Description

Technical Field

[0001] This utility model relates to an auxiliary tool for manufacturing steel reinforcing strips, and more specifically, to a wire splitting device for reinforcing strips. Background Technology

[0002] Plastic composite pipe steel fiber (steel cord) reinforcing tape is composed of an appropriate number of parallel steel fibers (steel cords) bonded to hot melt adhesive. The spacing and tension uniformity of the steel fibers (steel cords) directly affect the tensile strength of the reinforcing tape. Conventional steel fiber (steel cord) splitting methods include comb-tooth and perforated plate methods. For the comb-tooth method, such as... Figure 5 As shown, the comb teeth should have high hardness and wear resistance, as well as a certain degree of toughness and vibration resistance. If the comb teeth are too hardened after heat treatment, they are prone to breakage; if they are too soft, they are not wear-resistant and easily deformed, requiring frequent replacement and thus increasing costs. For the perforated plate method, such as... Figure 6 As shown, the holes are usually arranged in multiple rows, which makes threading the wires troublesome. The gaps between the holes are large, and the steel fibers (steel cords) are not parallel when guided. The tension is large in the upper and lower rows and on both sides, while the tension in the middle is small. The tension between each fiber is inconsistent, which affects the tensile strength of the reinforcing strip and reduces the material utilization rate. Utility Model Content
