Description
Предлагаемый способ выт гивани изделий из листового металла характеризуетс многократным выворачиванием заготовки и отличаетс от известного способа обратной выт жки (с однократным реверсированием ) схемой течени металла.The proposed method of stretching articles from sheet metal is characterized by repeated turning of the workpiece and differs from the known method of reverse drawing (with a single reversal) by the metal flow pattern.
Процесс выт жки по предлагаемому способу осуществл етс следующим образом: перва операци выт жки ироизводитс обычным способом .на прессе двойного действи (ф|иг. 1) в матрице / пуансолом 2. Устанавливаема заготовка фиксируетс прижимсш 5. После выт жки заготовка 3 выталкиваетс из матрицы / выталкивателем 4.The drawing process according to the proposed method is carried out as follows: the first drawing operation is carried out in the usual way. In a double-acting press (form 1) in the die / punch 2. The workpiece is clamped fixed 5. After drawing, workpiece 3 is pushed out of the die ejector 4.
При второй операции цилиндрзаготовку 5 (фиг. 2) переворачивают вверх днищем и надевают на цилиндрическую полую матрицу 6 второго пресса, высота которой несколько больше высоты заготовки 3. Наружный диаметр матрицы 6 равен внЗтреннему диаметру заготовки 3, а внутренний наружному диаметру цилиндра-выт жки 7.In the second operation, the cylinder billet 5 (Fig. 2) is turned upside down and put on a cylindrical hollow matrix 6 of the second press, the height of which is somewhat greater than the height of the workpiece 3. The outer diameter of the matrix 6 is equal to the inside diameter of the workpiece 3, and the inner diameter of the cylinder-extract 7 .
После такой установки заготовки на прессе осуществл етс операци выт жки, сопровождающа с выворачиванием .After such installation of the workpiece on the press, a stretching operation is carried out, accompanied with turning.
Последующие операции выт жки-выв0;рачиван и цроиавод тс в том же пор дке, -а количество операций определ етс расчето м.Subsequent stretching operations were carried out in the same order, and the number of operations is determined by the calculation of m.
Предмет изобретени Subject invention
Способ выт гивани полых изделий из листового металла, отличающийс тем, что изделие выворачивают наизнанку несколько раз путем выт гивани каждый раз в направлении, обратном предыдущей выт жке.A method of drawing hollow articles from sheet metal, characterized in that the product is turned inside out several times by stretching each time in the direction opposite to the previous drawing.
