Abstract

A wire mill in block construction, so-called wire block, having driving bevel gears 5, 6, which are arranged on a longitudinal shaft 4 and can be coupled selectively to the longitudinal shaft via clutches 16, 17, and having slowly running auxiliary drives 20, 21 for each driving bevel gear, which become effective upon decoupling of the associated driving bevel gear, in order to keep switched-off drive trains 8, 10, 14 for inoperative rolls 12 in rotary movement. The auxiliary drives are switched in via axially displaceable driving wheels, preferably bevel gear-like driving wheels 22, 23, which are brought into a driving connection with the driving bevel gears, only if the associated clutch 17 is disconnected. <IMAGE>

Description

Die Erfindung betrifft ein Drahtwalzwerk in Blockform, sogen. Drahtblock, mit mindestens einer angetriebenen Längswelle, von der über Kegelradgetriebe Querwellen zum Antrieb der Gerüste abgezweigt sind, wobei die treibenden Kegelräder auf der Längswelle frei drehbar gelagert und über Schaltkupplungen selektiv mit der Längswelle kuppelbar sind. Ein derartiges Drahtwalzwerk ist in der DE-OS 24 46 905 beschrieben und hat den Vorzug, Gerüste oder Walzscheiben von der Auslaufseite her additiv abschalten zu können, ohne Rücksicht auf eine gesteigerte Drehzahl der Längswelle beim Walzen von größeren Querschnitten Schwingungsprobleme im Bereich der nicht benötigten Walzantriebe auszuschalten.The invention relates to a wire rolling mill in block form, so-called. Wire block, with at least one driven longitudinal shaft, from which transverse shafts for driving the scaffolding are branched off via bevel gear transmissions, the driving bevel gears being freely rotatably mounted on the longitudinal shaft and selectively couplable to the longitudinal shaft via clutch couplings. Such a wire rolling mill is described in DE-OS 24 46 905 and has the advantage of being able to additively switch off scaffolding or rolling disks from the outlet side, regardless of an increased speed of the longitudinal shaft when rolling larger cross sections, vibration problems in the area of the unneeded roller drives turn off.

Da jedoch Eigenschwingungen in einem mehrgliedrigen Antriebssystem eines Drahtwalzwerkes in Blockform der vorbeschriebenen Art nicht zu vermeiden sind, besteht die Gefahr, daß durch diese Eigenschwingungen in den Lagern und an den Verzahnungen abgeschalteter und somit stillstehender Gerüste bzw. Walzscheiben Stoßmarkierungen hervorgerufen werden. Diese Stoßmarkierungen können einen unruhigen Lauf innerhalb der verzweigten Antriebe bewirken, der um so ausgeprägter ist, je länger eine abgeschaltete Gerüststelle den Stoßmarkierungen aus den Eigenschwingungen der mitlaufenden Antriebe ausgesetzt ist. Dieser unruhige Lauf kann sich auf das Walzgut nachteilig auswirken.However, since natural vibrations in a multi-unit drive system of a wire rolling mill in block form of the type described above cannot be avoided, there is a risk that these natural vibrations in the bearings and on the toothing of switched off and thus stationary stands or roller disks will cause impact markings. These impact markings can cause a restless run within the branched drives, which is more pronounced the longer a switched-off scaffold point is exposed to the impact markings from the natural vibrations of the moving drives. This restless run can have an adverse effect on the rolling stock.

Der Erfindung liegt von daher die Aufgabe zugrunde, Stoßmarkierungen an abgeschalteten abgezweigten Antrieben für Gerüststellen bzw. Walzscheiben zu vermeiden. Die Lösung dieser Aufgabe besteht darin, daß die treibenden Kegelräder, die lose auf der Längswelle gelagert sind, von langsam laufenden Zusatzantrieben antreibbar sind, die jeweils ein Treibrad umfassen, das durch Axialbewegung mit dem zugehörigen Kegelrad in Antriebsverbindung gelangt, wobei eine Sicherung vorgesehen ist, die die Axialbewegung des langsam laufenden Treibrades verhindert, wenn die dazugehörige Schaltkupplung für das treibende Kegelrad geschlossen ist, und die ein Einrücken der Schaltkupplung verhindert, wenn das langsam laufende Treibrad mit dem Kegelrad in Antriebsverbindung ist. Hierdurch wird erreicht, daß die Kegelradstufe und die Querwellen einer Gerüststelle oder eines Walzscheibenpaares ständig langsam umlaufen, wenn sie von der Längswelle abgekuppelt sind. Es ist denkbar, daß die langsam laufenden Treibräder ebenfalls Kegelräder sind, die durch Axialbewegung mit dem zugehörigen Kegelrad auf der Längswelle in Eingriff gelangen. Vorzuziehen ist jedoch, daß die langsam laufenden Treibräder jeweils als fliegend gelagerte, kegelradähnliche Reibräder ausgebildet sind, deren sich quer zu der Längswelle erstreckenden Antriebswellen entgegen einer nachhaltigen Kraft vom Kegelrad weg axial anstellbar sind.The invention is therefore based on the object of avoiding impact markings on switched off branch drives for scaffolding points or rolling disks. The solution to this problem is that the driving bevel gears, which are loosely mounted on the longitudinal shaft, can be driven by slow-running auxiliary drives, each of which comprises a driving wheel which, by axial movement, comes into drive connection with the associated bevel gear, with a fuse being provided, which prevents the axial movement of the slow-running driving wheel when the associated clutch for the driving bevel gear is closed, and which prevents the clutch from engaging when the slow-running driving wheel is in drive connection with the bevel gear. It is hereby achieved that the bevel gear stage and the transverse shafts of a scaffolding point or a pair of roller disks constantly rotate slowly when they are uncoupled from the longitudinal shaft. It is conceivable that the slow-running drive wheels are also bevel gears, which come into engagement with the associated bevel gear on the longitudinal shaft by axial movement. However, it is preferable that the slow-running drive wheels are each designed as overhung, bevel gear-like friction wheels, the drive shafts of which extend transversely to the longitudinal shaft and are axially adjustable away from the bevel gear against a sustained force.

Eine bevorzugte weitere Ausgestaltung des langsam laufenden Zusatzantriebes ist in den Patentansprüchen 3 und 4 angegeben. Die Sicherung zur gegenseitigen Sperrung der Kuppelvorgänge sowohl des langsam laufenden Treibrades als auch der Schaltkupplung besteht zweckmäßig darin, daß der Schalthebel der Schaltkupplung und derjenige des Zusatzantriebes miteinander verbunden sind, so daß die beiden Kuppelvorgänge zwangläufig im entgegengesetzten Sinne vor sich gehen.A preferred further embodiment of the slow-running auxiliary drive is specified in claims 3 and 4. The backup for the mutual locking of the coupling processes of both the slow-running driving wheel and the clutch consists of the fact that the shift lever of the clutch and that of the auxiliary drive are connected to each other, so that the two coupling processes inevitably go in the opposite sense.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt, und zwar zeigt

  • Fig 1 die beiden letzten Gerüststellen eines Drahtblockes mit ihren selektiv ausschaltbaren Antrieben, im Längsschnitt durch die Lagerstellen, sonst in Ansicht, und
  • Fig 2 einen langsam laufenden Zusatzantrieb im vergrößerten Maßstab und im Längsschnitt.
In the drawing, an embodiment of the invention is shown, namely shows
  • Fig. 1 shows the last two scaffolding points of a wire block with their drives can be selectively switched off, in longitudinal section through the bearing points, otherwise in view, and
  • Fig. 2 shows a slow-running auxiliary drive on an enlarged scale and in longitudinal section.

Der Drahtblock umfaßt ein Gehäuse 1 mit einer darin gelagerten Längswelle 4, die auslaufseitig von einem nicht dargestellten regelbaren Gleichstrommotor über ein Vorgelegegetriebe 2 angetrieben ist. Auf der Längswelle 4 sind frei drehbar treibende Kegelräder 5, 6 gelagert, die mit getriebenen Kegelrädern 7 und 8 ständig im Eingriff stehen. Von den Kegelrädern 7 und 8 sind Querwellen 9 und 10 angetrieben, die an ihren Enden fliegende obere Walzscheiben 11 und 12 tragen. Die jeweils darunter befindlichen Walzscheiben sitzen an weiteren nicht sichtbaren Querwellen, die über gegenläufige Kammwalzen 13 und 14 miteinander gekuppelt sind.The wire block comprises a housing 1 with a longitudinal shaft 4 mounted therein, which is driven on the outlet side by an adjustable DC motor (not shown) via a countershaft transmission 2. On the longitudinal shaft 4, freely rotatable bevel gears 5, 6 are mounted, which are in constant engagement with driven bevel gears 7 and 8. Transverse shafts 9 and 10 are driven by the bevel gears 7 and 8 and carry upper rolling disks 11 and 12 at their ends. The roller disks located below each sit on further invisible transverse shafts which are coupled to one another via opposing comb rollers 13 and 14.

Auf der Längswelle 4 sind mitdrehende Schaltmuffen 16, 17 vorgesehen, die über Handhebel 18, 19 auf der mit einer Vielnutverzahnung versehenen Längswelle 4 verschiebbar sind. Jede Schaltmuffe 16, 17 hat eine Innenverzahnung, z. B. 17a, die mit einer Außenverzahnung 6a der Kegelräder 5 bzw. 6 in und außer Eingriff gebracht werden kann. Man erkennt, daß die Schaltmuffe 17 ausgerückt ist, womit das dazugehörige Kegelrad 6 abgekuppelt ist und die Gerüststelle mit der Walzscheibe 12 abgeschaltet ist. Die Schaltmuffe 16 hingegen ist eingekuppelt und dreht das Kegelrad 5 mit, so daß die Gerüststelle mit der Walzscheibe 11 in Betrieb ist.Rotating shift sleeves 16, 17 are provided on the longitudinal shaft 4 and can be displaced via the hand levers 18, 19 on the longitudinal shaft 4 provided with a multi-groove toothing. Each shift sleeve 16, 17 has an internal toothing, for. B. 17a, which can be brought into and out of engagement with an external toothing 6a of the bevel gears 5 and 6 respectively. It can be seen that the shift sleeve 17 is disengaged, with which the associated bevel gear 6 is uncoupled and the stand with the roller plate 12 is switched off. The shift sleeve 16, however, is engaged and rotates the bevel gear 5, so that the stand with the roller plate 11 is in operation.

Jedem auf der Längswelle 4 frei drehbaren Kegelrad 5 bzw. 6 ist ein Zusatzantrieb 20, 21 zugeordnet, die axial verstellbare kegelradähnliche Reibräder 22, 23 aufweisen. Man erkennt, daß das dem Kegelrad 5 zugeordnete Reibrad 22 nach oben gestellt ist, wogegen das Reibrad 23 des Zusatzan- triebes 21 gegen einen konischen Bund 6b des Kegelrades 6 angestellt ist. Der Zusatzantrieb 21 vermag also das entkuppelte und frei drehbare Kegelrad 6 langsam zu drehen. Damit dreht sich auch der abgezweigte Antrieb 8, 10 und 14 für das Walzscheibenpaar 12, das an sich als letztes Gerüst abgeschaltet ist. Zur gesicherten, wechselweisen Betätigung der Zusatzantriebe 20 bzw. 21 mit den dazugehörigen Schaltmuffen 16 bzw. 17 sind die Schalthebel 18 bzw. 19 über Kuppelstangen 25 mit den Schalthebeln 26, 27 der Zusatzantriebe 20, 21 verbunden dergestalt, daß mit dem Einrücken beispielsweise der Schaltmuffe 16 das Reibrad 22 von der konischen Gegenfläche 5a des Kegelrades 5 abgehoben wird und umgekehrt nur dann zum Reibkontakt angestellt werden kann, wenn die Schaltmuffe vom Kegelrad entkuppelt ist, was für die Schaltmuffe 17 und das Reibrad 23 zutrifft.An additional drive 20, 21, which has axially adjustable bevel gear-like friction wheels 22, 23, is assigned to each bevel gear 5 or 6, which is freely rotatable on the longitudinal shaft 4. It can be seen that the friction wheel 22 assigned to the bevel gear 5 is set upwards, whereas the friction wheel 23 of the additional gear drive 21 against a conical collar 6b of the bevel gear 6 is employed. The auxiliary drive 21 is thus able to slowly rotate the disengaged and freely rotatable bevel gear 6. This also the branched drive 8, 10 and 14 rotates alzscheibenpaar 12 for the W, which is switched off in itself as the last frame. For secure, alternate actuation of the additional drives 20 and 21 with the associated shift sleeves 16 and 17, the shift levers 18 and 19 are connected via coupling rods 25 to the shift levers 26, 27 of the additional drives 20, 21 such that with the engagement of, for example, the shift sleeve 16, the friction wheel 22 is lifted off the conical counter surface 5a of the bevel gear 5 and, conversely, can only be made to make frictional contact when the shift sleeve is uncoupled from the bevel gear, which applies to the shift sleeve 17 and the friction wheel 23.

Fig 2 zeigt den Zusatzantrieb 20 für das Kegelrad 5 in vergröBerter Darstellung und im Schnitt, jedoch hinsichtlich der Anordnung des Schalthebels 26 um 90° gedreht. Das langsam laufende Treibrad des Zusatzantriebes 20 ist als fliegend gelagertes, kegelradähnliches Reibrad 22 ausgebildet, das auf einer sich quer zu der Längswelle 4 erstreckenden Antriebswelle 30 sitzt. Die Antriebswelle 30 hat ein längsverzahntes Ende 30a, das in eine innenverzahnte Büchse 31 eingreift, die von einem Hydromotor 32 angetrieben ist. Der Hydromotor ist an einen Gehäusedeckel 33 angeflanscht, der ein zylindrisches Gehäuse 34 mit einer zylindrischen Außenbüchse 35 abschließt.2 shows the additional drive 20 for the bevel gear 5 in an enlarged representation and in section, but rotated by 90 ° with respect to the arrangement of the shift lever 26. The slow-running drive wheel of the additional drive 20 is designed as a cantilever-like friction wheel 22 which is mounted on the fly and which is seated on a drive shaft 30 which extends transversely to the longitudinal shaft 4. The drive shaft 30 has a longitudinally toothed end 30a which engages in an internally toothed bush 31 which is driven by a hydraulic motor 32. The hydraulic motor is flanged to a housing cover 33, which closes a cylindrical housing 34 with a cylindrical outer sleeve 35.

Die Antriebswelle 30 ist innerhalb einer zweiteiligen, axial verstellbaren Büchse 36, 37 gelagert, wobei das obere Teil 37 der Büchse einen Bund 37a als Widerlager für eine Druckfeder 38 trägt, die sich am Gehäusedeckel 33 abstützt. Zum axialen Verstellen der im übrigen gegen Mitdrehen gesicherten Büchse 36, 37 samt Antriebswelle 30 dient ein Stellexzenter 39 einer Stellwelle 40, die quer zur axialen Verstellrichtung der Antriebswelle 30 in dem Gehäusemantel 34 gelagert und durch den Handhebel 26 verstellbar ist. Der unter der Kraft der Feder 38 stehende Bund 37a des Büchsenteils 37 findet an dem Stellexzenter 39 seinen Anschlag, so daß er je nach Stellung des Exzenters 39 das langsam laufende Reibrad 22 an der konischen Gegenfläche 5b des Kegelrades 5 treibend zur Anlage gelangt oder in der Fig 2 dargestellten Leerlauflage ist.The drive shaft 30 is mounted within a two-part, axially adjustable bushing 36, 37, the upper part 37 of the bushing carrying a collar 37a as an abutment for a compression spring 38 which is supported on the housing cover 33. A positioning eccentric 39 of an adjusting shaft 40, which is transverse to the axial direction of adjustment of the drive shaft 30 in the housing jacket, is used for the axial adjustment of the bush 36, 37, which is secured against rotation, along with the drive shaft 30 34 stored and adjustable by the hand lever 26. The under the force of the spring 38 collar 37a of the bush part 37 finds its stop at the eccentric 39, so that depending on the position of the eccentric 39, the slow-running friction wheel 22 drives against the conical counter surface 5b of the bevel gear 5 or in the Figure 2 is the idle position shown.
