Description
Известные устройства дл определени работы деформации раст жени не дают достаточно точното п; едставлени о характере деформации , вследствие необходимости построени кривых раст жени по точкам .The known devices for determining the work of the tensile deformation do not provide sufficient accuracy of n; of the nature of the deformation, due to the need to construct tensile curves by points.
Описываемое устройство к ма тниковому копру дл определени работы деформации раст жени , например, высокомолекул рных материалов позвол ет повысить точность измерени . Это достигаетс тем, что в устройстве применены две динамометрические прулсины, консольио закрепленные в опорах и имеющие на свободных концах зажимы дл образца, передающего усилие ма тника через пружины на датчики сопротивлени , вход щие в измерительную систему, импульс которой фиксируетс на осциллограмме, переводимой затем в диаграмму раст жени .The described tilting device for determining the work of stretching deformation, for example, of high molecular weight materials, makes it possible to increase the measurement accuracy. This is achieved by using two dynamometric prulsins in the device, mounted in supports and having clamps on the free ends for the sample, transmitting the pendulum through the springs to the resistance sensors included in the measuring system, the pulse of which is recorded on the oscillogram, then transferred to stretch chart.
На чертеже изображена схема устройства.The drawing shows a diagram of the device.
Медведка / (часть ма тникового копра) св зана с осью 2, установленной на стойках 3. К станине копра прикреплены опоры 4, на которых консольно закреплены две динамометрические пружины 5 при помощи fiaкладок 6. На пружинах 5 имеютс датчики 7 сопротивлени , вход щие в измерительную схему, включающую в себ усилитель 8 и осциллограф 9. На свободных концах пружины 5 снабжены зажил{амн 10 дл испытуемого образца П. Дл испытани м гких образцов (резины и резиновых изделий) применен компенсирующий валик 12 н щечки 13, прикрепленные к стойкам 3.The Medvedka / (part of a tiller copra) is connected to an axis 2 mounted on racks 3. Supports 4 are attached to the copra frame, on which are supported two two dynamometric springs 5 cantilevered using fia-tabs 6. On the springs 5 there are resistance sensors 7 that are included in a measuring circuit including an amplifier 8 and an oscilloscope 9. At the free ends of the spring 5 are supplied healed {amn 10 for the test sample P. For testing soft samples (rubber and rubber products), a compensating roller 12 n cheeks 13 attached to racks 3 .
Испытуемые образцы изготавливаютс различных видов, например дл эбонита - пр моугольные бруски, дл резины - концы. При испытании твердых материалов (эбонит) используют один образец, который укладываетс в зажимы динамометрической пружины. Дл испытани м гких материалов (резина) берут одновременно два образца (кольца).The test specimens are made of various kinds, for example for ebonite - rectangular bars, for rubber - the ends. When testing solid materials (ebonite), one specimen is used, which is placed in the clamps of a torque spring. For testing soft materials (rubber), two samples (rings) are taken simultaneously.
