Zwick delivers Sheet Metal Testing Machine to Audi

The metallic materials used for shaped parts in automotive engineering are becoming stronger all the time. Higher-strength materials require higher testing forces. In other words, higher deep-drawing forces during forming. In order to do justice to these test requirements, Audi in Ingolstadt uses a Sheet Metal Testing Machine (BUP) from Zwick for deep-drawing forces up to 1,000 kN.

The metallic materials used for shaped parts in automotive engineering are becoming stronger all the time. Higher-strength materials require higher testing forces. In other words, higher deep-drawing forces during forming. In order to do justice to these test requirements, Audi in Ingolstadt uses a Sheet Metal Testing Machine (BUP) from Zwick for deep-drawing forces up to 1,000 kN.

The Sheet Metal Testing Machine BUP1000 for deep-drawing forces up to 1,000 kN contributes to determination of the necessary material characteristics and to quality assurance before further sheet metal processing. Together with the corresponding tools and accessories, the machine also serves to determine the forming limit curves (FLC) according to ISO 12004. The current version of this standard calls for a cupping-die diameter of 100 mm, and this also requires a higher force range up to 1,000 kN in this test on higher-strength materials. Further standard tests are possible simply by changing the tools: cupping tests according to Erichsen (DIN EN ISO 20482), earing tests (DIN EN 1669), square earing tests, hole expansion tests, as well as the bulge test.

The control technology of the BUP 1000 permits the forming test to be controlled via force and die travel measurement. This not only allows standard tests to be performed correctly but also permits forming processes to be simulated on a small scale. The max. die travel and the speed range of the cupping die cover a wide spectrum of applications.

The function display with remote-control option and the hydraulic operation of the tool head for specimen loading and unloading simplify handling in daily use. In order to study the forming process in detail, the deep-drawing force, the holding force and the cupping die travel can be read out via the testControl electronics and processed further and analyzed using the testXpert^® standard testing software from Zwick.
