The Pressbrake safety System AKAS meets the safety requirements of category 4 according to EN 954 and
prEN 61496, and the most recent requirements of prEN 12622.

Innovative finger guarding system for pressbrakes by following LASER optical safety light grids in front of the tool.
Finger guard works during the foot pedal controlled bending process => hands remain free for the operation with the slug.
Increase of productivity due to programmable adaptation of the AKAS® II to the individual overrun traverses of the machine.
Short change-over times due to all-automatic change-over to other tool sizes.

Problem

The characteristic feature of press brakes is the performing of the movement of a tool, usually the upper tool or the bending punch, that moves towards a fixed tool, (the matrix or the bottom platen of the press) , consequently bending the metal sheet placed between them. When manufacturing small components, lot jobs or special single-piece production, the machine operator must hold and adjust the small pieces by hand during the bending process. Hands and fingers are endangered when doing so.

Problem Solving

The following LASER-optical safety light grid AKAS® prevents the trapping of a part of the body between the bending punch and the inserted sheet metal, i.e. the matrix.

Description of Function

The Press brake Laser guarding System AKAS®-II is is a special protective device for press brakes.
It consists of transmitter, receiver and LSUW N1 MUTING K controller (switching unit) or the Safety PLC FPSC.

The AKAS®-II transmitter gereates two modulated visible red laser beams.

The AKAS®-II receiver consists of three detecting elements and of one evaluation unit.

Transmitter and receiver are fixed to the ram of the machine and form a Laser-optical safety light grid which is
located in front of the bending punch.

With the Laser-optical safety light grid AKAS®-II the hands remain free for handling the slug during the
operation under continuous protection of the extremities during the whole bending process.

Electromotor driven actuators located in the AKAS®-II supports provide a quick and easy, all-automatic adjustment of both AKAS®-II transmitter and AKAS®-II receiver according to the requirements of other tool sizes.

technical data

In dependence on the maximum overrun traverse of the press brake, the AKAS®-II can be programmed in a
way that its productivity output is optimized by eitther a maximized fast speed traverse, or a minimized slow
speed traverse can be achieved. The value X can be fed into the system during the initial installation of the
AKAS®-II according to the overrun traverse of the press brake. A short overrun traverse will require a smaller
value for X, therefore the press can be operated longer in fast speed, thus saving time.
