Formed Sheet Metal Flanges

Figure 6 these blocks are made in pairs and are designed specifically for the shape of the area being formed.

Formed sheet metal flanges.

Clampco ensures that flanges and couplings are a perfect match. Forming metal is taking a flat or partially formed sheet metal blank and forming it into a desired shape. 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. The only tool you need is a length of 1 2 steel rod about 6 or so long.

Flanging metal is the act of swiping sheet metal in a direction contrary to its previous position. 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. Our formed sheet metal flanges are made from 301 302 or 304 stainless steel.

At the corner the flange lengths can either overlap underlap or butt. 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. Such parts are shaped with the aid of hardwood or metal forming blocks. The concave flange is formed by stretching while the convex flange is formed by shrinking.

In the end of this rod a slot is cut the. Forming a sheet metal flange. 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. The fab shop s main concern with corners is the sheet metal s memory.

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. There are many different kinds of mechanical stamping dies and some are designed primarily to form or flange sheet metal. Tonnage for air bending aisi 1035 based on 60 000 psi tensile strength.
