3 Fundamentals of press design

Sheet metal forming lines
Fig. 4.4.13 Layout of a line for the manufacture of truck side members
(F N = 50,000 kN, blanking shock damping and stroke limitation, 11 bed cushions,
25 slide ejectors, maximum off-center load: 25,000 kNm with electronic control
of parallelity)
In the case of presses with material transport transversely to the longitudinal
press axis, the sheet plates are guided between the press uprights
by means of a chain conveyor and a gripper feed device in synchronization
with the press cycle. After each stroke, the remaining plate
pushes the newly punched contoured blank onto the reverse outfeed
conveyor belt. When an operation has been completed, the waste strip
of the old plate must be disposed of together with the blanking waste
from the new plate.
The equipment used for destacking the bales of plates or contoured
blanks and the other elements of the line are the same as those used in
lines transporting the material in the direction of the longitudinal press
axis.
