Abstract: A wire tension setting apparatus which is provided with a powder clutch (60) and a DC motor (48) on two respective parallel rotary shafts (66, 54). Although the rotation of the DC motor (48) is transmitted to the rotary shaft (66), on which the powder clutch (60) is provided, via a one-way rotation transmission means (56), the rotation of the rotary shaft (66) on the side of the powder clutch (60) is not transmitted to the DC motor (48). While a regular machining operation is carried out by the wire cut electric discharge machine, the wire tension setting apparatus applies a suitable level of tensile force to an electrode wire (2). In order to connect the electrode wire to another, the resistance of the wire tension setting apparatus transmitted to the electrode wire (2) is shut off by the one-way rotation transmission means (56).

Abstract: A wire-cut electrical discharge machine (1) is improved in its wire guide device (17) provided at a position where a wire path is flexed. The wire guide device (17) is composed of a wire guide roller (6) and a wire fall-off preventing member (16) fixed at one end thereof to a machine body (3). A part of a holding portion (22) provided on the wire fall-off preventing member (16) is fitted into a wire engaging groove (20) of the wire guide roller (6), and a holding groove (27) is provided on a surface of the holding portion (22), which is opposed to the groove bottom of the wire engaging groove (20). Furthermore, the holding portion (22) is disposed with a clearance slightly larger than the diameter of the wire (2) between the groove wall (26) of the wire engaging groove (20) and itself. During electrical discharge machining, even when the wire (2) is suddenly cut off for some reason or other, bounces up at the position of the wire guide roller (6) and moves to return along the wire path, the wire (2) has the energy of bounce-up and movement in the returning direction absorbed by the holding groove (27). With this arrangement, the wire is prevented from falling off the wire guide roller (6). On the other hand, to wind the wire (2) around the wire guide roller (6) anew, the wire can be put through the clearance formed between the holding portion (22) of the wire fall-off preventing member (16) and the groove wall (26) of the wire guide roller (6).

Abstract: A wire electrode guide apparatus for a wire cut electric discharge machine is provided which can always accurately support a wire electrode on a predetermined feed route during the electric discharge machining to thereby improving machining accuracy. The wire electrode guide apparatus (1) is provided with a change-over valve (80) for feeding or cutting off pressurized air to a pneumatic actuator (70) for driving a movable block (40) which three-point-supports the wire electrode (3) between the same and a fixing block. During the automatic wire-connecting, a pressurized air feed port (88) and a change-over port (87) at the change-over valve communicate with each other to feed pressurized air to the actuator so that a piston rod (73) leaves the movable block (40) to release an urging force applied thereto and the wire electrode is made insertable between the fixing block and the movable block. During the electric discharge machining, the change-over port is cut off from the pressurized air feed port and the pressurized air feed to the actuator is cut off, so that the actuator urges the movable block for supporting the wire. A high pressure machining liquid ejected from a nozzle (51) to enter the actuator through gaps between the respective units is discharged to the exterior through a pressure relief port (89), thereby preventing the urging force of actuator to be applied to the movable block from decreasing, thus accurately supporting the wire electrode on the predetermined feed route.

Abstract: This invention provides a wire driving apparatus for a wire electric discharge machine, which is capable of carrying out a wire connecting operation smoothly with a single driving power source, and preventing the abrasion of a belt and variations in wire feeding speed. During a wire connecting operation, a lower belt portion (3), which is supported via links (33, 34, 36, L) so that it can freely swing, is moved toward an upper belt portion (2) by the operations of air cylinders (10, 12), so that belts (21, 31) of these two belts portions come into press contact with each other. Wires are transferred by these two belts which are moved by the rotational force, which is transmitted via gears, of a wire driving roller (4) and connected together. After the wire connecting operation has been completed, the lower belt portion is moved to a position in which it is spaced from the wires. During this time, the upper belt portion is also spaced from the wires, and the transmission of power from the wire driving roller to the lower belt portion is stopped.
