What are the structural features of the roller frame?

Structural features 1. It can be combined arbitrarily according to the weight and length of the weldment, which is convenient and flexible to use;
2. The roller center distance can be automatically adjusted within the specified range, which is suitable for weldments of different diameters, and cylindrical weldments can be placed stably;
3. It is driven by a thyristor-powered DC motor, with stepless speed regulation, a wide welding speed range, and stable speed;
4. It has strong applicability and is widely used;
5. The combined roller, the steel wheel is covered with rubber, with stable transmission, high friction, and long service life;
6. The wheel pressure on the workpiece is small, which can avoid cold work hardening on the working surface
Working principle
(1) The roller frame relies on the free swing of the roller pair to automatically adjust the roller center distance within the specified range, which is suitable for weldments of different diameters, and cylindrical weldments can be placed stably;
(2) It is driven by a thyristor-powered DC motor, with stepless speed regulation, a wide welding speed range, and stable speed; working hour quota. Statistics and summary of material consumption quotas, tool measuring tools and tooling, etc.
(3) Strong applicability and wide use;
(4) Adopting combined rollers, steel wheels covered with rubber, with smooth transmission, high friction and long service life;
(5) Self-adjusting roller frame, with many roller pairs and low wheel pressure on the workpiece, which can avoid cold work hardening on the working surface.
