Formed Sheet Metal Flanges

Successful sheet metal forming relies heavily on the metal s mechanical properties.

Formed sheet metal flanges.

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. 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 applied force stresses the metal beyond its yield strength causing the material to plastically deform but not to fail.

Forming a sheet metal flange. Most part defects such as splits and wrinkles occur in forming operations. Our formed sheet metal flanges are made from 301 302 or 304 stainless steel. 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. In the end of this rod a slot is cut the. Sheet metal forming processes are those in which force is applied to a piece of sheet metal to modify its geometry rather than remove any material. The only tool you need is a length of 1 2 steel rod about 6 or so long.

Figure 6 these blocks are made in pairs and are designed specifically for the shape of the area being formed. By doing so the sheet can be bent or stretched into a variety of complex shapes. The metal being formed must have the ability to stretch and compress within given limits. There are many different kinds of mechanical stamping dies and some are designed primarily to form or flange sheet metal.

The concave flange is formed by stretching while the convex flange is formed by shrinking. When two edge flanges intersect a corner is formed. At the corner the flange lengths can either overlap underlap or butt. Forming a sheet metal blank into the shape required by design is.
