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.
- Such a cross rolling machine on which elongated, constrictions or Metal workpieces with cuffs and elevations such as cams or ribs are made known by DE 43 01 314 C2.
- the roll stand or the machine frame there has two beams, each with two supporting walls and in these trained bearings for shafts.
- On the waves rollers are arranged, each carrier supporting one roller and at least one a carrier by rotating around a common axis to change the Roll gap between the rollers is movable relative to the other carrier.
- 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 in a generic cross rolling machine to create a construction of the rolls without forming Disadvantages allow easy and quick change of tools.
- the tool as Half-shell formed and arranged on a tool carrier which with one continuous in the direction of the longitudinal axis of the roller and at its from that Side of the carrier recess facing away from the tool on the tool axis can be slipped on and connected to a fixed roller unit. It leaves hereby achieve that neither an opening of the roller axis for the tool change it is still necessary to remove a bearing. Because after loosening connecting the tool carrier with a roller base body, for example The tool holder can easily be tightened using the tool above, e.g. with the help of an indoor crane, lifted off the roller axis become. If two with the machine frame having rollers according to the invention to a twin machine, i.e. arranged side by side two tools can be used in the changing position of the rollers at the same time, i.e. one tool from each machine frame with an interchangeable holder be excavated.
- a preferred embodiment of the invention provides that the carrier recess has a square cross section and the roller axis with a complementary Square section is formed. After attaching a tool holder with its downward open end on the square section and connecting the tool carrier with the roller base body to the fixed roller unit, is due to the angular joint connection with regard to the force absorption and transfer during forming optimized roller unit.
- the invention provides in an advantageous embodiment that the roller axis below of the square section a mounting plate with a segment-like workpiece feed having.
- a pair of rolls alternately always takes over the one roll Feeding the workpiece to be formed into the nip during each the rollers, together with their complementary tools, perform the forming make.
- a roll 1 for a cross-rolling machine 2 (see FIG. 3) is shown in FIG. 1 and 2 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. 2) and the roller axis 3 with a complementary square section 10 trained.
- the special embodiment of a cross-rolling machine 2 shown in FIG. 3 exists of two machine frames 2a, 2b arranged side by side, each with a pair of the rollers described above are equipped.
- the rollers 1 are in the machine frame 2a, 2b, which is made in modular construction, is mechanically supported coupled together and by a common drive (gearbox / motor unit) 14 driven. After loosening the screws 11 and 12 (cf. 2) the tools 6 of both machine frames, which are placed upwards, can be used here 2a and 2b simultaneously with an interchangeable holder from the cross-rolling machine 2 lifted and renewed or exchanged.
