Horizontal bending on the press brake

July 15, 2015 | By Greg Flaherty, Michael Sosnoski

With the right tooling, you can accomplish horizontal bending—that is, where the sheet remains horizontal during the bend cycle—on the press brake. In general, horizontal bending on the press brake is accomplished with either wiping tools or rotary-style tools.

The 4 pillars of press brake tonnage limits

May 3, 2015 | By Steve Benson

To ensure you always work within the tonnage limits of your press brake and tooling, first calculate how much tonnage you need. Second, identify your tooling’s load limits. Third, calculate the sinking tonnage limit, which, if exceeded, can embed tooling into the ram or bed. Fourth, determine your press brakes’ centerline load limit.

How an air bend turns sharp

April 30, 2015 | By Steve Benson

Why do air bends in cold-rolled steel turn sharp at an inside radius that’s about 63 percent the material thickness? It has to do with the relationship between forming forces and a material’s tensile and yield strength.

The different parts of panel bending

April 30, 2015 | By Kevin Bartels

Is producing a hem on a part more suitable for a panel bender or press brake? Does a part less than a foot long make sense for a panel bender? Can a box design with a 13-in. wall be done on a panel bender? Part designs help to reveal the answers to these questions.
