Definitions
- a winding tube is known, which is pushed onto an expandable coiler mandrel.
- the coiler mandrel is not spread; he then has only a minimum diameter.
- the mandrel is reduced again in its diameter, so that the sleeve can be removed.
- German Offenlegungsschrift DE 1 752 241 finally discloses an application for such reeling devices in connections with rolling mills. It is described there that the rolling plants are typically preceded and / or followed by a coiling device in order to select metal strips to be rolled. Roll up or store after individual rolling operations and temporarily store them later by processing.
- a rolling mill in particular a reversing stand (110) in a rolling mill, reels with not only one, but with two reel mandrels, each with a different diameter upstream or downstream.
- Initially thick metal bands are first wound onto large diameter reel mandrels to avoid the risk of cracking during bending. If the thickness of the metal bands has then been reduced after a few rolling operations, they are preferably wound on smaller diameter reel mandrels to achieve a higher coil weight with the same dimensions.
- the reel devices then each require a reel gear and a circuit in order, in accordance with the thickness of a respective currently rolled metal strip, to couple the reel mandrel, which is suitable on the basis of its diameter, with a drive motor.
- Such reel gears which are designed to drive at least two spatially separated reel mandrels, are larger, more complex and thus more expensive than a reel gear for controlling only one coiler mandrel. Furthermore, transfer devices are required in order to transport the rolled metal strip from and to a reeling device located farther away from the reversing stand.
- the object of the invention is to further develop a known rolling mill with a reversing stand and a reverbering reel and a known method for operating the reeling units in such a way that handling, in particular winding of metal strips whose thickness is during the rolling process, even without the risk of cracking with a reversing pel adopted with only one coiler mandrel is possible.
- a rolling mill has a winding tube changing device for Sliding a winding tube on the coiler mandrel before an intermediate securing of the metal strip and removing the winding tube from the coiler mandrel between two subsequent rolling operations when the thickness of the metal strip determined by the sensor device is still greater than the desired thickness, but already smaller than a predetermined thickness threshold value.
- the claimed changing device allows a fast assembly and disassembly of a winding tube on a single coiler mandrel reversible reel as needed. More specifically, the winding tube changing device allows the winding tube to be pushed on before a first rolling operation in order to provide an increased diameter for winding up the metal strip when the metal strip to be rolled is still relatively thick. Due to the increased diameter and larger metal strips can be wound without them, even if they are made of hard or brittle materials, a risk of cracking.
- the claimed use of the winding tube during operation of the rolling mill with Reversiergerüst advantageously allows the use of only one Reversierhaspel adopted with a simple reel gear for control of only one coiler mandrel.
- the investment costs as well as the mainte- nance and maintenance costs are only one for the reel unit Reel mandrel significantly lower than if the reel device would have a second coiler mandrel with a second drive shaft and a correspondingly complex constructed reel gear.
- the claimed winding tube changing device advantageously allows greater flexibility in the use of primary materials towards larger strip thicknesses.
- the claimed exchange sleeve device advantageously offers the possibility, now without much additional effort thicker metal bands gentle material without Risk of cracking.
- the winding tube has a clamping device for clamping one end of the metal strip at the beginning of a winding process.
- the clamping device can be adapted to different thicknesses of the metal strip to be clamped.
- the winding sleeve device advantageously has a telescopic device for coaxial displacement of the winding tube from an intermediate position to the coiling mandrel or from the coiler mandrel into the intermediate position.
- the winding tube changing device further comprises a pivoting device for pivoting the winding tube from an initial position to the intermediate position.
- the above object of the invention is further achieved by a method for producing a metal strip by means of a rolling mill.
- the advantages of this method correspond to the advantages mentioned above with respect to the claimed rolling mill.
- FIG. 3 shows a telescopic device as part of a winding tube changing device according to the invention.
- FIG. 2 shows a winding sleeve 134 designed according to the invention, as it is pushed onto the reel mandrels 132, 132 'if necessary, and clamped there. It serves to increase the minimum winding diameter and thus also allows the winding of hard and brittle materials with relatively large thickness, without causing a risk of cracking in these materials or these metal bands.
- the winding tube has a clamping device 134a, for example in the form of a clamping slot for clamping one end of the metal strip at the beginning of a winding process.
- the clamping device 134a may be designed for manual or hydraulic actuation. Preferably, it is designed to receive metal strips with different thicknesses.
- the two devices 140, 140 are basically of the same design, for which reason - for simplicity's sake - only the reference numeral 140 is used below:
- the winding tube changing device 140 is the first part a telescopic device 142 for coaxial displacement of the winding tube 134 from an intermediate position Z on the coiler mandrel 132 or from the coiler mandrel back to the intermediate position Z.
- the telescopic device 142 has a rail 142-1, to which the winding tube 134 is releasably attached.
- the rail 142-1 is slidably mounted with respect to the coiler mandrel 132 and thus enables a coaxial pushing or removal of the winding tube on or from the coiler mandrel 132.
- FIG. 4 illustrates the construction and functioning of a pivoting device 146 as an optional second part of the winding tube changing device 140.
- the pivoting device 146 serves to pivot the winding sleeve 134 from an initial position A to the intermediate position Z.
- the pivoting device 146 has a fixed stand 146-1 on which a support arm 146-11 is pivotally mounted. On the support arm 146-11, the winding tube 134 is releasably attached.
