Description
Изобретение относитс к защитным приспособлени м дл химического фрезеровани плоских металлических поверхностей по заданному контуру и на заданную глубину.The invention relates to protective devices for chemical milling of flat metal surfaces along a predetermined contour and to a predetermined depth.
Известные аналогичные приспособлени предусматривают применение защитных покрытий, преграждающих доступ агрессивной среды к част м издели , не подлежащим обработке. Недостатком этих приспособлений вл етс невозможность многократного их использовани , а также подтравливание кромок обрабатываемого контура.Known similar devices provide for the use of protective coatings that block the access of aggressive media to parts of the product that cannot be processed. The disadvantage of these devices is the impossibility of their repeated use, as well as the undercutting of the edges of the contour to be machined.
Дл устранени этих недостатков предлагаетс приспособление, выполненное в виде подвижного кессона с острыми кромками, которые повтор ют заданный контур обрабатываемого издели и прижимаютс к поверхности издели . Внутренн часть кессона заполнена нейтрализующей жидкостью с избыточным давлением. Дл повыщени герметичности кромки кессона гуммируютс .To eliminate these drawbacks, a device made in the form of a movable caisson with sharp edges is proposed, which follow a predetermined contour of the workpiece and press against the surface of the product. The inner part of the caisson is filled with neutralizing fluid with excess pressure. The edges of the caisson are gummed to increase tightness.
На фиг. 1 показано приспособление дл фрезеровани периферийной части поверхности издели ; на фиг. 2-приспособление дл фрезеровани центральной части издели .FIG. Figure 1 shows a device for milling the peripheral portion of the surface of an article; in fig. 2 is a device for milling the central part of the product.
Кессон 1, снабженный острыми кромками 2, прижимаетс усилием Р к поверхности обрабатываемого издели 5. Кромки кессона образуют замкнутую полость и отдел ют пространство, заполненное травильной жидкостью 4, от пространства с нейтрализующей жидкостью 5. Дл подвода соответствующей жидкости в кессон служит трубка 6.Caisson 1, equipped with sharp edges 2, is pressed by force P to the surface of the workpiece 5. The edges of the caisson form a closed cavity and separate the space filled with the pickling fluid 4 from the space with the neutralizing fluid 5. A tube 6 serves to supply the corresponding fluid to the caisson.
Давление нейтрализующей жидкости превыщает давление травильной жидкости.The pressure of the neutralizing fluid exceeds the pressure of the pickling fluid.
Труба 7 служит дл отвода из кессона продуктов травлени при подаче в кессон травильной жидкости. В качестве нейтрализующей жидкости в некоторых случа х может быть использована вода.The pipe 7 serves to drain pickle products from the caisson when the pickling fluid is supplied to the caisson. Water may be used as a neutralizing liquid in some cases.
