Abstract

The invention discloses a manufacturing process of a steel-core aluminium stranded wire, and the manufacturing process comprises the following steps: painting and printing; measuring the depth of an aluminium tube and marking on a steel-core aluminium stranded wire; performing secondary treatment after crimping; and performing secondary treatment on burrs, flash or bending after crimping, after treatment, checking whether a product is qualified, if a treatment result cannot be qualified, performing crimping again. The manufacturing process also comprises the following steps: penetrating a tube; placing the right end of a left side steel-core aluminium stranded wire to be crimped into the aluminium tube and positioning, the right side steel-core aluminium stranded wire being located at thetube orifice of the aluminium tube; performing intertwining; gradually stretching the left end of the right side steel-core aluminium stranded wire into the aluminium tube; gas generated by a piston in a cylinder block being pushed by a support plate being used for clearing the residue and dust in the aluminium tube; a first motor driving the right side steel-core aluminium stranded wire through aT-shaped plate to be wound on the left side steel-core aluminium stranded wire in the aluminium tube; crimping; and utilizing a hydraulic press to crimp the aluminium tube, i.e., realizing the hydraulic pressure welding of the steel-core aluminium stranded wire. The scheme mainly solves the problem that at present a steel-core aluminium stranded wire is easy to slip off an aluminium tube after pressure welding.

Description

technical field [0001] The invention relates to the technical field of crimping structures for power transmission lines, in particular to a crimping structure for steel-cored aluminum stranded wires. Background technique [0002] Steel-cored aluminum stranded wire refers to a reinforced wire with single-layer or multi-layer aluminum strands twisted outside the galvanized steel core wire, which is mainly used in the power and transmission line industry. At present, during the use of the steel-cored aluminum stranded wire, the steel-cored aluminum stranded wire will be cut according to the needs to meet the applicable standards, and the cut-out steel-cored aluminum stranded wire is mainly disposed of by discarding, resulting in waste of resources ; In the actual operation process, since the cut aluminum-reinforced steel-reinforced wire is still usable, multiple segments of aluminum-reinforced steel-reinforced wire can be connected by hydraulic crimping to realize reuse.
