Concentric type wire-stranding machine

Abstract

The invention relates to a concentric type wire-stranding machine. The concentric type wire-stranding machine comprises a bottom board (16), wherein the bottom board is connected with a set of machine frames (4) which are connected with a main shaft (3) in a matched mode, the rear end of the main shaft is connected with a branch wire storage reel (12), and the rear end of the main shaft is further connected with a motor (9) through a belt (10). The concentric type wire-stranding machine is characterized in that the main shaft is connected with a set of wire storage reel (2) in a matched mode, tension control devices are arranged on the main shaft respectively at an interval of two wire storage reels, and each tension control device is correspondingly matched with the wire storage reels on two sides of the corresponding tension control device. The concentric type wire-stranding machine has the advantages that the concentric type wire-stranding machine is of an integrated structure, the number of the circulation wire storage reels is reduced, and production cost is saved; rotation inertia is low, and rotating speed of the machine is increased; stranding and rewinding of a cable core can be conducted simultaneously, and operation time is saved; the machine can enable paying-off tension of a wire core to be stable and improve stranding quality of a cable.

Description

technical field [0001] The invention relates to a stranding machine, in particular to a concentric stranding machine. Background technique [0002] Stranding machine is a kind of soft / hard conductor wire (copper wire, enameled wire, tinned wire, copper-clad steel, copper-clad aluminum, etc.) and electronic wire (such as: power cord, earphone wire, telephone wire, etc.) , PVC wire, network wire, etc.) twisting mechanical equipment, so that multiple single conductors are twisted into one strand to meet the process requirements of wire. [0003] At present, wire and cable manufacturers are used for copper conductors or aluminum conductors without back-twisting twisting machines. The cable core is wound on the wire storage reel, and the cable core and the wire storage reel are installed on the twisted body together. When the stranded wire is produced, all the wire storage reels turn over around the center line of the twisted body together with the twisted body. This structure ...
