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.

Horizontal metal extrusion press

Apparatus for separating pressure plates from extrusion residues formed when metal is extruded so as to leave a thin shell of metal residue surrounding a pressure plate used to force the metal through the extrusion die comprises a device for pushing the pressure plate between a pair of stripping cutters which are urged resiliently against the shell on opposite sides of the path of movement of the pressure plate between the cutters, to that each stripping cutter removes a respective area of the shell from the pressure plate. For complete removal of the shell, the pressure plate may be retracted from between the cutters, turned to present a fresh portion of shell to the cutters, and then again fed between the cutters. A device may also be provided for shearing off extrusion residues at one or both ends of the pressure plate.
