Force required to bend sheet metal folding.
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.
The die ratio may be entered to calculate the die opening which is typically 6 to 18 times the sheet thickness.
The slack between the wipe die and the punch plays an important role in getting a good result.
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 strength of the table is the force required to bend sheet metal up to 1 m in length.
As a result the wipe die also determines the bend s inner radius.
The gauge inside radius die opening and minimum flange length are all interconnected through different equations and relationships the air bend force.
Air bending is a simple method of creating a bend without the need for lower die geometry.
The bending force can be calculated from the sheet thickness die opening bend length and the ultimate tensile strength of the material.
The total strength of bending of a sheet is directly proportional to the length of bending.
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.
Being able to read a bend force chart is crucial for any brake press operator and sheet metal engineer.
Wipe bending or edge bending is another way to bend sheet metal edges.

It is important to make sure that the sheet is properly pushed onto the wipe die.
