At present, on the basis of the folded dead edge structure, various styles of folded dead edge structures are derived. figure 1 The one shown in is one of the sheet metal parts, which has a dead edge a, and the dead edge a is bent outward at 90° to form a vertical edge b. Due to the obstruction of the vertical edge b, the sheet metal can be pressed Block c is pressed against a very small area (see figure 2 ), the sheet will slide sideways during flattening, making it difficult to flatten the sheet

Abstract

The invention relates to the technical field of metal plates, and in particular to an edge folding and pressing process. The edge folding and pressing process comprises three processes of folding, bending, and flattening; the processes of folding and bending share the same folding mould; and the process of flattening adopts a fattening mould. In the flattening process, an upper mould pressing block cannot be influenced by a vertical edge b and can completely press a metal plate, and a lower mould plate and a splicing block can clamp the metal plate by overturning the metal plate at 180 degreesand making the vertical edge b face downwards, so that the metal plate is prevented from sliding to the side surface when the metal plate is flattened, and the metal plate is flatted smoothly.

Description

technical field [0001] The invention relates to the technical field of sheet metal, in particular to a folding and pressing process. Background technique [0002] There is a very special structure in the structural design of sheet metal parts: folding and pressing the dead edge. First, use a 30-degree bending knife to fold the sheet metal sheet to 30 degrees, and then flatten the bent edge. At present, on the basis of the folded dead edge structure, various styles of folded dead edge structures are derived. figure 1 The one shown in is one of the sheet metal parts, which has a dead edge a, and the dead edge a is bent outward at 90° to form a vertical edge b. Due to the obstruction of the vertical edge b, the sheet metal can be pressed Block c is pressed against a very small area (see figure 2 ), the plate will slide sideways during flattening, making it difficult to flatten the plate. Contents of the invention [0003] The technical problem to be solved by the pres...
