In sheet metal fabrication, bending is commonly used to produce V-shapes, U-shapes, and channel shapes along straight axes. Press brakes are specialized machines that are used for this process. A lower die and an upper die are used to bend sheet metal on these machines. In the next step, the sheet metal is formed into the desired shape.Among the shapes that can be formed by bending machines are curves, angles, and circles. Their ability to produce parts with a high degree of accuracy and consistency is impressive.
Air bending, bottoming, and coining are among the bending techniques that can be performed using this equipment. Air bending is the most common type of bending and is most effective for large parts.
Automotive or aircraft panels, electrical enclosures, storage units, cabinets, and many other types of products are bent by many manufacturers. A hydraulic press and a press brake are also used as part of this process.
In low to medium quantities, bending produces lightweight parts with good mechanical properties. A relatively simple process, it only requires minimal equipment and basic operator skills. Sheet metal can also be formed into complex shapes using this method.
