Description

Существующие способы испытаний механических свойств лить  предусматривают применение образцов, подвергнутых об зательной механической обработке, что св зано с затратой времени, труда и средств на их механическую обработку.The existing methods for testing mechanical properties of casting involve the use of samples subjected to mandatory machining, which is associated with the expenditure of time, labor, and funds for their mechanical processing.

Описываемые литые и ударные образцы дл  определени  механических свойств лить  по выплавл емым модел м могут подвергатьс  испытани м без предварительной механической обработки. Это достигаетс  тем, что описываемые образцы обладают гладкой без литейных пороков поверхностью и плотной структурой, что удаетс  обеспечить благодар  уменьшению длины образца, удачному выбору соотношений его размеров , а также приданием конусности нерабочим част м образца. Образцы отливаютс  по выплавл емым модел м и примен ютс  без механической обработки.The described cast and impact specimens for determining the mechanical properties of the casting according to melted models can be subjected to tests without prior mechanical processing. This is achieved by the fact that the samples described have a smooth surface without a casting defect and a dense structure, which can be achieved by reducing the length of the sample, successfully selecting its size ratios, and also giving the non-working parts taper. Samples are molded on melted models and applied without machining.

Ударные образцы (см. чертеж, поз. а) отливаютс  с литейными откосами с боков высотой 2-3 мм на сторону, причем в центральной части образца на стороне, не имеюшей откосов, вырезаетс  канавка, глубиной 2 мм. Рабочее сечение образца 10 X Ю Impact specimens (see drawing, pos. A) are cast with casting slopes from sides 2-3 mm high to the side, and in the central part of the sample on the side that does not have slopes, a groove is cut 2 mm deep. The working section of the sample 10 X Yu

Образец дл  испытаний на разрыв (см. чертеж, поз. б) имеет укороченную рабочую длину, не превышающую одного-двух его диаметров, причем нерабоча  его часть выполн етс  конической формы.The tensile test specimen (see drawing, pos. B) has a shortened working length not exceeding one or two diameters, and its non-working part is conical in shape.

Предмет изобретени Subject invention

1. Литые разрывные и ударные образцы дл  определени  механических свойств лить  по выплавл емым модел м, отличающиес 1. Cast rupture and impact specimens for determining mechanical properties of casting according to melted models, different

тем, что, с целью получени  плотной структуры металла литого образца , расчетную длину разрывного образца делают длиной в один-два его диаметра.By the fact that, in order to obtain a dense structure of the metal of the cast sample, the calculated length of the discontinuous sample is made one or two times its diameter.

2. Форма выполнени  ударного об;разца пол. 1, отличающа с  тем, что, с целью уплотнени  металла в рабочем сечении надреза, нерабочую часть образца выполн ют конической формы.2. The form of execution of the shock about; 1, characterized in that, in order to seal the metal in the working section of the notch, the non-working part of the sample is conical.
