Description

Изобретение относитс к обработке ле таллов дазпением, и может быть применен в штампах дп вырубки деталей.The invention relates to the processing of metals by dumping, and can be applied in dp dies for cutting parts.

Известен вырубной штамПд содержащий верхнюю плиту, в которой установлены сKnown cutting strap containing the top plate, which is installed with

возможностью перемещени в вертикально направлении относительно верхней плиты подпружиненные ловители и по меньшей мере один двуплечий рычагд взаимодействующий одним концом с упором,the ability to move in a vertical direction relative to the top plate of a spring-loaded catcher and at least one two-arm lever interacting at one end with a stop,

Однако в известном, устройстве расположение упора преп тствует удалению; например механической рукой деталей из рабочей зоны штампа,However, in a known device, the location of the stop prevents removal; for example, mechanical hand parts from the working area of the stamp,

Цель изобретени - обеспечение воз- можнск;ти беспреп тх::твенного удалени механической рукой деталей из рабочей зоны.The purpose of the invention is to provide an opportunity for the unmounted removal of parts from the working area by a mechanical arm.

Поставленна цель достигаетс тем., что упор установлен на верхней неподвижной части пресса, а повитепй жестко св заны между собой планкой, взаимодействующей со свободным конусом рычага.The goal is achieved by the fact that the support is mounted on the upper stationary part of the press, and the platform is rigidly connected to each other by a strap that interacts with the free cone of the lever.

На фиг. 1 изображена верхн часть штампа в верхнем положении; на фиг. 2 то же, в нижнем, положении; на фиг. 3 вид по стрелке А на фиг. 2j на фиг. 4 вид по стрелке Б на фиг. 1.FIG. 1 shows the upper part of the stamp in the upper position; in fig. 2 the same in the lower position; in fig. 3 is a view along arrow A in FIG. 2j in FIG. 4 is a view along arrow B in FIG. one.

Штамп вырубного пресса содержит верхнюю часть Ij пуансон-матрицу 2, промежуточную плиту 3, подкладки 4, верхнюю плиту 5. В пуансоне-матрице 2 и в промежуточной плите 3 расположены ловители 6 с прзжинами 7.The die-cutter stamp contains the upper part Ij of the punch-matrix 2, the intermediate plate 3, the lining 4, the upper plate 5. In the punch-matrix 2 and in the intermediate plate 3 there are catchers 6 with pryzhinami 7.

Внутри подкладки 4 наход тс планка 8 и рычаг 9 с осью Ю. Через отверстие верхней плиты 5 проходит выталкиватель 11.Inside the lining 4 are the strap 8 and the lever 9 with the axis Y. Through the opening of the upper plate 5 passes the ejector 11.

Планка 12 с упором 13 прикреплена неподвилшо к станине пресса. Пружина 14 обеспечивает прижим рычага 9 к планке 8.Plank 12 with an emphasis of 13 attached nepodvilsho to the frame of the press. The spring 14 provides a clamp lever 9 to the strap 8.

В крайнем верхнем положении верхней части 1 щтамла ловители 6 наход тс заподлицо с нижней поверхностью 15. В съемнике 16 щтамла имеютс отверсти 17, в которые вход т ловители 6. Планка 8 выполнена в виде крестовины.In the extreme upper position of the upper part 1, the catchers 6 are flush with the bottom surface 15. In the stripper 16, there are holes 17 in which the catchers enter 6. The plank 8 is made in the form of a cross.

Claims

In the lower extreme position of the upper part 1 of the stamp between catchers 6, there is a workpiece 18. In the upper extreme position of the upper part of the stamp in the flow 19 of the mechanical arm with an ejector, 11 the part 20 is pushed out. The stamp works as follows. When the upper part of the stamp 1 moves down, the protruding end of the lever 9 rests on the stop 13 (this occurs at such a distance from the puller 16 that the tray 19 of the mechanical arm has time to leave the stamp area). The lever 9 rotates around the axis 10 and with the other end presses the bar 8. The plate 8 presses the catchers 6, which, pressing the spring 7, go outside to the distance required for fixing the workpiece. Upon further downward movement of the upper part of the stamp, the blank 18 is fixed on the puller 16. At this moment, the catchers pass into the holes 17 of the puller 16. Then a cutting is performed. The part is positioned between the cutting portions of the die and the die and the sub-die together with the upper part 1 of the die. The protruding end of the lever 9 descends from the stop 13. The springs 7 raise the catchers. Those, in turn, click on the cross, which, turning the lever 9 around the axis 10, returns it to its original position. Thus, the lower ends of the fcJ trap arms are flush with the bottom surface 15, which allows the tray 19 of the mechanical arm to freely enter the stamp area and at the top dead center position directly at the bottom surface 15, to then pull out the 2 O part which is pushed out by the pusher 11 in tray 19, Claim Formula, on the top plate of which is mounted with the ability to move relative to it in the vertical direction, spring loaded catchers and at least one two-arm lever, interacting With one end, with an emphasis, characterized in that, in order to allow unimpeded removal, for example by a mechanical hand, of parts from the working area of the press, the emphasis is mounted on the upper stationary part of the press, and the catchers are rigidly connected to each other the end of the lever.
