1 IntroductionThe LAND Aluminium Extrusion & Quench Thermometer Actuator is a motorised, operator controlled, mounting unit intended for use at the die exit or quench exit on aluminium extrusion presses.

It is used in conjunction with the AET/AQT integral alignment laser, to control the position of the thermometer target spot.

It allows for rapid and precise alignment following die changes, to reposition on multicavity strands or to maximise the signal strength (emissivity indication) on narrow sections.

The actuator unit is controlled remotely from a small handset which features individual push buttons for the motion directions. A third (smaller) handset button also allows for remote triggering of the AET/AQT laser alignment and is powered direct from the actuator control unit.

The handset is connected to the actuator control unit via a 12m length of screened cable.

A mechanical clutch and angular travel limiter plate ensure that no excessive movement can occur to strain pipes or cables.

3 MountingThe AET/AQT Actuator is intended for mounting the AET thermometer onto the press face or suitable near-by part of the press superstructure. It may also be used, where applicable, for the alignment of a quench (AQT) thermometer when mounted at the exit of a quench box or nearby structure, to allow for aiming onto sections exiting the quench.

Fig.2showsthemountingplateandfixingpointdimensions.Theplateismountedontotheselectedstructureusingaminimumof4xM8screwsfittedwith either nyloc nuts or anti-vibration washers.

The remote handset controls the operation of the actuator and may be separated from it by up to 12 metres. The connecting cable should be routed away from moving machinery and the handset positioned at a convenient locationatwhicheitherthelaserindicatorspotontheemergingprofiles,orthe signal strength indicator (emissivity) reading, may be clearly seen.

Before use, ensure that all cable glands are tightened to prevent the ingress of moisture, dirt or any other contamination.

For typical die exit use, the plate is normally mounted such that the distance from the front of the thermometer to the extrusion axis is approximately 1 to 1.5 metres. The thermometer’s viewing axis should be set (see section 6 - Alignment) so that the target spot is ‘upstream’ of any air blowers or water sprays and therefore the indicated temperature is as close to that at the die exit as possible. Also refer to the AET & AQT thermometer operating instructions for further advice on alignment.

NOTE

When mounting or positioning the actuator unit, the suggested orientation should be as shown in Fig. 1. Alternatively, the actuator may be positioned or mounted in any orientation as dictated by services requirements or space availability.


NOTE

COMPATIBILITY WITH EXISTING AETS/AQTS SYSTEMSAn additional ball swivel is supplied as an accessory to allow compatibility with existing AETS and AQTS systems. The thread on this ball swivel matches the mounting holes in the environmentally protective jackets supplied with AETS and AQTS thermometers.To change the ball swivel type, loosen the ball swivel thread lock nut and unscrew the instrument off the ball swivel thread. Undo, remove and retain the ball clamp nut. Replace the ball swivel, locate and tighten the ball clamp nut. Mount the instrument onto the ball swivel thread and secure using the thread locknut. Slightly loosen the ball swivel clamp nut, align the instrument with the intended target area and re-tighten the clamp nut. For alignment details, see section 6.0.

4 Adjustment of the Angular Travel LimiterFor smaller presses it is recommended that the maximum angular displacement is limited to 20° (i.e. ±10° from the mean position). The unit is supplied as standard with a 30° (±15°) limiter, however, an alternative 20° (±10°) limiter is also included.

To decide on the angular travel required, measure the distance form the mounting spindle/ball joint to the axis of the extrusions at the target position. Call this dimension ‘x’. Determine the maximum width of the largest possible extruded section that could be produced and call this dimension ‘y’.

Calculate the value of the angle given by utilising one of the following two formulae:

(Thecalculatedfigureiscommontobothformulae.)

Takethecalculatedvalueandmultiplyby2.Ifthisfigureexceeds16°thenthe standard 30° limiter is recommended.

To change the adjustment limiter, perform the following operation:

(Note that the following instructions may be carried out before or after mounting). Using the handset controls, adjust the rotation of the moving spindle/jacket etc. until the notch on the pivot plate aligns with the inscribed line on the limiter plate (see Fig. 3). At this point it is possible to loosen and remove the 2x M6 cap head screws which hold the limiter plate in position onto the gearbox casing, as well as the M6 x 20 screw which acts as the limiter. The 30° plate may then be substituted by the 20° plate also supplied. Replace and re-tighten the cap head screws.

6 Primary AlignmentThis is the process by which the thermometer is aimed to the required point on the extrusion axis, with the actuator in the nominal mid position. This procedure is carried out by adjusting the ball joint mechanism.

6.1 Alignment ProcedureUsing the buttons on the hand set, move the pivot plate of the actuator unit to the mid-travel position. This is indicated (see Fig. 3) by aligning the notch in the plate with the inscribed line on the limit plate, mounted on the gearbox casing.

At this point, the two holes in the pivot plate will align with the tapped holes in the limit plate. Insert the 2xM4 cap head screws into these holes and tighten. This locks the pivot plate into the central position. Using either the signal strength (emissivity) indication from the thermometer (viewing an on-axis extrusion), or the laser indicator spot, move the thermometer jacket by hand, until the required alignment is attained.

Tighten the 36mm ball joint locking nut as well as the M16 locknut to secure the threaded spindle into the protection jacket.

Remove the 2xM4 cap head screws to allow the unit to be operated from the handset if required.

NOTE

It is recommended that the notes in Section 1 of the AET/AQT Operating Instructions, are fully read before proceeding with the following instructions.


7 Cleaning and Maintenance Instructions

7.1 GeneralThe actuator unit should not require any special regular maintenance. It is, nevertheless, recommended that in order to prevent the ingress of any dirt or contamination, the external surfaces should be periodically wiped with a damp cloth. The unit should not, under any circumstances, be subjected to a high pressure water hose or immersed in water.
