Definitions

  • the invention relates to a guide assembly in a plant for deforming a workpiece, and particularly to a guide assembly forming part of a metal-rolling mill, especially a strip mill.
  • the guide assembly serves to guide strip ov various strip materials, particularly metal of various compositions, temperatures, widths and thicknesses.
  • Straight edge guides used in guide assemblies of rolling mills in particular to edge guides of milled or split strip are described for instance in DE 14 27 923 A. This state of the art deals with the wear of straight edge guides when guiding strip in particular.
  • EP 0 721 812 A1 [U.S. Pat. No. 5,687,603] describes the guides at side edges of the band for the same purpose, the edge guides consisting of a number of subdivided segments both near the rolls as well as between them. Moreover, these individual segments or segment pairs can be moved individually and independently of the adjacent segments on the strip toward it or away from it to control the wear of the strip and of the lateral guide.
  • GB 2,031,771 A in turn describes a guide assembly for a rolling train provided between at least two adjacent roll stands along a roller conveyor.
  • the objective of the assembly as well as of the strips used is to limit wear of the strip guides to a minimum, and at the same time to minimize damage to the guided strip edges.
  • actuators In practice, a number of different actuators are known to adjust or press the straight edge guides against the respective strip edges.
  • Mechanical actuators frequently include rack-and-pinion arrangements, nuts running on threaded rods, sprocket wheel chain threaded rods nut actuators or external fluid actuators.
  • the fluid actuators are in turn generally hydraulic.
  • the invention relates to guide assemblies of the type described above as used for instance in strip-rolling mils at the intake side and/or the output side of roll stands such as for example Steckel rolling mills, reversing roll stands of cold-rolling mills, or at the intake and/or output side of roll stands that are arranged in tandem, and particularly upstream or downstream of coilers.
  • the invention can be applied to form all conceivable types of strip, particularly to metal rolling mills or plastic deformation trains. It is preferred particularly that the guide assembly according to the invention be at the upstream or downstream side of at least one roll stand of a finishing rolling train or of a so-called finish rolling mill.
  • Guides that are positionable and preferably parallel to each other are provided in the guide assembly in accordance with the invention that can center or align the strip being worked in the working device and particularly between the forming arrangements, such as for example the roll stands. At least one guide will be acted on by at least one actuator to ensure a wide field of application of the guide assemblies for diverse strip profiles or dimensions. In the event that only one guide's position can be changed or pressurized, the actuator also effects a positioning to the opposing guide via the pressurized guide and via the guided strip itself.
  • each guide has its own actuator.
  • the actuator must be provided in such manner that pistons shiftable in a cylinder are attached to a straight edge guide.
  • the cylinder for the piston in turn is formed in a guide beam and integrated into it.
  • the guide beam not only assumes the function of the guide itself but also the function of a cylinder for the piston attached to the guide.
  • any movement of the piston in the cylinder integrated into the guide beam effects a direct and contemporaneous equal movement of the guide along the guide beam. This therefore ensures a safe and undelayed positioning of the guide or guides relative to the longitudinal edges of the strip being worked.
  • the integration of the cylinder in the guide beam of the actuator only has a minimal number of spaces where aggressive media, particulate matter, etc. could get caught or collect.
  • the occurrence of so-called “drawer effects” where foreign matter, which collected in a large hollow space or cavity that could lead to a blockage of the arrangement particularly in the event of a reduced volume of the space or cavity can be reduced. This allows wear of the individual components of the actuator and of the guide assembly to be reduced altogether to a minimum.
  • two guides opposite to each other are connected with each other via a common guide beam.
  • this common guide beam can extend between and below the conveyor rolls of a roller conveyor and accordingly below the strip being worked or the strip to be formed.
  • the guide beam be essentially symmetrical and that in both ends of the guide beams, preferably the outer ends, respective cylinders be formed in such a way that a piston that is attached to a respective one of the edge guides can shift.
  • This will advantageously reduce the number of parts used in the guide assembly and also increase the stability of the guide assembly as a whole.
  • this ensures that two guides that are opposite of each other can be moved in a synchronized manner along the same displacement path toward each other or away from each other. This in particular supports in an advantageous manner centering the material or strip travel within the forming device.
  • the shape of the guide beam is not limited any further.
  • the guide beam basically be cylindrical and it is especially preferred that the cylindrical form basically have a circular profile extending perpendicular to the guide beam's longitudinal direction.
  • the cylindrical form of a guide rail is less susceptible to particulate matter adhering to it and moreover, it can be cleaned using comparatively simple means. All this supports the resistance to the wear of the guide assembly and an extension of the maintenance and/or exchange intervals of the actuators.
  • the number of actuators that are connected to each guide is not limited in accordance with the invention. However, it is preferred that two actuators be attached to one guide, preferably that two actuators be connected to the two guides of the guide assembly. This ensures a particularly safe guidance through the guide assembly of the strip being worked or of the material that is to be formed. In addition, it allows the guides to remain essentially undeformed by the strips' longitudinal edges at comparatively high pressures.
  • the coupling of the respective actuators to each other is preferred in order to prevent any misadjustments of the respective guides due to the positions of the ends of a guide with respect to the longitudinal strip edges.
  • a coupling it is preferred that it be realized mechanically, particularly by providing at least one rack-and-pinion arrangement that positions the guides preferably in a synchronized manner.
  • a modular assembly of the actuators is preferred where a guide beam, a guide and at least one piston are assembled that can be installed and/or removed as a unit.
  • such a modular assembly allows the continued use of a control unit or controller that is adjusted to the type of module and/or preadjusted hydraulic systems.
  • the actuator of the guide assembly according to the invention has a cover, and preferably a common cover.
  • a cover should extend over the entire module mentioned above in order to reduce its total wear to a minimum.
  • the guides be positionable independently from each other. This allows a specially safe process at both sides of the strip. Particularly when rolling so called continuous custom blanks having various thicknesses across the width of the strip, exercising a low pressure upon the comparatively thin strip side can avoid strip-edge damage at both sides compared to pressurizing the comparatively thick strip side.
  • control units or controllers be attached to at least one actuator of the guide assembly according to the invention.
  • actuators it is particularly preferred that they can be controlled or regulated independently of each other. In a particularly preferred manner this provides maximum flexibility of the process in a forming plant having a product variety that is as comprehensive as possible.
  • the invention is particularly suitable for use in metal-rolling mills, preferably strip-rolling mills.
  • the guide assembly in accordance of the invention be at the intake side of at least one roll stand of a finishing rolling train.
  • the guide assembly in accordance with the invention be arranged at the output side of at least one roll stand of a Steckel train.
  • FIG. 1 is a partly sectional and schematic top view of an embodiment of a guide assembly according to the invention.
  • FIG. 2 is a schematic cross-sectional diagram along line A-A of FIG. 1 .
  • FIG. 1 is the partly sectional schematic top view of a guide assembly according to the invention for guiding strip 1 .
  • guides 3 a and 3 b are provided that can be positioned by respective actuators 4 a, 4 b against the strip 1 .
  • the guides 3 a, 3 b are both of the same cup shape with end flanges that can press against the respective longitudinal edges of the strip 1 .
  • both guides 3 a, 3 b are carried on a common guide beam 9 that is shown here in a bottom view of the guide assembly, so that it extends below the strip 1 moving past the guides 3 a, 3 b.
  • Identically dimensioned cylinders 7 a, 7 b are formed in outer ends of guide beam 9 , forming parts of respective double-acting actuators 4 a, 4 b. Respective pistons 6 a, 6 b can be shifted hydraulically in the cylinders 7 a, 7 b so that they form piston/cylinder arrangements 6 a, 7 a, and 6 b, 7 b operated by a control or stop unit (not shown).
  • the outer ends of the pistons 6 a, 6 b engaged in the cylinders 7 a, 7 b are fixedly connected to the floors of the respective cup-shaped guides 3 a, 3 b so that displacement of the pistons 6 a, 6 b in the respective cylinders 7 a, 7 b will also displace of the respective guides 3 a, 3 b along their displacement path defined by the guide beam 9 .
  • FIG. 2 shows a section of a partly shown actuator along section line A-A of FIG. 1 .
  • the guide beam 9 is formed as a cylinder of circular cross section perpendicular to its longitudinal direction.
  • the cup-shaped guide 3 a also is essentially of cylindrical shape in the outer region.
  • a chamber is thus formed in each outer end of the guide beam 9 that serves as a cylinder 7 for a piston 6 that is slidable therein.
  • the piston 6 in turn is fixedly connected to the floor of the respective cup-shaped guide 3 a and travel of the piston 6 within the cylinder 7 is limited by the end wall 9 a of the cylinder 7 in the guide beam 9 as well as by stop ring 9 b as outer abutment of the piston/cylinder arrangement 6 , 7 .
  • An additional anti-twist protector 10 extending longitudinally along the guide beam 9 inside the guide 3 a safely prevents rotation of the guide 3 a around the cylindrical guide beam 9 .
