Description

Изобретение относитс к области автоматизации штамповочных работ и может быть использовано в устройствах дл удалени изделий из рабочей зоны пресса.The invention relates to the field of automation of stamping operations and can be used in devices for removing articles from the working area of a press.

Известно устройство дл удалени изделий из рабочей зоны пресса, содержащее удал ющий щибер, снабженный пружиной и шарнирно-закрепленный на конце рычага, шарнирно-установленным на неподвижной части пресса и кинематически св занным с подвижной частью I.A device for removing articles from the working area of a press is known, comprising a removal spike, equipped with a spring and hinged at the end of the lever, hingedly mounted on the stationary part of the press and kinematically connected with the movable part I.

Недостатком известного устройства вл етс невозможность удалени отходов из рабочей части пресса, невозможность обеспечени перемещени шибера на величину, большую хода ползуна пресса.A disadvantage of the known device is the impossibility of removing waste from the working part of the press, the impossibility of ensuring the displacement of the gate by an amount greater than the stroke of the press ram.

Цель изобретени - обеспечение возмож нести удалени отхода и перемещени шибера на величину, большую хода ползуна пресса.The purpose of the invention is to ensure that it is possible to carry out the removal of waste and movement of the gate by an amount greater than the stroke of the press ram.

Цель достигаетс тем, что на свободном конце шибера со стороны матрицы выполнен выступ, посто нно взаимодействующий с зеркалом матрицы, а рычаг св зан с приводным валом пресса через систему рычагов и кулачок , закрепленный на приводном валу.The goal is achieved by the fact that at the free end of the gate from the side of the die there is a protrusion, which constantly interacts with the mirror of the die, and the lever is connected to the drive shaft of the press through a system of levers and a cam mounted on the drive shaft.

На чертеже показано предлагаемое устройство .The drawing shows the proposed device.

Устройство дл удалени изделий из рабочей зоны пресса содержит корпус 1, закрепленный на станине 2 пресса. В расточках корпуса на ос х 3 и 4 смонтированыA device for removing articles from the working area of the press comprises a housing 1 fixed to the base 2 of the press. In the bores of the hull on the axis x 3 and 4 are mounted

двуплечие рычаги 5 и 6, смежные плечи которых шарнирно соединены между собой т гой 7. На свободном конце рычага б установлен ролик 8, посто нно взаимодействующий с профилем кулака 9 приводного валаtwo shoulders levers 5 and 6, the adjacent arms of which are pivotally connected to each other by a hard 7. At the free end of the lever b a roller 8 is installed, which constantly interacts with the profile of the fist 9 of the drive shaft

10 под действием усили пружины 11. Верхний конец рычага 5 осью 12 соединен с удал ющим щибером 13, свободный конец которого снабжен выступом и под действием пружины 14 посто нно поджат к зеркалу матрицы 15 нижней части штампа 16, установленной на ползуне 17 пресса. В матрице 15 размещены выталкиватель 18, взаимодействующий через толкатели 19 с порщнем 20 механизма противоприжима и пуансон 21.10 under the action of the force of the spring 11. The upper end of the lever 5 is connected by an axis 12 to the removal pin 13, the free end of which is provided with a protrusion and under the action of the spring 14 is constantly pressed against the mirror of the matrix 15 of the lower part of the die 16 mounted on the press ram 17. In the matrix 15 placed the ejector 18, interacting through the pushers 19 with a piston counter mechanism 20 and a punch 21.

Claims

The upper part of the shtampa 22 is fixed to the press frame and contains a punch-matrix 23, a pressure ring 24 and an ejector 25, which interacts through the pusher 26 with the piston 27 of the press-pressing mechanism. Processed strip 28 in the process of feeding slides on the plane of the clamping ring 24 of the upper part of the stamp. The lower part of the stamp 16 has bevels to which the tray 29 for receiving the cutouts 30 and the tray 31 for receiving the cut parts 32 are attached. A device for removing products from the working area of the press works as follows. When the slide 17 moves upwards, the lever 5 rotates clockwise under the action of the force of the spring 11, and the protrusion of the removing gate 13 slides along the mirror of the matrix 15 in the direction from left to right, moving the part 32 ejected from the matrix 15 to the tray 31. In the upper position of the slide the cutting process is carried out, with the lever system taking the position shown by the dotted line. At the beginning of the stroke of the slider 17 downwardly, the piston 27 pushes the cutting out of the matrix punch 23, which through the hole punched in the strip 28 falls onto the mirror of the matrix 15. As the slider continues downward, the gate 13 moves down from the cam 9 from right to left, while being pushed out of the top of the die part 30, the die cut 30 is removed by removing the gate into the receiving tray 29, and the die cut 32 remains pressed in the die and does not prevent the cutting out. When the slider reaches the lower position, when the removing spike 13 occupies the extreme left position, the piston 20 of the part 32 ejects from the matrix 15, which is removed to the receiving tray 31 by the slide 13 during the subsequent sliding of the slide. Next, the strip 28 is fed to the step and the cycle repeats. Apparatus of the Invention A device for removing articles from a working area of a press, comprising a removal chuck, fitted with a spring and hinged at the end of the lever, hinged on the stationary part of the press and kinematically connected with the movable part, characterized in that, in order to be able to remove waste gate by an amount greater than the stroke of the press slide, a projection is made at the free end of the gate from the die side, which constantly interacts with the die mirror and the lever is connected to the drive shaft the press through a system of levers and a cam mounted on the drive shaft.
