Изобретение относитс  к области электрохимической обработки и может использоватьс  на машиностроительных предпри ти х.The invention relates to the field of electrochemical processing and can be used in machine-building enterprises.

Известны способы электрохимической трепанации отверстий в детал х из ферромагнитного сплава полыми электродами-инструментами . При обработке такими электродами-инструментами в отверстии остаетс  нерастворившийс  центральный стержень, который в случае сквозной прошивки может сдвигатьс  потоком электролита и производить короткое замыкание в цепи технологического тока.Methods are known for electrochemical trepanning of holes in ferromagnetic alloy parts by hollow electrode electrodes. When machining with such tool electrodes, an insoluble core remains in the hole, which, in the case of through-piercing, can be shifted by electrolyte flow and produce a short circuit in the process current circuit.

Целью изобретени   вл етс  обеспечение возможности удержани  нерастворившегос  центрального стержн  от сдвига.The aim of the invention is to enable the insoluble central rod to be kept from shear.

Поставленна  цель достигаетс  тем, что обрабатываема  деталь устанавливаетс  на ферромагнитную пластину, намагничивающуюс  в электромагнитном поле технологического тока и силой остаточиого магнетизма, удерживающую нерастворившийс  стержень от сдвига.The goal is achieved by installing the workpiece on a ferromagnetic plate that is magnetized in the electromagnetic field of the process current and a residual magnetism force that holds the undissolved rod from shear.

Сущность способа по сн етс  чертежом.The essence of the method is illustrated in the drawing.

Обрабатываема  деталь / прижата к ферромагнитной пластине 2. Деталь обрабатываетс  электродом-инструментом 3 с образованием центрального стержн  4.The workpiece / pressed to the ferromagnetic plate 2. The part is processed by the electrode tool 3 to form the central rod 4.

При включении технологического тока ферромагнитна  пластина 2 намагничиваетс . В момент окончани  прошивки удерживаютс  деталь / и стержень 4. В момент окончани  прошивки электродом-инструментом стержень не сдвигаетс , так как его удерживает пластина 2, что предотвращает короткое замыкание в цепи технологического тока. После выключени  тока деталь и стержень легко снимаютс  с пластины.When the process current is turned on, the ferromagnetic plate 2 is magnetized. At the moment of the end of the firmware, the part / and the rod 4 are held. At the time of the end of the firmware by the electrode-tool the rod does not move, since plate 2 holds it, which prevents a short circuit in the process current circuit. After the current is turned off, the part and the rod are easily removed from the plate.

Предмет изобретени Subject invention
