Изобретение относитс к измерительной технике, и именно к средствам дл оценки физике-механических свойств частиц и гранул, например в порошковой металлургии.The invention relates to a measurement technique, and specifically to means for evaluating the physicomechanical properties of particles and granules, for example in powder metallurgy.
Известны устройства дл определени фактической площади касани образцов под нагрузкой, содержащие узел нагружени , узел измерени относительного смещени образцов и узел измерени площади их взаимного касани ij.Devices are known for determining the actual area of contact of samples under load, comprising a loading unit, a unit for measuring the relative displacement of samples, and a unit for measuring the area of their mutual contact ij.
Недостатком данных устройств вл етс то, что они могут быть использованы только дл измерени площадей касани образцов и непригодны дл исследовани свойств материалов, состо щих из отдельных частиц и гранул.The disadvantage of these devices is that they can only be used to measure the areas of contact of the samples and are unsuitable for studying the properties of materials consisting of individual particles and granules.
Известно также устройство дл О1ределени фактической плошади каса1ШЯ , содержащее нагружающий механизм с верхним прозрачным и нижним непрозрачным пуансонами, узел измерени относительного перемещешт пуансонов и узел измерени плошади касани It is also known a device for determining the actual area of the cassette, comprising a loading mechanism with upper transparent and lower opaque punches, a relative measuring unit displacing the punches and a touching square measuring unit.
контролируемых частиц с BOJIXHHM пуансоном . Верхний пуансон выполнен в виде призмы полного внутреннего отражени , а узел измерени относительного смещени пуансонов размещен на механизме нагружени t2jl.controlled particles with a BOJIXHHM punch. The upper punch is made in the form of a prism of total internal reflection, and the unit for measuring the relative displacement of the punches is placed on the loading mechanism t2jl.
Недостатком таких устройств вл етс недостаточна точность вследствие деформации механизма нагружени верхнего хфозрачного пуансона, который вл етс несимметричным и неравножестким в различных част х рабочей зоны.The disadvantage of such devices is the lack of accuracy due to the deformation of the loading mechanism of the upper cold punch, which is asymmetrical and unequal in different parts of the working area.
Цель изобретени - повышение точности .The purpose of the invention is to improve accuracy.
Указанна цель достигаетс тем, что верхний пуансон выполнен в виде оправы с равномерно расположенными смоrpoBbiMH окнами и пррзрачного диска, перекрывающего эти окна, а узел .This goal is achieved by the fact that the upper punch is made in the form of a frame with evenly spaced cmpoBbiMH windows and a transparent disk overlapping these windows and a node.
измерени относнгельного смещени пуансонов закреплен на нижнем пуансоне и размещен симметрично относительно центров смотровых окон.measurements of the relative displacement of the punches are fixed on the lower punch and positioned symmetrically with respect to the centers of the viewing windows.
