Rib-On Project

Edificio IK4-AzterlanThe Rib-ON "Innovative Stamping Die for Aluminium Ribs Hot Stamping" project aims to develop and manufacture an innovative stamping die based on a modular/reconfigurable and low-cost approach to successfully produce different outer external wing rib models using new high performance aluminium alloys and tailored die steel and coating solutions. The die will serve to manufacture different shape/length aluminium ribs of FTB2 demonstrator ready to fly. 

Technological objectives

  • Definition and validation of the optimum hot stamping route of novel Al-Sc alloys based on trade off between performance (in terms of formability and mechanical properties) and manufacturing cost (in die heat treatments, reduced post-forming treatment, productivity, material usage, maintenance cost, energy cost,…).
  • Choose, among the options available in the market, the most favourable die steel-coating combination in terms of wear resistance performance, blank-die friction coefficient and aluminium build up avoidance
  • High Flexibility die based on modularity/reconfiguration: different shape configurations of the mould will be designed and implemented to manufacture both left and right hand side of FTB2 demonstrator and also implementing the option of different size ribs

The following quantifiable objectives will be demonstrated at BATZ and Topic Manager’s facilities when applicable:

  • Uniform thickness and properties all along the wing ribs ensuring: tight tolerances up to ±0.4 in volume; tight tolerances up to ±0.3 in  trimming; batch to batch deviation in yield strength lower than 5 %.
  • Monitor the performance of the die: Key process variable monitoring such as lubrication, punch force draw-in and speed, flow and temperature the cooling fluid of die, part and die temperature, time of transference from the furnace to the die, time of quenching, blank positioning… both by sensoring and trained inspection procedures. Dimensional control measurements and thermography imaging of the stamped wing ribs will be used to monitor the health of the die.
  • Batz S. Coop. (coordinator): BATZ is one of the leading stamping die suppliers worldwide in the automotive sector. Additionally, BATZ’s AEROSPACE DIVISION supplied nowadays several components for main aeronautic companies with technology exclusively provided by its own R&D department.
  • IK4-Azterlan Metallurgy Research Centre: Its knowledge covers die performance (cooling strategy, wear resistance, novel manufacturing strategies), hot stamping furnace design (thermal profile and conveyor system) and hot stamped products (process window definition, in die quenching optimization, protective coatings…). Extensive experience in the development and validation of novel heat treatment and processing route of new aluminium alloys.

This project has received funding from the Clean Sky 2 Joint Undertaking under the European Union’s Horizon 2020 research and innovation programme under grant agreement No 755493.
