The 4 pillars of press brake tonnage limits

May 3, 2015

By:

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:

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.

Minimum versus recommended inside bend radius

April 1, 2015

By:

A material’s minimum inside bend radius shows the smallest radius that’s physically possible in an air bend, though your machines and tooling may not be able to handle the tonnage. The recommended inside bend radius, such as those found on bend allowance charts for air bends, shows you what’s optimal in typical applications

Why buy new tooling for a sheet metal hand brake?

February 17, 2015

By:

When bending with a hand brake, you can use the tooling that came with the machine, but investing in a tool with a radius on the punch nose has its benefits.

Bending basics: Streamlining press brake setup

March 24, 2014

By:

Press brake setup is a critical part of doing any bending job correctly. By focusing on a few key areas—selection of tools and forming processes, easy-to-understand setup sheets, and ISO documentation—the press brake operator is in a much better position to succeed.

Bending basics: Why profound-radius bending is a different animal

January 27, 2014

By:

Large or profound-radius bends are those in which the inside bend radius exceeds eight times the material thickness, but is still too small to move to the plate roll. At this point, a press brake operator has to change his mindset before proceeding. This is not a typical bending job.

Bending Basics: The fundamentals of heavy bending

January 2, 2014

By:

When bending on a press brake, thicker and harder plates require larger minimum bend radii. Finding the true minimum bend radius for steel or aluminum plate requires a little research. Nonetheless, the answers are there, waiting for you to find them.

Bending Basics: Why tonnage matters

August 1, 2013

By:

Selecting the press brake and tooling for a job involves much more than just making sure there’s enough brute force. You need to calculate how much tonnage the job requires, then determine the best machine and tooling to handle the tonnage.

Bending Basics: Why do die angles change?

June 3, 2013

By:

In air forming, the bend angle does not depend exclusively on the angle of the die. So why does the die angle change? There are two separate but overlapping answers; one relates to narrow die openings, and the other pertains to larger dies.
