Description

Technical Field

[0001] The utility model relates to the technical field of powder metallurgy, in particular to a rocker-type powder feeding mechanism. Background Art

[0002] Powder metallurgy is a process technology for manufacturing metal powders or using metal powders as raw materials, through forming and sintering to manufacture metal materials, composite materials and various types of products. Powder metallurgy can manufacture materials with special properties such as high strength, high hardness, high wear resistance, and corrosion resistance by controlling the composition of the powder and the sintering process. Powder metallurgy can use waste metal materials as raw materials, reducing the dependence on natural resources.

[0003] In the existing related technologies, the following defects often exist: due to the limitations of the design of the module part, it is extremely easy to enter dust in the actual working environment. These dusts will continuously accumulate inside the module, causing continuous wear and damage to its precision components, resulting in the module being easily damaged, greatly affecting the normal operation and service life of the equipment. At the same time, during the process of the cylinder output force being transmitted to the powder box, due to reasons such as the non-optimized design of the transmission path, the force transmitted to the powder box is relatively small, affecting the normal working efficiency of the powder box. In addition, there is also a serious powder leakage problem at the powder box, which not only causes waste of powder materials but also pollutes the working environment.

[0004] Therefore, the utility model provides a rocker-type powder feeding mechanism. Content of the Utility Model

[0010] Preferably, a pressure regulating valve is rotatably installed on the surface of the motor housing.

[0011] Preferably, a knob switch is rotatably installed on the surface of the motor housing.

[0012] In summary:

[0013] In the present utility model, compared with the previous module and cylinder mechanism, the new mechanism has significant advantages. Firstly, in terms of reducing powder leakage from the powder cartridge, the new mechanism greatly reduces the possibility of powder leakage from the powder cartridge through a more reasonable structural design and a tighter fitting method.

[0017] Refer to Figure 1-2As shown in the figure, the present utility model provides a technical solution: a rocker - type powder feeding mechanism, which includes a first fixed plate 1 and a second fixed plate 2. The first fixed plate 1 and the second fixed plate 2 are fixedly connected. A motor housing 3 is fixedly connected to the side wall of the second fixed plate 2, and a motor body 4 is installed on the lower surface of the first fixed plate 1.

[0018] Next, specifically describe its overall specific settings and functions.

[0019] In this implementation scheme: A rocker 11 is rotatably installed on the surface of the second fixed plate 2. A first rotating shaft 9 is installed on the surface of the second fixed plate 2. A cylinder 12 is installed on the side wall of the first rotating shaft 9. The output end of the cylinder 12 is fixedly installed with a second rotating shaft 13. A connecting rod 14 is rotatably connected to the side wall of the second rotating shaft 13. A third rotating shaft 15 is fixedly connected to the side wall of the rocker 11. The third rotating shaft 15 and the connecting rod 14 are rotatably connected. A threaded shaft 16 is fixedly connected to the surface of the connecting rod 14. A connecting plate 17 is threadedly connected to the side wall of the threaded shaft 16. Two extension arms 18 are fixedly connected to the side wall of the connecting plate 17. Support shafts 8 are fixedly installed on one side of the two extension arms 18 close to each other. A powder box 20 is installed between the two extension arms 18.

[0020] Specifically, a blanking pipe 19 is communicated with the surface of the powder box 20. Two sensors 5 are installed inside the motor housing 3. A pressure gauge 10 is fixedly installed on the surface of the cylinder 12. A pressure regulating valve 6 is rotatably installed on the surface of the motor housing 3. A knob switch 7 is rotatably installed on the surface of the motor housing 3.

[0021] Working principle: The new rocker arm 11 type powder feeding mechanism has shown many advantages in the powder metallurgy industry. In this new mechanism, the powder box 20 is closely attached to a template, providing a stable basis for the powder feeding process. The motor body 4 serves as the power source, providing a reliable driving force for the material feeding. Under the action of the motor body 4, the extension arm 18 drives the rocker arm 11 to rotate, and this action then drives the connecting part to move back and forth. At the same time, the cylinder 12 outputs force through the connecting rod 14 and the fulcrum of the second rotating shaft 13, effectively transmitting the force to the powder box 20. This design enables the powder box 20 to be well attached to the template, ensuring the accuracy and stability of the powder feeding process. The setting of the feeding pipe 19 facilitates the feeding work of the powder inside the powder box 20, and the setting of the two sensors 5 facilitates the timely control work when the rocker arm 11 swings. By setting the pressure gauge 10, it is convenient to observe the air pressure change of the cylinder 12. The setting of the pressure regulating valve 6 facilitates the pressure regulating work of the equipment, and the knob switch 7 facilitates the opening and closing work of the equipment. Compared with the previous module and cylinder 12 mechanism, the new mechanism has significant advantages. First, in terms of reducing powder leakage from the powder box 20, through a more reasonable structural design and a tighter fitting method, the new mechanism greatly reduces the possibility of powder leakage from the powder box 20. This not only reduces the waste of powder but also avoids the adverse effects of the leaked powder on the surrounding environment and the operation of other mechanisms. Second, in terms of improving the stability of the mechanism, the cooperation between the various components of the new mechanism is more coordinated, and the movement process is more stable. The rotation of the rocker arm 11 and the back-and-forth movement of the connecting part cooperate with each other, plus the accurate transmission of the force output by the cylinder 12, making the entire powder feeding process more reliable. Finally, in terms of extending the service life of the machine platform, since the new mechanism reduces the impact of dust on key components, reduces the damage caused by powder leakage, and improves the stability of the mechanism at the same time, it can effectively extend the service life of the machine platform and reduce the maintenance cost of the equipment, providing a strong guarantee for the efficient production of the powder metallurgy industry.
