HGZ-series Multi-functional Automatic Self Adjustable Welding Rotator for Pipe

1.  What is Purpose of HGZ series Self Adjusting Welding Rotator?

1)  Function:    As introduced in the product family of Welding Roller Bed (The same name of Welding Rotator, or Welding Turning Roll), Welding Rotator is an universal applied equipment for process technology of Welding, Fabrication, Assembly, and Testing of cylindrical workpiece, such as pipe, tube, vessel, tank, barrel, etc. In this respect, the equipment is a multi-functional Welding Turning Roll;

2)  Meanwhile, because welding takes the biggest share in its application compared with assembly, painting, and testing, this equipment is often called automatic Welding Rotator;

3) Wide Variety:  Although Welding Roller Bed is a kind of equipment which has “simple” structure and appearance, there are many variations with it in terms of tonnage, detailed design and function;

4) Currently in industry, the prevailing and recognized way of classification on Welding Turning Roll is on the basis of its welding roller bed center distance adjusting manner: Self Adjustable Welding Rotator, Adjustable Welding Rotator by leadscrew, and Adjustable Welding Rotator by bolt. Of which, the Self Adjusting Welding Roller Bed is the first major categories we introduce.

2. Structure and Working Principle of HGZ series Self Adjusting Welding Turning Roll:

1)  As its name implies, the HGZ series of automatic Welding Rotator has its roller span adjusted automatically, in the way of rollers swinging around its shaft when workpiece is put onto it;

2) To have deeper explore on this roller span adjusting process in the Welding Rotator, first we should make clear, that in the working of Self Adjustable Welding Roller Bed, what is the purpose on its roller span changed? Please check sketch of HGZ series Self Adjustable Welding Turning Roll as below:  

Design sketch of Self Adjusting Welding Rotator: (Fig.1)

3) From the above sketch we can see that, in the Self Adjusting Welding Rotator:

a)  That for a set of Self Adjustable Welding Rotator, its roller span is the counterpart of workpiece diameter in equipment parameters;

b) This is the reason why we need to change span of the two pairs of rollers: To accommodating workpiece (Cylindrical parts) of various diameters put on it;

c) Hence comes product species of HGZ Self Adjusting Welding Roller Bed, HLK series Welding Roller Bed Adjusting by Bolt, and HGK series Welding Roller Bed Adjusting by Leadscrew, within the full range of automatic Welding Rotator;

4) The HGZ series is the automatic Welding Rotator with the simplest operation of its kind: Just loading the workpiece onto its Welding Roller Bed, the span or distance between the tiltable roller beds (We often call it “Plier shape Rack”) will be changed accordingly to cater for this specific piece of workpiece, and hence holding angle (It should be within the range of 45°~ 110°);

5) Diversification in HGZ series Self Adjusting Welding Rotator:

a) On the basis of this “plain” construction (The standard type Self Adjustable Welding Rotator), with some function added to it based on customer demand, there comes transformations with this series of Welding Turning Roll;

b) For example, travelling type Self Adjusting Welding Rotator, roller bed adjustable type Welding Rotator… Which we will have discussion in the subsequent sections.
