AI Technical Summary
In existing coaxial composite wire manufacturing technologies, the composite quality control of the core material and the sheath is independent and passive, resulting in core material eccentricity and uneven sheath thickness, which affects the conductivity reliability and structural consistency of the wire.
By preheating and monitoring the carbon fiber core material in real time, and using an electrode ring device for Joule heating and air pressure regulation, thermal-pressure coupling control is achieved, dynamically correcting the core material eccentricity and maintaining its centering. At the same time, segmented progressive cooling and online monitoring of outer diameter and resistance are adopted to ensure consistent sheath shaping.
This technology enables coordinated control of the temperature field and core material position during coaxial extrusion, resulting in structurally stable coaxial coated wires and improving the wire's conductivity reliability and structural consistency.
