Description

Technical Field

[0001] The utility model belongs to the field of rare earth permanent magnet magnetic powder processing, and particularly relates to an automatic magnetic block material taking device with a turning function and a magnetic field forming press having the same. Background Art

[0002] Sintered NdFeB is the most powerful permanent magnet available today. It not only boasts high remanence, high coercivity, high magnetic energy product, and a high cost-effectiveness, but is also easily processed into various sizes, making it particularly suitable for high-performance, miniaturized, and lightweight electronic products. In recent years, the rapid development of high-tech industries, particularly the information industry, has placed increasingly higher demands on the performance of NdFeB. The production process for sintered NdFeB generally follows a process flow that includes raw material testing, formulation, belt spinning, hydrogen crushing, coarse mixing, pulverizing, fine mixing, molding, and sintering.

[0003] An example of the prior art, such as the applicant's prior patent application CN219900248U, discloses a fully electrically driven four-column guided magnetic field pressure forming press, comprising a frame with a working chamber; a forming fixed die plate, connected to the frame by at least four fixed die guide pillars and located in the middle of the working chamber, and provided with a magnetic powder cavity; an upper movable die plate, connected to the frame by at least four movable die guide pillars and located above the forming fixed die plate; a lower movable die plate, connected to the frame by movable die guide pillars and located below the forming fixed die plate; an upper electric cylinder assembly, mounted on the top of the frame and acting on the upper movable die plate; a lower electric cylinder assembly, mounted on the lower end of the frame and acting on the lower movable die plate; self-lubricating sleeves are provided between the upper and lower movable die plates and the movable die guide pillars.

[0004] Similar to the aforementioned patented products, they have certain drawbacks. For example, the automatic forming presses currently on the market require manual clamping after the magnetic block product is formed, which is very cumbersome and cannot guarantee the stability of the clamping. In particular, when the product is large and heavy, two or more people are required to complete the removal work. After removal, the magnetic block product must be flipped 90 degrees to facilitate the subsequent plastic bagging and vacuum sealing process. This requires the collaboration of three people, which is labor-intensive, easily damages the product, and is costly. Summary of the Invention

[0005] In order to overcome the above-mentioned deficiencies in the prior art, the utility model provides an automatic magnetic block material taking device with a flipping function and a magnetic field forming press having the same.

[0011] The support plate assembly is connected to the first clamping arm and the second clamping arm, and a magnetic block clamping space is formed in the support plate assembly.

[0012] A more preferred structural setting for the above technical solution is that the support plate assembly forms a detachable connection with the first clamping arm and the second clamping arm.

[0013] Regarding the specific structure of the support plate assembly, the support plate assembly includes a fixed support plate and a detachable support plate, and the area of ​​the detachable support plate is larger than the area of ​​the fixed support plate;

[0014] The fixed supporting plate is assembled on the first clamping arm, and the detachable supporting plate is assembled on the second clamping arm.

[0015] Furthermore, the detachable support plate is provided with an assembly groove, and the second clamping arm is at least partially inserted into the assembly groove.

[0016] Regarding the specific structural setting of the driving component, the driving component includes a driving motor, a screw rod acted by the driving motor, a nut seat sleeved on the screw rod and capable of moving along the screw rod, and a linkage bracket connected between the nut seat and the sliding plate and / or the sliding block.

[0017] The utility model also provides a magnetic field forming press, comprising:

[0018] Forming press body;

[0019] A magnet forming die is provided in the forming press body and has a magnet cavity. After magnetic powder is added to the magnet cavity, a magnet product can be formed under the action of the forming press body.

[0020] The molding press body is also provided with the aforementioned automatic magnetic block taking device with a turning function.

[0021] In some preferred embodiments of the present invention, the forming press body is connected to a track base plate via a fixing rod, and the slide rail and the driving assembly are fixed on the track base plate.

[0023] Under the action of the driving device, the movable upper mold core can be molded together with the fixed lower mold core in the mold body to form the magnetic block cavity.

[0024] Furthermore, the lower end of the mold body is connected to a second lifting drive device, so that the mold body can move up and down relative to the magnetic block cavity.

[0025] A preferred setting for the forming press body is that the forming press body includes a press frame, a processing cavity formed in the press frame, and a magnetic coil assembly fixed on the press frame and symmetrically distributed on both sides of the processing cavity; the magnetic block forming mold is located between the magnetic coil assemblies on both sides of the processing cavity, and a protective plate is also provided between the magnetic block forming mold and the magnetic coil assembly.

[0041] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments are merely a specific description of the present invention, and their purpose is to allow those skilled in the art to better understand the technical solution of the present invention, and should not be regarded as limiting the present invention.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0043] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0044] Example 1

[0045] Reference Figures 1 to 9 , an automatic magnetic block material taking device 1 with a flipping function, comprising:

[0046] A slide rail 14 is provided with a sliding block 11, and a sliding plate 12 is connected to the sliding block 11. Preferably, there are two slide rails 14 and they are symmetrically arranged, and there are an even number of sliding blocks 11 and they are evenly distributed on the slide rail 14. The sliding block 11 is a single integral unit and is connected to each sliding block 11, so that the force can be evenly distributed, and the sliding blocks 11 are more stable and quiet during the sliding process;

[0047] The driving assembly 2 acts on the sliding plate 12 and / or the sliding block 11 to enable the sliding plate 12 and the sliding block 11 to reciprocate along the slide rail 14;

[0048] The vertical support plate 13 is connected to the lower end of the sliding plate 12 and mainly serves to connect and support components;

[0049] A rotating cylinder 31 is mounted on the vertical support plate 13 , and a rotating output end of the rotating cylinder 31 is connected to a clamping cylinder 32 , and the clamping cylinder 32 is connected to a first clamping arm 321 and a second clamping arm 322 ;

[0050] The support plate assembly 4 is connected to the first clamping arm 321 and the second clamping arm 322 , and a magnetic block clamping space is formed in the support plate assembly 4 .

[0051] The above content is the basic structural scheme of the utility model, and its working principle is: the driving component 2 is started to make the sliding plate 12 and the sliding block 11 move to the specified position along the slide rail 14 together, and then the rotating cylinder 31 on the vertical support plate 13 is started to adjust the relative position relationship between the first clamping arm 321 and the second clamping arm 322 and the magnetic block product 5, so that the magnetic block product 5 enters the magnetic block clamping space of the support plate component 4 and then the clamping cylinder 32 is started to drive the support plate component 4 to move closer (reduce the magnetic block clamping space) through the first clamping arm 321 and the second clamping arm 322, thereby clamping the magnetic block product 5. Then the driving component 2 is started again, so that the sliding plate 12 and the sliding block 11 (magnetic block product 5) move together along the slide rail 14 to the downstream process position, and the rotating cylinder 31 is started again to flip the support plate component 4, and at the same time realize the flipping of the magnetic block product 5. Finally, the clamping cylinder 32 is started a second time to drive the support plate component 4 to loosen (expand the magnetic block clamping space) through the first clamping arm 321 and the second clamping arm 322 to release the magnetic block product 5 and complete the operation of automatically taking out the magnetic block material.

[0052] It should be noted that a more preferred structural setting of the above technical solution is that the support plate assembly 4 is detachably connected to the first clamping arm 321 and the second clamping arm 322. Therefore, support plate assemblies 4 of different shapes and sizes can be replaced and matched on the first clamping arm 321 and the second clamping arm 322, achieving multi-purpose use of one machine to meet the needs of clamping and using magnetic products 5 of different shapes and sizes.

[0053] In the above, the specific combination scheme of the support plate assembly 4 is: refer to Figures 4 to 6 , the pallet assembly 4 includes a fixed pallet 41 and a detachable pallet 42. During the flipping process, the fixed pallet 41 is located on the side or top of the magnetic product 5, and the detachable pallet 42 is located on the side or bottom of the magnetic product 5, so that the fixed pallet 41 serves as a structural part that provides auxiliary support force, and the detachable pallet 42 serves as a structural part that provides the main support force. In order to achieve an ideal support effect, the area of ​​the detachable pallet 42 is limited to be larger than the area of ​​the fixed pallet 41. It is particularly necessary to set the detachable pallet 42 to a larger size than the magnetic product 5 to provide a more stable and reliable support effect and prevent the magnetic product 5 from falling during clamping and moving. Preferably, the fixed pallet 41 is in the shape of a round cake, and the detachable pallet 42 is in the shape of a rectangle.

[0054] Based on the above support requirements, the fixed support plate 41 generally does not need to be replaced, and is therefore fixedly mounted (e.g., with screws) on the first clamping arm 321, and the detachable support plate 42 is mounted on the second clamping arm 322. The detachable support plate 42 is provided with a mounting groove 421, and the second clamping arm 322 is at least partially inserted into the mounting groove 421, which facilitates quick assembly and disassembly, and the structure is sufficiently stable after insertion.

[0055] Preferably, the first clamping arm 321 is in the shape of a single flat plate with a threaded hole 3211 provided on it for the screw to pass through; the cross-section of the second clamping arm 322 is in the shape of a "convex" character, and a limiting and anti-slip effect is formed through the stepped structure on both sides and the assembly groove 421.

[0056] There are many different structural solutions for the drive assembly 2. The preferred solution in this utility model is as follows: Figures 3 and 4 The drive assembly 2 includes a drive motor 21, a screw rod 22 driven by the drive motor 21, a nut seat 23 sleeved on the screw rod 22 and capable of moving along the screw rod 22, and a linkage bracket 24 connected between the nut seat 23 and the sliding plate 12 and / or the sliding block 11. Preferably, an escape groove is formed on the track base plate 61 to allow the linkage bracket 24 to cross from the upper side of the track base plate 61 to the lower side of the track base plate 61, thereby achieving a transitional connection between the nut seat 23 and the sliding plate 12.

[0057] Example 2

[0058] Reference Figures 1 and 2 The utility model also provides a magnetic field forming press, including: a forming press body 6; a magnetic block forming mold 7, which is arranged in the forming press body 6 and has a magnetic block cavity 71. After magnetic powder is added to the magnetic block cavity 71, a magnetic block product 5 can be formed under the action of the forming press body 6; the forming press body 6 is also provided with the automatic magnetic block material taking device 1 with a flipping function as described above.

[0059] Among them, the magnetic block forming mold 7 is replaceable, so different magnetic block forming molds 7 can have magnetic block cavities 71 of different shapes to form magnetic block products 5 of different sizes and shapes. Different magnetic block products 5 need to cooperate with different support plate assemblies 4 when clamping and unloading to ensure the stability of clamping.

[0060] In order to realize the installation of the automatic magnetic block material removal device 1, in this embodiment, the molding press body 6 is connected to the track base plate 61 through the fixing rod 63, and the slide rail 14 and the drive assembly 2 are fixed to the track base plate 61. Furthermore, the track base plate 61 is also connected to the molding press body 6 through the reinforcement bracket 62. The dual connection structure of the fixing rod 63 and the reinforcement bracket 62 provides better support and ensures structural stability.

[0061] The specific configuration of the forming press body 6 is as follows: the forming press body 6 includes a press frame 64, a processing cavity 65 formed in the press frame 64, and a magnetic coil assembly 66 fixed to the press frame 64 and symmetrically distributed on both sides of the processing cavity 65. The magnetic block forming mold 7 is located between the magnetic coil assemblies 66 on both sides of the processing cavity 65, and a protective plate 67 is provided between the magnetic block forming mold 7 and the magnetic coil assembly 66. The protective plate 67 can serve as an isolation and protection function. The working principle of the forming press body 6 is almost the same as that of the prior art, so it will not be described in detail in this case.

[0062] Example 3

[0063] Reference Figures 1 and 2 , reference Figures 7 to 9 Based on the structure of Example 2, the preferred setting of the magnetic block forming mold 7 is that the magnetic block forming mold 7 includes a mold body 72, a fixed lower mold core 73 located at the lower end of the mold body 72, a movable upper mold core 74 located above the mold body 72, and a first lifting drive device 75 for driving the movable upper mold core 74; under the action of the drive device, the movable upper mold core 74 can be molded with the fixed lower mold core 73 in the mold body 72 to form the magnetic block cavity 71.

[0064] Furthermore, the lower end of the mold body 72 is connected to a second lifting drive device 76, so that the mold body 72 can move up and down relative to the magnetic cavity 71. During use, when the mold body 72 is driven upward by the second lifting drive device 76, it corresponds to the mold closing and molding stage; when the mold body 72 is driven downward by the second lifting drive device 76, it corresponds to the mold separation and material removal stage. That is, after the mold body 72 is lowered, the magnetic block product 5 that has been formed in the magnetic cavity 71 can be at least partially exposed outside the mold body 72, playing a avoidance role and providing operating space, so that the support plate assembly 4 can easily pick up the magnetic block product 5.

[0065] It is worth noting that other technical solutions of the present invention belong to the existing technology and are therefore not described in detail.

[0066] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the concept of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
