Description

жена устройством качани  8, выполненным в частности, в виде кривошипно-шатунного механизма.. Муфель снабжен раздвижным поддоном 9.the wife is a swinging device 8, made in particular in the form of a crank mechanism. The muffle is provided with a sliding tray 9.

Рельсы взоне перекатывани  каждого катка тележки при ее качании вьшолнены вогнутыми по радиусу, величина которого равна длине ма тника с собственной часто той качани , равной частоте качани  тележки . Пунктиром показано положение тележки с подложкой в период подготовки печв к плавке в сн ти  наплавленного де и .The rails on the rolls of each roller of the trolley when it is swinging are concave radially, the value of which is equal to the length of the tandem with its own frequency of swing, equal to the frequency of swing of the cart. The dotted line shows the position of the carriage with the substrate during the preparation of the furnaces for smelting in the removal of the deposited metal.

Дл  наплавлени  издели  тележку с подложкой подают под муфель и соедин ют с устройством качани . Затем, .- раздвинув поддон муфел , подложку вертикальным перемещением ввод т в муфель так, чтобы поверхность подложки находилась в фокусе горелки (фокусное рассто ние на чертеже обозначено И ). Закрывают поддон, включают приводы вращени  подложки и качани  тележки с подложкой, подают гор чую смесь в горелку и поджигают ее.To weld the product, the carriage with the substrate is fed under the muffle and connected to a swing device. Then, by extending the muffle pan, the substrate is vertically moved into the muffle so that the substrate surface is at the burner focus (the focal distance in the drawing is marked AND). The pan is closed, the substrate rotational drives and the trolley with the substrate are turned on, the hot mixture is fed into the burner and set on fire.

После разогрева п тна наплавлени  до температуры плавлени  кварца начинают подачу кварцевой крупки через центральный канал горелки. Вращение и качание подложки обеспечивает увеличение площади п тна наплавлени , выравнивание температуры поверхности п тна и рассыпание крупки по поверхности наплавлени . Наплавление изделий диаметоом больше, чем диаметр п тна наплавлени , обеспечиваетс  за счет растекани  расплава , при Этом поверхность издели  получаетс  выпуклой. Положение центральной части издели  в фокусе горелки по мере наплавлени  издели  достигаетс  путем постепенного опускани  подложки.After heating the spot of fusing to the melting point of quartz, the quartz grit starts to flow through the central channel of the burner. Rotation and oscillation of the substrate provides an increase in the area of the weld spot, the alignment of the temperature of the spot surface and the scattering of the grains over the weld surface. The fusion of products with a diameter greater than the diameter of the spot of fusion is ensured by the spreading of the melt, at which the surface of the product turns out to be convex. The position of the central part of the product in the burner focus as the product is fusing is achieved by gradually lowering the substrate.

В предложенной конструкции при перекатывании тележки по вогйутым поверхност м рельсов сохран етс  положение всех точек, поверхности п тна наплавлени  в фокусе горелки за счет соответствующего плоско-параллельного перемещени  тележкиIn the proposed construction, when rolling the carriage over the possible surfaces of the rails, the position of all points, the spot welding surface at the burner focus, is maintained due to the corresponding plane-parallel movement of the carriage

с подложкой вверх при смещении тележки в ту или иную сторону от центра качани . Благодар  стабилизации положени  поверхности наплавлени  относительно фокуса горелки улучшаетс  качество наплавл емыхwith the substrate up when the trolley is moved to one side or the other from the center of swing. By stabilizing the position of the weld surface relative to the burner focus, the quality of the welds is improved.

В предлагаемой конструкции печи при возвратно-поступа тельном перекатывании тележки по вогнутым рельсам с частотой,In the proposed design of the furnace when the reciprocating rolling carts on concave rails with a frequency of

равной собственной частоте качани  ма тника , вследствие плоско-параллельного перемещени  всех точек тележки, подложки и изде и  исключаетс  вли ние инерционньтх сил на основание подложки,equal to the natural frequency of the swing of the tang, due to the plane-parallel movement of all points of the carriage, the substrate and the product, and the influence of inertial forces on the substrate base is eliminated,
