Изобретение относитс к области испытаний материалов.This invention relates to the field of material testing.
Известен способ определени прочности материала , заключающийс Б том, что из материала издели вырезают стандартный образец и испытывают его на испытательных .A known method for determining the strength of a material is that a standard sample is cut out of the material of the product and is tested for testing.
Одна-ко при реализации этого способа необходимо вырезать образцы из конструкции дл исследовани ее прочностных свойств.However, when implementing this method, it is necessary to cut samples from the structure to study its strength properties.
Известен способ онределени -прочности материала , заключающийс в том, что выполл ют отверстие в испытуемом материале, нарезают резьбу, ввинчивают в отверстие нагружающий винт, вырывают его и при этом замер ют усилие среза и площадь срезаемой резьбы.A known method of determining the strength of a material is that a hole is made in the material under test, a thread is cut, a loading screw is screwed into the hole, the key is pulled out, and the cutting force and the area of the thread being cut are measured.
Этот способ вл етс наиболее близким к изобретению по технической сущности и достигаемому эффекту.This method is closest to the invention in its technical essence and the effect achieved.
Однако при ввинчивании стандартного винта в стандартную резьбу на неопределенное число (ВИТКОВ загружающее усилие распредел етс на витки как полного, так и неполного профил , а напр жени между витками распределены неравно:мерно, ори этом наиболее нагружены первый и последний витки.However, when screwing a standard screw into a standard thread for an indefinite number (WITCHES, the loading force is distributed over the coils of both the full and incomplete profile, and the stresses between the coils are unequally distributed: orientally, the first and the last coils are most loaded.
Предлагаемый способ отличаетс от известного тем, что с целью повышени точностиThe proposed method differs from that in that, in order to increase the accuracy
оцределени с резьбы отверсти и винта удал ют элементы непол1ного профил , а винт ввинчивают на целое число витков, не более двух. Изобретение по сн етс чертежом.The measurements from the thread of the hole and screw remove the elements of the incomplete profile, and the screw is screwed in by a whole number of turns, not more than two. The invention is illustrated in the drawing.
В испытуемом материале 1 высверливают отверстие 2 и нарезают в нем резьбу. Изготавливают нагружающий винт 3, затем удал ют с винта и отверсти элементы резьбы неполного профил , например, ввинчива винт в отверстие менее чем на один виток и вырыва его, оставл при этом резьбу полного профил . Далее ввинчивают винт на число витков не более двух и вырывают его, замер усилие вырыва. Площадь срезаемой резьбы посто нна и определ етс дпаметром резьбы и числом витков, которое оптимально равно одному или двум. Предлагаемый способ позвол ет с больщойIn the test material 1, drill a hole 2 and thread it. The loading screw 3 is made, then the elements of the thread of the incomplete profile are removed from the screw and the hole, for example, screwing the screw into the hole for less than one turn and tearing it out, leaving the thread for the full profile. Next, screw in the screw on the number of turns no more than two and pull it out, measuring the pull-out force. The area of the thread being cut is constant and is determined by the thread diameter and the number of turns, which is optimally equal to one or two. The proposed method allows with a large
точностью определ ть прочность материала.accuracy determine the strength of the material.
