Description
Technical Field
The utility model relates to a spark machine processing auxiliary assembly field specifically is spark machine oil drain mechanism.
Background
Machining is not needed in the manufacturing of the die or the machine, the types of machining are very many, and a lathe, a grinding machine, a milling machine, a drilling machine, a planer, a boring machine and a slotting machine are common, and a spark machine and a wire cutting machine are also common.
During electric spark machining, the tool electrode and the workpiece are connected to two poles of pulse power source and soaked in the working liquid or the working liquid is filled into the discharge gap. The feeding of the tool electrode to the workpiece is controlled by the automatic gap control system, and when the gap between the two electrodes reaches a certain distance, the pulse voltage applied to the two electrodes breaks down the working liquid to generate spark discharge. A large amount of heat energy is instantaneously concentrated in a discharge micro-channel, the temperature can reach more than 10000 ℃, and the pressure is also changed rapidly, so that a part of trace metal material on the working surface is melted and gasified immediately, splashed into working liquid in an explosive manner, and condensed rapidly to form solid metal particles which are taken away by the working liquid. At this time, a tiny pit mark is left on the surface of the workpiece, the discharge is stopped for a short time, and the working fluid between the two electrodes is restored to an insulating state. Then, the next pulse voltage is broken down at another point where the two electrodes are relatively close to each other, so that spark discharge is generated, and the process is repeated. Thus, although the amount of metal to be removed by the pulse discharge is extremely small, a large amount of metal can be removed by the pulse discharge operation several thousands of times per second, and the productivity is high.
The workpiece is continuously fed with the tool electrode while the metal of the workpiece is etched away under the condition that the discharge gap between the tool electrode and the workpiece is kept constant, and finally, the shape corresponding to the shape of the tool electrode is machined. Therefore, various complex profiles can be machined by changing the shape of the tool electrode and the relative motion mode between the tool electrode and the workpiece. The tool electrode is usually made of an electric-corrosion-resistant material which has good conductivity, a higher melting point and is easy to process, such as copper, graphite, copper-tungsten alloy, molybdenum and the like. The tool electrode is also lossy during machining, but less than the amount of work piece metal removed, even close to lossless. The working fluid is used as a discharge medium and also plays roles of cooling, chip removal and the like in the machining process.
