AI Technical Summary
Traditional flanges have poor sealing performance and are prone to leakage at the joints. In addition, the precision and roughness of large T-shaped sealing rings are difficult to meet the requirements during processing, especially the deformation problem of the T-arm is prominent.
A large T-shaped sealing ring processing tooling was designed, which adopted an inner support ring and screw rod structure. The top block was matched with the inner arc surface of the T-shaped sealing ring for support, avoiding T-arm deformation and ensuring processing accuracy.
It effectively prevents the deformation of the T-arm, ensures that the processing accuracy and roughness of the large T-shaped sealing ring meet the requirements, and improves the connection reliability of the sealing ring.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of equipment manufacturing, in particular to a large T-shaped sealing ring processing tool. Background Art
[0002] Traditional flanges rely on local plastic extrusion deformation of the gasket to achieve sealing, resulting in poor connection reliability and frequent accidents due to problems such as bubbling, dripping, and leaking at the joints. To address these issues, the applicant has developed a high-pressure self-tightening flange, which includes a ferrule, a sleeve, a T-shaped sealing ring, bolts, and a ball nut. Its sealing principle is that the two T-shaped arms of the T-shaped sealing ring cooperate with the sealing cone surface within the sleeve to form an elastic seal, thereby achieving high-pressure self-tightening.
[0003] The T-ring is the core component of a high-pressure, self-clamping flange. It consists of a central rib and two T-shaped arms. High-pressure, self-clamping flanges are designed in different sizes to match different pipe diameters. Larger pipe diameters require larger flanges, and in this case, a larger T-ring diameter.
[0004] When processing T-type sealing rings, the tolerance is required to be ±0.02mm, and there are also requirements for roughness. The roughness is When the tool is processing the T-arm of the T-shaped sealing ring, the tool squeezes the T-arm, resulting in the accuracy and roughness failing to meet the requirements. This problem is particularly evident for large T-shaped sealing rings. Utility Model Content
[0005] The purpose of the utility model is to provide a large T-shaped sealing ring processing tool, which can support the processing area on the T-shaped arm when the tool is processing the T-shaped arm, avoid deformation of the T-shaped arm, and solve the problems in the existing technology.
[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0007] A large-scale T-shaped sealing ring processing tooling includes an inner support ring, on which a number of screw rods are radially arranged around the center of a circle; the inner support ring is provided with openings matching the number of screw rods, one end of the screw rod passes through the opening on the inner steel ring and is tightened with a locking nut; a top block is provided at the other end of the screw rod, which contacts the inner ring surface of the T-shaped sealing ring; one side of the top block used to support the T-shaped sealing ring is an arc surface, and matches the inner arc surface of the T-shaped sealing ring; the top block supports the processing area of the processing tool on the T-shaped sealing ring.
[0008] As a preferred technical solution, the inner support ring is an inner steel ring.
[0009] As a preferred technical solution, the locking nut is a butterfly nut.

[0017] like Figure 1 As shown, a large T-shaped sealing ring 1 processing tool includes an inner support ring 22, which is an inner steel ring. A plurality of screw rods 33 are radially arranged around the center of the circle on the inner support ring 22. The inner support ring 22 is provided with openings matching the number of screw rods 33. One end of the screw rod 33 passes through the opening on the inner steel ring and is tightened with a locking nut 55. A top block 44 is provided at the other end of the screw rod 33, and the top block 44 is used to contact the inner ring surface of the T-shaped sealing ring 11. In this embodiment, the screw rod 33 is supported by providing the inner support ring 22, and the top block 44 is assembled by providing the screw rod 33, and is detachably connected to the inner support 2 for easy replacement; the T-shaped sealing ring 1 is supported by providing the top block 44.
