The wire cut electrical discharge machine capable of reciprocating wire feeding (including middle wire feeding) is a unique electrical discharge machining machine type in China, can machine various precision dies, can machine metal workpieces with large thickness, taper, upper and lower special shapes, can cut inner holes of dozens of wires by using electrode wires, is one of the most widely applied machines in China at present, and has the advantage that the machine cannot be replaced in the field of die manufacturing. However, the reciprocating wire-cut electric spark wire cutting machine tool has no foreign one-way wire-cutting (slow wire-cutting) machine type intellectualization, and particularly the slow wire-cutting machine has an automatic wire-feeding function. At present, the domestic round-trip wire feeding (including middle wire feeding) and wire discharging of an electric spark wire cutting machine are both manually operated, when the wire is fed, an operator stands in front of the machine firstly to enable a wire electrode to penetrate through a wire guide, then grips the wire electrode tightly with hands to bypass the wire electrode and clamp the wire electrode into a guide wheel groove, and then the wire electrode is conveyed to a wire storage cylinder of the machine and is pressed tightly by a screw. The operation is complicated and the yarn folding and the yarn breaking can be caused by slight error. Personnel injury caused by sudden rotation of a wire conveying and opening storage barrel due to circuit faults and misoperation can be prevented; the operator needs to stand behind the machine to loosen the screw by using a tool, one hand slowly rotates the wire storage barrel, and the other hand tightly grips the wire electrode and bypasses all guide wheels to a specified position (the operator still needs to move continuously during the process). The skillful, quality-guaranteed and quick operation can be realized only through a large amount of training.
