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.

Shop floors are filled with advanced technology, and this includes the press brake department. As bending guru Steve Benson explains, you still need skilled technicians to make the best use of that technology.

Plate rolling is not as simple as using a press brake to make a 90-degree bend on a small piece of metal. With the right equipment, however, a fabricator can learn to become a very good plate roller in a short amount of time.

Bending large sheet metal parts does not represent the majority of work for most metal fabricators, but it can be a significant portion for those shops that have the capability to do it. These equipment considerations and processing tips can help make a big bending job easier to accomplish.

In the early 2000s, Innovated Machine & Tool Co., Newport News, Va., tried a robotic press brake for a bending job and found that it worked out well--for that job. Unfortunately, when the contract ended, so did the useful life of that robotic press brake. Since then, the shop hasn't had to worry about machine obsolescence because its panel bending technology is helping it stay on top of all sorts of bending work.

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.
Any fabricator that has had to wrestle with large panels or thick plate in a press brake has to wonder if something can be done to make the job easier. In many instances, specialized tooling can help.

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.

Over the past few years, North Shore Steel has transformed its plate processing division into a provider of highly engineered, precision-cut and rolled components.

Alto-Shaam, Menomonee Falls, Wis., needed to find a way to reduce setup times for its low-volume, high-mix work associated with fabricating parts for food service equipment. The company found its answer with a panel bender that management had seen in action at a FABTECH tradeshow several years before.

A high-product-mix manufacturer chooses robotized bending not because it lacked a skilled workforce, but because it wanted to make the best use of the talented workforce it already had.

Press brake manufacturers have responded to industry’s need to produce small batches of parts that require frequent tooling changes by designing options and systems to reduce setup time by managing, storing, and automatically changing upper and lower tools. Operators can spend less time physically involved with setup and more time with the profit-making bending process. Reduced margin for error and less scrap are added benefits. However, there are steps that can be taken to reduce setup time without investing in new press brake equipment.

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.

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.

Why calculate values such as bend allowance, outside setback, and bend deductions? Because sometimes you will need to work your way around a bend on a print, and you may not have all the information you need to complete a flat pattern.

The FABRICATOR talks with Jeff Visser, production managers at Avon, Mass.-based BEPeterson, about the basics of plate rolling operation. Plate rolling is part art, part science. It requires skill, and not just anyone can do the job right.
