Claims

[Scope of utility model registration request]

A metal plate to be processed is placed on the die, and with the metal plate curved in the deep drawing direction, the peripheral edge of the metal plate is placed between the peripheral edge of the die and a blank holder provided above the die so as to be freely raised and lowered. In a deep drawing machine, after pressing and holding the metal plate, the central part of the metal plate is deep drawn by being pressed between a punch and a die that are freely raised and lowered inside the blank holder.
Below the part of the metal plate supported on the die to be deep-drawn, a suction/detachment means that can be freely suctioned and removed from the lower surface of the metal plate, and a drive means that drives the suction/detachment unit freely up and down. Then, the suction/detachment means is raised by the drive means to adsorb it to the lower surface of the metal plate placed on the die, and then the suction/detachment means is lowered to hold the metal plate in a curved state in the deep drawing direction. A deep drawing processing device characterized by the following configuration.
