Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary tooling for pressure vessel production, in particular to an auxiliary tooling for preventing cylinder deformation. Background Art

[0002] In the current industrial development, pressure vessels are widely used in industries such as oil refining and petrochemicals. The cylinder of the pressure vessel is generally formed by rolling steel plates, and then the cylinder is subjected to corresponding hole welding or structural welding according to the process parameters of different products. Since many cylinders are affected by various factors such as excessive thermal shrinkage of the material, excessive openings, excessive welding filling, and long welding time, the ovality inside the cylinder will be greatly affected. If the ovality inside the cylinder is deformed too much, it will directly affect the installation size of the pressure vessel, thereby affecting the subsequent normal production and causing quality accidents. This is an important key point for how to prevent deformation inside the cylinder during the manufacturing process. For this reason, our company has proposed an auxiliary tooling to prevent cylinder deformation. Utility Model Content

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] An auxiliary tooling for preventing cylinder deformation comprises an arc-shaped support plate, a connecting plate, connecting plate bolts and a wedge block. A positioning nut is fixedly installed on the surface of the arc-shaped support plate, and a single-head locking bolt is spirally inserted in the positioning nut.

[0006] Furthermore, there are four arc-shaped support plates in total, and five positioning nuts are fixedly mounted on the surface of each arc-shaped support plate.

[0008] Furthermore, the four arc-shaped support plates are connected end to end to form a circular ring, and the four arc-shaped support plates are connected and fixed by connecting plates and connecting plate bolts.

[0009] Furthermore, the connecting plate is fixed on the surface of the arc support plate by connecting plate bolts passing through the connecting holes and the connecting holes, and the adjacent arc support plates are connected to each other by another connecting plate bolt passing through the connecting hole and the connecting hole on another arc support plate.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] Embodiment 1:

[0019] like Figure 1-4 As shown, an auxiliary tool for preventing cylinder deformation comprises an arc-shaped support plate 1, a connecting plate 4, a connecting plate bolt 5 and a wedge-shaped block 6. A positioning nut 2 is fixedly installed on the surface of the arc-shaped support plate 1. A single-head locking bolt 3 is spirally inserted in the positioning nut 2. The single-head locking bolt 3 is pushed and tightened against the inner wall of the cylinder by screwing on the positioning nut 2, so that the shape of the cylinder does not become concave and becomes an elliptical shape.

[0020] There are four arc-shaped support plates 1 in total, and five positioning nuts 2 are fixedly installed on the surface of each arc-shaped support plate 1; connection holes 101 are provided on the surface of the arc-shaped support plate 1 near both ends, and embedded grooves 102 are provided on the convex arc surface of the arc-shaped support plate 1, and six embedded grooves 102 are provided on each arc-shaped support plate 1; the four arc-shaped support plates 1 are connected end to end to form a circular ring, and the four arc-shaped support plates 1 are connected and fixed by connecting plates 4 and connecting plate bolts 5; the connecting plate 4 is fixed to the surface of the arc-shaped support plate 1 by connecting plate bolts 5 passing through the connecting holes 101 and the connecting holes 401, and the adjacent arc-shaped support plates 1 are connected to the arc-shaped support plate 1 by another connecting plate bolt 5 passing through the connecting holes 401 and the connecting holes 101 on another arc-shaped support plate 1, so that the four arc-shaped support plates 1 are connected end to end to form an annular support, wherein the connecting plate 4, the connecting plate bolts 5 and the connecting holes 101 are all structural members for fixing and connecting the four arc-shaped support plates 1.

[0021] It should be noted that the utility model is an auxiliary tooling to prevent cylinder deformation, wherein the positioning nut 2 is welded on the surface of four arc-shaped support plates 1, the single-head locking bolt 3 is screwed on the positioning nut 2, and the four arc-shaped support plates 1 are connected by connecting plates 4 and connecting plate bolts 5, and after being tightened, they are made into a fixed ring shape, and then the ring support is placed in the easily deformed area during the cylinder welding process, and the wedge block 6 is squeezed into the embedded groove 102 of the arc-shaped support plate 1 to increase the support points near the welding area, and the single-head locking bolt 3 is tightened to push against the inner wall of the cylinder. In the area near the welding point, the strength of the wedge block 6 and the strength of the single-head locking bolt 3 to push outward should be increased, so that the support expansion force on the inner wall of the cylinder is sufficient to resist the deformation force generated during the welding process, and ensure that the ellipticity of the cylinder will not change due to the heat of welding.
