Leading quality, unique design, good handling, cost-effective.
Can be customized according to customer's requirements.
Can make Φ6500×40mm dished end.
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.

1, 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
2, A pressure wheel (mounted on the axle), and quenching treatment HRC46 ~ 50.
3, 17 forming wheels, R30,R50,R80,R100,R150,R200,R250,R300,R350,R400,R450,R500,R550,R600,R650,R700,R760,R820. Material QT600-3, marked with stamp. Forming wheel must have good abrasion resistance; dish end must have good gloss after spinning.
4, Make sure clamping cylinder work normally
5, Nut (for screw) strength: abrasion resistance must ZHA166-6-3-2 (aluminum brass), that is 9-4 copper.

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 6500×40mm Pressing machine
Flat material is loaded 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 Φ6500×40mm Flanging Machine with toolings
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.
