Bending Steel Sheet Metal

0 017453 x 90 x 0 020 0 33 x 0 024 0 0438558984 inch bend allowance keep in mind that some metals are more brittle than others.

Bending steel sheet metal.

Choose a bend radius that matches your minimum bend. Otherwise the sheet metal is almost certain to shift as you bend it resulting in a bad bend. To clamp efficiently lay your sheet metal on the top surface of your straightedge with the drawn line perfectly aligned with the outside edge of the sheet metal. Mild steel 1 brake shear slip roll 1 metal forming 1.

This page also includes a link to a on line sheet metal bend allowance calculator. The process delivers highly accurate forming maintenance of thickness and tremendous finished component strength. Most sheet metal materials will conform to the calculations. A cutout or the edge of your flange to your bend.

Sheet metal calculator bend allowance equations and calculator. Mild steel 1 16 ga. Determine your minimum bend by measuring the distance from your closest feature i e. Sheet metal bending methods design tips k factor bending is one of the most common sheet metal fabrication operations.

Hot metal forming offers tighter bend radii in high carbon steel in degrees that might break the material in cold forming. Mild steel 2 12 ga. Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape. Stainless steel 1 14 ga.

Clamping your sheet metal to the straightedge is a must. Stainless steel 1 20 ga. 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. Bending a brittle metal beyond its limits could cause the metal to snap and break.

As an example if you want to bend 24 gauge sheet metal at a 90 angle the calculation would be. If you re bending 0 020 thick material use a 0 020 radius. This is done through the application of force on a workpiece.
