Description

Technical Field

[0001] The present invention relates to the field of magnet processing, and in particular to a single-side movable fixed neodymium iron boron processing device. Background Art

[0002] Neodymium iron boron (NdFeB), a high-performance rare earth permanent magnet material, is widely used in electronics, motors, and new energy. During the processing of NdFeB bar stock, the entire bar is typically cut along its axis to produce uniformly sized NdFeB sheets. To ensure cutting accuracy, existing techniques typically require clamping and securing the bar at both ends. However, due to the bar's overall length, securing only the ends can lead to vibration in the middle during cutting, resulting in cutting deviations or poor cross-sectional quality. To address this, some processing solutions incorporate multiple fixing points in the middle of the bar to improve stability. However, this multi-point fixing method requires constant adjustment of the clamping position after each section is cut, requiring manual release of the clamp, movement of the clamping structure, and re-fixation. This process is cumbersome, inefficient, and carries the risk of human error. Furthermore, while some existing techniques incorporate a movable fixing structure, they still require complex control mechanisms for locking and releasing, resulting in complex structures and low automation levels, making them unsuitable for industrial applications that demand high processing efficiency and automation. Summary of the Invention

[0003] In order to solve the above problems, the present invention provides a single-side movable fixed NdFeB processing device, which can effectively solve the shortcomings of the prior art.

[0004] The present invention is achieved through the following technical solutions: a single-side movable fixed NdFeB processing device, comprising:

[0005] A bottom plate, with two parallel guide rails provided on both sides of the bottom plate;

[0006] A sliding fixing mechanism is slidably mounted on the two guide rails, and the sliding fixing mechanism includes:

[0007] Two movable seats, each of which is slidably mounted on the guide rail;

[0008] More than one clamping swing arm, each of the clamping swing arms is provided with a fixing ring, the more than one clamping swing arm is rotatably mounted in a swing arm slot provided on the movable seat, the more than one fixing ring is coaxially arranged, one end of the NdFeB bar to be processed is clamped and positioned in each of the fixing rings, and the other end of the NdFeB bar to be processed is positioned and clamped by a clamping table, and the clamping table is provided with a fixed claw plate;

[0009] A cutting notch is formed between each of two adjacent fixing rings, and the NdFeB rod is cut along the cutting notch by an external cutting device to form one or more NdFeB sheets;

[0010] A locking mechanism is provided in each of the fixing rings and the movable seat. When the fixing ring is positioned and clamped on the NdFeB rod, the locking mechanism locks the NdFeB rod.

[0011] After being cut into the NdFeB sheets, the weight of the NdFeB sheets drives the fixing ring and the clamping swing arm to move downward along the rotating end of the clamping swing arm, and the locking mechanism is automatically loosened during this process.

[0012] As a preferred technical solution, the locking mechanism includes one or more clamping blocks, a clamping cavity is formed in the fixing ring, and one or more clamping blocks are arranged around the clamping cavity;

[0013] A locking cavity is provided in each of the fixing rings, and a locking belt is provided in each of the locking cavities. The clamping block is located in the locking cavity and protrudes at one end. The locking belt is wrapped around the outside of each of the clamping blocks. A locking extension section is formed on each side of the locking belt, and the locking extension sections extend into the belt groove in the clamping swing arm.

[0014] As an optimal technical solution, a hollow area is formed in the clamping swing arm, and the locking extension sections extend into the hollow area respectively. A fixing buckle is provided between the two locking extension sections, and a pulling wire is connected between the two fixing buckles. The pulling wire is fixedly connected to the clamping swing arm at one end away from the fixing ring, and each clamping block is locked by pulling the pulling wire.

[0015] As an optimal technical solution, the clamping block is located in the clamping cavity to form a support part on both sides, a support spring is provided at the bottom of the support part, and a spring positioning groove is provided in the locking cavity corresponding to the support part. The support spring is supported and positioned in the spring positioning groove, and the clamping block is lifted up by the support spring.

[0016] As an optimal technical solution, one end of the clamping swing arm passes through the swing arm slot and extends into the movable seat. Two hinged seats are provided on the inner wall of the movable seat. A hinge shaft is provided at each position of the clamping swing arm located at the hinged seat. A torsion spring is installed on each hinge shaft. The torsion spring ensures that the fixing ring is in a coaxial state with the clamping table when the NdFeB sheet is not clamped.

[0017] As a preferred technical solution, an opening window is provided at a position inside the movable seat on each of the clamping swing arms, and the pulling wire is exposed in the opening window.

[0018] As a preferred technical solution, the locking mechanism further includes a driving cylinder, which is fixedly mounted on the end surface of each movable seat, and a driving rod of the driving cylinder extends into the movable seat;

[0019] The driving rod is provided with an extrusion bulge on one side of each clamping swing arm. The extrusion bulge is provided corresponding to the pulling wire. The pulling wire is pulled after being pushed out by the extrusion bulge, and each clamping block is locked by using the locking belt.

[0020] As a preferred technical solution, a rotating belt is provided at one end of each of the extrusion protrusions in contact with the pulling wire, and the rotating belt can rotate back and forth in the placement direction of the clamping swing arm.

[0021] As a preferred technical solution, an electric push rod is provided at the outer end of each guide rail, and a fixed ear is provided at the outer end of each movable seat. The driving end of the electric push rod is connected to the fixed ear, and the movable seat is pushed to move along the guide rail by the electric push rod.

[0022] As an optimal technical solution, a material receiving box is also provided between the guide rails, and one or more material receiving partitions are provided on the material receiving box, and a material receiving cavity is formed between adjacent material receiving partitions. Each of the fixed rings corresponds to a material receiving cavity, and a material receiving magnet is provided on one side of the material receiving partition, and the magnetic properties of the material receiving magnet and the NdFeB sheet are anisotropic.

[0023] The present invention provides a single-side movable fixed NdFeB processing device. This device utilizes a sliding fixed mechanism on a guide rail and employs multiple clamping arms in conjunction with a fixed ring structure to achieve multi-point positioning and clamping of NdFeB bar stock. Each clamping arm is rotatably mounted on a movable seat, and the fixed ring clamps the bar stock in place, providing stable support during the cutting process. This effectively reduces cutting errors caused by suspended bar vibration and improves cutting quality.

[0024] It is particularly noteworthy that the present invention incorporates a clamping block, locking belt, pulling wire, and supporting spring within each retaining ring, forming a compact, responsive locking system. When the NdFeB bar is uncut, the locking structure remains clamped, ensuring the stability of the bar during processing. However, once the bar is cut into sheets, the resulting NdFeB sheet's gravity causes the clamping arm and retaining ring to rotate downward, automatically releasing the locking mechanism and allowing the NdFeB sheet to fall into the corresponding receiving cavity of the receiving box below. This eliminates the need for additional electrical or pneumatic mechanisms, significantly simplifying the structure and achieving integrated linkage between the unloading and release actions.

[0025] The realization of this automatic loosening action depends entirely on the weight change of the NdFeB sheet itself and the downward rotation structure design of the gravity-driven lower swing arm. It has the advantages of no need for additional control devices, instant response, and stability and reliability, which greatly improves the degree of automation and processing efficiency.

[0037] All features disclosed in this specification, or all steps in the disclosed methods or processes, except mutually exclusive features and / or steps, can be combined in any manner.

[0038] Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or similar features. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0039] like Figures 1-8 As shown, a single-side movable fixed NdFeB processing device of the present invention comprises a base plate 1, and two guide rails 7 parallel to each other are provided on both sides of the base plate 1;

[0040] The sliding fixing mechanism is slidably mounted on the two guide rails 7, wherein the sliding fixing mechanism comprises:

[0041] Two movable seats 10, each of the movable seats 10 is slidably mounted on the guide rail 7, and the movable seat 10 can reciprocate along the guide rail 7;

[0042] It also includes more than one clamping swing arm 6, each of which is provided with a fixing ring 5, and the more than one clamping swing arm 6 is rotatably mounted in the swing arm slot 15 opened on the movable seat 10, and the more than one fixing ring 5 is coaxially arranged, and one end of the NdFeB bar 3 to be processed is clamped and positioned in each of the fixing rings 5, and the other end of the NdFeB bar 3 to be processed is positioned and clamped by a clamping table 2, and a fixed claw plate 4 is provided on the clamping table 2. When the fixing ring 5 is fixed on the NdFeB bar 3, the clamping swing arms 6 remain coaxial, and when not cutting, the clamping swing arms 6 maintain this state;

[0043] A cutting notch is formed between two adjacent fixing rings 5. The NdFeB rod 3 is cut along the cutting notch by an external cutting device to form one or more NdFeB sheets. When cutting, start cutting from the end away from the fixed clamping end first, and then cut one by one towards the direction close to the clamping table 2.

[0044] Each of the fixed rings 5 ​​and the movable seat 10 is provided with a locking mechanism. When the fixed ring 5 is positioned and clamped on the NdFeB rod 3, the NdFeB rod 3 is locked by the locking mechanism.

[0045] After the NdFeB sheet is cut, the weight of the NdFeB sheet drives the fixing ring 5 and the clamping swing arm 6 to move downward along the rotating end of the clamping swing arm 6. During this process, the locking mechanism is automatically loosened. After automatic loosening, the material can be automatically taken out, so the sheet can be automatically loosened and unloaded after being automatically cut.

[0046] The locking mechanism includes one or more clamping blocks 20, a clamping cavity 19 is formed in the fixing ring 5, and one or more clamping blocks 20 are arranged around the clamping cavity 19. The NdFeB bar 3 is inserted into each fixing ring 5 and clamped by each clamping block 20.

[0047] Each of the fixing rings 5 ​​is provided with a locking cavity, and each of the locking cavities is provided with a locking belt 24. The clamping block 20 is located in the locking cavity and protrudes at one end. The locking belt 24 is wrapped around the outside of each of the clamping blocks 20. A locking extension section 29 is formed on each side of the locking belt 24. The locking extension sections 29 extend into the belt groove in the clamping swing arm 6. Figure 5 and Figure 6 shown.

[0048] Please continue reading Figure 5 and Figure 6 , hollow areas are formed in the clamping swing arm 6, and the locking extension sections 29 extend into the hollow areas respectively. A fixing buckle 28 is provided between the two locking extension sections 29, and a pulling steel wire 21 is connected between the two fixing buckles 28. The pulling steel wire 21 is fixedly connected to the clamping swing arm 6 at one end away from the fixing ring 5, and the clamping blocks 20 are locked by pulling the pulling steel wire 21. When the pulling steel wire 21 is squeezed, the pulling steel wire 21 is used to drive the locking belt 24 to lock the clamping blocks 20, and then the clamping blocks 20 are used to clamp the NdFeB rod 3.

[0049] Among them, the clamping block 20 is located in the clamping cavity 19, and a support part 25 is formed on both sides respectively. A support spring 26 is provided at the bottom of the support part 25, and a spring positioning groove 27 is provided in the locking cavity corresponding to the support part 25. The support spring 26 is supported and positioned in the spring positioning groove 27, and the clamping block 20 is lifted up by the support spring 26, and each clamping block 20 is always pushed out by the support spring 26.

[0050] Among them, one end of the clamping swing arm 6 passes through the swing arm slot 15 and extends into the movable seat 10. Two hinge seats 17 are provided on the inner wall of the movable seat 10. The clamping swing arm 6 is located at the position of the hinge seat 17, and a hinge shaft 18 is provided on each hinge shaft 18. A torsion spring is installed on the hinge shaft 18. The torsion spring makes the fixing ring 5 coaxial with the clamping table 2 when the NdFeB sheet is not clamped, that is, each fixing ring 5 can remain in a lifted state when the sheet is not clamped, that is, it is coaxial with the NdFeB rod 3. After the NdFeB rod 3 is clamped, each fixing ring 5 is moved and slid in from the other end of the NdFeB rod 3, and then the clamping is completed; after the NdFeB rod 3 is partially cut, the weight of the NdFeB sheet can cause the fixing ring 5 to overcome the elastic force of the torsion spring and descend.

[0051] An opening window 61 is provided at a position inside the movable seat 10 on each of the clamping swing arms 6 , and the pulling wire 21 is exposed inside the opening window 61 .

[0052] The locking mechanism further includes a driving cylinder 11, which is fixedly mounted on the end surface of each movable seat 10, and a driving rod 16 of the driving cylinder 11 extends into the movable seat 10;

[0053] Among them, such as Figure 5 As shown, an extrusion protrusion 22 is provided on the driving rod 16 on one side of each clamping swing arm 6, and the extrusion protrusion 22 is provided corresponding to the pulling wire 21. The pulling wire 21 is pulled after being pushed out by the extrusion protrusion 22, and the locking belt 24 is used to lock each clamping block 20. When the driving cylinder 11 is pushed out, the extrusion protrusion 22 can be used to squeeze the pulling wire 21 in the opening window 61, which can drive the locking belt 24 to lock each clamping block 20. The locking belt 24 can be made of flexible metal material.

[0054] Among them, a rotating belt 23 is provided at the end of each extrusion protrusion 22 that contacts the pulling wire 21. The rotating belt 23 can rotate back and forth in the placement direction of the clamping swing arm 6. The rotating belt 23 can rotate, that is, using the principle of a rotary transmission belt, when the fixed ring 5 clamps the sheet material, the weight of the sheet material is used to lower the clamping swing arm 6, so that the rotating belt 23 rotates relative to the pulling wire 21, so that the pulling wire 21 at the corresponding position can be better rotated and separated from the extrusion protrusion 22. Once the extrusion protrusion 22 is separated from the pulling wire 21, the fixed ring 5 at the corresponding position can be loosened, thereby achieving the purpose of automatically loosening the sheet material.

[0055] Among them, an electric push rod 9 is provided at the outer end of each guide rail 7, and a fixed ear 8 is provided at the outer end of each movable seat 10. The driving end of the electric push rod 9 is connected to the fixed ear 8. The movable seat 10 is pushed to move along the guide rail 7 by the electric push rod 9, and the entire movable seat 10 is driven to move back and forth along the guide rail 7 by the electric push rod 9, thereby changing the clamping point of the bar material.

[0056] Among them, such as Figure 2 As shown, a material receiving box 13 is also provided between the guide rails 7, and one or more material receiving partitions 12 are provided on the material receiving box 13, and a material receiving cavity 14 is formed between adjacent material receiving partitions 12, and each of the fixing rings 5 ​​corresponds to one material receiving cavity 14. A material receiving magnet is provided on one side of the material receiving partition 12, and the magnetism between the material receiving magnet and the NdFeB sheet is anisotropic. When the cut sheet is loose, the NdFeB sheet can be adsorbed by the material receiving magnet to achieve the purpose of automatic material collection. After the NdFeB sheet is magnetically adsorbed by the material receiving magnet, it can be removed manually.

[0057] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included within the scope of protection of the present invention.
