Definitions
- the invention relates to a Clusterarman für usues for the intermediate roll sets of 18 HS rolling stands, wherein between the service-side chock and the drive-side chock side of the intermediate roll pivotable cluster arms are arranged, in which the lateral support rollers are integrated to support the work rolls in the frame.
- pivotable cluster arms are arranged between the service-side chock and the chocks on the side of the intermediate roll (inlet and outlet sides) in which the lateral support rolls for supporting the slim work rolls are integrated in the framework.
- the purpose of the support rollers integrated in the cluster arms is to prevent the deflection of the work roll and to realize the horizontal offset (HS) of the work roll to the intermediate roll with the aid of the support bridge adjustment arranged behind it.
- the pivot axis which is fixedly connected to the cluster arm, completely guided by the chocks to the outside and held with holding blocks, so that the axle can rotate in the chocks.
- the retrieval of the cluster arms into the defined "center position" is realized by means of spring packs projecting through the chock pivot axis of the cluster arm, the cluster arm in the desired Position is pressed.
- This arrangement requires the assembly and maintenance of the intermediate roll set with the cluster arms increased effort because the removal of the holding blocks and spring assemblies at each disassembly and reassembly of the holding blocks and spring assemblies, and the setting of the spring assemblies for establishing the central position of the cluster arms in the Rolling workshop is required.
- the object of the invention is to provide a Clusterarman extract, which greatly simplifies the assembly and maintenance.
- a lock for the cluster arm and a stop with return spring is arranged as a compact unit acting in the region between cluster arm and chock on the pivot pin.
- the pivot pin fixedly connected to the cluster arm cooperates with a locking tab serving as a detent, which is designed such that when the pivotable locking tab fastened to the chock is pivoted in, the cluster arm is axially locked with respect to the chock , but still remains pivotable.
- the pivotable locking tab can be fixed in the closed state with a fixing screw.
- the pivotable locking tab can be pivoted open, the cluster arm being released, so that the installation piece can be axially extended.
- a stop piece is attached to the outer ring of the pivot pin, which pivots with the Clusterarm, wherein the pivoting movement of the Clusterarms is limited to the outside by the Verriegelungsla- see to which the stop piece is supported in the case.
- the pivoting movement of the cluster arm is inwardly by a return spring is receivable, wherein, if no forces acting on the cluster arm from the outside, the return spring back the cluster arm, press until the stop member abuts the locking tab.
- the locking of the cluster arms and the stop with return spring are arranged as a compact unit in the area between cluster arm and chock, in each case at both ends.
- the pivot pin fixedly connected to the cluster arm is designed so that when a pivotable locking tab attached to the chock is pivoted in, the cluster arm is axially locked to the chock, but still remains pivotable.
- Fig. 1 shows the representation of the locking of the cluster arm with the chock
- Fig. 2 shows the representation of the lock and stop with return spring.
- the pivot pin 3 is arranged, about the axis of the cluster arm 2 can pivot.
- the fixedly connected to the Clusterarm 2 pivot pin 3 is designed so that when a mounted on the chock 1 pivotable locking tab 4 is pivoted, the Clusterarm 2 is axially locked to the chock 1, but still remains pivotable.
- the pivotable locking tab 4 is fixed in the closed state with a fixing screw 5.
- the pivotable locking tab 4 can be pivoted open, and releases the cluster arm 2, so that the built-in piece 1 can be extended axially.
- a stop piece 6 is fixed, which pivots with the cluster arm 2.
- the pivotal movement of the Clusterarms 2 to the outside is limited by the locking tab 4, to which the stopper piece 6 is supported in the case. This position is that which the cluster arm 2 must assume when changing the rolls.
