Force Required To Bend Sheet Metal Folding

Being able to read a bend force chart is crucial for any brake press operator and sheet metal engineer.

Force required to bend sheet metal folding.

As a result the wipe die also determines the bend s inner radius. It is important to make sure that the sheet is properly pushed onto the wipe die. Discover all our calculation tools in the calculators section of the top menu. 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 gauge inside radius die opening and minimum flange length are all interconnected through different equations and relationships the air bend force. 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 total strength of bending of a sheet is directly proportional to the length of bending. A punch exerts force at the correct spot bending the sheet metal between.

The die ratio may be entered to calculate the die opening which is typically 6 to 18 times the sheet thickness. Air bending is a simple method of creating a bend without the need for lower die geometry. The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels. The sheet metal is supported by two surfaces a certain distance apart.

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.
