Hybrid and Servo Press Brakes

KAAST has added a wide selection of hybrid and servo brakes to its CNC press brake line up. They range from 3' to 20' in length and feature tonnage options ranging from 40 tons to 2,000 tons.

The HPB-E servo/electric brakes feature a CNC controlled 4 axes (X, R, Z1, Z2) backgauge system run exclusively by AC servo motor. "Crowning is no longer necessary due to the consistent pressure across the beam," said a company spokesperson. "The beam downward movement is performed with the aid of belts, and its return is performed with springs, producing only 63 dB of sound level and making these the quietest among the sheet metal bending machines."

The HPB-H hybrid brakes feature a CNC controlled 4 axes (X, R, Z1, Z2) backgauge system that is run by an AC servo motor paired with an efficient, minimum maintenance, closed-loop HOERBIGER hydraulic system. "This combines the accuracy of an electric press brake with the power of a hydraulic system. The included CNC controlled motorized crowning system saves time and material," said the spokesperson.

The HPB-E and HPB-H offer quick set-ups and consistent bend angles, especially for air forming-the bending method preferred for these machines. With the precise linear bearings and the sliding front support arms that move right and left on the rail, the sheet can easily be controlled by the operator from the front. Also, the length of the parts can be measured by means of the ruler mounted on the front support arms. The sheet can be fixed from the front side with the aid of the flip stop that is mounted inside the T slot.

The machines begin with a steel body monobloc welded of ST44 material, which is rigid against twisting. These brakes come standard with 6 axes (Y1, Y2, X, R, Z1, Z2) with a CNC controlled backgauge system with 4 axes (X, R, Z1, Z2). Top and bottom tools are hardened and ground (835 mm length) and offer an easy clamping top toolholder system. The DELEM 66T CNC controller is run on a 3D color graphics display and offers offline software as well as programming at the machine. The electric panel and its cooling system are designed and manufactured by Siemens electrical and automation products in compliance with CE regulations.

The HPB-E and HPB-H feature the new generation DA-Touch controls offering a higher grade of efficiency in programming, operation and control of today's press brakes. Ease of use combined with state-of-the-art technology improve productivity. The touchscreen gives access to the Delem user interface and enables direct navigation between programming and production. Functions are directly located where they are needed for optimized ergonomics. The DA-66T offers 2D programming that includes automatic bend sequence calculation and collision detection. Full 3D machine set-up with multiple tool stations gives feedback on product feasibility and handling. Effective control algorithms optimize the machine cycle and minimize set-up time.
