Leading quality, unique design, good handling, cost-effective.
Can be customized according to customer's requirements.
Can make Φ3000×16mm dished end.
Max. working pressure :25MPa
With this pressing machine,the spinned dished end have smooth surface,small round mark, good roundness, high productivity
Other model can be customized according to customer's demands
Extensive applications of dished end:
Dished end is a major part which on the end cap of pressure vessels,such us storage tanks, heat exchangers, towers, reaction kettles, boilers and separation equipment. So our machine is quite wildly uesd in these fields.
Pressing Machine specifications
Distance between main housings
Max. working pressure
Plate width of main bed frame
upper beam height 1500mm
inner height 2600mm
1,Pressing machine cylinder piston rod adopts chilled cast iron, cylinder adopts 35 # forgings, strokes ensure production of Φ3200mm ellipsoidal dish end.
2,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 5 tons.
3,The seller provides 5 sets pressing tooling, R600, R900, R1200, R1500, R1700, material QT600-3, marked with stamp.
4,With automatic and manual operation functions, pressure could display on gauge and adjustable
Dished end making process and other suggested machines:
1.CNC Gantry Flame and Plasma Cutting Machine
We use this machine to cut the plate. If small dish end, we can cut a whole circle directly, if big dish end, in order to save material, we usually cut two pieces, then weld them into whole circle.
After welding, we use this small trolley to grind the welding joint and get flat material.
3. YGJ Φ 3000×16mm Pressing Machine with pressing toolings
Then, we can load our flat material into pressing machine. This machine’s piston rod of the master cylinder moves up and down to drive the upper tool to press the raw plate to become the required concave shape.
4.FBJ Φ3000×16mm Flanging machine with toolings
Then, we load this concave shape plate into next machine: dish end flanging or edging machine. The clamping frame functions as the fix and free rotation of dish ends. Pressure wheels make movements based on certain round arc and put force on the dish end blank to make it rotate constantly to form dish ends and make thickness reduction minimum to achieve the ideal state.
