Warm press forming equipment and warm press forming method

摘要

PROBLEM TO BE SOLVED: To provide a warm press forming apparatus and a method capable of directly heating a tip portion of a punch in contact with a work to put a processed region of the work into a warm state. A warm press forming apparatus 1 is an apparatus for processing a work 10 in a warm state using a punch 2 and a die 3. The punch 2 includes a punch body 20 having a bottomed cavity 2a, a rotating shaft 21 inserted inside the bottomed cavity 2a, a rotating jig 22 attached to the tip of the rotating shaft 21, and a bottomed cavity 2a. It is provided with a heat generating jig 23 fixed to the inner bottom surface. The warm press forming apparatus 1 includes a rotating device 24 for rotating the rotating shaft 21 and an urging device 25 for pressing the rotating jig 22 against the heat generating jig 23 via the rotating shaft 21. The warm press forming apparatus 1 heats the work 10 by the frictional heat generated by pressing the rotating jig 22 against the heat generating jig 23 using the urging device 25 and the rotating device 24 and rotating the rotating jig 22 to bring about a warm state.
