Description

Lower wire guiding apparatus of wire cut electric dischange machine

      BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lower wire guiding device of an EDM (Wire Cut) Electric Discharge Machine (EDM), and in particular, a power supply die without repeatedly disassembling the device, while repeatedly using a feeding die for supplying electricity to the wire. It relates to a lower wire guide device of the wire cut electric discharge machine that can be taken to reuse.

      The wire-cut electric discharge machine generates and discharges a predetermined voltage difference between the wire electrode and the workpiece to be processed, and simultaneously moves the workpiece relative to the wire electrode according to the machining command data to process the workpiece into a desired shape. In such electric discharge machines, the wire electrode may be disconnected inside the workpiece when the applied voltage during the discharge machining, the moving speed of the workpiece, and other processing conditions are not appropriate.

      In this way, the wire discharge machine is opposed to the wire electrode to maintain a small distance to the workpiece, repeatedly generating a pulsed discharge between the workpiece and the wire electrode continuously supplied automatically, cutting the workpiece by the discharge energy As the wire electrode, a very thin metal wire having a diameter of about 0.02 to 0.2 mm, particularly a copper wire is used.

      As described above, the wire discharge processing machine is to process the workpiece by using the discharge between the metal wire and the workpiece, and since the thickness of the metal wire used to generate the discharge is very thin and may be easily cut by high heat, supply the cooling water. And the wire electrode is continuously supplied to the wire electrode. As shown in FIG. 9, the wire is connected to the receiving side through the supply side wire guide 1, the workpiece 2, and the preformed start hole 3, as shown in FIG. After passing through (4), the used wire electrode 5 is collected in a storage box 6 for disposal.

      At this time, when the wire is broken for the first time or when the wire is disconnected, various methods are used to connect the wire, but recently, a method of pushing the wire into the device by a strong pressure and speed of jet flow is widely used. have.

      Representative techniques of this type include International Publication WO 90/12672, which is shown in FIG.

      The invention described above automatically removes the remaining portion 5-1 of the wire electrode 5 from the workpiece 2 when the wire electrode 5 is disconnected because an abnormal condition occurs before or during processing. (1) the new wire electrode (5-2) is passed through the hole (3) of the workpiece (2) and then inserted into the receiving wire guide (4) to start the pump (not shown) to operate the roller unit (7) The jet stream 8 is supplied to the inside.

At this time, the supply water pressure of the jet water stream 8 supplied is about 8 kgf / cm 2, and is discharged through the traction rollers 10 and 11 through the guide pipe 9 inside the roller unit 7 and stored in the storage box 6. Is recovered. In addition, the jet flow 8 acts to impart a conveying force to the wire electrode 5 in the guide pipe 9, that is, to transfer it to the traction rollers 10 and 11, and is provided inside the roller unit 7. Rotate pulley 12 in the direction of the arrow. The pulley 12 reduces the load when the wire electrode 5 inside the roller unit 7 changes direction by rotation and at the same time assists the transfer of the wire electrode 5 while rotating under the driving force of the jet stream 8. .

      The jet stream (8) passing through the guide pipe (9) is then discharged from the tow rollers (10) and (11) and recovered in the storage box (6) together with the wire electrode (5), but only the jet stream (8) separates the water. The plate 13 is separated from the wire electrode 5 and stored at the bottom of the recovery box 13.

      When the jet stream 8 stored in the storage box 6 reaches a predetermined level, the float switch 14 operates to drive the pump 15 and pump water from the storage box 6 to the processing liquid tank. Return to (16). In addition, when the jet streams 8 are discharged from the traction rollers 10 and 11, the roller parts 10 and 11 are opened, so that the flow of the jet streams 8 is improved and the pressure of the outlet of the guide pipe 9 is increased. The loss is reduced to secure the quantity of jet stream 8. That is, the roller 10 is pushed upward through the lever member 18 by the air cylinder 17 to remove the wire electrode 5 due to disconnection, etc., to open the rollers and disconnect the wire electrode 5. -1) is removed and the rollers 10 and 11 are closed when the new wire electrode 5-2 is supplied, so that the wire electrodes 5 are sandwiched between the rollers 10 and 11 and supplied.

      However, in order to generate a discharge between the wire electrode 5 and the work piece 2, a high voltage current must be flowed through the wire electrode 5, so that friction is applied to supply a current to the wire electrode 5 that is continuously transferred. A contact is required.

Accordingly, the supply side wire guide 1 and the roller unit 7 have mechanisms for feeding power.

      An example of the specific configuration of the lower wire guide device 30 (roller unit) installed in the electric discharge machining unit for the connection work by automatic transfer of the conventional wire is a guide roller for guiding the wire 31 to be fed as shown in FIG. A roller body 33 having a rotatable structure 32 mounted therein, and a die holder 34 fixedly mounted on the roller body 33 with a screw, and in the die holder 34, a feed die holder.

The guide roller 32 is wound around the outer circumference of the guide roller 32 by a jet flow force fed through the narrow nozzle hole 42 of the lower nozzle die 36, which is fed at high pressure along the jet flow passage 43. It is switched to pass through the outlet hole 44 and exit through the jet flow collector along the pipe (not shown).

In order to maintain certainty, the feeding die 37 is eccentrically installed with respect to the axis of the nozzle holes 41 and 42 to press the wire 31 through which the hole inner wall surface 45 of the feeding die 37 passes. It is configured to maintain forced contact in the form.

      However, according to the installation structure of the power feeding die 37, the wire 31 continuously conveyed passes through the hole inner wall surface 45, and after a predetermined time elapses, the hole inner wall surface 45 wears out. Due to this, the slit groove is formed, and if this causes a poor contact, it is necessary to replace the feeding die 37 with a new one when the feeding stability is not secured.

However, according to the conventional structure, in order to replace the feed dice 37, the entire lower guide device 30 had to be disassembled, and the feed dice 37 had to be taken out and assembled with new ones. In addition, the inconvenience of having to disconnect the wire (31) and re-wiring work, and accordingly there was a lot of unnecessary consumption of the wire.
