PROBLEM TO BE SOLVED: To provide a press forming method for improving the dimensional accuracy of a pressed panel after warm forming.SOLUTION: In a warm press forming method of a steel sheet, by which deep draw forming into a die shape is performed by inserting and pressing the steel sheet with an upper and a lower dies and fold pressers after heating the steel sheet within the range of 400-700°C, the temperature drop of the steel sheet is prevented by providing groove shapes for moderate cooling are provided on both of the upper and the lower dies, or either of the upper and the lower dies, fold pressers, the upper die or the lower die. |
