great hidden dangers to the safety of the cable.

Embodiment 1

[0021] The invention provides a cable production and processing technology, which specifically includes the following steps:

[0022] S1. Wire core monofilament drawing: use copper-aluminum rods with a ratio of 1:9 to heat to 40 degrees Celsius inside the heating equipment. Copper and aluminum rods are stretched synchronously into monofilaments with a diameter of 0.5;

[0023] S2. Core winding: after stretching, the temperature of the stretched monofilament is kept at 30°C, and more than 2 monofilaments are twisted in a non-backward manner through a stranding machine, and injected at the junction of the monofilament twisting while twisting The copper-aluminum structure is bonded with glue containing copper powder to make a wire core. The glue containing copper powder structure has a certain conductive effect. While the glue is used to fix the monofilaments, the conductivity of the twisted monofilaments is maintained. ;

[0029] The invention provides a cable production and processing technology, which specifically includes the following steps:

[0030] S1. Wire core monofilament drawing: use a copper-aluminum rod with a ratio of 1:9 to heat it to 60 degrees Celsius inside the heating equipment. Copper and aluminum rods are stretched synchronously into monofilaments with a diameter of 0.5;

[0031] S2. Core winding: after stretching, the temperature of the stretched monofilament is kept at 60°C, and more than 2 monofilaments are twisted in a non-backward manner through a stranding machine, and injected at the junction of the monofilament twisting while twisting The copper-aluminum structure is bonded with glue containing copper powder to make a wire core.

Embodiment 3

[0037] The invention provides a cable production and processing technology, which specifically includes the following steps:

[0038] S1. Wire core monofilament drawing: use a copper-aluminum rod with a ratio of 1:9 to heat it to 50 degrees Celsius inside the heating equipment. Copper and aluminum rods are stretched synchronously into monofilaments with a diameter of 0.5mm;

[0039] S2. Core winding: after stretching, the temperature of the stretched monofilament is kept at 50°C, and more than 2 monofilaments are twisted in a non-backward manner through a stranding machine, so that the twisted monofilaments are twisted in an S structure. At the same time as twisting, the glue containing copper powder is injected into the copper-aluminum structure to make the core. The glue containing the copper powder structure has a certain conductive effect, and the glue is used to fix the wires between the monofilaments. At the same time, maintain the conductivity after twisting between mo...

Abstract

The invention discloses a cable production and processing technology. The technology includes, heating a copper-aluminum rod to 50 DEG C; drawing monofilaments in annealing at 450 DEG C; injecting glue containing copper powder when the monofilaments are twisted; fixing the twisted monofilaments through the glue; maintaining the conductivity between the monofilaments through the copper powder; heating the twisted and fixed monofilaments to 35 DEG C; passing the monofilaments through an insulating glue; adding silica gel into the insulating glue to improve the toughness of the insulating glue for protecting the outside of a wire core; reheating the wire core coated with the insulating glue to 10 DEG C to extrude a sheath, so as to enable the insulating glue outside the wire core to generatea certain viscosity after being heated to enable the extruded sheath to coat the outside of the wire core through the viscosity of the insulating glue; and thermoforming and shaping the wire core coated with the extruded sheath through a heating chamber with the internal temperature of 25 DEG C, so as to enable the extruded sheath to shrink after being heated and tightly adhere to the outside of the wire core. The service life of the cable is prolonged, the damage of the insulation layer with the breakage of the extruded sheath outside the wire line is avoided, so that the use safety of the cable is not affected.
