Definitions

  • the invention relates to a cross rolling machine comprising two in a machine frame mounted, rotating in the same direction, jointly driven Rollers provided on their circumference with tool-forming work surfaces are.
  • Such a generic cross rolling machine on the elongated, constrictions or Collars and ridges such as cams or ribbed metallic workpieces are prepared, has become known from DE 43 01 314 C2.
  • the Roll stand or the machine frame has there two carriers, each with two support walls and in these trained bearings for waves.
  • Rollers On the waves Rollers are arranged, each carrier supporting a roller and at least a carrier by rotation about a common axis for changing the Rolling gap between the rollers relative to the other carrier is movable.
  • Carriers should also with a change in the roll gap, the axial direction the workpiece feed are symmetrical to the axes of the rollers (see DE 44 16 238 A1).
  • the invention is based on the object in a generic cross rolling machine To create a construction of the rolls without forming Disadvantages a simple and quick change of tools allowed.
  • the tool as Half shell formed and arranged on a tool carrier, with one continuous in the direction of the roll longitudinal axis and at its from the Tool side facing away open Anlagenaus founded on the tool axis aufstülpbar and connectable with this to a fixed roller unit. It leaves This ensures that the tool change neither opening the roll axis still a removal of a warehouse is necessary. Because after the release of connecting the tool carrier with a roller body, for example Fixing screws, the tool holder with the tool just after above, e.g. with the help of a hall crane, lifted off the roll axis become. When two with the rolls according to the invention having machine frame to a twin machine, i. arranged next to each other are, in the change position of the rollers each two tools simultaneously, i. from each machine frame a tool, with an interchangeable holder be dug.
  • a preferred embodiment of the invention provides that the Hopkinsausströmung has a polygonal cross-section and the roll axis with a complementary Square section is formed. After placing a tool carrier with its open at one end open on the square section and connecting the tool carrier with the roller main body to the fixed roller unit, is due to the angular joint connection with respect to the force absorption and transfer during forming optimized roller unit.
  • the invention provides in an advantageous embodiment that the roll axis below of the square section a mounting plate with a segment-like workpiece feed having.
  • a mounting plate with a segment-like workpiece feed having.
  • a roll 1 for a cross rolling machine 2 (see Fig. 3) consists of the Fig. 1st and 2 from a roll axis 3 and one placed thereon and with the roll axis associated tool carrier 4, which formed with a half shell 5 as Tool 6 is equipped, and one opposite the tool carrier 4 bolted to the roll axis 3 mounting plate 7, with a segment-like Workpiece 8 is provided.
  • the tool carrier 4 is provided with a extending in the direction of the roll longitudinal axis carrier recess. 9 (see Fig. 2) and the roll axis 3 with a complementary square section 10 trained.
  • the assembled state see Fig.
  • roller 1 is a compact, positively and non-positively connected roller unit before, in the with its open at one end lower end of the support recess 9 on the Square section 10 of the roll axis 3 inverted tool holder 4 via fastening screws 11 firmly connected to the mounting plate 7 and also over in the block of the square section 10 engaging screws 12 is screwed.
  • fastening screws 11 firmly connected to the mounting plate 7 and also over in the block of the square section 10 engaging screws 12 is screwed.
  • To change or replace the tool 6 need only the screws 11 and 12 to be solved, whereupon the entire tool carrier 4 just after lifted off or pulled up from the square section 10 of the roller shaft 3 can be (see Fig. 2), for example by means of a hall crane, including the Tool carrier 4 is provided with a hanger 13.
  • FIG. 3 The illustrated in Fig. 3 special version of a cross rolling machine 2 consists from two juxtaposed machine frame 2a, 2b, each with a pair of the rollers described above are equipped.
  • the rollers 1 are in the modular machine frame 2a, 2b stored, mechanically coupled together and from a common drive (gearbox / motor unit) 14 driven. After loosening the screws 11 and 12 (see. Fig. 2) can here each upwardly Asked tools 6 both machine frame 2a and 2b simultaneously with a changeover from the cross rolling machine 2 lifted and renewed or replaced.
