Pyramidal bending machine, 3 driving rolls with adjustable center-distance.
The top roll is hydraulically adjustable whereas the lower rolls are adjustable in three different positions.
The adjustable center-distance is very important for the profile bending with different shapes and structures.
For example, the wide position is suitable for the bending of rectangular and square tubular profiles or special profiles for window frames with close section. The wide center-distance position allows using a fairly wide bending radius by making the bending easier and avoiding the collapse.
The narrow position is suitable for slim and asymmetric profiles. In this case, the deformation is better held in and makes the material feeding easier in every condition thanks to the specific pressure of the bending roll to the material.
The middle center-distance are more used for the round tube bending because it is possible to obtain very small radii without ovalization.
The geometry of this machine allows bending a wide range of profiles, especially in window frames but also in carpentry and in many other productions.
Since 2009 we have a new DELTA 50 version: DELTA 50 PLUS with CNCì
