Description

one

The invention relates to automation of sheet metal forming and can be used to feed sheet blanks into a working area of a press or other processing equipment for processing sheet blanks.

A device for separating a sheet blank from the foot is known, comprising a table for placing a foot, a movable yoke with suction cups located above it, and an emphasis made in the form of a rack and lifted up with the edge of the upper sheet blank. The stop is laid at that distance from the table with the foot, that the ends of the sheets, the overhang from the table, rest against it, with the stop teeth located below the level of the upper sheet of the foot.

The disadvantages of the known device are that it can only work with a rather thin Material, which, when bent under its own weight, forms a loop, and also that due to the adhesion of burrs and preservative lubrication, the loop can be formed not one but two or more stuck with blanks and in this

case there will be no separation of one billet. In addition, in the known device difficult laying of the foot blanks on the table

It is also known a device for separating sheet blanks from the foot, which contains a table for placing the foot, vacuum suckers located above it, and a spring stop installed above the level of the upper sheet of the foot and preventing more than one workpiece from entering the treatment area when moving them around.

This device can also be used only for fairly thick workpieces, in addition, it has relatively large dimensions, and laying the foot in this device is difficult.

The purpose of the invention is to increase the reliability of separating the workpiece from the foot and to facilitate laying the foot on the table.

This is achieved by the fact that the emphasis in the described device is installed with the possibility of moving in the direction of the pair; table plane, and is equipped with a spring, Gujijakia ECO kr (KR aaiirruBKti, and pgo tooth}) is more than 1Y higher than the stop level

The ostrystvo can also be equipped with the first corner of the first corner {) ohm, performed similarly to the first TI ycTanofiJie) (taxically with him but D1) to the side of the foot

fia FIG. 1 shows the proposed device, side view; in fig. 2 view A of FIG. FIG. 3, node I of FIG. 1;

The device contains table 1, along edges

the supports of which are fixed 2. fia stands are higher than the level of the upper blank of the foot, on two sides opposite to the foot, stops 3 are installed, made in the form of toothed racks. The stops c) are abraded by springs 4 and located on the guides 5. In the uprights and rails there are holes 6 serving to fix the slats in a position apart from the table with the foot. Fix the slats using pins (not shown). A traverse 7 is installed above the barrel, on which vacuum suction devices 8 are located. Next to the table is a roller table 9 and feed rollers 10 for feeding sheet blanks to a press 11 The device works as follows

The gear racks are pushed along the rails until they are flush with the posts and fixed with pins through the holes 6. Then a stack of baffles is placed on the table, releasing the rails and they are moved by springs to the working position. They lower the traverse with vacuum suckers onto the foot of the rotoBOK. When lifting the traverse, the suction cups hold one or several blanks. When the blanks contact with the gear racks, their ends are bent; ,Availability
