Incremental Sheet Metal Forming

ncremental sheet metal forming with direct resistance heating is used for flexible sheet metal forming at elevated temperature, where electric current is conducted through the forming tool (s) into the forming zone. The electrical and mechanical contact combined with a high temperature of up to 600°C in steel forming results in complex tool requirements and a high wear of the tooltip. Starting with a description of a new process setup, both studies concerning existing and new tool concepts and materials will be presented in this paper. Therefore, the wear of different materials for tooltips and its dependence on lubrication has been investigated in forming experiments and will be thoroughly discussed.

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.
