Claims

[Claims for Utility Model Registration] Two types of presses in which a first drawing tool and a second drawing tool each having a lower punch and an upper die are used and have mutually symmetrical shapes. One of the symmetrical press products is drawn by the first drawing tool, and the other symmetrical press product is drawn by the second drawing tool, and the first drawing tool is used to draw the other symmetrical press product. A structure of a blank holder that can be used both as a drawing tool and the second drawing tool, wherein the blank holder has a lower mold of the first drawing tool from one side thereof. It can be vertically movably fitted to the punch, and the second
The blank holder is capable of vertically movably fitting into the lower punch of the drawing tool, and a beat for suppressing wrinkles in the upper die of the first drawing tool is provided on the other side of the blank holder. A first beat portion corresponding to the blank is formed, and a second pin abutment is formed on the outer periphery of the first beat portion to which the upper end of the cushion pin of the second drawing tool comes into contact; A second beat part corresponding to the wrinkle pressing beat part in the upper die of the second drawing tool is formed on one side of the holder, and the first beat part is formed on the outer periphery of the second beat part. A blank holder structure for drawing forming, characterized in that a first pin abutment surface is formed on which the upper end of a cushion pin of a drawing tool comes into contact.
