In wire cut electrical discharge machining, as shown in FIG. 1, the wire electrode 1 is fed out from the feeding reel 8,
The wire electrode 1 is wound up by a take-up reel 8', and guided precisely by guides 5 and 5'.
In addition, the pulse from the processing pulse power source 4 is applied to the energized brush 6.
and 6' between the wire electrode 1 and the workpiece 2. Machining fluid supply nozzle 3
The machining fluid is supplied to the machining section by
The workpiece 2 is arbitrarily positioned by the NC device, and the workpiece is cut or cut out. Wire electrodes usually have a diameter of 0.03 mmφ to 0.3
mmφ, wires made of copper, brass, steel or other alloys are used. In this type of processing,
Based on the principle of electric discharge machining, the workpiece 2 is machined by thermally melting it by pulsed intermittent arc discharge and then removing it. At this time, the wire electrode side is also consumed and the diameter of the wire electrode 1 becomes smaller, so the wire electrode 1 is sequentially wound up by the take-up reel 8' to constantly supply new wire to compensate for the wire consumption. do. Furthermore, the tensile strength of the wire electrode 1 decreases due to the arc heat, making it more likely to break. To prevent wire breakage, in order to cool the wire electrode 1, it is desired to increase the winding speed of the wire electrode to shorten the time that the wire is exposed to the arc, but the wire electrode 1 wound on the feeding reel 8 is consumed as quickly as possible. In order to
Continuous machining for long periods of time becomes impossible. Also, Tokukai Akira
No. 58-45822 discloses a technique in which a wire 1 is wound around a rotating drum 10 as shown in FIG. 2, and the rotating drum 10 is rotated at high speed with the wire 1 in an endless state. In this case, in order to compensate for the wear of the wire electrode 1, the surface of the wire electrode 1 is plated by a plating device 11. However, since the wear of the wire electrode 1 is not uniform, the diameter of the wire electrode 1 cannot be made constant.

圧力の増大には、実用上の限界を有する。 Furthermore, if the machining fluid supply pressure from the machining fluid supply nozzle 3 is increased in order to improve the cooling effect of the wire electrode, the fluid in the machining section will stagnate, so there is a practical limit to increasing the machining fluid pressure. .

リールにより巻取ることができる。 Next, the operation of the present invention will be explained. The wire electrode 1 fed out from the feeding reel 8 is attached to a fixed pulley group 2
0 and the movable pulley group 21 in multiple stages, passing through the energized brush 6, guide 5, workpiece 2, and the other guide 5', energized brush 6', and guide rollers 7, 7', and then the other fixed Pulley 20' and moving pulley group 2
After passing through the wire electrode 1' in multiple stages, the wire electrode is wound up by a take-up reel 8'. The winding speed is adjusted by driving the winding reel by a motor (not shown), and the tension of the wire electrode is applied by a brake motor (not shown) brought into contact with the feed reel 8. On the other hand, the motor 24 has a gear 23
and 23' to rotate the female screw 25. By rotating this female screw, the movable pulley group 2
1, 21' are moved to the left or right. If the motor 24 is rotated at a constant period and a constant rotation angle,
The movable pulley groups 21, 21' reciprocate to the left or right with a fixed amount of movement. The details will be explained later. Here, first, it will be explained that the wire electrode 1 is sent out and reciprocated at high speed from side to side. Figure 4 shows fixed pulley group 2.
0, 20' and a detailed view of the moving pulley group 21, 21'. The pulley 201 is bonded to the outer race of the bearing 202, and the shaft 204 is inserted into the inner race of the bearing 202.
This inner race is fixed to the shaft 204 by an inner race fixing ring 203. The plurality of inner races are fixed to the stepped part 207 of the shaft by a nut 206 for screwing to the screw 205 at the left end of the shaft 204, and each of the pulley groups 201 can freely rotate independently. ing. The shaft 204 also has screw holes 2 for connecting the male screws 22, 22'.
08 is provided. A wedge sliding surface 209 for smooth sliding is provided on the end surface of the shaft of the movable pulleys 21, 21', and a fixed wedge surface 210 on the receiving side is formed on a bed serving as a base. When the reciprocating pulley moves left and right, the reciprocating length W and the moving distance l of the wire electrode 1
The following relationship holds true: l=2n・W However, n is the number of pulleys, and the larger the number of pulleys, the larger l becomes, and the reciprocating length of the wire electrode 1 becomes larger. . In this way, the wire electrode 1 can be reciprocated at high speed, and the wire electrode 1 can be wound up by the take-up reel by the amount of electrode consumption during electrical discharge machining.

行なうことができる。 In addition, in FIG. 3, the length of the wire electrode 1 that is let out or wound up between the fixed pulley group 20 and the movable pulley group 21 is
If the side is 1, then the guide roller 7 side is that N (however,
N is the number of times the wire electrode 1 is wound between the fixed pulley group 20 and the movable pulley group 21. ) double. but,
Even if there is a difference in the length of the wire electrode 1, since each pulley of each pulley group 20, 21 can rotate individually, the wire electrode 1 can be fed out or rolled in without slipping between the pulley and the wire electrode 1. can be done.
したがつて、ワイヤ電極１と滑車の摩擦による
ワイヤ電極１の摩耗をなくし、摩耗によるワイヤ
電極１の断線を防止することができる。 Therefore, wear of the wire electrode 1 due to friction between the wire electrode 1 and the pulley can be eliminated, and breakage of the wire electrode 1 due to wear can be prevented.

are limit switches installed on both sides of the moving pulley.
When the moving pulley presses the limit switch 301 or 302, the contact signal of the pressed limit switch is sent to the motor controller 303.
Reverse the direction of rotation. That is, when the movable pulley moves to the right due to clockwise rotation and the limit switch 301 is pressed, the limit switch 3
In response to the signal 01, the motor 24 reverses and rotates to the left, causing the moving pulley to move to the left. Next time you press the limit switch 302, do the same thing.
The motor 24 rotates clockwise and the pulley again operates to move to the right.

In addition, although the reversal drive of the moving pulley has been shown using a limit switch, as shown in FIG. 6, an arm 401 is provided,
The movable pulleys 201 and 201' may be configured to reciprocate in the rotational direction by the vertical semi-rotational shaft 402.

This shows that the wire current carrying capacity can be increased by this effect. That is, the winding speed of conventional wire electrodes was about 5 m/min, and the current carrying capacity in this case was 14 A, but as in the present invention,
If the wire feed speed increases to 100m/min, it can be increased to 50A.
