Brake pressing is the most widespread method for bending of metal sheets, and a bending-off press has many applications.
In its mechanical design, a bending-off press (bending machine) is very simple:
Under great pressure, a so-called upper die, often shaped like a wedge, is moved against a lower die shaped like a V. The sheet is placed between the tools, and the sheet is bent between the tools. Modern bending-off presses are CNC-controlled so both workpiece position and tool position can be controlled very precisely. In addition to achieving precision and uniformity, the workpieces can often be completed in one operation cycle even if there are many different bends on the workpiece.
Bending-off pressing is the most flexible, accurate and economical method for bending of sheet workpieces in small and medium-sized series and the only method for bending of large workpieces. Bending-off presses are available with pressures from a few tons to over 1000 tons and with the option of bending lengths from 0,5 m to 24 m or more.
GBI (Gl. Bedsted industri A/S) bends lengths up to 4 m with a pressure of 160 tonnes (1600 kN) and with 8 CNC controlled axes. The combination of CNC-control, 8 axes and many tools allows us to bend all material thicknesses up to 12 mm.
We also offer bends in special shapes (e.g. radii, trapez) where we manufacture bending tools ourselves for the specific assignment at competitive prices. Back
