DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings of the specification. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0033] Embodiment 1: Combination Figure 1-Figure 10 As shown, the present invention provides a technical solution: a molding process of magnetic material powder, specifically comprising the following steps:

[0034] Step 1: Material selection and preparation: It is necessary to select suitable magnetic powder materials as raw materials, such as magnetic metals or alloys such as iron, nickel, and cobalt, mix the raw materials with other auxiliary materials (such as reinforcing agents, lubricants, etc.) in a certain proportion, and grind them. The purpose of this step is to grind the mixture into fine particles to increase the surface area and activity;

[0035] Step 2: Pressing and forming: the ground ore mixture is placed in a processing barrel 42 located on the workpiece frame 2, and the processing barrel 42 is driven by the driving rod 3 to rotate intermittently, and then the punch head 25 is used for punching. The purpose of pressing is to generate various forces between the magnetic material particles and form the desired shape, and the formed magnetic powder is pushed out of the processing barrel 42 by the push plate 38;

[0036] Step 3: Sintering: The pressed magnetic powder needs to be sintered. This step is usually carried out at high temperature to enhance the bonding force between the magnetic powder particles, form a dense structure, and obtain the required mechanical and magnetic properties.

[0037] The bottom of the I-shaped frame 2 is fixedly connected with a support frame 1, a driving rod 3 is rotatably mounted on the I-shaped frame 2, a conveying assembly 4 is arranged on the driving rod 3, a feeding bin 6 is arranged on one side of the top of the I-shaped frame 2, and a control assembly 5 is arranged on one side of the I-shaped frame 2;

[0038] The control assembly 5 is an important part of the whole mechanical system. It is cleverly designed and multifunctional. It is mainly composed of a mounting frame 51, a vertical rod 52, a cam 54, a linkage rod 55, a V-shaped frame 56 and a striking piece. Each part has its own unique function and is closely connected with each other.

[0039] First, the mounting frame 51 is the basis of the control assembly 5. It is fixedly mounted on the front end of the support frame 1 to provide stable support for the entire assembly. The front end of the mounting frame 51 is connected to the vertical rod 52 by rotation, which means that the vertical rod 52 can rotate freely on the mounting frame 51, which provides the possibility for subsequent mechanical actions.

[0040] The outer wall of the vertical rod 52 is fixedly connected with a cam 54, which is a key part of the control assembly 5. The special shape of the cam 54 makes its surface constantly contact with the connecting rod 55 and push it to move when the vertical rod 52 rotates. This design can convert the rotational motion of the vertical rod 52 into the linear motion of the connecting rod 55, thereby realizing the transmission and conversion of mechanical energy.

[0041] The other end of the linkage rod 55 is connected to the V-shaped frame 56 by rotation, and the V-shaped frame 56 is sleeved on the driving rod 3. In this way, when the linkage rod 55 moves, the V-shaped frame 56 will slide on the driving rod 3. This structural design cleverly realizes the linkage between the driving rod 3 and the control component 5, so that the entire mechanical system can work in coordination.

[0042] Second slide grooves 57 are provided inside the two sides of the V-shaped frame 56, which are designed for installing a knocking piece. The knocking piece includes a slide column 58 slidably installed in the second slide groove 57. Both ends of the slide column 58 penetrate the V-shaped frame 56 and are fixedly connected with a knocking block 59. In this way, when the slide column 58 moves in the second slide groove 57, the knocking block 59 will also move accordingly, thereby realizing the knocking action on the target object.

[0043] The limiting blocks 510 are fixedly connected to the outer walls of the sliding column 58 on both sides. The outer ends of the limiting blocks 510 are provided with third springs 511, and the third springs 511 are sleeved on the sliding column 58. This design enables the sliding column 58 to move in the second sliding groove 57 when subjected to external force, and automatically return to its original position through the elastic force of the third spring 511 after the external force disappears. This automatic recovery function is very important in the mechanical system, and it can ensure the continuity and stability of the mechanical action.

[0044] In the embodiment of the present invention, when the wheel disc 32 starts to rotate slowly, it cooperates with the second transmission member 53 to make the vertical rod 52 rotate synchronously. This is not just a simple rotation action, it triggers a series of precise operations. The rotation of the vertical rod 52 drives the rotation of the cam 54, and the cam 54 cooperates closely with the linkage rod 55, so that the V-shaped frame 56 starts its reciprocating swinging motion on the driving rod 3. This series of actions may seem complicated, but in fact it is to achieve a clear purpose: to accurately and efficiently process the magnetic powder in the processing barrel 42:

[0045] When the V-shaped frame 56 drives the knocking block 59 to knock the left side of the processing barrel 42, the main purpose is to achieve uniform distribution and loosening of the magnetic powder. The knocking action causes the powder to be continuously impacted and collided in the barrel, which not only promotes the looseness between the powder particles, but also avoids the occurrence of particle agglomeration or accumulation. This processing method ensures that the subsequent processing process is more uniform and efficient, thereby improving production efficiency and product quality.

[0046] When the knocking block 59 turns to knock the right side of the processing barrel 42, its purpose is to help the magnetic raw material block to be smoothly pushed out of the processing barrel. This knocking action can effectively prevent the raw material block from sticking or getting stuck during the pushing process, thereby ensuring the continuity and stability of the production process.

[0047] Finally, when the knocking block 59 knocks the front end of the processing barrel 42, its function is to help the magnetic powder raw material better fill the processing barrel during the stamping process. By knocking, the shape and density of the magnetic powder block can be adjusted to make it more in line with production requirements, thereby improving the density and uniformity of the product;

[0048] In modern mechanical processing technology, the knocking operation of the knocking block 59 on the processing barrel 42 is a common and important step. In order to ensure the smooth progress of this process and reduce the possible impact and vibration, it is usually necessary to cooperate with the sliding column 58, the limit block 510 and the third spring 511 to perform knocking buffering. This combined design not only improves the processing efficiency, but also significantly enhances the stability and durability of the mechanical equipment.

[0049] During the knocking process, the slide column 58 plays a key role. They are precisely installed between the knocking block 59 and the processing barrel 42. As a medium between the two, the slide column 58 can effectively transmit and control the knocking force. The slide column 58 is usually made of high-strength material, such as stainless steel or alloy steel, to ensure that it is not easily deformed or damaged when subjected to repeated knocking force.

[0050] The stop block 510 is another important component. Its main function is to limit the range of motion of the striking block 59 to prevent it from excessively hitting the processing barrel 42 and causing damage. The stop block 510 is usually made of wear-resistant materials, such as engineering plastics or special alloys, to withstand long-term friction and impact.

[0051] The third spring 511 is the most elastic part of the entire buffer system. It is cleverly installed between the sliding column 58 and the limit block 510. It absorbs and releases energy to buffer the knocking force. When the knocking block 59 hits the processing barrel 42, the third spring 511 will deform and convert part of the impact energy into elastic potential energy for storage. After the impact, the spring will gradually return to its original state and slowly release the stored energy, thereby reducing the vibration and impact of the mechanical system.

[0052] By skillfully combining the slide column 58, the stop block 510 and the third spring 511, the entire knock buffer system can effectively reduce the impact and vibration during the processing, improve the processing accuracy and stability, and at the same time, this design can also extend the service life of the mechanical equipment, reduce the frequency of maintenance and replacement, and thus reduce the production cost.

[0053] In short, in the process of the knocking block 59 knocking the processing barrel 42, the sliding column 58, the limit block 510 and the third spring 511 are used for knocking buffering, which can not only improve the processing efficiency and quality, but also enhance the stability and durability of the mechanical equipment.

[0054] In general, this series of precise mechanical movements not only demonstrates the high development of modern mechanical technology, but also ensures the high efficiency, stability and high quality of magnetic powder processing through the careful design and processing of every detail, which not only improves production efficiency, but also brings us more high-quality products.

[0055] Embodiment 2: Combination Figure 2 , Figure 6As shown, on the basis of the first embodiment, the motor 31 is fixedly installed at the bottom of the support frame 1, and the output end of the motor 31 is closely connected with the wheel 32 to ensure the stable transmission of power. The wheel 32 is not just a simple transmission component, it is connected with the vertical rod 52 through the second transmission member 53 to form a precise transmission system.

[0056] It is worth mentioning that a toggle pin 33 is fixedly connected to one side of the wheel disc 32, so that when the wheel disc rotates, the toggle pin 33 can move according to a predetermined trajectory. A disc 35 is provided on one side of the toggle pin 33, which is firmly mounted on the driving rod 3. Such a design enables the driving rod 3 to achieve the conversion between rotation and linear motion through the interaction between the toggle pin 33 and the disc 35 under the drive of the motor.

[0057] A disc 35 is also fixed to the top of the driving rod 3, which is an important structural feature. A first protrusion 36 is fixedly connected to the bottom of the disc 35 at a position deviating from the center of the circle, which provides a sliding track for the slide bar 37. The slide bar 37 is cleverly designed to be able to slide on the work frame 2. A push plate 38 is fixedly connected to its bottom end, and a second protrusion 39 is fixedly connected to the top. In this way, when the driving rod 3 rotates, the slide bar 37 can move up and down on the work frame 2 through the sliding cooperation of the first protrusion 36 and the second protrusion 39.

[0058] In addition, the outer wall of the slide rod 37 is also sleeved with a first spring 310, which is a carefully designed component that can provide necessary elastic force and buffering when the slide rod 37 moves to ensure stable operation of the system. The presence of the first spring 310 not only enhances the reliability of the system, but also optimizes the friction and wear between mechanical components to a certain extent.

[0059] In the embodiment of the present invention, the wheel disc 32 is driven to rotate synchronously by the rotation force generated by starting the motor 31. The design of the wheel disc 32 is ingenious in that it cooperates with the toggle pin 33 and the intermittent disc 34 to make the driving rod 3 rotate intermittently. This intermittent motion mode plays an important role in many mechanical systems, and it can achieve precise control and adjustment.

[0060] The rotation of the driving rod 3 further drives the rotation of the disc 35 and the first protrusion 36. In this process, when the first protrusion 36 contacts the second protrusion 39, a key action will occur in the whole system: the sliding rod 37 and the push plate 38 will move downward. This action is achieved thanks to the interaction between the first protrusion 36 and the second protrusion 39. The contact between them generates a downward force, thereby promoting the movement of the sliding rod 37 and the push plate 38.

[0061] When the slide bar 37 and the push plate 38 move downward, they compress the first spring 310. The spring plays an important role here. It not only provides the necessary elasticity, but also ensures that the push plate 38 can smoothly push out the magnetic powder pressed and formed in the rotating disk 41. The compression of the first spring 310 provides sufficient thrust for the push plate 38, so that it can overcome possible resistance and ensure the smooth completion of the pushing action.

[0062] Finally, when the push plate 38 pushes out the magnetic powder compacted in the turntable 41, the first protrusion 36 rotates until it no longer contacts the second protrusion 39. Under the elastic force of the first spring 310, the second protrusion 39 and the push plate 38 are reset, and the entire system completes a complete working cycle.

[0063] Example 3: Combination Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, on the basis of the second embodiment, the conveying assembly 4 is an indispensable part of the whole set of equipment, which is cleverly designed and fully functional. The core part of the assembly is a turntable 41 fixedly mounted on the driving rod 3. This turntable 41 is not only stable, but also can efficiently drive the entire processing process through a carefully designed structure. Four groups of processing barrels 42 are fixedly connected to the turntable 41. The four groups of processing barrels 42 are arranged in a circular array, making the processing process more uniform and continuous.

[0064] The bottom of each processing barrel 42 is equipped with a bottom cover 43, which not only plays a sealing role, but also bears the important functions of support and adjustment. At the bottom of the left bottom cover 43, there is a support plate 44, which is fixedly mounted on the workpiece frame 2 to provide a stable support for the entire processing barrel 42. The right end of the support plate 44 is provided with a guide member and an adjustment member. These two parts work together to enable the bottom cover 43 to be accurately adjusted and guided.

[0065] The adjusting member includes a rotating plate 410 fixedly connected to the inner side end of the bottom cover 43, the rotating plate 410 is connected to a connecting plate 49 via a rotating wheel, one end of the connecting plate 49 is fixedly connected to the bottom of the turntable 41, such a design enables the bottom cover 43 to be adjusted accordingly through the linkage between the connecting plate 49 and the rotating plate 410 when the turntable 41 rotates, a fixing rod 411 is also fixedly connected to the inner side end of the rotating plate 410, the other end of the fixing rod 411 is sleeved with a ball 412, the ball 412 is slidably mounted in the guide groove 48, and the precise adjustment of the bottom cover 43 is achieved by the sliding of the ball 412 in the guide groove 48, the outer wall of the fixing rod 411 is also sleeved with a second spring 413, which plays a role of buffering and stabilization.

[0066] The guide member includes a fixed column 46 fixedly mounted on the support plate 44, and the fixed column 46 is sleeved on the positioning column 47. The outer end of the positioning column 47 is provided with a guide groove 48. The design of the guide groove 48 is very unique. It includes a transverse groove 481 and a convex groove 482. The convex groove 482 is located at the rightmost side of the positioning column 47. When the ball 412 slides in the guide groove 48, it will first move along the transverse groove 481, and then when adjustment is needed, it will slide into the convex groove 482 for precise positioning.

[0067] In the embodiment of the present invention, when the driving rod 3 rotates, it has the ability to drive the turntable 41, the processing barrel 42 and the bottom cover 43 to rotate synchronously. This synchronous rotation design allows the entire processing process to proceed smoothly. When the processing barrel 42 on the turntable 41 is located at the leftmost side, the magnetic raw material in the feed bin 6 begins to enter the turntable 41. At this time, the ball 412 is just located in the transverse groove 481, and together with the fixed rod 411, the rotating plate 410 and the bottom cover 43, it forms a horizontal structure. This structure enables the bottom cover 43 to seal the bottom of the processing barrel 42, effectively preventing the leakage of raw materials during the processing process.

[0068] Subsequently, the driving rod 3 continues to drive the conveying assembly 4 to rotate 90 degrees. During this process, the bottom cover 43 moves to the top of the mounting frame 51. At this time, the punching head 25 starts to work and punches the magnetic raw material in the processing barrel 42. After the punching process is completed, the driving rod 3 starts again to drive the conveying assembly 4 to rotate 90 degrees. This time, the processing barrel 42 after the punching is moved to the far right.

[0069] In this process, the ball 412 moves from the transverse groove 481 into the ball 412 under the elastic force of the second spring 413. This movement process drives the rotating plate 410 and the bottom cover 43 to rotate on the connecting plate 49, so that the bottom cover 43 is just in an open state. At this time, the push plate 38 will quickly push the pressed magnetic raw material out of the processing barrel 42, thereby completing the material withdrawal process of the magnetic raw material.

[0070] As the conveying assembly 4 continues to rotate, the ball 412 begins to move from the convex groove 482 to the transverse groove 481. In this process, the fixing rod 411, the second spring 413, the rotating plate 410, and the connecting plate 49 drive the bottom cover 43 to rotate again, and the bottom of the turntable 41 is sealed. This design not only ensures the continuity of the processing process, but also effectively prevents the leakage of raw materials, reflecting the exquisiteness and practicality of the process design.

[0071] On the whole, the entire processing flow is very cleverly designed, with each link working closely and orderly. From the entry of raw materials, to the stamping process, to the final material return process, each step has been carefully designed and optimized to improve production efficiency and product quality. At the same time, this design also fully considers the convenience and safety of operation, making the entire processing process both efficient and safe.

[0072] Embodiment 4: Combination Figure 7 As shown, on the basis of the third embodiment, a rectangular frame 21 is fixedly connected to the inner end of the work-shaped frame 2. This design not only stabilizes the overall structure, but also provides necessary support for subsequent mechanical actions. A first slide groove 22 is cleverly provided at the inner end of the rectangular frame 21. The existence of the slide groove provides a path for the sliding of the slide rod 23, so that the slide rod 23 can move freely and smoothly in the slide groove.

[0073] The bottom of the slide rod 23 is connected to the bidirectional screw rod 24 by rotation. This connection mode not only ensures the sliding freedom of the slide rod 23, but also enables the bidirectional screw rod 24 to rotate under the drive of the slide rod 23. The bottom end of the bidirectional screw rod 24 passes through the workpiece frame 2 and is provided with a punch head 25. When the bidirectional screw rod 24 rotates, the punch head 25 moves up and down accordingly to realize the punching action. This is one of the key parts in the entire mechanical structure.

[0074] It is worth noting that the outer wall of the bidirectional screw rod 24 is also threadedly connected to a sleeve rod 26. This design enables the sleeve rod 26 to move along its axis under the rotation of the bidirectional screw rod 24, thereby realizing power transmission and coordinated movement. At the same time, the sleeve rod 26 is connected to the vertical rod 52 through the first transmission member 27. This connection makes the entire mechanical structure more coordinated and smooth in movement.

[0075] In the embodiment of the present invention, when the vertical rod 52 starts to rotate, the vertical rod 52 and the first transmission member 27 are matched, and the rotation of the vertical rod 52 drives the rotation of the first transmission member 27. The force of this rotation is transmitted to the sleeve rod 26, and the sleeve rod 26 is closely connected with the bidirectional screw rod 24 through a thread. This design cleverly converts the rotational motion into a linear motion. When the sleeve rod 26 is rotated by the driving force of the first transmission member 27, the bidirectional screw rod 24 also starts to rotate. At the same time, a precise linkage relationship is formed between the sliding rod 23 and the bidirectional screw rod 24. The rotation of the bidirectional screw rod 24 drives the sliding rod 23 to move along a predetermined track. In this whole machine, In the process of mechanical linkage, the punch head 25 becomes the final executor. It is tightly connected to the end of the sliding rod 23 and moves with the movement of the sliding rod 23. When the sliding rod 23 moves downward, the punch head 25 also punches downward, and the magnetic raw material in the turntable 41 is accurately and powerfully punched. At the same time, the support plate 44 supports the bottom cover 43 at the bottom of the processing barrel 42 to assist the punching work. This punching process is very important for the processing of magnetic raw materials. Through punching, the raw materials can be molded into the required shape and size to meet the requirements of subsequent processes. At the same time, the punching process can also enhance the density and magnetism of the raw materials and improve their overall performance.

[0076] In general, the rotation of the vertical rod 52 triggers a series of mechanical linkages, which ultimately achieves the stamping process of the magnetic raw material. In this process, each component plays an indispensable role and together constitutes this precise and efficient mechanical system.

[0077] Embodiment 5: Combination Fig.10 As shown, based on the fourth embodiment, the support frame 1 is located at the core position of the entire mechanical device. It not only provides stable support, but also serves as a connection point for multiple movable parts. At the top right side of the support frame 1, the support rod 71 is fixed by a precise fixed connection. The support rod 71 carries the moving frame 72, and the moving frame 72 can slide freely left and right on the support rod 71.

[0078] The design of the mobile frame 72 cleverly combines the sliding and connecting functions. The front and rear sliding connections on the top are connected to the plug rod 76, and the top of the plug rod 76 is fixedly installed with the material receiving box 7. The position of the material receiving box 7 is carefully arranged below the processing barrel 42 on the right side to facilitate receiving the processed materials in the processing barrel 42. This design not only improves the work efficiency, but also ensures the continuity and stability of material transmission.

[0079] The inner end of the movable frame 72 is provided with a toggle convex plate 73, which is a part of the driving rod 3. When the driving rod 3 is working, the toggle convex plate 73 will rotate accordingly, thereby driving the movable frame 72 to slide on the supporting rod 71. This design enables the mechanical device to achieve automation and precise control during operation.

[0080] At the outer end of the moving frame 72, a moving rod 74 is fixedly connected. The moving rod 74 is slidably installed on the work-shaped frame 2, so that the moving frame 72 is more stable during the sliding process. At the same time, a fourth spring 75 is also mounted on the moving rod 74. The existence of the fourth spring 75 provides a buffer and reset function for the movement of the moving frame 72, ensuring the stability and durability of the mechanical device after long-term work.

[0081] In the embodiment of the present invention, in industrial production, the stamping process of magnetic material powder often faces a thorny problem: after the stamping is completed, the magnetic material powder will inevitably remain on the surface of the stamped part. These residual powders not only affect the appearance of the product, but may also have a negative impact on the performance of the product. In order to solve this problem, engineers have designed an efficient screening device to ensure that the magnetic material powder can be completely removed after the stamping is completed. The driving rod 3 realizes precise control of the screening process by linkage with the toggle convex plate 73. When the driving rod 3 starts to rotate, the toggle convex plate 73 will rotate synchronously. This design cleverly utilizes the principle of mechanical transmission to ensure the stability and continuity of the screening process.

[0082] Driven by the cam 73, the moving frame 72 starts to move back and forth on the support rod 71 in cooperation with the fourth spring 75. This action seems simple, but it is actually ingenious. It enables the material receiving box 7 to shake continuously. This shaking is not only powerful but also uniform, ensuring that the magnetic material powder on the material receiving box 7 can fully pass through the sieve holes to achieve effective screening.

[0083] Through this screening process, the magnetic material powder on the receiving box 7 is effectively screened out, and the unqualified powder remaining in the stamping process is removed. In this way, the quality of the stamped magnetic material powder product is greatly improved, not only the appearance is more beautiful, but also the performance is more stable and reliable.

[0084] It is worth noting that the design of this screening device fully considers the balance between production efficiency and screening effect. The parameters such as the rotation speed of the driving rod 3, the shape and size of the toggle convex plate 73, and the moving range of the moving frame 72 have been carefully designed and optimized to ensure the high efficiency and accuracy of the screening process.

[0085] In addition, this screening device also has a certain versatility and can adapt to the screening needs of magnetic material powders of different specifications and types. By adjusting the rotation speed of the driving rod 3 and the size of the sieve hole, it can easily achieve the screening of powders of different particle sizes, thereby meeting the needs of different production scenarios.

[0086] In summary, this screening device achieves efficient screening of magnetic material powder remaining on its surface after stamping through ingenious mechanical transmission design and reasonable parameter optimization. It not only improves product quality, but also improves production efficiency, bringing revolutionary changes to the stamping production of magnetic material powder.

[0087] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
