INNOVATIVE CONTRUCTION PHILOSOPHY IN BENDING MACHINE

In a globalised world it may seem trivial to underline the origin of a product, but nowadays it’s important to assure clientele that entire production is all studied, designed and assembled in Italy. Especially in these times of worldwide crisis in industry it is important to point out that the company has continued to develop, refurbishing with a new high quality management system, SAP, worldwide leader in software solutions for business. Furthermore, a lot of energy has been spent in finding new technical solutions in the manufacture of the machines, in testing new products for special processing and in continual updating of the CNC-i numeric control–core and real added value of all bending machines.

LAMIERA 2010 exhibits a synthetic but significant series of high quality products manufactured by the company that has been UNI ISO 9001 certified for many years. The construction principle applied by most manufacturers consists in two angle rolls, mounted on pivoted levers on a central pin, that follow an orbital path, a third fixed roll overlays these two rolls, in a central position in relation to the other two.

CNC bending machines geometry is very common because production costs are less. However, this system has certain equally evident drawbacks, due to the forces involved, that subject the structure to considerable stress concentrated in a single point: the central pin. This is the weak point of the entire system, because, even if largely over-dimensioned , it will never have the necessary stiffness to ensure an even distribution of the stress it is submitted to.

The company has built and patented an innovative drive and support system of the roll-carrier shafts on slides with a linear stroke, which is much more precise and stiff than the system previously described. To this important development the possibility is added to be able to apply independent supports, that restrain the ends of the shafts greatly restricting deflection. The slides with their straight-line stroke act as the base to assemble the supports, so that also during adjustment of the slides, the shafts are always rigidly restrained on three points.

Possibility to bend section bars with a double pipe bending strength, compared to a bending machine with conventional drive system at the same cost.

The possibility to have an immediate saving on the purchase of a bending machine, which is much smaller, but appropriately dimensioned for the steel bending needs required.

Considerable saving on cost and on the handling of fixtures, much less cumbersome and with higher dynamics in the operations.
