Definitions

  • the invention relates to a device for assembling, securing and dismantling a roller ring braced on a cantilevered roller shaft, the roller ring being radially braced by means of a clamping sleeve on a conical pin of the roller shaft.
  • Applications of the invention are seen in wire rod blocks and wire rod stands, for example CL stands (cantilever stands).
  • Clamping devices for the radial fastening of rolling rings on overhung roller shafts in wire rod blocks or wire rod stands are known in large numbers. Such generic devices are disclosed in DD 115 432 A, DD 119 144 A, DD 123 645 A, DD 141 466 A and DE 26 06 908 B1.
  • DD 115 432 A shows, for example, a clamping device which essentially consists of a bell-shaped base body and whose outer contour is formed by an annular pressure piece.
  • the pressure piece is in turn axially displaceable and can be clamped against the rolling ring (rolling disc) by clamping elements which are arranged in the base body.
  • the roller ring itself is mounted on the conical pin of the roller shaft via an adapter sleeve.
  • the base body furthermore has a cylindrical collar in the center, at the free end of which bayonet claws are arranged which engage in corresponding bayonet receptacles of the journal of the roller shaft.
  • the aforementioned clamping devices are certainly suitable for one satisfactory clamping of the roller rings on the pin of the roller shaft ensure and secure against axial displacement.
  • the invention is accordingly based on the object of a device Generic type to create, taking into account any Angular positions of the roll stands both for the assembly and securing of a Roll rings on the roller shaft as well as for the disassembly of the same Roller shaft with minimal downtimes of the rolling mill suitable is.
  • each piston have several evenly arranged over the pitch circle with a resilient force acted upon bolts are assigned, the associated with the inner piston Bolt axially on the one hand via a spring-elastic element in the piston and the other on the end face of the conical pin and the outer Piston-associated bolts are axially on the one hand via a spring-elastic element in the radial part of the base body and on the other hand on that of the rolling ring Support the face of the piston facing away.
  • each connector a releasable pressure line for a pressure medium is assigned.
  • the inner piston at least one, preferably several fuse elements are assigned, which in turn are in support the radial part of the body.
  • the invention provides that between the generation of the positive connection the clamping sleeve and the outer piston the opposite ends the same are each designed as a web and bayonet-like.
  • the cantilevered roller shaft 1 is provided with a conical pin 1a, which is followed by a free cylindrical head end 1b.
  • the rolling ring 3 is mounted on the pin 1a via a clamping sleeve 2.
  • the aim is for the roller ring 3 to rest against the shaft shoulder 1c via running disks 4 of a seal, which is also known and not shown, in order to ensure the exact position of the roller caliber relative to the rolling line.
  • the device according to the invention for assembling, securing and dismantling the rolling ring 3 consists of an axially fixable cylindrical base body 5 which can be slid onto the free cylindrical head end 1b of the roller shaft 1 and which is firmly connected via an associated radial part to a cylindrical pressure piece 6, which in turn is on the end face can be attached to the rolling ring 3.
  • the inner piston 7 can in turn be attached with its free end face to the end face of the clamping sleeve 2 facing it.
  • Each pressure chamber 9; 10 is also associated with an associated connector 9b or 10b for the releasable connection to a pressure line (hydraulic line), not shown, for a pressure medium, preferably pressure oil (Fig. 5 and 6).
  • the connection between the respective pressure chamber 9; 10 and associated connector 9b or 10b is realized by corresponding connecting holes 9c, 10c.
  • an anti-rotation lock is achieved between the base body 5 and the inner piston 7 or outer piston 8, which in turn is important for the locking of the clamping sleeve 2 with the outer piston 8 described below.
  • This locking is realized in such a way that the opposite ends of the clamping sleeve 2 and the outer piston 8 each have a web 2a or 8a, which in turn has a bayonet-like design and can accordingly be coupled to the counterpart.
  • each piston 7; 8 several evenly over the pitch circle arranged bolts 11 or 12 loaded with a spring elastic force assigned, wherein the pin 11 assigned to the inner piston 7 axially to one via a spring-elastic element 11a, which is known per se Coil spring can be in the piston 7 and the other on the end face of the Conical pin 1a and the associated with the outer piston 8
  • Bolt 12 axially on the one hand via a spring-elastic element 12a in the radial Part of the base body 5 and the other on the side facing away from the rolling ring 3 Support the end face of the piston 8.
  • the rolling ring 3 is to be clamped radially by means of a centering clamping sleeve 2. It is expedient to form-fit the device for mounting, securing and dismantling a rolling ring 3 with the conical clamping sleeve 2 and the rolling ring 3 placed thereon outside of the rolling line on a mounting surface in such a way that the bayonet-like web 8a of the outer piston 8 is connected to the web 2a of the clamping sleeve 2, which is also bayonet-like, and is locked accordingly.
  • the outer piston 8 is held by means of the associated spring-loaded bolt 12 in a position necessary for assembly.
  • the device according to the invention together with the assembled clamping sleeve 2 and the roller ring 3 attached, can be transported to the selected roller shaft 1 with the aid of suitable, suitable industrial trucks and / or a crane. Since the clamping sleeve 2 is provided with a locking ring 14, the rolling ring 3 is secured against sliding off the clamping sleeve 2 during transport or when installed in roll stands with any angular position of the roller shaft 1.
  • the axial depth of the recess is selected so that the clamping sleeve 2 together with the rolling ring 3 can be securely clamped.
  • a central nut 16 is screwed onto the threaded end of the free cylindrical head end 1b of the roller shaft 1 and tightened tightly, thereby axially fixing the roller ring 3 and the device on the roller shaft 1.
  • the securing elements 13 in the form of securing screws were screwed in advance from the radial part of the base body 5 so that the inner piston 7 does not touch the end face of the clamping sleeve 2 and between the pressure surfaces of the securing elements 13 and the side of the inner piston facing away from the clamping sleeve 2 7 there is a sufficient gap.
  • roller shaft 1 and the clamping sleeve 2 are to improve the Assembly and function of the device of the aforementioned additional Positive locking in the form of a splined connection 15 below the one formed Bayonets provided.
  • the connectors 9b and 10b Connect hydraulic lines.
  • the connector 9b is with pressure oil acted upon. This flows into the inner pressure chamber 9 and exercises over the inner one Piston 7 exerts a force on the adapter sleeve 2.
  • the dismantling of the rolling ring 3 is shown in FIGS. 3 and 4 and is necessary if the same is worn or if the desired caliber is changed.
  • the central nut 16 has been loosened, the securing elements 13 in the form of securing screws have to be unscrewed a suitable number of turns.
  • the hydraulic lines are in turn with the connectors 9b; 10b to connect.
  • the connector 10b and thus the outer pressure chamber 10 are pressurized with oil, the outer piston 8 experiences a force away from the rolling ring 3 and pulls the same from the conical pin 1a due to the bayonet connection with the clamping sleeve 2.
  • the pressing process is ended.
  • the complete device according to the invention including the clamping sleeve 2 and the rolling ring 3 can now be withdrawn from the roller shaft 1 and for example to the above Assembly area can be returned.
