(5) СПОСОБ ОПРЕДЕЛЕНИЯ НАПРЯЖЕНИЙ СЖАТИЯ(5) METHOD FOR DETERMINING COMPRESSION STRESSES
ВО ФЛАНЦЕ ЛИСТОВОЙ ЗАГОТОВКИ ПРИ ВЫТЯЖКЕIN THE FLANGE OF THE SHEET PREPARATION IN THE EXTRACT
II
Изобретение относитс к испытани м материалов и может быть использовано при определении напр жений сжати во фланце листовой заготовки при выт жке дл отработки технологических режимов выт жки.The invention relates to the testing of materials and can be used in the determination of compressive stresses in the flange of a sheet blank during stretching to test the technological conditions of stretching.
Известен способ определени напр жений сжати во фланце листовой заготовки при выт жке, заключающийс в том, что во фланце заготовки выполн ют радиальные вырезы, устанавливают в них вставки в виде скобы с тензодатчиками, причем размеры рабочих частей скоб совпадают с размерами соответствующего выреза, выт гивают заготовку и измер ют напр жени сжати . 1 A known method for determining compressive stresses in the flange of the sheet blank during stretching consists in the fact that radial cuts are made in the flange of the billet, inserts are installed in the form of a clip with strain gauges, and the sizes of the working parts of the clips coincide with the dimensions of the corresponding cut, are pulled the workpiece and compressive stresses are measured. one
Недостатком способа вл етс его сложность, так как дл определени напр жений сжати во фланце необходимо выполнить несколько, вырезов, в каждый из них установить свою вставку и проводить измерени на каждой вставке.The disadvantage of this method is its complexity, since in order to determine the compressive stresses in the flange, it is necessary to make several cutouts, in each of them install your insert and take measurements on each insert.
Цель изобретени - упрощение испытани .The purpose of the invention is to simplify the test.
Поставленна цель достигаетс тем, что согласно способу определени напр жений сжати во фланце листовой заготовки При выт жке, заключающемус в том, что во фланце заготовки выполн ют радиальный вырез, устанавливают в него вставку, размеры рабочей части которой совпадают с размерами выреза, выт гивают заготовку и измер ют напр жение сжати , вырез выполн ют посто нной ШИР11НЫ не более трех толщин заготовки , используют вставку с углублени ми на ее боковых поверхност х, предназначенными дл взаимодействи с поверхност ми выоеза, а о напр жени х сжати суд т по количеству материала листовой заготовки, оставшегос в углублени х вставки.The goal is achieved by the fact that according to the method of determining compressive stresses in the flange of the sheet blank. When drawing, consisting in the fact that a radial cut is made in the flange of the workpiece, an insert is installed into it, the dimensions of the working part of which coincide with the cut dimensions. and the compressive stress is measured, the notch is made of a constant WIDTH not more than three thicknesses of the preform, use an insert with recesses on its side surfaces designed to interact with the extraction surfaces, and compressors are judged by the amount of sheet material remaining in the recesses of the insert.
