Description

Technical Field

[0001] This invention relates to the field of metal powder processing technology, and in particular to a production equipment for manufacturing copper-tungsten-brass contacts for high-voltage switches. Background Technology

[0002] Copper-tungsten alloys are widely used as contact materials for high-voltage switches due to their good resistance to arc erosion, resistance to welding, and high strength. The copper-tungsten component is mainly prepared by powder metallurgy, which involves mixing and pressing tungsten powder and copper powder, followed by sintering. In the powder metallurgy production of copper-tungsten-brass contacts, existing technologies typically use pressure equipment to press the mixed metal powder placed in upper and lower molds.

[0003] For example, Chinese patent application number CN202411194445.8 discloses a copper-tungsten alloy electrical contact production equipment, including a support frame, guide rail I, lower mold, connecting frame I, etc. It allows for easy replacement of the lower and upper molds by pre-placing the required replacement molds into guide rails I and II, and then automatically releasing the limits and obstructions on the lower and upper molds through limiting and blocking mechanisms. This simplifies the operation and saves time and effort. However, this production equipment can only form single-component compacts. The large density difference between copper-tungsten and brass mixed powders easily leads to particle stratification, voids, and uneven distribution, making it impossible to achieve gradient composition molding of copper-tungsten-brass composite contacts. This makes it difficult to match the performance requirements of high copper-tungsten content in the working area and high brass content in the base area of ​​the contact, and thus cannot meet the stringent operating requirements of ultra-high voltage and extra-high voltage switches. Summary of the Invention

[0004] In view of this, the purpose of this invention is to provide a production equipment for manufacturing copper-tungsten-brass contacts for high-voltage switches, in order to solve the technical problems of existing technology which can only form single-component compacts, while the large difference in particle density between copper-tungsten and brass mixed powders makes it easy for particles to separate, accumulate voids, and have uneven distribution. This makes it impossible to achieve gradient composition molding of copper-tungsten-brass composite contacts, and it is difficult to match the performance requirements of high copper-tungsten content in the working area of ​​the contact and high brass content in the base area, thus failing to meet the stringent operating conditions of ultra-high voltage and extra-high voltage switches.

[0005] To achieve the above objectives, the present invention provides a production equipment for manufacturing copper-tungsten-brass contacts for high-voltage switches, comprising a frame and a sliding frame mounted on the frame.

[0019] The base is located at the lower end of the support rod, and the mold is hinged to the base by a flipping block.

[0020] Furthermore, the base has fitting seats evenly distributed around the inner side of the support frame, the fitting seats are in contact with the lower side surface of the mold, and the side ends of the fitting seats are provided with water grooves.

[0021] Furthermore, the vibration assembly includes:

[0027] Vibrating balls, which are circumferentially distributed around the inner side of the rotating cover by an elastic element, can press against the flipping block.

[0028] Furthermore, the elastic element is a spring, and a plurality of sliding rods are circumferentially slidable on the rotating cover.

[0049] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0050] It should be noted that, unless otherwise defined, the technical or scientific terms used in this invention should have the ordinary meaning understood by one of ordinary skill in the art to which this invention pertains.

Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0051] The first aspect of this invention provides a production apparatus for manufacturing copper-tungsten-brass contacts for high-voltage switches, such as... Figure 1-9 As shown, the equipment includes a frame 1 and a sliding frame 2 mounted on the frame 1. The lower part of the sliding frame 2 is equipped with a mold 3 for holding copper-tungsten-brass mixed powder. There are several molds 3, all of which are flexible structures and are modular. The production equipment also includes:

[0052] High-pressure vessel 4 is mounted on frame 1;

[0053] A sealing cover 5 is provided on the sliding frame 2, and the sealing cover 5 can close the top of the high pressure vessel 4;

[0054] A mounting assembly coaxially located at the lower end of the sealing cover 5 is used to mount several molds 3;

[0055] The support frame 6 is installed inside the frame 1;

[0056] A vibration assembly mounted on the support frame 6 is used to fill the mold 3 with copper-tungsten-brass mixed powder;

[0057] A drive assembly used to drive the sliding frame 2 to perform lifting and moving actions.

[0058] In this embodiment, when in use, a suitable flexible split mold 3 is selected according to the specifications of the high voltage switch contact to be processed. After the split mold 3 is precisely assembled, it is rotated upward and fixedly installed on the mounting assembly. Under normal molding conditions, mixed powder is filled into the cavity of the mold 3. Under gradient molding conditions, high copper tungsten powder and high brass powder are filled into the cavity.

[0059] When the filling state is reached, the sliding frame 2 is at the low point. At this time, the installation component is placed within the range of the vibration component. Simultaneously, the vibration component is activated to make the mold 3 generate high-frequency micro-vibration, so as to realize the rapid and uniform filling and compaction of powder, and eliminate voids and delamination defects.

[0060] Then, the mold 3 is sealed, the drive assembly is activated to raise the sliding frame 2 and move it horizontally to the top of the high pressure container 4. The drive assembly then drives the sliding frame 2 to descend, so that the mold 3 is placed into the high pressure container 4. At the same time, the sealing cover 5 is precisely fastened to the top of the high pressure container 4, so that the high pressure container 4 is completely sealed. The liquid medium in the high pressure container 4 applies pressure evenly to the mold 3 from all directions. A hydrostatic pressure of 200MPa is applied and the pressure is maintained for 10 minutes, so that the metal mixed powder is isotropically densified.

[0061] After the forming process is completed, the sealing cover 5 is opened to move the sliding frame 2 out of the high-pressure container 4, the split mold 3 is opened to collect the formed green blank, and it is transferred to the next sintering station.

[0062] In this embodiment, as Figure 2 As shown, the split-structure mold 3 includes a first sleeve 7 and a second sleeve 8, which can be combined. The first sleeve 7 is provided with a first pipe 9, and the second sleeve 8 is provided with a second pipe 10. The first pipe 9 and the second pipe 10 extend into the inner cavity after the first sleeve 7 and the second sleeve 8 are combined. The top of the first pipe 9 and the second pipe 10 are provided with a sealing plug 11. The split-structure of the first sleeve 7 and the second sleeve 8 can effectively avoid the problems of molded blank jamming, bumping deformation and breakage. At the same time, the first pipe 9 and the second pipe 10 can realize bidirectional feeding and bidirectional venting. During the filling process, the air in the inner cavity of the mold 3 can be quickly discharged to avoid air retention and the formation of powder voids, further improving the powder filling density.

[0063] In this embodiment, as Figure 3As shown, the split-structure mold 3 includes a first sleeve 7 and a second sleeve 8, which can be combined. Both the first sleeve 7 and the second sleeve 8 have a diaphragm 12 inside, which divides the inner cavity of the combined mold 3 into an inner filling area 13 and a middle filling area 14. The first sleeve 7 has a first pipe 9 extending to the inner filling area 13, and the second sleeve 8 has a second pipe 10 extending to the middle filling area 14. Both the first pipe 9 and the second pipe 10 have a sealing plug 11 at the top.

[0064] It should be noted that the diaphragm 12 is preferably a 0.05mm thick water-soluble PVA film, which can be completely decomposed in the early stage of subsequent sintering to ensure the metallurgical bonding of the interface. Copper powder or high copper content copper-tungsten powder is injected into the internal filling area 13 through pipe 19; high tungsten content copper-tungsten powder is injected into the central filling area 14 through pipe 210. The diaphragm 12 physically isolates the powders of different components to create a component gradient effect, so that the formed contact can achieve a gradient component distribution of high copper-tungsten at the working end and high brass at the base end, matching the differentiated performance requirements of the ablation-resistant working area and the high conductivity base area of ​​the high voltage switch contact.

[0065] In this embodiment, as Figure 4 , Figure 5 As shown, the installation components include:

[0066] The central shaft 15 is coaxially located at the lower end of the sealing cover 5;

[0067] Positioning bracket 16 located at the lower end of the central axis 15;

[0068] The clamping head 17 is circumferentially arranged on the positioning frame 16. The middle part of the mold 3 has a stepped structure, and the clamping head 17 engages with the stepped structure in the middle of the mold 3.

[0069] The support rod 18, which is mounted on the positioning frame 16, can be adjusted by bolts.

[0070] The base 19 is located at the lower end of the support rod 18. The mold 3 is hinged to the base 19 via the flipping block 20 to ensure that the multiple molds are circumferentially uniform and coaxially aligned. Under multi-station molding conditions, the molding pressure, vibration amplitude, and filling conditions of each mold are completely consistent, ensuring that the performance of batch products is highly consistent. The clamping head 17 engages with the stepped structure of the mold 3 for positioning, enabling quick disassembly and precise positioning of the mold 3. The bolt-adjustable support rod 18 can be adapted to contact molds of different heights and specifications without replacing the overall installation components. The hinge structure at the flipping block 20 allows the mold 3 to rotate downwards after molding and the detachable split mold 3 facilitates quick demolding of the internal formed blank.

[0071] In this embodiment, as Figure 4 , Figure 5As shown, the base 19 has fitting seats 21 evenly distributed around the inner side of the support frame 6. The fitting seats 21 are in contact with the lower side surface of the mold 3. The side ends of the fitting seats 21 are provided with water channels. The fitting seats 21 fit and limit the lower part of the mold 3 in all directions, further ensuring the stability of the mold 3. When the high pressure container 4 is filled with liquid medium, the water channels on the fitting seats 21 allow the liquid medium to flow through the water channels, ensuring that the liquid medium can act evenly on the entire outer surface of the mold 3, and realize the uniform transmission of isotropic pressure.

[0072] In this embodiment, as Figure 6 , Figure 7 As shown, the vibration assembly includes:

[0073] The drive motor 22 is mounted on the support frame 6;

[0074] The drive wheel 23 is mounted on the drive motor 22;

[0075] An inverted bracket 24 is mounted on the support frame 6;

[0076] A driven wheel 25 is mounted on a U-shaped frame 24, and the driven wheel 25 meshes with the driving wheel 23;

[0077] A rotating cover 26 is coaxially mounted on the driven wheel 25, and the mold 3 can be placed inside the rotating cover 26;

[0078] Vibrating balls 27, which are circumferentially distributed on the inner side of the rotating cover 26 via elastic elements, can press against the flipping block 20.

[0079] Specifically, the output of the drive motor 22 drives the drive wheel 23 to rotate, the drive wheel 23 drives the driven wheel 25 to rotate, and the driven wheel 25 drives the rotating cover 26 to rotate. When the rotating cover 26 rotates, the vibrating ball 27 collides with the flipping block 20 through the elastic element, generating vibration impact. As the rotating cover 26 continues to rotate, the vibrating ball 27 periodically hits each flipping block 20, causing the mold 3 to generate high-frequency micro-amplitude vibration, thereby promoting the flow and dense filling of powder in the mold 3.

[0080] In this embodiment, as Figure 7 As shown, the elastic element is a spring 28. Several sliding rods 29 are circumferentially slidable on the rotating cover 26. The vibrating ball 27 is located at the end of the sliding rod 29. The spring 28 is sleeved on the sliding rod 29. One end of the spring 28 abuts against the inner side wall of the rotating cover 26, and the other end of the spring 28 abuts against the vibrating ball 27. The elastic restoring force of the spring 28 can ensure that the vibrating ball 27 continuously and stably outputs vibration energy. The vibration amplitude is uniform and controllable, and the vibration effect can be adaptively adjusted according to different powder particle sizes and filling thicknesses.

[0081] In this embodiment, as Figure 8 As shown, the driving component includes:

[0082] The guide rail 30 and cylinder 31 are located at the top of the frame 1;

[0083] The mounting plate 32 is slidably mounted on the guide rail 30, and the output end of the cylinder 31 is connected to the side end of the mounting plate 32.

[0084] Cylinder 2 33 is mounted on mounting plate 32, and sliding bracket 2 is mounted on the output end of cylinder 2 33;

[0085] The guide shaft 34 is slidably mounted on the mounting plate 32 and is connected to the sliding frame 2. When the piston rod of cylinder 1 31 extends or retracts, it drives the mounting plate 32 to slide horizontally along the guide rail 30. When the piston rod of cylinder 2 33 extends, it drives the sliding frame 2 to move downward. When the piston rod retracts, it drives the sliding frame 2 to move upward. It can accurately complete the entire process of mold 3 alignment, sealing, forming and resetting, greatly improving production efficiency and operation accuracy.

[0086] In this embodiment, as Figure 9 As shown, the high-pressure container 4 is mounted on the inner side of the frame 1 via a fixed bracket 35. An ultrasonic probe 36 is installed inside the high-pressure container 4. The ultrasonic cavitation range of the ultrasonic probe 36 covers the mold 3. The ultrasonic probe 36 is electrically connected to an external ultrasonic generator via a wire. After the high-pressure container 4 is filled with liquid medium, the ultrasonic probe 36 is turned on. The micro-jet and shock wave generated by the ultrasonic cavitation effect act on the outer surface of the mold 3 and are transmitted to the internal powder through the flexible mold 3 wall, further promoting the uniformity and compaction of the powder.

[0087] In this embodiment, as Figure 6 As shown, a container 37 is slidably mounted on the support frame 6 via a track. The container 37 can be pushed and pulled onto the support frame 6 via a push-pull rod 38. After the split mold 3 is opened, the formed blank can be placed into the container 37, and the container 37 can be pulled out by the push-pull rod 38 to complete the material removal.

[0088] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the invention is limited to these examples; within the framework of the invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the invention as described above, which are not provided in detail for the sake of brevity.
