Description

Technical Field

[0001] This utility model relates to the field of powder metallurgy mixing technology, and more specifically to a mixing structure for powder metallurgy. Background Technology

[0002] Powder metallurgy is a process technology that manufactures metallic materials, composite materials, and various types of products by producing metal powders or using metal powders (or mixtures of metal and non-metal powders) as raw materials, followed by molding and sintering. Due to its advantages, powder metallurgy has become a key means of solving new material problems and plays a crucial role in the development of new materials. The mixing process involves uniformly mixing multiple metallurgical raw materials in a specific ratio to form a powder compact. This process is critical for subsequent pressing and molding, as its uniformity directly affects the performance and quality of the final product.

[0003] As shown in the prior art published in CN215877357U, although this prior art uses the output shaft of a drive motor to drive the driving gear and the driven gear to rotate, and the driven gear drives the stirring blades on the driven shaft to stir the metal powder, thereby achieving the effect of fully stirring the metal powder and improving the mixing degree of the metal powder, the positions of the stirring shaft and the stirring blades in this prior art are fixed, which means that the material between two adjacent stirring shafts cannot be fully contacted, thus affecting the mixing effect of this technical solution on powder metallurgy materials. Utility Model Content

[0004] To overcome the aforementioned deficiencies in the prior art, this utility model provides a mixing structure for powder metallurgy. A servo motor drives a movable disc and multiple stirring shafts to rotate. Because the gears on the stirring shafts mesh with the internal gear ring, the gears can rotate along the tooth path on the internal gear ring as the movable disc rotates. This, in turn, drives the spiral blades on the stirring shafts to agitate the materials. Thus, while the movable disc drives the stirring shafts to revolve, the stirring shafts can also rotate on their own axis, thereby improving the mixing effect on the materials and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a mixing structure for powder metallurgy, comprising a stirring component installed inside a tank for mixing materials; The stirring component includes a movable disc that is movably mounted on the top of the inner cavity of the tank via a rotating shaft. Multiple stirring shafts arranged in a ring array are movably mounted on the outside of the movable disc via bearings, and spiral blades are installed on the outside of the bottom end of the stirring shafts. Multiple stirring shafts extend to the top of the movable disc, and gears are installed at the top of the multiple stirring shafts. The same internal gear ring meshes with the external parts of the multiple gears. An installation ring for connecting to the inner wall of the tank is sleeved on the outside of the internal gear ring. The top of the tank is fitted with a fixed bracket, and the bottom of the fixed bracket is fitted with a fixing plate for connecting the tank on both sides. A servo motor is installed on the top of the fixed bracket, and the bottom end of the output shaft of the servo motor passes through the fixed bracket and the tank in sequence and is fixed together with the rotating shaft on the movable plate. The top of the tank is fitted with a support ring, and support plates for connecting and fixing brackets are installed on both sides of the support ring. The support ring is equipped with multiple sets of auxiliary components for knocking off materials. Each set of auxiliary components includes multiple mounting holes, which are opened on the outside of the support ring. Each mounting hole is threaded with a mounting post. A spring and a striking ball are installed on the end of the mounting post near the tank body. The striking ball is located on the side of the spring near the tank body and is in contact with the tank body.

[0006] In a preferred embodiment, the top of the tank is provided with a linkage plate, which is sleeved outside the output shaft of the servo motor. A lever for actuating the spring and striking the ball is installed at the bottom of the end of the linkage plate away from the output shaft of the servo motor.

[0007] In a preferred embodiment, a feed inlet is provided on the front side of the top of the tank, and the feed inlet is located at the bottom of the movable plate; A horizontal plate is installed on one side of the bottom of the tank, and a sealing plate for sealing the tank is provided at the bottom of the horizontal plate. The top of the sealing plate near the horizontal plate is movably connected to the bottom of the horizontal plate through a rotating shaft. A drive motor is installed on the top of the horizontal plate, and the output shaft of the drive motor passes through the horizontal plate and is fixed together with the rotating shaft on the sealing plate. A positioning shell is installed on the side of the tank bottom away from the horizontal plate, and the bottom end of the positioning shell is sleeved outside the bottom end of the sealing plate.

[0008] In a preferred embodiment, scrapers are installed at the bottom of both ends of the movable disc, and the scrapers are in contact with the inner wall of the tank.

[0009] The technical effects and advantages of this utility model are as follows: The servo motor drives the movable disc and multiple stirring shafts to rotate. Because the gears on the stirring shafts mesh with the internal gear ring, the gears can rotate along the tooth path on the internal gear ring as the movable disc rotates. This drives the spiral blades on the stirring shafts to agitate the materials. In this way, the stirring shafts can rotate on their own axis while the movable disc drives the stirring shafts to revolve, thereby improving the stirring effect on the materials. By connecting the linkage plate to the output shaft of the servo motor, the linkage plate can drive the lever to rotate together with the output shaft of the servo motor, and reciprocate to move the spring-supported striking ball. When the striking ball separates from the lever, the striking ball can strike the tank body by the rebound force of the spring. The vibration generated by the strike can shake off the material adhering to the inner wall of the tank, thereby improving the cleaning efficiency of the scraper and reducing the adhesion of material.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Refer to the instruction manual appendix Figure 1-5 This utility model provides a mixing structure for powder metallurgy, including a stirring component installed inside the tank 1 for mixing materials; The stirring component includes a movable disc 2 movably mounted on the top of the inner cavity of the tank 1 via a rotating shaft. Multiple stirring shafts 3 arranged in a circular array are movably mounted on the outside of the movable disc 2 via bearings, and spiral blades 4 are mounted on the bottom of the stirring shafts 3. The top ends of the multiple stirring shafts 3 extend to the top of the movable disc 2, and gears 5 are mounted on the top ends of the multiple stirring shafts 3. The gears 5 are externally meshed with the same internal gear ring 6. An installation ring 7 for connecting to the inner wall of the tank 1 is sleeved on the outside of the internal gear ring 6. A fixed bracket 8 is sleeved on the top of the tank 1, and fixed plates 9 for connecting the tank 1 are mounted on both sides of the bottom end of the fixed bracket 8. A servo motor 10 is mounted on the top of the fixed bracket 8, and the bottom end of the output shaft of the servo motor 10 passes through the fixed bracket 8 and the tank 1 in sequence and is fixed together with the rotating shaft on the movable disc 2.

[0014] When stirring powder metallurgy materials, the servo motor 10 drives the movable disk 2 to rotate, which in turn drives multiple stirring shafts 3 to rotate. Because the gear 5 on the stirring shaft 3 meshes with the internal gear ring 6, the gear 5 can rotate along the tooth path on the internal gear ring 6 as it rotates with the movable disk 2, thereby driving the spiral blades 4 on the stirring shaft 3 to stir the material. This allows the stirring shaft 3 to rotate on its own axis while the movable disk 2 drives the stirring shaft 3 to revolve, thus improving the stirring effect on the material. At the same time, the servo motor 10 and the tank 1 are supported and fixed by the fixed bracket 8 and the fixed plate 9 to ensure the stability of the servo motor 10 and the tank 1. Since scrapers 24 are installed at both ends of the movable disk 2 and the scrapers 24 are in contact with the inner wall of the tank 1, the movable disk 2 can drive the scrapers 24 to rotate together, and the scrapers 24 scrape and clean the inner wall of the tank 1 to prevent debris from adhering.

[0015] To improve the cleaning effect of the scraper 24, it is necessary to reduce the adhesion between debris and the tank 1, such as... Figure 1 , 2 As shown in Figure 4, a support ring 11 is sleeved on the top of the tank body 1, and support plates 12 for connecting and fixing brackets 8 are installed on both sides of the support ring 11. Multiple sets of auxiliary components for knocking off materials are provided on the outside of the support ring 11. Each set of auxiliary components includes multiple mounting holes 13. The mounting holes 13 are opened on the outside of the support ring 11. Each mounting hole 13 is threaded with a mounting post 14. A spring 15 and a striking ball 16 are installed on the end of the mounting post 14 near the tank body 1. The striking ball 16 is located on the side of the spring 15 near the tank body 1 and contacts the tank body 1. A linkage plate 17 is provided on the top of the tank body 1. The linkage plate 17 is sleeved on the outside of the output shaft of the servo motor 10. A lever 18 for actuating the spring 15 and the striking ball 16 is installed at the bottom of the end of the linkage plate 17 away from the output shaft of the servo motor 10.

[0016] When handling debris adhering to the inner wall of tank 1, the linkage plate 17 is fixed to the output shaft of the servo motor 10, allowing the linkage plate 17 to drive the lever 18 to rotate along with the output shaft of the servo motor 10. During rotation, the lever 18 can reciprocate to move the striking ball 16 supported by the spring 15. When the striking ball 16 separates from the lever 18, the striking ball 16 strikes the tank 1 with the rebound force of the spring 15. The vibration generated by the strike can dislodge the material adhering to the inner wall of tank 1, allowing the dislodged material to participate in the mixing process again, thereby improving the mixing effect. Since the mounting column 14 is threadedly connected to the support hole, the operator can rotate and disassemble the mounting column 14 to remove the spring 15 and the striking ball 16 for inspection, maintenance, or replacement, thereby improving the convenience of disassembly and assembly of auxiliary parts.

[0017] When using the above structure, it is necessary to transport metallurgical materials into the tank 1, such as... Figure 1 , 2 As shown in Figure 5, a feed inlet 19 is provided on the front side of the top of the tank body 1, and the feed inlet 19 is located at the bottom of the movable plate 2; a horizontal plate 20 is installed on one side of the bottom of the tank body 1, and a sealing plate 21 for sealing the tank body 1 is provided at the bottom of the horizontal plate 20. The top of the sealing plate 21 near the horizontal plate 20 is movably connected to the bottom of the horizontal plate 20 through a rotating shaft. A drive motor 22 is installed on the top of the horizontal plate 20, and the output shaft of the drive motor 22 passes through the horizontal plate 20 and is fixed together with the rotating shaft on the sealing plate 21; a positioning shell 23 is installed on the side of the bottom of the tank body 1 away from the horizontal plate 20, and the bottom of the positioning shell 23 is sleeved outside the bottom of the sealing plate 21.

[0018] When conveying materials, the staff conveys the materials into the tank 1 through the feed inlet 19, so that the stirring shaft 3 can stir and mix the materials. After the materials are mixed, the staff operates the drive motor 22 to drive the sealing plate 21 to rotate, so that the sealing plate 21 is misaligned with the tank 1, thereby facilitating the discharge of materials from the tank 1. The positioning shell 23 supports and limits the sealing plate 21 when sealing the tank 1, thereby ensuring the stability and support strength of the positioning shell 23.

[0019] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
