Description
;54) УСТАНОВКА ДЛЯ ПРОЧНОСТНЫХ ИСПЫТАНИЙ МАТЕРИАЛОВ; 54) INSTALLATION FOR STRONG TESTS MATERIALS
помощью осей 15 и 16 и с т гами 5 и 6, и два кривошипа 17 и 18, имеющие длину, равную половине длины шатунов 13 и 14, и шарнирно соединенные одними своими концами с опорной рамой 1, а другими - с серединами шатунов 13 и 14. Приводной винт 8 соединен с приводом 7 с помощью зубчатых колес 19 и 20. Опорный штамп 4 выполне в виде цилиндра с проушиной 21, в которую запрессована ось 22, взаимодействующа с упругим параллелограмом 23 силойзмерител . Образец 24 материала размещают между подвижной и неподвижной траверсами 2 и 3. При испытани х на сжатие на подвижную траверсу устанавливаетс с помощью полусферического шарнира нагружающий штамп (на чертеже не показан) . При испытани х на изгиб нагружающий штамп выполн ют в виде рамки 25, которую при помощи пружин 26 и 27 и опорных пластин 28 и 29 устанавливают на требуемой высоте в опорных пазах 30-32, выполненных в т гах 5 и 6, и цилиндрических ножей 33 и 34. Установка работает следующим образом .using axles 15 and 16 and with tgami 5 and 6, and two cranks 17 and 18, having a length equal to half the length of the rods 13 and 14, and pivotally connected to one end with the supporting frame 1, and the other with the middle of the rods 13 and 14. The drive screw 8 is connected to the drive 7 by means of gear wheels 19 and 20. The supporting stamp 4 is made in the form of a cylinder with an eye 21, into which an axis 22 is pressed, interacting with an elastic parallelogram 23 of a power meter. A material sample 24 is placed between the movable and stationary cross braces 2 and 3. During compression tests on the mobile cross bar, a loading stamp (not shown) is installed using a hemispherical hinge. In bending tests, the loading stamp is made in the form of a frame 25, which with the help of springs 26 and 27 and supporting plates 28 and 29 is installed at the required height in the supporting grooves 30-32, made in bars 5 and 6, and cylindrical knives 33 and 34. The installation works as follows.
Устанавливают втулки 11 и 12 таки образом, чтобы концы т г 5 и 6 находились на одинаковой высоте. После включени привода 7 через зубчатые колеса 19 и 20 привод т во вращение приводной винт В, в результате чего втулки 11 и 12 получают поступательное горизонтальное перемещение в разные стороны, что сообщает вертикальное перемещение вверх передаточным плечам шатунов 13 и 14, а через них т гам 5 и 6 и подвижной траверсе 2. Нагрузка через нагружающий штамп передаетс на образец 24, а через опорный штамп 4 на упругий параллелограмм 23 силоизмерител , который фиксирует усилие, действующее на образец при его сжатии или изгибе .Install the sleeves 11 and 12 in such a way that the ends of m, g 5 and 6 are at the same height. After actuating drive 7 through gears 19 and 20, drive screw B rotates, causing sleeves 11 and 12 to receive translational horizontal movement in opposite directions, which indicates vertical movement upward of the connecting rods of connecting rods 13 and 14, and through them 5 and 6 and movable cross bar 2. The load is transmitted to the sample 24 through the loading stamp, and through the supporting stamp 4 to the elastic parallelogram 23 of the load cell, which captures the force acting on the sample during its compression or bending.
При этом нагрузка на образец передаетс строго центрировано, поскольку отсутствуют перекосы подвижной траверсы.In this case, the load on the sample is transmitted strictly centered, since there are no distortions of the moving beam.
