Conductive wire fixed-length cutting machining device and using method

The invention provides a conductive wire fixed-length cutting machining device and a using method, and belongs to the technical field of conductive wire cutting. The conductive wire fixed-length cutting machining device comprises a cutting table plate, a wire directional guide roller set is arranged on the cutting table plate, an actuating part vertically and linearly moving is arranged at the top of the cutting table plate, and a connecting rod is arranged at the bottom of the actuating part; and the end part of the connecting rod is hinged with a U-shaped limiting end head for limiting the wire rod inside. According to the S-shaped stretching device, the U-shaped limiting end heads at the end parts of the left connecting rod and the right connecting rod move in opposite directions, so that the wires are pulled, the continuous S-shaped arrangement of the wires is further realized, the actuating part moves downwards, and the length of the wires is fixed according to the moving distance; therefore, the transve
