Definitions

  • the invention relates to a cross rolling machine comprising two in a machine frame mounted, rotating in the same direction of rotation, jointly driven Rollers that provide work surfaces forming tools on their circumference are.
  • Beams should change the axial direction even if the roll gap changes the workpiece feed run symmetrically to the axes of the rollers (see DE 44 16 238 A1).
  • the invention has for its object a generic cross rolling machine to create, with the cycle times without the disadvantages mentioned significantly increase.
  • this object is achieved in an incredibly simple manner by that the roller pairs of two modular machine frames mechanically coupled and by a common drive are driven.
  • two identical, parallel arranged side by side Machines are operated in twin construction, which is due to the mechanical Coupling only a motor and gear unit is required, let double the number of pieces per revolution. This requires there is no independent control and loading and unloading of the two machine units with the workpieces to be formed or finished.
  • a preferred embodiment of the invention provides that the rollers such Have diameter that only when forming a workpiece half the circumference of a pair of rollers required, the tools half-shell trained and on the rollers of the roller pairs of each machine frame are arranged offset by 180 °.
  • the rollers such Have diameter that only when forming a workpiece half the circumference of a pair of rollers required, the tools half-shell trained and on the rollers of the roller pairs of each machine frame are arranged offset by 180 °.
  • a cross-rolling machine 2 designed in a twin construction consists of two in parallel machine frames 2a and 2b arranged side by side, in each of which a pair of rollers from adjacent rollers 1 is stored.
  • the rollers 1 of the first machine frames 2a are interposed by a motor 14
  • Rollers 1 worn tools 6 of the pair of rollers of the machine frame 2a are compared to the tools 6 of the rollers 1 of the machine frame 2b offset by 180 °.
  • Each tool 6 extends over half the circumference of a roller 1 or the rollers of a pair of rollers, wherein the diameter of the rollers 1 are dimensioned such that the forming of one is not shown, by means of a workpiece feed 8 in the roll gap of a pair of rolls only half the circumference of a roller 1 or a pair of rollers required.
  • a roll 1 for a cross-rolling machine 2 (see FIG. 1) is shown in FIG. 2 and 3 from a roller axis 3 and one placed thereon and with the roller axis connected tool carrier 4, which is designed as a half-shell 5 Tool 6 is loaded, and one opposite the tool carrier 4 screwed onto the roller axis 3 mounting plate 7, which with a segment-like Workpiece feed 8 is provided.
  • the tool carrier 4 is with a carrier recess 9 extending in the direction of the roll longitudinal axis (see FIG. 3) and the roller axis 3 with a complementary square section 10 trained.
  • twin cross rolling machine 2 shown in Fig. 1 can after Loosen the screws 11 and 12 (cf. FIG. 3), each placed upwards Tools 6 of the rollers 1 of both machine frames 2a and 2b simultaneously with an interchangeable holder lifted from the cross-rolling machine 2 and replaced or be replaced.
