A balanced combination of powerful electric servo motors, fixed and moving pulleys and specially developed belts make it possible for the SAFAN’s E-Brake to handle over 200t. It is available from Sheetmetal Machinery Australia .
The unique patented pulley drive in the E-Brake’s top beam produces a very even and immediate distribution of forces, allowing for the most accurate and constant bending angle along the full range of the machine, without the need for crowning.
The E-Brake requires less critical parts, no hydraulic oil – therefore there is no leakage or heating up of the machine frame.
The E-Brake also allows for optimal safety with integrated lightguards, quicker response time of servo drives, resulting in increased cycle times.
SAFAN's servo-electronic technology has been successful throughout the world since 1995. The SAFAN E-Brake concept constitutes a further improvement on this technology, one that is resulting in ground-breaking performances.
The new E-Brake has shorter cycle times, more advantageous use of energy and substantially lower costs for maintenance in comparison with traditional hydraulic press brakes.
SAFAN has effectively adapted the technology and construction to the E-Brake’s area involving weights up to 200t and work lengths up to 4m. A strong point of the construction is the level foundation.
The SAFAN E-Brake 150-3100 and the SAFAN E-Brake 200-4100 are both equipped with a heavy-duty sized CNC-controlled backgauge system that is equipped with two ball screws and play free ballscrew linear guides. The E-Brake concept offers a unique advantage: the backgauge can be used over the entire working length of the machine.
The standard backgauge is equipped with a CNC controlled X axis and two backgauge fingers that can be manually moved along the bending line (Z axes) as well as adjusted in height (R axis). The fingers are provided with interchangeable stops.
The backgauge system can be optionally fitted with CNC controlled R and Z axes and a dX axis. It is also possible to fit a fully 3D backgauge with X1, X2, Z1, Z2, R1 and R2 axes.
Electronic operation and control of the E-Brake is via a Touch Screen. The SAFAN TS1 control is the most user friendly and effective man/machine interface available. The control is PC based and uses Microsoft Windows.
An intelligent feature of the SAFAN TS control is that it only displays those buttons that are required at the particular stage of operation.
The adjustable height of the control unit ensures optimum ergonomics for any operator, whether short or tall.
A standard accessory is a 100MB Ethernet UTP network connection that opens up unlimited possibilities.
The instructions from the SAFAN TS control are sent to a central processor, which in turn activates the various axes by means of a CAN-BUS (Control Area Network). The advantage of this system is the electronics are of a modular construction, requiring fewer components. This means a high degree of flexibility and compatibility, as well as great reliability.
