Bending A Curve In Sheet Metal

The inside bend radius should be equal to the thickness of the material that you re forming.

Bending a curve in sheet metal.

Sheet metal bending is the plastic deformation of the work over an axis creating a change in the part s geometry. To think about bending a sheet of metal that has appreciable thickness focus on an imaginary central sheet the so called neutral line or neutral axis within the thickness. Finally bend the sheet up by hand to the angle desired. This applied force is also called the bending moment.

This is done through the application of force on a workpiece. Bending sheet metal by hand is a manageable task if the piece of sheet metal is small and thin enough to handle. Clamp the wood on top of the metal to the workbench. Most frequently expensive sheet metal bending tools called brakes are used to bend sheet metal but you can also complete this task without one.

The force of the bending moment determines the degree of deformation. The force must exceed the material s yield strength to achieve a plastic deformation. Make sure the first bend mark lines up exactly with the curve in the form so that the bending will begin in the right spot. Bending is one of the most common sheet metal fabrication operations.

In other words if you re bending 1 8 sheet use a tool with a 1 8 radius to form the inside of the bend. Next place the wood parallel and slightly behind the bending line. If you want a sharp 90 bend tap along the crease with a mallet. Using protective gloves hold the free end of the metal sheet with one hand and with the other hand use a mallet or hammer to begin bending the sheet down and around the curved radius of the wood form.

Sheet metal bending bending of sheet metal is a common and vital process in manufacturing industry. Mark a bend line and place the sheet metal on the edge of your bench. Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape.
