Description

Изобретение относитс  к способам электроискрового шлифовани  металлических изделий в диэлектрической среде.The invention relates to methods for the electric-spark grinding of metal products in a dielectric medium.

Известны способы шлифовани  металлических изделий электроискровыми установками, дл  которых при работе на однофазном переменном токе требуетс  наличие выпр мител . Известно также получение выпр мленного однофазного переменного тока при условии вращени  одного электрода с большой скоростью. Однако, если электроды помещены в диэлектрической газовой среде, выпр мленный ток имеет характер неустойчивый и малоэффективен.Methods are known for grinding metal products with electric-spark installations, for which the presence of a rectifier is required when operating on single-phase alternating current. It is also known to obtain rectified single-phase alternating current under the condition that one electrode rotates at high speed. However, if the electrodes are placed in a dielectric gas medium, the rectified current has an unstable character and is ineffective.

Предлагаемый способ ликвидирует этот недостаток тем, что оба электрода (быстро вращающийс  электрод-инструмент и электродизделие ) помещают в диэлектрическую жидкую среду.The proposed method eliminates this drawback by the fact that both electrodes (a rapidly rotating electrode tool and an electro-device) are placed in a dielectric liquid medium.

С этой целью обрабатываемое изделие и дисковый электрод-ииструмент подключают к источнику однофазного тока непосредственно (т. е. без выпр мител ). Шлифование производ т в услови х быстрого вращени  электрода-инструмента в диэлектрической жидкой среде дл  придани  межэлектродгшму промежутку вентильных свойств и получени  в нпм импульсов тока одного направлени .For this purpose, the workpiece and the disk electrode and the instrument are connected directly to the single-phase current source (i.e., without a rectifier). Grinding is performed under conditions of rapid rotation of the electrode tool in a dielectric liquid medium to impart an inter-electrode gap to the properties of the valve and to obtain current pulses of one direction in the npm.

На чертеже показана схема установки дл  осуществлени  предложе П1ого способа, где: / - понижающий трансформатор, 2 -конденсатор , 3 и - - электрод-инструмент и обрабатываема  деталь, помещенные в ванну с жидким диэлектриком 5.The drawing shows the installation diagram for the implementation of the first method, where: / - step-down transformer, 2-capacitor, 3 and - - electrode-tool and the workpiece, placed in a bath with a liquid dielectric 5.

Электрод-инструмент вращаетс  много быстрее, чем обрабатываема  деталь Это придает межэлектродному промежутку вентильные свойства, обеспечивающие получение в нем импульсов тока одного направлени . В результате, деталь шлифуетс .The electrode tool rotates much faster than the workpiece. This imparts valve properties to the interelectrode gap, providing current pulses of one direction in it. As a result, the part is polished.
