Изобретение относитс к испытательной технике и может быть использсшано дл испытани на раст жение непластичных малопрочных материалов, в частности ,- формовочных и стержневых смесей.The invention relates to a testing technique and can be used to test for stretching non-plastic low-strength materials, in particular, molding and core sands.
Известна машина дл испытани на раст жение образцов материалов, содержаща станину, механизм нагружешга с активным захватом, силоизмерителис. паосивный захват и т ги, св зывающие пассивный захват с силоизмеритвл ми, причем число т г равно количеству сил&/Измерителей 11 .A known machine for testing the stretching of material samples, comprising a stand, an active gripping load mechanism, a force measuring device. the pausive gripper and the ty guides, which connect the passive gripper with the force-measuring, and the number m t is equal to the number of forces & / Meters 11.
Недостатком этой машины вл етс сложность конструкции и испытани на ней образцов.The disadvantage of this machine is the complexity of the design and testing of samples on it.
Наиболее близкой к изобретению по технической сущности и достигаемому результату вл етс машина дл испьтт ни на раст жение образцов материалов, содержаща станину, установленные на ней механизм нагружени , силовзмер тель со сменными грузами, два mapirapHO закрепленных на станине и взаимодей-The closest to the invention to the technical essence and the achieved result is a machine for testing or stretching material samples containing a frame, a loading mechanism installed on it, a measuring force with interchangeable weights, two mapsirapHO fixed to the frame and interaction
