Description

A prestressed steel strand winding machine

technical field

The utility model relates to the technical field of steel strand production equipment, in particular to a prestressed steel strand winding machine.

Background technique

Prestressed steel strand is a stranded steel cable consisting of 2, 3, 7 or 19 high-strength steel wires, and has been treated with stress relief (stabilization treatment), suitable for prestressed concrete or similar applications. The manufacturing process is divided into monofilament manufacturing and stranded wire manufacturing. (Cold) wire drawing technology is used to make monofilament. According to different products, the material can be high carbon steel wire rod, stainless steel wire rod or medium and low carbon steel wire rod. Zinc shall be electroplated or hot-dipped on the monofilament. In the strand manufacturing process, a stranding machine is used to twist a plurality of steel wires into a product, and finally the twisted steel strands are wound on a reel.

With the innovation of industrial production technology, automatic production technology is applied to various fields, including the strand manufacturing process of steel strand. In the prior art, the automatic winding equipment located at the end of the production line during the stranded wire manufacturing process has poor operation stability, and the wound wire coils are not meticulous and easily scattered.

The utility model drives the active rotating shaft to rotate through the driving device, and the active rotating shaft drives the reel to rotate, thereby realizing the automatic coiling of the steel strand on the reel. Due to the function of the wire straightener, the relative position of the steel strand and the reel can be adjusted in sequence during the winding process, so that the steel strand can be coiled on the reel neatly. The wire unwinder moves back and forth to make the steel strands tightly wound. The utility model makes the power output of the driving rotating shaft to the cable arranger through the gear, the pulley and the belt, so that it shares a driving device, and completes the differential speed adjustment of the rotating speed through the gear and the pulley.

A strand clamping device is installed in front of the wire unwinder (that is, upstream), which can prevent the steel strand upstream of the wire unwinder from shaking freely and play a role in stabilizing the steel strand, and the strand clamping device can hold the steel strand It plays a clamping role and forms resistance, so that a section of steel strand between the strand clamping device and the reel is always in a tight state, and will not be too loose, so that the coil on the reel is tight and stable, and does not will be scattered.

The three clamping rods can prevent the steel strands from dragging the ground. The clamping force and resistance gradually decrease from bottom to top. With the different degrees of relaxation of the steel strands, the strand clamping device clamps the position of the steel strands. Certain changes will also occur to achieve the function of self-adjustment.
