Sheet metal cup made of complex-phase steel
A sheet metal cup made of complex-phase steel is a rotationally symmetrical hollow body. Ernst Grob produces it by spinning on the R3 and T12 machines. In a complex-phase steel (CP steel), both the microstructure and the mechanical properties change during cold forming. In particular, the yield strength and the hardness increase significantly.
What is a sheet metal cup made of complex-phase steel?
A sheet metal cup is a cup-shaped, rotationally symmetrical hollow body made of sheet metal. It serves as the base body for components such as clutch plate carriers, brake disc pots and ring gear carriers.
- Reduced influence of anisotropy: In spinning, only a small area is worked at a time. As a result, the anisotropy of the initial sheet (the non-uniformity caused by the rolling direction) is less reflected in the finished part. (link to the explanation on the process page)
- Material savings and high quality: Forming enables economical use of material with high component quality.
Manufacturing at Ernst Grob
The sheet metal cup is produced by spinning; suitable materials include complex-phase steel, which acquires a significantly higher yield strength through cold forming. In addition, a sealing groove can be rolled.
