Многоосевой автоматический станок для резки труб с ЧПУ с расширенным управлением

 A. Come into Being of Multi Axis: From 3 Axis, to 5 Axis CNC Pipe Cutting Machine, to 6 Axis CNC Pipe Cutting Machine, to 7 Axis CNC Pipe Cutting Machine:

1.       3 Axis for Basic Function in CNC Pipe Cutting Machine:

Multi Axis is defined compared with the basic configuration of 3 Axis CNC Pipe Cutting Machine, which completes the task of pipe cutting, with the management of pipe length (X axis)/ diameter (Z axis) and periphery (Revolving, Y axis);

2. Expand to 5 Axis CNC Pipe Intersection Cutting Machine for Oblique Chamfer:

1)       To fulfil more advanced function of slant full circle beveling, Multi axis is introduced to CP series CNC Pipe Intersection Cutting Machine, starting from 5 Axis CNC Pipe Intersection Cutting Machine, which have the 4^th A axis and 5^th B axis for ±45° cutting torch tilting along pipe radial and axial direction respectively:

2)       The X/Y/Z/A/B axis in 5 Axis CNC Pipe Cutting Machine: (Fig.1)

3)       Elliptical cutting kerf delivered from Wuxi JACK 5 axis CNC Pipe Cutting Machine: (Fig.2)

3. Extend to 6 Axis CNC Pipe Intersection Cutting Machine for Large Pipes:

1)       Infinite revolving beveling can be realized with 5 Axis control in small to medium large diameter pipes: Φ600mm~Φ1400mm;

2)       When the pipe diameter exceeds Φ1400mm, and reaches the range of Φ2000mm to Φ2500mm, the solitary pipe revolving B axis can not manage pipe cutting and beveling satisfactorily in terms of both quality and quantity, and by this time V axis for cutting torch adjustment in radius way is used: This is 6 Axis CNC Pipe Cutting Machine:

3)       The V axis in 6 Axis CNC Pipe Intersection Cutting Machine: (Fig.3)

4. Extend to 7 Axis CNC Pipe Intersection Cutting Machine for Super Large Pipes:

1)       When diameters of pipe grow larger than Φ2500mm and reaches Φ3000mm, the 6^th V axis is not enough for adjusting cutting point in transverse way of the Large CNC Pipe Cutting Machine;

2)       By this time, the 7^th axis W axis needs to be introduced, which is lateral movement of friction rollers for supporting pipes. By changing the span of the 2 sets of friction rollers, larger pipes can be accommodated, and cutting torch can be controlled in this Large CNC Pipe Intersection Cutting Machine:

3)       The W axis in 7 Axis CNC Pipe Intersection Cutting Machine: (Fig.4)

B. Cutting Torch Analysis in 7 Axis/ 6 Axis/ 5 Axis CNC Pipe Cutting Machine:

1. One cycle of cutting torch action during running of the 7 Axis/6 Axis/ 5 Axis CNC Pipe Cutting Machine is indicated in below 9 frames of animation pictures: (Fig.5)

1)     Cutting torch swings leftward along pipe axial direction (B- Axis);

2)     Cutting torch swings forward slightly along pipe radial direction (A- Axis);

3)     Cutting torch swings forward still further and rightward along pipe radial direction (A- Axis, B- Axis) of the 5 Axis CNC Pipe Cutting Machine;

4)     Cutting torch swings backward and rightward slightly along pipe radial direction (A- Axis, B- Axis);

5)     Cutting torch swings backward and leftward still further along pipe radial direction (A- Axis, B- Axis) of the 5 Axis CNC Pipe Cutting Machine;

6)     Cutting torch swings backward and leftward along pipe axial and radial direction (A- Axis, B -Axis);

7)     Cutting torch swings backward and rightward along pipe axial and radial direction (A- Axis, B -Axis);

8)     Cutting torch swings forward and leftward along pipe axial and radial direction (A- Axis, B -Axis);

9)     Cutting torch swings forward and rightward along pipe axial and radial direction (A- Axis, B -Axis) of the 5 Axis CNC Pipe Intersection Cutting Machine;

2.       As complement, the V axis and W axis for operation of 6 Axis CNC Pipe Cutting Machine and 7 Axis CNC Pipe Cutting Machine:

1)       Meanwhile, pipe rotates (Y- Axis);

2)       To have precise positioning, the cutting torch moves forward and backward along pipe radial way (V- Axis), leftward and rightward along pipe radial way (X- Axis), and moves up and down to cater for changing height of pipe surface (Z Axis), in 7 Axis/ 6 Axis CNC Pipe Intersection Cutting Machine;

3)       And, catering for different diameter of workpiece, W- Axis of turning rolls adjustment is manipulated when loading a new pipe onto the 7 Axis / 6 Axis CNC Pipe Cutting Machine;

4)       From the above-mentioned example we can see how does the 7 Axis/ 6 Axis/ 5 Axis CNC Pipe Cutting Machine work.
