Quick Detail:

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.

 
Specifications

Additional requirements 

1,The piston rod and barrel of the drum press machine master cylinder adopt chilled nodular iron, 35# forgings and 16Mn hot rolling steel plates respectively. Strokes can guarantee production of Φ5200 ellipsoidal dish ends

2,The main body section stiffness of the drum press machine should be sufficient, warranty for 10 years. When the upper mold pressure reaches 20Mpa, the beam center deflection degree can’t exceed 2.5mm (deformation f=Δ/L=1/2500) and the operating machine load can’t be less than 10T.

3,The seller provides 6 sets of drum press toolings, those are, R700, R900, R1200, R1500, R1900, R2500, whose material is high quality nodular cast iron with steel stamp.

4,Functions of automatic and manual operations are equipped. Pressure is shown on the gauge and can be adjusted.

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.

2.Grinder

After welding, we use this small trolley to grind the welding joint and get flat material.

3.YGJ Φ 5200×30mm 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 Φ5200×30mm Flanging machine with toolings

After that, 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.

5.Edge trimmer

It is used to cut dished end uneven edge.

6.Got dished end finally.
