Easy Operation PR Model High Efficiency Pipe Rotator for Welding

1. Topic of This Product Section on PR Series Table type Pipe Welding Positioner:

1) In the preceding product sections of: PR series Universal Pipe Rotator, and Small Medium Size PR24 Downward Pressing, 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 pipe welding equipment.

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

Manipulation of this machine is realized with four units:

1) Control Board of the machine: (Fig.1)

As shown in the above photo, electric control cabinet 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; 

Pushbutton and switch on control cabinet door: (Fig.2)

3) Operating Pendant of the Weld Turning Roll:

a) See attached picture. Hand held operating pendant is used to conveniently operate the machine during work: (Fig.3)

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

4) Foot Pedal Switch for releasing hands of operator: (Fig.4)

a) See attached picture. It is for releasing operator’s hand for doing other jobs during welding work period;

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 yellow 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 on pipe, tube, elbow of various diameter in the Table type Pipe Rotating Machine;

2) Leadscrew for Adjusting on Revolving Speed of Weld Turning Roll:

a) At the front wall board of 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 in Pipe Rotating Machine:

a) Besides standard round shape Weld Turning Roll as shown in the attached picture, there are also V shape and U shaped ones equipped in the 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 positioner for pipe welding;

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

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

a) First the top Weld Turning Roll descends downward 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 tightly presses on workpiece.
