PULSED ELECTRO-HYDRAULIC CALIBRATION OF STAMPED PANELS |
摘要 |
A tooling method for calibrating a partially formed metal part in an electro-hydraulic forming tool. The method includes loading a partially formed metal part onto a forming surface of a die. The part is then clamped onto the forming surface and the part is pulsed with a high rate energy pulse to overcome a spring-back effect in the part. The EHF calibration tool includes a punch to which a part is held by clamps while a capacitive discharge circuit is discharged through electrodes provided in the tool. Upon discharge of the capacitive discharge circuit through the electrodes, a high rate energy pulse is applied through a liquid to calibrate the part.
