Press Brakes
Amada: www.amada.com/america/press-brakes
Equipped with a patented automatic tool changer, Amada’s new HG 2204 ATC press brake ensures quick and precise auto- mated tool changes. The auto- mated setup and repeatable accuracy achieved by the HG ATC enables fabricators
to introduce rush jobs seamlessly.
Designed to handle variable lot sizes and complex tool
layouts, the automatic tool changer loads new tools within 3 min. And, the HG's 13-ft. bed facilitates multistage bending operations and supports bend lengths to 161.4 in.
Other standard features include an integrated bend sensor that guarantees consistent bend-angle accuracy.

On average, machines in the latest Prima Power eP-series servo-electric press brakes consume 50 percent less power than hydraulic press brakes, say company officials. The brakes also require less maintenance, (Prima Power calls this Green Means). The press brakes employ a pulley-belt system designed to distribute the applied bending force
over the entire bending length, while a rigid
and stable
O-frame
ensures
optimum
tool align-
ment. Ram-
position
accuracy
and repeatability are bol-
stered by bed-referenced linear encoders that
measure the relative positions of the upper and lower beams.
Press brakes in the eP series have no throat limitations, enabling bending of long parts. There are four models in the lineup—the eP-0520 (550-kN bending force, 2020-mm bend length), eP-1030 (1050 kN, 3060 mm)), eP-1336 (1350 kN, 3655 mm) and newest model, the eP-2040 (2000 kN, 4080 mm).
Trumpf: www.us.trumpf.com
High axis speeds and acceleration rates, combined with
innovative operating aids, lead to unparalleled productivity with Trumpf’s new TruBend Series 5000 press brakes, in four models from 500- to 1700-kN bending force and 1275- to 3230-mm bending length. Each features a new on-demand servo drive with four-cylinder drive technology.
To ensure bend-angle precision, the brakes provide two innovative angle-measuring systems: automatically con- trolled bending (ACB) collects measurements through sensors integrated into the upper tool
and the ACB Laser system measures bend angle
using a con-
tactless
optical
process. Use
the ACB setup
for bending short
sides, reflective
surfaces, or when
multipoint measurement is
required, and use the ACB Laser system
when processing acute and open angles, as well as for bend- ing thick material.
The entire bending process is facilitated by the Touchpoint TruBend control concept—an intuitive interface that features realistic 3D visualization and a multi-touch screen. And, a tool indicator features LED lights that help to reduce setup times by precisely displaying bending-tool location.

LVD Strippit introduces a range of press brakes to its bending-product line, the PPED series of hydraulic brakes that feature a CNC crowning system and a 15-in. version of its Touch-B CNC controller. With minimal input, an operator can create designs in 2D and simulate in 3D. The machines come in three models, with bend force from 50 to 320 metric tons and bend lengths from 78 to 157 in. The largest model, the PPED-7, is equipped with a standard crowning system— sheet thickness, bend length, punch radius, die opening and material data are entered into the control to determine
the amount of crowning required. Also new: Syn- chro-Form adaptive bending technology, which automatical- ly maintains angular consis- tency and the required geo- metric profile when bending large parts with multiple bends. A laser scanner sends measurement data to the Touch-B control, which then directs the required adjustments to part and ram position, compensating as needed with each bend strep. Synchro-Form is integrated into the firm’s Synchro-
Form series of press brakes.
