Abstract
Description
Technical Field
[0001] The present application relates to the technical field of titanium elbow sawing, and in particular to an auxiliary device for flush sawing of a titanium elbow port. Background Art
[0002] Pipe elbows are essential fittings used to change the direction of a pipe in a piping system. They connect two pipes and allow the pipe to bend at a specific angle. Elbows can be categorized into various types, depending on their angle, including 45°, 90°, and 180° elbows, as well as non-standard angles like 30° and 60°. Furthermore, there are specialized elbow types such as tees, reducing elbows, same-diameter elbows, and socket weld elbows.
[0003] Pipe elbows are widely used in various fields, including construction, drainage, HVAC, fire protection, water treatment, petrochemicals, ships, pumps, compressors, fans, and other piping systems. Pipe elbows are made of a variety of materials, including cast iron, titanium, alloy steel, carbon steel, non-ferrous metals, and plastics. Elbows made of different materials have different characteristics and applications. For example, titanium elbows offer excellent corrosion resistance and mechanical properties, making them suitable for applications involving corrosive media such as chemicals and petroleum. Plastic elbows, on the other hand, are lightweight and easy to install, making them commonly used in building drainage, HVAC, and other fields.
[0004] Common elbows usually have a curved section and horizontal sections extending from both ends of the curved section. The horizontal section is used to connect to the straight pipe. According to the installation requirements, the horizontal section can be set to different lengths. It is also possible to omit the horizontal section and directly use the port of the curved section to connect the straight pipe. However, in the actual installation process, due to the accumulation of errors when laying the pipe, there will be overlap between the straight pipe and the horizontal section of the elbow. Therefore, if Figure 2 As shown, sawing is usually performed along the dotted line to facilitate the smooth connection of the elbow and the straight pipe. When sawing the horizontal section, since the pipe body is perpendicular to the port, it is convenient to clamp the horizontal section and saw radially and vertically. For elbows without horizontal sections, and when there is an angle between the pipes connected on both sides, the sawing line must intersect with the center of the elbow to achieve flush sawing of the port. However, it is difficult to determine the center of the elbow when sawing. Therefore, the operator's rough marking sawing makes it difficult for the sawing line to intersect with the center of the elbow, that is, the port is not flush after sawing, as shown in the figure. Figure 6 As shown, this affects the sealing and tightness of subsequent connections with the pipeline. Summary of the Invention
[0005] In response to the above-mentioned problems, the present application aims to provide a titanium elbow port flush sawing auxiliary device, which can obtain the center base point of the titanium elbow, and on this basis, perform sawing through a sawing reference component, so that the port of the titanium elbow can be ensured to be flush after sawing, thereby improving the accuracy and sealing of the connection between the elbow and the pipeline after sawing.
[0006] In order to achieve the above-mentioned purpose, the technical solution adopted in this application is as follows: a titanium elbow port flush sawing auxiliary device, characterized in that: the flush sawing auxiliary device includes an assembly component for clamping the titanium elbow, and a centering component for obtaining the center of the titanium elbow is movably connected to the assembly component, as well as a sawing reference component with the center of the titanium elbow as the rotation base point.
[0007] Preferably, the assembly component includes an arc-shaped clamping plate that is in contact with the inner and outer circumferential surfaces of the titanium elbow, and a connecting screw is passed through the outer side of the arc-shaped clamping plate.
[0008] Preferably, a first hole is provided at the bottom of the connecting screw on one side; the centering member includes a centering rod that is flush with the port of the titanium elbow, and a second hole connected to the first hole is provided on one side of the centering rod, and a fastening screw is passed through both the first hole and the second hole.
[0009] Preferably, the sawing reference member is a reference rod rotatably connected to the fastening screw.
[0010] The beneficial effect of the present application is that the flush sawing auxiliary device first clamps and fixes the titanium elbow to be sawed through the assembly component. When the titanium elbow is fixed, the center point of the titanium elbow is obtained through the joint action of the centering component and the assembly component. On this basis, the center point obtained by sawing the reference component is rotated. After rotating to a suitable sawing position, sawing is performed based on the sawing reference component, so that the port of the titanium elbow can be ensured to be flush after sawing (the sawing line intersects with the center point of the titanium elbow), which improves the accuracy and sealing of the connection between the elbow and the pipeline after sawing.

[0024] In order to enable ordinary technicians in this field to better understand the technical solution of the present application, the technical solution of the present application is further described below in conjunction with the accompanying drawings and embodiments.
[0025] Refer to the attached Figures 1 to 11 A titanium elbow end flush sawing auxiliary device is shown, which includes an assembly component for clamping the titanium elbow, such as Figure 7 、 9 As shown, the titanium elbow that needs to be sawed is clamped and fixed by the assembly component. When the titanium elbow is fixed, it is convenient to use the centering component and the sawing reference component described later accurately, avoiding the rotation of the titanium elbow during use and affecting the use effect and the final sawing accuracy.
[0026] In order to solve the problem of incision deflection when sawing titanium elbows (especially arc sections), Figure 7 、 9 As shown, the assembly component is also movably connected to a centering component for obtaining the center of the titanium elbow, and a sawing reference component that uses the center of the titanium elbow as a rotation base point. The centering component and the assembly component work together to obtain the center base point of the titanium elbow. On this basis, the sawing reference component is rotated to the center base point obtained. After rotating to the appropriate sawing position, sawing is performed based on the sawing reference component. This ensures that the ends of the titanium elbow are flush after sawing (the sawing line intersects with the center of the titanium elbow).
[0027] Specifically, such as Figure 7-9 As shown, the assembly component includes an arc-shaped clamping plate 1 that is attached to the inner and outer peripheral surfaces of the titanium elbow, and a connecting screw 2 is provided on the outer side of the arc-shaped clamping plate 1. When assembling, the arc-shaped clamping plate 1 is assembled as shown in FIG. Figure 9 As shown, it is fitted on the inner and outer circumferential surfaces of the titanium elbow, and then connected and fixed from both sides of the arc-shaped clamping plate 1 through the connecting screw 2 to achieve fixed assembly of the assembly component and the titanium elbow.
[0028] like Figure 7 、 9 As shown, a first hole 2a is opened at the bottom of the connecting screw 2 on one side; the centering member includes a centering rod 3 that is flush with the end of the titanium elbow, and a second hole 3a connected to the first hole 2a is opened on one side of the centering rod 3, and a fastening screw 4 is passed through both the first hole 2a and the second hole 3a. When operating, as Figure 9 As shown, the centering rod 3 is placed flush with the end of the titanium elbow (since the centering rod 3 is connected to the fastening screw on one side, it is preferably set as a Z-shaped structure to facilitate the centering rod 3 to fit the elbow end), and then the fastening screw 4 is passed through the first hole 2a and the second hole 3a and fastened. The fastening screw 4 is the intersection of the connecting screw 2 and the centering rod 3, that is, the center of the titanium elbow is obtained.
[0029] Based on the center of the titanium elbow obtained above, Figure 10-11 As shown, the sawing reference member is a reference rod 5 rotatably connected to the fastening screw 4. One end of the reference rod 5 is sleeved on the fastening screw 4 and rotates with the fastening screw 4 as the center point of the titanium elbow. Figure 11 As shown, after the reference rod 5 is rotated to the position to be sawed, the titanium elbow can be sawed straight with the reference rod 5 as the sawing reference. The straight line of the port after sawing intersects with the center of the titanium elbow, thereby realizing a flush sawing port structure, which is convenient for precise connection with the pipeline.
[0030] The principle of this application is: when sawing the port of a titanium elbow, first fit the arc-shaped splint 1 onto the inner and outer circumferential surfaces of the titanium elbow, and then connect and fix it from both sides of the arc-shaped splint 1 through the connecting screw 2; then fit the centering rod 3 flatly onto the port of the titanium elbow, and then pass the fastening screw 4 through the first hole 2a and the second hole 3a and tighten it. The fastening screw 4 is the intersection of the connecting screw 2 and the centering rod 3, that is, the center of the titanium elbow is obtained.
[0031] Then, one end of the reference rod 5 is looped around the fastening screw 4, and the fastening screw 4 is used as the center point of the titanium elbow for rotation. After the reference rod 5 is rotated to the position to be sawed, the reference rod 5 is used as the sawing reference to perform straight sawing of the titanium elbow. The straight line of the sawed port intersects with the center point of the titanium elbow, thereby realizing a flush sawing port structure, which is convenient for precise connection with the pipeline.
[0032] The above shows and describes the basic principles, main features and advantages of this application. Without departing from the spirit and scope of this application, this application will also have various changes and improvements, which fall within the scope of this application.
