Изобретение относитс к гальвано- ;гшастргческому изготовлению деталей, :в частности к химическому разрушению и удалению оправок, на которые производитс гальваническое осаждение металла , и может быть использовано при |-изготовлении волноводов. ; Целью изобретени вл етс повышение производительности.The invention relates to the manufacture of galvanic; parts manufacturing,: in particular, chemical destruction and removal of mandrels for which galvanic metal is deposited, and can be used in | - fabricating waveguides. ; The aim of the invention is to increase productivity.
На фиг. 1 изображено устройство дл удалени разрушаемой оправки; на : фиг. 2 - торец трубки с коронкой из i двух зубцов.FIG. 1 shows a device for removing a breakable mandrel; in: FIG. 2 - end of a tube with a crown of i two teeth.
I В устройстве гальванически изго- I товленную деталь V (фиг.1) с алюмини- I евой оправкой 2 устанавливают в дер- I жатель 3 ванны 4, сообщающейс с I емкостью 5 злектролита на сливе тру- I бой 6. Электролит из емкости 5 пода- i ют под напором насо.сом 7 в трубки 8 I и 9-подачи электролита в деталь 1 с I оправкой-2. Трубки 8 и 9 со стороны I входа в оправку 2 имеют скосы 10 дл обеспечени свободного поступлени электролита в деталь 1. Трубки 8 и ; .9 св заны со стержн ми 11 и 12 с по- i мощью осей поворота 13 и 14, а между i собой стержни 11 и 12 щарнирно сое- ; динень осью 15 дл перемещени навет- : речу друг друга пружиной 16, закреп- ; ленной в отверсти х 17 и 18.I In the device, a galvanically manufactured part V (Fig. 1) with an aluminum I mandrel 2 is installed in the holder 3 of the bath 4, which is connected to I by tank 6. Electrolyte from the tank 5 It is supplied under pressure from pump 7 to the tubes 8 of the I and 9 electrolyte supply to the part 1 with the I mandrel-2. The tubes 8 and 9 from the side I of the entrance to the mandrel 2 have bevels 10 to ensure free flow of electrolyte into the part 1. The tubes 8 and; .9 are connected with the rods 11 and 12 with the help of i by means of the axes of rotation 13 and 14, and between i with themselves the rods 11 and 12 are jointly hinged; Dinin axis 15 to move libel-: speaking each other by a spring 16, fastened; in holes 17 and 18.
Устройство дл удалени разрушаемой оправки работает следующим образом .The device for removing the breakable mandrel operates as follows.
При подаче электролита с помощью «насоса 7 из емкости 5 через отверсти трубок 8 и 9 происходит разрушение оправки 2. Оно происходит тем интенсивнее , чем интенсивнее осуществл ет- с подача электролита.When the electrolyte is supplied by means of a pump 7 from the tank 5 through the openings of the tubes 8 and 9, the mandrel 2 is destroyed. It becomes more intense the more intensively the electrolyte is supplied.
По мере разрушени оправки 2 трубки -8 и 9 перемещаютс навстречу друг другу в детали 1 при подаче свежего электролита непосредственно на торцы оправки 2.As the mandrel 2 is destroyed, the tubes -8 and 9 move towards each other in part 1 when fresh electrolyte is supplied directly to the ends of the mandrel 2.
llfl.n исключени закупировани отверстий в трубках 8 и 9 их торцы; 10 выполн ют со скосами либо в виде коронок с двум и более зубцами 19 (фиг.2).llfl.n exclude the procurement of holes in the tubes 8 and 9, their ends; 10 are made with bevels or in the form of crowns with two or more teeth 19 (FIG. 2).
Отработанный электролит удал ют по трубе 6 из ванны 4 в емкость 5 самотеком.The spent electrolyte is removed through pipe 6 from bath 4 to tank 5 by gravity.

При реализации предлагаемого устройства при удалении алюминиевой оп- равки используют 20%-ный раствор щелочи , например NaOH. При этом скорость растворени оправки увеличиваетс в 5-7 раз по сравнению с разрушением оправки при простом ее погружении в ванну со щелочью. Особедно это сказываетс при разрушении оправок малого сечени , например волновода се .- чением 2x4 мм,имеющего большую длину пор дка 400-600 мм,In the implementation of the proposed device, a 20% alkali solution, for example, NaOH, is used in the removal of aluminum trim. At the same time, the rate of dissolution of the mandrel is increased by 5-7 times compared with the destruction of the mandrel when it is simply immersed in a bath with alkali. This is especially true when the shafts of small cross section, for example, a waveguide with a length of 2x4 mm, having a length of about 400-600 mm,
При использовании предлагаемого устройства увеличиваетс производительность в 5-7 раэ при разрущении оправки и сокращаютс технологическое оборудование, занимаемые производственные площади, количество обслуживающего персонала.When using the proposed device, the productivity increases by 5-7 rae when the mandrel is destroyed and the technological equipment, the occupied production areas, the number of service personnel are reduced.
