Straightening production process for load-bearing detection cable

Abstract

The invention relates to the technical field of cable production processes, and discloses a load-bearing detection cable straightening production process, which comprises the following steps that 1) acopper stranded wire is moved into core wire production equipment, the production equipment is kept sealed, air in the equipment is completely exhausted, nitrogen is introduced, and the copper stranded wire is pulled from middle to outside through a machine to be changed into the copper stranded wire with the proper thickness; the invention discloses a straightening production process for a load-bearing detection cable. The method comprises the following steps: step 2) immigration of fine copper wires; straightening and processing are carried out in the straightening equipment; the straightening equipment is used for processing the thickness and the uniformity of the fine copper wires; the overall uniformity of the thin copper wires is ensured; meanwhile, wire drawing oil is sprayed to the equipment at the outlet of the straightening equipment, so that a wire drawing oil protection layer is damaged by the straightening equipment, copper is oxidized, the overall uniformity of internalcopper wires can be guaranteed, the phenomenon that the service life of the equipment is shortened due to local heating is avoided, the conductive efficiency of the cable is effectively improved, andthe service life of the cable is effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of cable production technology, in particular to a production process for straightening a load-bearing detection cable. Background technique [0002] The flexibility of the wire and cable, that is, the bendability, depends on the elasticity of the conductive wire and the diameter of a single metal wire, as well as the pitch of the helical winding. Since the core of the conductive wire needs to use a specific metal wire, the elasticity of the conductive wire It is not variable, but the pitch is limited relative to the diameter of the wire and cable. Therefore, the biggest variable factor is the diameter of a single metal wire. The smaller the diameter, the smaller the bendable radius and the better the bendability. [0003] The cable is usually a rope-like cable made of several or several groups of wires, at least two in each group. Each group of wires is insulated from each other and is often twisted around ...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a production process for straightening load-bearing detection cables, which has the advantages of simple procedures and long service life, and solves the problem that the cable production process in the prior art is very complicated and the synthesis process conditions are relatively strict. The cost of cables is high, and there is no straightening process in the production process of existing cables, which may lead to the problem that the cable thickness is different and the service life of the cables is reduced.
