Working principle:
The bell housing (8) and piston (10) can be compared to a double acting hydraulic ram. Crimping consists in
transforming a linear displacement at constant speed, that of the piston (10), into a two speed radial displacement:
resulting in a rapid approach speed and a slower crimping speed.
These two speeds are obtained via two slopes on the piston (10) and the die-carriers (6). The gentle slope en-
sures, for equal thrust on the piston (10), a slower displacement and higher crimping power.
The main elements of the crimper, made from special steel,
are heat treated in order to ensure that they will

high
stresses, and to reduce wear through
contact or friction.
Guidance in movement is ensured via two composite rings (made from bronze-charged teflon).
Sealing is obtained through 3 composite joints (made from PTFE). Also, in the unlikely event of any leaks, an oil
trap ring (12) at the rear of the bell housing directs oil back to the tank. A similar device is incorporated into the face
flange (5).
The numerical crimp adjuster, mechanically activated by the hollow piston (10), electrically stops the crimping
operation. For that purpose, it is equipped with a microswitch (3) which
activates the control valve.
Adjustment of the crimp diameter is via a micrometer (2).
Rotation of the micrometer changes the contact rod position (4), thereby allowing for precise adjustment of the final
crimp diameter.
