Description

Technical Field

[0001] The invention relates to the technical field of NdFeB magnet processing, in particular to a continuous cutting device for processing NdFeB magnets of magnetic couplings. Background Art

[0002] Neodymium iron boron magnets are the core components of magnetic couplings. The current processing process of neodymium iron boron magnets includes blank sintering, cutting and segmenting, and magnetization. In terms of cutting process selection, laser cutting is gradually becoming the industry's preferred option due to its micron-level processing accuracy and efficient material removal rate.

[0003] However, the existing laser cutting system still has limitations in actual production: NdFeB magnets will retain residual magnetism after laser cutting. This magnetic interference causes the finished product and waste to remain attached due to magnetic adsorption after cutting, making them difficult to separate. There are currently two mainstream separation methods. One is to separate the two through traditional pneumatic or mechanical gripping devices. The disadvantage of this separation method is that it is easy to cause surface damage to the finished product, reduce the yield rate, and has a high cost. The other is direct manual separation. The disadvantage of this separation method is that in large-scale production, the production rhythm is subject to manual efficiency, and it is difficult to build a continuous production line. Summary of the Invention

[0004] In response to the above-mentioned shortcomings of the prior art, the present invention provides a continuous cutting device for processing NdFeB magnets for magnetic couplings, which can effectively solve the problem in the prior art that NdFeB magnets will retain residual magnetism after laser cutting. This magnetic interference causes the finished product and waste to remain attached to each other due to magnetic adsorption and are difficult to separate.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0006] The present invention provides a continuous cutting device for processing NdFeB magnets for magnetic couplings, comprising:

[0007] Laser cutting machine body;

[0008] A material guide mechanism is installed below the blanking chute in the laser cutting machine body. The material guide mechanism includes a slideway. The slideway is fixedly installed below the blanking chute by a bracket and is used to assist the NdFeB magnets to fall after cutting. A supporting component is installed in the blanking chute to assist the NdFeB magnets to fall onto the slideway.

[0009] The separation mechanism includes a mounting plate, which is fixedly connected between the baffles on both sides of the slide. A cylinder is fixedly connected to the mounting plate. The piston rod of the cylinder points vertically to the bottom plate of the slide and is fixedly connected to the lifting frame 1. The lifting frame 1 is connected to the lifting frame 2 through a scissor plate.

[0010] The lower end of the lifting frame 1 is connected to a propulsion assembly for clamping and pushing the NdFeB magnet in a step-by-step feeding manner, and the lower end of the lifting frame 2 is connected to a stripping assembly for pushing the cut NdFeB magnet rough mold off the waste material. Slots are provided on the slideway and below the lifting frame 1 and the lifting frame 2.

[0011] Among them, a collection box is slidably connected inside the laser cutting machine body and located on both sides of the slide.

[0012] Furthermore, the lifting frame 1 is slidably connected between the two baffles on the slide, and the scissor plate includes two hinged plates arranged in a cross pattern, which are rotatably connected at the center of the intersection through a hinge shaft, and the upper and lower ends of one hinged plate are respectively rotatably connected to the lifting frame 2 and the lifting frame 1, and the upper and lower ends of the other hinged plate are respectively slidably connected to the lifting frame 2 and the lifting frame 1.

[0013] Furthermore, the supporting assembly includes a receiving frame, which is rotatably connected to the blanking trough through a mounting rod, a connecting seat is slidably connected to the mounting rod, the receiving frame is connected to the connecting seat through a torsion spring, and the upper end of the slide is fixedly connected to the mounting rod.

[0014] Furthermore, the end of the supporting frame away from the mounting rod is symmetrically rotatably connected to the limit plate, and the two limit plates are rotatably connected to the supporting frame through a short rod, and are connected to the supporting frame through a second torsion spring. One end of the limit plate adopts a straight line design, and the other end adopts an upward bending design. A clearance groove is opened on the slide and the limit rod is fixedly connected in the clearance groove.

[0015] Furthermore, the propulsion assembly includes a slide, two of which are symmetrically slidably connected to the bottom plate of the slide, the slide is connected to the slide through a reset spring, the upper end of the slide adopts a chamfered design, and the lifting frame is connected to a trapezoidal guide block adapted to the slide through a damping sliding connection, and the slide is rotatably connected to a clamping block through a connecting rod.

[0016] Furthermore, the clamping block adopts a fan-shaped design and an anti-slip groove is provided on the arc surface.

[0034] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. 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 any creative efforts shall fall within the scope of protection of the present invention.

[0035] The present invention will be further described below with reference to the embodiments.

[0036] Example:

[0037] See also Figures 1-10 , the present invention provides a technical solution:

[0038] A continuous cutting device for processing NdFeB magnets for magnetic couplings, comprising:

[0039] Laser cutting machine body 1;

[0040] A material guide mechanism 2 is installed below the blanking chute 11 in the laser cutting machine body 1. The material guide mechanism 2 includes a slideway 21. The slideway 21 is fixedly installed below the blanking chute 11 by a bracket and is used to assist the NdFeB magnets to fall after cutting. A supporting assembly 22 is installed in the blanking chute 11 to assist the NdFeB magnets to fall onto the slideway 21.

[0041] The separation mechanism 3 includes a mounting plate 31, which is fixedly connected between the baffles on both sides of the slide 21. A cylinder 32 is fixedly connected to the mounting plate 31. The piston rod of the cylinder 32 points vertically to the bottom plate of the slide 21 and is fixedly connected to the lifting frame 1 33. The lifting frame 1 33 is connected to the lifting frame 2 35 through a scissor plate 34.

[0042] The lower end of the lifting frame 1 33 is connected to a propulsion assembly 36 for clamping and pushing the NdFeB magnet in a step-by-step feeding manner, and the lower end of the lifting frame 2 35 is connected to a stripping assembly 37 for pushing the cut NdFeB magnet rough mold off the waste material. Slots are provided on the slide 21 and below the lifting frame 1 33 and the lifting frame 2 35.

[0043] Among them, there are collection boxes 4 slidingly connected inside the laser cutting machine body 1 and on both sides of the slide 21. The collection box 4 located directly below the slide 21 is used to collect the finished products separated from the waste after separation by the separation mechanism 3, and the other collection box 4 is used to collect waste, thereby realizing the isolation of finished products and waste, which is convenient for subsequent automated processing procedures or waste recycling.

[0044] It is worth noting that the above-mentioned laser cutting machine body 1 is a model specially developed for the cutting production of magnetic materials. It has corresponding cutting processes and processing methods for cutting patterns of NdFeB magnets of different specifications and models, and can realize automatic loading, unloading and automatic cutting of sintered NdFeB. It is an existing technology and will not be described in detail in this embodiment.

[0045] Specifically, the unloading method of the above-mentioned laser cutting machine body 1 is to directly push the cut NdFeB magnets (including finished products and waste) directly into the collection container provided in the laser cutting machine body 1. After a certain amount of finished products and waste are collected in the collection container, the two are separated manually or by traditional grasping devices. The disadvantage of this separation method is that it adds additional processes and costs, and it is difficult to build a continuous production line.

[0046] This embodiment transforms and optimizes the original collection method, and an additional material guiding mechanism 2 is set in the blanking chute 11. After the cutting is completed, the finished products that cannot be separated due to the magnetic force are pushed into the blanking chute 11 together with the waste materials. They will not fall directly, but will first slide to the supporting component 22 through the slide 21, and then be transferred to the slide 21 through the supporting component 22, and then slide from the high point of the slide 21 to the low point under the action of their own gravity.

[0047] Initially, the piston rod of the cylinder 32 extends, causing the lower end of the lifting frame 1 33 to fall into the corresponding slot, so that when the neodymium iron boron magnet slides to a certain position, it will be blocked by the propulsion assembly 36. At this time, the piston rod of the cylinder 32 contracts, driving the lifting frame 1 33 to move upward. On the one hand, the propulsion assembly 36 cancels the obstruction of the waste. On the other hand, it drives the lifting frame 2 35 to move downward through the shear plate 34, and pushes the finished product magnetically attracted on the waste to fall off the waste through the stripping assembly 37 thereon, and falls into the collection box 4 just below the slide 21. During this period, the waste remains stationary under the pressure of the stripping assembly 37.

[0048] Then, the piston rod of the cylinder 32 extends again, driving the lifting frame 1 33 to descend, so that the propulsion assembly 36 contacts the edge of the stripping assembly 37 and clamps it. During this period, the stripping assembly 37 is driven by the shear plate 34 and moves up synchronously with the lifting frame 2 35 to release the pressure on the waste. As the piston rod of the cylinder 32 continues to extend, the propulsion assembly 36 clamps the waste while causing the waste and the finished product to slide from high to low on the slide 21. A small distance, and then when the piston rod contracts again and drives the lifting frame 2 35 and the stripping assembly 37 downward through the shear plate 34, the action position of the stripping assembly 37 will change, thereby promoting the separation of the remaining finished products from the waste.

[0049] The above process is repeated over and over again, which can automatically separate the finished product from the waste. It can effectively solve the problem in the prior art that the NdFeB magnet will have residual magnetism after laser cutting. This magnetic interference makes the finished product and the waste after cutting still adhere to each other due to magnetic adsorption and are difficult to separate. The separated finished product falls into the collection box 4 under the slide 21, and the waste slides along the slide 21 to another collection box 4, thereby realizing the isolation of the finished product and the waste.

[0050] The lifting frame 1 33 is slidably connected between the two baffles on the slide 21, and the scissor plate 34 includes two hinged plates 341 arranged in a cross pattern, which are rotatably connected at the center of the intersection through a hinge axis. The upper and lower ends of one hinged plate 341 are respectively rotatably connected to the lifting frame 2 35 and the lifting frame 1 33, and the upper and lower ends of the other hinged plate 341 are respectively slidably connected to the lifting frame 2 35 and the lifting frame 1 33.

[0051] Specifically, when the piston rod of the cylinder 32 extends and the lifting frame 1 33 moves downward, the hinged plate 341 fixedly connected to the lifting frame 1 35 will be driven upward to release the pressure of the separation component on the waste. Correspondingly, when the lifting frame 1 33 moves upward with the contraction of the piston rod of the cylinder 32, the hinged plate 341 fixedly connected to the lifting frame 1 35 will be driven downward to drive the stripping component 37 downward to separate the finished product from the waste.

[0052] The supporting assembly 22 includes a supporting frame 221, which is rotatably connected to the blanking chute 11 through a mounting rod 222. A connecting seat 223 is slidably connected to the mounting rod 222. The supporting frame 221 is connected to the connecting seat 223 through a torsion spring 1, and the upper end of the slide 21 is fixedly connected to the mounting rod 222.

[0053] The end of the supporting frame 221 away from the mounting rod 222 is symmetrically rotated and connected to the limiting plate 224. The two limiting plates 224 are both rotatably connected to the supporting frame 221 through a short rod, and are connected to the supporting frame 221 through a second torsion spring. One end of the limiting plate 224 abuts against the lower end of the workbench in the laser cutting machine, and the other end adopts an upward bending design, and the limiting rod 225 is fixedly connected to the slide 21.

[0054] Specifically, the torque of the torsion spring 1 is greater than the torque of the torsion spring 2. Under the joint action of the torsion spring 1 and the limit plate 224, the receiving frame 221 is in a horizontal state when it is not bearing weight. The lower end of the limit plate 224 abuts against the lower end of the laser cutting machine workbench and is also in a horizontal state. Therefore, when the cut NdFeB magnet is pushed into the blanking chute 11, it will be pushed onto the receiving frame 221. When the NdFeB magnet completely reaches the receiving frame 221, its own gravity is greater than the torque of the torsion spring, causing the receiving frame 221 to tilt downward. During the process, since the limit plate 224 is separated from the workbench, it will rise under the action of the torsion spring 2, and abut the end of the NdFeB magnet during the downward tilt of the receiving frame 221 to prevent it from falling. When the receiving frame 221 is about to contact the limit rod 225, the upward bent end of the limit plate 224 will first contact the limit rod 225, so that its straight section will be restored to be parallel to the receiving frame 221, releasing the restriction on the end of the NdFeB magnet, so that the NdFeB magnet can slide from the receiving frame 221 to the bottom plate of the slide 21 under the action of its own gravity.

[0055] In the above process, the advantage of setting the limit plate 224 is that, on the one hand, it can rest against the end of the NdFeB magnet during the downward tilting of the supporting frame 221 to prevent it from falling in the middle; on the other hand, the early contact between the bent section of the limit plate 224 and the limit rod 225 will bring a certain buffering effect, making the contact between the supporting frame 221 and the limit rod 225 smoother, reducing the vibration generated when the supporting frame 221 and the limit rod 225 contact, thereby avoiding excessive displacement of the NdFeB magnet on the supporting frame 221, and always being in a relatively central position on the supporting frame 221, cooperating with the propulsion assembly 36.

[0056] The propulsion assembly 36 includes a slide 361, two of which are symmetrically slidably connected to the bottom plate of the slide 21. The slide 361 is connected to the slide 21 through a return spring 362. The upper end of the slide 361 adopts a chamfered design. The lifting frame 33 is connected to a trapezoidal guide block adapted to the slide 361 through damping sliding. The slide 361 is rotatably connected to a clamping block 363 through a connecting rod. The clamping block 363 adopts a fan-shaped design and an anti-slip groove is provided on the arc surface.

[0057] The upper end of the clamping block 363 is fixedly connected to the rotating seat 365 through a connecting piece 364, and the connecting piece 364 is rotatably mounted on the connecting rod. The rotating seat 365 is fixedly connected to the sliding seat 361 through a torsion spring 361. The upper end of the connecting rod is fixedly connected to the pressing seat 367 through a spring seat 366. The pressing seat 367 and the rotating seat 365 are symmetrically fixedly connected to the adjacent end surfaces with two matching wedge blocks 368.

[0058] Specifically, in the initial state, the piston rod of the cylinder 32 extends, pushing the lifting frame 33 to a relatively lower position. At this time, under the action of the trapezoidal guide block, the two slides 361 are close to each other, the return spring 362 is in an elastic stretching state, and the pressing seat 367 is docked with the rotating seat 365 under the pressure of the lifting frame 33, so that the rotating seat 365, the connecting piece 364 and the clamping block 363 are all in a deflected state. The torsion spring 3 is also in a torsion spring state at this time. When the NdFeB magnet slides along the slide 21 to contact the clamping block 363, it will be blocked by the clamping block 363. Since the NdFeB magnet is near the middle position on the receiving frame 221, there will be no situation where one side of the NdFeB magnet is misaligned with the clamping block 363 due to the misalignment of the two sides.

[0059] Then, when the piston rod of the cylinder 32 contracts and drives the lifting frame 33 to move upward, it will drive the trapezoidal guide block to move upward synchronously. In this process, due to the elastic stretching effect of the return spring 362, the two slides 361 move backward synchronously, driving the two clamping blocks 363 to move backward synchronously, gradually releasing the obstruction to the NdFeB magnet. But at the same time, due to the action of the shear plate 34, the lifting frame 2 35 descends, driving the stripping assembly 37 to move downward synchronously to press the NdFeB magnet, so that the NdFeB magnet will not continue to move downward. The upward movement of the lifting frame 1 33 will also gradually release the pressing effect on the pressing seat 367. The pressing seat 367 moves upward relative to the rotating seat 365 under the elastic force of the spring seat 366. The rotating seat 365 will rotate and reset synchronously under the action of the torsion spring three, and drive the clamping block 363 to rotate and reset synchronously through the connecting piece 364.

[0060] When the piston rod of the cylinder 32 is extended again, on the one hand, the two slides 361 are driven to move in the same direction again through the two trapezoidal guide blocks, driving the clamping blocks 363 to contact the NdFeB magnet synchronously. The difference from the initial contact is that the clamping blocks 363 are now at the two sides of the NdFeB magnet. Then, when the lifting frame 133 continues to move downward, the two clamping blocks 363 are blocked by the NdFeB magnet and cannot continue to feed, which will cause the trapezoidal guide blocks to slide on the lifting frame 133, and the pressing seat 367 will continue to move downward under the pressing action of the lifting frame 133, and the rotating seat 365 will be pushed to rotate through the wedge block 368, thereby driving the trapezoidal clamping blocks 363 to rotate synchronously, and the friction between the anti-slip groove on it and the NdFeB magnet causes it to feed a short distance. The above process is repeated to achieve step-by-step feeding of the NdFeB magnet, thereby changing the working position of the stripping component 37.

[0061] The stripping assembly 37 includes a mounting seat 371 , which is fixedly connected to the lifting frame 2 35 . A plurality of spring rods 372 are evenly fixedly connected to the mounting seat 371 along the circumferential direction.

[0062] Specifically, when the lifting frame 2 35 is driven by the shear plate 34 to descend, the spring rod 372 on the mounting seat 371 corresponding to the finished product will push the finished product to separate from the waste, while the remaining spring rods 372 on the mounting seat 371 press on the waste, providing pressing force during the separation of the clamping block 363 from the waste, thereby preventing the finished NdFeB magnet from falling freely.

[0063] It is worth mentioning that the above-mentioned continuous cutting equipment for processing NdFeB magnets for magnetic couplings also has the following advantages:

[0064] Advantage 1. In this embodiment, the cut NdFeB magnet slides down the slide 21. When the piston rod of the cylinder 32 is extended, the clamping block 363 of the propulsion assembly 36 blocks the waste and feeds it step by step. When the piston rod of the cylinder 32 is retracted, the shear plate 34 drives the stripping assembly 37 to descend, and its spring rod 372 pushes the finished product to separate from the waste. The finished product falls into the collection box 4 just below the slide 21, and the waste continues to be driven by the propulsion assembly 36 to slide to another collection box 4, realizing continuous separation. Through the linkage of the cylinder 32, the shear plate 34, the propulsion assembly 36 and the stripping assembly 37 in the separation mechanism 3, the NdFeB magnet finished product and the waste that are adhered due to residual magnetic adsorption can be automatically separated without manual intervention or traditional grasping devices, thereby solving the problems of low separation efficiency and easy damage to the finished product in the prior art.

[0065] Advantage 2: In this embodiment, when the cut NdFeB magnet is completely pushed onto the receiving frame 221 in a horizontal state, its gravity exceeds the torque of the torsion spring 1, and the receiving frame 221 tilts downward. The limit plate 224 is lifted up under the action of the torsion spring 22 and abuts against the end of the NdFeB magnet to prevent it from falling. When the receiving frame 221 is about to contact the limit rod 225 of the slide 21, the bent end of the limit plate 224 first contacts the limit rod 225 and resets, releasing the restriction on the NdFeB magnet, allowing it to slide smoothly along the receiving frame 221 to the slide 21. The supporting assembly 22 in the blanking chute 11 can assist the NdFeB magnet to fall smoothly into the slide 21. Through the cooperation of the limit plate 224 and the limit rod 225, the displacement of the NdFeB magnet is limited during the tilting process of the receiving frame 221 to prevent it from falling due to vibration or excessive tilt angle, thereby ensuring the stability of material transmission and ensuring that it can be blocked by the clamping block 363 later.

[0066] Advantage 3. In this embodiment, when the piston rod of the cylinder 32 is extended, the trapezoidal guide block descends with the lifting frame 33 and pushes the slide 361 to move toward it, and the clamping block 363 clamps the waste. When the piston rod of the cylinder 32 continues to move downward, the clamping block 363 rotates due to the obstruction of the waste, and the waste is driven to feed a short distance through the action of the wedge block 368 and the torsion spring three. When the piston rod of the cylinder 32 is retracted, the slide 361 moves backward under the action of the return spring 362, releasing the clamping, realizing periodic stepping, and making the stripping assembly 37 act on different positions one by one. The slide 361, return spring 362, clamping block 363 and other structures of the propulsion assembly 36 can drive the waste to slide a small distance on the slide 21, so that the working position of the stripping assembly 37 changes gradually, ensuring that each finished product can be separated from the waste, thereby improving the thoroughness of separation.

[0067] Advantage 4. In this embodiment, when the lifting frame 2 35 descends under the drive of the shear plate 34, the spring rod 372 on the mounting seat 371 contacts the NdFeB magnet, and the spring rod 372 corresponding to the finished product position applies a thrust to separate it from the waste, and the remaining spring rods 372 press the waste to keep it stable. The elastic design of the spring rod 372 can adapt to NdFeB magnets of different sizes, provide uniform pressure, and ensure that the separation process is gentle and impact-free. The mounting seat 371 of the stripping assembly 37 and the circumferentially evenly distributed spring rods 372 can press the waste while separating the finished product from the waste with a flexible thrust, avoiding surface scratches or damage caused by rigid contact, and improving the yield rate.

[0068] Advantage 5. In this embodiment, the finished product falls directly into the collection box 4 directly below the slide 21 after being separated from the waste. The waste slides along the slide 21 to the collection box 4 on the other side driven by the propulsion component 36. No manual sorting is required, and the automatic classification and collection of materials is realized, which reduces the process connection time. The collection boxes 4 on both sides of the slide 21 can collect the separated finished products and waste respectively to avoid mixing the two, which is convenient for subsequent automated processing (such as finished product cleaning, waste recycling, etc.), helping to build a continuous production line and improve production efficiency.

[0069] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
