Finding the optimal device:
The AKAS safety systems of Fiessler Elektronik are in daily industrial use in more than 35,000 press brakes. Fiessler Elektronik safety solutions for press brakes consist of an optical safety device and a safety control. The components are CE type tested, (c)UL listed, DIN EN12622, B11.3, NR12 and comply with many more national and international standards.
Operating principle of optical protective device:
Designed for OEMs, the New AKAS-3P Optical Laser Light Guard as a three-dimensional laser protective field between the AKAS® transmitter and AKAS® receiver monitors the hazardous area underneath the clamped upper tool. The AKAS-3P has a fast speed up to the claming point, where as the AKAS-3 has a fast speed up to 5mm. The special type of beam configuration guarantees protection directly up to hazardous area. Depending on the machine performance (stopping distance of the blanking press), the press can be operated at high speed. Shortly before the upper tool touches the sheet metal to be bent.
The AKAS press brake safety system is offered in various versions and can therefore be optimally adapted to the respective situation. Safe area: Protected zone (any intervention into this area shuts down the closing movement of the press).
Exactly right for every bending type
Flat bending mode
Box bending mode
Bending of wavy material
AKAS®fully automatic adjustment
AKAS®with fully automatic motor adjustment:
To optically broaden the tip of the top tool, a magnetic lamina is fastened to the upper tool.
When the automatic switch is pressed, the transmitter moves to the optimal monitoring position.
The receiver follows this movement.
Fast speed approach to clamping point, OEM preferred
AKAS-3PM/PF – M No gate inputs, can use existing encoders, M/P used by OEMs, P used only with
Fast speed approach up to 5mm, considered for retrofit
AKAS-3M/F – 3 laser beams, M No gate inputs, can use existing encoders or maybe retrofittable if
control provides speed change signal.
Fast speed approach up to 10mm, retrofittable
AKAS-2F — Most versatile retrofit style, mini safety PLC, magnetic encoders, 2 speed movement, relay
driven, brake overshoot 14mm max.
2F/LC – Most preferred 2 beam retrofit models, LC is manually adjusted to maintain parallel to the punch.
AKAS-2F is the automated version providing that function by pushing a button.
