Description

Technical Field

[0001] The utility model relates to the technical field of electric spark machines, in particular to an oil tank of an electric spark machine. Background Art

[0002] Spark oil is an indispensable medium in the EDM industry. During processing, the spark oil in the EDM machine's oil tank has the functions of insulation, deionization, cooling local high temperatures, and removing carbon slag.

[0003] During the operation of an EDM machine, in addition to the wear of the discharge electrode and the carbon particles produced by the carbonization of the spark oil, the residues corroded from the blank during the EDM process will also remain in the EDM oil. The presence of these solid impurities will affect the processing quality and precision. The EDM oil needs to be replaced every once in a while. The high price and high consumption of EDM oil will undoubtedly increase the production cost of the EDM machine. If the waste EDM oil is directly discarded, it will cause serious environmental pollution. Some companies use large-scale distillation to separate the oil residue. Although the purification effect is good, the cost is high. The company's configuration of professional distillation purification equipment also leads to further cost increases.

[0004] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.

[0023] Reference Figure 1 As shown, the utility model provides an oil tank for an electric spark machine, comprising: an oil tank body 1, a slag removal box 2, and a cooler 3.

[0024] In this embodiment, the oil tank body 1 is a special-shaped box for accommodating spark oil. Specifically, the oil tank body includes a bottom plate 13 and side boxes. The bottom plate 13 of the oil tank body 1 is arranged at an angle. Side boxes are vertically arranged around the bottom plate. A base 11 is formed on the bottom plate 13. A tool electrode 12 is mounted on the base 11. The tool electrode is immersed in the spark oil. The base 11 is arranged at the upper end of the bottom plate 13. An oil drain port is opened on the side of the oil tank body 1. The oil drain port is aligned with the lower end of the bottom plate.

[0025] The slag removal box 2 is in the shape of a rectangular parallelepiped. In the width direction of the slag removal box, the slag removal box has two opposite sides. A partition plate 21 is connected between the lower parts of the two opposite side plates of the slag removal box 2.

[0026] The slag removal box has two opposing ends along its length. A slag collecting frame 22 is removably mounted between the side panel at one end of the slag removal box and the partition 21. The slag collecting frame is a container with a bottom but no lid. An inclined filter plate 23 is connected between the partition 21 and the upper portion of the side panel at the other end of the slag removal box 2. The filter plate has multiple oil holes. The diameter of the oil holes is smaller than the outer diameter of the residue eroded from the blank during the EDM process.

[0027] As a preferred embodiment, the upper end of the filter plate 23 is connected to the top of the side plate at the other end of the slag removal box 2.

[0028] An oil inlet is provided on a side plate at one end of the slag removal box 2. The oil inlet pipeline is connected to the oil discharge port. An oil outlet is provided on a side plate at the other end of the slag removal box 2.

[0029] The oil outlet of the slag removal box is connected to the oil tank body 1 through a delivery pipe. A cooler 3 is installed on the delivery pipe. The cooler is used to reduce the temperature of the spark oil in the delivery pipe so that the cooled spark oil flows back into the oil tank body.

[0030] In this embodiment, an oil pump 43 is installed in the delivery pipe.

[0031] As a preferred embodiment, the cooler 3 includes a metal elbow 31 and a heat dissipation plate 32 .

[0032] The metal elbow 31 is S-shaped. Preferably, the metal elbow 31 is a copper elbow.

[0033] The delivery pipe includes an upstream pipe section 41 and a downstream pipe section 42. The upstream pipe section 41 is connected to the oil outlet and one end of the metal elbow 31. The downstream pipe section 42 is connected to the other end of the metal elbow 31 and the oil tank body 1.

[0034] There are multiple heat sinks 32. The heat sinks 32 are connected to the metal elbow 31. Preferably, the heat sinks 32 are copper plates.

[0035] The fuel tank of the electric spark machine of the present invention also includes a controller and a temperature sensor. The temperature sensor is installed in the fuel tank body 1. The temperature sensor is used to collect the temperature of the spark oil. A fan is installed on one side of the cooler 3. The controller is connected to the temperature sensor and the fan.

[0036] In this embodiment, during machining, while maintaining a constant discharge gap between the tool electrode and the workpiece electrode, the tool electrode is continuously fed toward the workpiece electrode while etched away metal from the workpiece, ultimately producing a shape corresponding to the tool electrode. Debris removed from the blank falls into the spark oil within the oil tank. Under normal conditions, the oil pump's suction draws the spark oil, filtered by the filter plate in the slag removal box, through a delivery pipe. The spark oil, carrying debris within the oil tank, is discharged through a pipeline into the slag removal box on the first side of the filter plate. Some of the debris settles in the slag sump, while some adheres to the first side of the filter plate due to suction from the delivery pipe. The slag removal box is a sealed box with a top opening. A lid is sealed within the opening. When a large amount of debris adheres to the slag sump or filter plate, the lid is opened and the debris on the filter plate is scraped into the slag sump. The slag sump is then removed from the slag removal box, cleaned, and returned to the box. The filtered spark oil is discharged back into the oil tank through the delivery pipe for reuse.

[0037] During the return process, the cooler cools the spark oil in the delivery pipe, stabilizing the temperature of the spark oil in the fuel tank at a preset temperature. When the temperature of the spark oil in the fuel tank exceeds the preset temperature, the controller detects the temperature value collected by the temperature sensor and activates the fan, which increases the cooling efficiency of the cooler and further reduces the temperature of the spark oil.

[0038] The oil tank of the electric spark machine of the present invention draws filtered spark oil from a deslagging box through a delivery pipe, cools it in a cooler, and then discharges it back into the oil tank body. During the delivery pipe drawing process, spark oil containing residue in the oil tank body flows into the deslagging box through the pipeline. Some of the residue settles in a slag collecting frame, while some of the residue adheres to the first side of the filter plate during the drawing process through the delivery pipe. The slag collecting frame can be removed to remove the residue, thereby ensuring the cleanliness and temperature of the spark oil in the oil tank body, thereby improving workpiece processing efficiency and quality.

[0039] The above description is merely a preferred embodiment of the present application and an illustration of the technical principles employed. Those skilled in the art should understand that the scope of the utility model disclosed in this application is not limited to the technical solutions formed by the specific combination of the above-mentioned technical features, but also encompasses other technical solutions formed by any combination of the above-mentioned technical features or their equivalents without departing from the concept of the utility model.
