Force Required To Bend Sheet Metal Folding

Wipe bending or edge bending is another way to bend sheet metal edges.

Force required to bend sheet metal folding. The slack between the wipe die and the punch plays an important role in getting a good result. To define the bend region and reduce the force required to bend a part out of sheet metal down to something you can handle without a brake press slots can be cut at the bending line to. The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels. The strength of the table is the force required to bend sheet metal up to 1 m in length.

This tool allows you to determine tonnage internal radius v die opening and minimum flange you just have to insert the characteristics of the sheet metal to be bent. The bending force can be calculated from the sheet thickness die opening bend length and the ultimate tensile strength of the material. As a result the wipe die also determines the bend s inner radius. The total strength of bending of a sheet is directly proportional to the length of bending.

Air bending is a simple method of creating a bend without the need for lower die geometry. The sheet metal is supported by two surfaces a certain distance apart. A punch exerts force at the correct spot bending the sheet metal between. An air bend force chart or force chart breaks down a number of key components of sheet metal bending in an easy to reference format.

It is important to make sure that the sheet is properly pushed onto the wipe die. Being able to read a bend force chart is crucial for any brake press operator and sheet metal engineer.
