Description

Technical Field

[0002] Wire cutting equipment is a special machine tool that realizes precision processing of materials through the principle of electric spark discharge corrosion. Wire cutting equipment usually needs to thread the wire during cutting. The wire is passed through the pre-punched hole in the workpiece, and then passes through the lower eye mold, the lower conductive block and the wire storage drum to complete the wire threading. Existing equipment usually uses a motor to drive the wire, and the wire is assisted by a guide sleeve to enter the wire threading hole of the workpiece from the upper eye mold. The air nozzle above the wire threading hole sprays air to assist wire feeding. The wire continues to move after passing through the lower guide wheel and the conductive block, and moves to the wire storage drum position and is fixed by the wire pressing block. At this time, after the wire storage drum rotates a preset number of circles, the wire runs smoothly and the wire threading is completed. Since the wire is transported by the air flow and the motor, when passing the guide wheel under the workpiece, if the wire is not in a straight state, it is easy for the wire to bend and become blocked or the wire is stuck in the gap of the side wall of the lower guide wheel, resulting in wire threading failure.

[0004] However, the technical solution of this patent has the following problems: This patent cannot ensure that the wire can be normally stuck on the lower guide wheel for wire transportation when the wire bends after passing through the workpiece, and cannot quickly change the tube to perform perforations of different sizes and transport wires of different thicknesses.
