Abstract The article presents a properly planned and designed tests of the abrasive wear resistance 2024 aluminum alloy strips under friction conditions involving various lubricants. Test were focused on the selection of the best lubricant for use in industrial environment, especially for sheet metal forming. Three lubricants of the Orlen Oil Company and one used in the sheet metal forming industry, were selected for tests. Tests without the use of lubricant were performed for a comparison. The tester T-05 was used for testing resistance to wear. As the counter samples were used tool steel - NC6 and steel for hot working - WCL, which are typical materials used for tools for pressing. The results are presented in the form of the force friction, abrasion depth, weight loss and coefficient of friction depending on the lubricant used and the type of counter samples. The results allowed for predicting set lubricant-material for tools which can be applied to sheet metal made of aluminum alloy 2024.

Galling is a known failure mechanism in many sheet metal forming processes. It limits the lifetime of tools and the quality of the products is affected. In this study, U-channel stamping experiments are performed to investigate the galling behavior of the advanced high strength steels in sheet metal forming . The sheet materials used in the tests are DP590 and DP780. In addition to the DP steels, the mild steel B170P1 is tested as a reference material in this study. Experimental results indicate that galling problem becomes severe in the forming process and the galling tendency can be divided into three different stages. The results also show that sheet material and tool hardness have crucial effects on galling performance in the forming of advanced high strength steels. In this study, DP780 results in the most heaviest galling among the three types of sheet materials. Galling performance are improved with increased hardness of the forming tool.

Innerhalb des Projekts „HyBlade“ wurde ein Flügelprofil aus Stahlblech entwickelt. Zum Einsatz kommen bewährte Fertigungstechniken wie das Abkanten einer Vorform und das Hydroforming zum Kalibrieren der finalen Geometrie. Das Verfahren stellt eine hohe Maßhaltigkeit sicher – die wesentliche Voraussetzung für gute Aerodynamik und hohe Energieausbeute von Windkraftanlagen. Die wirtschaftliche Prozesskette gestattet darüber hinaus auch die Herstellung größerer Blätter mit weitaus komplexeren Geometrien.   In the HyBlade project, a sheet metal based airfoil used for blades of small wind turbines has been developed. Well known forming techniques have been used to produce a bent preform that is finally calibrated via hydrofoming. This manufacturing technology ensures a high accuracy of the blade, resulting in good aerodynamic conditions and energy efficiency. The very cost-effective process chain furthermore offers the possibility to form even larger blades with a higher geometrical complexity.

Distortion Analysis

The sheet metal parts play important role in aero structures. Due to the requirement of strength and constraint of weight in aircraft, the aluminum alloy is widely used in sheet metal forming parts. Most of sheet metal parts form the contour in O-condition, and then solution treat to improve the strength and mechanical property. The deformation of sheet metal parts usually takes place after the heating cycle and quenching into the water or solution. The straightening operation will apply to corrective the contour of parts. Thus, the non-value added operation would increase the production cost. By using statistical methodology to analysis deformation data of sheet metal parts, this study use Cause-Effect Analysis to find the relation between deformation and relative factors, such as material, thickness and contour. The results of this analysis can provide an efficient and economical approach for the designer, process planner, and technician in manufacturing the sheet metal parts.

Good Agreement

In this study, the lump growth model, described in an accompanying paper (de Rooij and Schipper, 2000) is validated by means of experiments performed on a deepdrawing simulator. In the experiments, the influence of material and roughness properties of both sheet and tool on the galling behavior is determined. For these experiments, a deepdrawing simulator and a selection of aluminum and zinc coated sheets with several (coated) deepdrawing tools are used. Good agreement is found between results of the lump growth model and the sheet metal forming experiments.
