New bending machine: advantages

Versatility of bending machine, that can bend large size profiles, as well as profiles with small dimensions and radii, with its combination of considerable useful length and elevated stiffness of the supported shafts with a centre distance between the bending rolls having a wide variability range due to the converging straight-line guides.

Longer machine life because of the optimal distribution of the forces. Hydraulic pipe bender adjustment of the bending axes speed makes it possible to position the rolls with maximum precision. For example, during multi-pass bending, it is possible to rapidly approach the required radius and the subsequently finish the bending with maximum precision finely adjusting the position of the bending rolls. A longer life of the machine because of the optimal distribution of the forces.

The excellent geometry of the Alpha series, permits, with the same performance as a bending machine of the competition, considerable energy saving (on average the power required is halved).

Square tube bending has an innovative multi-axis positioner that permits a completely independent handling of the moving parts of the bending machine where it is applied.

The operator interface is incorporated in a panel of appropriate dimensions, that encloses in a single instrument all that is necessary to ergonomically manage the bending machine, avoiding confusing and bewildering indications caused by many devices spread out over the machine. The PQ10 is the latest electronic interface, designed specifically to meet the management requirements of pipe bending machines with more than 3 separate axes. With the touch-screen display and the Microsoft Window. CE operating system the use of the multiple PQ10 applications are intuitive and fast .

single axis positioning, setting the required dimension on the main screen and activating the actuator of the axis.

sequential multi-positioning of axes, used to carry out the movement of several axes continually and in sequence up to the required dimensions.

It is possible to set up to a maximum of 10 dimensions for each axis; the control electronics permit positioning of the bending axes with a precision of 0.1mm, whereas for auxiliary axes the precision is 1mm.

Possibility, at any time, to rotate the machine synoptic panel by 180°, to adjust the screen to the requirements of the operator.

The PQ10 also includes an advanced analysis system for self-diagnosis of any failures and/or maintenance operations on the control circuit. When necessary a warning is displayed with a description of the failure and a photo of the area requiring attention.

Upon request the metal bending machines can be supplied with a tele-assistance system for prompt service in any part of the world.

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.
