Description
(54) СПОСОБ ИСПЬЛТАНИЯ НА РАСТЯЖЕНИЕ ПЛОСКИХ ОБРАЗЦОВ(54) METHOD FOR EXTENDING THE EXTENSION OF FLAT SAMPLES
Кроме того, с целью фиксировани в камере разрушенных образцов, на боковых сзюверхност х пальцев выполн ют симметричные сегментные срезыIn addition, in order to fix the destroyed specimens in the chamber, symmetric segment sections are made on the lateral surfaces of the toes.
На фиг. 1 представлено устройство дл реализации способа} на . фиг. 2 - разрез А-А на, фиг. 1.FIG. 1 shows a device for implementing the method} on. FIG. 2 is a section A-A on FIG. one.
Устройство оодержит герметичную камеру 1 с отверсти ми 2 дл ввода рабочей среды, захваты 3 и 4 с палцами 5 и 6, на которых устанавливаютс образцы 7 с разной высотой головок 8-10 и отверсти ми 11 пр моугольной формы. Внутренние поверхности 12 отверстий, взаимодействующие с пальцами. 5 и 6, выполнены в виде призм, а поверхности пальцев с ответными подушками 13 и 14. На боковых поверхност х пальцев выполнены симметричные сегментные срезы 15 и 16.The device contains a sealed chamber 1 with holes 2 for entering the working medium, grippers 3 and 4 with rods 5 and 6, on which samples 7 with different heights of heads 8-10 and holes 11 of rectangular shape are mounted. The inner surface of the 12 holes interacting with the fingers. 5 and 6 are made in the form of prisms, and the surfaces of the fingers with counter pads 13 and 14. Symmetric segment sections 15 and 16 are made on the side surfaces of the fingers.
Способ.осуществл етс следующим образом.The method is carried out as follows.
При нагружении образец с самой короткой головкой 8, перемеща сь по наклонным плоскост м подушек 13 и 14 пальцев 5 и 6, автоматически устанавливаетс по оси раст гивающей нагрузки. В это врем остальные образцы свободно вис т на верхнем пальце 5, так как между пальцем б и поверхност ми 12 призм нижних головок образцов имеетс зазор, величина которого позвол ет деформировать испытываемый образец вплоть до его разрушени . После разрыва первого образца его разрушенные части, отодвигаютс , влево следующим образом с головками 9, которые при нагружении устанавливаютс призмами 12 на подушки 13 и 14 пальцев по оси раст гивающей нагрузки и т.дWhen loading, the sample with the shortest head 8, moving along the inclined planes of the pads 13 and 14 of the fingers 5 and 6, is automatically installed along the axis of the tensile load. At this time, the remaining samples hang freely on the upper finger 5, since there is a gap between the finger b and the prism surfaces 12 of the lower heads of the samples, the magnitude of which allows the sample to be deformed up to its destruction. After breaking the first sample, its destroyed parts are moved aside, to the left, with heads 9, which are loaded with prisms 12 onto pillows 13 and 14 of the fingers along the tensile load axis, etc.
Данный способ значительно снижает трудоемкость разборки-сборки устройства и замены образцов при испытании .This method significantly reduces the complexity of the disassembly-assembly of the device and the replacement of samples during testing.
