For example, in wire-cut electrical discharge machining, machining fluid is normally applied to both the upper and lower surfaces of the workpiece in the machining gap formed between the workpiece and a wire electrode made of a thin wire that is fed in the axial direction. This machining liquid is supplied in a jet from the machining tank, falls as a drip or water stream into the machining tank provided below, bounces off the bottom of the machining tank, and becomes splashes in all directions, scattering around the machining equipment. Not only will the spray of machining fluid cause rust on various equipment in the workplace, but
The machining fluid after machining contains tar and machining debris generated by electrical discharge machining, and when these tar and machining debris scatter and float, they contaminate the working environment and harm the health of workers. It's possible.

In view of these points, the present invention aims to prevent rust caused by large and small droplets that are formed when machining fluid that is sprayed into the machining section and falls into the machining tank bounces off the bottom of the machining tank. This is proposed for the purpose of preventing the generation and contamination of the working environment, and a plate made of a flexible material mixed with magnetic particles (including permanent magnets) with an uneven bottom shape is placed inside the processing tank. By arranging the machining fluid in the machining tank, the machining fluid falling into the machining tank prevents splashing due to the rebound, and machining debris in the machining fluid is attracted and captured by a magnet. It is.

10 is a machining fluid treatment device placed in the machining tank 8;
It is composed of a plate whose surface is formed into an uneven shape by mixing magnetic particles 12 into a flexible material 11 such as rubber or synthetic resin. In this embodiment, the uneven surface shape is formed into a large number of spherical shapes 13. As magnetic particles, permanent magnet particles 12 are mixed into the flexible material.

In the above configuration, the machining liquid is supplied from the nozzle 5 to the machining gap 6.
Electric discharge machining is performed by applying a pulse voltage between the workpiece 1 and the wire electrode 4 that is fed in the axial direction while supplying the machining liquid in the nozzle 5. After passing through the machining gap 6, the remaining machining fluid falls into the machining tank 8 from both the upper and lower surfaces of the workpiece 1.

Therefore, a processing device 10 is disposed in the processing tank 8, and the falling processing liquid falls on the uneven surface of the processing device 10. Moreover, the processing device 10
Since it is made of a material that is flexible and elastic, the kinetic energy of the falling machining fluid is rapidly attenuated and consumed due to the complex impact rebound phenomenon on the flexible uneven surface. The rebound is extremely small, and the machining fluid does not become droplets and scatter around the surroundings, and the machining fluid flows down the many uneven surfaces and flows into the machining tank 8 from above the processing device 10, and is processed from the fluid outlet 9. It is discharged outside the tank.

In addition, in this embodiment, the uneven surface of the surface has a spherical shape 13
Because of this, the machining fluid that falls and collides with the many rounded spherical surfaces is smoothly discharged along the spherical surfaces without bouncing back.

Furthermore, the entire processing device 10 has the property of a magnetic magnet, and on the other hand, since nearly 90% of the workpiece is made of iron, it may get mixed into the processing fluid from the processing gap 6 and enter the processing tank. The falling machining debris (iron powder) flows down the convex portion of the processing device 10 together with the machining liquid, and while flowing through the concave portion, is attracted and captured on the surface of the processing device by a magnet.

In addition, in the machining fluid treatment device of the present invention, if the uneven surface portion is immersed in the machining fluid up to the top, the falling machining fluid will bounce back violently and scatter as many droplets. Therefore, as shown in FIG.
A hole is made in the processing device 1 to provide a liquid outflow path 16.
The processing fluid can be quickly drained from the top surface of the processing device by arranging the processing device 0 at a distance from the bottom of the processing tank 8 by means of the feet 17, or by providing grooves or unevenness on the bottom surface of the processing device 10 to serve as a water conduit. It is preferable to do so.

Products of various shapes are molded into a composite or combination of one or more types.

FIG. 5 shows a case in which the surface of the processing device is formed into a large number of cone-like shapes 18. In this way, if a large number of elongated needle-like cones are provided, the processing fluid that rebounds at the bottom of the recess on the surface of the processing device can be reduced. The material simply collides with the conical surface that rises around it and falls back to the bottom, and does not scatter around the processing tank as droplets.

FIG. 6 also shows an inclined plate 1 on the surface of the processing device.
6A is a front view, and FIG. 6B is a plan view, in which a large number of cylindrical convex portions 9 and 20 are provided in parallel. In this case, the machining fluid that falls onto the surface of the processing device Instead of directly falling and colliding with the bottom of the surface recess, it will contact and collide with the sloped plate or the sloped surface of the cylinder 20 before flowing down to the bottom, and it will bounce off the sloped surface of the plate 19. The machining fluid collides with adjacent plates and cylinders and falls to the bottom, so there is no possibility of machining fluid splashing around the machining tank.
In this case, the machining fluid does not fall directly to the bottom of the surface recess, but flows down to the bottom along the slope of the plate 19, so the contact area and contact time between the machining fluid and the processing device are large. Therefore, machining debris in the machining fluid can be efficiently attracted and captured by the magnet.

Further, in the case of FIG. 6, a configuration may be adopted in which inclined plates are arranged concentrically in parallel around a spherical convex portion.

As described above, according to the present invention, the kinetic energy of the machining fluid falling into the machining tank is attenuated and consumed by the complex contact collision phenomenon on the uneven surface, and the machining fluid turns into droplets and spreads around the machining equipment. This prevents contamination of the working environment and the occurrence of rust on equipment in the workplace, and the machining waste (iron powder) contained in the machining fluid after machining is attracted and captured by the magnet. Therefore, purification of the processing fluid becomes easy and the life of the filtration filter can be extended.
