(54) ПОДВЕСКА ДЛЯ ЭЛЕКТРОХИМИЧЕСКОЙ ОБРАБОТКИ ДЕТАЛЕЙ(54) SUSPENSION FOR ELECTROCHEMICAL TREATMENT OF DETAILS

Изобретение относитс к гальваностегии, в частности к подвескам дл электрохимической обработки деталей.The invention relates to electroplating, in particular to suspensions for the electrochemical machining of parts.

Известна подвеска дл электрохимической обработки деталей, включающа магаиты дл подведени рабочего тока к обрабатываемой детали через сердечник электромагнита, удерживающего ее 1.The known suspension for electrochemical machining of parts, including magayites for supplying the working current to the workpiece through the core of the electromagnet holding it 1.

Недостаток этой подвески в том, что она не может быть полностыо погружена и работать в разогретом электролите.The disadvantage of this suspension is that it can not be completely immersed and work in a heated electrolyte.

Известна также подвеска дл электрохимической обработки деталей, содержаща щтангу, корпус с магнитами и контактные пластины с упругим элементом дл креплени пласт ш к корпусу, при этом корпус с магнитами выполнен с возможностью осевого перемещени , а магаиты жестко закреплены в контактной пластине 21.Also known is a suspension for electrochemical machining of parts, comprising a shank, a body with magnets and contact plates with an elastic element for fastening the layer to the body, while the body with magnets is axially displaceable, and the magites are rigidly fixed in the contact plate 21.

Да1ша конструкци вл етс наиболее близкой к изобретению по технической сущности и достигаемому результату.This design is the closest to the invention in its technical essence and the result achieved.

Однако в известной подвеске магнит жестко закреплен в контактной шшстине и поэтому контакг деталей с контактными пластинами с However, in the known suspension, the magnet is rigidly fixed in the contact ring and therefore the contact of parts with contact plates with

каждым разом завешивани будет ослабл тьс , а, следовательно, и прижим деталей к контактным поверхност м пластин также будет слабее. Это вызывает брак деталей и уменьшает фок службы контактных пластин.each time, the hanging will be weakened, and, consequently, the clamping of parts to the contact surfaces of the plates will also be weaker. This causes rejection of parts and reduces the service life of the contact plates.

Целью изобретени вл етс повышение срока службы подвески и качества обработки путем обеспечени надежного прижима деталей к контактным пластинам.The aim of the invention is to increase the service life of the suspension and the quality of processing by ensuring reliable clamping of parts to the contact plates.

Поставленна цель достигаетс тем, что подвеска, содержаща раму и контактные пластины с магнитами, снабжена упругими гофрированными трубками, жестко закрепленными одним кондом на магните, а другим - на коитактной пластине, при этом контакл1а пластина выполнена с отверсти ми дл магнитов, уста новленных с возможностью осевого перемещени в них и внутри гофрирова1шых трубок.The goal is achieved by the fact that the suspension, containing the frame and contact plates with magnets, is provided with elastic corrugated tubes rigidly fixed with one condom on the magnet and the other on a co-tact plate, while the contact plate is made with holes axial movement in them and inside the corrugated tubes.

Claims

The suspension for the electrochemical machining of parts consists of a frame 1, a contact H1.1x of current-carrying plates 2 with copper, brass or lead nJCinKami 3 fixed on them. 3 In the plates 2 and 3 B1 strips there are holes, the magnets 4 are inserted into elastic Corrugated tubes 5 , creating the necessary force of pressing the parts to contact current-carrying plates 2 and strips 3. In the case of electrolyte getting into a corrugated tube, in the latter there is an opening for quick discharge of electrolyte. During operation, the magnet 4 is removed from the hole, is brought to the part 6, which is pulled by the magnet. Under the action of the elastic force of the corrugation of the tubing tube 5, the magnet is drawn into the hole and carries the uddle away with it, KOjopta is firmly pressed against the current-carrying surface of the strip 3. Each suspension bus for the electrochemical machining of parts is working. In order to improve the durability of the suspension, to avoid dissolving the corrugated tube, the magnets and the suspension are insulated with coziness, plastisol, thermoplastic, ighelite, fluoroplastic three, followed by stripping the contacts on the current-carrying plates. The thickness of the insulation layer applied is sufficient to protect the suspension and the magnets from dissolving the metal during chemical or electrochemical processing and does not significantly affect the magnet strength. The removable suspension is easy to manufacture, provides reliable electrical ontact of all parts with a current-carrying plate, which makes it possible to quickly assemble and disassemble parts. Mash, placed in a corrugated wheelhouse and absorbing axial forces from it, reliably presses the product against the contact surface of the suspension during the entire processing. Claims for electrochemical machining of parts, containing frame and contact plates with magnets, characterized in that, in order to guide the suspension service and quality of processing by providing reliable ui pressing parts to contact plates, it is provided with elastic corrugated tubes, rigidly fixed with one magnet on the magnet, and the other on the contact plate, last filled with openings for the magnets, and the magnets are mounted with the possibility of axial heat in them and inside the corrugated side.
