Basic explanation - press brake forming:

 Forming is the step in the fabrication process that transforms a flat sheet metal blank into a three dimensional bent shape. A press brake is a precision machine that is used to bend or form sheet metal. The press brake does this by using special tooling that exerts force on the sheet metal causing it to bend.

 Form tooling is installed in the press brake top and bottom rail and then tightly clamped into position. Stops or gages are set to control the positioning of the sheet metal blank between the form tooling, punch (top) and die (bottom). Once the sheet metal blank is in position the press brake is activated and the punch forces the sheet metal into the die thus bending the sheet metal. The angle and the dimension of the bend are measured and adjustments are made to the forming setup until the desired results are obtained.

Service Offered:

• Precision press brake forming, using material supported nesting front and back gage system.

• Small sheet metal banks are captivated and nested under the form tooling to control precisely how the blank is contacted by the top punch tooling during forming, this ensures accurate angles and dimensions.

• Multiple die sets can be installed so bent shapes can be formed complete in one sequence provided the parts are small enough.

Machine Capacity:

• Chicago model 135, 15 tons pressure, 48 inch bend length, material support front and back gaging system for accurate part nesting.

• There is a very large selection of brake tooling ready to satisfy most forming needs.
