The fundamentals of heavy bending
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.
Why tonnage matters
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.
Why do die angles change
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.
Finding the perfect die opening
By choosing a die opening as close to perfect as possible, your consistency will improve, your setup and run times will get shorter, and the risks of running into problems will be greatly reduced.
How the inside radius forms
Press brake guru Steve Benson describes how the method of bending—coining, bottom bending, or air forming—is very influential on how an inside bend radius is achieved.
