Description
Technical Field
The utility model belongs to the technical field of metal plastic forming and shape correction, and particularly relates to an adjustable cylindrical shell section and end socket rounding tool.
Background
The cylinder of the pressure vessel has strict roundness requirement, and inevitably has deviation in the forming process of the cylinder, and the welding of the longitudinal welding line of the cylinder has inevitable welding deformation. Although the rolling machine is used for roundness correction in the longitudinal weld joint welding of the shell ring of the pressure vessel, the required shell ring roundness requirement is difficult to achieve in many cases, and particularly, the thick-wall shell ring is difficult to achieve.
At present, for the rounding of the shell ring and the end socket, a scheme of a ring plate with a notch and a wedge is mainly adopted, namely the ring plate with the notch is placed at a position of the shell ring to be rounded, then the wedge is inserted outside the notch, the wedge is struck, and the ring plate with the notch is propped by the wedging force of the wedge, so that the purpose of rounding the shell ring is achieved.
The existing cylindrical shell section and end socket rounding tools are mostly fixed-diameter tools, are generally suitable for single-diameter occasions, and have higher preparation cost; the existing single-diameter tool is multipurpose in mechanical force, hydraulic force and wedging force generated by a wedge, and due to the reasons of friction force and the like, the stress of the shell ring is uneven, and particularly the correction effect on a thick-wall shell ring is poor.
Disclosure of Invention
The utility model aims to solve the problems that a single fixed-diameter tool is poor in adaptability and high in cost in the pressure container industry mainly based on single-piece or small-batch production, and the correction force is insufficient in the application of a thick-wall cylindrical shell, and provides an adjustable cylindrical shell and end socket rounding tool.
The main technical scheme of the utility model is as follows: the adjustable cylindrical shell section and end socket rounding tool is characterized by comprising an annular plate and a support ring arranged in the annular plate, wherein a reinforcing support rod is arranged in the support ring; a base plate is arranged on the outer side of the ring plate, and a plurality of detachable adjusting cushion blocks are uniformly distributed on the outer side of the base plate.
Preferably, the support ring is a plurality of uniformly distributed rib plates or I-shaped steel support rings.
Preferably, the reinforcing support rod is a straight rod or a cross-shaped rod.
Preferably, the adjusting cushion block is fixed on the outer side of the cushion plate through a fastening bolt, a cushion block, a gasket and a nut.
Preferably, the outer side surface of the adjusting cushion block is provided with a groove for fastening the bolt.
The circle supporting tool provided by the utility model has the advantages that the purpose of circle supporting of cylinder sections or end sockets with different diameters is achieved by adopting the base plate, the uniformly distributed rib plates or I-shaped support rings (the smaller diameter can be a straight rod type reinforcing support rod and the larger diameter can be a cross type reinforcing support rod according to the wall thickness of the cylinder sections) and the adjusting base plate with adjustable thickness, and the larger correction force and correction precision can be obtained by a hot sleeving method during use.
The rounding tool can be suitable for cylinder sections with different diameters in a certain range by adjusting the thickness of the adjusting cushion block; the cylinder section port can be supported into a round port by using the same thickness of the adjusting cushion block; the thickness of the adjusting cushion blocks at different parts can be adjusted to locally correct the shape of different parts of the shell ring port, and the accurate roundness of the shell ring port can be obtained after the shape correction and the support removal.
The rounding tool can effectively correct the roundness of the cylindrical shell section or the end socket with different diameters and thicknesses, has a simple structure, is convenient to use, has a wide application range, and can be suitable for correcting the cylindrical shell section or the end socket with thicker and larger ovality.

Detailed Description
The present invention will be described in detail below with reference to examples and the accompanying drawings.
Examples
An adjustable cylindrical shell section and end socket rounding tool is shown in attached figures 1 and 2 and mainly comprises an annular plate 2 and a support ring arranged in the annular plate 2, wherein a reinforcing support rod 9 is arranged in the support ring; the outer side of the ring plate 2 is provided with a backing plate 3, and the outer side of the backing plate 3 is evenly provided with a plurality of detachable adjusting cushion blocks 5.
In the embodiment, the support ring is a plurality of uniformly distributed rib plates 1, and the reinforcing support rod 9 is a straight rod.
In the embodiment, the adjusting pad 5 is fixed on the outer side of the backing plate 3 through a fastening bolt 6, a pad 4, a gasket 8 and a nut 7, and a groove for fastening the bolt 6 is formed on the outer side surface of the adjusting pad 5 (refer to fig. 2).
The embodiment operates as follows: and confirming the size of the adjusting cushion block according to the diameter of the shell ring corrected according to the requirement and the outer diameter of the tool base plate, and assembling the tool after machining the adjusting cushion block.
The tooling supporting block is welded at the part of the shell ring needing to be circle-corrected, the shell ring is taken out after being heated in the heating furnace, the circle-supporting tooling is immediately placed at the part of the shell ring needing to be circle-corrected, and the shell ring is tightly wrapped on the circle-correcting tooling after being cooled, so that the purpose of circle correction is achieved. And after the shell ring is assembled and welded, detaching the rounding tool at a proper time.
Example the tooling was used for a barrel section (DN 3200mm X50 mm) in a certain reactor, and a 100mm adjusting pad was mounted on the tooling of DN3000mm to correct the barrel section with ovality of 48mm to 3.5 mm.
The rounding tool of the embodiment can be suitable for cylinder sections with different diameters within a certain range by adjusting the thickness of the adjusting cushion block; the cylinder section port can be supported into a round port by using the same thickness of the adjusting cushion block; the thickness of the adjusting cushion blocks at different parts can be adjusted to locally correct the shape of different parts of the shell ring port, and the accurate roundness of the shell ring port can be obtained after the shape correction and the support removal.
