Description

В современной технике, особенио электровакуумной, широко примен ютс  керамнчбские муфели круглого сечени , имеющие на наружной поверхности «арезку дл  размещени  в ней электронагревательного элемента (проволоки, ленты и пр.). Преимущество указанных муфелей (с резьбой по наружной поверхности) по сравнению с обычными гладкостеннымн очевидно. Однако получение резьбы на наружной поверхности муфел  св зано со значительными трудност ми .In modern technology, especially electrovacuum, keramnchbskie muffles of circular cross-section are widely used, having a cut-out on the outer surface for placing an electric heating element (wire, tape, etc.) in it. The advantage of these muffles (threaded on the outer surface) compared to conventional smooth-walled is obvious. However, obtaining a thread on the outer surface of the muffle is associated with considerable difficulties.

Формовка муфел  с резьбой приводит к растрескиванию его во врем  обжига или же «е обеспечивает необходимой ллотности керамики.Molding a muffle with thread leads to cracking it during firing, or “e provides the necessary density of ceramics.

Механическа  обработка обожженных муфелей, в частности нарезание на них резьбы, требует много времени, больщого количества абразивов , а главное не обеспечивает получени  необходимого качества издели  из-за сн ти  наружной корки муфел .Mechanical treatment of burnt muffles, in particular, threading them, requires a lot of time, a large number of abrasives, and most importantly does not ensure the required quality of the product due to the removal of the muffle outer crust.

Механическа  обработка необожженных муфельных заготовок на вводимых в них оправках, зажимаемых в патроне станка, может быть применена только к трубам малых габаритов.Mechanical processing of unfired muffle blanks on mandrels inserted into them, clamped in the machine chuck, can only be applied to pipes of small dimensions.

Изобретение имеет целью обеспечить возмож ность осуществлени  механической обработки необожженных керамических муфельных заготовок на вводимых в них оправках дл  получени  на наружной поверхности муфел  углублений, резьбы, канавок, а также дл  придани  стенкам муфел  определенной толщины и формы .The invention is intended to enable the machining of unfired ceramic muffle blanks on the mandrels inserted therein in order to obtain recesses, threads and grooves on the outer surface of the muffle, as well as to give the muffle walls a certain thickness and shape.

Это достигаетс  путем закреплени  необожнсенной керамической (алз-ндовой, щамотной и нр.) муфельной заготовки на валу перед ее механической обработкой с помощью вводимой в заготовку оправки-втулки , соедин емой с валом посредством легкоплавкого материала, и заЯОЛН6НМЯ внутренного пространства заготовки сыпучим материалом, например , мелко раздробленными кусками обожженной керамики.This is achieved by fixing an empty ceramic (Al-Nd, Shamotn and nr.) Muffle billet on the shaft before machining it using a mandrel-bushing inserted into the workpiece with a low-melting material, and SUBSTITUTING the internal space of the billet bulk material, for example , finely crushed pieces of baked ceramics.

На фиг. представлена в продольном разрезе муфельна  заготовка , закрепленна  на оправке; на фиг. 2 - вид оправки с торца; на фиг. 3 .- продольный разрез оправки.FIG. presented in the longitudinal section of a muffle blank, mounted on a mandrel; in fig. 2 - view of the mandrel from the end; in fig. 3 .- longitudinal section of the mandrel.

Весь процесс изготовлени  муфелей заключаетс  в следующем.The whole process of making muffles is as follows.

Обычным путем из керамической массы (алундовой, щамотной и пр.) формуетс  и сущитс  муфельна  заготовка / с некоторым припуском по наружному диаметру.In the usual way, the ceramic mass (alundum, ground metal, etc.) is molded and the muffle billet is prepared / with some allowance for the outer diameter.
