Thick Sheet Metal Bending

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

Thick sheet metal bending.

If you have any questions or want to discuss your design contact us. The force must exceed the material s yield strength to achieve a plastic deformation. Choose a bend radius that matches your minimum bend. Bending is one of the most common sheet metal fabrication operations.

The important factors influencing the mechanics of bending are material sheet thickness width over which bend occurs radius of bend bend angle machinery tooling and specific metal bending process. In steel between 0 5 and 0 8 in. The largest variations come from the materials themselves. The bend radius refers to the inside radius.

How to bend sheet metal without a brake. Thick grade 350 and 400 may have a minimum bend radius of 2 5 times the material thickness when transverse bending. The bend deduction is the amount the sheet metal will stretch when bent as measured from the outside edges of the bend. Bending a sheet will create forces that act in the bend region and through the thickness of the sheet.

When sheet metal is bent it stretches in length. Again the minimum inside bend radius is even larger when bending with the grain. Unfortunately sheet metal bending is not always going to be the same in every shop. 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.

Keep in mind that many kinds of fabricated metal have extremely high melting points and applying your torch injudiciously could cause damage or do harm to your sheet metal or equipment. Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape. In the event that you are bending a thick piece of sheet metal you can apply heat from a blowtorch along the seam of your bend line to facilitate your bend. A cutout or the edge of your flange to your bend.

If you re bending 0 020 thick material use a 0 020 radius. The formed bend radius is dependent upon the dies used the material properties and the material thickness. The inside bend radius should be equal to the thickness of the material that you re forming. This is done through the application of force on a workpiece.

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. We are here to help.
