Цель изобретения - повышение произ- , водительности пресса и расширение номенклатуры изготавливаемых деталей.The purpose of the invention is to increase the productivity of the press and expand the range of manufactured parts.

Это достигается тем, что предлагаемый штамп снабжен смонтированными в верхней плите нажимными элементами и размещенными в нижней плите стержнями, · взаимодействующими при рабочем ходе штампа одними торцами с нажимными элементами, а другими - с траверсой, при этом толкатель и штифты установлены с образованием зазора между ними в закрытом положении штампа. Нажимные элементы выполнены-в виде направляющих колонок, связывающих верхнюю и нижнюю плиты.This is achieved by the fact that the proposed stamp is equipped with pressure elements mounted in the upper plate and rods placed in the lower plate, · interacting during the working stroke of the stamp with one end face with the pressing elements and the other with a traverse, while the pusher and pins are installed to form a gap between them in the closed position of the stamp. The pressure elements are made in the form of guide columns connecting the upper and lower plates.

На фиг. 1 изображен предлагаемый штамп, используемый в многопозиционном прессе для пробивки отверстий в деталях, в закрытом положении; на фиг. 2 - то же устройство в разомкнутом положении.In FIG. 1 shows the proposed stamp used in a multi-position press for punching holes in parts in the closed position; in FIG. 2 - the same device in the open position.

Штамп содержит буфер 1 с траверсой 2, с которой контактируют штифты 3, установленные в нижней плите 4 так же, как и толкатель 5, причем между толкателем 5 и штифтами 3 имеется зазор 6. С траверсой 2 взаимодействуют стержни 7, помещенные в нижней плите 4 и имеющие контакт с нажимными элементами 8, выполненными в виде направляющих колонок, укрепленных на верхней подвижной плите 9. На плите 9 закреплено прижимное устройство 10, прижимающее деталь 11 при обработке пуансонами 12, полу- чающими радиальное перемещение от наклонной поверхности 13 подпружиненного кольца 14 при воздействии на него штифтов 15, закрепленных на подвижной плите 9.The stamp contains a buffer 1 with a traverse 2, with which the pins 3, mounted in the lower plate 4 in the same way as the pusher 5, come into contact, and there is a gap 6 between the pusher 5 and the pins 3. The rods 7 interact with the traverse 2 located in the lower plate 4 and having contact with the pressure elements 8, made in the form of guide columns, mounted on the upper movable plate 9. On the plate 9 is fixed a clamping device 10, which holds the part 11 when machining with punches 12, which receive radial movement from the inclined surface 13 of the spring loaded o rings 14 when exposed to pins 15 mounted on a movable plate 9.

Деталь 11 (см. фиг. 2) поднята до уровня зеркала 16 штампа толкателем 5, выдвинутым до этого уровня траверсой 2, находящейся в верхнем положении, через штифты 3. Зеркало штампа составляет и верхняя поверхность 17. кольца 14, а пуансоны 12 находятся в исходном положении. Стержни 7 при верхнем положении траверсы 2 буфера 1 не выходят за пределы зеркала 16 штампа, на котором рас-15 положена деталь 11, захваченная грейфером 18, находящимся. также на зеркале 16 штампа.Part 11 (see Fig. 2) is raised to the level of the mirror 16 of the stamp by the pusher 5, extended to the same level by the traverse 2, which is in the upper position, through the pins 3. The mirror of the stamp also makes up the upper surface 17. of the ring 14, and the punches 12 are in starting position. The rods 7 with the upper position of the traverse 2 of the buffer 1 do not extend beyond the limits of the mirror 16 of the stamp, on which the raz-15 rests the part 11, captured by the grab 18 located. also on the mirror 16 stamp.

Штамп работает следующим образом.The stamp works as follows.

При рабочем ходе пресса плита 9 на- 20 чинает приближаться к плите 4 и прижимное устройство 10 входит в контакт с деталью 11, передвинутой по зеркалу 16 грейфером 18 на плиту 4. В это же время нажимные элементы 8 входят в плиту 25 и надавливают через стержни 7 на траверсу 2. Пружина буфера 1 начинает сжиматься, траверса 2 опускается, а вместе с ней опускаются штифты 3 и толкатель с прижатой к нему прижимным устрой- 30 ством 10 деталью 11. После того, как деталь опустится на плиту 4, при дальнейшем движении вниз плиты 9 штифты 15 надавливают на подпружиненное кольцоDuring the working stroke of the press, the plate 9 starts to approach the plate 4 and the pressing device 10 comes into contact with the part 11, moved along the mirror 16 by the grab 18 to the plate 4. At the same time, the pressure elements 8 enter the plate 25 and press through the rods 7 on the crosshead 2. The spring of the buffer 1 begins to compress, the crosshead 2 lowers, and with it the pins 3 and the pusher with the clamping device 30 pressed against it by the part 11. After the part has lowered onto the plate 4, with further movement down plate 9 pins 15 push on a spring loaded ring about

14, которое при опускании воздействует 35 своими наклонными поверхностями на пуансоны 12, которые получают радиальное перемещение и при рабочем ходе обрабатывают деталь в зависимости от вида операции (в данном случае пробивают отвер- ⁴⁰стие). Причем некоторая часть пуансона 12 оказывается внутри детали. При рабочем ходе пуансонов 12 происходит дальнейшее сжатие пружины буфера 1 под действием нажима на него через стержни ⁴⁵7 нажимных элементов 8. Траверса 2 опускается, а вместе с ней штифты 3, так что в закрытом положении штампа имеется зазор 6 между толкателем 5 и его штифтами 3. ⁵⁰ 14, which acts by lowering their inclined surfaces 35 on the punches 12, which receive radial movement and during working the workpiece depending on the type of operation (in this case ⁴⁰ punched otver- stie). Moreover, some part of the punch 12 is inside the part. During the working stroke of the punches 12, the spring of the buffer 1 is further compressed by pressing it through the rods ⁴⁵ 7 of the pressure elements 8. The beam 2 is lowered, and the pins 3 are with it, so that in the closed position of the stamp there is a gap 6 between the pusher 5 and its pins 3. ⁵⁰

При обратном ходе зазор 6 обеспечивает запаздывание выталкивания детали толкателем 5 w тех пор, пока пуансоны 12 не вернутся в исходное положение,With the reverse stroke, the gap 6 provides a delay in the ejection of the part with the pusher 5 w until the punches 12 return to their original position,

т.е. не выйдут из детали и не освободят путь для детали из рабочей позиции нижней плиты. Это происходит следующим образом. При движении плиты 9 вверх вмес— 5 те с ней движутся подпружиненное кольцо 14, одновременно передвигающее своими наклонными поверхностями 13 пуансоны 12 в исходное положение. После отхода пуансонов 12 в исходное положение и подъема штифтов 3 до толкателя 5 толка,тель начинает двигаться вверх и выталкивает деталь 11 до зеркала 16 штампа, причем прижимное устройство 10 постоянно до полного подъема детали 11 прижимает ее к толкателю 5. При дальнейшем движении плиты 9 вверх происходит отрыв прижимного устройства 10 от детали 11, выход нажимных элементов 8 из нижней плиты 4 и подъем их из зоны действия грейфера 18, который захватывает деталь 11 и перемещает ее на следующую позицию.those. will not leave the part and will not clear the way for the part from the working position of the bottom plate. This happens as follows. When the plate 9 moves upward instead of 5, they move with it a spring-loaded ring 14, which at the same time moves the punches 12 to their original position with their inclined surfaces 13. After the punches 12 return to their original position and the pins 3 are lifted to the push pusher 5, the body starts moving up and pushes the part 11 up to the punch mirror 16, and the pressing device 10 constantly presses it against the pusher 5 until the part 11 is fully lifted. With further movement of the plate 9 upward, the clamping device 10 is detached from the part 11, the pressure elements 8 exit from the lower plate 4 and lift them out of the range of the grab 18, which grabs the part 11 and moves it to the next position.

Claims

The invention relates to pre-fabrication equipment and can be used to make products that require multi-stage processing in a press such as a separator, bearing rings, and the like. A stamp for multi-position presses is known that contains a fixed lower and a movable upper plate, a working tool and a mechanism for ejecting parts, including a buffer with a cross bar, which interacts during the return stroke of the upper plate by means of pins with a pusher tl). The purpose of the invention is to increase the productivity of the press and expand the range of manufactured parts. This is achieved by the fact that the proposed stamp is equipped with pressure elements mounted in the upper plate and rods in the lower plate that interact with the working stroke of the stamp with one ends with pressure elements and with other elements with a cross bar, while the pusher and pins are installed to form a gap between them in the closed position of the stamp. The pressure elements are made in the form of guide columns connecting the upper and lower plates. FIG. 1 shows the proposed die used in a multi-position punching press in the parts in the closed position; in fig. 2 - the same device in the open position. The stamp contains buffer 1 with a crosspiece 2, in which the pins 3 in contact with the bottom plate 4 are in the same way as the pusher 5, and there is a gap 6 between the pusher 5 and the pins 3 6. The bars 7 interact with the cross bar 2 placed in the bottom plate 4 and having contact with pressure elements 8, made in the form of directional columns, mounted on the upper padding plate 9. On the plate 9, the clamping device 1O is fixed, the clamping part 11 is processed by punches 12, receiving radial movement from the inclined surface 13 twist When the pins 15 fixed on the movable plate 9 are exposed to it, the part 11 (see FIG. 2) is raised to the level of the mirror 16 of the stamp by the pusher 5 extended to this level by the cross member 2 being in the upper position through pins 3. The stamp mirror constitutes the upper surface 17. the rings 14, and the punches 12 are in the initial position. The rods 7 at the upper position of the crosspiece 2 of the buffer 1 do not extend beyond the limits of the mirror 16 of the stamp on which the part 11 is seized, captured by the grapple 18, which is also on the mirror 16 of the shtampa. The stamp works as follows. During the working stroke of the press, the plate 9 begins to approach the plate 4 and the pressing device 10 comes into contact with the part 11, moved over the mirror 16 by the grapple 18 onto the plate 4. At the same time, the pressure elements 8 enter the plate 4 and are pressed through the rods 7 on traverse 2. Buffer spring 1 starts compressing, traverse 2 lowers, and with it lowers pins 3 and pusher 5c with part 11 pressed against it by clamping device 10. After the part lowers onto plate 4, it moves further down plate 9 pins 15 press on the spring-loaded ring 14 which, when lowered, acts with its inclined surfaces on the punches 12, which receive a radial displacement and, during a working stroke, process the part depending on the type of operation (in this case punch a hole). Moreover, some of the punch 12 is inside the part. During the working stroke of the punches 12, the spring of the buffer 1 is further compressed by pressing it through the rods 7 of the pressing elements 8, the Traverse 2 is lowered, and along with it the pins 3, so that in the closed position of the probe there is a gap 6 between the pushers 5 and its pieces 3 In the course of the return stroke, the gap 6 provides a delay in pushing the part by the pusher 5 41 O until the punches 12 return to their original position, 0. will not exit the part and will not release the part for the part from the working position of the bottom plate. This happens as follows. When the plate 9 moves upwards, the spring-loaded ring 14 moves along with it, simultaneously moving its inclined surfaces 13 punches 12 to the initial position. After the punches 12 retire to their original position and lift, the pins 3 to the pusher 5, the pusher begins to move upwards and pushes the part 11 to the stamp mirror 16, and the pressing device 1O constantly presses it to the pusher 5. As the plate 9 continues upwards, the clamping device 1O is separated from the part 11, the pressure elements 8 exit from the bottom plate 4 and are lifted out of the zone of action of the grapple 18, which captures the part 11 and moves it to the next position.
