Title:
Ｌ字状形状を有する部品のプレス成形方法
Document Type and Number:
Japanese Patent JP5796560
Kind Code:
B2
Abstract:
The present invention provides a forming method that forms a press component with an L shape (10) from a blank metal sheet (S), the press component having a top sheet section (11) and a vertical wall section (12) which is connected to the top sheet section (11) via a bent section (15) having a part curved in an arc shape (15a) and which has a flange section (13) on an opposite side to the bent section (15), the top sheet section (11) being arranged on an outside of the arc of the vertical wall section (12), the method including: disposing the blank metal sheet (S) between a die (51) and both of a pad (52) and a bending die (53); and forming the vertical wall section (12) and the flange section (13) while at least a part of the blank metal sheet (S) is caused to slide on a part of the die (51) corresponding to the top sheet section (11), the forming of the vertical wall section (12) and the flange section (13) being performed in a state where the pad (52) is made close to or brought into contact with the blank metal sheet (S).
