Sheet Metal Bending

When the sheet metal bend is parallel to the direction of the fiber of the metal material cracks are likely to occur at the bend of the sheet metal and the bending strength is low and it is easy to break as shown in the following figure.

Sheet metal bending.

See the bending force chart for. To use the tables below. Choose a bend radius that matches your minimum bend. Hole distance from.

There exists a minimum flange length as stated already before. 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. Creating a change in the part s geometry. Determine your minimum bend by measuring the distance from your closest feature i e.

Sheet metal bending should be as perpendicular as possible to the direction of the metal fiber. Clamp your sheet metal in your vise. Place your forms in your vise. As this happens you gain a small amount of total length in your part.

Support your excess sheet. 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. A cutout or the edge of your. Sheet metal design tips for bending minimum flange length.

When the sheet metal is put through the process of bending the metal around the bend is deformed and stretched. Now that your forms are placed you should clamp your sheet between your form. Similar to other metal forming processes bending changes the shape of the work piece while the volume of material will remain the same. 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.
