BUP Sheet Metal Testing Machines
BUP Sheet Metal Testing Machines
With the BUP sheet metal testing machines, characteristic values of sheet metal forming are determined and evaluated. Sheet metal testing machines support development processes in the characterization of new alloys and new metalworking technologies, as well as in eventual series production.
The benefits of sheet metal testing machines are based on flexibility, easy and fast fixture changes for different tests, and the individually controllable integrated functions such as holding down, punching, drawing and ejection.
Typical Applications in Sheet Metal Forming
Typical sheet metal forming applications include the classical cupping test to Erichsen (ISO 20482) and Olsen (ISO 20482), the earing test (ISO 11531 / EN 1669) and hole-expansion tests to ISO 16630, which are seeing increasing use with high strength steel materials. Particular importance is attached to determination of the forming limit curve (FLC) to ISO 12004, which is used in a two-stage experiment to generate critical deformations in tests, which are then compared with existing deformations on real components and evaluated. Once the forming limit curve (FLC) has been determined, it is used during the component design stage to help optimize sheet metal forming, thereby speeding up the development process.
