Working principle and structural characteristics of roller frame

Update time:2022-03-04 16:41:00Clicks:149
working principle: (1) The roller frame can automatically adjust the center distance of the roller within the specified range by the free swing of the roller pair, which is suitable for weldments with different diameters, and the round simplified weldmen

working principle:
(1) The roller frame can automatically adjust the center distance of the roller within the specified range by the free swing of the roller pair, which is suitable for weldments with different diameters, and the round simplified weldments are placed stably;
(2) It is driven by thyristor powered DC motor, stepless speed regulation, large welding speed range and stable speed; Statistics and summary of man hour quota, material consumption quota, cutting tools, measuring tools and tooling;
(3) Strong applicability and wide use;
(4) The combined roller is adopted, and the steel wheel is wrapped with rubber, which has stable transmission, high friction and long service life;
(5) The self-adjusting roller frame has many roller pairs and small wheel pressure on the workpiece, which can avoid cold work hardening on the working surface.
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. Automatically adjust the center distance of the roller within the specified range, which is suitable for weldments with different diameters, and the cylindrical weldments are placed stably;
3. Thyristor powered DC motor drive, stepless speed regulation, large welding speed range and stable speed;
4. Strong applicability and wide use;
5. Combined roller, steel wheel wrapped with rubber, stable transmission, high friction and long service life;
6. Reduce the wheel pressure on the workpiece to avoid cold work hardening on the working surface.
