Definitions

  • the invention relates to a two-roll round machine according to the preamble of claim 1 and a Process for rounding sheets according to the preamble of Claim 9.
  • Two-roll round machines are known. at This is the sheet to be rounded between a round roller made of metal and a guide roller with pressure elastic Plastic coating, e.g. Neoprene®, passed, with the rollers pressed against each other be so that in the pressure-elastic coating forms an indented area in which a deformation of the sheet around the round roller.
  • pressure elastic Plastic coating e.g. Neoprene®
  • the invention is therefore based on the object an improved two-roll rounding machine create.
  • pressure-elastic rollers which in particular a Good rounding with a round roller stabilized against deflection results.
  • one or more Back-up rollers are provided, which in turn are the support pressure-elastic rollers, the support rollers in usually no rollers with pressure-elastic coating are (and are therefore referred to as rigid rollers can).
  • At least one Guide device is provided, which from the first Pair of rollers (guide roller, round roller) emerging sheet metal leads to the second pair of rollers (round roller, further roller).
  • the invention is also based on the object to create a rounding process, which the above Does not have disadvantages.
  • Figure 1 shows a first schematic Embodiment of a two-roll round machine 1.
  • This Machine has a machine frame shown only as box 2 on which the axes of the rollers and Rollers of the machine are stored, the schematic Representation of the axes perpendicular to the plane of the drawing shows.
  • In or on the machine frame is also only a Box 17 shown drive for the driven Rollers and an electronic control 16 provided which controls the drive.
  • This coating is a known plastic coating on such machines and will not be explained here. by virtue of this coating is followed by the roller 3 referred to as a pressure-elastic guide roller.
  • the roller is rotatably mounted about its axis 4 in the machine frame 2.
  • this roller does not have a pressure-elastic coating carries and therefore referred to below as a rigid roller becomes.
  • Figure 1 shows this roller spaced from the guide roller 3, so that the sheet 20 to be rounded can be inserted between the rollers.
  • Figure 2 wherein the same reference numerals as in Fig. 1 denote the same elements, shows the actual Round position, in which the round roller 6 against the guide roller 3 is pressed, so that the round roller 6 a Deepening in the pressure-elastic coating 5 of the Guide roller creates which presses the to be rounded Sheets on the round roller.
  • the sheet is on conventional Way rounded by the round roller 6 by the drive 17 is driven, which in Fig. 2 with arrows shown rotational movement of the rollers, and causes that the sheet 20 is drawn between the rollers 3 and 6 and is rounded around the roller 6.
  • Embodiment of the invention are now two more pressure-elastic rolls, also rolls with a plastic coating, which the Apply pressure-rigid round roller 6.
  • these two rollers 8 and 11 with their coatings 10 and 13 and the axes of rotation 9 and 12, which parallel to the axes of rotation 4 and 7 of the rollers 3 and 5 run laterally in the direction away from the guide roller 3 Area of the round roller 6 arranged.
  • the rollers 8 and 11 are arranged symmetrically to the plane E, which is spanned by axes 4 and 7.
  • the pressure elastic Rollers 8 and 11 each cause a new one Rounding the sheet 20 around the rigid roller 6.
  • these rollers support the Round roller 6, which is particularly low in the case of round rollers 6 Diameter, especially in the diameter range of 30 - 80 mm, is advantageous.
  • This can be an undesirable one Result in rounding or kinking of the sheet, which, however, follows when the sheet between the Rolls 8 and 6 passes and also between Rollers 11 and 6, through the appropriate forming again will be annulled.
  • a particularly good rounding results when the sheet 20 passes twice through the rollers mentioned runs through, i.e. after the first rounding process by means of the roller pairs 3 and 6, or 8 and 6 and 11 and 6 passed through the rollers 3 and 6 again and then again through the rollers 10 and 6 and 11 and 6. In this way, unrounded or improperly rounded sections safely avoided.
  • the Control 16 of the machine is designed accordingly, to cause each sheet to go through twice.
  • the round roller 6 is in turn spaced from the guide roller 3, as shown in Figure 1, and further also the rollers 8 and 11 spaced from the round roller 6, around the rounded plate perpendicular to the plane of the drawing can be removed from the round machine.
  • the Movement of the rollers 8 and 11 can be translational Movement down in the drawing, or one Pivotal movement of the axes of rotation 9 and 12 about a pivot axis each outwards so that the rollers 8 and 11 release the round roller 6.
  • the rollers 8 and 11 are then in the Figures 1 and 2 position shown spent.
  • continuous rollers 8 and 11 can also be spaced apart by a series of coaxial ones rollers arranged to each other.
  • a backup roller is also preferred 14 provided, which in turn the pressure-elastic rollers 8 and 11 supports.
  • the backup roller 14 is shown in FIG Example is rotatable about an axis of rotation 5 and is a pressure-rigid support roller, so it has no elastic Coating on.
  • FIG. 3 shows a further exemplary embodiment, the same reference numerals as used until now, designate the same elements. This is also done here the rounding of the sheet 20 between the pressure-elastic Guide roller 4 and the rigid roller 6. Below the same is now only a pressure-elastic roller 21 provided with their coating 23, which is about an axis 22 is arranged rotatably. Again, it can be natural are about multiple roles that together make up the roller form. Below this roller there is again a rigid pressure Support roller 24 mounted with its axis of rotation 25, which forms a support for the roller 21. This Roller 21 is used in the manner already described Rounding the sheet and supporting the round roller 6.
  • FIG. 4 shows a further exemplary embodiment, the same reference numerals the same elements describe.
  • a guide device 30 is also shown here, which is the rounded one emerging between rollers 3 and 6 Receives and guides sheet metal with its guide surface 31, such that the rounded sheet is in a suitable position is inserted between the rollers 8 and 6.
  • Through the Guide device 30 can surely emerge or buckling of the sheet 20 when it first comes into contact with the roller 8 can be prevented. In this case, in usually a single run through the sheet the roller pairs 3 and 6, or 8 and 6 and 11 and 6.
  • FIG. 5 shows a further exemplary embodiment, in which again the same reference numerals are the same Label elements.
  • This embodiment differs differs from that of FIGS. 1 and 2 or 4, in that, in addition to the rollers 8 and 13 common Back-up roller 14 also has its own back-up roller 32 for the roller 8 and 33 for the roller 11, respectively is.
  • the rollers 32 and 33 are each around Axes 34 or 35, rotatable.
  • the described insertion and unloading process applies as well as the corresponding drive and control and the construction of individual rolls from different coaxial Roles, as has already been described.
