Description

Повышение качества от.пшок путем сообщени  жидкому металлу вибраций введением в него стержн , вибрирующего с числом колебаний от двух до ста тыс ч в минуту примен етс  на нрактике.Improving the quality of the flap by imparting vibrations to the liquid metal by introducing into it a rod vibrating with the number of vibrations from two to one hundred thousand hours per minute is applied in practice.

Однако при таком конетруктивном оформлеиии способ неудобей и не всегда позвол ет получать отливки желаемого качества.However, with such a design, the method is inconvenient and does not always allow to produce castings of the desired quality.

Предлагаемый способ устранени  гор чих усадочных трещин при кокильном литье цветных сплавов иутем применени  механической вибрации коки.ш удобен и прост в исполнении , позвол ет снизить литейный брак, расшир ет номенклатурчThe proposed method for eliminating hot shrinkage cracks in the chill casting of non-ferrous alloys and by using the mechanical vibration of coca. S is convenient and simple to perform, it allows to reduce the foundry scrap, expands the nomenclature

Способ отличаетс  тем, что, с целью улучшени  качества отливок, например, цилиндрической формы (поршней, втулок, цилиндров и др.), кокиль с кристаллизующейс  в нем отливкой с прибылью привод т в колебательное движенне с частотойThe method is characterized in that, in order to improve the quality of castings, for example, of a cylindrical shape (pistons, bushings, cylinders, etc.), a chill mold with a casting crystallizing in it with a profit leads to an oscillatory motion with frequency

Вибраци  люжет сообнлатьс  кокилю путем его установки на вибрационном столе и жесткого креплени  к последнему.Vibration sludge is communicated to the chill mold by mounting it on the vibrating table and rigidly fastening it to the latter.

Частота и амилитуда колебаний п указаииых пределах должна подбиратьс  экспериментально, применительно к каждой конкретно1( от ,111зке.The frequency and amilitude of the oscillations within the specified limits must be chosen experimentally, with reference to each concrete1 (from, zke).

Наилучшие ,1ьтаты достигаютс  при наличии запаса расплавленного металла, например, в виде прибыльной части отливки. При этом целесообразно, чтобы внбраци  была С(оби1,еиа коки.1ю еще до заполнени  его жидким металлом, продолжалась в процеесе всего лить  и закгшчнвалась лишь после полного затвердевани  отливки ц прибыли.The best, 1yaty are achieved in the presence of a stock of molten metal, for example, in the form of a profitable part of the casting. At the same time, it is advisable that the injection should be C (obi1, ei cocci.1y even before filling it with liquid metal, continued to be poured during the whole process and closed up only after the solidification of the casting and profit margins.
