Description
(5) УСТРОЙСТВО дл ИСПЫТАНИЯ ПЛАСТИНЧАТЫХ ОБРАЗЦОВ НА УСТАЛОСТЬ ПРИ ЧИСТОМ ИЗГИБЕ(5) DEVICE FOR TESTING PLATE SAMPLES FOR FATIGUE DURING CLEAN BENDING
Изобретение относитс к исследованию прочностных свойств материалов, а именно к устройствам дл испытани пластинчатых образцов, и может найти применение при испытании сварных соединений на усталость при чистом изгибе .The invention relates to the study of the strength properties of materials, namely, devices for testing plate samples, and can be used in fatigue testing of welded joints during clean bending.
Известно устройство дл испытани на усталость металлических полос, содержащее два наход щихс в зацеплении зубчатых колеса с захватами дл креплени концов полос, выполненными в виде двух пар роликов, установленных с возможностью вращени на ос х, кривошипно-шатунный механизм поворота колес и упоры, ограничивающие перемещение концов полос в захватах 1-.A device for testing the fatigue of metal strips is known, comprising two engaged gears with grippers for fastening the ends of the strips, made in the form of two pairs of rollers mounted for rotation on axles, a crank-and-conrod mechanism for turning wheels and stops that restrict movement the ends of the bands in the grippers 1-.
Недостатком устройства вл етс низка точность испытани , так как в процессе изгиба полосы посто нно мен етс длина испытуемого участка.The disadvantage of the device is the low accuracy of the test, since the length of the test section varies constantly during the bending of the strip.
Наиболее близким по технической сущности к изобретению вл етс устройство дл испытани пластинчатых образцов на усталость при чистом изгибе , содержащее два поворотных зубчатых сектора с установленными на них захватами дл креплени концовThe closest in technical essence to the invention is a device for testing plate-like fatigue specimens with a clean bend, containing two rotatable toothed sectors with grippers attached to them for fastening the ends
образцов и механизм поворота секторов , включающий двухстороннюю зубчатую рейку и ее привод, в этом устройстве захваты жестко соединены с samples and a sector rotation mechanism, including a double-sided rack and its drive, in this device the grippers are rigidly connected to
JP зубчатыми секторами .JP jagged sectors.
Недостатком известного устройства вл етс невозможность испытани образцов различной длины вследствие неизменного рассто ни между захватами .A disadvantage of the known device is the impossibility of testing samples of different lengths due to the constant distance between the grippers.
Цель изобретени - расширение функциональных возможностей за счет , испытани образцов разной длины.The purpose of the invention is to expand the functionality by testing samples of different lengths.
