Basic Magnet Design
The Magnabend machine is designed as a powerful DC magnet with limited duty cycle.
The machine consists of 3 basic parts:

The magnet body which forms the base of the machine and contains the electro-magnet coil.
The clamp bar which provides a path for magnetic flux between the poles of the magnet base, and thereby clamps the sheetmetal workpiece.
The bending beam which is pivoted to the front edge of the magnet body and provides a means for applying bending force to the workpiece.
Magnet-Body Configurations

Various configurations are possible for the magnet body.
Here are 2 that have both been used for Magnabend machines:

The dashed red lines in the drawings above represent the magnetic flux paths.
The dashed red lines in the drawings above represent the magnetic flux paths. Note that the “U-Type”
design has a single flux pathway (1 pair of poles) whereas the “E-Type” design has 2 flux pathways (2 pairs of poles)
