Bending Steel Sheet Metal

Determine your minimum bend by measuring the distance from your closest feature i e.

Bending steel sheet metal.

Mild steel 1 brake shear slip roll 1 metal forming 1. Stainless steel 1 20 ga. Clamping your sheet metal to the straightedge is a must. Choose a bend radius that matches your minimum bend.

Mild steel 2 12 ga. If you have any questions or want to discuss your design contact us. If you re bending 0 020 thick material use a 0 020 radius. Stainless steel 1 14 ga.

Sheet metal calculator bend allowance equations and calculator. The process delivers highly accurate forming maintenance of thickness and tremendous finished component strength. Sheet metal bending methods design tips k factor 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.

A cutout or the edge of your flange to your bend. Hot metal forming offers tighter bend radii in high carbon steel in degrees that might break the material in cold forming. Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape. For most applications with stainless steel or aluminum you can get away with a zero radius bend on anything under 0 050 thick.

Otherwise the sheet metal is almost certain to shift as you bend it resulting in a bad bend. The following illustration shows the equation calculation for determining the bend allowance when forming sheet metal. Mild steel 1 16 ga. 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.

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. This page also includes a link to a on line sheet metal bend allowance calculator. Bending a brittle metal beyond its limits could cause the metal to snap and break.
