Bending Steel Sheet Metal

Mild steel 1 16 ga.

Bending steel sheet metal.

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. If you have any questions or want to discuss your design contact us. Bending a brittle metal beyond its limits could cause the metal to snap and break. Most sheet metal materials will conform to the calculations.

The following illustration shows the equation calculation for determining the bend allowance when forming sheet metal. This page also includes a link to a on line sheet metal bend allowance calculator. Sheet metal bending methods design tips k factor bending is one of the most common sheet metal fabrication operations. Clamping your sheet metal to the straightedge is a must.

Otherwise the sheet metal is almost certain to shift as you bend it resulting in a bad bend. 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. If you re bending 0 020 thick material use a 0 020 radius. Mild steel 1 brake shear slip roll 1 metal forming 1.

The process delivers highly accurate forming maintenance of thickness and tremendous finished component strength. Determine your minimum bend by measuring the distance from your closest feature i e. For most applications with stainless steel or aluminum you can get away with a zero radius bend on anything under 0 050 thick. Sheet metal calculator bend allowance equations and calculator.

Hot metal forming offers tighter bend radii in high carbon steel in degrees that might break the material in cold forming. Choose a bend radius that matches your minimum bend. This is done through the application of force on a workpiece. Mild steel 2 12 ga.
