| description | To improve heating efficiency of an end face of an open punching end.SOLUTION: A forming method includes: a punching step of punching a steel plate, and thereby forming an open punching end where a part of an end face of the steel plate is opened; and a heating step of arranging a heating coil in a non-contact state along the end face of the open punching end formed by the punching step so as to sandwich the end face of the open punching end, allowing AC current to flow through the heating coil and generating an induction electromotive force in the steel plate, and thereby heating the end face of the open punching end. A current direction of the heating coil arranged on one side of the end face of the open punching end is opposite to a current direction of the heating coil arranged on the other side of the end face of the open punching end.SELECTED DRAWING: Figure 1
【課題】開放打ち抜き端の端面の加熱効率が向上させること。【解決手段】成形加工方法は、鋼板を打ち抜くことで、鋼板の端面の一部が開放された開放打ち抜き端を成形する抜き工程と、加熱コイルを、抜き工程による開放打ち抜き端の端面に沿って非接触の状態で、かつ開放打ち抜き端の端面を挟み込むように配置し、加熱コイルに交流電流を流し鋼板に誘導起電力を生じさせることで、開放打ち抜き端の端面を加熱する加熱工程と、を含む。開放打ち抜き端の端面の一方側に配置された加熱コイルの電流方向は、開放打ち抜き端の端面の他方側に配置された加熱コイルの電流方向と逆である。【選択図】図１ |
