Aluminim Bending is a manufacturing process that produces a V-shape, U-shape, or channel shape along a straight axis in ductile materials, most commonly sheet metal. Commonly used equipment include box and pan brakes, brake presses and other specialized machine presses. Typical products that are made through aluminium bending are boxes such as electrical enclosures and rectangular ductwork. A profile is guided between three adjustable bending rolls and gradually bent in the desired radius. Roll bending is the ideal bending method for profiles with complex designs and different radii. Kersten has become specialized in 3D roll bending.
A flexible fence is a specialized metalworking tool used to create precise linear bends and folds in thin sheet metal, such as that used to make door, window, and roof coverings. They consist of two long, thin platforms, one fixed and the other freely rotating. Pulling a pair of small handles rotates the moving platform upwards, bending the metal at different angles to the fixed platform.
Insert your aluminum sheet into the brake under the detachable support bar. Lift the support bar at the back of the brake frame and slide the sheet metal vertically in the direction you want to bend it. Then place the terminal block again in a cross shape on the aluminum. Make sure the bar is firmly seated in the frame.
Tip: It may be necessary to manually change the height of a non-detachable grab bar. You can usually do this by pulling a tab on one end of the brake and raising or lowering the bar as needed.
Adjust the edge of the sheet to create the desired fold line. Move the sheet within the brake as needed to align the fold point with the inside edge of the terminal strip (the side that faces forward). The sheet section below the clipboard is folded up and around this edge to create the fold.
To ensure a straight and accurate fold, check your blade to ensure the outside edge is parallel to the edge of the terminal block.
Attach a pair of C-Clamps to hold the wing in place. Place a clamp equidistant from either end of the clamp rod, then screw it into place. It is not necessary to place the clamps directly on the aluminum. They are only there to keep the clamp rod firmly attached to the brake pivot.
Some more expensive brake models have built-in clamps that can be pulled down on a or multiple handles.
Lift the handles on the skirt to fold the sheet to the desired angle. Go slowly: the aluminum foil is very soft, so you don't have to use a lot of force. As the apron rises, it gently folds the sheet around the edge of the grab handle at the chosen flex point. Continue pulling the handles up until the sheet is the desired shape.
The movement of the platform will stop automatically once the plate reaches a predetermined angle.
