Technical Strong Point of Welding Wuxi JACK Conventional Welding Turning Rolls

1. Importance: Welding Roller Rotator is one of the main welding machine tool products of Wuxi JACK, also one of the most extensive application ones;
2. Business: From 2009, benefiting from the large volumes of delivery on Welding Roller Bed over the past 15+ years, we have set up our own technical advantage and strong points on this widely used product of welding equipment;
3. So, as a series of product with common and universal structure and application, what distinguish Wuxi JACK Conventional Welding Turning Rolls from that of other suppliers?

The Delicate Design on Protection in Wuxi JACK Conventional Welding Turning Rolls:

Why proper protection on Welding Roller Bed and Welding Rotator so Important?

1. The Challenge on Working Staff, Environment, and Material during Operating on Welding Turning Rolls:

1) Work Surrounding: You know that as a kind of widely applied welding equipment, Welding Turning Rolls works in wide variety of rigorous working environment, which generates fairly volume of fume, dust, slags and debris during its working;
2) Workpieces: Besides, the workpieces laid on welding roller bed and welding turning rolls are usually large and heavy round barrels, which, not only easy to roll out, but also may do great harm on people surrounding;
2. For this reason, we need to take special care during developing standard Welding Turning Rolls, its welding roller bed and welding rotator, so that the welding machine tools can deliver the best working performance all the while, and the longest service life. This is what we should do as a responsible supplier on conventional Welding Turning Rolls;

3. Measures Taken on Protecting Wuxi JACK Welding Turning Rolls:

1) Mechanical: Carefully calculate on force condition and make analysis on the entire structure of Welding Turning Rolls, and its mechanical element. The welding roller bed can withstand the hardest test;
2) Drive and Electric Control: In terms of driving, transmission and control system of standard Welding Rotator, the whole line of involved outsourced parts, from motor, reducer, to A.C. inverter, to air breaker, fuse… Are all selected with sufficient margin of working specification. In this way, even under overload condition, the Welding Turning Rolls and its welding roller bed can still deliver satisfactory output;
3) Production: Every step throughout the production process of Wuxi JACK Welding Turning Rolls, is strictly carried out with fully protection on WIP (Working in process): You can see from the above photo that the welding rotator, revolving shaft of welding roller bed… are all applied with anti-rusting oil;
4) For hardware protection, as you can check from the above photo, that all the exposed transmission units in our Welding Turning Rolls, including transmission leadscrew, connecting shaft, are all covered with eye catching bright color housings;
5) Advanced Design: Relying on our senior engineering team with rich experience, Wuxi JACK develops series of Welding Turning Rolls to meet on customer advanced requirement: Hydraulic drive lifting/ Anti-drifting/ Hexagon prisms... These distinguish our welding rotator from other supplier’s products.

Operation and Application of Standard Welding Turning Rolls

1. When do You need Standard Welding Rotator?

1) Circumferential Welding: In the process of manufacturing assorted metal material barrel structure products, from small tube, to medium size pipe and cylinder, to large size and heavy weight tank, circumferential welding is an inevitable and core step;
2) Task: Welding Turning Rolls is the versatile and high efficiency machine tool for fulfilling this task, with the controllable and stable performance.

2. How does Welding Turning Rolls Work?

Welding Rotator is the necessary equipment for completing on job of circumferential welding on workpieces:
1) By loading the cylindrical workpieces onto its welding roller bed;
2) And under the drive of A.C. motor, the turning rollers revolve in certain adjustable revolutionary linear velocity;
3) The working part will then be led into rotation in the same revolving speed as the turning rollers. This is shown vividly in below design sketch of Wuxi JACK Bolt Adjust Welding Rotator: (Fig.1)

3. Operating on Welding Turning Rolls:

1) The leading force on rotation of cylindrical parts come from friction force generated between turning rollers and the cylindrical parts, during operation period;
2) Proper choice on material and process technology of turning rollers is the core step in developing Welding Rotator, especially heavy duty and anti-drifting welding roller bed, which determines on performance and service life of this welding machine tool;
3) Welding Speed Management: The revolutionary speed of turning roller is exactly the welding speed of working parts on welding roller bed. For this reason, this parameter in technical specifications of all the Welding Turning Rolls is changeable within certain scope, which is usually controlled with A.C. inverter, and displayed in digital meter: (Fig.2,3)

4) Quick understanding on product family of Welding Turning Rolls, is illustrated in summary page of “Advantages of Wuxi JACK Welding Roller Bed”.
