Two-way strand twisting device and center steel wire pay-off method

Abstract

The invention discloses a two-way strand twisting device. Flywheels are respectively arranged on a main machine frame and between rotating bearing mechanisms, cradle frames are respectively arranged on the main machine frame and between the flywheels, a pay-off assembly is arranged on each cradle frame, and a wire splitting guide wheel, a wire splitting pre-deformation assembly and a wire collecting mold are sequentially arranged on the cradle frames and at the side edge parts of the pay-off assembly. The center steel wire pay-off method comprises the following steps that a center steel wire can be sequentially wound on the left and right side flywheel lower edges, the left and right side flywheel centers and the right and left side flywheel upper edges, and a plurality of fine single wires are respectively concentrated onto the wire collecting mold by the wire splitting guide wheel through the wire splitting pre-deformation assembly. The two-way strand twisting device and the center steel wire pay-off method have the advantages that the two-way simultaneous strand twisting can be realized, the twice strand twisting can be completed when the flywheels rotate for one circle in each time, the automation degree is high, the energy consumption is low, the occupied area is small, the two-way strand twisting device and the center steel wire pay-off method are particularly applicable to the fast strand twisting of fine wires, and the work efficiency is also greatly improved.

Description

technical field [0001] The invention relates to a strand twisting machine for twisting a steel wire rope by single-pitch twisting, on-line internal stress elimination and the like, in particular to a strand twisting device and a wire-releasing method for the strand twisting machine. Background technique [0002] The stranding machine is a device that arranges multiple steel wires regularly and twists them into steel wire rope products in a balanced manner. At present, the old process equipment is still used for twisting steel wire ropes: single lay length multi-row tubular stranding machine to produce steel wire rope products, its speed: 2000r / min, output: 2000 twists / min. The production efficiency of this equipment is low, the unit output is only 1 / 5 of the double twisting machine, and the working noise is large, the energy consumption is large, the safety performance is poor, and the equipment occupies a large area. It is generally suitable for the production of thick-size...
