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.

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.

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.

Robotic press brakes may offer higher productivity and better profitability--much of which is achieved by running the press brake lights-out at top speed. In some cases, robotic press brakes can reduce per-piece costs by almost half. Still, robotic press brakes aren’t for every application.

Ben endured the same frustrations many press brake department supervisors face. Operators get a print that doesn’t take the proper bend deductions into account. They fudge it, performing test bend after test bend. Productivity suffers, and the bottleneck ensues. At Ben’s shop, this all was about to change.

CAM software have made it easier and more affordable for job shops to increase efficiency and productivity without sacrificing quality. Staged bending combined with offline programming offers strategies for reducing downtime, improving part flow, and controlling costs.

Kysor/Warren, Columbus, Ga., cutomizes the refrigerated display cases and refrigeration systems for its customers. Unfortunately, it didn't have a very efficient bending operation to keep up with the production demands related to its diverse product line. To remedy the situation, the company purchased Wila precision ground tooling and installed hydraulic clamping systems on its press brakes.

Within electric brakes, bending force is distributed differently. Also optoelectronic safeguards integrate closely with the control, so much so that a light curtain or similar device has no effect on the bending cycle time. In fact, in the electric press brake arena, safety does not necessarily require a sacrifice in cycle time.

An electric press brake is not typically found in a metal fabricating operation, but that is changing as more companies realize the accuracy, speed, and energy savings that this type of device offers.

Shop rolls beams for a unique place of worship--using an unusual process Abstract: Hardwick Co., a rolling shop in Birmingham, Ala., used its unusual induction beam rolling process to form beams into complex shapes involving multiple radii. Without such capability, the impressive design of the Ave Maria Oratory would not have been possible.

These days, plate rolls are forming plate 6 and 7 inches thick--and even thicker. Vessel designs that would have been forged just a decade ago are now being sent to fabrication houses. The variable-geometry plate roll system, which really operates more like a press brake than a traditional plate roll, is making such extreme rolling possible.

Tread plate and perforated sheet present significant bending challenges. To help matters, fabricators may need to look beyond typical air bending with a punch and V die. Though bending alternatives vary, they have one commonality: They clamp down to ensure the workpiece stays where it should.
