Just checking its appearance, we can easily find this type of special made Welding Turning Roll is obvious different from traditional standard HGK Leadscrew Adjusting Welding Roller Bed, in the below aspects of:
1) There is a set of elevating carriage fit in the standing rack of this special made Weld Rotator. This whole mechanism is never seen in the conventional general purpose Welding Rotator: (Fig.1)
2) Elevation of this lifting carriage in the Leadscrew Adjusting Welding Turning Roll is powered with a motor reducer (worm gear) at the top of the standing rack, please check the attached photo;
3) Standing rack of the Welding Rotator has the height of around 1.5m~ 1.8m, depending on specific design on the Leadscrew Adjusting Weld Rotator;
4) There is a piece of small Turning Roll fit at the front end of the elevating carriage, in the Welding Rotator: (Fig.2)
5) We call this specific designed Weld Turning Roller as “Down pressure type Leadscrew Adjusting Welding Rotator”, because of the above mentioned lifting carriage and the small Turning Roll, which move downward and press the workpiece tightly during working of the Welding Rotator;
6) So, what is the reason on introducing such kind of custom made Leadscrew Adjusting Welding Rotator? And what is its technical specialties? Let us review it one by one next.
1) In the high speed rotation of small diameter cylindrical parts on the Leadscrew Adjusting Weld Turning Roller, one often happened issue is workpiece slippage;
2) To solve this problem, we apply a pressing force onto the revolving workpiece in the Welding Rotator, by means of the small Turning Roll pressed on its top firmly. This small Turning Roll we show it in the last segment;
3) Hence takes shape and idea of this special design professional Leadscrew Adjusting Welding Roller Bed.
Please check below picture on the Leadscrew Adjusting Weld Rotator: (Fig.3)
1) There are limit switches at both ends of elevating stroke of the lifting carriage (In yellow color frame), in this special made Weld Turning Roller;
2) At its bottom extreme position, the small pressing Turning Roll (In purple color frame), can still be adjusted by hand in inching mode, with the handwheel at its top (In orange color frame), this gives more ample room for precise pressing of smaller workpiece in the Welding Roller Bed;
3) In this special made Leadscrew Adjusting Welding Rotator, revolve of the driving Turning Roll is powered with gear type reducer --- This is different from worm gear reducer in the standard model of HGK Leadscrew Adjusting Welding Roller Bed. It has higher degree of precision and ability to deliver larger torque, which is suitable to be used in this high quality Welding Rotator;
4) 6 Edge Rod is used to make transmission of the 2 pieces of driving Welding Turning Roll. Please check the other product using the same 6 Edge Rod in the product section of “HGK High Precision Special Made Leadscrew Adjusting Welding Rotator”;
5) In this special Welding Rotator, only the driving section of Welding Roller Bed has standing type rack for pressing the Turning Roll;
6) The 2 pieces of driving Turning Roll are made of rubber; The small down pressing Turning Roll is made of polyurethane.
1) This special made Welding Rotator belongs to stationary general purpose Welding Roller Bed: No movement function. For traveling type of the Weld Turning Roller, please check product section of “HGK Automatic Electric Travelable Leadscrew Adjusting Welding Rotator”;
2) If necessary, we can have more upgrade on this special made Welding Rotator. For example, making it travelable.
