Description
Известны приборы дл измерени деформаций образцов при их поперечном изгибе на разрывной машине.Instruments are known for measuring sample deformations during their transverse bending on a tensile machine.
Описываемый прибор отличаетс от известных приборов того же назначени применением двух установленных в зажимах разрывной машины траверс, кажда из которых имеет два р да отверстий, предназначенных дл креплени в них переставных планок, снабженных на свободных концах опорными роликами, служащими дл захвата между ними испытуемого образца. Опорные ролики выполнены составными из р да отдельных колец, одно из которых снабжено зажимом дл фиксации положени плоскости образца, а другое - рифленой поверхностью, с целью определени углов наклона оси изгибаемого образца на опорах.The described device differs from the known devices of the same designation by using two traverses installed in the clamps of the tensile testing machine, each of which has two rows of holes designed to fasten the adjustable strips in them equipped with supporting rollers at their free ends to grip the test sample between them. The support rollers are made up of a series of individual rings, one of which is provided with a clamp to fix the position of the sample plane, and the other with a grooved surface, in order to determine the angle of inclination of the axis of the bendable sample on the supports.
На фиг. 1 изображен обш.ий вид прибора в двух проекци х; на фиг. 2 - устройство опорных роликов.FIG. 1 shows a general view of the device in two projections; in fig. 2 - the device of basic rollers.
Прибор состоит из двух траверс 1, кажда из которых имеет два р да отверстий 2 с одинаковыми рассто ни ми между их центрами. На траверсах / жестко креп тс болтами в соответствующих отверсти х 2 переставные планки 3; кажда планка 3 на свободном конце снабжена валиком, с надетым на него опорным роликом 4. Траверсы 1 захватываютс в своих вершинах зажимами 5 разрывной машины. Дл измерени деформаций образца на траверсе 1 укрепл ютс индикатор 6 и прогибомеры 7. Дл св зи прогибомеров 7 нит ми или струнами 8 применены ролики 9 переставных пластин 10, устанавливаемых в соответствующих отверсти х траверсы /.The device consists of two traverses 1, each of which has two rows of holes 2 with the same distances between their centers. On traverses / rigidly fastened with bolts in the corresponding holes x 2 adjustable strips 3; each strip 3 at the free end is provided with a roller, with a supporting roller 4 mounted on it. Traverses 1 are gripped in their tops by the clips 5 of the bursting machine. To measure the deformations of the specimen on traverse 1, indicator 6 and defibomers 7 are strengthened. For the connection of defibomers 7 yarns or strings 8, rollers 9 of adjustable plates 10 are used, installed in the corresponding traverse holes /.
На изгибаемом образце 11, сверху, снизу и сбоку, в зависимости от необходимости, устанавливаютс тензометры. Дл измерени углов наклона оси образца // и приращени длины крайних раст нутых волокон образца при изгибе опорные ролики выполнены составными из колец 12, 13 и 14 (фиг. 2). Кольцо 12 снабжено опорной площадкой тп, служащей дл фиксации положени плоскости образца. Кольцо 13 вл етс промежуточным и снабжено проточкой S дл пропуска струны 8 к прогибемеру . Кольцо 14 снабжено рифленой поверхностью. Во избежание трени одного кольца о другое они разделены шайбами 15. К кольцам 12 иOn the bendable specimen 11, strain gauges are installed on top, bottom and side, depending on the need. To measure the angle of inclination of the sample axis // and increment the length of the extreme stretched sample fibers during bending, the support rollers are made of rings 12, 13, and 14 (Fig. 2). The ring 12 is provided with a support platform tp serving to fix the position of the sample plane. The ring 13 is intermediate and provided with a groove S for passing the string 8 to the deflector. The ring 14 is provided with a grooved surface. In order to avoid friction of one ring about another, they are separated by washers 15. To rings 12 and
