DSP LASER AP with MCS
12. Residual risks
12.1. Risks typical of the laser source
The presence of a laser beam, even if with very low power, could directly or indirectly make
the use of the device dangerous.
The eye protection is however ensured, even in absence of DPI, by the eye defensive
reactions, as the eyelid reflex.
12.2. Blanking
The protection system DSP LASER AP has been designed to protect the operator from the
dangers due to the closing movement of the tools of a press brake. The detection area is
subdivided in a front, a central and a rear area. The front area avoids the squashing of the
operator’s fingers between the front part of the punch and the die or the objects present in
the movement area (e.g. bottom of the box), while the rear area avoid the squashing
between punch and backgauge.
The system is equipped with operating modes which allow the inhibition of the front and/or
rear detection area even during the use of the fast approaching speed. In this way, the
function protecting the front and/or rear area is not operating and the residual risks
highlighted in the following figure are introduced.
Figure 67
In order to reduce the residual risks, it is necessary to use proper organization measures
and a correct choice and installation of the tools.
To limit the risk of squashing between punch and dies, it is good thing to use punches of
width equal to the width of the piece to work. In fact, in case of wider punches, a dangerous
area is created between punch and dies on the sides of the piece in processing.
