Description

Technical Field

[0001] The invention relates to the technical field of steel cord detection equipment, and in particular to a steel cord bow height torsion straightness detection device. Background Art

[0002] Steel cord is the most difficult product to produce among metal products. It is mainly used in the skeleton of passenger car tires, light truck tires, heavy truck tires, construction machinery tires, aircraft tires and other rubber products. Usually, the steel cord is wound on the I-shaped wheel, and several hundred meters of steel cord will be wound on one I-shaped wheel.

[0003] Bow height, residual torsion and straightness are three important indicators of steel cord. ① The bow height of steel cord is an indicator of the degree of bending of steel cord in its natural state. After being wound on the I-shaped wheel for a period of time, the steel cord is bent and deformed, and the straightness is not enough. At present, the bow height requirement of most steel cords is not more than 20mm. Directly using steel cords that do not meet the bow height requirements for production will lead to internal stress concentration after the finished product is produced. ② The residual torsion of steel cord will affect the performance of the finished product produced by the steel cord. Twisting and curling will generate stress. Excessive torsion will cause internal stress concentration in rubber products, making rubber products easily damaged. Therefore, before using steel cords in production, it is necessary to detect the residual torsion of steel cords to reduce the impact of excessive torsion on rubber products. ③ In addition, if the straightness of steel cords is not good, it is easy to cause unevenness of tire cords, which will cause the cords to warp when they are cut, affecting the docking of cords.

[0004] In the prior art, the bow height, residual torsion and straightness detection of steel cords are all performed by separate devices, resulting in low detection efficiency. Summary of the invention
