Profile bending is a metalworking process that involves bending metal(steel or aluminum) profiles (such as beams, tubes, and bars) to form specific shapes or curves. The following are the steps typically involved in the profile bending process:
Six steps of the profile bending process
- Steps 1#: Loading bending metal profiles – the metal profile is inserted in between the top roller and the right lower roller. The metal profile can be supported if necessary and is not subject to deformation stress.
- Steps 2#: The right lower roller up to the top roller movement achieves the pinching position – the metal profile is blocked in between the rolls and can be moved forward and backward rotating the rolls. The pressure exercised is lower than the one necessary to deform the profile.
- Steps 3#: Pre-bending between the top roller and the left roller – the right roller slowly rises, starts rolling, and performs pre-bending between the top roller and the left roller.
- Steps 4#: Working phase – in this phase the pressure increases and the deformation of the profile takes place, by translation of the profile and movement of the rolls.
- Steps 5#: Pre-bending between the top roller and the right roller – The left roller is down and the right roller is raised. The material is sent to the left and the three rolls begin rolling, pre-bending between the top roller and the right roller.
- Steps 6#: Unloading of the metal profile – the pressure on the profile is eliminated and is increased the space between the rollers so that the profile can be extracted from the machine.
It is clear that, in order to load the profile on the angle roll machine, a sufficient distance between the rollers must be present. It is also clear that, in order to block the profile in between the rolls and to apply pressure, it is necessary that this distance is reduced. Une or more rollers must be capable to move with respect to the others.
