Abstract: A tube or metal extrusion press has a stationary press frame formed by a main housing, a counter housing, a billet support carrying a billet holder, and a ram cross-member movable in the press frame between the housings. A piston-cylinder unit has a cylinder on the main housing, a piston in the cylinder, and a ram stem extending between a front end of the piston and the ram cross-member. An equalizing reservoir supplies hydraulic fluid to the piston, and a transfer passage extends between the reservoir and the cylinder rearward of the piston. A fill valve has a displacement sleeve on a rod and carries a ring piston and a fill valve body movable centrally of the cylinder in the transfer passage between an open position in which the passage has a large annular flow cross-section and a closed position in which the valve body blocks the passage.

Abstract: If a mandrel for extruding metal pipes, having two axially offset pressing surfaces with different radial embossing and having a transition region between these two pressing surfaces has a support surface in the transition region then the negative effect of narrowing, which arises owing to the mandrel shifting from a first pressing position, in which the first of the two pressing surfaces interacts with a die, to a second pressing position, in which the second pressing surface interacts with the die, can be minimized.

Abstract: In a method for operating an indirect extrusion press, wherein the indirect extrusion press includes an indirect punch having a tool head that can be accommodated on the indirect punch, a closure piece, and a longitudinally movable block holder having a material block accommodation for accommodating a material block, after pressing a material block and forming a shell in a shell chamber, a tool head to be replaced is pushed out of the block holder by a tool head to be inserted, so that very operationally reliable removal of a shell formed during one or more pressing procedures is possible. For this purpose, an indirect extrusion press can have a maximal distance between a closure piece and an indirect punch that corresponds at least to the sum of the expanses of the tool head and of the block holder in the movement direction.

Abstract: The invention relates to an extruder and tube extruder or metal extrusion press (1) having a press frame consisting of a cylinder bar (2) and a counter bar (4) connected thereto, in which a movable block receiver holder (7) supporting a block receiver (8) and a movable plunger traverse (6) are provided, wherein a main or pressing cylinder arranged in the cylinder bar (2) holds in its cylinder housing (9) a pressing piston (11) that is supported at its front end by the plunger traverse (6) and is furnished with a pressing plunger (18), and wherein the cylinder housing (9) connected to a tank line is associated with a compensation container (15) supplying the pressing piston (11) with hydraulic oil by means of a pusher plate (22) provided on a connecting rod (23) connected to the rear end of the pressing piston (11), wherein the connecting rod (23) extending in the compensation container (15) is connected to a hydraulic supply arranged upstream of the pusher plate (22) in the pressing direction (14). The considerable hydraulic expense for such an extruder, and in particular the downtime, is to be markedly reduced or shortened, with a simultaneously compact and simple construction. For this purpose the connecting rod (23) is constructed with an integrated filling valve (19) provided in the transition from the compensation container (15) to the main cylinder, adapted to the inside diameter of the cylinder housing (9) there and exposing a large annular cross-sectional area when it opens.
