Description

Technical Field

[0001] The utility model belongs to the technical field of metal-based composite material processing equipment, and in particular relates to an ultrasonic processing device for metal-based composite materials. Background Art

[0002] Among the numerous composite materials, particle-reinforced metal matrix composites have been widely used in many important fields such as aerospace, military, automobile, and electronics industries due to their excellent comprehensive performance. Such materials are usually formed by evenly mixing metal powder with ceramic particles and then using hot isostatic pressing technology. However, this process faces a key challenge: due to the tiny size of the reinforcement phase particles, agglomeration is easy to occur, resulting in uneven mixing, which affects the performance of the final product.

[0003] In response to this challenge, the prior art (such as CN213854295U) proposes an ultrasonic treatment device for metal matrix composite materials. The device attempts to improve the sphericity and fluidity of the powder through ultrasonic treatment by setting a stirring shaft and stirring blades in a stirring tank and using an ultrasonic tank. Although the device improves the treatment effect of the powder to some extent, there are still deficiencies in its design, especially in terms of cleaning the inner wall of the stirring tank and the uniformity of material mixing.

[0004] This prior art fails to effectively solve the problem of local material accumulation during the mixing process because its stirring blade design is not sufficient to touch the inner wall of the mixing tank, thereby affecting the mixing efficiency and the effect of the subsequent processing process. In addition, this technology does not provide an effective mechanism to simplify equipment maintenance, especially in the replacement of consumables such as scrapers, which limits its efficiency and economy in industrial applications. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide an ultrasonic processing device for metal-based composite materials, which can achieve not only efficient and uniform stirring of the interior of a stirring tank through a uniquely designed stirring blade and scraper mechanism, but also, through an innovative stirring shaft design, the scraper can be separated from the inner wall of the stirring tank when there is no need to clean it, thereby reducing wear, and reduces the maintenance cost of the equipment through a simplified scraper replacement mechanism.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A metal matrix composite material ultrasonic processing device comprises a stirring tank and an ultrasonic tank, wherein a pump body for conveying materials is arranged between the stirring tank and the ultrasonic tank, a motor is arranged on the top of the stirring tank, a stirring shaft is connected to the output end of the motor, and a scraping mechanism is connected to the stirring shaft;

[0008] The scraper mechanism comprises a positioning frame, both sides of which are fixedly connected with a stopper, and the two stoppers are symmetrical about the center of the positioning frame; a pin connecting rod is inserted into the side of the stopper, and a scraper is rotatably connected to the side of the pin connecting rod.

[0009] Furthermore, the cross section of the stopper is arranged in a fan shape, and a plug-in slot is provided on the side of the stopper;

[0010] A splicing strip matched with the plug-in slot is fixedly connected to the side surface of the pin-jointed rod.

[0011] Furthermore, a pin-connecting plate is symmetrically fixedly connected to the other side of the pin-connecting rod, and a pin-connecting hole is formed through the side surface of the pin-connecting plate;

[0012] One end of the scraper is penetrated by a limiting hole corresponding to the pin connection hole.

[0013] Furthermore, a curved edge is provided at one side edge of the scraper.

[0014] Furthermore, stirring blades and stirring teeth are fixedly connected to the outer side of the stirring shaft, and the stirring blades and stirring teeth are staggered.

[0015] Furthermore, spoilers are evenly spaced on the inner opposite surfaces of the positioning frame along the height direction of the positioning frame, and the spoilers are symmetrical about the center of the positioning frame.

[0016] Furthermore, through holes are formed on the top and bottom of the positioning frame, and the stirring shaft passes through the through holes.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] The ultrasonic processing device for metal-based composite materials proposed in the utility model brings significant beneficial effects in the processing of metal-based composite materials through its unique technical solution. First, through the ingenious design between the stirring tank and the ultrasonic tank, combined with the pump body for conveying materials, the device can effectively achieve uniform mixing of metal powder and ceramic particles. This uniform mixing is the key to improving the performance of composite materials, especially in improving the strength, wear resistance and corrosion resistance of the materials. Compared with the prior art, the device can effectively avoid the agglomeration of materials during the mixing process, ensuring the high quality of the composite materials.

[0019] Secondly, the design of the scraping mechanism in the device, especially the close fit between the scraper and the inner wall of the mixing tank, can effectively clean the materials that may be attached to the inner wall of the mixing tank. This design not only improves the mixing efficiency, but also reduces the waste of materials, further ensuring the quality of the mixed materials and the uniformity of the mixing process. By improving the mixing efficiency and reducing the waste of materials, the device optimizes the production process and reduces the production cost.

[0020] Furthermore, the staggered layout of the stirring blades and stirring teeth designed on the stirring shaft, as well as the spoiler design in the positioning frame, jointly promote the uniformity of material flow during the stirring process. This design effectively solves the problem of easy agglomeration and stratification of materials in traditional stirring equipment, ensuring the performance stability and consistency of composite materials during the production process. By improving the fluidity and stirring uniformity of materials, this device significantly improves the final performance of composite materials and meets the high-standard industrial application requirements.

[0021] Finally, the design of the utility model simplifies the maintenance of the equipment and the replacement process of the scraper. Through the innovative pin-jointed rod and scraper connection method, the installation and replacement of the scraper becomes easier and faster. This design not only improves the operating efficiency of the equipment, but also reduces the long-term maintenance cost, bringing better user experience and economic benefits to users.

[0036] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0037] See also Figure 1-6 , a metal-based composite ultrasonic processing device, comprising a stirring tank 1 and an ultrasonic tank 5, and a pump body 6 for conveying materials is arranged between the stirring tank 1 and the ultrasonic tank 5. In the production process of metal-based composite materials, the stirring tank 1 undertakes the important task of mixing metal powder and ceramic particles evenly to ensure that the composite material has excellent physical and chemical properties; a motor 2 is arranged on the top of the stirring tank 1, and a stirring shaft 3 is connected to the output end of the motor 2, and a scraper mechanism 4 is connected to the stirring shaft 3. The rotation of the motor 2 drives the stirring shaft 3 to rotate synchronously, and the efficient mixing of the composite material powder is achieved by the rotation of the stirring shaft 3. The scraper mechanism 4 is designed to clean the materials that may be attached to the inner wall of the stirring tank 1 during the stirring process to ensure the stirring efficiency and mixing uniformity; the scraper mechanism 4 includes a positioning frame 41, and both sides of the positioning frame 41 are fixedly connected with a stopper 413, and the two stoppers 413 are symmetrical about the center of the positioning frame 41. The design of the stopper 413 not only provides a stable support for the pin-jointed rod 42, but also promotes the smooth movement of the scraper mechanism 4 and the effective cleaning of the material through its structural design; the side of the stopper 413 is plugged with the pin-jointed rod 42, and the side of the pin-jointed rod 42 is rotatably connected with the scraper 43. The scraper 43, as a component directly in contact with the inner wall of the mixing tank 1, plays a key role in reducing wear and improving cleaning efficiency.

[0038] See also Figure 3-5 The cross section of the stopper 413 is set to be fan-shaped, and a plug-in groove 4131 is provided on the side of the stopper 413. This design enables the pin-jointed rod 42 to achieve stable and flexible rotation in the stopper 413, thereby ensuring that the scraper 43 can effectively fit the inner wall of the mixing tank 1, thereby achieving effective cleaning of the inner wall of the mixing tank; the side of the pin-jointed rod 42 is fixedly connected with a splicing strip 422 that matches the plug-in groove 4131. The snap-fit ​​design between the splicing strip 422 and the plug-in groove 4131 not only facilitates the assembly and disassembly of the scraper mechanism 4, but also greatly simplifies the replacement process of the scraper 43, thereby improving the maintenance efficiency of the equipment.

[0039] See also Figure 5-6, the other side of the pin-joining rod 42 is symmetrically fixedly connected with a pin-joining plate 421, and a pin-joining hole 4211 is formed through the side of the pin-joining plate 421. This design allows the scraper 43 to be firmly connected to the pin-joining plate 421 through its limiting hole 431, further enhancing the structural stability and operational reliability of the scraping mechanism 4; a limiting hole 431 corresponding to the pin-joining hole 4211 is formed through one end of the scraper 43. Through the coordinated use of the limiting hole 431 and the pin-joining hole 4211, the scraper 43 can remain stable during the rotation of the stirring shaft 3, effectively avoiding swinging or falling off during the stirring process.

[0040] See also Figure 6 A curved edge 432 is provided at one side edge of the scraper 43. The design of the curved edge 432 takes into account the curvature of the inner wall of the mixing tank 1, ensuring that the scraper 43 can fit the inner wall of the mixing tank more closely, thereby improving the cleaning efficiency and reducing the material residue.

[0041] See also Figure 1-2 The outer side of the stirring shaft 3 is fixedly connected with a stirring blade 31 and a stirring tooth 32, and the stirring blade 31 and the stirring tooth 32 are arranged in a staggered manner. The staggered arrangement of the stirring blade 31 and the stirring tooth 32 is intended to improve the stirring efficiency and mixing uniformity, ensure that the metal powder and the ceramic particles can be fully and evenly mixed, avoid the occurrence of material agglomeration, and thus improve the overall performance of the composite material.

[0042] See also Figure 3 The inner opposite surfaces of the positioning frame 41 are evenly spaced with spoilers 412 along the height direction of the positioning frame 41, and the spoilers 412 are symmetrical about the center of the positioning frame 41. The provision of the spoilers 412 further optimizes the flow of materials during the mixing process, and promotes more uniform mixing and effective material mixing by changing the flow direction of the materials.

[0043] See also Figure 1-3 The top and bottom of the positioning frame 41 are penetrated with through holes 411, and the stirring shaft 3 passes through the through holes 411. The design of the through holes 411 allows the stirring shaft 3 to smoothly pass through the positioning frame 41, ensuring the close fit between the scraping mechanism 4 and the stirring shaft 3, thereby achieving efficient and uniform material stirring and effective inner wall cleaning.

[0044] The working principle of the utility model is:

[0045] The motor 2 drives the stirring shaft 3 to rotate synchronously. When the stirring shaft 3 rotates, the stirring blades 31 and stirring teeth 32 installed on the stirring shaft 3 stir and mix the raw materials in the stirring tank 1.

[0046] When the stirring shaft 3 rotates, the scraper mechanism 4 installed on the stirring shaft 3 will also rotate synchronously. When it is not necessary to clean the inner wall of the stirring tank 1, the stirring shaft 3 is rotated clockwise. When rotating clockwise, the scraper 43 connected to the pin connecting rod 42 will fit the side of the pin connecting rod 42 with the side of the positioning frame 41 under the action of centrifugal force, so that the scraper 43 can be separated from the inner wall of the stirring tank 1, thereby reducing the wear of the scraper 43;

[0047] When the stirring shaft 3 rotates counterclockwise, the scraper 43 will make the side of the scraper 43 contact with one side of the stopper 413 under the action of centrifugal force, and the edge of the scraper 43 will fit with the inner wall of the stirring tank 1, so as to clean the materials on the inner wall of the stirring tank 1.

[0048] When the scraper 43 needs to be replaced, it is only necessary to pull out the splicing strip 422 from the plug-in slot 4131. The mutual engagement between the splicing strip 422 and the plug-in slot 4131 can make the connection between the block seat 413 and the pin rod 42 more convenient, and it is also convenient for the scraper 43 to be replaced later.

[0049] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
