The large T-shaped sealing ring machining tool comprises an inner supporting ring, and a plurality of lead screws are arranged on the inner supporting ring around the circle center in a radial mode. Holes matched with the lead screws in number are formed in the inner supporting ring, and one ends of the lead screws penetrate through the holes in the inner steel ring and are tightened by locking nuts; a top block is arranged at the other end of the screw rod and is in contact with the inner ring surface of the T-shaped sealing ring; the face, used for supporting the T-shaped sealing ring, of the ejector block is an arc face and matched with the arc face of the inner side of the T-shaped sealing ring. The ejector block supports the machining area, on the T-shaped sealing ring, of the machining tool. By means of the technical scheme, when the tool is used for machining the large T-shaped sealing ring, the T-shaped arm is not prone to deformation.

Description

Technical Field

[0001] The invention relates to the technical field of equipment manufacturing, and 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, and the reliability of the connection is poor. The connection is prone to leakage, bubbling, dripping, and leaking, so accidents occur frequently. In order to solve the problems of traditional flanges, the applicant has developed a high-pressure self-tightening flange, whose structure includes: a ferrule, a sleeve, a T-shaped sealing ring, a bolt, and a ball nut; its sealing principle is: the two T-shaped arms of the T-shaped sealing ring cooperate with the sealing cone surface in the sleeve to form an elastic seal, thereby achieving high-pressure self-tightening.

[0003] The T-shaped sealing ring is the core component of the high-pressure self-tightening flange, including the ribs in the middle and the T-shaped arms on both sides. For different pipe diameters, high-pressure self-tightening flanges of different sizes will be designed to match them. When the pipe diameter is large, the high-pressure self-tightening flange also needs a larger size, and at this time, the diameter of the T-shaped sealing ring is also larger.

[0004] When processing T-type sealing rings, the tolerance is required to be ±0.02mm, and there are also requirements for roughness. When the tool is processing the T-arm of the T-shaped sealing ring, the tool squeezes the T-arm, causing the accuracy and roughness to fail to meet the requirements. This problem is more obvious especially for large T-shaped sealing rings. Summary of the invention

[0005] The purpose of the present invention is to provide a large-scale T-shaped sealing ring processing tool, which can support the processing area on the T-shaped arm when the T-shaped arm is processed by a tool, avoid deformation of the T-shaped arm, and solve the problems in the prior art.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is as follows: A large-scale T-shaped sealing ring processing tool comprises an inner support ring, on which a plurality of screw rods are radially arranged around the center of a circle; the inner support ring is provided with openings matching the number of the 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, and the top block contacts the inner ring surface of the T-shaped sealing ring; one side of the top block used for supporting 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.

[0007] As a preferred technical solution, the inner support ring is an inner steel ring.

[0008] As a preferred technical solution, the locking nut is a butterfly nut.

[0009] As a preferred technical solution, there are 8 top blocks.

[0010] Compared with the prior art, the present invention has the following beneficial effects: When processing large T-shaped sealing rings, the processing area on the T-shaped arm can be supported to prevent deformation and ensure processing accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 It is a structural schematic diagram of the present invention.

[0012] Among them, the figure numbers are as follows: 1-T-type sealing ring, 2-inner support ring, 3-screw, 4-top block, 5-locking nut. DETAILED DESCRIPTION

[0013] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0014] On the contrary, the present application covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present application as defined by the claims. Further, in order to make the public have a better understanding of the present application, some specific details are described in detail in the detailed description of the present application below. Those skilled in the art can fully understand the present application without the description of these details. Example

[0015] like Figure 1 As shown, a large T-shaped sealing ring processing tooling includes an inner support ring 2, and the inner support ring 2 is an inner steel ring. A plurality of screw rods 3 are radially arranged around the center of the circle on the inner support ring 2. The inner support ring 2 is provided with openings matching the number of screw rods 3. One end of the screw rod 3 passes through the opening on the inner steel ring and is tightened with a locking nut 5. A top block 4 is provided at the other end of the screw rod 3, and the top block 4 is used to contact the inner ring surface of the T-shaped sealing ring 11. In this embodiment, the screw rod 3 is supported by providing an inner support ring 2, and the top block 4 is assembled by providing the screw rod 3, 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 4.

[0016] Specifically, one side of the top block 4 used for supporting the T-shaped sealing ring 1 is an arc surface, and matches the arc surface of the T-shaped sealing ring 1 .

[0017] Preferably, there are 8 top blocks 4 and 8 screw rods 3 .

[0018] As a preferred embodiment, the locking nut 5 is a butterfly nut.

[0019] The working principle of this embodiment is: when the tool processes the T-shaped arm, the top block 4 is used to support the T-shaped sealing ring 1, and the top block 4 is located at the processing point at this time, thereby avoiding deformation of the T-shaped arm.

[0020] The structure of this embodiment is particularly suitable for processing T-shaped sealing rings 1 with large diameters (DN≥600 mm).

[0021] It is worth noting that, based on the above structural design, in order to solve the same technical problem, even if some insubstantial improvements are made on the present invention, they also fall within the protection scope of the present invention.
