Изобретение относитс к обработке металлов давлением и может быть использовано в заготовительных цехах машиностроительных заводов.The invention relates to the processing of metals by pressure and can be used in the procurement workshops of machine-building plants.

По основному авт. св. № 821085 известно поддерживающее устройство к ножницам дл резки листового материала на полосы , содержащее наклонный лоток, установ:. ленные на нем с возможностью взаимодействи с отрезаемыми полосами поворотные упрры и привод Но ворота упоров Г.According to the main author. St. No. 821085 known support device for scissors for cutting sheet material into strips, containing an inclined tray, set :. pivotal guards and a drive, but gates of stops G.

Недостатком известного устройства вл етс малый объем накоплени отрезаемых полос, что приводит при длительной смене заполненной тары на порожнюю к вынужденным просто м ножниц, а следовательно, к снижению производительности их работы.A disadvantage of the known device is a small amount of accumulation of cut strips, which, with a long change of filled containers to empty ones, simply leads to forced shears, and consequently, to a decrease in the productivity of their work.

Цель изобретени - повышение производительности работы ножниц путем обеспечени возможности накоплени отрезанных полос при смене тары.The purpose of the invention is to increase the productivity of the scissors by allowing the cut strips to accumulate when changing tare.

Указанна цель достигаетс тем, что в поддерживающем устройстве к ножницам дл резки листового материала на полосы наклонный лоток по длине выполнен секционным по числу поворотных упоров, секции лотка смещены по высоте одна относительно другой, а привод поворота каждого из упоров выполнен индивидуальным.This goal is achieved by the fact that in the supporting device to the shears for cutting sheet material into strips, the inclined tray is sectioned along the number of pivot stops, the sections of the tray are displaced in height one relative to another, and the rotational drive of each of the stops is individual.

На чертеже изображено поддерживающее устройство дл резки листового материала на полосы, общий вид. 5 Поддерживающее устройство к ножницам дл резки листового материала на полосы содержит наклонный лоток , выполнен , ный из смещённых друг относительно друга по-высоте секций 1 и 2, снабженных следовательно установленными поворотными относительно горизонтальной оси упорами 3 и 4. Упоры 3 и 4 привод тс в движение с помощью пневмоцилийдров 5 и 6 через систему рычагов и т г.The drawing shows a supporting device for cutting sheet material into strips, a general view. 5 The supporting device to the shears for cutting sheet material into strips contains an inclined tray, made of sections 1 and 2 that are displaced relative to each other in height, and which are therefore equipped with stops 3 and 4 that are rotatable relative to the horizontal axis. movement with the help of pneumatic cylinders 5 and 6 through a system of levers and t g.

Положение и взаимосв зь упоров обеспечивает поочередное взаимодействие их с отрезанной полосой.The position and interconnection of the stops ensures their alternate interaction with the cut strip.

Устройство работает следующим образом .The device works as follows.

Claims

The sheet 7 is fed into the scissors and the strip 10 is cut by the blades 8 J and 9, which is oriented and held by the stop 4. After the end of the cutting cycle, the stops 3 and 4 are automatically rotated with pneumatic cylinders 5 and 6. The cut off strip 10, under the action of its own weight, slides off the wall 3 of section I of the tray to the stop 4 of section 2 of the tray. At this time, the stop 4 becomes in the "Closed" position, stops the cut strip and orients it additionally with its own plane. During the next cutting cycle, the stop 3 will support the newly cut strip, and the strip held by the stop 4 will be dropped into the container 11. When changing the container 11 carried out after filling the container or changing the brand of the material being cut, the stop 4 is held in position The cues are “Closed and simultaneously perform the functions of an orienting abutment and a stopper support. The specified volume of the accumulator is provided by changing the height difference. The stop 3 continues to operate from the pneumatic cylinder 5 in the same mode. After changing the container 11, the stop 4 begins to work in conjunction with the stop 3, and policies 10 retained up to this point are discharged into the container. If necessary, additional accumulation, lanes 10 can be maintained using yiiopa. 3 on section 1 of the tray. To this end, the control of cylinder 5 is switched to manual mode. In the proposed device, the stops, alternately stopping the cut strip, moving along the inclined tray, and occasionally, if it did not turn on the tray at a small angle when moving from the o; i valve to another, orient it along its plane. The shift of the strip across the tray is not significant and depends on the distance between the stops. The use of the present invention allows an increase in the productivity of the shears by allowing the cut strips to accumulate when changing tare. Claims of the Invention A supporting device for scissors for cutting sheet material into strips according to ed. St. No. 821085, characterized in that, in order to increase the productivity of scissors by allowing the cut strips to accumulate when changing containers, the inclined tray is sectioned along the number of pivot stops along the length, the sections of the tray are offset relative to each other, and individual.
