Description
Предметом изобретени вл етс приспособление к разрывным машинам дл определени предела прочности образцов резины, снабженное двум подвижными зажимами и шкалой удлинений.The subject of the invention is the adaptation to tensile machines for determining the tensile strength of rubber samples, equipped with two movable clamps and a scale of elongations.
Предлагаемое приспособление, по сравнению с известными устройствами подобного типа, вл етс более простым и обеспечивает большую точность измерени .The proposed device, in comparison with the known devices of this type, is simpler and provides greater measurement accuracy.
Ъсобенность приспособлени заключаетс в том, что в нем применена поперечна планка, жестко св занна с верхней т гой ма тникового динамометра и несуш,а по концам по одному блоку, а в центре - два блока; блоки охватываютс парой симметрично размешенных т говых тросиков, св зывающих подвижные зажимы с нижней т гой динамометра.The feature of the fixture is that it uses a transverse bar, rigidly connected with the upper thrust pendulum dynamometer and the floor, at the ends of one block, and in the center two blocks; The blocks are covered by a pair of symmetrically placed traction cables connecting the movable clips to the lower thrust dynamometer.
На чертеже изображена схема приспособлени .The drawing shows the arrangement.
Поперечна планка / жестко св зан а с верхней 2 ма тникового динамометра и снабжена двум подвижными зажимами 3 и 4.The crossbar / is rigidly connected with the upper 2-swing dynamometer and is equipped with two movable clamps 3 and 4.
На концах планки / укреплены блоки 5 и и вспомогательные блочки 7 н 8, а ъ средней части планки - два блока 9.At the ends of the plank /, blocks 5 and and auxiliary blocks 7 and 8 are strengthened, and in the middle part of the plank - two blocks 9.
Зажимы 3 и 4 двум симметричными тросиками, перекинутыми через блоки 5, 6 W. 9, св заны с нижней т гой 10 динамометра.Clips 3 and 4 are connected by two symmetrical cables, thrown over the blocks 5, 6 W. 9, connected to the lower tight 10 of the dynamometer.
Грузик //, подвешенный на тросике , перекинутом через блочок 7, воздействует на зажим 5, а грузик 12, подвешенный на тросике, перекинутом через блочок 8 - на зажим 4.The weight // suspended on a rope slung over block 7 acts on clip 5, and the weight 12 suspended on a rope slung over block 8 to clip 4.
Испытуемый образец 13 резины, имеюшей стандартную форму двусторонней лопатки, закрепл етс концами в зажимах 3 vi 4.The test specimen 13 of rubber, having the standard form of a double-sided blade, is fixed with the ends in the clips 3 vi 4.
Вначале испытани зажимы наход тс в сближенном положении и удерживаютс упорами 14 на заданном рассто нии, соответствуюшем длине недеформированного образца .At the outset of the test, the clamps are in a contiguous position and are held by the stops 14 at a predetermined distance corresponding to the length of the non-deformed sample.
На образец, кроме обычных меток 15 и 16, ограничиваюших длину рабочего участка, наноситс центральна отметка 17, котора On the sample, in addition to the usual marks 15 and 16, limiting the length of the working area, a central mark 17 is applied, which
