Abstract
Изобретение относитс к машиностроению и предназначено дл термообработки стальных изделий в жидкой охлаждающей среде. Цель изобретени - интенсификаци и повышение качества закалки при снижении энергозатрат и расширение области применени закалочных сред. Устройство содержит бак 1 с установленным в нем диспергатором 2. Диспергатор выполнен в виде сопла Лавал 3, закрепленного в шаровом шарнире 4. На торце сопла соосно с ним закреплен цилиндрический патрубок 5, при этом между его внутренней поверхностью и наружной поверхностью сопла 3 образована кольцева щель 6. Длина патрубка 5 составл ет 8 - 12 его внутренних диаметров. Сопло 3 трубопроводом 7 через переключатель 8 соединено с баллоном сжатого газа 9. Переключатель св зан с управл ющим блоком 10. 1 ил.The invention relates to mechanical engineering and is intended for the heat treatment of steel products in a liquid cooling medium. The purpose of the invention is to intensify and improve the quality of quenching while reducing energy consumption and expanding the field of application of quenching media. The device contains a tank 1 with a disperser 2 installed in it. The disperser is made in the form of a Laval nozzle 3 fixed in a ball joint 4. A cylindrical nozzle 5 is fixed coaxially with it at the end of the nozzle, with an annular gap between its inner surface and the outer surface of the nozzle 3 6. The length of the nozzle 5 is 8 to 12 of its internal diameter. The nozzle 3 by pipe 7 is connected via a switch 8 to a compressed gas cylinder 9. The switch is connected to the control unit 10. 1 sludge.

На чертеже показано устройство, общий вид.The drawing shows the device, a general view.
Устройство содержит бак 1, в котором установлен диспергатор 2. Дис- пергатор выполнен в виде сопла Лава- л 3, которое закреплено на баке 1 в шаровом шарнире 4. На выходном торце сопла соосно с ним закреплен цилиндрический патрубок 5, при этом между его внутренней поверхностью и наружной поверхностью сопла 3 образован кольцевой зазор 6, Длина патрубка 5 с оставл ет .8-12 его внутренних диаметров. Сопло 3 трубопроводом 7 через переключатель 8 соединено с баллоном сжатого газа 9. Переключатель 8 св зан с программным управлением блоком 10„The device contains a tank 1 in which a disperser 2 is installed. The disperser is made in the form of a Laval nozzle 3, which is fixed to the tank 1 in a ball joint 4. At the nozzle exit end, a cylindrical nozzle 5 is fixed coaxially with it the annular gap 6 is formed by the surface and the outer surface of the nozzle 3, the length of the nozzle 5 seconds leaving .8-12 its internal diameters. The nozzle 3 is connected by a pipeline 7 through a switch 8 to a compressed gas cylinder 9. A switch 8 is connected with a program control unit 10 "
Устройство работает следующим образом ,,The device works as follows,
В закалочный бак 1 заливают охлаждающую среду (масло, раствор полимеров , минеральных солей). К сверхзвуковому соплу 3 от баллона 9 при открытом переключателе 8 подают сжатый газ. Истека из сверхзвукового сопла 3, газ диспергируетс в эжекти руемую в патрубок 5 охлаждающую жидкость и в виде свободной затопленной газожидкостной струи направл етс на обрабатываемую деталь. По соответствующей команде, сформулированной блоA cooling medium (oil, solution of polymers, mineral salts) is poured into the quenching tank 1. A compressed gas is supplied to the supersonic nozzle 3 from the cylinder 9 with the switch 8 open. After expiration of the supersonic nozzle 3, the gas is dispersed into the cooling liquid ejected into the nozzle 5 and, in the form of a free submerged gas-liquid jet, is directed to the workpiece. According to the appropriate team formulated blo

ком 10, переключатель 8 отсекает подачу сжатого газа к сверхзвуковому соплу 3. Процесс повтор етс с частотой 0-10 Гцcom 10, switch 8 cuts off the flow of compressed gas to the supersonic nozzle 3. The process repeats at a frequency of 0-10 Hz
Использование предлагаемого устройства позвол ет повысить качество обработанных изделий, уменьшить процент брака, повысить производительность оборудовани . Расшир етс область применени конкретной закалочной среды, представл етс возможность замены ее на более дешевую, по вл етс возможность регулировани охлаждающей способности закалочных сред в широком диапазоне от масла до воды Предлагаемое устройство имеет незначительные габариты, надежно в работе, удобно в обслуживании.The use of the proposed device allows improving the quality of the processed products, reducing the scrap rate, and increasing the productivity of the equipment. The field of application of a specific quenching medium is expanded, it can be replaced with a cheaper one, it becomes possible to control the cooling capacity of quenching media in a wide range from oil to water. The proposed device has small dimensions, is reliable in operation, and is convenient to maintain.
