Beading machine
A beading machine is a device for forming straight bulges on a straight sheet metal or on tubes made of sheet metal ( beads ).
It consists of two rollers , one of which has the positive shape, the other the negative shape of the bulges. These rollers are usually interchangeable.
The sheet is inserted between the rollers. Then one or both rollers are set in motion (manually or by a motor ) and the sheet is pulled through.
While the rollers pull the sheet metal through the machine, the upper roller is gradually advanced, which causes more and more deformation (bead depth). In simple machines, the upper roller is infeed manually. Modern production machines use a motor for this.
automation
Program-controlled beading machines learn the workflow from the operator. Before the user creates the first part of an order, he presses a 'Learn' button on the machine. The control of the beading machine then registers when and how far the operator feeds the upper roller in the workflow. As soon as the user inserts the second workpiece in the order, the beading machine automatically repeats the entire process. The machine operator only has to guide the part and determine the variable working speed with the foot switch.
