Background technology of adjustable diameter rounding machine

During the transportation of the steel coil, the shaft end of the steel coil needs to be protected by cardboard, and the shape of the cardboard should correspond to the steel coil. Therefore, the hard support plate needs to be rounded to form a ring shape. Cutting along the template with a knife is not only low in work efficiency, but also prone to injury accidents. Today, Xiaobian will introduce the background technology of the adjustable diameter rounding machine.

The variable diameter rounding machine includes a rotating drum, and a circular support table is arranged on the drum. Above the support table, there are cutters on the inner circle, cutters on the outer circle and pressure rollers , the pressing roller is arranged on the upper knife on the inner ring between the cutter and the outer ring; the lower knife on the inner ring and the lower knife on the outer ring are respectively located under the support table.

The upper tool on the inner ring corresponds to the lower tool on the inner ring, and the upper tool on the outer ring corresponds to the lower tool on the outer ring; the upper tool on the inner ring, the upper tool on the outer ring, and the pressure roller are all threadedly connected with the upper screw, and the lower tool on the inner ring corresponds to the lower tool on the outer ring. Both the knife and the lower knife of the outer ring are connected to the lower screw, the bottom end of the upper screw is provided with an upper driven wheel, the end of the lower screw is provided with a lower driven wheel, the upper driven wheel is meshed with the lower driven wheel, and the lower driven wheel is meshed with the driving wheel. The driving wheel is fixed with the output end of the motor, and the worktable bracket is provided with tool through holes corresponding to the upper tool on the inner ring, the lower tool on the inner ring, and the upper tool on the outer ring, and the lower cutting tool on the outer ring.

The inner ring upper knife, the inner ring lower knife, the outer ring upper knife, the outer ring lower knife and the pressing roller are all provided with threaded holes, and the threaded holes are screwed on the upper screw or the lower screw; the inner ring upper knife , There are also inner locking nuts at both ends of the round lower knife, the outer round upper knife, the outer round lower knife and the pressing roller.
