関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an electric discharge machining device, and in particular, the present invention relates to an electric discharge machining device, in particular, a machining fluid containing hydrocarbons, so-called petroleum (kerosene), in a machining gap.
Or electric discharge machining that prevents accidents such as fires by supplying petroleum mixed with a surfactant and water or water containing a surfactant to the machining tank to emulsify the machining fluid. Concerning improvements to equipment.

するには必ずしも万全ではなかつた。 However, there is a possibility of kerosene igniting during processing and causing a fire, so the liquid level in the tank must be kept at a constant level at all times, the processing tank must be sealed, and the temperature of the liquid must be strictly controlled. Although various measures have been taken, such measures have not always been sufficient to completely prevent fire accidents during long-term unmanned operation.

完全に防止されるものである。 In order to solve this problem, kerosene or surfactant-added kerosene is intensively supplied only to the processing area, and at the same time water or surfactant-added water is supplied to the processing tank. The processing part is immersed in the water in the processing tank, and the kerosene discharged from the processing part is emulsified with surrounding water to form an emulsion and collected in the processing liquid treatment device. Electrical discharge machining equipment designed to prevent fires has been proposed. In this way, pure kerosene will not float near the liquid surface where there is a risk of ignition, and the processing tank water will be mostly filled with the above-mentioned non-flammable emulsified liquid, resulting in a fire hazard. Occurrence can be completely prevented.

There were issues such as whether it was necessary.

The present invention was made to solve the above problems, and its purpose is to store water or water to which a surfactant (usually non-ionic, hereinafter the same) has been added in a processing tank. Then, the machining fluid kerosene, which was supplied to the machining gap between the electrode and the workpiece immersed in the water in the machining tank and used for the electric discharge machining action, comes out of the machining gap and mixes with the water. In electrical discharge machining equipment that prevents the occurrence of fires by mixing and forming emulsions, the kerosene, surfactants, water, etc. mentioned above can be collected and recycled without the need for large-scale control equipment. As a result, it is possible to prepare a large amount of machining fluid in a large tank in preparation for long-term unmanned operation, and there is no need for complicated equipment, making it suitable for space-saving purposes. Our goal is to provide processing equipment.

In order to achieve the above object, the present invention supplies petroleum or petroleum mixed with a surfactant as a machining fluid as a machining gap, and supplies water or water containing a surfactant to a machining tank. In electrical discharge machining equipment that emulsifies and recovers oil, there is a centrifugal separator that separates machining waste from the recovered emulsion, a centrifugal separator that separates and recovers the surfactant from the separated emulsion, and then separates petroleum and water. This is achieved by providing a machining fluid treatment device comprising at least one tank for storing the machining fluid.

With the above configuration, the processing waste is separated from the emulsion of kerosene and water recovered from the processing tank by the centrifugal separator, and the surfactant is extracted from the separated emulsion. Separate and recover using other characteristics, separate the separated and recovered liquid into kerosene and water, pass this through the storage tank above, and reprocess the kerosene and water to which a surfactant has been added as necessary to a tank. Since the circulation flow path is closed as a whole, the amount of kerosene, water, and surfactant in the device is equal to the amount of kerosene, surfactant, and surfactant consumed during processing. The water consumed by evaporation can be replenished as appropriate, and the mixing ratio can be controlled extremely easily using a small-sized control device. Furthermore, since the machining fluid is recycled without being disposed of, there is no need to prepare a large tank for long-term unmanned operation, and the accompanying equipment of the electric discharge machining apparatus can be greatly simplified.

This is because the fine particles of the remaining processing waste become the core of the surfactant that aggregates in the tank 19, and the separation of this surfactant causes the emulsion to be separated into the part containing kerosene as the main component in the collection tank 19. The centrifugal separator 18 may be small because separation of the kerosene and water proceeds rapidly in the processing liquid recovery tank 19.
