発明の名称 (英語) DEEP-DRAWING DEVICE
発明の概要(英語) A deep-drawing device that applies optimum heating and cooling to a plate material to increase a limit drawing ratio, performing working of a deeper product, and that can control the uniformity of the plate thickness of a product. The deep-drawing device has a punch (2) for deep-drawing a plate material (9), a die (3) for shaping and deep-drawing the plate material along with the punch, a wrinkle pressing section (4) for preventing an occurrence of wrinkles at the peripheral edge of the shaped section of the plate material, an induction heating coil (5) for directly heating that portion of the plate material that is held by the wrinkle pressing section, a heating control section (6) for controlling the amount of heating of the plate material effected by the induction heating coil, and cooling means (21-23) for cooling that portion of the plate material that is shaped by the punch.
