Safety procedures for bending machines.

The Basic 90º BendPress brake bending falls into two basic categories with several compromise options. The first is the foundation for all press brake work and is called air bending. The second type is called bottom bending. A) Air Bending Air bending is defined as three points of contact with the p

The bending machine is an important equipment for bending and forming the workpiece in the sheet metal industry. Its function is to press the steel plate into various shapes according to the process requirements. Figure 1 shows the structure of the hydraulic sheet metal bending machine.

Maintained and operated properly, old brakes still can produce good partsFigure 1 If your dial indicator reading gets larger and then smaller as it’s moved along the bed, the brake is suffering from ram upset.Question: I have been reading your columns for years and I have found them to be a wealth o

Predicting the radius is never 100 percent accurate, but this is about as good as it getsYou can use some common rules of thumb to predict the inside bend radius when air forming, and the results you get are usually close enough, but with the help of a few online calculators, you can get even closer
