The drawing below shows how to remove the screw from the front of the motor when
the motor is equipped with a screw cooling protection pipe.
Having removed the screw cooling conduit, mount the screw extraction mechanical
part (1) at the end of the protection pipe (2), using the threading intended for this
operation. Then insert a threaded steel rod (3) from the rear of the motor. Rotate the
threaded steel rod until it reaches the extrusion screw (4). Continue to rotate the rod
in order to push the screw out of the front of the motor.
4.5.3.
Rear side screw extraction with screw cooling (Execution R)
In execution R, torque motors are equipped with a patent pending mechanism
allowing the extraction of the extrusion screw from the rear of the motor. An internal
sealed protection pipe also allows the passage of an external water conduit for the
cooling of the extrusion screw through the motor.
Warning: The protection pipe is only intended to isolate the motor in
case of coolant leakage. It shall not be used directly as a coolant
conduit. Use an external system to convey the coolant to the screw.
Warning: When removing the extrusion screw from the rear of the
motor, the extrusion screw has to be clean to avoid material deposit
inside the motor.
