Formed Sheet Metal Flanges

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.

Formed sheet metal flanges.

In the end of this rod a slot is cut the. At the corner the flange lengths can either overlap underlap or butt. The only tool you need is a length of 1 2 steel rod about 6 or so long. Such parts are shaped with the aid of hardwood or metal forming blocks.

The fab shop s main concern with corners is the sheet metal s memory. 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. The design allows the deep return flange to extend beyond the tool centerline providing sufficient clearance for metal to form properly. Tonnage for air bending aisi 1035 based on 60 000 psi tensile strength.

There are many different kinds of mechanical stamping dies and some are designed primarily to form or flange sheet metal. Figure 6 these blocks are made in pairs and are designed specifically for the shape of the area being formed. Spinning sometimes called spin forming is a metal forming process used to form cylindrical parts by rotating a piece of sheet metal while forces are applied to one side. Our formed sheet metal flanges are made from 301 302 or 304 stainless steel.

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. Flanging metal is the act of swiping sheet metal in a direction contrary to its previous position. Forming a sheet metal flange. Forming metal is taking a flat or partially formed sheet metal blank and forming it into a desired shape.

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. When two edge flanges intersect a corner is formed.
