The invention discloses an engine-oil cooling and filtering device for an electric-spark machine tool. The engine-oil cooling and filtering device comprises an oil tank, a first filtering pump, a filter and a second filtering pump, wherein the oil tank is internally provided with a dirty oil area and a clean oil area; the input end of the second filtering pump is communicated with the clean oil area; the dirty oil area is internally provided with a heat exchanger; a cooling flow channel is distributed in the heat exchanger; the outer side of the oil tank is provided with a radiator; and the cooling flow channel of the heat exchanger is connected with the radiator by a medium pipeline. The engine-oil cooling and filtering device disclosed by the invention has the advantages that the heat exchanger is arranged in the oil tank, the radiator is arranged outside the oil tank, and the heat of dirty oil in the dirty oil area is taken out of the oil tank by utilizing a cooling medium, so that the temperature of the dirty oil is reduced, the filtering effect is improved and the benefit for cooling and lubricating the machine tool is achieved.
Description
Technical field: [0001] The invention relates to the field of machinery, in particular to an electric discharge machine tool, in particular to an engine oil circulation system in an electric discharge machine tool, in particular to an engine oil cooling and filtering device for an electric discharge machine tool. Background technique: [0002] During the working process of the EDM machine tool, it is necessary to use oil to lubricate and cool the moving parts. The oil runs in a circulating system. A filter is installed in the circulation system, and the dirty oil is sent back to the lubricating and cooling oil channel by the filter pump after being filtered. Due to the resistance of the filter to the oil, the oil flow and pressure back to the lubricating and cooling oil passages are small. The applicant proposed a filter device for electric discharge machine tool in CN202751874U Chinese patent. The filter device for this electric discharge machine tool includes a fuel tank...
