Abstract

This invention relates to the field of powder metallurgy technology and discloses a powder metallurgy processing equipment and method, including a metal powder die-casting mechanism and a rotary vibration compaction mechanism. The structure includes an upper driven plate capable of driving the longitudinal movement of an internal guide plate, a lower driving plate located directly below the upper driven plate and capable of movement, a hemisphere that forces the upper driven plate to produce intermittent vibration when the lower driving plate rotates, and a drive motor capable of driving the lower driving plate to rotate. This powder metallurgy processing equipment and method, through the motor driving the hemisphere and hemispherical groove on the end face to rotate and cooperating with spring reset, causes the guide plate inside the mold to generate high-frequency pure axial vibration. This aims to solve the problems of low compaction efficiency and high overall vibration loss in existing equipment. Furthermore, the vibration can be concentrated on the internal guide plate, and the vibration moves along the axial direction of the core component, thereby generating a more concentrated vibration effect with a smaller vibration source and reducing the negative impact of vibration on the core component, thus improving the practicality of the equipment.

Description

Technical Field

[0001] This invention relates to the field of powder metallurgy technology, specifically to a powder metallurgy processing equipment and its processing method. Background Technology

[0002] Metal powder metallurgy is a process technology that uses forming and sintering processes to turn metal powders into materials and products. It is a very common process technology in the modern metal processing field and is often used to produce alloy products.

[0003] For example, Chinese patent publication number "CN119609128B" discloses "a powder metallurgy processing equipment and its processing method," whose main structure includes a feeding assembly, a powder compression mold frame, lifting molds and a support tray, a pushing mold and sweeping assembly, a powder evenly spreading assembly, a vibration feeding assembly, and a sintering furnace. The feeding assembly is mounted on the powder compression mold frame, and the two lifting molds and the support tray are slidably connected to the powder compression mold frame. The pushing mold and sweeping assembly is mounted on the powder compression mold frame and is slidably connected to the two lifting molds and the support tray. The vibration feeding assembly... The feeding assembly abuts against the powder compression mold frame, and both powder spreading assemblies are set on the powder compression mold frame. The sintering furnace is set on the powder compression mold frame. The powder spreading assembly can push the lifting mold and the support tray into the sintering furnace. The sintering furnace supports the lifting mold and the support tray. This powder metallurgy processing equipment can perform vibration feeding during the powder feeding process and adopts multiple saturated metal powder feeding. Under the premise of ensuring sufficient metal powder feeding, more gas in the powder can be released, making the powder more compact and producing a structure with higher strength during pressing.

[0004] However, in actual processing, the aforementioned powder metallurgy processing equipment requires vibration during the feeding process of the lifting mold. Furthermore, the vibration component is located on one side of the lifting mold (the two are indirectly connected through multiple components). This causes the vibration component to drive multiple other mechanisms to vibrate when driving the lifting mold to vibrate. This vibration reduces the service life of the equipment's connecting parts. Moreover, the vibration does not occur along the axial direction of the connecting parts, and its deflection will exacerbate the damage to the equipment. Therefore, it increases the power consumption and has poor vibration efficiency transmission capability, resulting in poor vibration effect. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a powder metallurgy processing equipment and method. Utilizing the misalignment and overlap between the hemisphere and the hemispherical groove during rotation, a longitudinal vibration effect is achieved on the built-in guide plate, resulting in a more compact metal powder within the compaction chamber. Furthermore, this vibration is concentrated within the built-in guide plate and moves axially along the core component, thereby generating a more concentrated vibration effect with a smaller vibration source and reducing the negative impact of vibration on the core component. This improves the practicality of the equipment and solves the aforementioned technical problems.

[0006] To achieve the above objectives, the present invention provides a powder metallurgy processing equipment, including a metal powder die casting mechanism.

[0009] Preferably, the compaction head and the compaction cavity are adapted to each other, and the two form the desired die-cast product after stamping.

[0010] Preferably, the top of the hollow rotating shaft is provided with a concave structure for fixing the rod body fixing groove at the bottom end of the guide rod. The interior of the hollow rotating shaft is provided with a longitudinal component movable cavity. The bottom end of the hollow rotating shaft is provided with a second rod body through hole communicating with the bottom end of the longitudinal component movable cavity. The hollow rotating shaft is provided with an upper driven plate at the top of the longitudinal component movable cavity. The drive motor is fixedly installed inside a motor mounting base. The shaft of the longitudinal drive shaft passes through the second rod body through hole and extends into the interior of the longitudinal component movable cavity. The bottom surface edge of the upper driven plate is provided with multiple hemispherical shapes arranged in a ring array and protruding downwards. The longitudinal drive shaft is fitted with a first helical spring in a compressed state around the rod body located between the bottom end of the longitudinal component movable cavity and the bottom end of the lower drive plate. The upper surface of the lower drive plate is provided with multiple hemispherical grooves arranged in a ring array and protruding downwards, and the hemispherical grooves and the hemispherical shapes are corresponding vertically.

[0011] Preferably, the structural shape of the cross-section of the second rod through the hole is consistent with the structural shape of the cross-section of the longitudinal drive shaft, both being circular structures, and the structural dimensions of the cross-section of the second rod through the hole match the structural dimensions of the cross-section of the longitudinal drive shaft.

[0012] Preferably, it also includes a telescopic finished product export mechanism, the structure of which includes a longitudinal hollow column fixedly installed at the bottom of the central workbench and having a hollow internal structure, a piston plate that can move longitudinally after liquid is injected, a second helical spring placed inside the piston plate and having a downward elastic damping effect on the piston plate, and a bottom fixing plate that moves with the piston plate and can drive the motor fixing seat to move.

[0013] Preferably, the telescopic finished product export mechanism further includes a top fixing plate integrally disposed on the top of the longitudinal hollow column and fixedly installed on the bottom of the central workbench. The interior of the longitudinal hollow column is provided with a liquid compression chamber, and the bottom of the liquid compression chamber is provided with a liquid reservation chamber. The bottom end of the liquid reservation chamber is provided with a No. 3 rod through hole communicating with the external space. The outer circumferential surface of the longitudinal hollow column is provided with a liquid docking channel communicating with one side of the liquid reservation chamber. The interior of the liquid compression chamber is provided with a piston plate that can move along its axial direction. The top of the piston plate is provided with a No. 2 helical spring in a compressed state. The bottom end of the piston plate is fixedly installed with a longitudinal telescopic rod passing through the No. 3 rod through hole. The bottom end of the longitudinal telescopic rod is fixedly installed with a bottom fixing plate. The bottom of the motor fixing seat is fixedly installed on the corresponding upper surface of the bottom fixing plate.

[0014] Preferably, the structural shape of the perforated cross section of the third rod is consistent with the structural shape of the cross section of the longitudinal telescopic rod, both being polygonal structures, and the structural dimensions of the perforated cross section of the third rod match the structural dimensions of the cross section of the longitudinal telescopic rod.

[0015] The present invention also provides a processing method for powder metallurgy processing equipment, comprising: S1: Connect the liquid docking channel to the liquid circuit of a hydraulic device that can control the direction of liquid flow and liquid pressure, and then fix the support base plate in a horizontal position in the working position. S2: Move the built-in guide plate to the lowest stroke position of the compaction chamber, and then introduce the metal powder into the compaction chamber; S3: Start the drive motor. Its rotor will drive the longitudinal drive shaft to rotate. Similarly, the longitudinal drive shaft will drive the lower drive disk to rotate. Due to the special structure of the guide rod, the hollow shaft and the upper driven disk will remain stationary. The rotating lower drive disk will cause the hemispherical groove and the hemisphere to intermittently meet, overlap, and separate. When they separate, the protruding end of the hemisphere abuts against the upper surface of the lower drive disk, forcing the hollow shaft to overcome the elastic force of the first helical spring and move upward. When they meet and overlap, the hemisphere is embedded in the hemispherical groove. Under the action of the return elastic force of the first helical spring and its own gravity, the hollow shaft moves downward rapidly. During the intermittent upward and downward movement, the built-in guide plate will generate longitudinal vibration. This vibration can make the metal powder inside the compaction chamber more compact. After the hemispherical groove and the hemisphere meet for the last time, the drive motor can be turned off, and then the metal powder can be filled into the compaction chamber. S4: After the metal powder filling is completed, the hydraulic telescopic cylinder is activated, and the compaction head will move downward. When the compaction head contacts the metal powder inside the compaction chamber, it will exert pressure on the metal powder until the metal powder is die-cast into the desired finished product, thus completing the die-casting process of the metal powder. After the die-casting is completed, the compaction head is controlled to return to its original position by the hydraulic telescopic cylinder. S5: Start the hydraulic equipment to allow liquid to enter the liquid compression chamber. Under the liquid pressure, the piston plate will drive the bottom fixed plate to move upward. The bottom fixed plate will indirectly drive the outlet rod and the built-in guide plate to move upward. Finally, the built-in guide plate will drive the die-cast product upward until the product is completely discharged.

[0016] Compared with the prior art, the present invention provides a mine wastewater treatment device, which has the following beneficial effects: 1. By utilizing the misalignment and overlap between the hemisphere and the hemispherical groove during rotation, a longitudinal vibration effect is achieved on the built-in guide plate, thereby making the metal powder more compact in the compaction chamber. Furthermore, the vibration can be concentrated on the built-in guide plate. In addition, the vibration moves along the axial direction of the core component, thereby producing a more concentrated vibration effect with a smaller vibration source and reducing the negative impact of vibration on the core component, thus improving the practicality of the equipment.

[0017] 2. Equipped with a metal powder die-casting mechanism, the central worktable serves as the main load-bearing structure, forming a stable support with the bottom support rod and support base plate. The hydraulic telescopic cylinder and compaction head are fixed by the top support rod, resulting in a stable structure and balanced force distribution. The powder die-casting mold is embedded in the worktable and has a compaction cavity. With the polygonal / circular matching first rod through the hole and the guide rod, it ensures that the built-in guide plate only moves axially to prevent deflection, while accurately bearing and stamping, realizing the integration of powder holding, compaction, and guidance. With the guide rod, the finished product can be demolded efficiently. The overall structure is compact, the positioning is accurate, the movement is stable, the stamping accuracy is high, and the operation is reliable.

[0018] 3. Equipped with a rotary vibration compaction mechanism, the lower drive disk is rotated by a drive motor. The intermittent engagement of the bottom hemisphere of the upper driven disk and the hemispherical groove of the lower drive disk, combined with the compressed No. 1 helical spring, causes the hollow rotating shaft and the built-in guide plate to generate pure longitudinal axial vibration. The vibration is directly concentrated on the core working component without vibrating the entire machine. It achieves efficient powder compaction with a low-power vibration source, making the metal powder denser, while avoiding vibration deviation that could damage the connecting parts. At the same time, the limiting structure of the guide rod and the perforation can prevent the driven component from deflecting. The structure is compact, has high vibration efficiency, low equipment wear, and is highly practical. Attached Figure Description

After the metal powder is filled, the hydraulic telescopic cylinder 16 is activated, and the compaction head 17 moves downward. When the compaction head 17 contacts the metal powder inside the compaction cavity 110, it will exert pressure on the metal powder until the metal powder is die-cast into the desired finished product, thus completing the die-casting of the metal powder. After the die-casting is completed, the hydraulic telescopic cylinder 16 controls the compaction head 17 to return to its original position, thereby realizing the die-casting of the metal powder.

Its structure includes an upper driven plate 27 that can drive the built-in guide plate 112 to move longitudinally, a lower drive plate 29 located directly below the upper driven plate 27 and capable of movement, a hemisphere 210 that can force the upper driven plate 27 to produce intermittent vibration when the lower drive plate 29 rotates, and a drive motor 22 that can drive the lower drive plate 29 to rotate. When the drive motor 22 is started, its rotor will drive the longitudinal drive shaft 211 to rotate. Similarly, the longitudinal drive shaft 211 will drive the lower drive plate 29 to rotate. Due to the special structural shape of the guide rod 113, the hollow rotating shaft 24 and the upper driven plate 27 will remain stationary, while the rotating lower drive plate (29) will cause the hemisphere groove (28) and the hemisphere (210) to intermittently meet, overlap and separate. When the two separate and misalign, the protruding end of the hemisphere (210) abuts against the upper surface of the lower drive disk (29), forcing the hollow shaft (24) to overcome the elastic force of the first helical spring (213) and move upward. When the two meet and overlap, the hemisphere (210) is embedded in the hemisphere groove (28). Under the action of the reset elastic force of the first helical spring (213) and its own gravity, the hollow shaft (24) moves downward rapidly. During the intermittent upward and downward movement, the built-in guide plate 112 will generate longitudinal vibration. This vibration can make the metal powder inside the compaction cavity 110 more compact. After the last overlap of the hemisphere groove 28 and the hemisphere 210 is completed, the drive motor 22 can be turned off, and then the metal powder is filled into the compaction cavity 110.

The bottom surface edge of the upper driven disk 27 is provided with a plurality of annular arrays of downwardly protruding hemispheres 210. The upper surface of the lower drive disk 29 is provided with a plurality of annular arrays of downwardly recessed hemispherical grooves 28.

When the hydraulic equipment is started, liquid enters the liquid compression chamber 33. Under liquid pressure, the piston plate 37 will drive the bottom fixing plate 310 to move upward. The bottom fixing plate 310 will indirectly drive the export rod 113 and the built-in guide plate 112 to move upward. Finally, the built-in guide plate 112 will drive the die-cast finished product to move upward until the finished product is completely exported.

[0028] For details regarding the specific structure of the telescopic finished product export mechanism 3, please refer to [link / reference]. Figure 7 and Figure 8It also includes a top fixing plate 32 integrally disposed on the top of the longitudinal hollow column 31 and fixedly installed on the bottom of the central workbench 11. The longitudinal hollow column 31 has a liquid compression chamber 33 inside, and a liquid reserve chamber 34 is disposed at the bottom of the liquid compression chamber 33. The bottom end of the liquid reserve chamber 34 is provided with a No. 3 rod through hole 35 connecting to the external space. The outer circumferential surface of the longitudinal hollow column 31 is provided with a liquid docking channel 36 connecting one side of the liquid reserve chamber 34. A piston plate 37 capable of moving along its axial direction is placed inside the liquid compression chamber 33. The top of the piston plate 37... A second helical spring 38 in a compressed state is placed there. A longitudinal telescopic rod 39 passing through the third rod through the hole 35 is fixedly installed at the bottom end of the piston plate 37. A bottom fixing plate 310 is fixedly installed at the bottom end of the longitudinal telescopic rod 39. The bottom of the motor fixing seat 21 is fixedly installed on the corresponding upper surface of the bottom fixing plate 310. The cross-sectional shape of the third rod through the hole 35 is consistent with the cross-sectional shape of the longitudinal telescopic rod 39, both being polygonal structures. Furthermore, the cross-sectional dimensions of the third rod through the hole 35 match the cross-sectional dimensions of the longitudinal telescopic rod 39.

[0029] When in use, follow these steps: S1: Connect the liquid docking channel 36 to the liquid circuit of a hydraulic device that can control the direction of liquid flow and liquid pressure, and then fix the support base plate 13 in a horizontal position in the working position; S2: Move the built-in guide plate 112 to the lowest stroke of the compaction chamber 110, and then introduce the metal powder into the compaction chamber 110; S3: Start the drive motor 22, and its rotor will drive the longitudinal drive shaft 211 to rotate. Similarly, the longitudinal drive shaft 211 will drive the lower drive disk 29 to rotate. Due to the special structural shape of the guide rod 113, the hollow rotating shaft 24 and the upper driven disk 27 will remain stationary, while the rotating lower drive disk 29 will cause the hemispherical groove 28 and the hemisphere 210 to intermittently meet, overlap and separate. When the two separate and misalign, the protruding end of the hemisphere 210 abuts against the upper surface of the lower drive disk 29, forcing the hollow shaft 24 to move upward against the elastic force of the first helical spring 213; when the two meet and overlap, the hemisphere 210 is embedded in the hemispherical groove 28. Under the action of the return elastic force of the first helical spring 213 and its own gravity, the hollow shaft 24 moves downward rapidly. During the intermittent upward and downward movement, the built-in guide plate 112 will generate longitudinal vibration. This vibration can make the metal powder inside the compaction cavity 110 more compact. After the hemispherical groove 28 and the hemisphere 210 overlap for the last time, the drive motor 22 can be turned off, and then the metal powder is filled into the compaction cavity 110; S4: After the metal powder filling is completed, the hydraulic telescopic cylinder 16 is activated, and the compaction head 17 will move downward. When the compaction head 17 contacts the compaction cavity 110 When the internal metal powder is pressed, pressure is applied to the metal powder until it is die-cast into the desired finished product, thus completing the die-casting process. After die-casting, the hydraulic telescopic cylinder 16 controls the compaction head 17 to return to its original position. S5: Start the hydraulic equipment to allow liquid to enter the liquid compression chamber 33. Under liquid pressure, the piston plate 37 drives the bottom fixing plate 310 to move upward as a whole. The bottom fixing plate 310 sequentially pushes up the motor fixing seat 21, drive motor 22 and longitudinal drive shaft 211 fixed on it. The lower drive disc 29 at the top of the longitudinal drive shaft 211 then pushes the driven disc 27 and hollow rotating shaft 24 upward. Finally, the hollow rotating shaft 24 drives the guide rod 113 and the built-in guide plate 112 to move upward synchronously to demold. Finally, the built-in guide plate 112 will drive the die-cast finished product to move upward until the finished product is completely extracted.

10. A processing method for a powder metallurgy processing equipment, using the powder metallurgy processing equipment described in any one of claims 1-9, characterized in that: Includes the following steps, S1: Connect the liquid docking channel (36) to the liquid circuit of a hydraulic device that can control the direction of liquid flow and liquid pressure, and then fix the support base plate (13) in a horizontal position in the working position. S2: Move the built-in guide plate (112) to the lowest stroke position of the compaction chamber (110), and then introduce the metal powder into the compaction chamber (110); S3: Start the drive motor (22), its rotor will drive the longitudinal drive shaft (211) to rotate. Similarly, the longitudinal drive shaft (211) will drive the lower drive disk (29) to rotate. Due to the special structure of the guide rod (113), the hollow shaft (24) and the upper driven disk (27) will remain stationary, while the rotating lower drive disk (29) will cause the hemispherical groove (28) and the hemisphere (210) to intermittently meet, overlap and separate. When the two separate and misalign, the protruding end of the hemisphere (210) abuts against the upper surface of the lower drive disk (29), forcing the hollow shaft (24) to overcome the elastic force of the first helical spring (213) and move upward. When the two meet and overlap, the hemisphere (210) is embedded in the hemisphere groove (28). Under the action of the reset elastic force of the first helical spring (213) and its own gravity, the hollow shaft (24) moves downward rapidly. During the intermittent upward and downward movement, the built-in guide plate (112) will generate longitudinal vibration. This vibration can make the metal powder inside the compaction cavity (110) more compact. After the last overlap of the hemisphere groove (28) and the hemisphere (210) is completed, the drive motor (22) can be turned off, and then the metal powder is filled into the compaction cavity (110). S4: After the metal powder filling is completed, start the hydraulic telescopic cylinder (16), and the compaction head (17) will move downward. When the compaction head (17) contacts the metal powder inside the compaction chamber (110), it will exert pressure on the metal powder until the metal powder is die-cast into the desired finished product. The die-casting of the metal powder can be completed. After the die-casting is completed, the compaction head (17) is controlled to return to the starting position by the hydraulic telescopic cylinder (16). S5: Start the hydraulic equipment to allow liquid to enter the liquid compression chamber (33). Under liquid pressure, the piston plate (37) will drive the bottom fixed plate (310) to move upward. The bottom fixed plate (310) will indirectly drive the outlet rod (113) and the built-in guide plate (112) to move upward. Finally, the built-in guide plate (112) will drive the die-cast product to move upward until the product is completely discharged.
