Flanging
The forming of endless flanges on the sheet, even on bent edges.
Flanges
Flanging can be applied in the simplest way even on the edge of a bent sheet. The tool folds the sheet locally upwards to a desired height H, it is displaced a little further and the process repeated, in a similar way to nibbling. The quality of the flanging depends on the feed speed, therefore it is recommended to note the feed speed on the production drawing to obtain a high-quality flange.
Flanging is used both to reinforce the edges of the sheet and for a welding collar (bottom image) or countersinking. It is also frequently used to produce larger extrusions.
Notes on manufacturing
- The thickness of the sheet S can take values between 1 mm and 2.5 mm.
- The maximum forming height H of the flange is 7 mm.
- The relative angle between the plane of the sheet and the bend is 80° in all cases.
- The radii of the contour RK must be at least 30 mm for the outer edges with downwards forming and 80 mm for upwards forming. For the inner edges, a minimum contour radius RK of 80 mm is envisaged, when the forming is carried out downwards, and when forming upwards, it is 30 mm.
