Large-diameter triangular strand steel wire rope pre-deformer

Abstract

The invention discloses a large-diameter triangular strand steel wire rope pre-deformer which comprises a main shaft. A front disc, a middle disc and a rear disc are arranged on the main shaft in a sleeving mode; at least two of the front disc, the middle disc and the rear disc can slide relative to the main shaft so as to adjust the distance between rollers; the front disc, the middle disc and the rear disc are each provided with a plurality of positioning rollers used for shaping the triangular strands in the circumferential direction; and each positioning roller comprises a shaping hole and an adjusting bolt used for adjusting the size of the shaping hole, so that the sectional area tolerance of the triangular strands can be controlled conveniently. At least two of the front disc, the middle disc or the rear disc slide relative to the main shaft to adjust the distance between the rollers, so that the screw pitch of a steel wire rope can be adjusted; and the sectional area tolerance of a formed strand can be adjusted through the adjusting bolt, so that the constant form and location tolerance of the large-diameter triangular strand steel wire is effectively controlled, and the production quality is improved.

Description

technical field [0001] The invention relates to the technical field of steel wire rope processing, in particular to a pre-deformer for a thick-diameter triangular-strand steel wire rope. Background technique [0002] In the production of thick-diameter triangular-strand steel wire rope, due to the large diameter, the quality control error of the conventional twisting process is relatively large, which is likely to cause problems such as loose wire rope, air bubbles and uneven tension, which will affect product quality. [0003] To sum up, how to improve the production quality of the large-diameter triangular-strand steel wire rope is an urgent problem to be solved by those skilled in the art. Contents of the invention [0004] In view of this, the purpose of the present invention is to provide a pre-deformer for thick-diameter triangular-strand steel wire rope, which can adjust the pitch of the steel wire rope and the tolerance of the forming strand section, and realize ef...
