Abstract

In this research the designed mechanism for CHASING AND REPOUSSE of sheet metal is studied. This mechanism is similar to INCREMENTAL SHEET METAL FORMING. In this kind of sheet metal forming, sheet surrounding is fixed and forming tool pastes the desired pattern on sheet metal incrementally. The major differences between designed mechanism and traditional incremental forming are as follows: control on the punch energy and sequence, and fixing the sheet by using protectant material behind it instead of clamping sheet sides. In this mechanism, the solenoid is used as a hammer. The plunger moves to the center of the coil while energized. Striking energy could be controlled by controlling the excitement voltage and punching sequence could be adjusted by manipulating the excitement algorithm. In this paper, the utilized solenoid is simulated. The mechanical and magnetic relations are merged for this. Flexible mesh is used to make it possible for the plunger to have movement. An experimental setup is executed to measure force on the plunger during stroke, this is used for validation. Plunger head is one important parameter affecting strike energy, thus an appropriate plunger head angle is investigated. Plunger mass is changeable, so this parameter is considered and drilled plunger is simulated. Finally, the effect of coil cover on strike energy and power is studied.
