Home > Safety Device > Protective Equipment for Press-Brakes [AKAS] AKAS is the most well known safety equipment widely used in Europe for press-brakes.This equipment will prevent the danger of press-braking work without reducing the worker productivity. Generally, press-braking work in the past incorporated two-optical-axes shielded ray-type safety equipment as a safety measure. However, when you do special work in which you cannot use such safety equipment (work such as processing a small piece of material by holding it with your fingers), you have to neutralize the safety equipment. This AKAS conforms to the European Safety Standards (EN954 Category 4) and is suitable for application to the International Standards (IEC61496-1, 2 Type 4). It can secure safety and productivity without neutralizing the safety equipment. 1.  Pinpoint monitoring by the laser sensor. 2.  Safety monitoring can be done even when you hold a work piece with your fingers during the stroke of the ram. 3.  When exchanging a tool, you can easily perform any adjustment required. 4.  Monitoring in compliance with the needs of the work. (Effective positions and ineffective positions will be automatically set in accordance with the stroke.) Three calibrated laser beams from the projector are received by four beam receiver units, and the presence of laser beams will be detected to determine whether they are cut-off or not. Then the seizing signal of the press-brake will be cut off. All laser beams are treated as effective beams up to the low-speed change-over point (the bottom dead point, 23mm above the work piece) and then the beams will be neutralized in sequence. All the optical axes will be neutralized and suspended at a punch mark 8mm to 9mm above the work piece. * This function is available only on a machine having a changeover position to low-speed that is adjustable and the speed of the low-speed action is less than 10mm/sec. Movements and adjustment of the projector can be easily done by changing the tools. Adjustment of the beam receivers can be automatically done by using a single control knob. Type Description AK/160/SE A product set with a support which allows the AKAS projector and receivers to move 160mm. AK/200/SE A product set with a support which allows the AKAS projector and receivers to move 200mm. AK/300/SE A product set with a support which allows the AKAS projector and receivers to move 300mm. AKAS/AS/1 1 AKAS Clamp AKAS/AS/2 2 AKAS Clamps AMS Muting system with magnetic scale positioning sensors. System Configuration Projector and Receivers Muting Control Unit (LSUW N1 Muting) Operating Voltage 200V 50/60 Hz -10%, +10% (DC24V, 100V are optional) Response Time 25ms (from the protective cut-off to the on of the output contact point) In the case of the AKAS with the Muting Control Unit (LSUW N1 Muting) Peripheral Operating Temperature 10 to 55(Celsius) Protection/Enclosure IP40 IP55 (optional) Wall Mounting Type Housing When it is used together with the AMS, speed can be monitored, thus, safety will be improved. * AMS is a magnetic scale sensor designed to changeover the speed to low-speed and to identify the speed.
