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.

Customers want parts right away, and newer laser cutting technology is producing parts quicker than ever before. If a fabricator wants the bending department to keep up, it needs press brakes that can bend parts quickly. Even with the increased bending productivity, however, fabricators don’t have to sacrifice safety.

Bending small parts presents various challenges for press brake technicians, who need to make sure they can bend these small parts quickly and, most importantly, safely. Although the best approach to bending depends on the application, the electric press brake can help make the job much easier.
Some metal fabricating shops rely on press brakes and bump forming to make cylindrical shapes, while others are more adept at using plate rolling machines. This feature explores the factors involved in determining whether a press brake or a plate roller is the right machine for the job.

For many, ideas such as green and sustainability are synonymous with recycling, but recycling is just one small part of doing things in a greener way. Minimizing the consumption that later needs to be recycled (waste) is an important aspect, too. Among tube and pipe fabricators, one area that can yield big benefits is lubricant consumption.

Properly setting up the tooling on a tube or pipe bender can be a straightforward process, but misunderstandings and shortcuts can lead to poor setups. The wiper die’s rake angle is one such setting. Operators should beware that setting the tool to a specific gap at its trailing edge can lead to inconsistent setups.

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.

BEPeterson, Avon, Mass., used to be a weld shop. Most of the work was seasonal, which isn’t really a solid foundation for growth. The fabricator changed that with a commitment to diversification. Today the company has three unique business units: power utility, medical, and pressure vessels.

Bending plate is not a process that metal fabricators consider to be a highly efficient one. The blanks typically are large and awkward to handle. Fortunately, the proper tooling strategies can help.

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.

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.

Robbins Manufacturing of Fall River, Wis., has invested in an extensive training program, including machine-specific training, especially on the press brake. The company also has invested heavily in new technology, including a brake with automatic tool change. Both investments are paying off.

The automatic backgauge, which began to permeate shop floors in the 1970s, really was a revolutionary step forward. In fact, without this step forward, sheet metal fabrication wouldn’t be the business it is today.
