Pairing a servo feed with a pull-through straightener

December 13, 2001

By:

This article explores the possibility that servo feeds can be used with pull-through straighteners as opposed to a conventional feed line that uses a powered straightener. Using the servo-PTS (pull-through straightener) can save money on equipment and material. The only limitation may be marking the material so noncosmetic applications are recommended.

Designing presses and dies with FEA

November 29, 2001

By: ,

To develop or find a new tool and perhaps a new press to make a part, managers need information about the tonnage requirement, which mean they will need to know more about how the part will form and the loads it will impart into the press and tooling also. Linear or nonlinear finite element analysis (FEA) can find the information so managers can make an informed decision. With FEA, a fabricator uses a computer-aided design system to develop a model of the part, and then the computer divides the part into many small parts. The FEA software then applies standard stress analysis equations to each side of every part.
