Abstract
Изобретение относитс к устройствам дл коррозионных испытаний образцов под нагрузкой чистьш изгибом . Целью изобретени вл етс повышение точности при длительных испытани х под посто нной нагрузкой. Приспособление содержит две цилиндрические опоры в виде роликов 1 и один или несколько нажимных элементов , выполненных в виде вилки 3, жестко соединенного с полкой вилки 3 штока 4, охватывающей шток 4 втулки 5 с пружиной 6. Втулка 5 предназначена дл шарнирного соединени посредством роликов и направл ющей с сило- возбудителем. При воздействии на образец 14 нагрузки вилка 3 при на- гружении за счет пружины 6, котора предварительно оттарирована, обеспечивает плавное приложение нагрузки к образцу и поддерживает его посто нным в процессе испытаний. 2 ил. 9 СЛThis invention relates to devices for corrosion testing of samples under clean bending load. The aim of the invention is to improve the accuracy during long-term tests under constant load. The fixture contains two cylindrical supports in the form of rollers 1 and one or several pressure elements made in the form of fork 3 rigidly connected to the shelf of fork 3 of the stem 4, covering the stem 4 of sleeve 5 with spring 6. Sleeve 5 is designed for swiveling by means of rollers with force-causative agent. When a load is applied to the sample 14, the plug 3 when loaded by the spring 6, which is pre-tared, ensures a smooth application of the load to the sample and keeps it constant during the test. 2 Il. 9 SL

Изобретение относитс к испытательной технике, а именно к устройствам дл коррозионньпс испытаний образцов под нагрузкой.The invention relates to testing equipment, namely, devices for corrosion testing of samples under load.
Цель изобретени - повышение точ- ности при длительных испытани х под посто нной нагрузкой.The purpose of the invention is to improve the accuracy during long-term tests under constant load.
На фиг. 1 приведена схема устройства дл коррозионных испытаний с приспособлени ми дл нагружени чис- тым изгибом; на фиг. 2 - схема нажимного элемента с образцом.FIG. 1 shows a diagram of a device for corrosion testing with devices for loading with a clear bend; in fig. 2 - diagram of the pressure element with the sample.
Приспособление содержит две цилиндрические опоры в виде роликов 1 и 2 и один или несколько нажимных элементов, выполненных в виде вилки 3, жестко соединенного с полкой вилки 3 штока 4, охватывающей шток 4 втулки 5 с пружиной 6. Втулка 5 предназначена дл шарнирного соединени посредством роликов 7 и направл ющей 8с силово3будителем, выполненным в виде рычага 9 с грузом. Ролик 10 установлен между выступами вилки 3.The device contains two cylindrical supports in the form of rollers 1 and 2 and one or several pressure elements made in the form of a fork 3 rigidly connected to the flange of the fork 3 of the stem 4, covering the stem 4 of the sleeve 5 with the spring 6. The sleeve 5 is designed for swiveling by means of rollers 7 and the guide 8c by a power driver, made in the form of a lever 9 with a load. The roller 10 is mounted between the projections of the plug 3.
Устройство работает следующим об- разом.The device works as follows.
В чейку 11 устанавливают плиты 12 с полусферическими опорами 13, на которых размещают ролики 1 и 2.In the cell 11 install the plate 12 with hemispherical supports 13, on which are placed the rollers 1 and 2.

На ролики I и 2 устанавливают образец 14. Ячейки 11 с образцами 14 ус- танавливают в шахматном пор дке в термостате 15, Соедин ют втулки 5 с рычагами 9 и с помощью грузов 10 предают усилие на образцы. Вилка 3 при нагружении за счет пружины 6, котора предварительно оттарирована, обеспечивает плавное приложение нагрузки к образцу и поддерживает ее посто нной в процессе испытаний.Samples 14 are installed on rollers I and 2. Cells 11 with samples 14 are installed in a checkerboard pattern in a thermostat 15, Sleeves 5 are connected with levers 9 and, by means of weights 10, are applied to the samples. The fork 3, when loaded by the spring 6, which is pre-tared, ensures a smooth application of the load to the specimen and keeps it constant during the tests.
