Изобретение, относитс к испытательной технике , а именно к испытани м материалов на раст жение.The invention relates to a testing technique, namely to tensile testing of materials.
Известно устройство к испытательной машине дл плоских крестообразных образцов при двухосном нагружении, содержащее рычажный механизм с регулируемой длиной рычагов и две пары захватов дл креплени испытуемого образца.A device for a testing machine for flat cross-shaped specimens under biaxial loading is known, comprising a lever mechanism with adjustable lever length and two pairs of grippers for fastening the test specimen.
Недостатком известного устройства вл етс невозможность осуществлени двухосного нагружени по схеме раст жени по одной оси и сжатие - по другой.A disadvantage of the known device is the impossibility of carrying out biaxial loading according to a tension scheme along one axis and compression along another.
Предлагаемое устройство к испытательной мащине, отличаетс от известного тем, что, с с целью получени различных видов нагружени по ос м, оно снабжено т гами дл креплени пары захватов к захватам испытательной машины, рычажным механизмом, выполненным в виде двух пар рычагов, одни концы которых св заны с т гами, и парой поперечин, размещенных параллельно т гам. Концы каждой поперечины св заны с концами пары рычагов , а средние части - с захватами дл креплени образца. Кроме того, т ги установлены с возможностью регулировани рассто ни между ними, а длина поперечин выбираетс большей минимального рассто ни между т гами.The proposed device to the test facility differs from the known one in that, in order to obtain various types of loading along the axles, it is equipped with tacks for attaching a pair of grippers to the grips of the testing machine, a lever mechanism made in the form of two pairs of levers, one ends are connected to the rods, and a pair of crossbars, arranged parallel to t ham. The ends of each crosspiece are connected to the ends of a pair of levers, and the middle parts are provided with grips for fastening the sample. In addition, the rods are installed with the possibility of adjusting the distance between them, and the length of the crossbars is chosen to be greater than the minimum distance between the rods.
На чертеже изображена схема предлагаемого устройства. Устройство содержит рычажный механизм, выполненный в виде двух пар рычагов I, 2 и 3, 4 и пару поперечин 5 и 6, двеThe drawing shows a diagram of the proposed device. The device contains a lever mechanism, made in the form of two pairs of levers I, 2 and 3, 4 and a pair of crossbars 5 and 6, two
пары захватов 7, 8 и 9, 10 дл креплени образца И. Т ги 12 и 13, служащие дл креплени захватов 7 и 8 к захватам испытательной машины (на чертеже не показана), шарнирно соединены с рычагами 1-4. Рычаги 1-4 имеют резьбовые концы, к которым присоединены с помощью резьбовых втулок 14-17 поперечины 5 и 6. Поперечины 5 и 6 имеют в средних част х резьбовые отверсти , служащие дл креплени в них захватов 9 и 10.pairs of grippers 7, 8 and 9, 10 for fastening the specimen I. Tg 12 and 13, serving for fastening grippers 7 and 8 to the grips of the testing machine (not shown), are hinged to the arms 1-4. The levers 1-4 have threaded ends to which crossbars 5 and 6 are attached by means of threaded bushings 14-17. Crossbars 5 and 6 have threaded holes in the middle parts, which serve to fasten grippers 9 and 10 in them.
Резьбовые соединени всех деталей служат дл изменени рассто ний между ними и величин плеч рычагов.The threaded connections of all the parts serve to change the distance between them and the values of the arms of the levers.
Устройство работает следующим образом.The device works as follows.
В зависимости от поставленной задачи образец может быть испытан или на раст жение по обоим ос м, или на раст жение то одной оси и сжатие по другой. При испытании образца на раст жение по обеим ос м рассто ние между т гами 12 и 13 устанавливаетс меньшим, чем длина поперечин 5 и 6. В этом случае при приложении раст гивающих нагрузок к т гам 12 и 13, образец через захваты 7 и 8 раст гиваетс по вертикальной оси. Рьпаги 1-4 поворачиваютс таким образом, чтоDepending on the task, the sample can be tested either for stretching along both axes, or stretching one axle and compressing along the other. When a sample is tested for stretching along both axes, the distance between the thrusters 12 and 13 is set smaller than the length of the crossbars 5 and 6. In this case, when tensile loads are applied to tons 12 and 13, the sample through the grippers 7 and 8 is shown on the vertical axis. Snapshots 1-4 rotate in such a way that
рассто ние между перекладинами 5 и б увеличиваетс , а образец, через захваты 9 и 10 раст гиваетс по горизонтальной оси.the distance between the rungs 5 and b increases, and the sample, through the grippers 9 and 10, stretches along the horizontal axis.
При испытании образца на раст жение по одной оси и сжатие по другой, рассто ние между т гами 12 и 13 устанавливаетс большим длины поперечин 5 и 6. В этом случае, при приложении раст гивающих усилий к т гам 12 и 13, образец 11 раст гиваетс по вертикальной оси захватами 7 и 8.When a specimen is tested for stretching along one axis and compressing along another, the distance between the thrusts 12 and 13 is set longer than the crossbars 5 and 6. In this case, when tensile forces are applied to tam 12 and 13, sample 11 stretches on the vertical axis of the grippers 7 and 8.
Рычаги 1-4 поворачиваютс таким образом , что рассто ние между понеречинами 5 и 6 уменьшаетс и образец П сжимаетс захватами 9 и 10 по горизонтальной оси.The levers 1-4 rotate in such a way that the distance between the ribs 5 and 6 is reduced and the specimen P is compressed by the grips 9 and 10 along the horizontal axis.
Мен с помощью втулок 14-17 длину рычагов 1-4 можно регулировать как соотношение усилий по вертикально и горизонтальной оси, так и соотношение скоростей деформировани по этим ос м нри заданной скорости деформировани по вертикальной оси.With the help of sleeves 14-17, the length of levers 1–4 can be controlled both by the ratio of the forces along the vertical and horizontal axes, and the ratio of the deformation rates along these axes to a given deformation rate along the vertical axis.
