Description
The forming processes for press of a thin sheet of steelThis invention is concerned to drawing area press forming method of thin steel sheet that allows press forming of drawing area, which has large bending angle, is located in the bottom and has the form of deep insertion, to be formed by unifying to the top edge of thin steel sheet.
In other word, It is the method to create total elongation(enlarged length) and same or similar uneven part(200) in the forming part(100) where the above drawing area(10) is formed, enable drawing area(10) to be formed with...
