Description
До насто щего времени оправки дл навивки сеток с цилиндрическими или плоско-параллельными рабочими поверхност ми дл электронных ламп изготовл лись из дорогосто щих и дефицитных тугоплавких металлов, главным образом молибдена.Until now, mandrels for winding grids with cylindrical or plane-parallel working surfaces for electron tubes were made of expensive and scarce refractory metals, mainly molybdenum.
Преимуществом изобретени вл етс то, что оно позвол ет заменить дефицитные и дорогосто щие материалы, идущие на изготовление оцравки, боЛее дешевыми и упростить технологию изготовлени ее. Это достигаетс применением в качестве материала оправки керамики, например , высокоглиноземистой.An advantage of the invention is that it makes it possible to replace scarce and expensive materials used for the manufacture of sorts with more cheap ones and to simplify the technology of manufacturing them. This is achieved by using ceramics, for example, high alumina, as the mandrel material.
Процесс изготовлени керамических оправок заключаетс в литье массы в форму с последующим обжигом и щлифовкой.The process of making ceramic mandrels consists in casting the mass into a mold, followed by roasting and grinding.
Применение различных литьевых форм дает возможность получени оправок любых профилей, в зависимости от конфигурации сеточных каркасов.The use of various injection molds makes it possible to obtain mandrels of any profile, depending on the configuration of the grid frameworks.
Использование различной рецептуры керамики позвол ет получать оправки с температурным коэффициентом линейного расщирени (ТКЛР) в широком диапазоне, что дает возможность примен ть различные материалы каркасов сеток и навивочной проволоки, а также повышает качество сеток благодар дополнительному нат жению витков во врем пайки.The use of different ceramic formulations allows obtaining mandrels with a linear linear expansion coefficient (TCLE) over a wide range, which makes it possible to use various materials of wire mesh frames and coiling wire, as well as improves the quality of the grids due to the additional tension of the turns during brazing.
Применение керамики дл оправок нививки сеток снижает трудоемкость и себестоимость изделий, резко сокращает процент брака и повышает надежность в работе.The use of ceramics for grids of nivka nets reduces the complexity and cost of products, dramatically reduces the scrap rate and improves reliability in operation.
Предлагаемые керамические оправки дл навивки сеток могут быть, рекомендованы дл внедрени в электровакуумную промышленность;.,The proposed ceramic mandrels for winding nets can be recommended for introduction into the vacuum industry;.,
..Предмет изобретени .. The invention
Оправка дл навивки сеток с цилиндрическими или плоско-параллельными рабочими поверхност ми дл электронных ламп, отличаю№ 150944- 2 ща с тем, что, с целью замены дефицитных тугоплавких металлов, идущихна изготовление оправки, и упрощени технологии ее изготовлени , в,качестве материала оправки применена керамика, например, БЫСокоглиноземиста .Mandrel for winding grids with cylindrical or plane-parallel working surfaces for electron tubes, characterized by the number 150944-2, with the aim of replacing the scarce refractory metals going into the manufacture of the mandrel, and simplifying the technology of its manufacture, as the mandrel material applied ceramics, for example, by high alumina.
