Изобретение относитс к кузнечно-прессовому машиностроению и может быть использовано дл отделени верхнего листа от стопы и подачи его к прессу.The invention relates to forging and pressing machinery and can be used to separate the top sheet from the foot and feed it to the press.

Известно устройство дл отделени верхнего листа от стопы и подачи его к прессу, содержащее подъемный стол дл стопы листов и расположенные над ним направл ющие дл перемещени приводной каретки, на- которой смонтированы захватные органы 1.A device for separating the top sheet from the foot and delivering it to the press is known, comprising a lifting table for the sheet of sheets and guides located above it for moving the drive carriage, on which the gripping bodies 1 are mounted.

Известно также устройство дл отделени верхнего листа от стопы и подачи его к прессу, содержащее установленный на основании магазин дл стопы листов и расположенные над ним направл ющие дл перемещени приводной каретки, на которой консольно закреплена балка, несуща , по меньшей мере, два захватных органа 2.It is also known a device for separating the top sheet from the foot and supplying it to the press, comprising a sheet-mounted magazine for the stack of sheets and guides above it for moving the drive carriage onto which the beam carrying at least two gripping bodies 2 .

Эти устройства не обеспечивают достаточно надежного отделени верхнего листа от стопы.These devices do not provide sufficiently reliable separation of the top sheet from the foot.

Цель изобретени - ловышение надежности отделени листа от стопы.The purpose of the invention is to increase the reliability of separation of the sheet from the foot.

Поставленна цель достигаетс тем, что каждый из захватных органов выполнен в виде закрепленного на балке стержн иThe goal is achieved by the fact that each of the gripping bodies is made in the form of a rod fixed on the beam and

свободно установленной на нем подпружиненной в направлении стопы листов втулки, на боковой стороне которой выполнен выступ, а со стороны стопы листов установлена регулировочна гайка ножевой пластины, закрепленной на выступе с образованием зазора между ее верхней плоскостью и нижним торцом регулировочной гайки.free-installed spring-loaded sleeve in the direction of the foot of the sheet;

На балке может быть закреплен двуплечий рычаг, каждый конец которого щарнирно св зан при помощи рычага с выступом одной из втулок.A double-arm lever can be attached to the beam, each end of which is pivotally connected by means of a lever with a protrusion of one of the sleeves.

С целью обеспечени возможности удалени обработанного листа из рабочей зоны пресса, на свободном конце балки закреплены толкатели.In order to ensure the possibility of removing the processed sheet from the working area of the press, pushers are fixed at the free end of the beam.

На выступе одной из втулок может быть установлена ручка с фиксатором, взаимодействующим с балкой.On the ledge of one of the sleeves can be installed handle with a latch, interacting with the beam.

Магазин установлен на стойках, а под ним смонтирован подъемный стол дл подъема стопы листов.The magazine is mounted on racks, and under it is mounted a lifting table for lifting a stack of sheets.

Claims

FIG. 1 shows the proposed device, a general view; in fig. 2 is a view A of FIG. one; in fig. 3 - gripping body, longitudinal section. The device for separating the top sheet from the foot and feeding it to the press contains a frame 1 on which rack 2 is fixed. Stand 2 has a magazine 3 for a stack of blanks 4. A lifting table 5 equipped with a mechanism 6 is also mounted on the frame 1. For the passage of the lifting table 5, a hole is made in the bottom of the store 3 (not shown). Above the lifting table 5, guides 7 are mounted on the frame 8, and a carriage 9 is installed on them with supports 10 for rolling. The frame 8 is mounted on the trolley 11. On the carriage 9 is pivotally mounted a power cylinder 12, on the rod of which gear wheel 13. Gear 13 is engaged with gear rack 14 mounted on the frame 8 and gear rack 15 mounted on the carriage 9. On the carriage 9 is fixed at one end of the beam 16, on the other end, perpendicular to the axis of the beam 16, the bar 17 is fixed. At the ends of the bar 17, the pushers 18 are mounted. On the beam 16, between the bar 17 and the carriage 9, the bar 19 is fixed, and on each of its ends are mounted brackets 20 with a gripping body. Each of the gripping bodies is made in the form of a vertically mounted rod 21 fixed in the bracket 20, on which 22 is freely mounted, carrying a knife plate 23 located parallel to the plane of the lower end of the nut 24 screwed onto the sleeve 22. At the end of each rod 21 there is a shoulder. A spherical washer 25 is installed on the bars 21 between the shoulder and the sleeve 22. A bar 26, a spherical washer 27 and a spring 28 are freely mounted on each bar 21. A spring-loaded retainer 29, which is included in the bar 30, is mounted on one of the bushings 22. The latch 29 is connected with the handle 31. The knife plates 23 and the clamps 29 are fixed on the protrusions 32 made on the sleeves 22. On the beam 16 or on the bar 19 a double-arm lever 33 is hinged, each end of which is connected to one through the lever 34 from the tabs 32. The device is installed Press 35, which is fixed on the table 36 for die stamping parts 37. Between the press 35 and the lifting table 5 is mounted tray 38. The apparatus operates as follows. Store 3 with a stack of sheet blanks 4 is mounted on racks 2. Cart 11 is brought to lift table 5 and attached to frame 1. Lifting mechanism 6 lifts table 5, and it through the hole in the bottom of store 3 acts on the stack of sheet blanks 4 and lifts its to the final switch (not shown). Then, the clamp 29 is pushed into the hole 30 of the strip 26 and the sleeve 22 is fixed in a predetermined position. At the same time, the sleeve 22, through the levers 34 and the double-arm lever 33, also rotates on the rod 21 and is fixed in a predetermined position. The knife plates 23 are brought under the upper sheet of the foot 4. At the same time, the distance e between the lower end of the nut 24 and the knife plate 23 is 0.3 mm thicker than the sheet, which guarantees separation of only one sheet from the foot. The power cylinder 12 is turned on, and through gear 13 and gear racks 14 and 15 it drives the carriage 9 along the guides 7. The carriage 9 moves the separated sheet from the foot into the working area of the press 35, and the pushers 18 push the grinding part 37 from the chipboard 36 When the carriage 9 returns to its initial position, the actuator 6 moves the table 5 up to a height equal to the thickness of the sheet. Then the cycle is repeated. Claim 1. Device for separating the top sheet from the foot and supplying it to the press, containing a foot magazine installed on the base and guides located above it for moving the drive carriage on which the beam supporting at least two gripping bodies , characterized in that, in order to increase the reliability of separating the sheet from the foot, each of the gripping bodies is made in the form of a rod fixed on the beam and a sheet which is spring-loaded in the direction of the foot; bushings, on the side where the protrusion is formed, and from the stack of sheets set adjusting nut, cutter plate fixed to the ledge to form a gap between the upper plane and the lower face of the adjusting nut. 2.
