Definitions

  • the object of the present invention is therefore to provide a forming machine which can be used for the relatively rapid deformation of thick workpieces into correspondingly thick-walled cylindrical hollow bodies of great precision with small to large diameters and also of great length, not for each dimension of the starting material and Other tools are needed.
  • “Relatively quickly” here means less than 5 minutes to produce a hollow cylindrical body of 10 to 15 m in length and up to a wall thickness of 35 mm.
  • Such a forming machine has an upper roller and two lower rollers, all of which have a drive element at at least one end, and is characterized in that it is distributed uniformly over the roller length
  • Arranged C-shaped stands are provided with one pair of support rollers per roller, the pairs associated with the adjustable rollers being provided with means for moving them in a plane perpendicular to the roller axes.
  • All the rollers are expediently provided with electric or hydraulic motors at both ends, one of the two motors serving to drive the top roller being able to be uncoupled from the roller end and pivoted away.
  • the rollers themselves can be connected in some way to the corresponding ends of the C-shaped stands: it is possible, for example, to provide the top roller with a groove for each stand and to accommodate a band in each groove, the ends of which at the C -Stand is hung up, so as to hang up the roller.
  • the lower rollers can rest on the support rollers and can be secured by additional guide means if necessary.
  • FIG. 1 shows a highly schematic, perspective illustration of a forming machine according to the invention, in which the organs serving to drive the drive are completely omitted at the closer roller ends and are only indicated with a box at the other roller ends
  • 2 shows a section through a C-shaped stand
  • Figures 3 to 6 the operation of the forming machine in the manufacture of a cylindrical hollow body
  • 7 shows the principle diagram of a forming system with two forming machines.
  • the forming machine shown in FIG. 1 has four C-shaped stands, designated 1 to 4 as a whole in the drawing, each formed from two vertical plates A and B, all of which stand on two supports, designated 8 or 9, or on a base and are connected to each other by a shield 10 and a frame part 11. To increase the rigidity, it is of course readily possible to connect the plates of a stand and the stands standing next to one another by means of further connecting elements.
  • a stub shaft 30 is mounted in the two plates A and B of each C-stand, which is provided with an eccentric disc 31 and a lever arm 32.
  • the free end of the lever arm 32 is connected in an articulated manner to the piston rod 33 of the hydraulic cylinder 34, so that the lever 32 and with it the eccentric disc 31 are rotated by the displacement of the piston rod in the cylinder.
  • the support plate 23 lying on it is displaced upwards or downwards and also somewhat laterally.
  • a block 22 is horizontally displaceably mounted, which can be displaced horizontally by the eccentric 36 seated on the shaft 35, the rotating or adjusting mechanism for the shaft 35 mounted in the two plates A and B being shown here purely schematically and with 37 and the connection plate provided with the bore for the eccentric 36 is designated 38.
  • the piston 40 of a hydraulic cylinder 41 is supported, which, depending on the loading with the hydraulic fluid, can move up and down on the inclined sliding surface D.
  • guide shoes can serve both for this roller and for the two other rollers, or metal strips which are guided in a groove of the roller and whose two ends are fastened to the carrier 19 or 16.
  • a carrier 12 is attached, in which the two support rollers 13 and 14 are freely rotatable. These support rollers 13 and 14 serve to support the upper roller 15, which is suspended here on the carrier 12 or on the shield 10 by means of bands not shown in the drawing and guided in the grooves 15b of this upper roller 15.
  • All three rollers i.e. the upper roller 15 and the lower rollers 24 and 42, of which the latter is the bending roller, are each provided with a drive at their two ends, expediently a hydraulic or electric motor, one of the two being used to drive the Upper roller 15 serving motors can be detached from the roller and is mounted in such a way that it can be pivoted away from the roller as is known in other, that is to say conventional three or four-roller machines, in which one is formed into a hollow cylinder Workpiece can be extended laterally.
  • FIG. 3 shows that when the workpiece, that is the sheet-metal plate 43, is inserted between the upper roller 15 and the lower roller 24, the two lower rollers, that is to say the actual lower roller 24 and the bending roller 42, are at the same height, so that the workpiece 43 is comfortably horizontal can be introduced.
  • the axis 24a of the lower roller 24 is offset to the left by the distance X relative to the axis 15a of the upper roller 15, as has already been shown in FIG.
  • the bending roller 42 is raised in that the hydraulic fluid flowing in pushes the cylinder 41 upwards on the sliding surface D until it has assumed the position shown in FIG. The entire three-roll mill is then put into operation, so that the workpiece 43 is bent as shown in FIG.
  • the main advantage that can be achieved with the above machine is that, as it were, sheets of any thickness and very long can be given a hollow cylindrical shape, since the C-shaped stands, which in themselves can be present in any number and of which each is provided with a pair of support rollers for each shaft, which absorb the bending forces and thereby prevent the dreaded bending of the rollers, which is feared in ordinary three- or four-roll bending machines and is difficult to control.
  • the size of the distance from the C-stand to the C-stand depends on the size of the load for which the forming machine is designed. For example, a distance of 80-150 cm, ie approximately 120 cm, from the center of the stand to the center of the stand may be appropriate.
  • top roller which can usually be used for a top roller with a smaller diameter and to replace the entire shield 10 with the support 12 and the support rollers 13 and 14 carried in it, which then proportionate can be easily carried out if there are aids for the power transmission from the plate to the plates A and B of each C-stand, such as the webs marked 7 in the drawing and the plate itself with simple fastening means that do not serve to transmit the force, e.g. with some screws , is secured against unintentional detachment from the C-stands.
  • the workpiece Due to the fact that the workpiece is rolled round in a uniform operation, it is treated very gently, which is particularly important for steels of high purity, where pre- or reworking of the edges by rollers results in additional strengthening and thus a deterioration in quality Has.
  • this device it is also possible with this device to install an automatic readjustment which contains the element measuring the curvature of the workpiece and a computer controlled by it, which in turn controls the displacement of the lower roller 24 and the bending roller 42.
  • FIG. 7 where they form a tube production system together with a stitching system.
  • the two forming machines are labeled 50 and 51.
  • the forming machine 50 is fed the rectangularly cut sheet metal plates 52 by the conveyor device 53, and first in the longitudinal direction L of the system and then in the transverse direction Q perpendicular thereto.
  • the plate 52 is deformed in the manner described above with reference to FIGS. 3 and 4.
  • the half-machined workpiece 52 is moved out of the forming machine 50 to the right using aids known per se in the manner already described above and then by means of a cross conveyor, which is indicated in FIG.
  • the second forming machine 51 fed. While the first forming machine 50 is set up in such a way that the opening of the C-stands is directed towards the conveyor 53, the forming machine 51 is set up in mirror image, that is, in such a way that the opening of its C-stands is directed against the cross conveyor 54. As a result, the space-consuming turning of the workpiece 52 can be dispensed with and this can be fed to the forming machine 51 in the manner in which it is moved out of the forming machine 50. In the forming machine 51, the second part of the shaping now takes place as described above with reference to FIGS. 5 and 6, with FIGS.
  • the entire system can work every two to three minutes, i.e. the system, which contains two forming machines, delivers a cylindrical tube every 2 to 3 minutes.
