Description
Technical Field
The invention relates to the technical field of special-shaped nuclear industry pipe processing, in particular to a multifunctional special-shaped nuclear industry pipe rotating matching device.
Background
At present, for a nuclear industry pipe with a thick-wall pipe, a common cutter is used for cutting, or a magnetic pipeline cutting machine is used for cutting, and the air inflow of oxygen and acetylene is adjusted according to the difference of the thickness of the nuclear industry pipe, so that the cutting of the pipe is achieved.

As shown in fig. 1, the cross section of the irregular nuclear industrial pipe 100 is a regular hexagon, and the center of the regular hexagon is located right above the second rotating shaft 21. The cross section profile of the first roller 1 is a first ellipse, the cross section profile of the second roller 2 is a second ellipse, the cross section profile of the third roller 3 is a third ellipse, and the shapes of the first ellipse, the second ellipse and the third ellipse are the same.

The perimeter of the first ellipse, the perimeter of the second ellipse, and the perimeter of the third ellipse are all 4 times the length of any one of the six sides of the regular hexagon. Setting: the major axis of any one of the first ellipse, the second ellipse and the third ellipse is a, and the minor axis of the ellipse is b; setting: any side length of the regular hexagon is x, the vertical distance from the middle point of the regular hexagon to any side is y, and the distance from the central point of the regular hexagon to the vertex of any angle is also x; the circumference of the ellipse is L, and the calculation formula of the circumference L of the ellipse is as follows: l ═ 2 pi b +4(a-b), in which case L ═ 4 x. During cutting, the first roller 1, the second roller 2 and the third roller 3 respectively support three adjacent surfaces of the special-shaped nuclear industrial pipe 100 and rotate around a rotating shaft of the special-shaped nuclear industrial pipe under the driving of the nuclear industrial pipe, and the three rollers are always abutted against the outer surface of the nuclear industrial pipe in the rotating process, so that a triangular supporting structure is formed, the supporting is stable and reliable, and the stability of the special-shaped nuclear industrial pipe 100 is effectively improved.
As shown in fig. 1, in the first extreme state, the apex of one of the outer corners of the regular hexagon is in contact with the circumference of the second ellipse, and the bisector of the outer corner is collinear with the minor axis of the second ellipse. Two angles adjacent to the outer angle in the regular hexagon are respectively a first angle and a second angle, the first angle is in contact with the first ellipse, the second angle is in contact with the third ellipse, a bisector of the first angle is collinear with a short axis of the first ellipse, and a bisector of the second angle is collinear with a short axis of the third ellipse.
