Definitions

  • the invention relates to a method and a device for transversely rolling stepped hollow shafts or cylindrical hollow parts from a pipe.
  • pipe blanks for manufacturing divided and undivided pipe stabilisers for motor vehicles can be produced in an advantageous manner. They are characterised by virtue of the fact that they have variable diameters and wall thicknesses in regions over their longitudinal axis, which on the one hand leads to a reduction in component weight and on the other hand permits optimal usage of the installation space available. Furthermore, the load-adapted cross-sections permit a uniform tension distribution and thus optimal usage of the material used.
  • further advantages can be achieved by eliminating wall thickness fluctuations in the pipe used and by improving the material quality of the pipe surfaces by stretching any decarburization regions present and so-called “phosphate edges”.
  • the blank is axially compressed between wedge-shaped tools with inner forming tools at the same time during the rolling process and is rolled out starting from the centre to form a double-sided cup-shaped hollow body.
  • the outer contour of the inner forming tools corresponds to the inner contour of the hollow body.
  • the object is achieved in accordance with the invention by virtue of the fact that by means of rolling tools which can be radially advanced and are disposed in a planet-like manner around the workpiece the contour of the transition from a central diameter in one portion of the workpiece to the central diameter in an adjacent portion is rolled by means of co-ordinated control of radial advance of the rolling tools and axial feed of the workpiece and a mandrel head having an outer diameter which is adapted to the smallest inner diameter of the two portions is disposed underneath the rolling tools.
  • transitions can also be rolled without the assistance of a mandrel whose outer profile corresponds to the inner profile of the transition.
  • the outer periphery of the mandrel head does not lie against the inner periphery of the workpiece at the instantaneous forming site. Only towards the end of this transition and during rolling of continuous portions having a constant inner diameter does the mandrel perform its typical function. For this purpose, it is disposed underneath the rolling tools.
  • the friction between the workpiece and the mandrel head is restricted to a minimum. This is achieved on the one hand by a relatively short mandrel head and on the other hand by means of a clearance fit, which is typical for displacement, between the outer and inner diameters of the mandrel head and the workpiece. Moreover, in addition to this clearance a further clearance of at least 0.1 mm is preferably provided which promotes forming and is to be defined as flexing clearance.
  • the forming procedure is further assisted by virtue of the fact that the workpiece is mounted in support rollers.
  • three support rollers are disposed in each case in one plane in a planet-like manner around the workpiece and are mounted in a stand. They can be radially advanced onto the workpiece.
  • the stands are displaceable in parallel with the workpiece axis.
  • At least one stand is disposed in a stationary manner in proximity to the rolling tools. Particularly in the case of longer workpieces, at least one further stand is provided which preferably moves simultaneously with the workpiece end, to which it is allocated.
  • the support rollers serve to absorb the “transverse forces” which result from the forming procedure and which are not neutralised by the rolling tools and the active part of the rolling mandrel. Such remaining transverse forces also occur primarily during rolling of the transitions. Moreover, they support the weight of the workpiece parts which protrude over the active (engaged) part of the rolling mandrel.
  • FIG. 2 shows an enlarged section of FIG. 1
  • FIG. 3 shows the section “Z” of FIG. 2 .
  • FIGS. 4 a to 4 h show the stepwise formation of a pipe into a hollow shaft.
  • the device for transversely rolling stepped hollow shafts from a pipe as shown in FIG. 1 has an approximately cross-shaped outline in the plan view shown in FIG. 1 .
  • a rolling 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 rolling carriage 5 are disposed in parallel with the axis of the workpiece 1 (the pipe to be formed or the resulting hollow shaft) from right to left.
  • Rolling tools 3 are provided at the forming site. They are mounted in radial rolling carriages 2 . These rolling carriages can be displaced transversely with the respect to the workpiece 1 .
  • the rolling tools 3 are radially advanced therewith. For this purpose, they have a dedicated, preferably hydraulic, drive.
  • the rolling tools 3 are driven about axes in parallel with the workpiece axis by means of the rolling spindle drive 4 .
  • the clamping device 6 for clamping the workpiece 1 is located on the axial rolling carriage 5 .
  • the forces for pulling the workpiece 1 are applied against the rolling tools 3 by two hydraulic pistons which are disposed in a pivotable manner in the axial rolling carriage 5 .
  • FIGS. 4 a to 4 h illustrate the sequence of forming a hollow shaft which has multiple steps in its central part.
  • the workpiece 1 is clamped in the clamping device 6 and is pulled the distance of a feeding path s ax .
  • the rolling tools 3 are advanced radially by the distance s r .
  • the respective path length is indicated by the length of the arrow.
  • the direction is given by + and ⁇ .
  • + in the drawing denotes the movement to the left (in the direction of tension of the clamping device 6 ).
  • the radial advance of the rolling tools in the direction of the workpiece axis is denoted by +, and the opposite direction is denoted by ⁇ .
  • Rolling mandrels 8 a to 8 c which have an outer diameter corresponding to the respective smallest inner diameter of the workpiece are used. The mandrel head has not been illustrated.
  • FIG. 4 b a first transition from the previous diameter to a smaller central diameter is rolled.
  • the rolling tools 3 are advanced with +s r .
  • the workpiece 1 is pulled the distance of a small axial feed path.
  • the large diameter mandrel 8 a is disposed underneath the forming site. At the beginning of the transition, the inner periphery of the workpiece 1 is not yet supported by the mandrel 8 b.
  • steps 4 d and 4 e further step-formation similar to that performed in steps 4 b and 4 c is carried out but with the medium diameter rolling mandrel 8 b.
  • FIGS. 4 f and 4 g illustrate on the one hand a repetition of the above-described forming steps with the smallest diameter rolling mandrel 8 c .
  • a feature of FIG. 4 g is that a conical transition is rolled.
  • a small axial feed +s ax is coupled with a negative small advance ⁇ s r of the rolling tools.
  • the rolling mandrel is still located underneath the rolling tools 3 but at the instantaneous forming site is still only in radial proximity to the inner periphery of the workpiece 1 .
  • FIG. 4 h the hollow shaft is completely rolled.
  • the rolling tools are disengaged.
