Abstract

Изобретение относитс к обработке металлов давлением, в частности к вспомогательному оборудованию заготовительного производства, и может быть использовано дл подачи заготовок в ножницы. Цель изобретени - улучшение условий эксплуатации. Перед началом работы устройства консоль переводитс в горизонтальное положение и фиксируетс с помощью гайки к кронштейну и регулируемого упора. Лист по рольгангу подаетс к ножницам. Включаетс электродвигатель 43, жестко закрепленный на плите. Вращение через предохранительную муфту 44, ведущий вал 45, установленный в вертикальной трубе 9 консоли 7, коническую передачу 48, 49 передаетс ведомому валу - винту 16, взаимодействующему с гайкой 50 каретки 17, перемеща ее по направл ющим, установленным в стойках 10 и 11, расположенных на горизонтальной трубе 8 консоли 7. Лист зажимаетс между зажимами рычага 21 и двуплечего рычага 34 и перемещаетс с помощью устройства до тех пор, пока не останетс концевой остаток листа 32, и каретка 17 не остановитс . Включаютс ножницы, и происходит резка. Отход концевого остатка падает в тару. Размещение каретки с поворотными захватами и привода перемещени каретки на поворотной консоли позвол ет отводить устройство в исходное положение и не мешает работе ножниц. 3 з.п. ф-лы, 8 ил.The invention relates to the processing of metals by pressure, in particular to the auxiliary equipment of the blank production, and can be used to feed the blanks into scissors. The purpose of the invention is to improve the operating conditions. Before operating the device, the console is moved to a horizontal position and fixed with a nut to the bracket and an adjustable stop. Roller sheet is fed to the scissors. An electric motor 43, rigidly mounted on the plate, is turned on. The rotation through the safety coupling 44, the drive shaft 45, mounted in the vertical pipe 9 of the console 7, the bevel gear 48, 49 is transmitted to the driven shaft-screw 16, cooperating with the nut 50 of the carriage 17, moving it along rails installed in racks 10 and 11, located on the horizontal pipe 8 of the console 7. The sheet is clamped between the clips of the lever 21 and the two shoulders lever 34 and is moved by the device until the end residue of the sheet 32 remains and the carriage 17 stops. Scissors are turned on and cutting takes place. Waste end residue falls into the container. Placing the carriage with swivel grips and a drive for moving the carriage to the swivel cantilever allows the device to retract to its original position and does not interfere with the operation of the scissors. 3 hp f-ly, 8 ill.

Claims

Claim

1. A device for feeding sheet blanks containing a plate, guides arranged perpendicular to the cutting plane and supporting the carriage with two pivoting grips made in the form of levers with supporting surfaces, a carriage drive and stops for restricting carriage movement mounted on the guides, characterized in that, in order to improve operating conditions, it is equipped with a console pivotally connected to the plate with the possibility of rotation and its fixation in a horizontal plane, made in the form of coal a, formed by vertical and horizontal pipes, and racks located on the horizontal tube of the console, while the movement drive is mounted on the plate and made in the form of an electric motor, coupling) of the drive shaft, bevel gear and driven shaft screw, while the drive shaft of the carriage is located in the vertical tube of the console, and the guides and the driven shaft-screw of the carriage displacement drive, located at equal distances between the guides with the possibility of interaction with the nut mounted on the carriage, mounted in racks.

2. The device according to π. 1, characterized in that, in order to increase the reliability of fixing the console in a horizontal plane, it is equipped with a bracket rigidly mounted on the plate, with an adjustable stop and a hinged screw with a nut pivotally mounted on the bracket, the console is made with an eye, and the hinged screw is installed with the ability to interact with the eye.

3. The device according to π. 1, characterized in that the stops restricting the movement of the carriage are made in the form of clamps and mounted on rails.

4. The device according to π. 1, characterized in that each rotary grip is equipped with an additional lever, the axis of rotation of which is mounted on the main lever, a cracker mounted on one shoulder of the additional lever, and a power cylinder rigidly mounted on the other shoulder of the additional lever, while the rod of the power cylinder is mounted with the possibility interactions with the main lever.
