Abstract: A bar and tube extruding press for thrilling metal ingots into profiles, tubes, bars or the like includes a male die and a female die, through which a metal ingot can be pressed by the male die a container, and a driving device, in which the driving device has at least one main cylinder tor applying the main pressing force of the male die to the metal ingots, characterized in that on the one hand the driving device having at least one speed-controlled internal gear pump for providing the hydraulic oil to the at least one main cylinder, with which the at least one main cylinder can be driven, and at least one hydraulic advance and/or return cylinder for moving the male die in relation to the female die or at least one electrical drive for moving the male die in relation to the female die and with which the male die can be moved into a position in which the speed-controlled internal gear pump only then interacts with the at least one main cylinder in such a way that the main pressing force is applied to the mal

Abstract: The invention relates to extrusion and pipe presses (1), comprising a press frame consisting of a cylindrical spar (2) and a counter spar (4) connected thereto, in which a mobile billet container holder (7) supporting a billet container (8), which puts a billet (18) to be pressed, which was introduced by a loading device, into a press position in front of the counter spar (4) with the associated tool (38), and a mobile punch crosshead (6) are provided. In the cylindrical spar (2), a main cylinder, or press cylinder, is arranged, which in the cylinder housing (9) thereof receives a press piston (11), which at the front end thereof that is supported by the punch crosshead (6) is connected to a press punch (19). A compensation tank (15), which delivers hydraulic oil to the press piston (11) by way of a slider plate (28), is assigned to a main cylinder housing (9) connected to a tank line.

Abstract: A withdrawing device for a press that outputs an elongated workpiece in a direction has a first guide extending in the direction and carrying a first carriage movable by a first motor. A second guide extending in the direction on the first carriage carries a second carriage displaceable in the direction on the second guide by a second motor. The workpiece is clamped to the second carriage. A controller is connected to the first and second motors for shifting the second carriage in the direction at a speed independent of a speed of the first carriage while the first carriage is moving in the direction.

Abstract: Disclosed is a device (1) for withdrawing a bar (3) that has been produced in a bar extruder or pipe extruder (2). Said device (1) comprises at least one driven first carriage (4) that is movable in a linear direction along the direction of withdrawal (L) of the bar (3) and exerts a pulling force on said bar (3). A second carriage (5) which is movable in the direction of withdrawal (1) relative to the first carriage (4) is arranged on the first carriage (4). The bar (3) that is to be withdrawn is attached to the second carriage (5).
