(54) СПОСОБ ЭЛЕКТРОЭРОЗИОННОЙ ОБРАБОТКИ СЕКЦИОННЬМ ЭЛЕКТРОДОМ(54) METHOD OF ELECTRIC EROSIS TREATMENT BY SECTIONAL ELECTRODE

прикосновении между собой и соединенных с генератором электрических импульсов 2. Обрабатываема  деталь 3, расположенна  на столе 4, размещаетс  в ванне 5, заполненной рабочей средой.touching each other and the electrical impulses connected to the generator 2. The workpiece 3, located on the table 4, is placed in a bath 5 filled with the working medium.

Кажда  секци  1 электрода-инструмента закреплена на подпружиненном штоке б, расположенном в скобе 7.Each section 1 of the electrode tool is mounted on a spring-loaded rod b located in the bracket 7.

Последовательнь1е подвод и отвод секций электрода-инструмента относйтельно обрабатываемой поверхности осуществл ют от кулачков 8. Кулачки закреплены в требуемой последовательности на распределительном валу 9. Очередность сближени  и отвода секций определ етс  углом установки кулачков 8. Вращение распределительного вала осуществл етс  от двигател Ю , посто нного тока, закрепленного в скобе 7, хвостовик 11 которой крепитс  в электродержателе станка.Sequential approach and removal of the electrode-tool sections relative to the surface to be treated is carried out from the cams 8. The cams are fixed in the required sequence on the camshaft 9. The sequence of approach and removal of the sections is determined by the installation angle of the cams 8. Rotation of the camshaft is carried out from the engine constant current, fixed in the bracket 7, the shank 11 of which is attached to the electric holder of the machine.

Процесс электроэ о.зионной обработки происходит на каждую секцию следующим образом: на каждую секцию электрода-инструмента подают ток кратковременными импульсами. Одновременно с этим происходит сближение одной из секций 1 с обрабатываемой поверхностью до величины, соответствующей межэлектродному зазору. Это приводит к возникновению электрических импульсов между электродами, В то же врем  секции, наход щиес  на рассто нии большим величины межэлектродного зазора в .данный моментвремени в работе не участвуют. Это позвол ет качественно удаЛ ть продукты эрозии из зоны обработки.The process of electric power processing occurs on each section as follows: on each section of the electrode-instrument, current is supplied with short pulses. At the same time, one of the sections 1 approaches the surface to be processed to the value corresponding to the interelectrode gap. This leads to the appearance of electrical impulses between the electrodes. At the same time, sections that are located at a distance greater than the size of the interelectrode gap at this time point are not involved in the work. This allows for the qualitative removal of erosion products from the treatment area.

Эффект эвакуации продуктов эрозии значительно усиливаетс  при движении следующей секции к обрабатываемой поверхности с последующим отводом ранее заботающей. В этом случае активныйThe effect of evacuating erosion products is greatly enhanced by the movement of the next section to the treated surface, followed by the removal of the previously concerned one. In this case, the active

выброс продуктов эрозии происходит в результате насосного действи  движущейс  секции. В . последутп-.ем процессе эрозиОнна  обработка происходит аналогичным образом.the release of erosion products occurs as a result of the pumping action of the moving section. AT . The subsequent erosion process is done in a similar way.

Очередность Поступлени  в работу секций электрода-инструмента зависит от конфигурации обрабатываемой поверхности и других технологических показателей , а также от заданной программы действи  кулачков на распределительном валу.The order of entry into the work of the electrode-tool sections depends on the configuration of the surface being processed and other technological indicators, as well as on the specified cam action program on the camshaft.

Проведенные испытани  способа показали значительное улучшение условий эвакуации продуктов эрозии,что обеспечило высокую стабильность процесса , особенно на чистовых режимах.Conducted tests showed a significant improvement in the evacuation of erosion products, which ensured a high process stability, especially in clean conditions.
