AI Technical Summary
Existing wire straightening mechanisms do not facilitate the unwinding of bent wires before straightening them, which may cause the wires to become entangled, experience excessive resistance, or break due to stress concentration caused by excessive bending during unwinding.
A gas-shielded welding wire clamping mechanism with straightening function was designed. By using the guide component and the straightening component together, the welding wire is guided, positioned and clamped and fixed by the motor-driven rotating rod and belt drive, so as to prevent the welding wire from being misaligned and excessively bent.
This ensures that the welding wire is smoothly positioned and fixed during the unwinding process, avoiding breakage and curling, thus improving the stability and reliability of welding.
