ABSTRACT:
In a horizontal metal extrusion press to enable direct measurement of the alignment of the tools, the moving crosshead (9) and the receiver holder (12) in relation to the press axis, the tie rods (4) of the press frame (3) of high dimensional stability are provided with at least three clearance-measuring probes (25), which are directed at central angles of 120.degree. or less radially towards the press axis (X--X) and are centrally adjustable to a reference clearance from the press axis. The probes are disposed in radial planes (R2, R3, e.g.) in which they detect measuring surfaces (27, 28) provided on and centered at least on the receiver or receiver holder (12) and on the tools, in the working position and/or selected positions of the receiver holder and the tools. To enable the measurements to be effected without stoppages, it is advantageous to provide non-contact clearance-measuring probes, for example measuring on the basis of eddy current, laser or ultrasound.
