warning!
!
when bending busbars, swinging parts can be a risk for cutting or crushing parts of the body.
• ensure that no persons or objects are present in the work area.
• In a dangerous situation, press the red emergency stop switch on the unit or alternatively
the foot-operated switch beyond the first pressure point to stop the operation!
• Set the selector switch of the unit to "Bend".
• Insert the bending die (23) in the tool holder of the load piston and tighten the locking screw (22).
• Insert the electronic angle indicator (24) in the half-open hole of the main body.
• Insert the plug (28) of the connection cable in the socket (27) behind the work block.
• Set the desired bending angle at the setting screw (25) using the angle scale (26).
• Hand-tighten the setting screw (25).
note:
when bending busbars, a plastic (permanent) and an elastic (spring-back) deformation of the
workpiece occurs. to compensate the elastic bending component and a spring-back of the
material, the bending angle should always be set 1 - 3° greater than the desired angle.
• Mark the bending line on the workpiece.
Alternatively, the length stop can be set appropriately on the unit.
• Adjust the height of the main body with a rotary knob and align the bending die centred
with the workpiece.
Fig. 6: Alignment of the workpiece
note:
there is the risk with non-centred bending of the material that the bending die breaks,
jams or the unit main body is damaged.
• ensure that the material is inserted correctly centred for the bending operation.
• Place the workpiece between the bending die and the bending mandrel. The material must lie flat
on both table tops. The busbar must be positioned so that the centre of the bending corresponds
to the laser point or the side edge is aligned at the set limit stop.
• Close the protective hood.
note:
the protective hood is connected with an internal safety switch.
the work operation cannot be started when the protective hood is open.
the operation can be stopped at any time by lifting the protective hood.
