The metal plate is a common metal plate processing mode, and the metal plate is a comprehensive cold processing technology aiming at a metal sheet, and comprises shearing, punching, cutting, compounding, folding, riveting, splicing, edge pressing, forming and the like. Particularly, in the sheet metal part of the electronic and electric appliances, due to the installation and embedding requirements, a slotted hole is often formed on the sheet metal part, and the two sides are symmetrically subjected to edge pressing so as to be clamped and installed accurately. The current common processing mode is as follows: the continuous notching processing is carried out on the long-strip plate firstly, then the intermittent blank pressing processing is carried out on the long-strip plate, then the long-strip plate after blank pressing is cut, a plurality of sheet metal base plates are formed, and then the sheet metal parts are formed through the processing of bending, flanging and the like. At present, the conventional beading machine generally adopts continuous beading, so that intermittent beading is difficult to be carried out on a long plate, and the conventional beading machine cannot be used for finishing the process because the symmetry of the beading at two sides and the position requirement of opposite grooves are very high.
