Abstract
PURPOSE: To obtain the product of good quality without producing any flaw, galling etc. in the product and dies by removing the folds and cambers produced in the flange part with the working rolls on the dies.
CONSTITUTION: The work 1 is positioned on a die 2 and a cushion pad 3 in a manner that it is bent in a lengthwise direction to a product web surface shape. Next, as a punch 4 descends, the work 1 is sandwiched by a punch 4 and the pad 3, and is bent along the die 2 while allowing to contact with the same. A flange 1' is press- fitted into the die 2 while rising. When folds and cambers begin to be produced in the elongated and contracted flange at this time, work rolls 7 roll on the folds and cambers because the gaps between the rolls 7 and the punch 4 have been set at or below the plate thickness. The rolls 7 level said parts while compressing these in the plate thickness direction, and the punch 4 descends while sandwiching the material 1. When the flange end goes out of the rolls 7, the product is taken out.
