Sheet Metal Bending

To use the tables below.

Sheet metal bending.

Bending your sheet metal with a vise 1. Choose a bend radius that matches your minimum bend. Sheet metal bending should be as perpendicular as possible to the direction of the metal fiber. Even on malleable materials you can end up cracking the metal at the bend or weakening it to the point where it ll break with minimal force.

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. When the sheet metal is put through the process of bending the metal around the bend is deformed and stretched. Creating a change in the part s geometry. Likewise when you are trying to develop a flat pattern you will have to make a deduction from your desired part size to get the correct flat size.

Place your forms in your vise. The solution is to have a radius on the tool that you ll be using to bend the metal. See the bending force chart for. As this happens you gain a small amount of total length in your part.

If you bend to a sharp inside corner with sheet metal you ll be adding a ton of internal stresses. If you want to make a flange that has one or two ends chamfered the previous rule of a minimum flange. Clamp your sheet metal in your vise. Support your excess sheet.

Determine your minimum bend by measuring the distance from your closest feature i e. Your forms will have an edge that should match the angle of your desired bend. Bending of sheet metal is a common and vital process in manufacturing industry. Sheet metal design tips for bending minimum flange length.

Similar to other metal forming processes bending changes the shape of the work piece while the volume of material will remain the same. Hole distance from.
