1.2. PRINCIPLE
The machine is a manual loading/unloading hydraulic press brake.
HF-type hydraulic press brakes are down-stroking machines equipped with a numerical
control ensuring the control and adjustment of all bending parameters.
These press brakes are equipped with a central reaction Lower Beam to ensure bending
quality.
An electrohydraulic servosystem controls the travel and ensures that the Upper Beam (UB)
remains perfectly parallel to the Lower Beam (LB).
These machines can be equipped with various options (back gauge, front gauge, etc.), with all
Amada tools, and other traditional tools, as well as a range of various accessories. (Contact
our Local Sales Representative to discuss your specific requirements.)
For items heavier than 25 kg, a handling device – not included in
Amada supply - must be provided to the operator.
REVIEW OF THE CONVENTIONAL DESIGN OF PRESS BRAKES
Due to the reactions of the part under the thrust of the cylinders located at both ends,
traditional down-stroking press brakes experience an elastic deflection during bending
in opposite directions on each beam.
These deflections can be detected by a difference in terms of punch penetration in the
die, slightly minor in the center than at the ends (Fig. 1.2).
