Presentation Transcript

  1. Axial Forming Process 2 • forming cylinder with concentric mandrel device • 2 segment chuck • 3 forming die • 4 mandrel • 5 workpiece 1 3 5 4 3 1

  2. Axial Forming Forming an external spline on a tube

  3. Axial Forming Forming an internal spline inside a tube

  4. Axial Forming FEM stress analysis: red: tension blue: pressure

  5. Axial Forming Examples of applications: Expanding Reducing Profile forming

  6. Axial Forming Examples of applications: Spline forming (internal and external) Upsetting Flanging

  7. Axial Forming Highlights: • tight tolerances – very small pitch errors axial forming of splines possible also on thin walled tubular components • excellent surface quality, little roughness • block teeth and missing teeth possible • short cycle times (for example 5 seconds) • low tooling costs / high tooling performance (approx. 50.000 pcs. and greater) • cold formed part / possibility of taking advantage of hardness increase • homogenous internal stress distribution / little deformation during heat treatment

  8. Axial Forming Examples of applications: shafts with involute splines

  9. Axial Forming Examples of applications: shafts with involute splines

  10. Axial Forming Examples of application: shafts with involute splines

  11. Axial Forming Examples of applications: involute splines used as linear guiding

  12. Axial Forming Examples of applications: expanding and reducing

  13. Axial Forming Examples of applications: reducing of ends of propeller shafts Reduced length approx. 200mm

  14. Axial Forming • Range of machines: • Forming force: up to 1000 kN • Diameters: up to 200 mm • Forming stroke: up to 1000 mm • Forming speed: up to 50 mm/s • Power: up to 100 kW Base machine withoud feeding or handling device

  15. Axial Forming Automatic Transfer line: This modular design allows interlinking of multiple machines generating a linear transfer line. This kind of machine enables combined integration of several different manufacturing processes.

  16. Axial Forming Cycle time: High speed forming machine for steering components. Cycle time: 6 seconds!

  17. Axial Forming Multiple die slide: Allows multiple consecutive operations without unclamping the workpiece
