Formed Sheet Metal Flanges

The only tool you need is a length of 1 2 steel rod about 6 or so long.

Formed sheet metal flanges. Our formed sheet metal flanges are made from 301 302 or 304 stainless steel. 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. Forming metal is taking a flat or partially formed sheet metal blank and forming it into a desired shape. Such parts are shaped with the aid of hardwood or metal forming blocks.

Figure 6 these blocks are made in pairs and are designed specifically for the shape of the area being formed. 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. Clampco ensures that flanges and couplings are a perfect match. Flanging metal is the act of swiping sheet metal in a direction contrary to its previous position.

Tonnage for air bending aisi 1035 based on 60 000 psi tensile strength. When two edge flanges intersect a corner is formed. 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. There are many different kinds of mechanical stamping dies and some are designed primarily to form or flange sheet metal.

The design allows the deep return flange to extend beyond the tool centerline providing sufficient clearance for metal to form properly. The concave flange is formed by stretching while the convex flange is formed by shrinking. Forming a sheet metal flange. 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.

In the end of this rod a slot is cut the. 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. At the corner the flange lengths can either overlap underlap or butt.
