Description

Ппевмоцилиндрами 13 опорные пластины 12 перемещаютс к центру н включают в работу задавки 11, которые от нажати пресса на секции 16 и 17 матрицы окончательно соедин ют последние с нижними секци ми 3 и 4 матрицы.By first cylinders 13, the support plates 12 move to the center n to engage the work 11, which, by pressing the press on the matrix sections 16 and 17, finally connect the latter with the lower sections 3 and 4 of the matrix.

При небольшом подъеме клина задавки 11 выключаютс пневмоцилиндрами 13, после чего начинаетс одновременно процесс гибки и высадки.With a slight rise of the wedge, the bushing 11 is turned off by the pneumatic cylinders 13, after which the bending and disembarking process starts simultaneously.

По окончании штамповки колена клин 10 вместе с верхними секци ми 16 и 17 матрицы и цуансоном 18 поднимаетс , надставка 19 остаетс заштампованной в колене. После этого поковка удал етс из штампа, рабочие части штампа станов тс в исходное положение , заготовка укладываетс дл штамповки очередного колена и процесс повтор етс .At the end of the punching of the knee, the wedge 10, together with the upper sections 16 and 17 of the matrix and the cucon 18, rises, the extension 19 remains stamped into the knee. Thereafter, the forging is removed from the die, the working portions of the die are returned to their original position, the workpiece is laid for the next knee, and the process is repeated.

Фиксаци на колонки нижних секций матрицы с верхними секци ми матрицы, одновременна передача усилени пресса через клин на верхние и нижние подвижные секции матрицы под углом 22-30° исключает их раскрытие и обеспечивает зажим заготовки непосредственно от давлени клином, что позвол ет уменьшить габариты клина и упростить копструкцию штампа.Fixing the columns of the lower sections of the matrix with the upper sections of the matrix, while simultaneously transmitting the press reinforcement through the wedge to the upper and lower moving sections of the matrix at an angle of 22-30 °, eliminates their opening and ensures the workpiece is clamped directly from the wedge pressure, which reduces the size of the wedge and simplify the coping of the stamp.

Claims

Invention Formula

A punch for stamping large-sized crankshafts using the upset-bending method, which contains a bottom plate with the lower sections of the dies mounted on it with the possibility of horizontal movement

vertically movable clamp, upper sections of the dies, as well as a bending punch fixed in the upper part of the die with wedge side surfaces, characterized in that, in order to simplify the design, save metal, increase productivity, and improve the quality of the shafts by eliminating compression cheeks, the bending punch is provided with a removable extension to prevent the cheeks from squeezing,

and the upper sections of the dies are mounted in the upper part of the stamp and are made with the corresponding wedge surfaces, while the upper and lower sections of the dies are fixed against relative movement

columns.
