Bending

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.

Up Around the Bend

April 11, 2005

By:

Red Dot Corp., forced by eroding margins to consider lean manufacturing and reduce lead times, embarked on a project to reduce wasted time, materials, and space. As part of this project, the company decided to move some of its manufacturing processes from its main plant in Seattle, Wash., to one of its distribution hubs in Ipswich, England. Because the facility would rely on a single press brake, Red Dot shopped around for a press brake that would run continuously with a minimum of service calls. The company's success in press brake operations in Ipswich led it to overhaul its press brake operations in its facilities in Seattle and Memphis, Tenn.

Air forming and V-die selection

May 4, 2004

By:

Air forming, bottom bending, and coining are metal forming methods. Air forming, the most common, is a three-point operation. The actual inside radius produced is based on a percentage of the V-die width, regardless of the sharp–radius relationship. Selecting the correct die width can be...

New bends in the roll

April 6, 2004

By:

As more commercial buildings are designed with larger open spaces, the beam spans grow longer, and the beams must be bigger and heavier. This requires ever-larger section bending rolls to accommodate this demand. In addition, the trend toward the use of higher strength steels has taxed the capabilities of plate roll bending equipment. These changes and other emerging demands have driven the trend toward the use of CNCs, inline material handling, and larger angle bending rolls.

Why should you care about inside bend radii?

January 29, 2004

By:

Operators, designers, and engineers, why should you care about the inside bend radius if the customer doesn't? Because, ultimately, just how easy or difficult it is to produce a part depends on decisions made during the design stage. Misunderstanding terminology, process capabilities, or production methods can lead to mistakes that can make production more difficult. The most common mistake is incorrectly calculating and achieving the correct minimum inside bend radius.
