摘要: An automatic wire connecting apparatus of a wire cut electric discharge machine performs automatic connection of a wire electrode smoothly and reliably. A wire processing unit (90) integrally rotatably coupled to a rotating shaft (61) of a pneumatic motor (60) has a nozzle forming portion (12) which defines a slit (S) that allows a wire electrode (W) to pass therethrough when it is opened, and which defines a nozzle hole (125) capable of fitting with an upper wire guide (12) when it is closed, and is selectively positioned at a wire insertion position or an escape position by a rotary stopper (150). When the wire electrode is broken, the wire processing unit is rotated from the escape position to the wire insertion position by a motor, and thereafter, the nozzle hole forming portion is closed, thereby holding the wire electrode guided through the slit during a rotating operation in the nozzle hole. When a working fluid is supplied from the upper wire guide to the nozzle hole, the wire electrode is fed while being restricted by the working fluid sprayed toward a workpiece (P), and is then automatically connected.

摘要: A wire feed mechanism of a wire electric discharge machine, which rewinds a wire electrode (P), that is broken during electric discharge machining, by a wire electrode feed reel (1) to a state convenient for connection of the electrode. The mechanism has a clutch (3) having an output shaft (5) coupled to the wire electrode feed reel and creating a coupling torque between input and output members (3a, 3b) in a manner changing in accordance with a feed voltage, and a geared motor (M) coupled to an input shaft (6) of the clutch. When the wire electrode is broken, the feed reel is coupled to the geared motor, that is stopped, through the clutch which receives a high voltage and the input and output members of which are firmly engaged with each other, to be prevented from idling. The thus stopped feed reel is then driven by the geared motor at a predetermined torque and a low speed through the clutch which is supplied with a decreased voltage and loosely engaged, to rewind the wire electrode.
