Fold Sheet Metal Edge Over

Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape.

Fold sheet metal edge over.

The benefits of working with beveltools. This is done through the application of force on a workpiece. Create a bend with acute angle tooling in the metal 30 is preferable but 45 will work for some circumstances. In sheet metal hemming means to fold the metal back on itself.

How large of a bend you put in the metal depends on the application and fitment of the piece. Folding over the edge of a piece of sheet metal will give the metal instant structural integrity. With care and patience full size sheets of aluminium can be cut using this method. Sheet metal bending is the plastic deformation of the work over an axis creating a change in the part s geometry.

Mark your bend lines. Similar to tucking the corners of a bedsheet these benders twist and wrap the metal into triangle shaped folds to form corners. Place the fracture line over the edge of a table and bend the overhang slightly downwards. This is how easy it is to make a rounded edge on metal.

Bending of sheet metal is a common and vital process in manufacturing industry. The force must exceed the material s yield strength to achieve a plastic deformation. Bending is one of the most common sheet metal fabrication operations. Similar to other metal forming processes bending changes the shape of the work piece while the volume of material will remain the same.

Now that you know your bend allowance take your protractor and draw a clear line with your marker across the point at which you will bend your sheet metal. Then use your bend allowance to draw your second bend line the intervening distance between your bend lines bend radius. After a few wiggles the sheet will fracture along the cut line leaving a clean break as shown in the above photos. Flip the sheet over and repeat.

If you re just trying to strengthen a panel a broken edge as small as inch wide can make a big difference in the strength of the panel. When working with a brake press hems are always created in a two step process. Economy sheet metal benders make bends up to 90 in metal sheets.
