The wiper die’s role and rake

April 3, 2014

By:

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.

Bending basics: Why profound-radius bending is a different animal

January 27, 2014

By:

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.
