Description
Известен способ определени твердости материалов с помощью наблюдени величины погружени вдавливаемого в испытуемый материал шарика.There is a method for determining the hardness of materials by observing the amount of immersion of a ball pressed into the test material.
В предлагаемом приборе погружение шарика в испытуемый материал производитс помощью порохострельного приспособлени , в котором пулей вл етс упом нутый шарик.In the proposed device, the ball is immersed in the test material using a powder-cutting device, in which the bullet is the ball.
Изобра енный на прилагаемом чертеже в продольном разрезе прибор дл определени твердости материалов со :тоит из порохострельного приспособлени 1, установленного в днище стакана 2, прикладываемого открытым концом к испытуемому материалу; дл выхода образующихс при выстреле газов боковые стенки стакана снабжены сквозными отверсти ми.A device for determining the hardness of materials shown in the longitudinal section of the accompanying drawing is: Toit from a powder-cutting device 1, installed in the bottom of a glass 2, applied with an open end to the test material; The side walls of the glass are provided with through holes to escape the gases formed during firing.
Порохострельное приспособление .1 зар жают взрывчатым веществом 5 и в качестве пули примен ют стальной шаpjftt 4. Стакан 2 устанавливают на испытуемом материале, а ложе порохост| ельного приспособлени 1 опирают о плечо, после чего спускают курок ударника 6. По глубине проникани шарика 4 в испытуемый материал, что суд т о твердости последнего.The powder-cutting device .1 is charged with an explosive 5 and a steel balljet 4 is used as a bullet. Glass 2 is placed on the test material, and the powder bed | The working device 1 is supported on the shoulder, after which the hammer of the hammer 6 is pulled down. The depth of penetration of the ball 4 into the material under test is judged by the latter's hardness.
Предмет патента.The subject of the patent.
Прибор дл определени твердости материалов по величине пофужени шарика в испытуемый материал, характеризующийс применением, дл сообщени шарику определенной скорости, порохострельного приспособлени 1, установленного в днище стакана 2, снабженного отверсти ми в боковых стенках дл выхода газов и открытым концом прикладываемого к испытыемому материалу, пулей в каковом порохострельном приспособлении 1 вл етс вышеупом нутый шарик 4.A device for determining the hardness of materials according to the size of the ball poured into the test material, characterized by the application, to communicate a ball of a certain speed, to a powder-cutting device 1, installed in the bottom of a glass 2, provided with holes in the side walls to release gases and an open end applied to the material under test. in which the powder-cutting device 1 is the aforementioned ball 4.
