Description
Известен способ определения механических характеристик проволоки ГОСТ 2246-70, ГОСТ 10446-80, ГОСТ 1497-84 (Методы испытания на растяжение). A known method for determining the mechanical characteristics of the wire GOST 2246-70, GOST 10446-80, GOST 1497-84 (Tensile test methods).
Недостатками известных способов являются:
1) наличие проскальзования захвата проволоки при растягивания образца на разрывной машине и наличие контактных напряжений на образце, что снижает точность и надежность полученных результатов испытаний;
2) необходимость иметь дорогостоящее оборудование (пресса) и высококвалифицированные кадры испытателей и специальных лабораторий;
3) невозможность контролировать качество проволоки в процессе ее изготовления (проката), что не исключает вероятность брака.The disadvantages of the known methods are:
1) the presence of wire gripping slippage during stretching of the sample on a tensile testing machine and the presence of contact stresses on the sample, which reduces the accuracy and reliability of the test results;
2) the need to have expensive equipment (press) and highly qualified personnel of testers and special laboratories;
3) the inability to control the quality of the wire in the process of its manufacture (rental), which does not exclude the possibility of marriage.
Цель изобретения - увеличение точности испытаний и надежности получаемых результатов, а также снижение ее стоимости. The purpose of the invention is to increase the accuracy of tests and the reliability of the results, as well as reducing its cost.
Поставленная цель достигается тем, что проволоку деформируют между двумя инденторами клинообразной формы с углом прострения 120 градусов по радиусу проволоки (поперек) дискретно увеличивающейся нагрузкой, прикладываемой в разные точки по длине образца. This goal is achieved in that the wire is deformed between two wedge-shaped indenters with a cutting angle of 120 degrees along the radius of the wire (across) a discretely increasing load applied at different points along the length of the sample.
Способ осуществляется следующим образом. The method is as follows.
Индентором клинообразной формы ударяют по радиусу проволоки, расположенной на основании также клинообразной формы с дискретно увеличивающейся энергией удара, каждый раз в разные точки испытываемого отрезка проволоки и определяют величину энергии удара и соответствующую ей глубину деформирования проволоки. Энергию удара увеличивают до тех пор, пока не отрубится конец испытываемого образца проволоки. A wedge-shaped indenter is struck along the radius of the wire located on the base of the wedge-shaped with discrete increasing impact energy, each time at different points of the tested wire segment and the magnitude of the impact energy and the corresponding depth of deformation of the wire are determined. The impact energy is increased until the end of the test wire sample is chopped off.
По максимальному значению нагрузки и соответствующей деформации проволоки определяют предел прочности на растяжение, а по построенной нагрузочной кривой, связывающей силу удара и глубину внедрения инденторов, определяют предел пропорциональности, упругости, текучести и другие показатели. The maximum tensile strength is determined by the maximum value of the load and the corresponding wire deformation, and the proportionality, elasticity, yield strength, and other indicators are determined by the constructed load curve connecting the impact force and the indenter penetration depth.
Использование предлагаемого способа определения механических свойств металла проволоки снижает стоимость испытательных работ, не требует изготовления специальных образцов, прост в исполнении и позволяет получать надежные и достоверные результаты. Using the proposed method for determining the mechanical properties of metal wire reduces the cost of testing, does not require the manufacture of special samples, is simple to implement and allows you to get reliable and reliable results.
