Abstract
PURPOSE: To decrease the number of steps and work the product of a large side with simple bending work by flexing the leading end part of a blank material to 3 steps.
CONSTITUTION: A blank material 15 is drawn with a press to form a flange 15b corresponding to a flange 12b, and a flange 15c longer than a flange 12c at the front end of the material 15, and form only the flange 15c corresponding to a flange 13a to the rear end of the material 15, whereby a 1/3 progressed product is made. Next, the front and rear ends of the flange 15c are trimmed, and the flange length of the 1/3 progressed product after the trimming is made equal to 12c and 13bW13e, whereby a 2/3 progressed product is made. Finally, the flange part 15a corresponding to the flange 12a of a package tray part 12 is formed by using a retainer 16, a lower die curved blade 17 and a male die curved blade 18; at the same time, the parts 15dW15g that are the flanges 13bW13e of an upper back part 13 are formed in the rear part of the material 15, whereby the forming of the 3rd progressed product, that is, a panel package tray to upper back 12 is completed.
