Description

Technical Field

[0001] This invention relates to the technical field of metal powder mixing, and more particularly to a mixing device for alloy proportioning of wear-resistant high-carbon and high-chromium steel forgings. Background Technology

[0002] In the production process of wear-resistant high-carbon and high-chromium steel forgings, the uniformity of the alloy composition directly affects the wear resistance, hardness and service life of the final product. High-carbon and high-chromium steel forgings are usually produced using powder metallurgy or precision casting processes, among which the mixing of metal powders is a key process that determines the consistency of alloy composition.

[0003] Metal powder mixing devices mainly employ single-shaft agitators, V-type mixers, or double-spiral conical mixers. However, for metal powders such as high-carbon and high-chromium steel, which have large specific gravity differences, irregular particle shapes, and are easily oxidized, a single-rotation direction agitator can easily cause the powder to undergo centrifugal stratification and swirling, resulting in light powder floating on the surface and heavy powder sinking to the bottom, leading to low mixing uniformity and affecting the compositional consistency of subsequent forgings.

[0004] During the mixing process, metal powder tends to adhere to the inner wall of the barrel and gradually dry into a hard shell. This adhesion and drying not only wastes materials but also increases stirring resistance, leading to localized overheating, accelerating powder oxidation, and even damaging the equipment. Conventional stirring is unlikely to effectively break up these clumps, resulting in component segregation zones in the finished product, which can cause cracks or reduced wear resistance in forgings.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. This invention, by setting up a mixing mechanism and adopting a coaxial dual-speed reverse rotation structure, achieves compound motion of opposite directions and different speeds by means of a planetary gear system between the blade mixing rod and the frame mixing rod, so that the light powder and the heavy powder form a multi-directional circulating convection in the barrel, which significantly improves the uniformity of metal powder mixing.

[0024] 2. By setting up a scraping adjustment mechanism, the present invention can actively adjust the fit between the mixing frame plate and the inner wall of the mixing barrel. When the arc-shaped scraping surface at the front end of the mixing frame plate contacts the barrel wall, it effectively scrapes off the metal powder adhering to the inner wall, avoiding material waste and wall drying, reducing metal powder friction overheating, and extending the service life of the equipment.

[0025] 3. By setting up a dispersing mechanism, when the scraping adjustment mechanism is activated, the air rod simultaneously drives the trigger tooth plate to move, driving the trigger gear and trigger wheel to rotate. Then, the dispersing plate is pulled out by the pull rope, so that the scraped agglomerated metal powder is dispersed by the impact of the dispersing plate the moment it is scraped away from the barrel wall, avoiding secondary agglomeration, significantly improving the efficiency of the mixing operation, shortening the overall mixing time, and reducing the amount of agglomeration in subsequent processing.

[0026] 4. This invention incorporates an anti-caking mechanism. A rotatable anti-caking sleeve is installed on the surface of the mixing drum, and a clumping outlet and anti-caking blades are installed on the mixing drum. When the mixing drum rotates, the anti-caking blades rotate with the drum, creating relative motion with the anti-caking sleeve. Metal powder clumps are flung out of the clumping outlet by centrifugal force. During mixing, the anti-caking blades cut and break up large clumps, which then re-enter the drum through the clumping outlet. Simultaneously, an independent motor drives the control drum and the anti-caking sleeve to rotate at different speeds via gear transmission. Combined with the periodic striking of the striking rod and striking head, clumping is prevented from blocking the discharge outlet, further improving the quality of the mixing operation.

[0043] Example 1

[0044] The support mechanism 100 includes a mixing support frame 101. A fixed cover 102 is fixedly connected to the left side of the top of the mixing support frame 101. A mixing powder discharge bucket 103 is fixedly connected to the left side of the inner wall of the fixed cover 102.

A mixing bucket 105 is fixedly connected to the right side of the control bucket 104. A bucket support frame 106 is movably connected to the right side of the surface of the mixing bucket 105 via a rotating shaft. The bottom of the bucket support frame 106 is fixedly connected to the top of the mixing support frame 101.

[0045] One embodiment of this example is as follows: The mixing mechanism 200 includes a mixing motor 201, which is located at the top right side of the mixing support frame 101. The left side of the mixing motor 201 is fixedly connected to the right side of the bucket support frame 106. An output rod 202 is fixedly connected to the output end of the mixing motor 201. An output disk 203 is fixedly connected to the left side of the output rod 202 through the bucket support frame 106. A synchronization rod 204 is fixedly connected to the left side of the output disk 203. Six synchronization rods 204 are provided and are equidistant from each other. The synchronous pulley 205 is fixedly connected to the left side of the synchronous rod 204. Synchronous teeth 206 are provided inside the synchronous pulley 205. Three planetary gears 207 are arranged equidistantly within the synchronous pulley 205. A hybrid gear 208 is located inside the planetary gears 207. The end of the planetary gear 207 furthest from the hybrid gear 208 is connected to the inner cavity of the synchronous pulley 205 via the synchronous teeth 206. The end of the planetary gear 207 furthest from the synchronous pulley 205 is connected to the hybrid gear 208. The surface of the gear 8 is meshed with the output disc 203. A gear limit frame 209 is movably connected to the left side of the output disc 203 via a rotating shaft. The left side of the gear limit frame 209 is movably connected to the right side of the mixing gear 208 and the planetary gear 207 via a rotating shaft. A vane-type mixing rod 210 is fixedly connected to the left side of the mixing gear 208. A mixing rod fixing seat 211 is movably connected to the left side of the vane-type mixing rod 210 via a rotating shaft. The left side of the mixing rod fixing seat 211 is fixedly connected to the left side of the inner wall of the mixing powder discharge tank 103. The surface of the vane-type mixing rod 210... A mixing blade 212 is fixedly connected, and two sets of mixing blades 212 are provided. A frame-type mixing rod 213 is fixedly connected to the left side of the synchronous pulley 205. There are six frame-type mixing rods 213 and they are evenly distributed. A mixing frame plate 214 is movably connected to the top of the frame-type mixing rod 213 through a rotating shaft. A movable rod 215 is movably connected to the left side of the bottom of the mixing frame plate 214 through a rotating shaft. A movable sleeve 216 is fixedly connected to the inner side of the movable rod 215. The inner cavity of the movable sleeve 216 is movably connected to the left side of the surface of the blade-type mixing rod 210.

[0046] A powder inlet hopper 106a is fixedly connected to the top right side of the bucket support frame 106, and a storage bucket 106b is provided at the bottom of the mixing and discharging bucket 103.

[0047] The front surface of the mixing frame plate 214 is provided with an arc-shaped scraping surface 214a, and the arc of the arc-shaped scraping surface 214a is consistent with the inner cavity of the mixing barrel 105.

[0048] The hybrid motor 201 is a servo motor. Its housing is bolted to the motor mounting plate on the right side of the barrel support frame 106. The output shaft of the hybrid motor 201 is fixed to the output rod 202 via a keyway. The output rod 202 passes horizontally through the sealed bearing seat on the right side of the barrel support frame 106. Its left end is welded to the center of the output disk 203. The output disk 203 is a disc-shaped cast steel part. Six threaded blind holes are evenly opened along the circumference on its left side. A synchronizing rod 204 is screwed into each blind hole. The synchronizing rod 204 is made of high-strength alloy steel. The left ends of the six synchronizing rods 204 pass through the corresponding through holes on the synchronizing wheel 205 and are fixed with lock nuts, thereby rigidly connecting the synchronizing wheel 205 and the output disk 203 into one unit. The synchronizing wheel 205 has a ring-shaped sleeve structure, and its inner wall is precision machined with an internal gear ring, i.e., synchronizing teeth. 206. Three planetary gears 207 are evenly distributed circumferentially in the inner cavity of the synchronizing gear 205. The number of teeth of each planetary gear 207 is the same as that of the synchronizing gear 206. The centers of the three planetary gears 207 are mounted on the gear limiting frame 209 through needle roller bearings. The mixing gear 208 is located in the center of the three planetary gears 207 and meshes with them. The center of the mixing gear 208 is connected to the vane mixing rod 210. The gear limiting frame 209 is triangular in shape. Its three corners are connected to the right ends of the rotating shafts of the three planetary gears 207 through bearings. Its center is connected to the right end of the rotating shaft of the mixing gear 208 through a bearing. At the same time, the right end face of the gear limiting frame 209 contacts the left side face of the output disk 203 through a thrust bearing to ensure the axial positioning and radial stability of the gear system during rotation.

[0049] The blade mixing rod 210 is a long rod with two sets of mixing blades 212 welded along its length. Each set of mixing blades 212 contains three blades to generate axial flow. The left end of the blade mixing rod 210 is connected to the mixing rod fixing seat 211 via a ceramic bearing. The mixing rod fixing seat 211 is welded to the central boss on the left inner wall of the mixing powder discharge tank 103 to ensure that the blade mixing rod 210 rotates without wobbling. Six frame mixing rods 213 are evenly welded along the circumference on the left end face of the synchronous pulley 205. The top of each frame mixing rod 213... A mixing frame plate 214 is hinged to a stainless steel pivot. A movable rod 215 is hinged to the bottom left side of the mixing frame plate 214 via the same pivot. The inner ends of all six movable rods 215 are welded to a common movable sleeve 216. The movable sleeve 216 is a sliding bearing sleeve made of copper alloy, and its inner hole forms a sliding fit with the surface of the blade-type mixing rod 210. The movable sleeve 216 can slide freely along the axial direction of the blade-type mixing rod 210 and rotates synchronously with the blade-type mixing rod 210. When the mixing motor 201 starts, the output rod 202 drives the output... The output disc 203 rotates counterclockwise. The output disc 203, via the synchronizing rod 204, drives the synchronizing wheel 205 and the six frame-type mixing rods 213 fixed to it to rotate counterclockwise synchronously. When the synchronizing wheel 205 rotates, the synchronizing teeth 206 on its inner wall drive three planetary gears 207 to rotate clockwise around their own axes. Simultaneously, the three planetary gears 207 revolve around the mixing gear 208. The planetary gears 207 then drive the mixing gear 208 to rotate clockwise, meaning the speed of the mixing gear 208 is higher than the speed of the synchronizing wheel 205. 208 drives the blade mixing rod 210 and mixing blade 212 to rotate clockwise at high speed, while the frame mixing rod 213 and mixing frame plate 214 rotate counterclockwise at low speed. During the mixing process, the high-speed counterclockwise mixing blade 212 forms a strong vortex and axial convection in the central area of ​​the barrel, pressing the light powder downward and throwing the heavy powder upward. Since the two are coaxial and rotate in opposite directions and at different speeds, the metal powder in the barrel is subjected to shear force and convection force that change in magnitude and direction, effectively avoiding centrifugal stratification and swirling phenomena caused by rotation in one direction.

[0050] By setting the mixing mechanism 200, coaxial dual-speed reverse rotation mixing can be achieved, which enables forced convection and shear dispersion of metal powder in the drum in the radial, circumferential and axial directions. This solves the problem of component stratification caused by light powder floating on the surface and heavy powder sinking to the bottom due to stirring in a single rotation direction in the prior art. It also solves the problem of low mixing uniformity caused by the powder spinning as a whole with the stirrer and weak relative motion, thus improving the operational reliability and mixing efficiency of the equipment.

[0051] Example 2

[0052] Based on Embodiment 1, this embodiment takes into account that metal powder is easily attached to the inner wall of the mixing tank 105 during the mixing operation and gradually dries into a hard shell, resulting in material waste, increased stirring resistance, local overheating and oxidation, and decreased mixing uniformity. Therefore, this embodiment provides a scraping adjustment mechanism 300. The scraping adjustment mechanism 300 includes an adjustment cylinder 301, which is located at the back end of the frame mixing rod 213. The top of the adjustment cylinder 301 is provided with a rod 302, and the top of the rod 302 is movably connected to a pull rod 303 through a rotating shaft. The top of the pull rod 303 is movably connected to the back end of the bottom of the mixing frame plate 214 through a rotating shaft.

[0053] The scraping adjustment mechanism 300 includes an adjusting cylinder 301, whose cylinder body is fixedly connected to the back end of the frame-type mixing rod 213 via a bracket. A piston rod 302 extends from the top of the adjusting cylinder 301. The piston rod 302 is a stainless steel piston rod, and its upper end has a radial through hole. A rotating shaft is mounted in this through hole via a bearing. This rotating shaft also passes through the shaft hole at the lower end of the pull rod 303, thereby hingedly connecting the top of the piston rod 302 to the lower end of the pull rod 303. The pull rod 303 is a strip-shaped connecting rod with shaft holes at both ends. The top of the pull rod 303 is also movably connected to the back end of the bottom of the mixing frame plate 214 via a rotating shaft. When the external pneumatic control valve group adjusts the air pressure... When compressed air is introduced into the rodless chamber of cylinder 301, the air rod 302 retracts inward. The air rod 302 pushes the back end of the bottom of the mixing frame plate 214 downward through the pull rod 303. According to the lever principle, the downward movement of the back end of the bottom of the mixing frame plate 214 will cause the arc-shaped scraping surface 214a at the top front end to swing outward around the fulcrum, so that the arc-shaped scraping surface 214a comes into contact with the inner wall of the mixing barrel 105. The arc-shaped scraping surface 214a adheres to the barrel wall for powerful scraping. By setting the scraping adjustment mechanism 300, the problem of metal powder on the barrel wall is solved, material waste is reduced, and the hard shell formed by drying on the wall is avoided, further improving the stability and reliability of the mixing operation.

[0054] Example 3

[0055] Based on Embodiment 2, this embodiment considers that the scraping adjustment mechanism 300 in Embodiment 2 can achieve dynamic adhesion and scraping between the mixing frame plate 214 and the inner wall of the mixing barrel 105, effectively removing the metal powder attached to the barrel wall. However, the metal powder scraped off the barrel wall often forms blocky or sheet-like lumps with a certain bonding strength. If these lumps are not dealt with in time after detaching from the barrel wall, they will roll and collide with each other in the barrel with the stirring motion of the mixing mechanism 200, further compacting and forming larger hard clumps. These clumps are not only difficult to break up by subsequent stirring, but will also affect the forging. To ensure quality, a dispersing mechanism 400 is provided in this embodiment. The dispersing mechanism 400 includes a trigger tooth plate 401, which is located at the front end of the air rod 302. A trigger gear 402 is movably connected to the back end of the frame mixing rod 213 and the position corresponding to the trigger tooth plate 401 via a rotating shaft. A trigger wheel 403 is fixedly connected to the left side of the trigger gear 402. A dispersing plate 404 is fixedly connected to the front end of the bottom of the mixing frame plate 214 via a spring plate. A pull rope 405 is fixedly connected to the surface of the trigger wheel 403. The end of the pull rope 405 away from the trigger wheel 403 is fixed to the bottom of the dispersing plate 404.

[0056] The dispersing mechanism 400 includes a trigger tooth plate 401, which is a long strip of metal plate with a straight toothed rack on the side facing the trigger gear 402. The trigger tooth plate 401 is vertically fixed to the front end face of the air rod 302 by two countersunk screws. The length direction of the trigger tooth plate 401 is parallel to the axis of the air rod 302. When the air rod 302 extends or retracts, the trigger tooth plate 401 moves vertically. At the back end of the frame-type mixing rod 213 and directly opposite the rack of the trigger tooth plate 401, a trigger gear 402 is movably connected via a rotating shaft. The front end of the bottom of the mixing frame plate 214 is fixedly connected to a dispersing plate 404 via a spring plate. The dispersing plate 404 is a heat-treated spring steel sheet. The length of the dispersing plate 404 matches the width of the mixing frame plate 214 and has an elastic reset function. When not subjected to external force, the dispersing plate 404 remains in a retracted state, tightly attached to the front end face of the bottom of the mixing frame plate 214.

[0057] One end of a pull rope 405 is fixedly connected to the surface of the trigger wheel 403. The pull rope 405 is made of high-strength aramid fiber braided rope. After the pull rope 405 is led out from the groove of the trigger wheel 403, it is fixed in the rope hole opened at the center of the bottom of the dispersing plate 404 and locked. When the adjusting cylinder 301 in the scraping adjustment mechanism 300 drives the air rod 302 to extend downward to perform the scraping action, the trigger tooth plate 401 fixed to the front end of the air rod 302 moves downward linearly. The rack on the trigger tooth plate 401 drives the trigger gear 402 meshing with it to rotate around its own axis. The trigger gear 402 drives the coaxial gear with it to rotate. The fixed trigger wheel 403 rotates synchronously. When the trigger wheel 403 rotates, its pull rope 405 wraps around and applies a downward pulling force to the bottom of the dispersing plate 404. This pulling force overcomes the elastic restoring force of the spring plate, forcing the spring plate to undergo elastic bending deformation, and causing the dispersing plate 404 to rotate outward from the front end of the bottom of the mixing frame plate 214. When the arc-shaped scraping surface 214a of the mixing frame plate 214 scrapes the attached metal powder clumps off the barrel wall, the dispersing plate 404, which is rotated outward, immediately impacts and disperses the clumps that have detached from the barrel wall, breaking the large clumps into small particles, so that they can re-participate in the main mixing.

[0058] By setting up a dispersing mechanism 400, the scraping and dispersing functions are linked, which solves the problem that the clumps of powder scraped off from the barrel wall are not processed in time and are rolled and compacted again to form larger hard clumps.

[0059] Example 4

[0060] Based on Example 1, this example considers that the mixing mechanism 200 in Example 1 can achieve coaxial dual-speed counter-rotation mixing of the blade mixing rod 210 and the frame mixing rod 213, effectively improving the macroscopic mixing uniformity of the metal powder. However, the problem still exists: in the metal powder used for high-carbon and high-chromium steel forgings, some fine powders, due to their large specific surface area and high surface energy, are prone to agglomeration during the mixing process due to electrostatic adsorption, mechanical extrusion, or trace amounts of moisture, forming soft or hard clumps ranging in size from hundreds of micrometers to several millimeters. Once these clumps form, they are often difficult to completely disperse by the shearing action of the agitator in the mixing tank alone, especially near the wall and corner areas of the mixing tank 105. Clumps in the stirring blind zone will continue to exist and grow. If these clumps are not effectively treated and directly... If the forging proceeds to the subsequent pressing or sintering process, compositional segregation zones and micro-defects will form inside the forging, leading to cracks, uneven hardness, or a significant decrease in wear resistance. Therefore, in this embodiment, an anti-agglomeration mechanism 500 is provided. The anti-agglomeration mechanism 500 includes an anti-agglomeration sleeve 501, which is located on the left side of the surface of the mixing tank 105. Both the left and right sides of the anti-agglomeration sleeve 501 are movably connected to sealing gaskets 502 via rotating shafts. The inner cavity of the sealing gasket 502 is fixedly connected to the surface of the mixing tank 105. An anti-agglomeration cutter 503 is fixedly connected to the surface of the mixing tank 105 and the inner side of the sealing gasket 502. Several anti-agglomeration cutters 503 are provided and distributed at equal intervals. The top and bottom of the mixing tank 105 and the inner side of the sealing gasket 502 are provided with agglomeration outlets 504.

[0061] An independent motor frame 101a is fixedly connected to the top of the back end of the hybrid support frame 101. An independent motor 101b is fixedly connected to the top of the independent motor frame 101a. A motor gear 101c is fixedly connected to the output end of the independent motor 101b. A motor gear ring 101d is provided on the surface of the control barrel 104. The back end of the motor gear ring 101d and the front end of the motor gear 101c are meshed. A sleeve gear 101e is movably connected to the right side of the top of the independent motor frame 101a through a rotating shaft. A sleeve gear ring 101f is provided on the surface of the anti-caking sleeve 501. The back end of the sleeve gear ring 101f and the front end of the sleeve gear 101e are meshed. A synchronous gear 101g is fixedly connected to the left side of the sleeve gear 101e. The bottom of the synchronous gear 101g and the top of the motor gear 101c are meshed.

[0062] A vertical rod 101h is fixedly connected to the top of the independent motor frame 101a. A striking head 101i is fixedly connected to the top of the vertical rod 101h. The front end of the striking head 101i contacts the surface of the anti-caking sleeve 501. A striking rod 101j is fixedly connected to the top of the left side of the sleeve gear 101e. The striking rod 101j and the vertical rod 101h are used together.

[0063] The clumping inlet 504 is set as an oblique circular opening, and the clumping inlet 504 is used in conjunction with the rotation of the mixing tank 105;

[0064] The anti-caking mechanism 500 includes an anti-caking sleeve 501, which is a cylindrical thin-walled stainless steel sleeve with an inner diameter larger than the outer diameter of the mixing tank 105, forming an annular gap. The anti-caking sleeve 501 is fitted onto the left side of the surface of the mixing tank 105 and is coaxially arranged with the mixing tank 105, allowing them to rotate relatively independently. Sealing gaskets 502 are installed on the left and right inner edges of the anti-caking sleeve 501, each gasket 502 being equipped with… The inner ring of the fluororubber rotary sealing ring with a metal skeleton is fixedly and sealed to the surface of the mixing tank 105. At the same time, the outer ring of the sealing gasket 502 forms a dynamic sliding seal with the inner wall of the anti-caking sleeve 501. The sealing gaskets 502 on the left and right sides, together with the inner wall of the anti-caking sleeve 501 and the outer wall of the mixing tank 105, form a closed annular processing cavity. This cavity is connected to the inside of the mixing tank 105 through the agglomeration outlet 504, but is isolated from the outside atmosphere to prevent metal powder leakage and oxidation.

[0065] On the surface of the mixing tank 105, within the area between the left and right sealing gaskets 502, several anti-clogging cutters 503 are fixedly connected. Each anti-clogging cutter 503 is a wedge-shaped blade made of cemented carbide, with its cutting edge facing the direction of rotation of the mixing tank 105. The multiple anti-clogging cutters 503 are evenly distributed along the circumference of the mixing tank 105. Each anti-clogging cutter 503 is fixed to a groove machined into the surface of the mixing tank 105 by countersunk screws, and the cutting edge of each anti-clogging cutter 503 protrudes from the outer surface of the mixing tank 105. Extending towards the inner wall of the anti-caking sleeve 501, the top and bottom of the mixing tank 105, which is also located in the area between the two sealing gaskets 502, are provided with agglomeration outlets 504. The opening direction is consistent with the predetermined rotation direction of the mixing tank 105. The inclined structure utilizes centrifugal force and material flow direction, making it easier for metal powder agglomerates in the tank to be thrown out of the agglomeration outlets 504 when the mixing tank 105 rotates, and enters the annular processing chamber. Normal fine powder is not easy to be thrown out due to its small mass and small centrifugal force, thus achieving selective separation of agglomerates.

[0066] An independent motor frame 101a is fixedly connected to the top of the back end of the mixing support frame 101. The horizontal section of the independent motor frame 101a is fixed to the crossbeam at the back end of the mixing support frame 101 by bolts. An independent motor 101b is fixedly connected to the top of the independent motor frame 101a by a motor mounting plate. The output end of the independent motor 101b is fixedly connected to a motor gear 101c by a flat key. The motor gear 101c is a steel spur gear. A motor gear ring 101d is fixedly fitted on the surface of the control barrel 104. The motor gear ring 101d is an internal gear ring structure. The back end of the motor gear ring 101d is machined with external teeth, which mesh with the front end of the motor gear 101c. When the independent motor 101b rotates, it drives the motor gear ring 101d and the control barrel 104 to rotate through the motor gear 101c, thereby driving the mixing barrel 105 fixedly connected to the control barrel 104 to rotate.

[0067] A sleeve gear 101e is movably connected to the top right side of the independent motor frame 101a via a rotating shaft and bearing seat. To the left of the sleeve gear 101e is a smaller diameter synchronous gear 101g. A sleeve gear ring 101f is fixedly fitted onto the surface of the anti-caking sleeve 501. The sleeve gear ring 101f is an external gear ring, and its inner wall is fixedly connected to the surface of the anti-caking sleeve 501 via a key and fastening screws. The external teeth at the back end of the sleeve gear ring 101f mesh with the driven gear at the front end of the sleeve gear 101e. A synchronous gear 101g is fixedly connected to the left side of the sleeve gear 101e. The synchronous gear 101g and the sleeve gear 101e... The shaft is integrally formed, and the bottom of the synchronous gear 101g meshes with the top of the motor gear 101c. The motor gear 101c of the independent motor 101b meshes with both the motor gear ring 101d and the synchronous gear 101g. The motor gear ring 101d drives the mixing drum 105 to rotate, while the synchronous gear 101g drives the anti-caking sleeve drum 501 to rotate through the sleeve gear 101e and the sleeve gear ring 101f. Because the meshing radii of the motor gear ring 101d and the synchronous gear 101g are different, there is a stable speed difference between the mixing drum 105 and the anti-caking sleeve drum 501, thus forming a continuous relative motion between the two.

[0068] To prevent the agglomerated powder ejected from the agglomeration outlet 504 from accumulating and clogging the annular processing chamber, this embodiment also includes a knocking anti-clogging structure: a vertically upward-pointing rod 101h is fixedly connected to the top of the independent motor frame 101a. The rod 101h is a round steel bar with a diameter of 10mm. Its lower end is connected to the independent motor frame 101a via threads, and its upper end is fixedly connected to a knocking head 101i. The front face of the knocking head 101i maintains slight contact with the surface of the anti-agglomeration sleeve 501. A radially extending striking rod 101j is fixedly connected to the top left side of gear 101e. Striking rod 101j is a short steel rod, its length allowing it to periodically strike the middle of vertical rod 101h during rotation. When the sleeve gear 101e rotates, the striking rod 101j moves in a circular motion, striking the vertical rod 101h once per revolution, generating vibration. This vibration is transmitted to the striking head 101i via the independent motor frame 101a, causing the striking head 101... The surface of the anti-caking sleeve 501 is periodically struck at the same frequency. The mechanical vibration generated by the striking prevents powder clumps from adhering stably to the inner wall of the anti-caking sleeve 501 and the annular processing cavity, allowing them to fall smoothly along the annular gap and re-enter the mixing tank 105. By setting up the anti-caking mechanism 500, a closed-loop anti-caking processing function of centrifugal ejection, cutting and dispersing, and anti-blocking backflow is realized. Through an independent motor 101b and gear transmission chain, the mixing tank 105 and the anti-caking sleeve 501 are driven to rotate at different speeds simultaneously, realizing the use of a single power source for multiple purposes, reducing equipment costs and energy consumption. It solves the problem that metal powder is prone to agglomeration during the mixing process and that it is difficult to completely disperse the powder in the tank. The agglomerates are separated into a dedicated cavity for centralized processing, which greatly improves the agglomeration dispersal efficiency. The striking anti-blocking structure effectively solves the problem of powder adhesion and blockage in the annular cavity, ensuring the long-term stable operation of the anti-caking mechanism 500 and further improving the working efficiency of metal powder mixing.

[0069] Working principle: The operator first weighs the high-carbon high-chromium steel and other alloy metal powders according to the ratio and puts them into the mixing tank 105 through the powder feeding hopper 106a fixedly connected to the top right side of the tank support frame 106. After the feeding is completed, the independent motor 101b is started. The independent motor 101b drives the motor gear ring 101d meshing with it to rotate through the motor gear 101c at its output end. The motor gear ring 101d drives the control tank 104 and the mixing tank 105 fixedly connected to it to rotate slowly, so that the powder in the tank is initially evenly distributed. The mixing motor 201 is started. The output shaft of the mixing motor 201 drives the output rod 202, the output disk 203 and the six synchronous rods 204 to rotate synchronously, thereby driving the synchronous wheel 205 to rotate at the first direction and the first speed.

[0070] When the synchronous wheel 205 rotates, it generates two power outputs: the first is frame stirring: the synchronous wheel 205 directly drives the six frame mixing rods 213 fixedly connected to its left side and the mixing frame plate 214 hinged to the rod end to perform large-range, low-frequency frame stirring with the same direction and speed, which pushes the metal powder near the inner wall of the barrel to move in the circumferential direction, preventing powder accumulation and centrifugal stratification.

[0071] The second-stage blade mixing: The synchronous teeth 206 on the inner wall of the synchronous wheel 205 drive three planetary gears 207 to rotate around their own axis and revolve around the center of the synchronous wheel 205. The planetary gears 207 then drive the central mixing gear 208 to rotate in the second direction and at the second speed. The mixing gear 208 drives the blade mixing rod 210 and the two sets of mixing blades 212 on its surface to rotate in opposite directions at high speed, forming a strong axial vortex and convection in the central area of ​​the mixing barrel 105, which significantly improves the mixing uniformity.

[0072] During the mixing process, metal powder easily adheres to the inner wall of the mixing drum 105 and gradually dries. At this time, the scraping adjustment mechanism 300 is activated, and the external pneumatic control valve group introduces compressed air into the rodless chamber of the adjusting cylinder 301. The air rod 302 retracts downward, and the air rod 302 pushes the back end of the bottom of the mixing frame plate 214 downward through the pull rod 303. According to the lever principle, the arc-shaped scraping surface 214a at the top front end of the mixing frame plate 214 swings outward around its hinge point with the frame mixing rod 213, closely adhering to the inner wall of the mixing drum 105. As the frame mixing rod 213 rotates, the arc-shaped scraping surface 214a continuously scrapes off the metal powder adhering to the inner wall. At the same time that the scraping adjustment mechanism 300 performs the wall scraping action, the dispersing mechanism 400 is triggered in conjunction, and the air rod 302 retracts downward. 2. When retracting downwards, the trigger tooth plate 401 fixed at its front end moves downwards in a straight line. The rack on the trigger tooth plate 401 drives the trigger gear 402 meshing with it to rotate. The trigger gear 402 drives the coaxial trigger wheel 403 to rotate synchronously. The trigger wheel 403 winds up the pull rope 405. The pull rope 405 overcomes the elastic force of the spring plate and pulls the dispersing plate 404 outwards from the front end of the bottom of the mixing frame plate 214. When the arc-shaped scraping surface 214a of the mixing frame plate 214 scrapes the clumps of powder off the barrel wall, the extended dispersing plate 404 immediately impacts and disperses the clumps that have detached from the barrel wall, breaking the large clumps into small particles so that they can re-participate in the main mixing.

[0073] While the mixing mechanism 200 is operating, the anti-caking mechanism 500 selectively processes larger clumps formed inside the container. At this time, the independent motor 101b drives two transmission paths simultaneously via the motor gear 101c. Due to the different meshing radii of the motor gear ring 101d and the synchronous gear 101g, a stable speed difference exists between the mixing container 105 and the anti-caking sleeve 501, resulting in continuous relative motion. When larger powder clumps form inside the mixing container 105, the clumps are affected by the rotation of the container. Under significant centrifugal force, when the agglomerates reach the location of the agglomeration outlet 504, due to the inclined circular opening of the outlet 504 and its orientation aligned with the rotation direction, the agglomerates are thrown out of the outlet 504 under the combined action of centrifugal force and the guiding force of the opening. They then enter the annular processing cavity enclosed by the outer wall of the mixing tank 105, the inner wall of the anti-agglomeration sleeve 501, and the sealing gasket 502. Once inside the annular cavity, due to the speed difference between the mixing tank 105 and the anti-agglomeration sleeve 501, the agglomerates are fixed to the surface of the mixing tank 105. The anti-caking blade 503 rotates with the drum, its wedge-shaped edge shearing, cutting, and impacting the clumps, breaking large clumps into fine powder. The broken powder moves along the annular gap under centrifugal force and gravity, simultaneously striking the anti-clogging structure. Vibration is transmitted through the striking head 101i to the anti-caking sleeve 501, preventing powder adhesion and clogging. Finally, the broken and dispersed fine powder falls back into the mixing drum 105 to participate in subsequent mixing. After the mixing operation is completed, the uniformly mixed metal powder passes through... The control tank 104 enters the mixing and powder discharge tank 103, and finally falls into the storage tank 106b for later use. Through the coordinated work of the support mechanism 100, mixing mechanism 200, scraping and adjusting mechanism 300, dispersing mechanism 400 and anti-agglomeration mechanism 500, the entire closed-loop process of efficient and uniform mixing of metal powder, dynamic scraping of the tank wall, immediate dispersing of scraped agglomerates, and centrifugal separation and external cutting and dispersing of large-sized agglomerates is realized, which significantly improves the quality and efficiency of alloy ratio mixing of wear-resistant high-carbon and high-chromium steel forgings.
