HLK High Quality Professional Adjustable Welding Rotator by Bolt

1. Specialty of HLK Series Bolt Adjusting Welding Rotator:

The HLK series Bolt Adjusting Welding Turning Roll, covers the widest range of tonnage and practical use in the entire product line. A brief comparison among the three broad product groups of HGZ/ HGK and HLK models Weld Roller Bed is as below:

1) Wuxi JACK HGZ series Self Adjusting Welding Rotator:  (Fig.1)

a) Strong Point: Easy operation, just put the workpiece onto its Weld Roller Bed and start on operation;

b) Weak Point: Relative narrow scope of Welding Turning Roll loading capacity: 5 Ton ~ 250 Ton for standard models;

2)  Wuxi JACK HGK series Leadscrew Adjustable Welding Rotator: (Fig.2)

a) Strong point: Quick and convenient operation; Continuous (stepless) adjusting center distance of Welding Turning Roll;

b) Weak Point: Confined to small loading weight of the Weld Roller Bed: Up to 60 Ton;

3) Wuxi JACK HLK series Bolt Adjusting Weld Roller Bed: (Fig.3)

a) Strong Point: Extensive range of loading tonnage capacity: Standard models is up to 1000 Ton, and special made heavy model up to 2000 Ton;

b) Weak Point: Relative low efficiency adjusting process on center distance of the Welding Turning Roll; Center distance change is in grades, not stepless;

Summing up, each type of the welding rotator has its upside and downside. For workpiece heavier than 250 Ton, which are often seen at projects of Oil Tank, Pipeline, and Offshore Tower, etc. only the HGK series Bolt Adjusting Welding Turning Roll can take on the job.

2. Classification on HLK Series Bolt Adjusting Weld Roller Bed:

Same as HGZ series Self Adjusting Welding Rotator, and HGK series Leadscrew Adjustable models, the HLK series also can be divided into standard type (conventional, typical, basic) and special made (Tailor made, custom made):

1) The HLK models standard type Bolt Adjusting Welding Rotator represents on fundamental design of this sub division of the product, and has the broadest use in practical condition. In general, it is a kind of stationary structured machine tool;

2) The special made Bolt Adjusting Welding Turning Roll cover: 

a) Manual or motor drive moving Welding Rotator;

b) Anti-Drifting Welding Rotator;

c) Other types of customer designated function added;

3) Among these special made Welding Turning Roll, the Anti-Drifting Weld Roller Bed is one of the most important products, which we will have discussion specifically in later on the dedicated product section. It is a kind of high quality sophisticated control product:

3. Working Principle of HLK Series Bolt Adjusting Welding Turning Roll:

1) Working Mode of HLK Models Welding Rotator:

With the help of frictional force generated between workpiece and leading section of Welding Turning Roll, the HLK series Welding Rotator put into rotation of the cylindrical workpiece, fulfilling on circumferential welding on the external surface of the workpiece;

2) Working Velocity of HLK Series Weld Roller Bed:

a) Welding speed of the workpiece, which is the rotation linear speed of the Welding Turning Roll, is controlled by means of adjusting revolving speed of A.C. inverter management:

 Welding speed management and display: (Fig.5)

b) This revolving speed in turn is controlled with A.C. inverter, or at early stage of the Welding Rotator, electro magnetic controller, with an operating contrivance such as turning knob, and shown in digital display. This makes operation less laborious and more convenient and intuitive;
