Stranding device for prestressed steel strand production and processing

Abstract

The invention discloses a stranding device for prestressed steel strand production and processing. The stranding device for prestressed steel strand production and processing comprises a base, a vertical plate, a pull rope winding wheel, a stranding disc, a sliding rod, a third stepping motor, a guide rod, a cylindrical cam, a U-shaped mounting plate, a supporting plate, a second driving gear, a driven gear ring, a second stepping motor, a circular-truncated-cone-shaped pressing base, a guide plate, an upper arc-shaped base, a steel strand winding barrel, a limiting pin, a cross-shaped rod, a lower arc-shaped base, a pull rope, a supporting rod, a fixed pulley, a double-shaft motor, a driven gear, a first driving gear, a mounting disc, a rotating disc, a clamping block, a first stepping motor, a limiting cylinder, a left-right rotating lead screw, a driving seat, a connecting rod, a limiting column, a mounting groove and a rotating roller. According to the stranding device for prestressed steel strand production and processing provided by the invention, through mutual cooperation of the stranding disc, the cylindrical cam, the sliding rod, the circular-truncated-cone-shaped pressing base, the guide rod, the guide plate and the gear ring, the stranding position of a steel strand can be better and repeatedly extruded when the steel strand is stranded, so that the stranding compactness of the steel strand is guaranteed, and the stranding efficiency is greatly improved.

Description

technical field [0001] The invention relates to a stranding device, in particular to a stranding device for production and processing of prestressed steel strands, and belongs to the technical field of prestressed steel strand production. Background technique [0002] The prestressed steel strand is a stranded steel cable composed of multiple high-strength steel wires, and has been treated with stress relief. It is suitable for prestressed concrete or similar purposes. In most post-tensioned prestressed and pre-tensioned prestressed projects, smooth steel Stranded wire is the most widely used prestressed steel material. Die-drawn steel strand is mainly used in lifting engineering, but also in projects such as nuclear power. [0003] During the stranding process of the existing stranding device, due to the rotating stranding, it is easy to cause the strands to be not tightly twisted, so that the twisted strands are easy to loose, and the strands The installation and disassem...

AI Technical Summary

Problems solved by technology

[0003] During the stranding process of the existing stranding device, due to the rotating stranding, it is easy to cause the strands to be not tightly twisted, so that the twisted strands are easy to loose, and the strands The installation and disassembly of the wire reel is not convenient and efficient, and it is cumbersome to operate, which greatly improves the work intensity of the staff and the use effect is poor
