Easy Operation PR Model High Efficiency Pipe Rotator for Welding

1.       The Topic of this Product Section of PR series Table type Pipe Welding Positioner:

1)      In the preceding product sections of: PR series Universal Pipe Rotator for Welding, and Small Medium Size PR24 Downward Pressing Pipe Welding Positioner, for PR series automatic Pipe Rotating Machine, we have covered on topics of purpose, construction, drive and transmission, parameters and specification. If you are interested, please check;

2)      In this product section, we will discuss operation of the PR models Table type Pipe Welding Rotator.

2.       Operating Mechanisms in PR models Automatic Table type Pipe Rotating Machine:

Manipulation of this Pipe Rotating Machine is realized with four units:

1)      Control Board of the PR model Pipe Welding Positioner: (Fig.1)

Control cabinet of the PR model Table type Pipe Rotator is put alongside the equipment main body, on the floor and can be moved any time if necessary;

2)      Pushbuttons Integrated into Door of Pipe Rotator Control Board:

See attached picture. These buttons are for general control of the Pipe Welding Rotator: Power Switch On and Off, Alarm and Clear, Emergency Stop Button; 

Control Buttons of Pipe Welding Positioner: (Fig.2)

3)      Operating Pendant of the Weld Turning Roll:

a)       See attached picture. Concrete operating steps of this Table type Pipe Rotating Machine is performed on it: (Fig.3)

b)      This includes Weld Turning Roll Revolve Start and Stop, Weld Turning Roll Revolve FOR and RVR, Weld Turning Roll Revolve Speed Control and Its Digital Display, Pipe Welding Positioner Tilt Forward and Backward, Press of Weld Turning Roll Hold Down and Release, Emergency Stop of the Pipe Rotating Machine;

4)      Foot Pedal Switch of the Table type Pipe Rotating Machine: (Fig.4)

a)       See attached picture. It is for releasing operator’s hand for doing other jobs during work of the Pipe Welding Positioner;

b)      With the Foot Pedal Switch stepped down, the Weld Turning Roll and workpiece keeps on revolving;

c)       With the Foot Pedal Switch released, the revolving of the Weld Turning Roll and workpiece stops;

d)      In this way, one operator can easily operate this Pipe Rotating Machine.

3.       Technical Details in PR models Table type Pipe Welding Positioner:

1)      Two Grades of Square Slots for Adjusting Bottom Weld Turning Roll in Pipe Welding Rotator: (Fig.5)

a)       See above picture in red color square. In working table of the Pipe Welding Rotator, there are two grades of square slots cut in the top side of the two wall boards;

b)      The two sets of bottom Weld Turning Roll can be put into either grade of the square slots. This is for accommodating pipe, tube, elbow of various diameter in the Table type Pipe Rotating Machine;

2)      Leadscrew for adjusting Revolving Speed of Weld Turning Roll:

a)       At the front wall board of this automatic Pipe Rotating Machine, there is a leadscrew. See above picture in yellow color square;

b)      In case the Pipe Welding Positioner exhibits unstable revolving of the Weld Turning Roll, this leadscrew can be adjusted downward in certain degree, to tighten the sprocket of revolve;

3)      V shape and U shape Weld Turning Roll applied in the Pipe Rotating Machine:

a)       Besides standard round shape Weld Turning Roll as shown in the attached picture, there are also V shape and U shape Weld Turning Roll equipped in the Pipe Rotating Machine, which can be used for securing and welding flanges as well;

b)      So, we can see that this equipment is a genuine sense of general purpose Pipe Welding Positioner;

4)      Downward Travel of the Press Weld Turning Roll in the Pipe Welding Positioner:

The downward pressing of top Weld Turning Roll in PR models Pipe Rotating Machine, has two working modes of motor drive and manual: (Fig.6)

a)       First the top Weld Turning Roll descends under the guide of sliding shaft, which is driven and transmitted with leadscrew and nut, in the speed of 245mm/min.;

b)      Meanwhile, by manipulating the manual spanner at the top of the downward traveling unit, the top Weld Turning Roll can be managed downward in inching mode, until it presses workpiece of the Pipe Rotating Machine tightly.

4.       Technical Parameters of PR models Table type Pipe Rotating Machine:

1)      With this we come to the completion of introduction on PR series General Purpose Pipe Welding Positioner. Special design model is available;
