This wire twisting machine is used to twist armature lead wires. It adopts a horizontal fixture structure, consisting of twisting part, front insertion protection device, workpiece fixing device, workpiece tightening device, workpiece ejection device, operation part and program control part. The adoption of protection device ensures no breakdown of the root of copper wire and guarantees the quality of final formed hairpins.
