Definitions

  • the invention relates to a leveler for straightening metallic bands according to the preamble of claim 1 (see, for example US 5 255 548 A ).
  • a straightening machine of the present type accordingly comprises a number of leveling rolls, a drive for the straightening rolls and a main gearbox arranged between the drive and the straightening rolls.
  • the straightening rollers are arranged in a removable cassette and connected via cardan shafts and releasable couplings with the main transmission.
  • WO 2005 / 080016A discloses a straightening machine which is considered to be state of the art according to Art. 54 (3) EPC.
  • the range of the straightening strip thickness is between about 1.5 mm and 5 mm.
  • Desirability is often desired from a range of tape thicknesses between 0.8 mm and 15 mm, which, however, can not then be processed with a single fixed diameter of straightening rollers.
  • a straightening machine has been proposed with a number of driven straightening rollers, which are detachably connected via drive shafts with a main gear.
  • the straightening rollers can be removed together with their storage on a roller table from the straightening machine, so that they can be replaced with a new set straightening rollers.
  • the number of clutches or outlets of the main gear is naturally measured by the number of straightening rollers with the largest possible diameter in the present straightening machine. In this respect, it is not possible to operate a higher number of straightening rollers with a smaller diameter, although the space would be there for it. Instead, then in particular the outer propeller shafts, which connect the outer (small) straightening rollers with the outer outlets of the main gear, strongly angled, since the distance between the individual straightening rollers with each other must be very small and therefore the dimensions of a removable cassette with straightening rollers of small diameter compared to Dimensions of the main gear is unfavorably much smaller.
  • the present invention is therefore an object of the invention to improve a straightening machine of the type mentioned in terms of their applicability to the widest possible spectrum of strip thicknesses or leveling diameters.
  • the invention is first characterized by the fact that between the main gear and the straightening rollers, an additional transfer case with one outlet for each straightening roller is arranged.
  • the transfer case is thus connected between the main gear and the straightening rollers and allows for a, to arrange a higher number of straightening rollers of smaller diameter in the straightening machine, as outlets on the main gearbox are available.
  • the transfer case is suitably adapted to the dimensions of the straightening rollers used at the outlets, while the connection between the main gearbox and the transfer case can optionally take place with a single shaft or a single coupling piece, so that even with very small straightening diameters and a main gear, the large straightening roll diameter is adjusted, no adverse bending of the cardan shafts must be made.
  • the transfer case according to the invention increases the range of directional roll diameters and the corresponding straightening roll number, so that ultimately the range of sheet thicknesses that can be addressed with a single straightening machine, advantageously increased. It is of course possible to use several different transfer case or cascaded two or more transfer case in a row to further increase the range of workable strip thicknesses.
  • the transfer case is associated with the interchangeable cassette with the straightening rollers and integrated into this removable cassette, so that those removable cassettes with straightening rollers, which have a small diameter, can be used with the appropriate transfer case in the straightening machine.
  • the transfer case is not only connected via a clutch to the main transmission, but over two, three or more couplings.
  • the straightening rollers are connected via drive shafts with the outlets of the transfer case, and on the drive side when between the transfer case and main gearbox no more cardan shaft is used, but solid couplings.
  • Figure 1 shows an embodiment of a straightening machine, wherein a total of 13 straightening rollers 1, of which only the upper seven can be seen in the plan view, are indicated in the present illustration.
  • Each of the straightening rollers 1 is connected via a respective propeller shaft 2 and a coupling piece 3, each with an outlet 4 of a main transmission 5.
  • the straightening machine is driven by a drive 6.
  • the straightening rollers 1 and the propeller shafts 2 sit on an exchangeable cartridge 7, which is removed by axially moving away and thereby loosening the coupling pieces 3 from the straightening machine and against another exchangeable cartridge 7 'with straightening rollers 1' of smaller diameter can be exchanged.
  • the interchangeable cassette 7 shown in Figure 1 and Figure 2 includes leveling rolls 1 with a diameter of 150 mm. At this leveling diameter, which is the largest to be installed in the present straightening diameter, the main gear 5 is adjusted with its outlets 4. Accordingly, a total of 13 outlets 4 are present and spaced apart so that the propeller shafts 2 are angled at advantageously small angles.
  • FIGS. 3 and 4 the same straightening machine is shown with another exchangeable cassette 7 '.
  • the drive 6 and the main transmission 5 with its 13 outlets 4 has remained identical; only the removable cassette 7 has been replaced by a removable cassette 7 'with straightening rollers 1' of smaller diameter.
  • the transfer case 8 is, as Figure 4 shows particularly clearly in the removable cassette 7 'integrated and is coupled with this at the outlets 4 of the main transmission 5.
  • three coupling pieces 3 are provided in order to obtain a more even distribution of the power flow in the transfer case 8 and the transfer case 8 accordingly not to have to dimension too massive.
  • FIG. 3 illustrates, it is possible with the invention to increase the 13 outlets 4 of the main transmission 5 to 21 outlets 9 here in order to be able to operate 21 straightening rollers 1 'of smaller diameter, which are additionally acted upon by drive shafts 2' with torque, which are operated at an optimum angle.
  • 21 straightening rollers 1 'of smaller diameter which are additionally acted upon by drive shafts 2' with torque, which are operated at an optimum angle.
