Description

Technical Field

[0001] This invention relates to the field of powder metallurgy technology, and in particular to a mixing device and method for powder metallurgy. Background Technology

[0002] Existing powder metallurgy mixing devices are represented by multi-directional motion mixers. Their structure mainly consists of a base, a drive system, a universal rocker arm mechanism, a uniquely shaped mixing barrel, and an electrical control system. By adding metal powder and additives that are mixed in proportion to the mixing barrel, and then setting the mixing time through the electrical control system, the drive system drives the universal rocker arm mechanism to make the mixing barrel move in three dimensions. The powder is cross-mixed in the barrel to achieve high uniformity mixing. After mixing, the uniformly mixed powder is discharged through the discharge valve. The whole process can avoid gravity segregation and stratification, and ensure that the components are evenly distributed.

[0003] In the actual mixing process of existing powder metallurgy mixing devices, it is often necessary to determine a variety of parameters to ensure the uniformity and stability of the mixture. These parameters generally include stirring speed, stirring time, and feed rate. Among them, the control of feed rate directly affects the mixing uniformity, equipment efficiency, and product quality. For example, when the loading of a V-type mixer exceeds 80%, the powder flowability is hindered, the mixing efficiency decreases by more than 30%, and it is easy to cause equipment jamming or motor overload. On the other hand, if the loading is too low (such as less than 30% of the volume), the powder will not have enough contact with the stirring paddle, the mixing dead zone will increase, and the uniformity will be significantly reduced. Therefore, it is generally necessary to adjust the feed rate.

[0004] However, the actual capacity of the mixing cylinder and the stirring structure of existing mixing equipment are mostly set in advance. When adding materials, it is necessary to control the mixing cylinder according to its actual capacity. If it is necessary to mix small or large quantities of materials, different specifications of devices need to be selected. As a result, the existing devices cannot adjust their mixing mechanism according to the required mixing dosage during actual mixing processing. They can only adjust the addition of materials according to the device's own requirements, which makes them inflexible in actual operation. Summary of the Invention

[0005] The purpose of this invention is to provide a mixing device and method for powder metallurgy, which can adjust its mixing mechanism according to the required mixing dosage during actual mixing processing through the provided components, thereby fully and evenly stirring and mixing the added specified dosage of materials, making it more flexible in actual operation.

[0010] The agitating component includes a sleeve and a detachable cutting and stirring plate. Each rotating main disk has multiple sleeves fixed on one side near the tilting disk.

The left and right cutting plates engage with the sleeves on the rotating main disks on both sides and pass through the corresponding tilting disks. The middle cutting plate is fixedly connected to the cutting plates on both sides through the connecting sleeve and bolts.

[0011] The driving component includes a worm gear, a worm, and a drive motor. The worm gear is fixedly sleeved on the double-ended lead screw. The worm engages with the worm gear and is rotatably mounted inside the rotating main disk. The output shaft of the drive motor is connected to the worm, and the drive motor is fixedly mounted on one side of the rotating main disk.

[0012] The synchronization component includes a rotating shaft, a lap bevel gear, a drive shaft, a drive bevel gear, and a shaft drive mechanism.

Two lap bevel gears are fixedly mounted on the upper and lower sides of each rotating shaft, with the lap bevel gear on the upper side meshing with the external bevel gear on the corresponding side. The drive shaft is rotatably mounted on the bottom of the support base. Two drive bevel gears are fixed on both sides of the drive shaft, meshing with the lap bevel gear at the bottom of the corresponding side of the rotating shaft.

[0018] The actual stirring space inside the mixing tank is adjusted by sliding the inner sliding frame and the tilting plate.

[0019] After the internal structure of the mixing tank is adjusted, metallurgical powder is added into the mixing tank.

[0020] The outer ring drive mechanism drives the mixing main tank to rotate in the forward direction, while the co-rotating component drives the two rotating main disks inside the mixing main tank to rotate in the opposite direction.

[0021] The metallurgical powder in the mixing tank is fully mixed by the counter-rotation of the two rotating main discs on both sides in conjunction with the stirring component and the forward rotation of the mixing tank.

[0022] This invention discloses a mixing device and method for powder metallurgy. In actual operation, the total amount of metallurgical powder to be mixed is estimated. Then, based on the estimated result, the sliding inner frame and the tilting disk on both sides of the mixing main tank are moved by the pushing component. The actual stirring space inside the mixing main tank is adjusted by the sliding inner frame and the tilting disk. After the internal structure of the mixing main tank is adjusted, the metallurgical powder is added into the mixing main tank. The outer ring drive mechanism drives the mixing main tank to rotate forward, while the rotating component drives the rotating main disks on both sides of the mixing main tank to rotate in the opposite direction. The counter-rotation of the rotating main disks on both sides, together with the stirring component and the forward rotation of the mixing main tank, fully mixes the metallurgical powder in the mixing main tank. This allows the mixing mechanism to be adjusted according to the required mixing dosage during actual mixing, thereby fully and uniformly mixing the added specified dosage of material, resulting in greater flexibility in actual operation.

Detailed Implementation

[0035] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0036] In the description of this invention, it should be understood that "a plurality of" means two or more, unless otherwise explicitly specified.

[0037] Please see Figures 1 to 9This invention provides a mixing device and method for powder metallurgy: comprising a support base 101, a main mixing tank 102, an outer ring drive mechanism 103, and a mixing assembly. The mixing assembly includes a guide rail 104, a sliding inner frame 105, a tilting disc 106, a rotating main disc 107, a pushing component, a co-rotating component, and a stirring component. The pushing component includes a through guide rod 201, an inner slide 202, a connecting piece 203, a double-ended lead screw 204, and a drive component. The co-rotating component includes a sleeved gear ring 301, a connecting gear shaft 302, an external bevel gear 303, and a synchronization component. The stirring component includes a sleeve 401 and a detachable cutting and stirring plate 402. The drive component includes a worm gear 501, a worm 502, and a drive motor. Machine 503, the synchronization component includes a rotating shaft 601, a lap bevel gear 602, a drive shaft 603, a drive bevel gear 604, and a shaft drive mechanism 605. The aforementioned solution solves the problem that the actual capacity of the mixing cylinder 701 and the stirring structure of existing mixing equipment are mostly set in advance. When adding materials, it is necessary to control according to the actual capacity of the mixing cylinder 701. If it is necessary to mix small or large amounts of materials, different specifications of devices need to be selected. As a result, the existing devices cannot adjust their mixing mechanism according to the required mixing dosage during actual mixing processing. They can only adjust the addition of materials according to the device's own requirements, resulting in low flexibility in actual operation.

[0038] Furthermore, the mixing main tank 102 is rotatably mounted on the support base 101, the outer ring drive mechanism 103 is disposed on the support base 101, the guide rail 104 is fixedly mounted inside the mixing main tank 102, and two sliding inner frames 105 are slidably mounted on both sides inside the mixing main tank 102, respectively. The sliding inner frames 105 are slidably connected to the guide rail 104, and each sliding inner frame 105 has a rotating disk 106 rotatably mounted inside it. Two rotating main disks 107 are rotatably mounted inside the mixing main tank 102. On one side, both rotating main disks 107 are rotatably connected to the support base 101, and two sliding inner frames 105 are disposed between the two rotating main disks 107. Each rotating main disk 107 is provided with a pushing component for driving the designated flipping disk 106 and the sliding inner frame 105. The rotating component is connected to the support base 101 for driving the two rotating main disks 107. The stirring component is connected to the rotating main disks 107 for stirring and mixing the raw materials in the mixing tank 102.

[0039] Specifically, the support base 101 is provided with a corresponding bracket structure for mounting the mixing main tank 102. The mixing main tank 102 is driven by the outer ring drive mechanism 103. The outer ring drive mechanism 103 consists of a corresponding gear meshing mechanism, a reduction gearbox, and a drive element. The gear meshing with the gear ring, the reduction gearbox, and the drive element drive the entire mixing main tank 102 to rotate on the support base 101.

[0040] The guide rail 104 is fixedly installed inside the mixing main tank 102. The sliding inner frame 105 cooperates with the guide rail 104 through the provided guide groove. The sliding inner frame 105 is a circular structure. The outer side of the sliding inner frame 105 abuts against the inner wall of the mixing main tank 102. The provided guide rail 104 can limit the sliding inner frame 105 to prevent it from rotating when moving inside the mixing main tank 102. At the same time, it can also ensure the single movement cooperation between the sliding inner frame 105 and the inner wall of the mixing main tank 102, so that the sliding inner frame 105 can slide more stably inside the mixing main tank 102.

[0041] The tilting plate 106 is rotatably mounted inside the sliding inner frame 105. The tilting plate 106 and the sliding inner frame 105 can form an inner baffle structure inside the mixing main tank 102. The size of the mixing space inside the mixing main tank 102 can be adjusted by moving the sliding inner frames 105 and the tilting plate 106 on both sides.

[0042] Two rotating main disks 107 are respectively rotatably disposed on both sides of the mixing main tank 102. A corresponding rotating platform is also provided on the outer side of the rotating main disk 107 and connected to the support seat 101, so that the rotating main disk 107 can rotate on the support seat 101 and can also rotate with the mixing main tank 102. When the rotating main disk 107 rotates, the provided pushing component can drive the tilting disk 106 and the corresponding stirring component to rotate together, thereby stirring and mixing the raw materials inside the mixing main tank 102.

[0043] In actual operation, the total amount of metallurgical powder to be mixed is estimated. Then, based on the estimated result, the sliding inner frame 105 and the tilting disk 106 on both sides of the mixing main tank 102 are moved by the pushing component. The actual stirring space inside the mixing main tank 102 is adjusted by the sliding of the sliding inner frame 105 and the tilting disk 106. After the internal structure of the mixing main tank 102 is adjusted, the metallurgical powder is added into the mixing main tank 102, and the mixing main tank 102 is driven by the outer ring drive mechanism 103. The mixing tank rotates in the forward direction, while the rotating component drives the two rotating main disks 107 on both sides of the mixing tank 102 to rotate in the reverse direction. The reverse rotation of the two rotating main disks 107, in conjunction with the stirring component and the forward rotation of the mixing tank 102, fully mixes the metallurgical powder in the mixing tank 102. This allows the mixing mechanism to be adjusted according to the required mixing dosage during actual mixing, thereby fully and evenly mixing the added material at the specified dosage, resulting in greater flexibility in actual operation.

[0044] Furthermore, the two ends of the through guide rod 201 are respectively fixedly connected to the two rotating main disks 107, and the through guide rod 201 passes through the two flip disks 106; the inner slide 202 is slidably installed in each of the rotating main disks 107; one side of the adapter 203 is rotatably connected to the inner slide 202, and the other side of the adapter 203 is rotatably connected to the flip disk 106 on a designated side; the double-ended lead screw 204 is threadedly connected to the inner slide 202 and rotatably installed in the rotating main disk 107; the driving component is connected to the rotating main disk 107 and is used to drive the double-ended lead screw 204.

[0045] Furthermore, the worm gear 501 is fixedly sleeved on the double-ended lead screw 204; the worm 502 cooperates with the worm gear 501 and is rotatably installed inside the rotating main disk 107; the output shaft of the drive motor 503 is connected to the worm 502, and the drive motor 503 is fixedly installed on one side of the rotating main disk 107.

[0046] In this embodiment, when in use, the two ends of the through guide rod 201 are respectively fixed to the sides of the two rotating main disks 107. There are two through guide rods 201 in total. At the same time, the flip disk 106 is provided with guide holes for the through guide rods 201 to cooperate with. The through guide rods 201 can guide the sliding of the flip disk 106, and at the same time, the flip disk 106 can rotate better with the rotating main disk 107.

[0047] The rotating main disk 107 has corresponding grooves inside for installing the inner slide 202. Guide cylinders are also provided in the grooves to ensure the stable up-and-down sliding of the inner slide 202. Each rotating main disk 107 has two symmetrically sliding inner slides 202. The two inner slides 202 are respectively connected to the threads on both sides of the double-ended lead screw 204. The threads on both sides of the double-ended lead screw 204 rotate in opposite directions. A worm gear 501 is fixedly sleeved at the middle end of the double-ended lead screw 204. The worm gear 501 cooperates with the worm 502, which is driven by the drive motor 503. When the drive motor 503 drives the worm 502 to rotate, the worm 502 drives the worm gear 501 and the double-ended lead screw 204 to rotate, thereby driving the two inner slides 202 to unfold or close to each other through the rotation of the double-ended lead screw 204.

[0048] The inner slide 202 is connected to the corresponding rotating disk 106 via the adapter 203. Both connecting joints of the adapter 203 can rotate normally. When the two inner slides 202 inside the rotating main disk 107 expand to both sides, the adapter 203 will continuously squeeze the rotating disk 106 under the drive of the inner slides 202, thereby pushing the rotating disk 106 away from the rotating main disk 107. When the two inner slides 202 approach each other synchronously, the adapter 203 will pull the rotating disk 106 closer to the rotating main disk 107, so that the operator can drive the rotating disk 106 and the sliding inner frame 105 by controlling the relative movement of the two inner slides 202.

[0049] Furthermore, each of the rotating main disks 107 is fixedly fitted with a sleeve toothed ring 301; two connecting toothed shafts 302 are respectively rotatably mounted on both sides of the support base 101, and the gears provided on the two connecting toothed shafts 302 respectively cooperate with the sleeve toothed rings 301 on both sides; each connecting toothed shaft 302 is fixedly mounted with an external bevel gear 303; the synchronization component is connected to the support base 101 and is used to cooperate with the external bevel gear 303 to synchronously drive the connecting toothed shafts 302 on both sides.

[0050] Furthermore, the two rotating shafts 601 rotate on both sides of the support base 101 respectively; two overlapping bevel gears 602 are fixedly installed on the upper and lower sides of each rotating shaft 601, and the overlapping bevel gear 602 on the upper side of the rotating shaft 601 meshes with the external bevel gear 303 on the corresponding side; the drive shaft 603 is rotatably installed on the bottom of the support base 101; two drive bevel gears 604 are fixed on both sides of the drive shaft 603 respectively, and the drive bevel gears 604 on both sides mesh with the overlapping bevel gear 602 at the bottom of the rotating shaft 601 on the corresponding side; the shaft drive mechanism 605 is disposed on the support base 101 and is used to drive the drive shaft 603.

[0051] In this embodiment, each of the rotating main disks 107 connected to the support base 101 is fixedly fitted with a sleeve gear ring 301. The sleeve gear ring 301 meshes with the gear of the connecting gear shaft 302. The connecting gear shaft 302 is connected to the rotating shaft 601 through the external bevel gear 303 and the overlapping bevel gear 602 at the top of the rotating shaft 601. The rotating shaft 601 is connected to the drive shaft 603 through the overlapping bevel gear 602 at the bottom of the rotating shaft 601 and the drive bevel gear 604. In this way, the rotating main disks 107 on both sides can be connected by the corresponding gear sets and bevel gear sets, so that the rotating main disks 107 on both sides can rotate synchronously together.

[0052] To avoid unnecessary structures inside the mixing tank 102 affecting the normal mixing and discharge of raw materials, the through guide rod 201 is made relatively small. If the rotating main disk 107 on one side is driven to rotate synchronously through the through guide rod 201, the force borne by the through guide rod 201 will be large. Therefore, the above-mentioned driving structure can drive the rotating main disks 107 on both sides to rotate synchronously, which can greatly reduce the pressure on the corresponding connecting structure and ensure the long-term stable operation of the corresponding connecting structure.

[0053] It should be noted that, since the transmission direction of the bevel gear set is related to the setting position of the two bevel gears when the bevel gears are engaged, in order to ensure that the rotation direction of the rotating main disks 107 on both sides is consistent, the bevel gear sets that are engaged need to be adjusted so that the rotating main disks 107 on both sides can rotate synchronously more stably.

[0054] The drive shaft 603 is driven by the shaft drive mechanism 605, which consists of a gear set and a drive element. The drive element drives the corresponding gear to rotate, and then the gear set drives the drive shaft 603. When the drive shaft 603 rotates, the drive bevel gears 604 on both sides of the drive shaft 603 drive the overlapping bevel gears 602 at the bottom of the rotating shafts 601 on both sides to rotate, thereby synchronously driving the rotating shafts 601 on both sides. Then, the rotating main disks 107 on both sides are driven by the cooperation between the corresponding gears and the bevel gears.

[0055] Furthermore, each of the rotating main disks 107 has multiple inserts 401 fixed on one side near the flip disk 106; the detachable cutting and stirring plate 402 cooperates with the inserts 401 on the two rotating main disks 107 on both sides respectively. The detachable cutting and stirring plate 402 is composed of three cutting plates 4021 and connecting sleeves 4022. The left and right cutting plates 4021 cooperate with the inserts 401 on the rotating main disks 107 on both sides respectively, and pass through the corresponding flip disks 106. The middle cutting plate 4021 is fixedly connected to the cutting plates 4021 on both sides through the connecting sleeves 4022 and bolts.

[0056] In this embodiment, multiple inserts 401 are fixed on the sides of the two rotating main disks 107 that cooperate with the flip disk 106. Each insert 401 has an insertion hole. The cutting plate 4021 of the detachable cutting and stirring plate 402 is adapted to the insertion hole of the insert 401. The flip disk 106 is provided with a cutting groove for cooperating with multiple sets of cutting plates 4021, so that the flip disk 106 can slide on multiple sets of cutting plates 4021.

[0057] By employing the three-section detachable cutting and stirring plate 402, a stirring structure can be formed within the mixing main tank 102. The detachable cutting and stirring plate 402 rotates along with the tilting plate 106 and the rotating main plate 107 to continuously disperse and mix the raw materials within the mixing main tank 102. Simultaneously, the tilting plates 106 on both sides can slide on the cutting plates 4021 on the left and right sides of the detachable cutting and stirring plate 402. This ensures the integrity of the stirring structure inside the mixing main tank 102 without affecting the movement and adjustment of the tilting plates 106 and the corresponding mechanisms on both sides.

[0058] The three-section detachable cutting and stirring plate 402 allows for quick disassembly without affecting the normal adjustment of the two side rotating discs 106. The detachable cutting and stirring plate 402 connects the left and right cutting plates 4021 and the middle slicer via the connecting sleeve 4022 and bolts. Therefore, when disassembling the detachable cutting and stirring plate 402, it is only necessary to first move the two side rotating discs 106 and the sliding inner frame 105 to their extreme positions, so that the corresponding side rotating disc 106 and sliding inner frame 105 can be as close as possible to the corresponding rotating main disc 107, facilitating subsequent operation. The slice embedded in the flip plate 106 is pulled out, and then the connecting sleeve 4022 is removed so that the middle slice can be removed first, and then the slices on both sides can be pulled out from the insert sleeve 401 and the corresponding flip plate 106. Because when mixing and stirring metallurgical powder, the stirring mechanism body is easily replaced or maintained regularly due to friction of metal particles, etc. Therefore, the above-mentioned detachable cutting and stirring plate 402 can facilitate the user to quickly disassemble the entire stirring mechanism. Moreover, when considering the quick disassembly of the stirring structure, it will not affect the adjustment of the size of the stirring area inside the mixing main tank 102.

[0059] Preferably, the mixing assembly provided by the present invention further includes a material cylinder 701, a side sealing frame 702, a side sealing cylinder 703, a bottom sealing component, and an inner plate mixing component. The bottom sealing component includes a bottom sealing plate 801, a guide sleeve frame 802, a side abutment plate 803, and a driving cylinder 804. The inner plate mixing component includes a connecting bracket 901, an inner plate insert 902, an adjusting screw 903, and a screw drive mechanism 904.

[0060] Furthermore, the material cylinder 701 is fixedly installed on the mixing main tank 102; the side sealing frame 702 is slidably installed on the side of the support seat 101 near the material cylinder 701 and connected to the material cylinder 701; the output end of the side sealing cylinder 703 is connected to the side sealing frame 702, and the side sealing cylinder 703 is fixedly installed on the support seat 101; the bottom sealing component is connected to the mixing main tank 102 and is used to adjust the overall tank structure of the mixing main tank 102; the inner plate mixing component is connected to the mixing main tank 102 and is used to stir and disperse the raw materials in the mixing main tank 102.

[0061] In this embodiment, the material cylinder 701 is adapted to the material trough of the mixing main tank. The material cylinder 701 enables feeding and discharging. Since the mixing main tank 102 can rotate on its own, the material cylinder 701 can serve as a feeding channel when facing upwards and as a discharging channel when facing downwards. The side sealing frame 702 is slidably installed on the side of the mixing main tank 102 where the material cylinder 701 is located. The side sealing frame 702 is adapted to the side guide groove of the material cylinder 701. The left and right movement of the side sealing frame 702 can cover the opening of the material cylinder 701, thereby controlling the opening of the material cylinder 701. The side sealing frame 702 is driven by the side sealing cylinder 703.

[0062] Furthermore, the bottom sealing plate 801 is connected to the mixing main tank 102; the guide sleeve 802 is fixedly installed on one side of the mixing main tank 102; the side abutment plate 803 is slidably installed on the guide sleeve 802; the output end of the driving cylinder 804 is connected to the side abutment plate 803, and the driving cylinder 804 is fixedly installed on one side of the mixing main tank 102.

[0063] In this embodiment, the bottom sealing plate 801 is adapted to the opening at the bottom of the mixing main tank 102. The bottom sealing plate 801 is blocked and limited by the sliding of the side abutment plates 803. When the two side abutment plates 803 cover the bottom of the bottom sealing plate 801, the bottom sealing plate 801 will be completely embedded in the opening of the mixing main tank 102. When the two side abutment plates 803 are moved away from the sides of the bottom sealing plate 801, the bottom sealing plate 801 can be pulled out from the opening of the mixing main tank 102. The two sets of side abutment plates 803 cooperate with the guide sleeves 802 arranged on both sides of the mixing main tank 102. The side abutment plates 803 are driven by the driving cylinders 804. Each side abutment plate 803 is equipped with two driving cylinders 804. Each pair of driving cylinders 804 used to drive the same side abutment plate 803 is equipped with a corresponding synchronous driving module for control, so as to ensure that the two driving cylinders 804 stably drive the same side abutment plate 803.

[0064] The bottom of the bottom sealing plate 801 is also provided with a socket sleeve. The socket sleeve allows operators to easily disassemble and install the bottom sealing plate 801 using lifting tools such as forklifts. By removing the bottom sealing plate 801, the opening of the mixing main tank 102 can be opened, which facilitates the user to maintain and replace the internal structure of the mixing main tank 102. This is mainly to facilitate the user to disassemble and replace the internal detachable cutting and stirring plate 402.

[0065] Furthermore, the connecting bracket 901 is fixedly installed on one side of the mixing main tank 102; the inner plate insert 902 is slidably installed on the connecting bracket 901 and penetrates the outer wall of the mixing main tank 102; the adjusting screw 903 is threadedly connected to the inner plate insert 902 and rotatably installed on the connecting bracket 901; the screw drive mechanism 904 is connected to the connecting bracket 901 and is used to drive the adjusting screw 903.

[0066] In this embodiment, during use, the connecting brackets 901 are fixed on both sides of the mixing main tank 102, and each connecting bracket 901 is also provided with an inner plate insert 902. The inner plate insert 902 is provided with multiple insertable stirring blades, which are adapted to the cutting slots provided on the side of the mixing main tank 102. By inserting the stirring blades into the mixing main tank 102 through the inner plate insert 902, combined with the rotation of the mixing main tank 102 itself, the mixing main tank 102 can be rotated. The internal raw materials are more evenly and thoroughly mixed, which to some extent compensates for the agitation blind area of ​​the detachable cutting and stirring plate 402. When the tilting plate 106 and the sliding inner frame 105 need to slide inside the mixing main tank 102, the inner plate insert 902 can move outward, thereby retracting the inserted stirring plate of the inner plate insert 902 into the inner wall of the mixing main tank 102, avoiding interference with the normal adjustment of the tilting plate 106 and the sliding inner frame 105.

[0067] The inner plate bracket 902 is driven by the adjusting screw 903 and the screw drive mechanism 904. The inner plate bracket 902 is provided with corresponding threaded hole plates. The adjusting screw 903 cooperates with the threaded hole plates of the inner plate bracket 902. The screw drive mechanism 904 is used to drive the adjusting screw 903. The screw drive mechanism 904 has the same structural principle as the shaft drive mechanism 605. Both of them use a gear set to cooperate with the drive element to drive the corresponding rod. In this way, the inner plate bracket 902 can be driven by the rotation of the adjusting screw 903.

[0068] Since the inserting stirring blades of the inner plate bracket 902 are needed to better ensure the mixing of raw materials inside the mixing tank 102, in order to avoid collisions and interference between the inner plate bracket 902 and the adjusted tilting disc 106 and the sliding inner frame 105, the movement scheme of the tilting disc 106 and the sliding inner frame 105 needs to be adjusted according to the design of the inserting stirring blades on the inner plate bracket 902. This ensures that the tilting disc 106 and the sliding inner frame 105 can be positioned between the two inserted stirring blades after each adjustment, thereby not only ensuring the adjustability of the mixing area inside the mixing tank 102 but also ensuring the mixing quality inside the mixing tank 102.

[0069] Please see Figure 10 A mixing method for powder metallurgy, employing the aforementioned mixing apparatus for powder metallurgy, includes the following steps:

[0070] S1: Estimate the total amount of metallurgical powder to be mixed, and then move the sliding inner frame 105 and the tilting plate 106 on both sides of the mixing main tank 102 according to the estimate result by pushing the component.

[0071] S2: The actual stirring space inside the mixing tank 102 is adjusted by sliding the sliding inner frame 105 and the tilting plate 106;

[0072] S3: After the internal structure of the mixing tank 102 is adjusted, metallurgical powder is added into the mixing tank 102;

[0073] S4: The outer ring drive mechanism 103 drives the mixing main tank 102 to rotate in the forward direction, while the rotating component drives the two rotating main disks 107 inside the mixing main tank 102 to rotate in the reverse direction.

[0074] S5: The metallurgical powder in the mixing tank 102 is fully mixed by the counter-rotation of the rotating main disks 107 on both sides in conjunction with the stirring component and the forward rotation of the mixing tank 102.

[0075] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
