Area of application
- 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.
- Press brake guarding
- Shears with pressure pad
- Blanking presses
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.
Safety integrity level SIL 3 (IEC 61508)
Performance Level PL e (ISO 13849-1)
Safety category Kat 4 (EN 954-1)
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.
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.
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.
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 either 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.
Standard travel distance of support: 150 - 200 mm; special travel distance on demand.
