イヤーカット加工が途中で停止するなどの課題があった
。Conventional wire-cut electrical discharge machines are configured as shown below, so the wires are fed into the collection box while still being connected in a straight line, making it inefficient to store the wires, and also causing wires to protrude from the opening and connect to the main body of the machine. There were issues such as short-circuiting of the wires and the wire cutting process stopping midway through.
この発明は上記のような課題を解消するためになされた

されている。Next, the operation will be explained. Opening (3) of collection box (1)
) A pair of rollers (9) H rotated by a drive device (not shown) are provided nearby, and a wire guide plate αυ is attached below these rollers so that the direction of curvature is in the direction of the roller 00 provided with protrusions. ing. The electric discharge machined wire (4) that is continuously fed is passed through a pair of rollers (9)
(It) When the wire (4) is passed through the crimping part and is fed out by rotation, the elastic member roller αQ and the small diameter roller (9) are rotated in the crimped state, and the wire (4) to be sent out is moved to the crimping part. It is bent into a curved shape in the direction of the small-diameter roller (9) and stored in the collection box (1) while being continuously wound in a spiral manner to a predetermined diameter. The diameter of the spiral wire (4) is larger than the width of the opening (3) of the collection box (1).
〔発明の効果〕。〔Effect of the invention〕.
以上のようにこの発明によれば、放電加工済のワイヤー
を圧着して送り出す一対のローラにより、上記ワイヤー
を一方向に屈曲させて回収箱の開口部幅より大径の螺線

が向上できる効果がある。As described above, according to the present invention, a pair of rollers that pressure-bonds and sends out a wire that has been subjected to electrical discharge machining bends the wire in one direction and forms it into a spiral shape having a diameter larger than the width of the opening of the collection box. This configuration has the effect of improving wire storage efficiency.
