Description

Technical Field

[0001] This utility model relates to the field of powder metallurgy technology, specifically to a vibrating feeding mechanism for powder metallurgy. Background Technology

[0002] In the production process of powder metallurgy, the discharge of metal powder is a key process connecting raw material storage and forming processing. Its discharge stability, sealing performance and metal powder quality assurance directly affect the precision and performance of the subsequent formed parts.

[0003] Currently, most powder metallurgy discharge devices on the market adopt simple pipeline discharge structures, relying solely on gravity to allow metal powder to fall naturally. Such devices have obvious drawbacks: on the one hand, metal powder is prone to agglomeration and blockage in the discharge channel, leading to discharge interruptions and requiring frequent manual cleaning, which seriously affects production efficiency; on the other hand, the connection between the discharge channel and the external receiving and discharge devices lacks reliable sealing and fixing structures, which not only easily leads to metal powder leakage, causing raw material waste and working environment pollution, but may also cause displacement of the device during operation due to loose connections, further aggravating the problem of unstable discharge. Therefore, we propose a vibratory discharge mechanism that can effectively improve the continuity, stability and product quality of powder discharge. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Please see Figure 1-5 This utility model provides a technical solution: a vibrating feeding mechanism for powder metallurgy, comprising:

[0027] The support assembly includes a support leg 1 and a support plate 2. The support leg 1 is installed on the ground, and the support plate 2 is installed on top of the support leg 1. Before the mechanism is in operation, the support leg 1 is first securely installed on the ground at a designated position through the bottom structure, and then the support plate 2 is precisely assembled onto the top of the support leg 1. When the various components of the mechanism are in operation, the support leg 1 provides vertical support for the entire mechanism, while the support plate 2 bears the weight of core components such as the discharge port 3 and the vibrating motor 4. This achieves the function of providing a stable installation foundation and load-bearing support for the entire mechanism, thereby greatly improving the structural stability of the mechanism during operation.

[0028] The discharge port 3 is installed through the center of the support plate 2 and is used to seal and discharge metal powder. During the discharge operation, the external discharge device transports the metal powder into the discharge port 3. The metal powder flows downward along the inner wall of the discharge port 3. During the process, the discharge port 3 relies on its own structure and sealing components to achieve a sealed connection with the external device, thereby guiding the metal powder to flow in a directional manner and preventing powder leakage, thus greatly improving the sealing performance and accuracy of the metal powder discharge.

[0029] Vibration motor 4 is installed on one side of the bottom of support plate 2 to vibrate discharge port 3. When metal powder flows in discharge port 3, vibration motor 4 is started. The vibration force generated by vibration motor 4 is transmitted to discharge port 3 through support plate 2, so that discharge port 3 produces continuous and uniform vibration. The vibration can break the agglomeration of metal powder and prevent powder from accumulating and blocking in discharge port 3. This achieves the function of assisting the smooth flow of metal powder and preventing the discharge channel from being blocked, thereby greatly improving the smoothness and efficiency of discharge.

[0030] The clamping component 5 is located on the upper and lower sides of the discharge port 3 and is used to clamp and fix the discharge port 3 to the external receiving device and discharge device. When connecting to the external device, the clamping component 5 is respectively positioned at the interface between the upper and lower sides of the discharge port 3 and the external receiving device and discharge device. The clamping component 5 clamps and fixes the interface through its structural operation, preventing the external device from shifting or separating from the discharge port 3 during the operation of the mechanism. This achieves the function of firmly connecting the discharge port 3 to the external device, thereby greatly improving the reliability of the connection between the mechanism and the external equipment.

[0031] Furthermore, the clamping assembly 5 includes a first retaining ring 501 and a second retaining ring 502 installed on the sides of the discharge port 3. A first fixing block 503 and a second fixing block 504 are respectively fixedly connected to both sides of the first retaining ring 501 and the second retaining ring 502. A fastening bolt 505 is threadedly connected to the inside of the first fixing block 503. The other end of the fastening bolt 505 extends to the other side of the second fixing block 504 and is threadedly connected to a round-head nut 506. An anti-loosening mechanism 8 is provided on the side of the second fixing block 504 away from the first fixing block 503. When the clamping assembly 5 is working, the first retaining ring 501 and the second retaining ring 502 are first wrapped around the discharge port 3. The interface between the feed port 3 and the external device is aligned so that the first fixing block 503 and the second fixing block 504 are aligned accordingly. Then, the fastening bolt 505 is screwed in from one side of the first fixing block 503, passes through the second fixing block 504, and then the round head nut 506 is put on and tightened. Finally, the round head nut 506 is reinforced by the anti-loosening mechanism 8. Throughout the process, the first retaining ring 501 and the second retaining ring 502 wrap around the interface from the periphery. The fastening bolt 505 and the round head nut 506 provide axial clamping force, and the anti-loosening mechanism 8 prevents the connection from loosening. This achieves the effect of multi-directionally stabilizing the interface, thereby greatly improving the fixing effect and durability of the clamping component 5.

[0032] Furthermore, the anti-loosening mechanism 8 includes an adjusting plate 801 installed on the side of the second fixing block 504. An adjusting groove 802 is provided on one side of the adjusting plate 801. A positive and negative lead screw 803 is rotatably connected to one side of the inner wall of the adjusting groove 802. The other side of the positive and negative lead screw 803 extends to the outside of the adjusting plate 801 and is fixedly connected to a turntable 804. Lead screw nuts 805 are threaded to the threaded portions at both ends of the positive and negative lead screw 803. One side of the lead screw nut 805 extends through the adjusting groove 802 to the outside of the adjusting plate 801 and is fixedly connected to a clamping block 806. When it is necessary to adjust the round-head nut 506... When performing anti-loosening reinforcement, the turntable 804 is rotated, which drives the positive and negative lead screws 803 to rotate in the adjustment groove 802. Since the threads at both ends of the positive and negative lead screws 803 are in opposite directions, the lead screw nuts 805 will move towards each other along the adjustment groove 802, thereby pushing the clamping block 806 to approach and clamp the round head nut 506. Through the limiting effect of the clamping block 806 on the round head nut 506, the round head nut 506 is prevented from rotating and loosening when the mechanism vibrates, thereby achieving the function of anti-loosening fixation of the round head nut 506, which greatly improves the stability and anti-loosening effect of the clamping assembly 5 connection.

[0033] Furthermore, the side of the clamping block 806 away from the lead screw nut 805 adopts an arc-shaped design, and the curvature of its arc surface matches the outer arc of the round head nut 506. During the clamping process of the clamping block 806 clamping the round head nut 506, the arc-shaped clamping surface can completely fit with the outer arc surface of the round head nut 506, increasing the contact area between the two and making the clamping force more evenly applied to the round head nut 506. This avoids excessive local force that could damage the component, while also more firmly restricting the rotation of the round head nut 506. This achieves a tighter and more even clamping of the round head nut 506, thereby greatly improving the clamping reliability of the anti-loosening mechanism 8 and the service life of the component.

[0034] Furthermore, the inner walls of the first retaining ring 501 and the second retaining ring 502 are provided with sealing gaskets 507 for sealing, and the other end of the sealing gasket 507 is in close contact with the outer wall of the discharge port 3. When the first retaining ring 501 and the second retaining ring 502 clamp the discharge port 3 with the interface of the external device, the sealing gasket 507, under the clamping force of the retaining ring, tightly fits the gap between the outer wall of the discharge port 3 and the inner wall of the retaining ring, preventing metal powder from leaking from the gap. At the same time, it can also prevent external dust and other impurities from entering the discharge channel and contaminating the metal powder, thereby achieving the function of sealing the interface gap, preventing powder leakage and contamination, and thus greatly improving the sealing of the discharge process and the purity of the metal powder.

[0035] Furthermore, an air inlet 6 and an air outlet 7 are fixedly connected to one side of the discharge port 3 from bottom to top. Before the discharge operation, inert gas is introduced into the discharge port 3 through the air inlet 6. The inert gas gradually fills the discharge port 3, squeezing out the air inside through the air outlet 7, thus creating an inert gas environment inside the discharge port 3. This prevents the metal powder from oxidizing when it comes into contact with air. At the same time, during the discharge process, inert gas can be continuously replenished through the air inlet 6 as needed to maintain the inert environment inside the discharge port 3. This achieves the effect of creating an inert environment and preventing the metal powder from oxidizing, thereby greatly improving the quality of the metal powder and the stability of subsequent processing.

[0036] Furthermore, a mounting base plate is fixedly connected to the bottom of support leg 1, and multiple sets of reinforcing plates are installed between the mounting base plate and the support leg to enhance the connection strength. During installation, the mounting base plate at the bottom of support leg 1 is fixed to the ground with bolts and other connectors. The mounting base plate increases the contact area between support leg 1 and the ground, making the support leg 1 more stable. At the same time, the reinforcing plates connect the mounting base plate and support leg 1, dispersing the pressure transmitted from support leg 1 to the mounting base plate, reducing stress concentration at the connection point, and preventing loosening or damage after long-term use. This enhances the connection strength between support leg 1 and the mounting base plate, improves the overall installation stability of the mechanism, and thus greatly improves the load-bearing capacity and service life of the mechanism.

[0037] Furthermore, an anti-slip sleeve is fixedly connected to the outer surface of the turntable 804, and the outer surface of the anti-slip sleeve has anti-slip texture. When the operator rotates the turntable 804 to adjust the anti-loosening mechanism 8, the anti-slip sleeve and anti-slip texture increase the friction between the hand and the turntable 804, preventing the hand from slipping during rotation. This allows the operator to control the rotation angle and force of the turntable 804 more easily and accurately, thus facilitating the operator to rotate the turntable 804 and preventing hand slippage, thereby greatly improving the convenience and accuracy of operation.

[0038] Working Principle: To meet the production requirements of high-precision metal structural parts, a vibrating discharge mechanism is needed in the raw material conveying section of the powder metallurgy forming production line to quantitatively, sealedly, and without clogging the metal powder. During operation, the operator first fixes the entire device to the designated position using the mounting plate at the bottom of the support leg 1. Multiple sets of reinforcing plates between the mounting plate and the support leg 1 significantly enhance the connection strength, preventing displacement due to vibration during operation and ensuring overall operational stability. Then, the operator connects the external discharge device to the top of the discharge port 3 and the external receiving device to the bottom of the discharge port 3. Finally, the first retaining ring 5 is used... 01 and the second retaining ring 502 are wrapped around the interface. At this time, the sealing gasket 507 on the inner wall of the first retaining ring 501 and the second retaining ring 502 is tightly against the outer wall of the discharge port 3, which can effectively prevent metal powder from leaking from the interface gap during the conveying process, reduce material waste and avoid polluting the working environment. Then, the worker passes the fastening bolt 505 through the first fixing block 503 and screws it into the second fixing block 504 until the end of the fastening bolt 505 extends to the other side of the second fixing block 504. Then, the round head nut 506 is put on and tightened to achieve initial fixation. After that, the turntable 804 is rotated, so that the turntable 804 drives the positive and negative screw 803 in the adjusting groove 802 to rotate. When the positive and negative lead screws 803 rotate, the lead screw nuts 805 at both ends of the screw thread will move towards each other under the limiting action of the adjusting groove 802, thereby pushing the clamping block 806 closer to the round head nut 506. Since the arc-shaped surface of the clamping block 806 matches the outer arc of the round head nut 506, the clamping block 806 can finally fit tightly against both sides of the round head nut 506, effectively preventing the round head nut 506 from loosening during the vibration of the mechanism, further improving the reliability of the clamping assembly 5, and ensuring that the external device and the discharge port 3 always maintain a stable connection. After completing the preliminary preparation work, the operator then uses the air inlet on one side of the discharge port 3. 6. Inert gas is introduced into the discharge port 3. The inert gas can replace the air in the discharge port 3, preventing the metal powder from reacting with oxygen in the air and affecting the powder quality. Then the air is discharged through the air outlet 7, creating an inert environment inside the discharge port 3 and ensuring the chemical stability of the metal powder. Next, the vibration motor 4 on one side of the bottom of the support plate 2 is started. The vibration force generated by the vibration motor 4 is transmitted to the support plate 2, and then transmitted from the support plate 2 to the discharge port 3, so that the discharge port 3 produces continuous and stable vibration. This vibration can effectively break the agglomeration of metal powder in the discharge port 3, prevent the powder from blocking the discharge channel, and ensure a smooth and efficient discharge process.At this time, the external discharge device conveys the metal powder into the discharge port 3. Under the action of vibration, the metal powder flows smoothly downward along the inner wall of the discharge port 3 and finally falls accurately into the receiving device below. Throughout the discharge process, the combination of a sealed discharge environment and stable vibration ensures the conveying accuracy of the metal powder and avoids problems such as powder moisture, contamination, or blockage. At the same time, the design of the air inlet 6 and the air outlet 7 can adjust the air pressure in the discharge port 3 according to actual needs, further optimizing the powder flow state, improving discharge efficiency, and providing a strong guarantee for the smooth progress of subsequent powder metallurgy forming processes.
