Force Required To Bend Sheet Metal Folding

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. 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 slack between the wipe die and the punch plays an important role in getting a good result.

The die ratio may be entered to calculate the die opening which is typically 6 to 18 times the sheet thickness. A punch exerts force at the correct spot bending the sheet metal between. The total strength of bending of a sheet is directly proportional to the length of bending. 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 tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels. 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. Wipe bending or edge bending is another way to bend sheet metal edges. The gauge inside radius die opening and minimum flange length are all interconnected through different equations and relationships the air bend force.

The strength of the table is the force required to bend sheet metal up to 1 m in length. It is important to make sure that the sheet is properly pushed onto the wipe die. The sheet metal is supported by two surfaces a certain distance apart.
