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.

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.

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.

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.

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.

Freeing a bending bottleneck can backfire if it simply creates a severe bottleneck downstream. Bending throughput may increase, but overall throughput--the metric that really matters--may not. That’s why the best bending automation considers not only the bending department but also the throughput of the entire plant.

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.

Changing the die opening can dramatically change results during air forming. In precision sheet metal fabrication, choosing the correct die opening should not be a guessing game.

Iowa-based Co-Line Welding hasn't let its remote location harm its chances of success. In fact, it has embraced the challenge and has emerged as a growing business, even as it faces challenges such as rural power distribution.

Advanced controls make a highly variable process more predictable Abstract: Experience still is important when it comes to plate rolling. But the more knowledge industry has gained about the materials being rolled, the more “intelligent” plate roll systems have become.

When a fabricating operation serves customers in the defense, heavy equipment, mining, and power generation industries, you know they are working with really thick and high- strength material. It's a big job and requires big equipment. It's also the main reason that Merrill Fabricators purchased a 2,000-ton, 38-foot press brake.
