PURPOSE:To simplify working of conducting part material and reduce cost by providing a pressing device using rollers opposite to a heating device that heats the outer periphery of a metallic disk. CONSTITUTION:A heating device B is held between an upper die 6a and a lower die 6b and heats the outer periphery of a metallic plate 35 projecting in the concavity. At this time, a cylinder 27 is operated and a pressing device C is moved to a die fastening device A. One of rolling rollers attached to a mortar body 32 is thrusted against a heated metallic disk 35, and forming is performed in a concavity between upper and lower dies 6a, 6b. |
