Formed Sheet Metal Flanges

Clampco ensures that flanges and couplings are a perfect match.

Formed sheet metal flanges.

Figure 6 these blocks are made in pairs and are designed specifically for the shape of the area being 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. Forming a sheet metal flange. 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.

In the end of this rod a slot is cut the. 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. The only tool you need is a length of 1 2 steel rod about 6 or so long.

There are many different kinds of mechanical stamping dies and some are designed primarily to form or flange sheet metal. At the corner the flange lengths can either overlap underlap or butt. 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. Tonnage for air bending aisi 1035 based on 60 000 psi tensile strength.

The design allows the deep return flange to extend beyond the tool centerline providing sufficient clearance for metal to form properly. Overbending each flange is necessary to allow it tospring back to the correct unrestrained angle. 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. Such parts are shaped with the aid of hardwood or metal forming blocks.

When two edge flanges intersect a corner is 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. Forming metal is taking a flat or partially formed sheet metal blank and forming it into a desired shape.
