Bending

The bending technology area includes all manner of machines and processes for bending sheet metal, including press brakes, folders, panel benders, corner formers, ironworkers, notchers, orbital formers, and roll benders. It also has information on accessories such as gauging and backgauging systems.

A grand unifying theory of press brake bending: Part II

October 28, 2015 | By Steve Benson

Radius bends—defined here as any bend with an inside radius greater than 125 percent of the material thickness—require careful calculation, not only because of their significant springback, but also because of the tooling these bends require. This includes the use of relieved dies.

Automatic crowning system added to press brake

October 7, 2015

Gasparini has introduced the X-Press press brake with ACSG active crowning. A sensor in the ram detects bowing. Cylinders in the table raise the die, while another sensor measures the height. When the two values are equal, punch and die are at the same distance, and the profile has a constant angle...
