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： The electric discharge machining apparatus of the wire-cutting type comprises a wire-treating unit (48) movable in the horizonal direction relative to an upper wire guide member (12) between the upper wire guide member and a work table (10) to traverse a wire electrode (W) extending downward from a wire passage (13) of the upper wire guide member. The wire-treating unit has a base block (55) and a movable block (56) that can approach to and separate from the base block to define a slit (60) and a nozzle hole (61) that can be opened and closed between the two blocks. The slit extends in the horizontal moving direction of the wire-treating unit to receive the wire electrode therein. The nozzle hole can be connected to the lower end of the wire passage of the upper wire guide member, and the nozzle hole is constructed so that a spray liquid supplied into the wire passage of the upper wire guide member can be injected into a wire passage (15) of a lower wire guide member (14). The wire-treating unit comprises a wire-detecting device (66) for detecting the end of the wire electrode between the base block and the movable block and wire-cutting means (62) for cutting the wire electrode between the base block and the movable block.

摘要： A wire guide consisting of a V-groove-type guide, a device for supplying machining liquid, and a die-type wire guide removably attached at the lower surface of the V-groove-type guide causes increased machining accuracy while used in both non-taper machining and taper machining modes. The increased accuracy is achieved after the wire passes through the V-groove-type guide by using the die-type wire guide to return the wire to a straight path to improve the linearity of the wire and, accordingly, improve machining accuracy.

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.

摘要： In a wire cut electric discharge machine, an apparatus is provided, which is capable of detecting completion of wire setting with a simple construction when a wire electrode (W) is automatically extended. Electric power is supplied to the wire electrode (W) from an electric power supplying section (43) through a contact (32) during automatic wire setting. When the wire electrode (W) is fed and brought into contact with an iron plate (44) disposed at a side at which the wire electrode (W) is taken out, an electric potential at the iron plate (44) of the electric power supplied section increases, to thereby detect completion of wire setting.

摘要： A position detection system includes a linear motor having a rod in which magnetic poles of N pole and S pole are arranged alternately in an axial direction and a plurality of coils surrounding the rod a magnetic sensor for detecting change in the direction of the magnetic field of the rod caused by linear movement of the rod relative to the coils to output a sine wave signal and a cosine wave signal which are 90° phase shifted with respect to one another, and a position detecting circuit for detecting a position of the rod relative to the coils. As the magnetic sensor detects the change in the direction of the magnetic field of the rod, the sine wave signal and the cosine wave signal output from the magnetic sensor hardly vary even when the distance between the rod and the magnetic sensor is changed.
