Need Press Machine Manual
(OP)
I have bought a second hand press machine (dish end crowning machine),unfortunately i do not have any manual or any data , i know totally how can i full control in the machine (i know the function of each button on the machine).
so please , can any one tell me in details the steps from loading the circular flat blank on press to finish the crowning machine
or , does any one have a manual of a machine like that showing the steps of forming from a to z.

the machine is called.........HYDRAULIC PRESS WITH FIXED UPRIGHT + MANIPULATOR.... (SERTOM COMPANY)(made in Italy)
max work piece diameter = 5000 mm
max sheet thickness = 25 mm
max pressure = 25 Mpa = 250 bar
work piece dimensions :-
material = Steel 37
blank diameter = 3700 mm
sheet thickness = 14 mm
HV30 = 130( hardness value)
the target is to make a dish end with the following data :-
outer diameter = 3028 mm
total height = 712 mm
radius of crowning (from hydraulic press) = 3000 mm
radius of knuckle (from flanging machine) = 350 mm
length of straight flange = 100 mm
from my drawings (see the attachments)....the dish chord should be 3471 mm for the next process (Flanging machine),
now the chord is 3600 mm getting with 200 bar
should i increase the pressure to 250 bar to get the required chord (3471 mm), will it affect on the thickness
i do not know what should i do ? does any relation axist between pressure and thickness ?
