Definitions

  • the invention relates to a method and an apparatus for the transverse rolling of stepped hollow shafts or cylindrical hollow parts from a tube.
  • tube preforms for the production of split and undivided tube stabilizers for motor vehicles can be produced in an advantageous manner. These are characterized in that they have over their longitudinal axis partially variable diameter and wall thickness, which on the one hand leads to a reduction in the weight of the component and on the other hand allows the optimal use of the available space.
  • the load-adapted cross-sections allow a uniform distribution of stress and thus optimum utilization of the material used.
  • other advantages can be achieved by eliminating wall thickness variations of the pipe used and by improving the material quality of the pipe surfaces by stretching any decarburization areas and so-called "phosphate spaces".
  • the blank is axially compressed during the rolling process between wedge-shaped tools simultaneously with internal dies and rolled out from the middle to a double-sided cup-shaped hollow body.
  • the outer contour of the inner molds corresponds to the inner contour of the hollow body.
  • the swaging can be used. However, it is not very productive despite high mechanical complexity.
  • the object of the invention is to provide a solution with which with a few simple tools stepped hollow shafts or cylindrical hollow parts of various dimensions and also larger lengths can be flexibly rolled from a tube.
  • the object is achieved in that with radially deliverable, planetary arranged around the workpiece rolling tools, the contour of the transition from a mean diameter in a section of the workpiece to the mean diameter in an adjacent section by means of coordinated control of radial feed of the rolling tools and axial Rolled feed of the workpiece and a mandrel head is arranged with a matched to the smallest inner diameter of the two sections outer diameter of the rolling tools.
  • a further game in the size of at least 0.1 mm is preferably provided that promotes the transformation and should be referred to with Walk game.
  • the deformation is further supported by the fact that the workpiece is mounted in support rollers.
  • three support rollers are arranged in a plane like a planet around the workpiece and stored in a block. They are radially deliverable to the workpiece.
  • the blocks are displaceable parallel to the workpiece axis.
  • At least one block is arranged stationary in the vicinity of the rolling tools.
  • at least one further block is provided, which preferably moves with the workpiece end, which he is associated with moves.
  • rolling tools having a smoothing and a forming shoulder, reshaped, wherein preferably the free edge of the smoothing shoulder, with a radius of 0.5 to 3 mm is rounded. With this edge especially the short transitions are rolled.
  • the workpiece is preferably turned.
  • Sections with thicker walls and heavier materials are heated prior to rolling.
  • the device for cross rolling stepped hollow shafts from a tube to Fig. 1 has in the plan view according to Fig. 1 a roughly cross-shaped floor plan. Parallel to the axis of the workpiece 1 (the tube to be formed or the resulting hollow shaft) are from the right to the left a roller spindle drive 4, a rolling mandrel bearing 7, a rolling mandrel 8, the workpiece 1, support rollers 9, a clamping device 6 and an axial roller carriage 5 are arranged.
  • rolling tools 3 are provided. They are mounted in radial rolling carriage 2. These rolling carriages are displaceable transversely to the workpiece 1. With them, the rolling tools 3 are delivered radially. You have this own, preferably hydraulic drive.
  • the drive of the rolling tools 3 about axes parallel to the workpiece axis is carried out by the roller spindle drive 4.
  • the workpiece 1 is pulled during forming with the axial roller carriage 5 to the left and rotated simultaneously with the rolling tools 3.
  • the clamping device 6 for clamping the workpiece 1 is located on the axial roller carriage 5.
  • the forces for pulling the workpiece 1 are applied with two hydraulic pistons, which are arranged pivotably in the axial roller carriage 5, against the rolling tools 3.
  • a slide guide 11 is disposed below the workpiece 1.
  • On her bucks 12 are arranged displaceably 9, each with three support rollers.
  • the support rollers 9 surround the workpiece 1 like a planet and are radially deliverable to the respective outer diameter of the workpiece 1.
  • the block 12a in the immediate vicinity of the rolling tools 3 is stationary.
  • the blocks 12b, which are further away from the rolling tools 3, run along with the workpiece 1 (see double arrow under the blocks 12b). Their distance from the rolling tools 3 changes continuously with the forming.
  • the direction of movement of the workpiece 1 is shown on the left side with an arrow.
  • the free edge of the smoothing shoulder of the rolling tool 3 is rounded with a radius r.
  • FIGS. 4a to 4h shows the forming sequence of a multi-stepped hollow shaft in the middle part.
  • the workpiece 1 is respectively clamped in the clamping device 6 and is pulled by a feed path s ax .
  • the rolling tools 3 are delivered radially around S r .
  • the respective path length is indicated by the length of the arrow.
  • the direction is indicated by + and -.
  • axial feed + means in the drawing, the movement to the left (in the pulling direction of the tensioning device 6).
  • the radial feed of the rolling tools towards the workpiece axis is marked with +, the opposite with -.
  • Rolling mandrels 8a to 8c having an outer diameter corresponding to the respective smallest inner diameter of the workpiece are used. On the representation of the thorn head was waived.
  • Fig. 4a the workpiece is still the original tube. It is already clamped. Rolling tools 3 and mandrels are not engaged.
  • a first transition from the previous to a smaller average diameter is rolled.
  • the rolling tools 3 are delivered with + s r .
  • the workpiece 1 is pulled by a small axial feed path.
  • the diameter-sized mandrel 8a is arranged below the deformation point. At the beginning of the transition, the inner jacket of the workpiece 1 is not yet supported by the mandrel 8b.
  • steps 4d and 4e (cf. Fig. 4d and 4e ) takes place a further gradation analogous to the steps 4b and 4c, but with the diameter in the middle rolling mandrel 8b.
  • FIGS. 4f and 4g represent, on the one hand, a repetition of the already described forming steps with the smallest rolling mandrel 8c in diameter.
  • a special feature of Fig. 4g rolled a tapered transition.
  • a small axial feed + S ax is coupled with a negative small delivery -S r of the rolling tools.
  • the rolling mandrel is still under the rolling tools 3, but in the current forming only in the radial vicinity of the inner shell of the workpiece. 1
  • a hollow shaft was rolled from an approximately 1.5 m long tube of 34MnB5 with an outer diameter of about 25 mm and a wall thickness of about 4 mm.
  • the tube was stepped by about 2 mm in outside diameter.
  • the wall thickness of the stepped parts was reduced by approx. 1 mm.
  • the forming sections were heated.
  • the mean rolling temperature was 600 ° C.
