Abstract

The invention relates to a method for feeding a flexible metal sheet. made in the form of a thermo-bimetallic plate, and allows to increase the reliability of supply. The method includes forming sheets of sheets, deforming them, grabbing and separating the sheet from the formed foot. New is the fact that during the formation of the foot, the thermo-bimetallic sheets are placed homogeneous material to each other, and the deformation of the sheets is carried out before being gripped by their heating, and the heating is carried out before the two upper sheets of the foot release. 1 il.

The invention relates to the supply of a flexible metal sheet, in particular to the separation of bimetallic sheets, and can be used in the automation of technological processes for the manufacture, processing and assembly of bimetallic sheets and including; II. Their products.

1, of the invention is to increase the reliability of the supply of a flexible metal -rfjcKoro sheet, made in the form of (# 1 etl l c e to it is melting.

If the sheets are low, then the heaters are located all over it; Heaters are located in: depending on the size of the sheets on two or four sides of the foot.

The method of feeding the bimetallic sheet is carried out as follows.

Before laying the bimetallic sheets on the table 1, a stack of them is formed, the bimetallic sheets being laid: from an odor layer of bimetallic material to each other, after which they are deformed by heating them 4.

Due to the location of the bimetallic sheets in the stack with a homogeneous material to each other, the upper sheets 7 and 8 are bent in opposite directions, which leads to their uncoupling with the formation of a gap a between them, which is necessary for reliable

unhooking sheets. Heating of the foot is carried out before the at least two upper sheets of the foot are disengaged.

After the upper sheets are unhooked, the grip 5 is lowered and the upper sheet 7 is gripped by suction cups 6, after which the grip is lifted and the sheet 7 is separated from the foot 3.

Then raise the foot 3 using the table or lower the heating device 4 by one step.

The proposed method of separating the thermo-bimetallic sheets from the foot provides in comparison with the known methods of increasing the reliability of separating the sheet from the foot, because before grabbing and separating the top sheet from the foot, it is already deformed to form a gap between them and subsequent sheets they are heated to release of the sheets, which excludes the possibility of sticking of the subsequent sheet caused by the presence of an oil layer and fins along the edges of the sheets.

The proposed method is most expediently applied in the automation of technological processes for the manufacture, processing and assembly of bimetallic sheets and products including them in cases where the sheets in the foot are strongly coupled when the feet are pressed, i.e. when reliable sheet disengagement is required to separate the top sheet.
