Definitions

the invention relates to a strand and tube press or metal extrusion press, which has a consisting of a cylinder spar and associated counter frame press frame in which a movable, a block receiver carrying block pickup holder and a movable stamping Traverse are provided, wherein in the cylinder spar a main or pressing cylinder is arranged, which receives in its cylinder housing at its front, supported by the stamping Traverse end provided with a ram pressing piston, and in which connected to a tank line cylinder housing a plunger hydraulic oil by means provided on a fixed to the rear end of the plunger rod slide plate is associated with supplying expansion tank, wherein the extending in the expansion tank linkage is connected to a arranged in the pressing direction behind the slide plate hydraulic supply.
An extruder of this type in which the tool, common pressure plate, die holder and die, having counter-spar is connected via tie rods or tension lamellae and pressure supports with the cylinder spar is through the DE 102 27 488 B3 known.
a metal extrusion press is known with a pressure vessel to the plunger or plunger attached to the master cylinder reservoir.
the rod carrying the slide plate is formed with a forward and retraction cylinder and a fixed outside of the end or rear wall of the surge tank hydraulic connection block.
the non-productive times must be minimized, in particular, the idler and the side of the cylinder associated with the Blockaufrichhalter, in which the block receiver or recipient is arranged, and the stamping cross member or strut associated idle and retreat with the highest possible speeds can handle.
the oil Upon completion of the pressing stroke and then initiated with appropriate reversal of the hydraulic unit backward movement of the plunger into its initial position in the cylinder housing, the oil then flows back into the balancing cylinder, ie the oil is pushed back and forth under pressure during operation of the tube and extruder.
the invention is therefore an object of the invention to provide a strand and tube press or metal extruder of the type mentioned without the disadvantages described, in particular, should reduce the hydraulic effort and shorten the non-productive times with a more compact, simpler design.
the linkage is designed with an integrated in the transition from the expansion tank to the master cylinder, the local inner diameter of the cylinder housing adapted, in the opening function a large annular area cross-section releasing filling valve is formed.
a large annular area cross-section releasing filling valve is formed.
the amount of hydraulic oil still required after the delivery for pressing the charged block to produce an extruded product can preferably be supplied from a tank or other pressure medium supply into the pressure chamber of the cylinder housing behind the plunger. When a tank is interposed, only a significantly lower pendulum volume is required.
a preferred embodiment of the invention provides that the filling valve consists of a filling valve cover, which is arranged on the linkage via a collar-like sliding bushing, and an annular bushing surrounding the bushing in the pressing direction behind the valve cover, the cylinder piston depending on the loaded with hydraulic oil piston side the sliding bush and thus brings the valve cover either in the closed position or in the open position.
the filling valve is integrated in the cylinder housing of a press frame, in which the stamping crosshead and the block pickup holder are driven by means of electric motors, preferably servomotors.
the very large, free flow cross-section of the filling valve makes this particularly suitable for operation of the tube and extruder with on the one hand switched servomotor drives for moving stamping post and Blockaufrichhalter and on the other hand for applying the required high compression and in particular pressing force during pressing of the block an extrusion product. For pressing operation so that only a significantly reduced hydraulics is needed. It is within the scope of the possibilities that can be achieved by the use of regenerative power units from the braking energy of the electro-hydraulic drive units energy conservation.
Fig. 1 essentially the base frame shown. This consists of a cylinder spar 2 and thus a tensioned on tension blades 3, not shown here, at the end of the tension blades 3 only indicated by the reference numeral 4 counter-spar. For frictional connection of these components continue to contribute pressure supports 5, which enclose the tension blades 3 between the cylinder spar 2 and the counter-spar 4. The pressure supports 5 are also still used to guide receiving a movable in the base frame stamping Traverse 6 and a movable Blocketzillonhalters 7.
a surge tank 15 At the rear end of the cylinder housing 9 of the cylinder spar 2 is a surge tank 15 and at the end or rear wall 16 is a cylinder unit or a hydraulic connection block 17 is screwed, the latter, for example, as executed from the EP 1 526 930 B1 known.
the strand and tube press 1 instead of with electric motors 12, 13 for the traversing and advancing movements of the stamping traverse 6 and the Blockaufrichhalters 7 with known, hydraulically actuated side cylinders and Auf technicallyverschiebezylindern be equipped.
the pressing piston 11 For pressing and compressing a block loaded in the block receiver 8, the pressing piston 11 has a pressing ram 18.
a central filling valve 19 is formed, which consists of a large-scale valve cover 20 and a ring cylinder 21 for Gearventilbetuschist.
This in Fig. 3 shown as an enlarged detail filling valve 19 is mounted on a at the rear end of the plunger 11, extending into the surge tank 15 and there a slide plate 22 supporting linkage 23 with the interposition of a collar-like bushing 24, on which also the ring cylinder 21 sits arranged.
