Description

Technical Field

[0001] This invention relates to the field of magnetic powder forming technology, specifically to a magnetic field press and method for processing magnetic materials. Background Technology

[0002] The magnetic field press, also known as the magnetic field forming press, is a key piece of equipment for manufacturing high-performance permanent magnets (such as neodymium iron boron and ferrite). The core function of the magnetic field press is to apply a strong magnetic field during the powder pressing process, so that the magnetic powder particles are arranged in an orderly manner (orientation) in a specific direction inside the compact, thereby giving the final sintered magnet excellent magnetic properties.

[0003] Publication No. CN119346869A discloses a sealed magnetic field press, including a material storage device, a powder loading box, a compact conveying device, a press frame, an upper pressure head assembly, a lower pressure head assembly, a mold device, and orientation magnetic poles. The upper pressure head assembly, mold device, lower pressure head assembly, and orientation magnetic poles are arranged inside the press frame. The mold device, together with the upper pressure head assembly, lower pressure head assembly, and orientation magnetic poles, bidirectionally presses the alloy powder in the mold cavity under magnetic field orientation, pressing the alloy powder into a compact. Then, the upper pressure head assembly and lower pressure head assembly move in the same direction to eject the compact from the mold cavity. One side of the press frame is connected to the powder loading box, and the other side is connected to the compact conveying device. An interface is provided at the connection between the press frame and the compact conveying device, and a compact door is provided at the interface. After the compact door is opened, the compact can pass through the interface and be conveyed into the compact conveying device. This sealed magnetic field press operates under a protective atmosphere.

[0004] Although the aforementioned applications and prior art can isolate the alloy powder and the compact from the atmosphere during the magnetic field forming process, when the alloy powder is filled, the alloy powder will "bridge" inside the filling shoe, resulting in the accumulation of alloy powder inside the filling shoe. This prevents the alloy powder from completely filling the mold. Furthermore, when using vibration to prevent the accumulation of alloy powder inside, the vibration will cause the fine alloy powder and coarse alloy powder inside the filling shoe to separate, which will affect the forming of the alloy powder. Moreover, when the alloy powder inside the filling shoe is vibrated, static electricity is generated between the alloy powders through friction. The alloy powder with static electricity will affect the subsequent orientation, resulting in differences in the magnetic properties of the formed product. Therefore, this invention proposes a magnetic field press equipment and method for processing magnetic materials. Summary of the Invention

[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a magnetic field press and method for processing magnetic materials. It offers advantages such as preventing accumulation, avoiding delamination, and eliminating static electricity. This solves the problems of the aforementioned applications and existing technologies, where alloy powder "bridging" occurs inside the filling shoe during filling, leading to powder accumulation and preventing complete filling of the mold. Furthermore, when using vibration to prevent powder accumulation, the vibration causes delamination between fine and coarse alloy powder inside the filling shoe, affecting powder molding. Additionally, vibration of the alloy powder inside the filling shoe generates static electricity through friction, which can affect subsequent orientation, resulting in differences in the magnetic properties of the molded product.

An anti-bridging assembly is disposed on the surface of the replenishment box to prevent powder from bridging and accumulating inside the replenishment box. The anti-bridging assembly includes several fixed cylinders fixedly connected to the surface of the replenishment box. Each of the fixed cylinders has a sliding disk slidably connected inside. A vibration spring is fixedly connected between the sliding disk and the inner wall of the fixed cylinder.

The static electricity elimination component is disposed on the surface of the replenishment box to eliminate static electricity generated by the powder inside the replenishment box during vibration, thereby preventing static electricity from affecting powder molding.

[0007] Furthermore, a protective shell is fixedly connected to the surface of the replenishment box, an extension rod is fixedly connected to the end of the sliding disc away from the vibration spring, and a striking plate is fixedly connected to the end of the extension rod away from the sliding disc.

[0008] Furthermore, the protective frame assembly also includes a fixed plate fixedly connected inside the protective shell. An air inlet pipe is fixedly connected to the surface of the fixed plate, and a first rotating rod is rotatably connected inside the fixed plate. A cam is fixedly connected to the surface of the first rotating rod outside the fixed plate.

[0009] Furthermore, the anti-sinking component includes a mounting plate fixedly connected to the top of the replenishment box and a conveying cylinder fixedly connected inside the replenishment box. The mounting plate and the fixed plate are connected through a first connecting pipe. An auger rod is rotatably connected inside the mounting plate. The surface of the conveying cylinder is provided with several feed slots and several discharge slots.

[0010] Furthermore, the anti-sinking component also includes two second rotating rods rotatably connected inside the replenishment box. Several arc-shaped strips are fixedly connected to the surface of each of the two second rotating rods, and the two second rotating rods are transmitted to the auger rod through a transmission mechanism.

[0011] Furthermore, the power dissipation component includes a nitrogen box fixedly connected inside the protective shell and a gas storage box fixedly connected inside the protective shell. An air extraction cylinder is fixedly connected inside the nitrogen box, and the gas storage box and the air extraction cylinder are connected through a T-shaped pipe. An air jet box is fixedly connected to the inner wall of the replenishment box, and the air jet box and the gas storage box are connected through a vent pipe. A pressure relief valve is provided on the surface of the vent pipe.

[0012] Furthermore, the current dissipation assembly also includes a limiting plate fixedly connected inside the protective shell. The limiting plate and the mounting plate are connected through a second connecting pipe. A third rotating rod is rotatably connected inside the limiting plate. One end of the third rotating rod is fixedly connected to a driving plate, and one end of the driving plate is fixedly connected to a fixing rod.

[0013] Furthermore, the anti-static assembly also includes a soil plate slidably connected inside the protective shell. The surface of the soil plate is provided with a drive groove, and a suction cup is fixedly connected to the bottom of the soil plate. The suction cup is slidably connected inside the air extraction cylinder. Several rotating plates are fixedly connected to the surfaces of the third rotating rod, the auger rod, and the first rotating rod.

[0015] The present invention also provides a magnetic field press method for processing magnetic materials, which specifically includes the following steps: Step 1: Connect the external air source to the anti-bridging component. When bridging occurs inside the replenishment box, the anti-bridging component will knock and vibrate the replenishment box to prevent the powder inside from bridging and accumulating. Step 2: When the anti-sinking component is in operation, the anti-sinking component is driven synchronously, so that the anti-sinking component conveys the fine powder at the bottom of the inside of the feeding box and remixes it with the coarse powder at the top of the inside, so as to avoid powder stratification. Step 3: When the anti-sinking component is in operation, the static elimination component is driven synchronously to eliminate the static electricity inside the feeding box, thereby preventing static electricity from affecting powder molding. Step 4: When the replenishment box moves to the top of the processing tank, the powder inside the replenishment box enters the interior of the processing tank to fill it; Step 5: When the replenishment box returns to its initial state, the stamping cylinder drives the stamping plate through the telescopic rod to stamp and shape the powder inside the processing tank.

[0016] (III) Beneficial Effects Compared with the prior art, the present invention provides a magnetic field press and method for processing magnetic materials, which has the following beneficial effects: 1. The magnetic field press equipment and method for processing magnetic materials, through the use of the anti-frame assembly, connects the external air source to the air inlet pipe. The air source enters the fixed plate through the air inlet pipe, causing the rotating plate to drive the cam to rotate through the first rotating rod. When the cam contacts the striking plate, the striking plate drives the sliding plate to move through the extension rod, causing the sliding plate to drive the vibration spring to stretch. When the cam is not in contact with the striking plate, the vibration spring quickly returns to its initial state and generates vibration, which is then transmitted to the inside of the replenishment box through the fixed cylinder, so that the powder inside the replenishment box no longer accumulates due to vibration, thereby achieving the effect of preventing accumulation.

[0017] 2. The magnetic field press equipment and method for processing magnetic materials, through the combined use of the anti-frame assembly and the anti-sinking assembly, allows the air source inside the fixed plate to enter the interior of the mounting plate through the first connecting pipe, causing the rotating plate to drive the auger rod to rotate. The fine powder at the bottom of the feeding box enters the interior of the conveying cylinder through the feeding chute, and then moves out of the discharge chute through the rotation of the auger rod. At the same time, the auger rod drives the second rotating rod to rotate through the transmission mechanism, causing the second rotating rod to stir the powder through the arc strip, so that the coarse powder and fine powder are fully mixed, thereby achieving the effect of avoiding stratification.

[0018] 3. The magnetic field press equipment and method for processing magnetic materials, through the combined use of the anti-sinking component and the static elimination component, the air source inside the mounting plate enters the limiting plate through the second connecting pipe, causing the rotating plate to drive the drive plate and the fixed rod to rotate through the third rotating rod. In turn, the fixed rod drives the soil plate to slide up and down inside the protective shell through the drive groove. The soil plate continuously delivers nitrogen from the nitrogen box to the inside of the gas storage box through the air extraction cylinder and the T-shaped pipe. When the threshold of the pressure relief valve is reached, the nitrogen inside the gas storage box enters the inside of the air jet box through the vent pipe and is ejected, so that the ejected nitrogen eliminates static electricity, thereby achieving the effect of eliminating static electricity.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] The devices or elements referred to in the embodiments of this application or implied herein must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as limiting the embodiments of this application. In the description of the embodiments of this application, "a plurality of" means two or more, unless otherwise precisely specified.

[0024] For a specific implementation example, please refer to Implementation Example 1. Figures 1 to 2 A magnetic field press for processing magnetic materials includes: a processing box 1 and a stamping plate 162 disposed inside the processing box 1. A processing groove 15 is opened inside the processing box 1. A stamping cylinder 16 is fixedly connected to the top of the processing box 1. A telescopic rod 161 is differentially connected to the bottom of the stamping cylinder 16. The bottom of the telescopic rod 161 is fixedly connected to the top of the stamping plate 162. A replenishment box 17 is slidably connected inside the processing box 1. A protective shell 172 is fixedly connected to the surface of the replenishment box 17. A recycling box 11 is slidably connected to one side of the processing box 1. A recycling groove 12 is opened inside the processing box 1. A feeding cylinder 13 is fixedly connected inside the processing box 1. Four guide rods 14 for the stamping plate 162 to slide are fixedly connected inside the processing box 1. Several feeding ports 171 are fixedly connected to the top of the replenishment box 17. A baffle plate 173 is fixedly connected to the top of the protective shell 172. Anti-bridging assembly 2 is disposed on the surface of the replenishment box 17 to prevent powder from bridging and accumulating inside the replenishment box 17. The anti-bridging assembly 2 includes several fixed cylinders 22 fixedly connected to the surface of the replenishment box 17. Each of the fixed cylinders 22 has a sliding disk 221 slidably connected inside. A vibration spring 222 is fixedly connected between the sliding disk 221 and the inner wall of the fixed cylinder 22. The anti-sinking component 3 is installed inside the replenishment box 17 to prevent fine powder inside the replenishment box 17 from settling at the bottom when the anti-frame component 2 vibrates against it. The static electricity elimination component 4 is disposed on the surface of the feeding box 17 and is used to eliminate the static electricity generated by the powder inside the feeding box 17 during vibration, so as to avoid the static electricity affecting the powder forming. It should be noted that when the replenishment box 17 moves to the bottom of the feed cylinder 13, the powder inside the feed cylinder 13 can replenish the powder inside the replenishment box 17. An electromagnet is provided on the surface of the processing tank 15, and the powder is oriented by the electromagnet. A punching head is fixedly connected to the bottom of the punching plate 162, and the blocking plate 173 can block the opening at the bottom of the feed cylinder 13. When the powder needs to be stamped, the feeding box 17 is moved into the processing tank 15, so that the powder inside the feeding box 17 enters the processing tank 15. Then the feeding box 17 is returned to the initial state, and the stamping cylinder 16 is started. The stamping cylinder 16 drives the stamping plate 162 to descend through the telescopic rod 161, so that the stamping head at the bottom of the stamping plate 162 stamps the powder inside the processing tank 15. After the stamping is completed, the stamping plate 162 is returned to the initial state, and then the finished product inside the processing tank 15 is ejected. As the feeding box 17 is fed, the feeding box 17 pushes the formed finished product, thus forming a reciprocating motion. For a specific embodiment two, please refer to Figures 1 to 8 Based on the magnetic field press equipment for processing magnetic materials provided in Specific Embodiment 1, this embodiment provides a further technical solution: An extension rod 223 is fixedly connected to one end of the sliding disc 221 away from the vibration spring 222, and a striking plate 224 is fixedly connected to one end of the extension rod 223 away from the sliding disc 221. The anti-frame assembly 2 also includes a fixed disc 21 fixedly connected inside the protective shell 172. An air inlet pipe 213 is fixedly connected to the surface of the fixed disc 21. A first rotating rod 211 is rotatably connected inside the fixed disc 21. A cam 212 is fixedly connected to the surface of the first rotating rod 211 and located outside the fixed disc 21. It should be noted that the air inlet pipe 213 is retractable, so that when the feed 17 moves, the air inlet pipe 213 can deliver the air source to the interior of the fixed plate 21. To prevent powder from accumulating inside the replenishment box 17 and affecting its entry into the processing tank 15, an external air source is connected to the air inlet pipe 213. The air source enters the fixed plate 21 through the air inlet pipe 213, causing the rotating plate 18 to drive the cam 212 to rotate via the first rotating rod 211. When the cam 212 contacts the striking plate 224, the striking plate 224 drives the sliding plate 221 to move via the extension rod 223, causing the sliding plate 221 to stretch the vibration spring 222. When the cam 212 is no longer in contact with the striking plate 224, the vibration spring 222 quickly returns to its initial state and generates vibration, which is then transmitted to the inside of the replenishment box 17 through the fixed cylinder 22. This prevents the powder inside the replenishment box 17 from accumulating due to vibration, thus allowing the powder inside the replenishment box 17 to smoothly enter the processing tank 15. For a specific embodiment three, please refer to Figures 1 to 11 Based on the magnetic field press equipment for processing magnetic materials provided in Specific Embodiment 2, this embodiment provides a further technical solution: The anti-sinking component 3 includes a mounting plate 31 fixedly connected to the top of the replenishment box 17 and a conveying cylinder 32 fixedly connected inside the replenishment box 17. The mounting plate 31 and the fixed plate 21 are connected through a first connecting pipe 312. An auger rod 311 is rotatably connected inside the mounting plate 31. The surface of the conveying cylinder 32 is provided with several feed grooves 321 and several discharge grooves 322. The anti-sinking component 3 also includes two second rotating rods 33 rotatably connected inside the replenishment box 17. Several arc-shaped strips 331 are fixedly connected to the surface of each of the two second rotating rods 33. The two second rotating rods 33 are driven by the auger rod 311 through a transmission mechanism 332. It should be noted that the height of the mounting plate 31 is the same as the height of the feed port 171. The transmission mechanism 332 includes a drive sprocket fixedly connected to the surface of the auger rod 311 and a driven sprocket fixedly connected to the surface of the second rotating rod 33. The drive sprocket and the driven sprocket are driven by a chain, and the diameter of the drive sprocket is larger than that of the driven sprocket. To prevent the powder inside the feeding box 17 from stratifying during vibration, the air source inside the fixed plate 21 enters the mounting plate 31 through the first connecting pipe 312, causing the rotating plate 18 to drive the auger rod 311 to rotate. The fine powder at the bottom of the feeding box 17 enters the conveying cylinder 32 through the feeding chute 321, and then moves out of the discharge chute 322 through the rotation of the auger rod 311. At the same time, the auger rod 311 drives the second rotating rod 33 to rotate through the transmission mechanism 332, so that the second rotating rod 33 stirs the powder through the arc strip 331, thereby making the coarse powder and fine powder fully mixed, thus preventing the powder from stratifying inside the feeding box 17 and affecting the subsequent powder forming. For a specific implementation example, please refer to Implementation Example 4. Figures 1 to 14 Based on the magnetic field press equipment for processing magnetic materials provided in Specific Embodiment 3, this embodiment provides a further technical solution: The static extinguishing component 4 includes a nitrogen box 41 fixedly connected inside the protective shell 172 and a gas storage box 42 fixedly connected inside the protective shell 172. An air extraction cylinder 411 is fixedly connected inside the nitrogen box 41. The gas storage box 42 and the air extraction cylinder 411 are connected via a T-tube 421. An air jet box 424 is fixedly connected to the inner wall of the replenishment box 17. The air jet box 424 and the gas storage box 42 are connected via a vent pipe 422. A pressure relief valve 423 is provided on the surface of the vent pipe 422. The static extinguishing component 4 also includes a limiting plate 43 fixedly connected inside the protective shell 172. The limiting plate 43 is connected to the mounting plate 31 via... The second connecting pipe 431 is connected to the limit plate 43. The third rotating rod 432 is rotatably connected inside the limit plate 43. One end of the third rotating rod 432 is fixedly connected to the drive plate 433. One end of the drive plate 433 is fixedly connected to the fixed rod 434. The electric shock component 4 also includes a soil plate 44 slidably connected inside the protective shell 172. The surface of the soil plate 44 is provided with a drive groove 441. The bottom of the soil plate 44 is fixedly connected to a suction cup 442. The suction cup 442 is slidably connected inside the air pump 411. Several rotating plates 18 are fixedly connected to the surfaces of the third rotating rod 432, the auger rod 311 and the first rotating rod 211. It should be noted that the bottom of the suction cylinder 411 is fixedly connected to a delivery pipe. A first one-way valve is provided on the surface of the delivery pipe, and a second one-way valve is provided on the surface of the T-tube 421. When the suction cup 442 moves upward, the first one-way valve opens and the second one-way valve closes. When the suction cup 442 moves downward, the first one-way valve closes and the second one-way valve opens. When it is necessary to eliminate the static electricity contained in the powder inside the replenishment box 17, the air source inside the mounting plate 31 enters the limiting plate 43 through the second connecting pipe 431, causing the rotating plate 18 to drive the driving plate 433 and the fixed rod 434 to rotate through the third rotating rod 432. In turn, the fixed rod 434 drives the soil plate 44 to slide up and down inside the protective shell 172 through the driving groove 441. The soil plate 44 continuously delivers nitrogen from the nitrogen box 41 to the gas storage box 42 through the air extraction pipe 411 and the T-shaped pipe 421. When the threshold of the pressure relief valve 423 is reached, the nitrogen in the gas storage box 42 enters the air jet box 424 through the vent pipe 422 and is sprayed out, so that the sprayed nitrogen eliminates the static electricity, thereby ensuring that the powder flowing from the replenishment box 17 into the processing tank 15 does not contain static electricity, thus not affecting the orientation of the powder. In a specific embodiment five, the present invention also provides a magnetic field press method for processing magnetic materials, which specifically includes the following steps: Step 1: Connect the external air source to the anti-bridging component 2. When bridging occurs inside the replenishment box 17, the anti-bridging component 2 will knock and vibrate the replenishment box 17 to prevent the powder inside from bridging and accumulating. Step 2: When the anti-sinking component 2 is in operation, the anti-sinking component 3 is driven synchronously, so that the anti-sinking component 3 conveys the fine powder at the bottom of the inside of the feeding box 17 and remixes it with the coarse powder at the top of the inside, so as to avoid powder stratification. Step 3: When the anti-sinking component 3 is in operation, the static elimination component 4 is driven synchronously, so that the static elimination component 4 eliminates the static electricity inside the feeding box 17, thereby preventing static electricity from affecting powder molding. Step 4: When the replenishment box 17 moves to the top of the processing tank 15, the powder inside the replenishment box 17 enters the interior of the processing tank 15 for filling. Step 5: When the replenishment box 17 returns to its initial state, the stamping cylinder 16 drives the stamping plate 162 to stamp and form the powder inside the processing tank 15 through the telescopic rod 161.
