Anti-breaking double-twisting machine

Abstract

The invention relates to the field of machining, in particular to an anti-breaking double-twisting machine which is provided with a rotary back-twisting device, a cradle is connected to a rack through a rotary shaft, and a pay-off spool is connected with the rotary shaft penetrating through the cradle, so that torsion stress of monofilaments in the twisting process is eliminated through rotary back-twisting, torsion deformation of steel wires is reduced, and the stress change of the steel wire is avoided; meanwhile, a tension control device is arranged, tension is adjusted to be within a constant range, pay-off tension is balanced, wire breakage caused by uneven tension is avoided, and the problems that when a traditional double-twisting machine is used for machining, due to abrasion between the traditional double-twisting machine and a wire coil and torsional deformation of the steel wire, the stress and tension of the steel wire are greatly changed, and wire breakage is caused and in the whole production process, the change of stress and tension is not fed back, further the quality of a product is seriously influenced, and the steel wire is very easy to break in the twisting process are solved.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to an anti-broken double-twisting machine. Background technique [0002] Twisting strand is an essential process in steel wire rope processing, and double twisting machine is a processing machine for twisting strands. The efficiency of steel wire rope produced by double twisting machine is more than 3 times that of tubular stranding machine. The tension is easier to control than the tubular stranding machine, and the twisting quality is better. In developed countries, the double twisting machine is mainly used to twist the wire to contact the steel wire rope strand. important path to progress. Due to the strict quality requirements for the steel wire used in the double-twisting machine, if the steel wire is produced with a double-twisting machine, if there are small defects in the steel wire, such as inclusions, nicks, internal cracks, scratches, and uneven diameters, it will c...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to make up for the defects of the prior art, and to provide an anti-broken double-twisting machine to solve the problem that the stress and tension of the steel wire will occur due to the wear and tear of the wire reel and the torsional deformation of the steel wire during the processing of the current double-twisting machine. Relatively large changes, and there is no feedback on the changes in stress and tension during the entire production process, which seriously affects the quality of the product, resulting in the steel wire being very easy to break during the twisting process
