Function: our tank metal sheet spinning machine is used for forming
elliptical dish end for tanks and pressure vessels.Our machines are used in Petroleum or gas industry
Capacity:dish end making machine can make Φ4200mm cap
Advantage: We are professional manufacturer for dish end machine. In China,
70% dish end machines are made by us.We are leader of dish end
machine association, and drafted dish end machine standard.
Dish end making process:
1)Edging machine technical parameter:
Max. plate thickness S

2.Additional requirements of folding machine
a)The pressure of oblique cylinder, front cylinder, clamping must
show on pressure gauge and could be adjustable. The speed of front
and rear cylinders could be adjustable. Hydraulic station pressure
could show on gauge and adjustable
b)A pressure wheel (mounted on the axle), and quenching treatment
HRC46 ~ 50.
c)13 forming wheels,
Material QT600-3, marked with stamp. Forming wheel must have good
abrasion resistance; dish end must have good gloss after spinning.
d)Make sure clamping cylinder work normally
e)Nut (for screw) strength: abrasion resistance must ZHA166-6-3-2
(aluminum brass), that is 9-4 copper.
f)Inner height 2600mm ,Total height 4210mm
3.Pressing machine technical parameter

Main cylinder Max. working pressure
4.Additional requirements of pressing machine
a)Pressing machine cylinder piston rod adopts chilled cast iron,
cylinder adopts 35 # forgings, strokes ensure production of Φ4200mm
ellipsoidal dish end.
b) The pressing machine frame stiffness should be sufficient,
warranty for 10 years. When the upper mold pressure reaches to
20Mpa, Center deflection degree of upper and lower beam should not
exceed 1.8mm (achieve precision pressure level, the deformation f =
Δ / L = 1 / 2500). The cylinder piston rod should be chrome painted
and polished, machine load should be not less than 12 tons.
