Description

Насто щее изобретение касаетс  приспособлени  дл  испытани  материалов на изгиб, образцы которых выпOv Iнeны в виде балки, свободно лежащей на двух опорах.The present invention relates to a bend-testing apparatus, samples of which are made in the form of a beam, which lies loosely on two supports.

ОтличительнойособенностьюDistinctive feature

предлагаемого приспособлени   вл етс  применение .альной поддерживающей тр-аверсы, обеспечивающей исключение погрешностей от осадки образца на опорах.The proposed fixture is the use of a .alum supporting tr-obverse, ensuring the elimination of errors from precipitation of the sample on the supports.

На чертеже изображен общий вид предлагаемого приспособлени .The drawing shows a general view of the proposed fixture.

Индикатор 1, служащий дл  измерени  деформации, укрепл етс  на траверсе 5, снабженной трем  штифтами 2. Один из штифтов предназначен дл  установки траверсы 5 на стол 6 испытательного устройства , а два других, расположенные в плоскости индикаторной головки, вл ютс  опорными ножками, которые накладываютс  непосредственно на испытуемый образец 3. Игла 4 индикатора / располагаетс  посредине между штнфтам;и 2, а последние устанавливаютс  над опорами 7 образца 3.The indicator 1, which serves to measure the deformation, is fixed on the crosspiece 5, equipped with three pins 2. One of the pins is intended to set the crosshead 5 on the table 6 of the test device, and the other two, located in the plane of the indicator head, are supporting legs that overlap directly on the test sample 3. The needle 4 of the indicator / is located in the middle between the pins; and 2, and the latter are installed above the supports 7 of the sample 3.

При таком способе установки индикатора врезание и перемещение образца 3 на опорах 7, неизбежные при увеличении нагрузки, не оказывают никакого вли ни  н-а показа31With this method of installing the indicator, the plunging and moving of sample 3 on the supports 7, inevitable with increasing load, have no effect on the display 31

ВИЯ индикатора, поскольку при каких бы то ни было перемещени х образца- 3 леж.ащнй на нем индикакатор 1 перемещаетс  вместе с образцо .м. При этом игла 4 индикатора , представл юща  собой как бы третью свободную опору, отмечает совершенно точно прогиб испытуемого образца 3.The indicator's VIA, since during any movements of the sample - 3 lying on it, the indicator 1 moves along with the sample. At the same time, the needle 4 of the indicator, which is, as it were, the third free support, marks exactly the deflection of the test sample 3.

Прибор пригоден дл  определени  модул  упругости, остаточных и критических деформаций.The device is suitable for determining the modulus of elasticity, residual and critical deformations.

Предмет изобретени Subject invention

Приспособление к устройству дл  испытани  материалов на изгиб, образцы которых представл ют свободно лежащую на двух опорах балку, отличающеес  тем, что, с целью исключени  при измерени х погрешностей, обусловленных осадкой образца на опорах, оно выполнено в виде поддерживающей индикаторную головку или тому подобный инструмент траверсы с трем  установочными штифтами, один из которых предназначен дл  установки на стол устройства, а два других, расположенные в плоскости индикаторной головки, предназначены дл  установки на поверхности образиа над поддерживающим его опорами.Adaptation to the device for testing materials for bending, the samples of which represent a beam freely lying on two supports, characterized in that, in order to exclude errors in measurements due to the draft of the sample on the supports, it is made in the form of a supporting indicator head or the like crossheads with three mounting pins, one of which is intended for mounting on the table of the device, and the other two, located in the plane of the indicator head, are intended for mounting on the surface and form support for it.
