Description

Technical Field

[0001] This utility model belongs to the technical field of welding auxiliary equipment, and more specifically, relates to an adjustable metal welding gasket. Background Technology

[0002] Currently, various pipes often require welding of components such as sealing plates inside. However, when one end of the sealing plate is long, it is difficult to weld on both sides, and single-sided welding is difficult to guarantee strength. Therefore, in the existing technology, ordinary welding gaskets are generally used for single-sided welding and back-side forming.

[0003] However, further research has shown that most existing ordinary welding gaskets are rigid and can only be used for fixed sizes; moreover, when welding curved surfaces such as pipes, poor fit may lead to insufficient protection, which in turn affects the welding quality.

[0004] Accordingly, further research and improvement are urgently needed in this field to better meet the comprehensive requirements for high-quality and efficient completion of internal pipe welding. Utility Model Content

[0005] In view of one or more of the above-mentioned defects or needs of the prior art, this utility model provides an adjustable metal welding gasket. By studying and improving its overall structure and its setting method, the size of the gasket can be adjusted by air pressure to more accurately fit the welded parts. The gasket block is easy to disassemble and replace and can be reused. It also has the advantages of compact structure, easy operation, low cost and high welding quality. Therefore, it is particularly suitable for applications such as welding sealing plates inside pipelines.

[0006] To achieve the above objectives, according to this utility model, an adjustable metal welding gasket is provided. This adjustable metal welding gasket is assembled from multiple identical card components into a circular structure. Each card component includes a base plate, a first card slot, a gasket block, a card slot pad block, and a second card slot, wherein:

[0007] The first slot and the second slot are both sliding groove structures processed from a section of arc-shaped metal plate, and they are arranged on the base plate in an upper and lower opposing manner;

[0008] The pad block is installed on the first slot and the second slot. One end of the pad block is groove-shaped for sliding on the first slot and the second slot, and the other end of the pad block is arc-shaped for keeping in contact with the cylinder, which is the welded part.

[0009] The slot pad is disposed between the first slot and the second slot and forms a chamber at the rear of one end of the slot of the pad. The chamber is equipped with a hose connected to an external air source for introducing compressed air.

[0010] As a further preferred embodiment of this utility model, multiple bolt holes are provided at corresponding positions of the base plate, the first slot, the slot pad, and the second slot, and are used to screw in fixing bolts to achieve installation and fixation.

[0011] As a further preferred embodiment of this invention, the number of bolt holes is three, and they are designed to be evenly spaced.

[0012] As a further preferred embodiment of this invention, the pad block is made of platinum alloy.

[0013] As a further preferred embodiment of this invention, the pad block is removable and recyclable.

[0014] As a further preferred embodiment of this invention, the slot pad has an annular block structure.

[0030] Figure 1 This is a schematic diagram of the construction of each card component of the adjustable metal welding gasket provided in this application. Figure 2 This is a schematic diagram of the overall assembly of all card components into a metal welded gasket according to this application. The following will be combined with... Figure 1 and Figure 2 To explain this utility model in more detail.

[0031] like Figure 1-2 As shown, the adjustable metal welding gasket of this utility model is used for applications such as welding sealing plates inside pipes. The adjustable metal welding gasket is assembled into a ring structure by multiple card components with the same structure. Each card component includes a base plate 2, a first card groove 3, a gasket block 4, a card groove pad block 5, and a second card groove 6. These will be described in detail below.

[0032] like Figure 1 As shown, the first slot 3 and the second slot 6 are both sliding groove structures processed from a section of arc-shaped metal plate. They are arranged on the base plate 2 in an up-down opposite manner. The pad block 4 is installed on both the first slot 3 and the second slot 6. One end of the pad block 4 is groove-shaped for sliding on the first slot 3 and the second slot 6, and the other end of the pad block 4 is arc-shaped for keeping in contact with the cylinder 1, which is the welded part.

[0033] In addition, the slot pad 5 is disposed between the first slot 3 and the second slot 6 and forms a chamber at the rear of one end of the slot of the pad 4. The chamber is equipped with a hose connected to an external air source for introducing compressed air.

[0034] More specifically, such as Figure 2As shown, the adjustable metal welding gasket of this utility model is composed of four card components, which are assembled into a circular structure. Each card component includes a base plate 2, a first card slot 3, a gasket block 4, a card slot pad block 5, and a second card slot 6. Bolt holes 8 are provided at corresponding positions on the base plate, the first card slot 3, the card slot pad block 5, and the second card slot 6 for screwing in fixing bolts to achieve installation and fixation. For example, spot welding can be used to make the four card components form a circular ring together. The first card slot 3 and the second card slot 6 are both identical circular metal plates with multiple grooves for the sliding of the gasket blocks 4. The gasket blocks 4 are preferably made of white copper alloy, which has good thermal conductivity and high temperature resistance. One end of the gasket block is grooved and can slide on the first card slot 3 and the second card slot 6, while the other end is an arc-shaped surface that can fit more closely to the cylinder 1. In addition, the slot pad 5 is an annular block added to the first slot 3 and the second slot 6, which separates the two slots and forms a chamber; a hose is added into the chamber, one end is tied, and the other end is filled with compressed air, which can push the pad 4 out of the first slot 3 and the second slot 6, thereby more tightly fitting and clamping the cylinder 1.

[0035] The working process of the adjustable metal welding gasket of this utility model will be described below.

[0036] like Figure 3 As demonstrated in the example, when in use, compressed air is introduced into the hose, the gasket 4 is lifted and clamps the cylinder 1, and components such as the sealing plate 7 are placed on the gasket. The gasket can stably support the sealing plate 7, and the side of the back of the sealing plate 7 closest to the gasket can be better formed during welding.

[0037] In summary, compared with existing equipment, the adjustable metal welding gasket of this utility model can adjust the size of the gasket by air pressure to more accurately fit the welded parts, and the gasket block is easy to disassemble and replace to achieve reusability. It also has the advantages of compact structure, easy operation, low cost and high welding quality. Therefore, it is particularly suitable for applications such as welding sealing plates inside pipelines, and has good practical value and application prospects.

[0038] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
