length.
WIRE STOP GAUGE - The positioning of the wire stop gauge is adjusted
automatically by means of a servomotor governed by the processing unit. A
resolver guarantees the perfect positioning of the feed stop.
Corrections of cut-off lengths may be performed during machine
operation.
NEW ACTIVATOR to release the lever for the transformation of the last
station from a forming station to a trimming station by mean of a
hydraulic linear cylinder in replacement of the traditional rotating
arm.
MULTIPLE PROFILE CAM fitted on the last station for “forming” and
“trimming” kick-out. The type of kick-out required is selected by simply
turning the cam and locking it into the new position, through hydraulic
control and a new gear facilitating the technician to find the correct
profil with a simple key.
TRANSFER UNIT LIFTING with an hydraulic cylinder.
NEW DRIVING SYSTEM OF TRANSFER with slide and automatic engagement.
Option: TRANSFER ASSIST SYSTEM support device for pieces with a complex
shape in die kick-out phase. The system consists of support fingers,
perfectly timed with the motion of the transfer and of the kick-out
rods, brought about by a direct link with the rods and a Desmo Drive
system of double cams which controls the lateral movement.
ELECTRONIC HANDWHEEL : with the intention of assisting best the tool
setters in the delicate moment of tool and timing adjustments, SACMA
provides an electronic handwheel to move the whole machine at slow
motion in order to check for correct timing of the transfer fingers with
respect to the heading slide, avoiding dangerous collisions. The
heading slide can be stopped in any position avoiding jogging the
machine and damaging the main clutch/brake unit.
