5Axis Hydraulic Cylinder Automatic Welding Machine

I. Design Mission
1. Hydraulic cylinder automatic welding machine should meet the automatic welding of cylinder-tubes, piston rod with eye and end caps.
2. Hydraulic cylinder length: max 3600mm
3. Hydraulic cylinder diameter: Ф40-Ф400 mm
4. Make sure that welding specification is uniform, with good and smooth seam appearance. Convenient and reliable to operate. 
5. MIG welding with wire feeder.
6. Welding process will be continual and steady.

III. Welding Specification and Basic Feature
1. CNC system, control 5-dimensions action. It can be achieved 5 synchronizing interpolated motion.
2. The rotation speed of rotation axis is based on the rotary position of workpiece, to guarantee the consistency of welding linear speed.
3. PLC and 5 axis CNC control system to realize the above process, improve the reliability.
4.Machine can weld in a straight flat line. One of 5 axes can move forward and backward. Other exes will not move.
IV. Equipment Composition
Equipment is composed of machine body, rotary axis power mechanism, welding torch up&down, right&left and turning angle movement mechanism, welding torch clamping&adjustment mechanism, CNC control system, electrical control system and welding power source, etc.
