Forming Characteristics

The steel wheel centre discs are usually stamped by multi-stage sheet metal forming. The stage number and the content of every stage decide if the structure-pieces can be formed successfully and the final forming quality. In this paper, the forming characteristics of wheel centre disc were analyzed firstly and the reasonable two-stage stamping scheme of drawing and inverse-drawing are adopted. The numerical simulations of multi-stage stamping process are performed and connected together through deformation transmission. By means of FLD and changes of sheet metal chickness, the formability is analyzed and the forming process is optimized. The feasibility of multi-stage forming process simulation and the validity of the optimized scheme were verified by stamping in practice.

Optimisation Algorithms

The paper elucidates how to connect forming process simulation with innovative measurement- and analysis equipment thereby taking into account the machine influences. Reverse Engineering use 3D-Scanning data of sheet metal forming dies. Following this paradigm, the models simulation relies on are refined, and spotting of forming dies is subjected to a scientific analysis. That means, that with Reverse Engineering, “extended process engineering” is verified at the real spotting procedure, the comparison of simulation- and measuring results is used to evaluate how close the investigated models are to reality, extending the optimisation algorithms used for springback compensation to die spotting, the modification of the die topology will be carried out automatically thanks to new software functions.

Practical Recommendations

To determine the accuracy of the readjustable punches for separating operations (perforation + punching out) of sheet-metal forming, the accuracy parameters were analyzed using the random balance method using the method of experiment planning. Analytical dependencies are obtained to determine the values of deviation of the outer and inner contour dimensions of perforated and punched out sheet parts. From the dependencies obtained, it is possible to estimate and predict the value of deviation in the dimensions of the resulting part at any time during the operation of the punch. Practical recommendations on the calculation of the actuating dimensions of the working elements (stamping punch, matrix) of readjustable punches are offered.
