UniBend E 2550-80

Main features

Rigid О-frame machine bed

Robust O-frame bed construction ensures equal load distribution on the side frames thus removing the horizontal deflection and ensuring precise and predictable operations.

Unlike C-frame machines the side frames do not limit complicated details and back gauge allows for movements along the length.

We use self-engineered servo drives and drive systems

Servo drives for servomotors Unidrive series ensure the highest precision and easiest movement maintaining the maximum dynamics. Application of specially designed proprietary technologies to control servomotors results in precision and efficient operations with minimal offset within all speed and acceleration ranges.

Motion controllers UniMotion produced by Unimach® ensure mutual synchronization of servo drives. High speed ensures absence of tilting and unparalleled precision. Positioning accuracy of upper beam is ±0.01mm.

Belt drive

Controlled by servo drives, belt drive allows for uniform distribution of bending force along the upper beam thus providing minimal errors of bend angle along the whole workpiece.

Automatic back gauge system

Depending on the volume and tasks of the manufacturing, automatic back gauge can have from 2 to 9 CNC-controlled axes thus ensuring the required level of equipment automation.

During operation life the press brake can be modernized by increasing a number of back gauge stops and adding CNC-controlled axes. Since the back gauge system is located on the separate frame any mechanical damage of the frame with bending tools is excluded.

Tooling system

Press brake UniBend is equipped with international well-known tooling system Amada-Promecam. Clamping of punches is carried out with the help of keybar adaptors enabling to align the tools in a perfectly straight row. Different types of adaptors ensure dies clamping.

High ergonomics

High ergonomics ensure low level of noise, convenient layout of control elements and both simple operation and maintenance. Safety components and guards protect an operator while both operation of the machine and its service.

Mounting system of control console allows for adjusting the workplace according to the workpiece positon on the lower beam. Using a tablet as a control module an operator can work in close proximity to the bending zone.

Control console

Press brake is controlled by the dust-proof control console equipped with a 15.6” touch panel. The console is mounted onto the frame with the help of rotating brackets enabling an operator to adjust it along the bending line and upwards for the most convenient position.

Touch panel ensures an easy integration of UniBend software into the production, significantly simplifying workpieces’ plotting as well as creating and editing bending programs.

Tablet

Additional control element – the tablet with UniBend software – has a magnet mounting which makes it possible to place the tablet anywhere on the upper beam.

It also ensures full control over machine operations in close proximity and visual monitoring of program and software commands execution.

UniBend software

Developed by Unimach specialists our software has a user-friendly interface and operations control made-easy. Wide functionality allows for automatization of different press brake operations – from creating a bending program to machine adjustment under the workpiece size.

Sensor control makes an operator’s work even simpler and increases production efficiency. Menu icons correspond to every operation stage, their sequence repeats operator's actions allowing for easy and convenient use of software product.

Bending force is calculated automatically depending on the workpiece’s size and material. When the workpiece processing requires a sequence of several bends, the program automatically sets it up. An operator can correct it if necessary.
