Steel strand tightening and taking-up device

Abstract

The invention discloses a steel strand tightening and take-up device, and relates to the technical field of steel strand winding. A tightening unit comprises a base, wherein two strand inlet rollers are rotationally arranged on one side edge of the base, a wedge plate is fixedly arranged on the other side edge of the base, double clamping plates are arranged in the base in a lifting mode, a strandwinding roller and a strand outlet roller are rotationally arranged in the double clamping plates, and the strand winding roller is arranged in a sliding movable seat; and the take-up unit comprisesa bottom plate, wherein a storage rack is arranged on the bottom plate in a reciprocating sliding mode, clamping air cylinders are fixedly arranged at the two ends of the storage rack, and a winding drum is clamped between the two clamping air cylinders. A steel strand sequentially penetrates through the strand inlet rollers, the strand winding roller and the strand outlet roller at preset positions, travels a snake-shaped route, and is tensioned by preset tension and then wound on the peripheral side of the winding drum, and when the winding drum drives the steel strand to be wound layer by layer, the double clamping plates rise gradually and are pushed by the wedge plate, so that the penetrating and winding stroke of the steel strand in the base is reduced, the steel strand can be prevented from being excessively tensioned or loosened while the original tensioning force is kept, and the stability and neatness of steel strand winding are ensured.

Description

Technical field [0001] The invention relates to the technical field of steel strand winding, in particular to a wire take-up device for steel strand. Background technique [0002] Stranded wire is a steel product made up of multiple steel wires stranded. It is mainly used in bridge engineering, building construction, water conservancy construction, energy engineering and geotechnical engineering. In the production of steel strands, small steel wires are twisted into a whole steel wire. The specific production line involves the production processes of washing, blowing, oiling, gluing and hinged. Because the steel strands are linear products, Therefore, in the process of mechanized production line, it is necessary to ensure the stability of the steel strand during the transmission process. [0003] In response to the above-mentioned problems, the Chinese Patent Publication No. CN209081129U proposes a steel strand winding device, which includes a base. One end of the upper surface of...

AI Technical Summary

Problems solved by technology

[0004] The newly formed steel strand is in a relatively unstable state after stretching, stranding, and shaping. At this time, loose winding will easily lead to loose stranding of the steel wire, and excessive winding will easily cause the toughness of the steel wire to become weak, excessive relaxation and excessive tension. Tension will affect the actual use later

Therefore, a stable and stable winding speed is required, but the existing winding machine, the wire feeding speed and the winding speed are uniform at the beginning, but as the winding diameter of the steel strand increases, the winding speed is accelerated, and the winding force is very easy to appear. Uncontrollable conditions, which will affect the quality of steel strands in severe cases
