[0002] Copper-chromium-nickel-silicon alloy is a high-performance copper-based material, suitable for application scenarios requiring excellent electrical conductivity, corrosion resistance and high strength. To ensure the best performance of this alloy, its hot working treatment process is crucial, which includes steps such as melting and forging, solution treatment, and subsequent final forming and surface finishing.

[0003] In the common forming and surface treatment process of copper-chromium-nickel-silicon alloy, the copper-chromium-nickel-silicon alloy is first fixed on a dedicated device, and then the device is used to precisely process the inside and outside of the copper-chromium-nickel-silicon alloy to achieve the required dimensional accuracy. In addition, features such as holes, grooves or threads are cut on the surface of the copper-chromium-nickel-silicon alloy. Finally, the copper-chromium-nickel-silicon alloy is installed on a polishing machine for surface polishing and a protective coating may be applied to improve the aesthetics and durability of the copper-chromium-nickel-silicon alloy.

[0004] Although the existing technology can meet certain processing quality standards, there are still some problems in actual operation. When performing various different types of processing, it is often necessary to switch different dedicated devices, such as lathes, grinders, etc., which leads to frequent loading and unloading operations, increasing the production cycle time.

Detailed implementation manners

[0045] The following further elaborates on this application Figures 1-15 in conjunction with the appended drawings.

[0046] Please refer to Figure 1 , Figure 2 , Figure 4 , Figure 14 and Figure 15 , a hot working treatment process for copper-chromium-nickel-silicon alloy, comprising the following steps:

[0047] S1. Melting and casting: First, pure copper and other alloying elements such as chromium, nickel, silicon, etc. are mixed in a predetermined ratio and melted at high temperature; then the molten metal is poured into a pre-prepared mold for casting to obtain a casting.

[0048] S2. Homogenization treatment: The casting is heated at a certain temperature for a long time and then slowly cooled. Through the above homogenization treatment, composition segregation and microstructural non-uniformity are eliminated.

[0049] S3. Hot rolling treatment: The casting after homogenization treatment is hot rolled to form the required shape and size. The hot working temperature should be controlled within a suitable range to ensure that the material has good plasticity and fluidity.

[0050] S4. Solution treatment: The casting is heated to a temperature close to but lower than the melting point of the alloy, held for a period of time and then rapidly cooled. The purpose is to fully dissolve the alloying elements into the matrix and improve the hardness and strength of the material.

[0051] S5. Aging treatment: The casting after solution treatment is placed at a low temperature and held for a period of time to promote the formation of precipitation phases, thereby improving the mechanical properties of the alloy.

[0052] S6. Final processing and surface treatment: First, place several alloys into an alloy grinding device. Immediately start the alloy grinding and cutting device, and use the inner support method to drive the rotation of several alloys. During the rotation process, perform the cutting work on the external threads of the alloy, and cooperate with the clamping and fixing of the alloy outer wall to complete the grinding work on the inner wall of the alloy.

[0053] The above step S6 is completed in cooperation with a copper-chromium-nickel-silicon alloy hot processing device, which specifically includes an annular housing 1. The lower end of the annular housing 1 is open, and the upper end of the annular housing 1 is sealed. An actuator 2 for processing the alloy is provided inside the annular housing 1. An adjustment mechanism 3 for cooperating with the processing part 22 to interchange the inner support and inner grinding is provided on the annular housing 1. A cover 4 for containing the alloy and sealing the annular housing 1 into a whole is installed on the lower end surface of the annular housing 1. A support part 5 is also installed on the outer wall of the annular housing 1.

[0054] Please refer to Figure 8 , the actuator 2 includes five support circular plates 21 rotatably arranged in a circumferential array inside the annular housing 1. Processing parts 22 for inner support and inner grinding of the alloy are provided on all five support circular plates 21. Above the processing part 22, a driving part 23 for controlling the operation of the processing part 22 is provided.

[0055] During specific operation, first place several alloys on the cover 4, and then the cover 4 drives the alloys placed thereon upward and moves them into the annular housing 1. Subsequently, the annular housing 1 is sealed into a whole through the cover 4. Immediately, the driving part 23 drives the processing part 22 to perform the inner support work on the alloy. While performing the inner support work, the outer wall of the alloy is cut by the driving part 23. After the cutting is completed, start the adjustment mechanism 3, and complete the grinding work on the inside of the alloy through the cooperation between the adjustment mechanism 3 and the processing part 22. Finally, after the cutting and grinding work are completed, remove the cover 4 and replace it with new alloys for processing.

[0056] Please refer to Figure 1 and Figure 14, the described support part 5 includes an annular bearing platform 51 fixedly arranged on the outer wall of the annular housing 1. On the outer wall of the annular bearing platform 51, a number of U-shaped frames 52 distributed in the circumferential direction are fixedly arranged. At the central positions of the upper end faces of the number of U-shaped frames 52, a first telescopic push rod 53 is fixedly arranged in common. On the side walls of the number of U-shaped frames 52 close to each other, sliding grooves 521 are opened. The cover 4 is slidably arranged inside the corresponding sliding grooves 521 through a number of sliding blocks. At the central positions of the lower end faces of the number of U-shaped frames 52, a multi-stage second telescopic push rod 54 is fixedly arranged in common. The first-stage telescopic section of the second telescopic push rod 54 is fixedly connected with the cover 4 through a connecting frame 55.

[0057] Please refer to Figure 3 , Figure 7 and Figure 11 , at the positions corresponding to two adjacent support circular plates 21 on the upper end face of the annular housing 1, rectangular through grooves 11 are opened. At the central position of the upper end face of the annular housing 1, an avoidance through groove is also opened. On the lower end face of the annular housing 1, five hexagonal limiting grooves 13 are opened upward in a circumferential array manner. On the lower end face of the support circular plate 21, six sliding grooves 211 are opened in a circumferential array manner. On the lower end face of the support circular plate 21, a cylindrical housing 212 is fixedly arranged. On the outer wall of the cylindrical housing 212, mounting grooves 213 are opened corresponding to the six sliding grooves 211.

[0058] Please refer to Figure 3 and Figure 5 , the cross-section of the cover 4 is U-shaped. At the positions corresponding to the five hexagonal limiting grooves 13 on the upper end face of the higher part of the cover 4, hexagonal limiting columns 41 with electromagnets on the outer walls are fixedly arranged. On the upper end face of the lower part of the cover 4, a number of support platforms 42 for supporting the alloy are fixedly arranged in a circumferential array manner. At the central position of the support platform 42, a circular through groove penetrating the support platform 42 and the cover 4 is opened downward. On the cover 4, a cooperation group 43 for cooperating with the processing part 22 to work is also installed.

[0059] Please refer to Figure 11 and Figure 12 , the described processing part 22 includes arc-shaped supporting blocks 221 slidably arranged inside the six mounting grooves 213. The lower end faces of the arc-shaped supporting blocks 221 are slidably arranged in the corresponding sliding grooves 211 through circular rods respectively. The processing part 22 also includes a number of teeth 222 fixedly arranged on the outer wall of the support circular plate 21 in a circumferential array manner. The arc-shaped supporting blocks 221 are used for supporting the inner wall of the alloy and performing inner grinding work. Chamfers are arranged at the ends of the lower end faces of the six arc-shaped supporting blocks 221 close to each other.

[0060] Please refer to Figure 4 , Figure 5 , Figure 6 and Figure 14, the mating group 43 includes a tapered plug 431 that mates with the inclined surface of the arc-shaped bearing block 221. There are five tapered plugs 431, which slide inside the circular through groove respectively. The lower end surface of the tapered plug 431 is rotatably connected to a second annular plate 432 through a round rod. Five connecting plates 433 are fixedly arranged on the inner side wall of the second annular plate 432 in a circumferential array. The closer ends of the five connecting plates 433 are fixedly connected together to form a disc 434. The disc 434 is fixedly connected to the secondary telescopic section of the telescopic push rod 54.

[0061] Place five alloys on the corresponding supporting platforms 42, and then control the telescopic push rod 54 to extend. At the same time, the primary telescopic section of the telescopic push rod 54 drives the cover 4 to move upward synchronously with the five alloys, and makes the hexagonal limit posts 41 move into the corresponding hexagonal limit grooves 13. At this time, the five alloys are respectively sleeved on the outer walls of the corresponding cylindrical shells 212. Then, turn on the power supply of the electromagnet on the hexagonal limit posts 41 to seal the annular shell 1 and the cover 4 into a whole. Thus, the preliminary preparation work for alloy processing is completed.

[0062] After the alloy is inside the annular shell 1, control the secondary telescopic section of the telescopic push rod 54 to extend. At this time, the second annular plate 432 moves upward synchronously under the drive of the connecting plates 433. When the second annular plate 432 moves upward, the tapered plugs 431 arranged thereon respectively cooperate with the arc-shaped bearing blocks 221 upward, so that the six arc-shaped bearing blocks 221 expand along the corresponding sliding grooves 211 and mounting grooves 213 and contact the inner wall of the alloy. As the secondary telescopic section of the telescopic push rod 54 gradually extends, the arc-shaped bearing blocks 221 also gradually press against the inner wall of the alloy. Thus, the positioning work before alloy cutting is completed.

[0063] Please refer to Figure 8 and Figure 10 , the driving part 23 includes a driving motor 231 fixedly arranged on the upper end surface of the annular shell 1. The output shaft of the driving motor 231 passes through the avoidance through groove, and a driving gear 232 that always meshes with the teeth 222 on the support circular plate 21 is fixedly arranged at the lower end of the output shaft of the driving motor 231. The driving part 23 also includes a cutting group 233 arranged below the driving gear 232 for processing the outer wall of the alloy.

[0064] Please refer to Figure 9 、 Figure 12 and Figure 13, the cutting group 233 includes a circular column 2331 fixedly arranged on the lower end face of the driving gear 232. Helical grooves with opposite helix directions are respectively formed on the outer walls of the upper and lower ends of the circular column 2331. Three annular mounting blocks 2332 are distributed on the outer wall of the circular column 2331 in the up and down direction. The upper and lower annular mounting blocks 2332 are respectively threadedly connected to the corresponding threaded grooves, and rectangular blocks 2333 with cavities inside are fixedly arranged on the outer walls of the upper and lower annular mounting blocks 2332 corresponding to the positions of the five support circular plates 21. A cutting tool 2334 is slidably arranged in the cavity inside the rectangular block 2333 through a spring. The cutting edge of the cutting tool 2334 is mounted on the side away from the annular mounting block 2332, and the non-cutting-edge side of the cutting tool 2334 is set as an inclined surface.

[0065] Please refer to Figure 12 , the driving group further includes a strip-shaped block 2335 fixedly arranged on the outer wall of the middle annular mounting block 2332. There are five strip-shaped blocks 2335 which are respectively located between the upper and lower rectangular blocks 2333. The upper and lower ends of the strip-shaped block 2335 are set as hypotenuses which are in fit with the inclined surfaces of the cutting tool 2334 and respectively slide through the corresponding rectangular blocks 2333. Two locking grooves 2336 distributed in the up and down direction are further formed on the side wall of the strip-shaped block 2335.

[0066] After the alloy completes the locking work, start the driving motor 231 to drive the driving gear 232 to engage with the teeth 222 of the five support circular plates 21. At this time, the alloy located on the support circular plates 21 rotates synchronously with the support circular plates 21 under the pressing of the arc-shaped supporting blocks 221. At the same time, when the driving gear 232 rotates, it drives the circular column 2331 on its lower end face to rotate. When the circular column 2331 rotates, the annular mounting blocks 2332 and the rectangular blocks 2333 arranged at its upper and lower ends approach synchronously along the helical grooves. When the upper and lower rectangular blocks 2333 approach synchronously, the inclined surfaces of the cutting tools 2334 arranged inside them are in contact and fit with the inclined surfaces of the strip-shaped block 2335, so that the cutting tools 2334 extend out of the rectangular blocks 2333 and abut against the outer wall of the alloy. The cutting work of the external thread of the alloy is completed through the synchronous approach of the upper and lower cutting tools 2334 and the rotation of the alloy.

[0067] As the driving motor 231 drives the continuous rotation of the driving gear 232, when the upper and lower cutting tools 2334 approach synchronously and move into the locking grooves 2336 on the side wall of the strip-shaped block 2335, the springs on the cutting tools 2334 quickly reset and pull the cutting edges of the cutting tools 2334 away from the outer wall of the alloy through the rebounding force, thereby completing the tool withdrawal work of cutting the external thread.

[0068] Please refer to Figure 1 , Figure 3 and Figure 9The adjusting mechanism 3 includes a wedge block 31, five of which are provided and are slidably arranged inside the rectangular through groove 11 respectively. The upper end surfaces of the five wedge blocks 31 are fixedly provided with a ring plate 32. A circular base 33 with a cavity inside is installed at the center position of the ring plate 32. The circular base 33 is located directly above the driving motor 231 and is fixedly connected to the telescopic section of the telescopic push rod 53. The circumferential outer wall of the circular base 33 is fixedly provided with five connecting plates 34 fixedly connected to the ring plate 32.

[0069] Please refer to Figure 4 、 Figure 8 and Figure 9 The adjustment mechanism 3 also includes five engaging groups that are rotatably arranged on the inner wall of the annular shell 1 through a roller shaft (not shown in the drawings). The five engaging groups are respectively arranged between two adjacent supporting circular plates 21. Each engaging group includes two clamping blocks 35 that are in contact with the outer wall of the alloy. The two adjacent sides of the clamping blocks 35 are both provided with an inclined surface facing downward, and the wedge block 31 is located between the inclined surfaces of the two clamping blocks 35.

[0070] When the external thread cutting of the alloy is completed, first control the secondary telescopic section of the telescopic push rod 2 54 to drive the annular plate 2 432 and several conical plugs 431 to move downward, and then control the telescopic push rod 1 53 to push the annular plate 1 32 and the wedge block 31 to move downward. At this time, the wedge block 31 cooperates with the inclined surfaces on both sides and the inclined surfaces of the clamping block 35, so that the two clamping blocks 35 slide along the annular shell 1 and hold and fix the outer wall of the alloy.

[0071] Next, when the outer wall of the alloy is clamped and fixed, the secondary telescopic section of the telescopic push rod 254 is controlled to drive the conical plug 431 to move upward and drive the corresponding arc-shaped support block 221 to slide along the installation groove 213 and the sliding groove 211. At this time, the arc-shaped support block 221 completes the resistance work against the inside of the alloy, and then starts the drive motor 231 to drive the active gear 232 and the driven gear to rotate. Since the outer wall of the alloy is clamped and fixed, the support circular plate 21 can only drive the arc-shaped support block 221 to rotate and realize the grinding work on the inner wall of the alloy when it rotates.

[0072] Finally, when the inner wall of the alloy is polished, the secondary telescopic sections of the telescopic push rod 1 53 and the telescopic push rod 2 54 are controlled to reset, and then the power supply of the electromagnet on the hexagonal limit column 41 is disconnected and the first telescopic section of the telescopic push rod 2 54 is retracted to drive the cover 4 away from the annular shell 1, and then the cutting waste on the cover 4 is cleaned and replaced with new alloy for the next processing.
