УСТАНОВКА ДЛЯ ДИНАМИЧЕСКОГО РАСТЯЖЕНИЯINSTALLATION FOR DYNAMIC EXTENSION

Зз влено 30 но бр  1959 г. за № 645909/25 в Комитет по делам изобретени и открытий при Совете Министров СССР3 November 1959, No. 645909/25, to the Committee for Invention and Discovery under the Council of Ministers of the USSR

Опубликовано в «Бюллетене нзобретсииГ Л 16 за 1960 г.Published in the Bulletin of Inventions, L 16, 1960.

Установки дл  динамического 1)аст жони  металлов путем взрыва пороха в рабочем цилиндре известны. Однако в ннх обычно не предусмотрено силоизмерительное устройство, вследствие чего невозлюжно определение значе н  предела прочности и предела текучести металлов.Installations for dynamic 1) astronomy metals by exploding gunpowder in a working cylinder are known. However, a force-measuring device is not usually provided for in nanocomposites, as a result of which the determination of the value of the ultimate strength and the yield strength of metals is not absent.

Отличительна  особенность предложенной установки заключаетс  в том, что она снабжена силоизмерительным устройством в виде цилиндра с поргиенькол. Последний прижимаетс  калиброванной пружнной . к отверстию канала, соедин ющего рабочий ц)1линдр с силонз:.еритель ым .A distinctive feature of the proposed installation is that it is equipped with a force-measuring device in the form of a cylinder with a porgiecol. The latter is pressed against a calibrated spring. to the opening of the channel connecting the working cylinder to the cylinders: silo.

ЭтИМ достигаетс  возможность из геропи  усили , прикладываемото к раст гиваемому образцу.This is an opportunity to make an effort, applied to the sample to be stretched.

На чертеже изображена принципиальна  схема устаиовКи. В цилиндре / после взрыва дымного пороха создаетс  значительное давление газов в короткий промежуток времени. Пороховые газы оказызаот давление на поршень 2 и силоизмерительное устройство. Последнее состоит из поршенька 3, тарированиой пружины 4 н скобы 5, Зстановленных в корпусе 6.The drawing shows a schematic diagram of the setup. In the cylinder / after the black powder explosion a significant gas pressure is created in a short period of time. Powder gases exert pressure on the piston 2 and the load device. The latter consists of a piston 3, calibrating the spring 4 n brackets 5, fixed in the housing 6.

Поршень 2 выполнен за одно целое со штоком, в который ввертываетс  образец 7. Центрирование образца в верхней части обеспечир.аетс  сферической онорой 8, поко щейс  на траверсе .9. Дл  предупреждени  отскока образца носле разрыва П)едусмотрена крьпнка /(/также прикрепленна  к траверсе 9. Последн   прикреплена к трем ко;юннам //, выдержнвающдм основную нагрузку при испытании. Колочны // при испытании подвергаютс  кратковрелшнному сжатию, а траверса 9 - изгибу.The piston 2 is made in one piece with the rod into which sample 7 is screwed. The centering of the sample in the upper part is ensured by a spherical onor 8 resting on the traverse .9. In order to prevent the sample from rebounding when breaking the P), the mat / (/ is also attached to the yoke 9) is attached. The latter is attached to three teams; Yunn //, withstand the main load during the test.

Рабочий цилиндр / в нижней части имеет резьбу, посредством которой соедин етс  с основанием 12. Па боковой поверхности нижней части цилиндра 1 и верхней части основани  12 сделано восемь радиальных отверстий или окон 13, через которые при движении поршн  2 вниз выходит сжатый воздух. Через окна 13 также выход т пороховые газы, чем резко уменьшаетс  давление на рабочий поршень после разрушени  образца. Поршень, двига сь вниз, проходит мимо окон 13 и открывает выход пороховым газам в окружающую атмосферу.The working cylinder / in the lower part has a thread, through which it is connected to the base 12. Pa of the lateral surface of the lower part of the cylinder 1 and the upper part of the base 12 are eight radial holes or openings 13 through which compressed air flows down during the movement of the piston 2. Powder gases also escape through the windows 13, which sharply reduces the pressure on the working piston after the sample is destroyed. The piston, moving downward, passes by the windows 13 and opens the exit to the powder gases to the surrounding atmosphere.

В центре основани  12 просверлено осевое отверстие дл  дросселировани  воздуха и уменьшени  силы уда|)а поршн  о днище основанн . Давление воздуха после разрыва образца в нижней части cтaнoвкиAn axial hole is drilled in the center of the base 12 to choke air and reduce the piston removal force on the bottom of the base. Air pressure after rupture of the sample in the lower part of the installation
