Abstract
PURPOSE: To enable one process work preventing generation of burrs and early wastage of punches and dies by holding a blank with an energized movable second pressure plate to check coming up of the blank, and making flange work and blanking after making it precede completely.
CONSTITUTION: By descent of a punch holder 7, the second work pressure plate 10 comes into contact with a blank 12 on the first work pressure plate 5, and the blank 12 is pressed and fixed elastically by pressure plates 5, 10. Since elastic supporting power of the pressure plate 10 is set smaller than that of the pressure plate 5, the pressure plate 5 maintains stationary state and keeps the same height with a die 2. When the holder 7 further lowers a punch 8 contacts with the blank 12 and blanks it with the die 2. The pressure plate 10 comes into collision with the lower face of the holder 7 to become the limit of ascent. When the pressure plates 10, 5 go down in a united body by further descent of the holder 7, the pressure plate 5 lowers resisting against elastic supporting power, flange working of the blanking edge 12a is made between the edges of the pressure plate 10 and die 2.
