VIBRATION TYPE SHEET INCREMENTAL FORMING APPARATUS

摘要

PURPOSE: An excitation type board incremental formation device is provided to prevent a board from torning etc. generated in a shear deformation according to a conventional tool rotation. CONSTITUTION: An excitation type board incremental formation device comprises a board fixing unit (50), a die (10), a punch (20), a punch supporting part (21), an excitation unit (23), a punch transport unit (25), and an inverter (237). The board fixing unit fixes a formed board material. The die is prepared in one side of the board. The punch is prepared in the other side of the board. The punch supporting part supports the punch. The excitation unit performs a molding by pressurizing the punch with a vibration towards the board. The punch transport unit transfers the punch supporting part to a molding position fixed with corresponding to the board. The excitation unit comprises a first magnetic part and a solenoid. The inverter controls a frequency and a current strength of an alternating current inputted to the solenoid.
