backgauges with high sufficient to keep the sheet pushed by the operator (avoid
movable stops easily retractable).
If the piece is supported by hand during the bend, never put the hands within areas of
possible squashing between the piece and the machine parts (e.g. punch or upper table)
and among the tools.
11.2.2. Blanking
The protection system DSP LASER has been designed to protect the operator against the
dangers due to the closing movement of the tools of a press-brake. The detection area is
subdivided in a front area, a central area and a rear area. The front area forbids 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 avoids
the squashing between punch and rear mechanics.
The system is provided with operating modes which allow the inhibition of the front and/or
rear detection area even during the fast approach speed. In this way, the protection of the
front and/or rear detection area is lost and the residual risks detailed above arise.
Fig. 11.2 Residual risk when bending the boxes
In order to reduce the residual risks, organization measures and a correct choice and
installation of the tools must be adopted.
In order to limit the risk of squashing between punch and die, it is appropriate to use punch
with a width equal to the width of the piece to work. In case of wider punches, in fact, a
dangerous area arises between the punch and the dies on the sides of the piece in
processing.
In order to limit the surface of squashing between punch and top edges of the box with
particular shape and internal bottom of the box, it is necessary to use punches with a
reduced surface projecting towards the operator, or to install them with this surface towards
the back of the press-brake (e.g. swan-neck tools).
