Description

Дл  испытани  листового материала на срез в технике весьма часто примен ютс  машины штамповочного типа, в которых образец зажимаетс  своими концами в тиски, снабженные вертикальной направл юш,ей дл  штампа или пунсона, деформирующего образец путем срезывани .For testing sheet material in the technique, stamping-type machines are quite often used in which a specimen is clamped with its ends in a vice, provided with a vertical direction, for a stamp or punch that deforms the specimen by shearing.

Предлагаемое изобретение имеет назначением использовать прибор указанного типа дл  испытани  на срез малов зких материалов, напр., дерна, что достигаетс  применением тисков, обеспечивающих целость зажатых в них концов образца от расползани  в моменты давлени , которое производит пунсон или штамп на образец.The present invention is intended to use the device of the specified type to test for the cutting of low-viscous materials, for example turf, which is achieved by using a vice to ensure that the ends of the specimen clamped in them from spreading out during the moments of pressure that produces a punch or stamp on the specimen.

На чертеже фиг. 1 и 3 изображают виды прибора с двух сторон и фиг. 2- вид его сверху.In FIG. 1 and 3 show views of the device from two sides, and FIG. 2 - view from above.

На дерев нном основанни 7 расположены дерев нный, неподвижно укрепленный на указанном основании пр моугольный сруб 2 и второй такого же размера и вида сруб 2. Последний может быть перемещаем в направл ющих 8, одним концом закрепленных на срубе 2, а на другом снабженных прорезами 9 дл  направлени  движени  шурупа JO, св занного со срубом 2; дл  непосредственной т ги сруба 2 )On the wooden base 7 there are wooden, fixed forwards on a specified base, rectangular log house 2 and a second one of the same size and type of log house 2. The latter can be moved in the guides 8, fixed at the other end on the log house 2, and at the other end 9 for guiding the movement of the screw JO associated with the frame 2; for immediate log cabins 2)

жит скрепленна  с ним планка /5, винт которой 4 перемещаетс  в пазу /2 основани  / прибора. Верхн   плоскость срубов служит одной из губок 3 дл  зажима образца и снабжена по своим углам вертикально сто щими винтами 7/ дл  направлени  движени  вверх и вниз верхних губок 5 тех же зажимов. Указанные губки зажимов снабжены иглами, расположенными друг против друга в шахматном пор дке. В углах срубов, обращенных друг к другу , закреплены железные угольники 16, служащими направл ющими дл  пунсона или штампа.The bracket / 5 is fastened to it, the screw of which 4 is moved to the groove / 2 of the base / device. The upper plane of the log houses serves as one of the jaws 3 for clamping the specimen and is provided at its corners with vertical screws 7 / for guiding the upward and downward movement of the upper jaws 5 of the same clamps. The said jaws of the clamps are provided with needles arranged against each other in a checkerboard pattern. At the corners of the log houses, facing each other, iron gons 16 are fixed, which serve as guides for a punch or punch.

При испытании образца на срез, последний закладываетс  концами в размещенные на заранее указанном рассто нии друг от друга зажимы и закрепл етс  в них гайками 75 винтов //; дл  равномерной передачи давлени  образцу примен етс  прокладка 77 лсесткого материала, помещаема  под штамп или пунсон.When a sample is tested for shear, the latter is laid with the ends into the clamps placed at a predetermined distance from each other and fastened in them with nuts and screws 75; For uniform pressure transfer to the specimen, a gasket of 77 of the best material is used, placed under the stamp or punches.

Давление на образец через прокладку 77 передаетс  прессом, причем прочность или сила сопротивлени  образца на срез определ етс  индикаторами давлени , характеризующими работу пресса.The pressure on the sample through the gasket 77 is transmitted by the press, and the strength or resistance of the sample to the shear is determined by pressure indicators characterizing the operation of the press.

Предмет изобрет ен-и .The subject of the invention en-and.

Винтовые тиски к прибору дл  испытани  листового материала на срез, отличающиес  тем, что дл  креплени Screw vice to the device for testing sheet material for shearing, characterized in that for fastening

в них малов зкого материала обе губки 3 и 5 тисков снабжены иглами 6, расположенными друг против друга в шахматном пор дке.in them of a low viscous material, both sponges 3 and 5 of a vice are equipped with needles 6 arranged opposite each other in a checkerboard pattern.
