Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connectors, and specifically relates to a lightweight and high-strength five-ring four-way part. Background Art

[0002] Publication No.: CN202082536U discloses a combined four-way pipe clamp. The pipe clamp includes two four-way halves that are snapped together. The two four-way halves can be snapped to form a cavity with four outlets. At each of the four outlets, there is an annular key adapted to the annular groove of the pipeline. A sealing ring adapted to its shape is also provided in the cavity. On the outside of the snap-together surface of the two four-way halves, ear plates are provided in pairs, and corresponding connection through holes are opened on the ear plates.

[0003] The above structure is a combined four-way pipe clamp that requires multiple components and is mainly used for pipeline construction. Its four circular ear holes are used to insert bolts for connecting pipelines and assembling the four-way halves. After the two four-way halves are assembled together, the pressure inside the four-way is concentrated on the four bolts. However, the bolts have low strength, which narrows the application range of the four-way pipe clamp. Moreover, the combination of multiple components generates extra weight to ensure the combination strength and cannot be used in lightweight and high-strength frame occasions. Content of the Utility Model

[0004] Aiming at the above-mentioned defects existing in the prior art, the purpose of the utility model is to provide a lightweight and high-strength five-ring four-way part. Through the combination of a four-way round pipe, a circular side ring, and a circular top ring, the integration of the ring and the pipe is realized, the rapid connection and disassembly of the frame cable are achieved, the overall strength and reliability of the part are effectively enhanced, and it can be applied to various lightweight and high-strength frame occasions. Through various data adjustments, the weight of the five-ring four-way part is reduced and the strength performance is enhanced, solving the problems of excessive weight and insufficient strength of the connecting parts in the frame structure.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A lightweight and high-strength five-ring four-way part includes a four-way round pipe. The four-way round pipe has four pipe walls, and a side ring is arranged at the connection of every two pipe walls. A top ring is arranged at the center of the top of the four-way round pipe. The side ring and the top ring are both circular rings. The four-way round pipe, the side ring, and the top ring are integrally formed.

[0007] Furthermore, internal threads are arranged at the ends of each pipe wall, and two locking holes evenly distributed circumferentially are arranged on each pipe wall in the internal thread area.

[0008] Furthermore, the connections between every two of the four pipe walls, between the pipe wall and the side ring, and between the four-way round pipe and the top ring are all arc-shaped transitions.

[0009] Further, the inner diameter of the four-way circular pipe ranges from 40 to 60 mm, the inner diameters of the circular side ring and the circular top ring range from 10 to 30 mm, the wall thickness of the four-way circular pipe is 2 mm - 6 mm, and the through-diameter length of the four-way circular pipe ranges from 100 to 300 mm.

[0010] Preferably, the materials of the four-way circular pipe, the side ring, and the top ring are light alloys.

[0011] More preferably, the materials of the four-way circular pipe, the side ring, and the top ring are aluminum alloys.

[0012] In another embodiment of the present utility model, the materials of the four-way circular pipe, the side ring, and the top ring are high-strength fiber-reinforced materials.

[0013] In another embodiment of the present utility model, the materials of the four-way circular pipe, the side ring, and the top ring are injection molding materials.

[0014] The present utility model has the following beneficial effects compared with the prior art:

[0015] 1. Through the integrated design of the four-way circular pipe, the circular side ring, and the circular top ring, the fixation of the internal cross cables during the frame assembly process and the fixation of the overall stay cables after the frame assembly are achieved, solving the problems of the relatively single function and low application rate of the conventional four-way structure, making the entire assembly process more efficient and rapid.

[0016] 2. By simplifying the design structure, optimizing the material selection, and using gravity casting molding, after molding, while reducing the weight of the parts, the mechanical properties such as the tensile strength and elongation rate of the parts are greatly improved. When in use, the entire four-way pipe is stressed, having a high service strength. Description of the Drawings

[0022] Among them, the four edge rings 2 are used for fixing the internal cross cables during the frame assembly process, and the four edge rings 2 also effectively strengthen the strength at the connection between every two of the four pipe walls.

[0023] Among them, the top ring 3 is used for fixing the overall stay cables after the frame assembly is completed.

[0024] Among them, the connections between every two of the four pipe walls, between the pipe wall and the edge ring 2, and between the four-way circular pipe 1 and the top ring 3 are all arc-shaped transitions, further reducing stress concentration and improving strength.

[0025] Among them, the internal thread is used for connecting pipes, and the locking holes 4 are used to further strengthen the connection strength between the pipes and the four-way circular pipe 1.

[0026] Among them, the materials of the four-way circular pipe 1, the edge ring 2, and the top ring 3 are all lightweight alloys, high-strength fiber-reinforced materials, injection molding materials, etc. The metal materials can be heat-treated after forming. Preferably, the lightweight alloy is aluminum alloy.

[0027] It should be noted that the lightweight alloy, aluminum alloy, high-strength fiber-reinforced material, and injection molding material are all existing technologies and do not involve improvements to the materials.

[0028] Through the combination of the four-way circular pipe 1 and the circular edge ring, the integration of the ring and the pipe is realized, effectively strengthening the overall strength and reliability of the part.

[0029] Embodiment 2:

[0030] Based on Embodiment 1, this embodiment provides a specific lightweight and high-strength five-ring four-way part. The structures of the four-way circular pipe 1, the circular edge ring 2, and the circular top ring 3 are all formed by gravity casting of aluminum alloy materials.

[0031] Specifically, the inner diameter range of the four-way circular pipe 1 is 40 - 60 mm, the inner diameter range of the circular edge ring 2 and the circular top ring 3 is 10 - 30 mm, the wall thickness of the four-way circular pipe 1 is 2 mm - 6 mm, and the through-diameter length range of the four-way circular pipe 1 is 100 - 300 mm.

[0032] The production process can be:

[0033] S1. Mold: Design the mold through the drawing, and the mold adopts a metal mold or a composite material mold.

[0034] S2. Raw material preparation: Prepare raw materials before production, including visual inspection of raw materials, chemical composition analysis, batching, and weighing various raw materials according to the batching calculation results. It also includes drying and weighing of refining agents and modifying agents.

[0035] S3. Melting: Add raw materials into the furnace according to the feeding sequence and melt them into an alloy with uniform chemical composition.

[0036] S4. In-furnace testing: After the alloy is melted evenly, take samples for testing to check whether various chemical components meet the requirements of technical standards.

[0037] S5. Adjusting composition: After testing, if it is found that one or several chemical components in the alloy exceed the provisions of the technical standards, adjustments shall be made to make the chemical composition meet the technical standards.

[0038] S6. Refining: After the chemical composition meets the requirements, use a refining agent to remove the dissolved gases and entrained solid particles in the alloy.

[0039] S7. Grain refinement and modification: Add appropriate grain refinement agents and modifying agents to the aluminum alloy liquid to improve the mechanical properties and machining performance of the alloy, etc.

[0040] S8. Melting and casting: Use an electric furnace to melt aluminum alloy for melting and casting. First, add aluminum alloy blocks into the electric furnace according to a specific formula and melt them. Add appropriate amounts of elements such as silicon and copper as alloying elements. The silicon content in the aluminum alloy is about 7%, and the copper content is about 3%.

[0041] S9. Pouring: After melting and casting are completed, the aluminum liquid needs to be poured into the mold. During this process, control the temperature of the aluminum liquid and the pouring speed. The melting point of aluminum alloy is relatively low, generally around 650 °C, and control the temperature of the aluminum liquid within this temperature range. At the same time, the pouring speed should be appropriate. Too fast will cause slag retention and is prone to defects; too slow will cause the aluminum liquid to solidify and also produce defects.

[0042] S10. Cooling: After the mold gets the aluminum liquid, it needs to be cooled and shaped. The cooling time depends on factors such as the size and shape of the mold. Smaller-sized molds are cooled within ten minutes, and large molds are cooled using a water cooling system.

[0043] S11. Demolding: After cooling, the formed part needs to be taken out of the mold. Use tools to gently tap the mold to make the formed part separate from the mold. So as not to damage the formed part.

[0044] S12. Post-treatment: After the formed part is taken out, post-treatment processes such as deburring, sandblasting, rough grinding, fine grinding, polishing, heat treatment, and machining need to be carried out. This process can make the surface of the formed part smoother and improve the brightness level.

[0045] In this application, any component itself that is not elaborated and the connection methods of various components in this application belong to the well-known technologies in the technical field. They can be directly applied and will not be elaborated further.
