Multi-strand special conductor twisting and back-twisting cage wire stranding machine

Abstract

The invention discloses a multi-strand special conductor twisting and back-twisting cage wire stranding machine, belonging to the field of a cage wire stranding machine. The cage stranding machine ofthe invention comprises a power transmission mechanism, a conductor twisting mechanism, a conductor winding mechanism and a conductor take-up mechanism, wherein the power transmission mechanism is connected with the conductor twisting mechanism and the conductor winding mechanism, and a twisted conductor formed by the unwinding of the conductor twisting mechanism is coiled and winded in the conductor winding mechanism after being shaped by the conductor take-up mechanism. A multi-stage back-twisting gear set is utilized to always ensure that unwinding positions are fixed, and an infinitely variable transmission is cooperated to drive coiling and shaping of the conductor. In this way, the wire stranding machine effectively avoids problems of a broken stranded conductor, strand jumping, twisting, roundness of the cross section of the conductor and the like caused by unwinding instability of a conventional cage wire stranding machine, can accurately control the roundness of the cross section, the pitch and the stranding direction of the twisted conductor, is easy to operate, is high in safety factor, and is suitable for large-scale and high-efficiency stranding production of special conductors.

Description

technical field [0001] The invention relates to a cage type wire stranding machine, more specifically, relates to a cage type wire stranding machine for twisting and untwisting multi-strand special conductors. Background technique [0002] With the continuous development of my country's new generation of information technology industry, aerospace, electronic devices and medical devices, the inner conductors for signal transmission wires and cables must maintain good performance in terms of signal transmission performance, mechanical properties, oxidation resistance and corrosion resistance, and harsh environments. Conductor stability etc. present new challenges. The inner conductor material for wire and cable signal transmission has developed from general-purpose bare copper wire to subsequent coated copper wire (silver-plated, nickel-plated and tin-plated), as well as the multi-strand coated high-strength, high-conductivity copper alloy stranded wire that has been studied in...
