利用正交实验方法研究了感应电流、层下压量、进给速率对成形温度和成形极限

The orthogonal experiment method is used to study the influence and significance of induced current, sublayer pressure, and feed rate on forming temperature and forming limit. The results show that the influence of induced current on forming temperature and forming limit is the most significant. Second, the feed rate is the smallest. When the induced current is 50A, the sublayer pressure is 0.3mm, and the feed rate is 1000mm/min, the forming performance of the steel plate is the best, and the forming limit reaches 85.8°.

Using orthosectative experimental method, the influence and significantness of induction current, sub-layer pressure and intake rate on forming temperature and forming limit are studied, and the results show that inductive current has the most significant effect on forming temperature and forming limit, and the sub-layer pressure is second and the rate of infertation is the smallest. When the induction current is 50A, the down-layer pressure is 0.3mm, and the intake rate is 1000mm/min, the steel plate forming performance is the best, and the forming limit is reached 85.8 degrees.

The influence and significance of induction current, layer down pressure and feed rate on forming temperature and forming limit were studied by orthogonal experiment method. The results show that the influence of induction current on forming temperature and forming limit is the most significant, followed by layer down pressure and feed rate. When the induction current is 50a, the layer down pressure is 0.3mm, and the feed rate is 1000mm / min, the formability of the steel sheet is the best, and the forming limit reaches 85.8 °.<br>
