Description

Изобретение относитс к обработке металлов давлением, а именно к штампам дл обрезки обло поковок.The invention relates to the processing of metals by pressure, in particular to dies for trimming forgings.

Цель изобретени - повышение производительности и надежности путем облегчени условий удалени поковок.The purpose of the invention is to increase productivity and reliability by facilitating the removal of forgings.

На чертеже изображен штамп в верх нем и нижнем положени х, общий вид. 9ганп состоит из верхней плиты Г JC. жестко закрепленными на ней пуансоном 2 и направл ющими втулками 3с упорнюш фланцами 4, обрезной матрицы 5 с жестко закрепленными на ней ступенчатыми направЛ кмцими колонками 6 и нижней тшиты 7.The drawing shows a stamp in its top and bottom positions, a general view. 9 ganp consists of the top plate G JC. the punch 2 rigidly fixed on it and the guide sleeves 3c are strung by flanges 4, the cut matrix 5 with stepped directions rigidly fixed on it, km 6 columns 6 and lower stitched 7.

Штамп работает следующим образом .The stamp works as follows.

Поковка с облоем укладываетс на обрезную матрицу и включаетс пресс, при этом матрица, св занна с помощью ступенчатых колонок 6 с верхней плитой 1 и ползуном пресса ( не показан, начинает перемещатьс вниз до момента ее соприкосновени с нижней плитой 7 штампа, после чего ввиду свободного хода колонок 6 в направл ющих втулках начинаетс перемещение пуансона 2 по отношению к матрице 5, который под действием усиЛИЯ пресса проталкивает поковку через пройму матрицы 5.The burr forging is placed on the trimmed matrix and the press is turned on, while the matrix, connected by means of stepped columns 6 to the upper plate 1 and the press slider (not shown, begins to move down until it contacts the lower plate 7 of the stamp, after which due to the free the movement of the columns 6 in the guide sleeves begins the movement of the punch 2 with respect to the matrix 5, which under the action of the press pushes the forging through the armhole of the matrix 5.

При обратном ходе ползуна пресса происходит подъем пуансона 2, а затем и о брезной 5 в исходноеDuring the return stroke of the press ram, the punch 2 is raised, and then about the curved 5 into the initial

положение, при этом обрезанна поковка остаетс на нижней плнте 7 щтампа, после чего может быть удалена в тару любым из известных способов , как вручную, так и с помо1цью механизма.the position, while the trimmed forging remains on the bottom plate 7 of the chip, after which it can be removed to the container using any of the known methods, both manually and with the help of a mechanism.

Claims

A DIESEL CUTTING STAMP containing a top plate with a punch rigidly fixed to it, as well as a cutting matrix placed to move in the direction of the axis of the stamp, and a bottom plate, characterized in that, in order to increase productivity and reliability by facilitating removal conditions forgings, the matrix is connected to the upper plate using stepped guide columns, as well as guide bushings rigidly fixed to the upper plate with persistent flanges for the specified columns.

1215819 ^{2 by the} power of step columns 6 with an upper plate 1 and a press slider (not shown ?, begins to move down until it contacts the lower plate 5 of the stamp 7, after which, due to the free movement of the columns 6 in the guide bushings, the movement of the punch 2 with respect to the matrix 5, which, under the influence of Julia press, pushes the forging through the armhole of matrix 5.

During the reverse stroke of the press slider, the punch 2 and then the cutting matrix 5 rise to the initial 15 position, while the cut forging remains on the bottom plate 7 of the stamp, after which it can be removed into the container by any of the known methods, either manually or with by the power of the mechanism.
