Formed Sheet Metal Flanges

Our formed sheet metal flanges are made from 301 302 or 304 stainless steel.

Formed sheet metal flanges.

Figure 1 a side view of a formed sheet shows how the vertical extension flange on the top becomes a deep return flange after the second bend shown at the bottom. When two edge flanges intersect a corner is formed. The only tool you need is a length of 1 2 steel rod about 6 or so long. Tonnage for air bending aisi 1035 based on 60 000 psi tensile strength.

In days gone by when most bodywork was done by skilled tinsmiths with no modern machinery many methods of working existed which have largely been forgotten now this is possibly one of them. A sheet metal disc is rotated at high speeds while rollers press the sheet against a tool called a mandrel to form the shape of the desired part. Forming a sheet metal flange. At the corner the flange lengths can either overlap underlap or butt.

Flanging metal is the act of swiping sheet metal in a direction contrary to its previous position. The fab shop s main concern with corners is the sheet metal s memory. Clampco formed sheet metal flanges can be used in a variety of pairings including two formed sheet metal flanges or a combination of a formed sheet metal flange and a machined flange. Figure 6 these blocks are made in pairs and are designed specifically for the shape of the area being formed.

The concave flange is formed by stretching while the convex flange is formed by shrinking. Such parts are shaped with the aid of hardwood or metal forming blocks. The design allows the deep return flange to extend beyond the tool centerline providing sufficient clearance for metal to form properly. Forming metal is taking a flat or partially formed sheet metal blank and forming it into a desired shape.

Reliefs a relief is a tool modification that allows a deep return flange to move into an area where the punch body would otherwise be. Overbending each flange is necessary to allow it tospring back to the correct unrestrained angle. Clampco ensures that flanges and couplings are a perfect match.
