Formed Sheet Metal Flanges

The fab shop s main concern with corners is the sheet metal s memory.

Formed sheet metal flanges.

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

When two edge flanges intersect a corner is formed. The concave flange is formed by stretching while the convex flange is formed by shrinking. Clampco ensures that flanges and couplings are a perfect match. 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.

The design allows the deep return flange to extend beyond the tool centerline providing sufficient clearance for metal to form properly. Forming a sheet metal flange. Tonnage for air bending aisi 1035 based on 60 000 psi tensile strength. The only tool you need is a length of 1 2 steel rod about 6 or so long.

Our formed sheet metal flanges are made from 301 302 or 304 stainless steel. In the end of this rod a slot is cut the. Such parts are shaped with the aid of hardwood or metal forming blocks. 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.

At the corner the flange lengths can either overlap underlap or butt. There are many different kinds of mechanical stamping dies and some are designed primarily to form or flange sheet metal. Overbending each flange is necessary to allow it tospring back to the correct unrestrained angle.
