Wire electrode supplying apparatus for wire electric discharge machine
First Claim
1. A wire electrode supplying apparatus for a wire electric discharge machine, comprising:
- a feeding section for feeding a wire electrode;
a feeding-side guide section through which the wire electrode fed from said feeding section is passed through and which is adapted to constrain the direction of movement of the wire electrode;
a receiving-side guide section for guiding the wire electrode, said receiving-side guide section being disposed in such a manner as to oppose said feeding-side guide section, and the wire electrode fed from said feeding-side guide section being passed through said receiving-side guide section;
a feeding amount detecting means for detecting an amount of the wire electrode fed from said feeding section;
a jet nozzle for constraining the direction of movement, toward said receiving-side guide section, of the wire electrode fed from said feeding-side guide section, as a jet of working fluid flows toward said receiving-side guide section; and
control means for controlling the supply of the jet to said jet nozzle in correspondence with the detected result of said feeding amount detecting means.

Abstract
A wire electrode supplying apparatus for a wire electric discharge machine to effect the machining of a workpiece by inserting a wire electrode through the workpiece and allowing electric discharge to take place between the workpiece and the wire electrode. In this apparatus, a wire electrode feeding section is provided for inserting the wire electrode through the workpiece, as well as a feeding-side guide section and a receiving-side guide section are provided with the workpiece placed therebetween for the positioning of the wire electrode. The wire electrode is formed of a small-diameter wire, and the feeding-side guide section and the receiving side guide section are respectively provided with small openings for constraining the direction of its movement. The passage of the wire electrode through the small openings is aided by reducing the speed of feeding the wire electrode when the wire electrode passes through the small openings. A vertically movable jet nozzle is provided for allowing a working fluid to be jetted from the vicinity of the feeding-side guide section toward the receiving-side guide section so that the wire electrode after passing through the feeding-side guide section heads toward the receiving-side guide section. By starting the jetting of the working fluid after passing through the jet nozzle, the wire electrode is guided positively.
