Roll form tooling design for air bending: Selecting a techique for reduced distortionSeveral techniques are used commonly to reduce profile distortion when air bending with a roll former. These include small-radius forming, false bending, vertical side rolls, and angle side rolls.

Pumping up productivity on older press brakes: Increasing productivity with advanced tooling, clamping, crowning systemsYou may be able to improve press brake productivity and eliminate bottlenecks with more advanced tooling, anti-deflection [crowning] systems, and clamping systems. Such advancements have made it possible to form a larger range of materials and part configurations with fewer tools than before.

Bend allowance and springback in air bending: How to predict it and compensate for itThis study illustrated that, when the thickness and stress-strain curve of the sheet material are known, it is possible to predict with acceptable accuracy the bend allowance, springback angle, and punch stroke to obtain the desired final product dimensions.

The evolution of precision bending: Bending moves further from art, closer to scienceThree decades ago bottoming with penetration, or coining, was the only way to achieve high accuracies on press brakes, and this meant fabricators endured high tooling costs. Over the years precision air bending with CNC hydraulic press brakes using precision-ground tooling evolved to become the dominant forming method in the precision market. However, it took some significant machinery advances to get there.

Bending with kid gloves: Urethane press brake tooling leaves no scratch behindPolyurethane film, inserts, pads, and bottom dies can help prevent marring and, in some cases, allow the die to take on a variety of materials and gauges, including perforated metal and diamond tread plate.
