Description
Выт жка пустотелых цилиндрических изделий из листовых материалов известна и широко распространена . Дл выт жек пустотелых цилиндрических изделий из листа вырезаютс потребного диаметра кружки, которые подвергаютс выт жке . При вырезке из листа кружков получаетс значительное количество отходов.Extracting hollow cylindrical articles from sheet materials is known and widely distributed. For drawing hollow cylindrical articles from a sheet, circles of the required diameter are cut, which are subjected to drawing. Cutting from a sheet of circles results in a significant amount of waste.
Предлагаемый способ производства пустотелых цилиндрических изделий осуществл етс с весьма незначительными потер ми металла в отходы, путем применени нескольких дополнительных промежуточных операций выт жки фасонными пуансонами и матрицами.The proposed method for the production of hollow cylindrical products is carried out with very insignificant metal losses to waste, by applying several additional intermediate stretching operations with shaped punches and dies.
Сущность предлагаемого способа заключаетс в следующем.The essence of the proposed method is as follows.
Листовой материал раскраиваетс на квадраты или шестигранки (без отходов), как изображено на фиг. 1. Квадрат или шестигранник подвергаетс первой выт жке пуансоном также квадратной или шестигранной формы с закругленными углами, как указано на фиг. 2.The sheet material is cut into squares or hexagons (without waste), as shown in FIG. 1. A square or hexagon is subjected to a first drawing by a punch also of square or hexagonal shape with rounded corners, as indicated in FIG. 2
При выт жке таким пуансоном участки заготовки, заштрихованные параллельными лини ми, загибаютс , а участки, заштрихованные сеткой , выт гиваютс . После этой операции заготовка приобретет форму, сечение которой соответствует внешнему контуру фиг. 3. Эта заготовка, подверга сь выт жке круглым пуансоном , превратитс в цилиндр с неровными кра ми, которые затем обрезаютс .When such a punch is pulled, the parts of the workpiece shaded with parallel lines are bent, and the areas shaded with a grid are pulled out. After this operation, the workpiece will acquire a shape, the cross section of which corresponds to the external contour of FIG. 3. This preform, having been drawn by a round punch, is transformed into a cylinder with uneven edges, which are then cut.
Предмет изобретени Subject invention
Способ производства пустотелых цилиндрических изделий путем многооперационной выт жки из листовых материалов, отличающийс тем, что, с целью снижени отходов листовых металлов и исключени необходимости в штамповой оснастке дл изготовлени заготовок , исходную форму заготовки принимают квадратной или шестигранной , а дл первой выт жки примен ют фигурный пуансон,- контур которого соответствует контуру заготовки .The method of producing hollow cylindrical articles by multi-operative drawing from sheet materials, characterized in that, in order to reduce the waste of sheet metals and eliminate the need for die tooling for the manufacture of blanks, the original shape of the blank is square or hexagonal, and for the first drawing punch - the contour of which corresponds to the contour of the workpiece.
