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

A horizontal metal extrusion press has a tool cassette (13) for a tool set composed of a die (134), a die holder (32) and at least one pressure ring (36), displaceable horizontally along guide rails (10,11) transversely to the press axis between an extrusion position (P) on the press axis and a changing position (W) spaced horizontally from the press axis, and replaceable by a second cassette in the changing position. The cassette has an upwardly open U shape to receive the tool set. A locking piece (14) for retaining the tool set can move in a vertical guideway (22) in the upper guide rail (10), to an upper position above the opening of the cassette and to a lower position inside the opening for closing the opening. The cassette opening has an internal bead (29), and the die holder has a corresponding annular groove. The locking piece is guided on the beads along the sides of the cassette opening.

A wire coiler with a rotating winding drum which can be immersed in a water tank as a rotational body having the greatest possible smoothness in order to avoid energy-dissipating turbulence of the water in the tank includes a winding drum (1) open towards the top and formed by outer and inner spaced casings (2, 3), and a base (4) connecting the casings and a vertical rotatable shaft (8) connected by flanges (5, 7) to the drum. The inner casing of the winding drum is breached by vertical slots (16), and an annular disc (15) inserted into the winding drum for supporting the turns of the wire coil being formed is connected to a lifting device (19, 21) by crosspieces (17) engaging through the slots, whereby the lifting device raises the supporting surface of the disc to a level with the transfer plane of the wire coils. A lifting sleeve (19) connected to the stationary lifting device (21) surrounds the shaft and has an annular groove (20) which engages the inner ends of the crosspieces to form a rotatingly movable, axially fixed connection, and is movably arranged in the annular space within the inner casing.

Method for taking up a billet produced in the extrusion or tube-making

For recycling the dies and pressure plates, in an extrusion press designed to perform both direct and indirect extrusion, a common conveyor extends beside the press between a device for stripping extrusion residue from the dies, and a device for separating extrusion residue from pressure plates. A first transfer arm is provided to transfer a pressure plate and direct extrusion residue from the press axis to the conveying means for conveyance to the pressure plate-separating device. The same transfer arm serves to transfer stripped dies from the conveying means to the press axis. A second transfer arm removes the die, pressure plate and extrusion residue after indirect extrusion, to the conveying means, which conveys the die to the die stripper, and the pressure plate and extrusion residue to the device for separating the extrusion residue from the pressure plate. Separated pressure plates are recycled to a magazine and then to the press axis for re-use.
