Description
Известен способ изготовлени тонкостенных деталей переменного сечени путем выт жки листовых заготовок. Недостатком известного способа вл етс то, что выт жка глубоких деталей требует значительного числа переходов и использовани сложных штампов.A known method of manufacturing thin-walled parts of variable cross section by drawing sheet blanks. The disadvantage of this method is that the drawing of deep parts requires a significant number of transitions and the use of complex dies.
С целью устранени указанных недостатков, предлагаетс способ изготовлени цустотелых деталей переменного сечени из трубной заготовки , заключающийс в том, что образование нужной формы детали осуществл етс прессованием по неподвил ной оправке-стержню, изготовленному по форме внутренней полости детали, в матрице, внутренн поверхность которой выполнена по наружной поверхности детали.In order to eliminate these drawbacks, a method is proposed for fabricating single-piece parts of variable cross-section from a tubular billet, which consists in forming the desired shape of a part by pressing on a baseless mandrel-rod made according to the shape of the internal cavity of the part in a matrix, the inner surface of which is made on the outer surface of the part.
На чертеже показана конструкци штампа, где / - ползун пресса, 2 - пуансон, 5 - оправка, 4 - заготовка, 5 - матрица, 6 - выталкиватель , 7 - стол пресса.The drawing shows the design of the stamp, where / is the press slider, 2 is the punch, 5 is the mandrel, 4 is the workpiece, 5 is the die, 6 is the ejector, 7 is the press table.
Принцип действи описанного штампа состоит в том, что при ходе ползуна вниз оправка становитс в крайнее полох ение, ограниченное выталкивателем. При дальнейшем ходе ползуна пуансон давит на заготовку , заставл последнюю течь в зазор между матрицей и оправкой и образовывать деталь заданной формы.The principle of the described stamp is that when the slide is moved down the mandrel becomes extremely polished, limited by the ejector. During the further course of the ram, the punch presses on the workpiece, forcing the latter to flow into the gap between the die and the mandrel and form a part of a given shape.
При обратном ходе ползуна происходит выталкивание изготовленной детали.When the slide is reversed, the manufactured part is pushed out.
Предмет изобретени Subject invention
Способ изготовлени пустотелых деталей переменного сечени , отличающийс тем, что, с целью уменьшени сложности их изготовлени , примен етс прессование трубной заготовки, использующее принцип истечени металла из нее.A method of manufacturing hollow parts of variable cross section, characterized in that, in order to reduce the complexity of their manufacture, the extrusion of a tubular billet is used, using the principle of metal outflow from it.
