extensive experience with precision press brake forming.
Basic explanation - press brake forming:
Forming is the step in the fabrication
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
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.
- Precision press brake forming, using material supported
nesting front and back gage system.
- Small sheet metal banks are captivated and nested under
form tooling to control precisely how the blank is contacted by the top
punch tooling during forming, this ensures accurate angles and
- Multiple die sets can be installed so bent
shapes can be formed complete in one sequence provided the parts are
- 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.
