[0001] This application relates to the field of copper alloy pipe processing, and in particular to a processing apparatus and method for seamless copper alloy pipes for marine applications. Background Technology

[0002] Currently, copper alloys are materials that combine copper with other metallic elements. Due to their excellent electrical and thermal conductivity and good ductility, they are widely used in many fields such as electrical engineering, machinery, and construction. For some copper alloy products that require complex shapes or special structures, such as pipes and coils, forming processing is still required.

[0003] In existing technologies, copper alloy tubes are prefabricated into various shapes, including a circular copper alloy tube on the left and two semi-circular copper alloy tubes on the right. During use, the two semi-circular copper alloy tubes can be inserted into the same circular copper alloy tube. However, this design requires prefabrication of the semi-circular copper tubes. In isolated applications such as ships, when semi-circular tubes are needed, on-site fabrication is required. Therefore, the inventor provides a processing device and method for seamless copper alloy tubes for marine applications. Summary of the Invention

A limiting cavity for positioning a circular copper alloy tube is formed between the two limiting semi-rings. An expansion cavity for expanding the circular copper alloy tube is formed on the inner wall of the limiting cavity near the molded semi-ring. Two mounting semi-rings are detachably connected within the limiting cavity. Locking blocks are provided on both sides of the limiting semi-rings, and locking cavities are formed on the locking blocks. A locking stop is provided on the side of the limiting semi-ring near the molded semi-ring. Multiple locking inserts that insert into the locking cavities are provided on the side of the locking stop near the locking block. These locking inserts are used for locking. Two limiting semi-rings are defined; a first connecting rod is hinged to the limiting semi-ring, and a second connecting rod is rotatably connected to the first connecting rod. The end of the second connecting rod away from the first connecting rod is rotatably connected to the shaping semi-ring. A pressing semi-ring is detachably connected to the shaping semi-ring. A shaping socket or limiting socket is provided on the side of the locking block near the shaping semi-ring. When the shaping semi-ring abuts against the limiting semi-ring, the shaping semi-ring is used to expand the annular copper alloy tube. Two forming cavities are formed between the two shaping semi-rings and the shaping socket. The forming cavities are used to press the semi-circular copper alloy tube.

[0006] By adopting the above technical solution, during use, the circular copper alloy tube is fixed by a limiting semi-ring, and the shaped semi-ring cooperates with the limiting socket to expand the circular copper alloy tube. The shaped semi-ring and the shaped socket can be used to process semi-circular copper alloy tubes, and the two processed semi-circular copper alloy tubes are inserted into the expanded circular copper alloy tube. This design improves the convenience of processing copper alloy tubes and makes it easier to connect copper alloy pipelines.

[0007] Preferably, the outer wall of the mounting semi-ring is provided with a first positioning block, the inner wall of the limiting cavity is provided with a first positioning groove that is inserted and cooperates with the first positioning block, the outer wall of the pressing semi-ring is provided with a second positioning block, and the inner wall of the shaping semi-ring is provided with a second positioning groove that is inserted and cooperates with the second positioning block.

[0008] By adopting the above technical solution, the first positioning block and the second positioning block can more stably restrict the installation half ring and the pressing half ring, thereby improving the stability of the installation half ring and the pressing half ring; it can process circular copper alloy tubes of various sizes, thereby improving the convenience of copper alloy tube processing in isolated environments such as ships.

[0009] Preferably, a guide ring is provided at one end of the pressing half-ring near the limiting half-ring, and the inner diameter of the guide ring gradually decreases along the direction near the limiting half-ring.

[0010] By adopting the above technical solution, during use, the end of the pressed semi-circular copper alloy tube can be recessed inward, which makes it easier to insert the copper alloy tube into the circular copper alloy tube and improves the convenience of copper alloy tube connection.

[0011] Preferably, the shaped semi-ring has a limiting cavity that slides and cooperates with the locking block.

[0012] By adopting the above technical solution, the limiting slide cavity and the limiting stop block work together, which allows the shaped semi-ring to slide more smoothly and improves the stability of the shaped semi-ring pressing the circular copper alloy tube.

[0013] Preferably, an expansion socket is fixed on the side of the locking block near the locking block. The expansion socket has a limiting slot that engages with the semi-circular copper alloy tube. Two expansion ramps are formed on the expansion socket. The shaped semi-ring abuts against the expansion ramps and presses the semi-circular copper alloy tube. A contraction cavity is formed on the inner wall of the limiting cavity. The contraction cavity is arranged opposite to the shaped semi-ring.

[0014] By adopting the above technical solution, during use, a semi-circular copper alloy tube is inserted into a circular copper alloy tube, the expansion socket is installed and fixed, and then the shaped semi-ring is abutted against the expansion inclined surface, thereby squeezing the copper alloy tube towards the shrinkage cavity. This allows the circular copper alloy tube and the semi-circular copper alloy tube to be connected more firmly, improving the processing effect of the copper alloy tube.

[0015] Preferably, a guide block is provided on the side of the expansion socket away from the limiting semi-ring, and the thickness of the guide block gradually decreases in the direction away from the limiting semi-ring. The guide block is used to guide the shaping semi-ring.

[0016] By adopting the above technical solution, the use of guide blocks can make the molding half-rings easier to insert, thus improving the smoothness of the molding half-rings in use.

[0017] Preferably, the extension socket has two extrusion blocks on the side away from the shaped semi-ring, and the two extrusion blocks are used to extrude the end of the semi-circular copper alloy tube.

[0018] By adopting the above technical solution, during use, the shaped semi-ring is extruded and expanded with an inclined surface, which allows the extrusion block to press the semi-circular copper alloy tube tightly. Under the action of the two extrusion blocks, the sides of the two semi-circular copper alloy tubes that are close to each other can be squeezed and deformed, thereby allowing the liquid inside the copper alloy tube to flow more smoothly and improving the convenience of using the copper alloy tube.

[0019] Preferably, a cylindrical insert is inserted into one end of the semi-circular copper alloy tube away from the limiting semi-ring. The cylindrical insert has an installation hole for the shaping semi-ring on the side away from the limiting semi-ring. The shaping semi-ring presses the cylindrical insert to expand the semi-circular copper alloy tube.

[0020] By adopting the above technical solution, during use, the cylindrical shape of the semi-circular copper alloy tube can be better ensured to be far away from the limiting semi-ring, and the semi-circular copper alloy tube can be bent, thus facilitating subsequent installation and use.

[0021] Preferably, the outer diameter of the cylindrical insert gradually decreases along the direction close to the limiting semi-ring.

[0022] By adopting the above technical solution, semi-circular copper alloy tubes can be pressed more effectively.

[0026] The following is in conjunction with the appendix Figure 1 - Figure 8 This application will be described in further detail.

[0027] This application discloses a processing apparatus and method for seamless copper alloy pipe fittings for marine applications.

[0028] Example 1; Reference Figure 1A seamless copper alloy pipe fitting processing device for marine applications includes two hinged limiting semi-rings 1 and two abutting shaping semi-rings 7. Both the limiting semi-rings 1 and the shaping semi-rings 7 are C-shaped. A limiting cavity 11 for positioning a circular copper alloy pipe 9 is formed between the two limiting semi-rings 1. An expansion cavity 12 for expanding the circular copper alloy pipe 9 is formed on the inner wall of the limiting cavity 11 near the shaping semi-rings 7. The expansion cavity 12 is circular and provides space for the deformation of the copper alloy pipe. Two mounting semi-rings 14 are detachably connected inside the limiting cavity 11. By replacing the mounting semi-rings 14, various sizes of circular copper alloy pipes 9 can be accommodated, improving the convenience of fixing the copper alloy pipe. Locking blocks 2 are fixed on both sides of the limiting semi-rings 1. The locking blocks 2 are rectangular blocks, and the locking blocks 2 on the two limiting semi-rings 1 abut against each other, allowing the two limiting semi-rings 1 to be more stably abutted and fixed. Locking cavities are formed on the locking blocks 2, which are rectangular cavities. A locking block 3 is fixed to the side of the limiting semi-ring 1 near the shaping semi-ring 7. The locking block 3 is a rectangular block, and multiple locking inserts that engage with the locking cavity are integrally formed on the side of the locking block 3 near the locking block 2. The locking inserts are used to lock the two limiting semi-rings 1. A first connecting rod 5 is hinged to the limiting semi-ring 1, and a second connecting rod 6 is rotatably connected to the first connecting rod 5. The end of the second connecting rod 6 away from the first connecting rod 5 is rotatably connected to the shaping semi-ring 7. A pressed semi-ring 17 is detachably connected to the shaping semi-ring 7. The pressed semi-ring 17 can be adapted to various sizes of semi-circular copper alloy tubes 10, improving the convenience of using copper alloy tubes. A shaping socket 8 or a limiting socket 25 is fixed to the side of the locking block 3 near the shaping semi-ring 7. Changing the shaping socket 8 or the limiting socket 25 improves the convenience of using the processing device. When the shaped semi-ring 7 abuts against the limiting semi-ring 1, the shaped semi-ring 7 is used to expand the circular copper alloy tube 9. Two forming cavities 13 are formed between the two shaped semi-rings 7 and the shaped socket 8. The forming cavities 13 are used to press the semi-circular copper alloy tube 10.

[0029] The outer wall of the mounting half-ring 14 is fixed with a first positioning block 23, and the inner wall of the limiting cavity 11 is provided with a first positioning groove 24 that is inserted and engaged with the first positioning block 23. The outer wall of the pressed half-ring 17 is fixed with a second positioning block 27, and the inner wall of the shaped half-ring 7 is provided with a second positioning groove 26 that is inserted and engaged with the second positioning block 27. This makes it easier to install the mounting half-ring 14 and the pressed half-ring 17.

[0030] A guide ring 16 is integrally formed at one end of the pressed semi-ring 17 near the limiting semi-ring 1, and the inner diameter of the guide ring 16 gradually decreases along the direction near the limiting semi-ring 1. The outer wall of the shaped semi-ring 7 gradually decreases along the direction near the limiting semi-ring 1. A limiting slide cavity 4 is provided on the shaped semi-ring 7 to slide and cooperate with the locking stop 3.

[0031] The implementation principle of the seamless copper alloy pipe processing device for marine applications according to this application is as follows: During use, a circular copper alloy pipe 9 is fixed by a limiting semi-ring 1. A shaping semi-ring 7 cooperates with a limiting socket 25 to expand the circular copper alloy pipe 9. The shaping semi-ring 7 cooperates with a shaping socket 8 to process a semi-circular copper alloy pipe. The two processed semi-circular copper alloy pipes are then inserted into the expanded circular copper alloy pipe 9. This design improves the convenience of processing copper alloy pipes and allows for easier connection of copper alloy pipelines.

[0032] Example 2; Reference Figure 6 The difference between this embodiment and embodiment 1 is that an extension socket 19 is fixed on the side of the locking block 3 near the locking block 2. The extension socket 19 has a limiting slot 28 that is inserted and matched with the semi-circular copper alloy tube 10. Two extension inclined surfaces 20 are formed on the extension socket 19. The shaped semi-ring 7 abuts against the extension inclined surface 20 and presses the semi-circular copper alloy tube 10. A shrinkage cavity 15 is formed on the inner wall of the limiting cavity 11. The shrinkage cavity 15 is arranged opposite to the shaped semi-ring 7, so that the annular copper alloy tube 9 and the semi-circular copper alloy tube 10 can be squeezed, thereby improving the convenience of copper alloy tube connection.

[0033] The extension socket 19 has a guide block 29 integrally formed on the side away from the limiting semi-ring 1. The thickness of the guide block 29 gradually decreases in the direction away from the limiting semi-ring 1. The guide block 29 is used to guide the shaping semi-ring 7.

[0034] Two extrusion blocks 18 are fixed to the side of the extension socket 19 away from the shaped semi-ring 7. The two extrusion blocks 18 are used to extrude the end of the semi-circular copper alloy tube 10. This reduces the resistance to fluid flow inside the copper alloy tube.

[0035] A cylindrical insert 21 is inserted into one end of the semi-circular copper alloy tube 10 away from the limiting semi-ring 1. The cylindrical insert 21 has an installation hole 22 for the molding semi-ring 7 on the side away from the limiting semi-ring 1. The molding semi-ring 7 presses the cylindrical insert 21 to expand the semi-circular copper alloy tube 10. The outer diameter of the cylindrical insert 21 gradually decreases along the direction close to the limiting semi-ring 1.

[0036] The implementation principle of Example 2 is as follows: During use, the semi-circular copper alloy tube 10 is inserted into the annular copper alloy tube 9, the expansion socket 19 is installed and fixed, and the shaped semi-ring 7 is abutted against the expansion inclined surface 20, so that the extruded copper alloy tube can be squeezed closer to the shrinkage cavity 15, thereby making the annular copper alloy tube 9 and the semi-circular copper alloy tube 10 more firmly connected and improving the processing effect of copper alloy tube.

[0037] A method for processing seamless copper alloy tubular fittings for marine applications, comprising the following specific steps; First, positioning: place the annular copper alloy tube 9 into the limiting cavity 11, press and fix the annular copper alloy tube 9 with two limiting half rings 1, and fix and install half rings 14 according to the size of the annular copper alloy tube 9 of different sizes. Second, limit the movement by inserting the locking block 3 with the molded socket 8 into the locking cavity; Third, expansion: the staff presses the second connecting rod 6 and pushes the shaped semi-ring 7 into the circular copper alloy tube 9; Fourth, replace the molded socket 8 with the limiting half-ring 1; Fifth, pressing: the staff presses the second connecting rod 6, and the shaping semi-ring 7 cooperates with the limiting semi-ring 1 to press the semi-circular copper alloy tube 10. The size of the pressing semi-ring 17 is adjusted according to the size of the semi-circular copper alloy tube 10. Sixth, insertion: insert the two pressed semi-circular copper alloy tubes 10 into the annular copper alloy tube 9; Seventh, welding: use a welding machine to weld the semi-circular copper alloy tube 10 to the annular copper alloy tube 9.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
