Description

Technical Field

[0001] This utility model relates to the field of steel-cored aluminum stranded wire technology, specifically a steel-cored aluminum stranded wire straightening device. Background Technology

[0002] Aluminum stranded wire is a bare conductor. In China, aluminum-clad steel stranded wire is commonly used as the conductor. The steel core mainly serves to increase strength, while the aluminum stranded wire mainly transmits electrical energy. The cross-sectional area of ​​the conductor varies depending on the voltage. During transportation, aluminum stranded wire needs to be wound into rollers. When laying and installing aluminum stranded wire, it requires straightening, thus necessitating a straightening device. A search revealed that patent CN221109716U discloses a steel-cored aluminum stranded wire straightening device. This device uses two rows of parallel drive straightening wheels and adjusting straightening wheels to straighten bent aluminum stranded wire through compression. Theoretically, the driving straightening roller can drive the aluminum strand, thus facilitating continuous straightening of the aluminum strand by the device. The adjusting straightening roller can adjust the force during the extrusion of the aluminum strand. However, it also needs to have a traction function while straightening, resulting in high straightening energy consumption. In addition, the driving straightening roller and the adjusting straightening roller have point contact with the aluminum strand, resulting in a short straightening time at each point of the aluminum strand, thus the straightening effect needs to be improved. Therefore, a steel-cored aluminum strand straightening device is designed to facilitate line contact straightening, increase the straightening time at each point of the aluminum strand, and ensure the straightening effect of the aluminum strand.

[0014] Beneficial effects:

[0015] This steel-cored aluminum strand straightening device, through two guide tubes and a straightening cylinder, facilitates the steel-cored aluminum strand to pass through the straightening cylinder and between two straightening rollers. The overall angle of the two straightening rollers can be adjusted via a rotational adjustment structure, ensuring line contact between the rollers and the steel-cored aluminum strand. By pulling the steel-cored aluminum strand on one side, it is guided by the two straightening rollers. During this process, the steel-cored aluminum strand drives the straightening rollers to rotate, and the rollers then react on the strand, straightening it. Guide rollers located on both sides of the guide tubes within the straightening cylinder facilitate the straightening of the steel-cored aluminum strand, improving the smoothness of the straightening process. This allows the steel-cored aluminum strand to enter from one side and exit straight from the other. This straightening device facilitates line contact straightening, increases the straightening time at each point on the aluminum strand, and ensures the straightening effect.
