Description

Technical Field

[0001] This utility model relates to a rounding tool, and more particularly to a rounding tool for preventing deformation of a cylindrical body. Background Technology

[0002] With the rapid development of the container manufacturing industry, large-diameter containers are being used more and more, such as pressure vessels and nuclear power plants. Among them, the cylinder is an important component in container manufacturing, and the shape and dimensional accuracy of the cylinder play a crucial role in the structural stability of the container.

[0003] The cylinder is prone to deformation during handling, turning, and machining. Generally, the larger the diameter and the thinner the wall thickness, the more severe the deformation, which has a greater impact on the subsequent machining and assembly accuracy, as well as the structural stability of the container.

[0004] For ease of description, cylinders with a diameter of more than 5 meters, a thickness of more than 20 millimeters, and a height of less than 6 meters are referred to as large-diameter cylinders. These large-diameter cylinders are usually made of rolled steel plates. Because these large-diameter cylinders have a large diameter, thin walls, and heavy weight, in order to ensure the strength and stability of the cylinder, a rounding tool is usually used inside the cylinder to reduce the deformation of the cylinder.

[0005] Currently used circular support fixtures typically employ straight-line, cross-shaped, or star-shaped supports. These circular support fixtures have the following main drawbacks:

[0006] (1) Poor stability: Although these supports can prevent the cylinder from deforming, their stability is relatively poor. Especially after the cylinder is rolled, welded and rounded, these supports cannot provide enough support force, which causes the cylinder to deform during transportation, lifting and transfer.

[0007] (2) Low efficiency: The installation process of these supports is relatively complicated, requiring precise adjustment and fixation, which takes a long time and affects production efficiency. Utility Model Content

[0008] The technical problem to be solved by this utility model is to provide a simple and easy-to-operate anti-deformation rounding tool for cylinders. With this tool, large-diameter cylinders are not easily deformed during handling, flipping, and machining. Therefore, the shape and size of the cylinder can be well controlled, ensuring the accuracy of subsequent machining and assembly. It is also applicable to occasions where the roundness requirement of the cylinder is within 3mm and the machining precision requirements of both ends of the cylinder are high.

[0009] To address the issues of poor stability, cumbersome adjustment, and low efficiency of existing cylindrical support fixtures such as straight supports, cross supports, and star-shaped supports, this invention designs a cylindrical anti-deformation support fixture. This fixture provides sufficient support force and is easy to adjust, greatly reducing the deformation of the cylindrical body and significantly improving production efficiency, ensuring that the final equipment can be delivered on schedule.

[0010] The technical solution adopted by this utility model is: the anti-deformation rounding tooling for a cylinder includes: an inner support assembly, the inner support assembly including a plurality of arc-shaped support plates, each arc-shaped support plate being arranged in a ring in sequence from end to end;

[0019] The adjustment support position locking assembly achieves double locking through the first connecting plate, each first threaded fastener, and the second connecting plate and each second threaded fastener, ensuring stable and reliable locking.

[0020] Furthermore, in the aforementioned anti-deformation rounding tooling for a cylindrical body, the structure of the wedge groove position locking assembly includes: a wedge block, a third connecting plate, and a fourth connecting plate; the wedge block is inserted into the corresponding wedge groove;

[0024] Furthermore, in the aforementioned anti-deformation support tooling for a cylindrical body, at least one fixed seat is provided on the top surface of each arc-shaped support plate, and at least one threaded fastener is provided on each fixed seat that can pass through the corresponding connecting hole on the side wall of the large-diameter cylindrical body and fix the large-diameter cylindrical body to the fixed seat.

[0025] By fixing each fixed seat to the large-diameter cylinder, the position of the inner support assembly is fixed, further ensuring that the inner support assembly can stably and reliably support the large-diameter cylinder.

[0026] Furthermore, in the aforementioned anti-deformation rounding fixture for a cylindrical body, each arc-shaped support plate has two fixed seats on its top surface.

[0050] In this embodiment, as Figure 2 As shown, the structure of the wedge groove position locking assembly includes: a wedge block 13, a third connecting plate 14, and a fourth connecting plate 15; the wedge block 13 is inserted into the corresponding wedge groove 4.

[0054] The assembly and disassembly process of the large-diameter cylinder 19 supported by the anti-deformation rounding tooling of the above-mentioned structure is as follows:

[0055] First, each wedge block 13 is placed in the corresponding wedge groove 4, each corresponding fourth connecting plate 15 abuts against the corresponding wedge block 13, and each fourth threaded fastener 18 passes through the corresponding fourth waist-shaped hole and is screwed into the corresponding fourth threaded hole, and each fourth threaded fastener 18 is not tightened; each third connecting plate 14 is placed on the top surface of the two arc-shaped support plates 2 at the corresponding wedge groove 4, and each third threaded fastener passes through the corresponding third waist-shaped hole 16 and is screwed into the corresponding third threaded hole 17, and each third threaded fastener is not tightened;

Then, the third threaded fasteners are tightened to lock the position of the corresponding wedge groove width. At this point, the inner support assembly 1 expands and adheres to the inner wall of the large-diameter cylinder 19. It is important to note that the insertion depth of the wedge block 13 must be controlled during the expansion process to control the overall expansion force of the inner support assembly 1, ensuring that the roundness of the cylinder is within the required range.

[0059] To improve the reliability of the connection, each third threaded fastener can be welded to the corresponding third connecting plate 14, and each fourth threaded fastener 18 can be welded to the corresponding fourth connecting plate 15.

It ensures that the shape and size requirements after machining can be controlled, and guarantees the accuracy requirements of subsequent machining and assembly.

[0077] In this embodiment, as Figure 6 , Figure 7 and Figure 8 As shown, at least one fixing seat 20 is provided on the top surface of each arc-shaped support plate 2, and at least one threaded fastener is provided on each fixing seat 20 that can pass through the corresponding connecting hole 21 on the side wall of the large-diameter cylinder and fix the large-diameter cylinder 19 to the fixing seat 20.

The positions of the corresponding two fixing seats 20 on all arc-shaped support plates 2 are the same.

[0079] The assembly and disassembly process of the large-diameter cylinder 19 supported by the anti-deformation rounding tooling of the above-mentioned structure is as follows:

[0080] First, each wedge block 13 is placed in the corresponding wedge groove 4, each corresponding fourth connecting plate 15 abuts against the corresponding wedge block 13, and each fourth threaded fastener 18 passes through the corresponding fourth waist-shaped hole and is screwed into the corresponding fourth threaded hole, and each fourth threaded fastener 18 is not tightened; each third connecting plate 14 is placed on the top surface of the two arc-shaped support plates 2 at the corresponding wedge groove 4, and each third threaded fastener passes through the corresponding third waist-shaped hole 16 and is screwed into the corresponding third threaded hole 17, and each third threaded fastener is not tightened;

[0083] Next, the position of the extended inner support assembly 1 is locked using the wedge groove position locking component.

[0088] The above-mentioned tooling has a simple structure, is easy to operate, and is inexpensive. Using this tooling can effectively prevent the large-diameter cylinder 19 from deforming during handling, flipping, and machining due to its large diameter and thin wall thickness. It ensures that the shape and size requirements after machining can be controlled, and guarantees the accuracy requirements of subsequent machining and assembly. It is also fully applicable to occasions where the cylinder roundness requirement is within 3mm and the machining precision requirements at both ends of the cylinder are high.
