AI Technical Summary
Traditional tire bead wire drawing processes suffer from environmental pollution, low production efficiency, unstable quality, and high breakage rates. In particular, the lack of precise quality testing methods and poor process coordination lead to uneven cold drawing and inconsistent wire properties.
By analyzing the cross-sectional perimeter and circularity fluctuation of the steel wire rope after the first cold drawing, and verifying it using the sliding window method and Pearson correlation coefficient, the uniformity of the cold drawing of the steel wire is determined. Furthermore, through multi-pass independent servo frequency conversion control and PLC closed-loop speed measurement and control system, precise matching and real-time correction of the linear speed are achieved.
It effectively solves the problem of uneven cold drawing, reduces production losses, improves continuous production efficiency and product quality stability, and ensures the overall mechanical properties of the wire rope.
