Description

Technical Field

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

[0002] Metal powder metallurgy is a highly efficient, near-net-shape manufacturing technology that uses metal powder as raw material and processes such as forming and sintering to directly produce various parts.

[0003] Reference patent (CN202421257506.6) discloses a molybdenum-copper alloy powder forming device, relating to the field of metal powder forming and processing technology. The device includes a fixed frame, a hydraulic cylinder mounted on the top of the fixed frame, a base plate fixedly connected to the bottom of the fixed frame, a support plate fixedly connected to the top surface of the base plate, a thermoforming cavity formed on the top surface of the support plate, a pressure block fixedly connected to the bottom end of the telescopic rod of the hydraulic cylinder, and a feeding block movably connected to the top surface of the support plate. Limit plates are provided on both sides of the feeding block. The powder in the thermoforming cavity is thermoformed by pressing the pressure block. After thermoforming, the molybdenum-copper alloy block is removed from the thermoforming cavity and placed on the support plate. As the feeding block pushes, the molybdenum-copper alloy block moves onto a sieve, where the attached powder is collected into a collection trough, allowing the user to better collect excess powder for reuse and reducing waste of powder raw materials.

[0004] Based on the aforementioned patents, in the metal powder metallurgy process, powder pretreatment, uniform powder distribution, and pressing are key steps determining the quality of the final product. However, existing equipment mostly performs single-stage crushing of metal powders, lacking targeted secondary crushing and screening mechanisms. This results in uneven particle size distribution of the crushed powder, with some large, insufficiently crushed particles entering the forming cavity, directly affecting the density distribution and strength of the pressed blank. Furthermore, existing forming equipment often adopts a single-station operation mode, where feeding and pressing processes cannot be synchronized. After feeding into one forming cavity, it is necessary to wait for the pressing process to finish before feeding into another cavity. The subsequent feeding process involves significant waiting time between steps, resulting in low production efficiency. When metal powder is added to the thermoforming cavity, existing devices often fail to ensure uniform powder distribution within the cavity, leading to powder accumulation at the center point and significant thickness variations at different locations. This results in uneven density of the formed blank. Furthermore, different product specifications require thermoforming cavities of varying sizes, but existing powder dispersion devices have fixed structures, making it difficult to flexibly adjust the rotation diameter of the dispersion tube according to changes in the thermoforming cavity dimensions. Therefore, a metal powder metallurgy forming processing device and its processing technology are proposed. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a metal powder metallurgy forming and processing device and its processing technology. It solves the problem that most existing devices cannot guarantee the uniform distribution of powder in the cavity, and the powder tends to accumulate directly at the center point, resulting in large differences in powder thickness at different locations in the cavity, which in turn leads to uneven density of the formed blank. In addition, different specifications of products require thermoforming cavities of different sizes, but existing powder dispersion devices have fixed structures, making it difficult to flexibly adjust the rotation diameter of the dispersion tube according to the size changes of the thermoforming cavity.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a metal powder metallurgy forming and processing apparatus, comprising a mounting base, wherein the mounting base is provided with a mounting mechanism for metal powder metallurgy forming and processing, the mounting mechanism comprising: The feeding assembly includes a support slide rail fixed to the upper end of the mounting base.

[0011] Preferably, the shaking assembly includes a spring rod uniformly fixed on the upper surface of a first annular plate, a second annular plate fixed to the upper end of the spring rod, a filter plate fixedly connected inside the second annular plate, a connecting rod fixed to the outer wall of the drive shaft, a third annular plate fixed to the end of the connecting rod, a pair of second cams fixed to the lower end of the third annular plate, and a pair of first cams fixed to the upper end of the second annular plate, with the first cams and second cams arranged in a cross shape.

[0012] Preferably, the outer wall of the drive shaft is fixed with three sets of horizontal plates, and the second crushing rod is evenly distributed on the lower end face of the horizontal plates.

[0013] Preferably, the drive assembly includes a mounting bracket fixed to the upper end face of the mounting bracket, a second motor is disposed inside the mounting bracket, a gear is connected to the output end of the second motor, the vertical shaft is located at the upper end of the mounting bracket and is rotatably connected, and a toothed block is fixed to the outer wall of the vertical shaft, the toothed block being meshed with the gear.

[0015] This invention also provides a metal powder metallurgy forming process, comprising the following steps: Step 1: The powder is crushed by the first crushing rod, screened by the shaking of the filter plate, and then crushed again by the second crushing rod to obtain uniform fine powder. Step 2: The dispersion tube is made to move in a circular motion above the thermoforming cavity by the drive component, so as to evenly distribute the powder. Step 3: The dual-station switching is achieved through the push-up component. The pressing block presses down to solidify the powder into shape, while the other station feeds the material.

[0016] This invention provides a metal powder metallurgy forming and processing apparatus and its processing technology. Compared with the prior art, it has the following advantages: Firstly, in this invention, the first electric push rod pushes the mounting plate to slide on the support slide rail, so that the two sets of thermoforming cavities work alternately. When one thermoforming cavity is under the pressure block for pressing, the other thermoforming cavity is just under the feeding shell for feeding. The alternating work of the two sets of thermoforming cavities is achieved through the push assembly, with one for pressing and the other for feeding, which improves production efficiency.

[0017] Secondly, in this invention, the first motor is started, driving the drive shaft to rotate. The first crushing rod on the outer wall of the drive shaft performs preliminary crushing on the metal powder raw material entering the feed shell. The crushed powder falls onto the filter screen plate. Large particles of powder that do not pass through the filter screen plate are intercepted. At this time, the drive shaft drives the horizontal plate to rotate. The second crushing rod below the horizontal plate further crushes the coarse particles accumulated above the filter screen plate until the powder particle size becomes smaller and passes through the filter screen. Through the preliminary crushing by the first crushing rod and the secondary crushing by the second crushing rod on the large particles that do not pass through the filter screen, it is ensured that the powder particle size entering the molding process is uniform and fine, which improves the density and quality of the metallurgical product.

[0018] Thirdly, the second motor of this invention starts, driving the gear to rotate. The gear meshes with the toothed blocks on the outer wall of the vertical shaft, causing the vertical shaft to rotate. The vertical shaft drives the first movable rod to rotate. When the vertical shaft rotates, it drives the first and second movable rods to make circular motion. The dispersion tube sprinkles the powder into the mold through the circular motion, avoiding the powder from accumulating directly at the center point. This makes the powder distribution in the cavity highly uniform, and the density of the formed blank is uniform, reducing the risk of deformation and cracking during subsequent sintering. Furthermore, the precision threaded assembly composed of the worm shaft and the worm wheel shaft can precisely control the extension and retraction length of the second movable rod, thereby flexibly adjusting the rotation diameter of the dispersion tube. This allows the device to adapt to thermoforming cavities of different sizes, expanding the processing range of the equipment. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1 to 10 The present invention provides the following two technical solutions. A metal powder metallurgy forming and processing apparatus includes a mounting base 1, on which a mounting mechanism for metal powder metallurgy forming and processing is provided. The mounting mechanism includes: The feeding assembly includes a support slide rail 2 fixed to the upper end of the mounting base 1. The support slide rail 2 has a mounting plate 201 connected by a push assembly inside. The upper end of the mounting plate 201 has a pair of thermoforming cavities 205. The upper end of the mounting base 1 has a support frame 501. The upper part of the support frame 501 has a feeding shell 503. The inside of the feeding shell 503 has a drive shaft 505. The outer wall of the drive shaft 505 is fixed with a first crushing rod 506. The inner wall of the feeding shell 503 is fixed with a first annular plate 6. The upper end of the first annular plate 6 is a filter screen plate 603 connected by a shaking assembly. The surface of the filter screen plate 603 is provided with a second crushing rod 508. The dispersion component includes three sets of mounting brackets 7 fixed to the upper end of the support frame 501. One end of the mounting bracket 7 is provided with a vertical shaft 704 connected by a drive assembly. The upper end of the vertical shaft 704 is fixed with a first movable rod 706. The inside of the first movable rod 706 is provided with a second movable rod 8 connected by a threaded assembly. One end of the second movable rod 8 is provided with a dispersion tube 902.

[0023] In this embodiment of the invention, the push assembly includes a first electric push rod 3 fixed at one end of the mounting base 1. A mounting plate 201 is slidably connected inside a support slide rail 2, and the telescopic end of the first electric push rod 3 is fixedly connected to one side of the mounting plate 201. A guide rod 202 is provided inside the support slide rail 2, and the mounting plate 201 is slidably connected to the guide rod 202. A mounting seat 203 is provided at the upper end of the mounting plate 201. A connecting block 204 connected by threads is provided inside the mounting seat 203. A thermoforming cavity 205 is located on the connecting block 204. A locking hole 301 is provided at the edge of the mounting seat 203. A fixing bracket 302 is fixed at the edge of the support slide rail 2. A second electric push rod 303 is fixed in the output direction of the fixing bracket 302. The extension of the second electric push rod 303... A locking rod 304 is fixed at the retracted end, and a vertical rod 4 is fixed on the upper surface of the mounting base 1. A third electric push rod 401 is provided at the upper end of the vertical rod 4. A mounting block 402 is provided at the telescopic end of the third electric push rod 401, and the mounting block 402 is slidably connected to the vertical rod 4. A pressure block 403 is provided at the lower end of the mounting block 402. The two sets of thermoforming cavities 205 slide horizontally inside the support slide rail 2 through the push assembly. The thermoforming cavities 205 are set in two sets. When one thermoforming cavity 205 moves to the bottom of the pressure block 403, the other thermoforming cavity 205 is below the feeding shell 503 for feeding. After processing, one thermoforming cavity 205 moves, and the other thermoforming cavity 205 then moves to the bottom of the pressure block 403 to realize dual-station operation.

[0024] Specifically, the fourth electric push rod 5 is activated, and its telescopic end drives the support frame 501 to move up and down, adjusting the distance between the feeding shell 503 and the lower thermoforming cavity 205 to meet the feeding requirements; at the same time, the thermoforming cavity 205 is fixed on the mounting plate 201 through the threaded connection between the mounting base 203 and the connecting block 204 to ensure a stable installation. The process involves activating the first electric push rod 3, whose telescopic end pushes the mounting plate 201 to slide on the guide rod 202 of the supporting slide rail 2, causing the two sets of thermoforming cavities 205 on the mounting plate 201 to move horizontally. When one set of thermoforming cavities 205 moves below the feeding shell 503, the crushed and screened powder is uniformly conveyed into the thermoforming cavity 205 through the screw conveyor shaft 608. At the same time, the other set of thermoforming cavities 205 moves below the pressing block 403, activating the third electric push rod 401, whose telescopic end drives the mounting block 402 to slide along the vertical rod 4, pushing the pressing block 403 down to press and shape the powder in the thermoforming cavity 205. After the shaping is completed, the first electric push rod 3 pushes the mounting plate 201 to move again, switching the positions of the two sets of thermoforming cavities 205 to achieve synchronous feeding and shaping. Furthermore, when the thermoforming cavity 205 moves to the designated position, the second electric push rod 303 is activated, and its telescopic end pushes the locking rod 304 into the locking hole 301 on the edge of the mounting base 203, locking and fixing the mounting plate 201 and the thermoforming cavity 205 to prevent displacement during processing and ensure processing accuracy.

[0025] The thermoforming cavity 205 is threadedly connected to the mounting base 203 via the connecting block 204, which facilitates the disassembly and replacement of thermoforming cavities 205 of different specifications, adapting to the processing of powder metallurgy products of different sizes and shapes, and improving the versatility of the device. The fourth electric push rod 5 can adjust the height of the support frame 501 and the feeding shell 503 to adapt to thermoforming cavities 205 of different heights.

[0026] In this embodiment of the invention, three sets of fourth electric push rods 5 are fixed to the upper surface of the mounting base 1. The support frame 501 is fixedly connected to the telescopic end of the fourth electric push rod 5. An L-shaped plate 502 is fixed to the upper end of the support frame 501. The feeding shell 503 is fixedly connected to the L-shaped plate 502. A first motor 504 is provided at the upper end of the feeding shell 503. The drive shaft 505 is located at the output end of the first motor 504. The shaking component includes spring rods 601 uniformly fixed to the upper surface of the first annular plate 6. A second annular plate 602 is fixed to the upper end of the spring rod 601. The filter plate 603 is fixedly connected inside the second annular plate 602. The outer wall of the drive shaft 505 is fixed. A connecting rod 605 is fixed, and a third annular plate 606 is fixed to the end of the connecting rod 605. A pair of second cams 607 are fixed to the lower end of the third annular plate 606, and a pair of first cams 604 are fixed to the upper end of the second annular plate 602. The first cams 604 and the second cams 607 are arranged in a cross shape. Three sets of horizontal plates 507 are fixed to the outer wall of the drive shaft 505. The second crushing rods 508 are evenly distributed on the lower end face of the horizontal plates 507. The first crushing rods 506 perform preliminary crushing, and then the material is filtered through the filter plate 603. The material that is not sufficiently crushed is located above the filter plate 603 and is further crushed by the second crushing rods 508.

[0027] Specifically, metal powder is fed into the feed housing 503, and the first motor 504 is started. The output end of the first motor 504 drives the drive shaft 505 to rotate, and the first crushing rod 506 on the outer wall of the drive shaft 505 rotates synchronously to initially crush the fed metal powder. The crushed powder falls onto the filter plate 603. When the drive shaft 505 rotates, it drives the connecting rod 605, the third annular plate 606 and the second cam 607 to rotate. The second cam 607 cooperates with the first cam 604 at the upper end of the second annular plate 602 to squeeze the second annular plate 602. Combined with the elastic reset effect of the spring rod 601, the filter plate 603 is driven to shake up and down to achieve powder screening. Powder that meets the particle size requirements falls through the filter plate 603, while large particles of powder that are not sufficiently crushed remain above the filter plate 603. When the drive shaft 505 rotates, it drives the horizontal plate 507 to rotate synchronously. The second crushing rod 508 at the lower end of the horizontal plate 507 further crushes the large particles of powder on the filter screen plate 603 until the powder meets the particle size requirements and passes through the filter screen plate 603. A certain distance is reserved between the filter screen plate 603 and the second crushing rod 508 to avoid damage to the components caused by contact between the filter screen plate 603 and the second crushing rod 508 when the filter screen plate 603 shakes.

[0028] The second embodiment differs from the first embodiment in that: the drive assembly includes a mounting bracket 701 fixed to the upper surface of the mounting bracket 7, a second motor 702 is disposed inside the mounting bracket 701, a gear 703 is connected to the output end of the second motor 702, a vertical shaft 704 is rotatably connected to the upper end of the mounting bracket 7, a toothed block 705 is fixed to the outer wall of the vertical shaft 704, and the toothed block 705 is meshed with the gear 703; the threaded assembly includes a worm gear shaft 801 rotatably connected inside the first movable rod 706, a threaded shaft 802 is fixed inside the worm gear shaft 801, a worm shaft 803 is rotatably connected to the output direction of the first movable rod 706, the worm shaft 803 is meshed with the worm gear shaft 801, a second movable rod 8 is slidably connected inside the first movable rod 706, and the second movable rod 8 is threadedly connected to the threaded shaft 802. A third movable rod 9 is provided at one end of the movable rod 8. The second movable rod 8 and the third movable rod 9 are rotatably connected by a rotating shaft. An installation ring 901 is fixed at one end of the third movable rod 9. The dispersion tube 902 is located inside the installation ring 901 and is fixedly connected. A corrugated hose 903 is provided at the upper end of the dispersion tube 902, and one end of the corrugated hose 903 is connected to the lower end of the feed housing 503. A screw conveyor shaft 608 is provided at the lower end of the feed housing 503, and the screw conveyor shaft 608 is fixedly connected to the lower end of the drive shaft 505. The dispersion tube 902 moves in a circular motion above the thermoforming cavity 205 through the movable component, so that the material is more evenly dispersed into the thermoforming cavity 205 during feeding. The second movable rod 8 and the first movable rod 706 are telescopically adjustable to control the range of movement of the dispersion tube 902, thereby adjusting according to the size of the thermoforming cavity 205.

[0029] Specifically, based on the dimensions of the thermoforming cavity 205, the range of motion of the dispersion tube 902 is adjusted, the worm shaft 803 is rotated, and the worm shaft 803 meshes with the worm wheel shaft 801, driving the threaded shaft 802 inside the worm wheel shaft 801 to rotate. Since the second movable rod 8 is threadedly connected to the threaded shaft 802 and slidably connected to the first movable rod 706, when the threaded shaft 802 rotates, it drives the second movable rod 8 to extend and retract along the first movable rod 706, adjusting the total length of the first movable rod 706 and the second movable rod 8, thereby controlling the range of motion of the dispersion tube 902. Furthermore, after the powder inside the feed housing 503 is crushed and screened, it is conveyed to the dispersion tube 902 through the corrugated hose 903. The corrugated hose 903 can flexibly extend and retract with the movement of the dispersion tube 902 to avoid damage to the pipeline. The second motor 702 is started, and the output end of the second motor 702 drives the gear 703 to rotate. The gear 703 meshes with the tooth block 705 on the outer wall of the vertical shaft 704, driving the vertical shaft 704 to rotate. The vertical shaft 704 drives the first movable rod 706 at the upper end to rotate synchronously, which in turn drives the second movable rod 8, the third movable rod 9 and the dispersion tube 902 to perform circumferential motion, so as to evenly disperse the powder into the thermoforming cavity 205 and avoid powder accumulation.

[0030] Among them, the first and second electric linear actuators are model KM01, the third and fourth electric linear actuators are model DT300, the first motor is model 5IK60RGN-CFM, and the second motor is model 130ST-M04025.

[0031] This invention also provides a metal powder metallurgy forming process, comprising the following steps: Step 1: Uniform fine powder is obtained through crushing by the first crushing rod 506, shaking screening by the filter plate 603, and secondary crushing by the second crushing rod 508. Specifically, metal powder is fed into the feed shell 503, the first motor 504 is started, and the output end of the first motor 504 drives the drive shaft 505 to rotate. The first crushing rod 506 on the outer wall of the drive shaft 505 rotates synchronously to initially crush the fed metal powder. The crushed powder falls onto the filter plate 603. When the drive shaft 505 rotates, it drives the connecting rod 605, the third annular plate 606, and the second cam 607 to rotate. The second cam 607 cooperates with the first cam 604 at the upper end of the second annular plate 602 to squeeze the second annular plate 602. Combined with the elastic reset effect of the spring rod 601, the filter plate 603 shakes up and down to achieve powder screening. Powder that meets the particle size requirements falls through the filter plate 603, while large particles of powder that are not sufficiently crushed remain above the filter plate 603. Step 2: The dispersion tube 902 is made to move in a circular motion above the thermoforming cavity 205 by the driving component, so as to evenly distribute the powder. Step 3: The dual-station switching is achieved through the push assembly. The pressing block 403 presses down to solidify the powder into shape, while the other station feeds the material. The first electric push rod 3 is activated, and its telescopic end pushes the mounting plate 201 to slide on the guide rod 202 of the support slide rail 2, causing the two sets of thermoforming cavities 205 on the mounting plate 201 to move horizontally. When one set of thermoforming cavities 205 moves to below the feeding shell 503, the crushed and screened powder is uniformly conveyed into the thermoforming cavity 205 through the screw conveyor shaft 608. At the same time, the other set of thermoforming cavities 205 moves to below the pressing block 403, and the third electric push rod 401 is activated. Its telescopic end drives the mounting block 402 to slide along the vertical rod 4, pushing the pressing block 403 down to press and shape the powder in the thermoforming cavity 205. After the shaping is completed, the first electric push rod 3 pushes the mounting plate 201 to move again, switching the positions of the two sets of thermoforming cavities 205 to achieve synchronous feeding and shaping.

[0032] Working principle: First, according to the size of the thermoforming cavity 205, the height of the feeding shell 503 is adjusted by the fourth electric push rod 5, and the threaded shaft 802 is driven by rotating the worm shaft 803, so that the second movable rod 8 extends and retracts relative to the first movable rod 706, thereby setting the powder distribution radius of the dispersion tube 902. During processing, metal powder is fed into the feed housing 503, and the first motor 504 is started to drive the drive shaft 505 to rotate. The first crushing rod 506 on the drive shaft 505 performs initial crushing of the powder. At the same time, the drive shaft 505 drives the second cam 607 to rotate through the connecting rod 605, intermittently impacting the first cam 604. This causes the filter screen plate 603 to shake up and down through the spring rod 601 to screen the powder. Powder that meets the particle size falls down, while large particles that do not pass through are further crushed by the second crushing rod 508 below the horizontal plate 507 until they pass through the filter screen. The filtered powder is forced into the corrugated hose 903 through the screw conveyor shaft 608 and finally discharged from the dispersion tube 902. At this time, the second motor 702 is started, and the vertical shaft 704 is driven to rotate through the meshing of the gear 703 and the tooth block 705. This drives the first movable rod 706, the second movable rod 8 and the dispersion tube 902 at the end to make circular motion, so that the powder is evenly spread in the thermoforming cavity 205 located at the feeding station. At the same time, the first electric push rod 3 pushes the mounting plate 201 to slide along the guide rod 202, so that the other set of thermoforming cavities 205 filled with powder moves to the bottom of the pressing block 403. Then, the second electric push rod 303 pushes the locking rod 304 to insert into the locking hole 301 for positioning and locking. Subsequently, the third electric push rod 401 drives the mounting block 402 to press down, so that the pressing block 403 presses the powder in the cavity to form. After the forming is completed, the first electric push rod 3 pushes the mounting plate 201 to slide again, so that the positions of the two sets of thermoforming cavities 205 are swapped, so as to realize the synchronous and continuous operation of feeding and pressing.
