Comprehensive performance improvement of steel cord outer winding and twisting machine tool
To propose a renovation solution for improving comprehensive performance of steel cord external winding and twis-ting machine tool,adding dual torsion detection device(ATC),electromagnetic tension device,permanent magnet external winding head,virtual twisting device,constant tension winding and other components to original machine tool.The focus is on use of dual ATC,with the first ATC error prevention and online detection to prevent previous process from sacrificing quality for sake of production;The second ATC adjusts residual twisting of curtain in real time to improve product quality.After renovation,fluctuation range of wire tension is stable within±5 N;The twisting value of curtain can be produced on display screen as a fluctuation curve,allowing for real time adjustment and correction of deviations.The standard twisting target control value proportation of-1.5～+0.5 round accounts for 94％,increase 34％compared to before renovation.Eliminating parking and twisting inspection process,direct packing can be carried out,and personnel production efficiency can be increased 17％～24％,with significant economic benefits.
