Description

Technical Field

[0001] This utility model relates to the field of steel strand production technology, specifically to a wire drawing device for steel strand production that is easy to fix. Background Technology

[0002] Steel strand is a steel product made of multiple steel wires twisted together. The manufacturing process is divided into single-wire manufacturing and strand manufacturing. Single-wire manufacturing uses (cold) drawing technology, and the material can be high-carbon steel wire rod, stainless steel wire rod, or medium-low carbon steel wire rod, depending on the product. If galvanizing is required, electroplating or hot-dip galvanizing should be performed on the single wire. During strand manufacturing, a stranding machine is used to twist multiple steel wires into a product. Prestressed steel strand also requires continuous stabilization treatment after forming. Before stranding, steel strands need to be drawn, and drawing equipment is a machine that draws wire rods into fine iron wires. Patent CN221620374U discloses a drawing device for steel strand production. During drawing, the steel strand passes from the feeding end around a guide pulley, then around a wire-passing pulley, and then through a drawing motor inside a housing for drawing. It then passes around a drawing wheel and a guide wheel, and finally through a cooling box to complete the drawing process. During drawing, the drawing motor drives the drawing operation through a transmission mechanism. If the feeding end gets stuck and cannot release the wire normally, the drawing motor... The wire drawing motor continues to run, pulling the steel wire and generating a backward pulling force on the wire guide pulley. This causes the rotating plate to flip backward, thus disconnecting the contact switch and stopping the wire drawing motor. This prevents wire breakage due to wire jamming at the inlet end. However, it is inconvenient to wind the wire before drawing, as winding is laborious and it is also inconvenient to adjust the wire drawing strength. Therefore, a wire drawing device for steel strand production that is easy to fix, allows for convenient winding, easy adjustment of wire drawing strength, and avoids slippage when the wire breaks.

The top of the drawing box is provided with a fixing and pressing mechanism adapted to the multiple lifting guide rollers. It also includes a lifting adjustment mechanism that can simultaneously lift the four sets of lifting guide rollers as a whole. Guide blocks are provided on both sides of the two side guide rollers. The two guide blocks are fixedly connected to the drawing box.

[0007] Preferably, the fixing and pressing mechanism includes a fixing pressure bar, which is suspended on the inner top of the wire drawing box by a drive cylinder, and a guide rod that slides vertically with the wire drawing box is fixedly installed on the top of the fixing pressure bar.

[0011] (III) Beneficial Effects

[0012] Compared with the prior art, this utility model provides a wire drawing device for steel strand production that is easy to fix, and has the following beneficial effects:

[0013] This easy-to-fix steel strand production wire drawing device features a row of wire drawing guide rollers and a set of lifting guide rollers that can move up and down through the wire drawing guide rollers. The lifting guide rollers can be easily moved to a position below the wire drawing guide rollers, and then the steel wire is passed between the wire drawing guide rollers and the lifting guide rollers. A lifting adjustment mechanism easily stretches the lifting guide rollers, thus raising the steel wire. This allows the wire drawing drive mechanism to rotate the two wire drawing rollers, drawing the wire that passes through from both sides. If a wire breaks, a fixing and clamping mechanism can be used to press down from the top and cooperate with the lifting guide rollers to fix the wire, preventing slippage when the wire breaks. The wire drawing intensity can also be adjusted by adjusting the height of the lifting guide rollers. This easy-to-fix steel strand production wire drawing device facilitates winding, allows for easy adjustment of the wire drawing intensity, and prevents slippage when the wire breaks.
