Description

Technical Field

[0001] The invention relates to the technical field of wire cutting, in particular to a multi-wire cutting mechanism for NdFeB blanks. Background Art

[0002] NdFeB blanks are the key starting materials for producing high-performance NdFeB magnets. NdFeB magnets are composed of rare earth metals such as neodymium, iron and boron, and have excellent magnetic properties. They are widely used in motors, sensors, speakers, wind power generation, MRI equipment and other fields. As the front-end process of magnet production, the quality and performance of NdFeB blanks directly affect the magnetic properties and service life of the final product. The multi-wire cutting mechanism uses multiple cutting wires as cutting tools to achieve precise cutting of the blanks through high-speed rotation and movement. During the cutting process, the cutting wires generate electric sparks and contact the blanks, so that the blanks are gradually cut into the required shape and size.

[0003] In the prior art, the wires used for cutting are mostly molybdenum wire, copper wire and galvanized electrode wire, etc. However, during long-term storage or transportation, some cutting wires often form a layer of iron oxide on their surfaces due to the influence of environmental factors, such as oxygen in the air and tiny iron particles. This layer of iron oxide will not only reduce the performance of the cutting wire, such as hardness and wear resistance, but may also affect the cutting accuracy and surface quality, resulting in incomplete cross-section of the NdFeB billet after cutting, or even waste. After long-term use or polishing, the cutting wire may shake or deviate from the predetermined trajectory during the cutting process due to looseness or insufficient tension, which will not only reduce the cutting accuracy, but also cause unnecessary damage to the NdFeB billet, further increasing the scrap rate.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions 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 creative work are within the scope of protection of the present invention.

[0031] See also Figure 1 one Figure 4The present invention provides a technical solution: a NdFeB billet multi-wire cutting mechanism, comprising a body 1, a billet body 15 and a cutting wire 32, the body 1 comprising a lower chassis 11 as a base, the upper top of the lower chassis 11 is fixedly connected with an L-shaped vertical plate 13 and a side plate 14, the upper top of the lower chassis 11 is symmetrically provided with a carrying mechanism 2 for the billet body 15, a cutting mechanism 3 for cutting the billet body 15 is provided on one side of the L-shaped vertical plate 13 close to the side plate 14, and a cutting mechanism 3 for removing iron oxide on the surface of the cutting wire 32 is provided on the upper top of the L-shaped vertical plate 13. A grinding mechanism 4, the upper top of the L-shaped vertical plate 13 is located on one side of the grinding mechanism 4 and is provided with a pressing mechanism 5 for realizing the tightness of the cutting wire 32, the upper top of the L-shaped vertical plate 13 is provided with a guide mechanism 6 for assisting the grinding mechanism 4 and the pressing mechanism 5 to move part of the structure smoothly, the inner top of the L-shaped vertical plate 13 is symmetrically fixedly connected with a hydraulic push rod 131, the upper top of the lower chassis 11 is located at the end of the L-shaped vertical plate 13 and is slidably connected with a protective cover 12, and the inner side wall of the protective cover 12 is symmetrically fixedly connected with an extension plate 121 connected to the telescopic end of the hydraulic push rod 131.

[0032] By adopting the above technical scheme, by integrating the supporting mechanism 2, the cutting mechanism 3, the grinding mechanism 4, the pressing mechanism 5 and the guiding mechanism 6 on the integrated L-shaped vertical plate 13, a fully automated process from blank positioning, cutting operation to cutting wire maintenance is realized. The design of the cutting mechanism 3 can accurately control the movement trajectory of the cutting wire 32, ensuring high-precision and low-loss cutting of the blank body 15. At the same time, the pressing mechanism 5 ensures that the cutting wire is always kept in a taut state, effectively avoiding cutting deviations caused by relaxation, further improving the flatness and smoothness of the cutting surface, and laying a solid foundation for subsequent processing. The setting of the grinding mechanism 4 can remove the iron oxide layer accumulated on the surface of the cutting wire 32 due to long-term use in real time, effectively extending the service life of the cutting wire, reducing the replacement frequency, and reducing the operating cost. The slidingly connected protective cover 12 can not only effectively isolate the sparks, debris and other harmful substances generated during the cutting process, protect the operator from injury, but also reduce the pollution of noise and dust to the environment.

[0033] See also Figure 1 and Fig.10 The supporting mechanism 2 includes a base 21 symmetrically fixedly connected to the upper top of the lower chassis 11, the upper top of the base 21 is slidably connected to a bottom plate 22, the outer wall of the bottom plate 22 is provided with a socket 23 for convenient removal, the upper top of the bottom plate 22 is fixedly connected to a seam plate 24, a plurality of blank bodies 15 are bonded to the upper top of the seam plate 24, the end of the base 21 is threadedly sleeved with a limiting bolt 25, and the outer wall of the limiting bolt 25 is slidably connected to a limiting plate 26 for preventing the bottom plate 22 from detaching.

[0034] By adopting the above technical solution, through the sliding connection design between the base 21 and the bottom plate 22, the user can easily adjust the position of the bottom plate 22 to adapt to the blank body 15 of different sizes or arrangements, making the preparation work before the cutting operation more efficient, reducing the adjustment time, and improving the overall production efficiency. At the same time, the setting of the jack 23 further simplifies the removal and reset process of the bottom plate 22, which is convenient for quickly replacing or adjusting the layout of the blank body 15. The seam plate 24 corresponds to the cutting wire 32, which can effectively disperse the pressure generated during cutting. The fixed connection between the bottom plate 22 and the seam plate 24 ensures the stability of the blank body 15 during the cutting process, ensuring The flatness and accuracy of the cutting surface are ensured. The flatness and rigidity of the seam plate 24 are crucial to ensuring the cutting accuracy as the direct supporting surface of the blank body 15. The combination of the limit bolt 25 and the limit plate 26 provides a reliable locking mechanism for the bottom plate 22. After adjusting the position of the bottom plate, the limit bolt 25 can be rotated to push the limit plate 26 close to the outer wall of the bottom plate 22, effectively preventing it from accidentally sliding or falling off due to vibration or external force during the cutting process. The user can set a corresponding lifting mechanism (not shown in detail in the figure) inside the lower chassis 11 to drive the supporting mechanism 2 to rise, thereby cooperating with the cutting wire 32 to achieve its cutting work.

[0035] See also Figure 3 one Figure 5 The cutting mechanism 3 includes a plurality of rollers 31 rotatably connected to the inner wall of the L-shaped vertical plate 13, a plurality of cutting wires 32 are evenly arranged and sleeved on the outer wall of the rollers 31, and the cutting wires 32 are trapezoidal in shape under normal conditions, and the outer wall of the L-shaped vertical plate 13 is fixedly connected to a first motor 33, and the output end of the first motor 33 is fixedly connected to a first driving shaft 34, and the first driving shaft 34 extends to the inner wall of the L-shaped vertical plate 13, and the end of the first driving shaft 34 is fixedly connected to one of the rollers 31, and the ends of the plurality of rollers 31 close to the first motor 33 are fixedly sleeved with a transmission sprocket 35, and the outer wall of the transmission sprocket 35 is sleeved with a transmission chain 36 for transmission, and the transmission sprocket 35 and the transmission chain 36 are chain driven.

[0036] By adopting the above technical solution, the first motor 33 drives the first drive shaft 34 to rotate, thereby driving the roller 31 fixedly connected thereto to rotate, and utilizing the chain transmission mechanism, namely the transmission sprocket 35 and the transmission chain 36, to realize the synchronous and stable rotation of all rollers 31, thereby ensuring the uniform distribution and high-speed operation of the cutting wires 32 on the outer wall of the roller 31, greatly improving the cutting efficiency. At the same time, under normal conditions, the cutting wires 32 are arranged in a trapezoidal shape, which can more effectively disperse the cutting force, reduce the cutting resistance, and further increase the cutting speed, thereby significantly improving the overall production capacity. The precise rotation control of the roller 31, combined with the stability of the chain transmission, ensures the cutting The uniform tension and stable path of the cutting wire 32 during the cutting process not only improve the flatness of the cutting surface, but also reduce the cutting error caused by the shaking of the cutting wire or deviation from the predetermined trajectory, thereby ensuring the stability and consistency of the cutting quality. The design of the cutting mechanism 3 allows the user to adjust the number and arrangement of the rollers 31 as needed to adapt to the blank bodies 15 of different sizes, shapes or thicknesses. At the same time, the chain drive mechanism ensures the synchronization between the rollers 31, and maintains a stable cutting effect even under different load conditions. The first drive shaft 34 in the figure can be flexibly adjusted and does not have to be fixedly connected to the middle roller 31.

[0037] See also Figure 6 one Fig. 9 The pressing mechanism 5 includes a double-axis motor 51 fixedly connected to the inner top of the L-shaped vertical plate 13, and the two output ends of the double-axis motor 51 are respectively fixedly connected to the main shaft 511 and the secondary shaft 513, and the lower bottom end of the double-axis motor 51 is fixedly connected to the second gear seat 55, and the inner top and inner side wall of the second gear seat 55 are respectively rotatably connected to the fifth bevel gear 552 and the fourth bevel gear 551, and the fifth bevel gear 552 and the fourth bevel gear 551 are arranged in right angle meshing, and the end of the secondary shaft 513 extends to the inner top of the second gear seat 55 and is fixedly connected to the end of the fifth bevel gear 552, and the end of the fourth bevel gear 551 is fixedly connected to the rotating shaft 52, and the outer wall of the rotating shaft 52 is symmetrically sleeved with a second bearing frame 53 for support, and the end of the second bearing frame 53 is fixedly connected to the inner top of the L-shaped vertical plate 13.

[0038] By adopting the above technical solution, the main shaft 511 and the secondary shaft 513 are driven by the dual-axis motor 51, so that the pressing mechanism 5 can accurately adjust the tension of the cutting wire 32 to ensure that the cutting wire always maintains the best tension during the cutting process. The secondary shaft 513 transmits the rotational power to the rotating shaft 52 through the right-angle engagement of the fifth bevel gear 552 and the fourth bevel gear 551, thereby realizing the downward pressure regulation of the cutting wire 32, ensuring the uniform distribution of the downward force, and avoiding the cutting error caused by the uneven tension of the cutting wire. The bevel gear transmission mechanism, that is, the right-angle engagement of the fifth bevel gear 552 and the fourth bevel gear 551, is adopted to realize the efficient conversion and transmission of power, reduce the energy loss in the transmission process, and improve the transmission efficiency. The second bearing frame 53 symmetrically sleeved on the outer wall of the rotating shaft 52 not only provides a stable support for the rotating shaft, but also enhances the rigidity and stability of the entire pressing mechanism.

[0040] By adopting the above technical scheme, the rotating plate 56 is driven to rotate by the rotating shaft 52, which in turn drives the sleeve plate 57 to rotate and sleeve on the outer wall of the arc-shaped gear ring 58, and the synchronous movement of the synchronous plate 581, thereby realizing the synchronous rotation of the two arc-shaped gear rings 58, ensuring the stable meshing transmission between the second gear 541 and the arc-shaped gear ring 58, so that the two third racks 543 can move synchronously, thereby driving the pressure plate 59 to press down at a uniform and stable speed. The precise and synchronous pressing mechanism greatly improves the stability and accuracy of the cutting wire 32 during the cutting process. By adjusting the speed and direction of the dual-axis motor 51, the rotating plate 56, the sleeve plate 57, the arc-shaped gear ring 58 and the pressure plate 59 can be flexibly controlled, so that the pressing mechanism 5 can be accurately adjusted according to different cutting requirements to adapt to the blank body 15 of different materials, thicknesses and shapes.

[0041] See also Figure 6 one Figure 8 The grinding mechanism 4 includes a first gear 41 rotatably connected to the inner wall of the L-shaped vertical plate 13, and the first rack 45 and the second rack 46 are respectively meshed and transmitted on both sides of the first gear 41, and the ends of the first rack 45 and the second rack 46 are fixedly connected to the auxiliary plate 451, and the opposite side of the auxiliary plate 451 is fixedly connected to the grinding plate 48 for grinding, the outer wall of the first gear 41 is fixedly connected to the transmission rod 43, and the outer wall of the transmission rod 43 is fixedly connected to the side close to the first gear 41, and the end of the main shaft 511 is fixedly connected to the second synchronization wheel 512, and the outer walls of the first synchronization wheel 411 and the second synchronization wheel 512 are provided with a synchronization belt 412 for transmission, and the outer wall of the transmission rod 43 is symmetrically provided with a first bearing frame 42 for support, and the end of the first bearing frame 42 is fixedly connected to the inner top end of the L-shaped vertical plate 13.

[0042] By adopting the above technical scheme, the second synchronous wheel 512 is driven to rotate by the main shaft 511, and the transmission effect of the synchronous belt 412 is utilized to drive the first synchronous wheel 411 and the first gear 41 fixedly connected thereto to rotate synchronously, which not only realizes the precise synchronization between the main shaft 511 and the grinding mechanism 4, but also ensures that the first gear 41 can transmit power stably and efficiently. The rotation of the first gear 41 further drives the first rack 45 and the second rack 46 to move in opposite directions, thereby driving the auxiliary plate 451 and the grinding plate 48 thereon to grind the cutting wire 32 evenly and efficiently. At the same time, the symmetrical sleeve of the first bearing frame 42 provides a stable support for the transmission rod 43. By adjusting the rotation speed and direction of the main shaft 511, the first gear 41, the first rack 45 and the second rack 46 can be flexibly controlled, thereby adjusting the moving speed and grinding force of the grinding plate 48, that is, the contact state between the grinding plate 48 and the cutting wire 32.

[0043] See also Figure 6 one Fig.11 , the end of the transmission rod 43 away from the first gear 41 is fixedly sleeved with a first bevel gear 441, the inner top end of the L-shaped vertical plate 13 is fixedly connected to the first gear seat 44 on the side close to the first bevel gear 441, the inner side wall of the first gear seat 44 is symmetrically rotatably sleeved with the second bevel gear 442 and the third bevel gear 443, the first bevel gear 441 is meshed with the second bevel gear 442 and the third bevel gear 443 for transmission, the outer side wall of the first gear seat 44 is symmetrically rotatably connected with a capstan 47, and the two capstans 47 are coaxially connected to the second bevel gear 442 and the third bevel gear 443 respectively, the outer wall of the capstan 47 is wound with a cable 471, the end of the cable 471 is fixedly connected with a hook 472, the upper top ends of the two auxiliary plates 451 are fixedly connected with a fixed bracket 473, the hook 472 is sleeved inside the fixed bracket 473, and the two cables 471 move in opposite directions.

[0044] By adopting the above technical solution, the meshing transmission of the first bevel gear 441, the second bevel gear 442 and the third bevel gear 443 realizes the efficient and stable conversion of power from the transmission rod 43 to the capstan 47, which not only enriches the transmission mode of the grinding mechanism 4, but also enables the power to be distributed to the two capstans 47 as needed, and realizes the precise control of the cable 471 and the hook 472. At the same time, since the meshing angle of the bevel gears can be adjusted, the rotation direction and speed of the capstan 47 can be flexibly adjusted according to actual needs, so as to meet the needs of different grinding tasks.

The fixed connection and symmetrical rotating sleeve design of the first gear seat 44 provide stable support and limiting effects for the second bevel gear 442 and the third bevel gear 443, ensuring that the meshing transmission between the bevel gears is stable and reliable.

The inner top of the L-shaped vertical plate 13 is located on both sides of the first gear 41 and is fixedly connected to the first slide rail 61. The second rack 46 is slidably connected to the inside of the first slide rail 61. The side of the side plate 14 close to the grinding mechanism 4 is symmetrically fixedly connected to the second slide rail 62, and the end of the auxiliary plate 451 is slidably connected to the inside of the second slide rail 62.

[0046] By adopting the above technical scheme, the third rack 543 is guided by the third slide rail 63 for sliding, and the second rack 46 is guided by the first slide rail 61 for sliding, so as to ensure the stability and accuracy of these two key transmission components during the movement process, which not only reduces the transmission error caused by motion deviation, but also improves the operation efficiency and reliability of the whole mechanism. At the same time, the sliding guidance of the auxiliary plate 451 by the second slide rail 62 further enhances the stability and accuracy of the grinding plate 48 during the grinding process, thereby ensuring the uniformity and consistency of the grinding effect. The symmetrical distribution and fixed connection of the third slide rail 63, the first slide rail 61 and the second slide rail 62 not only make the whole mechanism compact and reasonably laid out, but also effectively save equipment space.

[0047] See also Figure 1 one Fig.11The grinding mechanism 4 and the pressing mechanism 5 are arranged in parallel, the pressing plate 59 and the two auxiliary plates 451 are located above the cutting wire 32, and there is a corresponding gap between the two auxiliary plates 451, and the sizes of the pressing plate 59 and the auxiliary plates 451 do not exceed the gap between two of the rollers 31.

[0048] By adopting the above technical solution, by arranging the grinding mechanism 4 and the pressing mechanism 5 in parallel, not only the space above the cutting wire 32 is fully utilized, but also the two mechanisms can independently grind or press down the cutting wire 32. The pressing plate 59 and the two auxiliary plates 451 are both located above the cutting wire 32, and their sizes do not exceed the gap between two of the rollers 31. The cutting wire 32 can be accurately grinded and pressed down without interfering with the normal operation of the rollers 31. The parallel arrangement of the grinding mechanism 4 and the pressing mechanism 5, and the precise positioning of the pressing plate 59 and the auxiliary plates 451 ensure that they will not collide or interfere with the rollers 31 or other components during operation, thereby reducing downtime and maintenance costs caused by equipment failure.

[0049] Detailed description of the grinding mechanism 4: Due to storage or transportation reasons, iron oxide is attached to the surface of the cutting wire 32. In order not to affect the use and reduce manual intervention, the user can control the output end of the dual-axis motor 51 to drive the main shaft 511 and the second synchronous wheel 512 to rotate, and the outer walls of the second synchronous wheel 512 and the first synchronous wheel 411 are sleeved with a synchronous belt 412. When the synchronous belt 412 rotates, it can drive the first gear 41 and the transmission rod 43 to rotate. A first bevel gear 441 is also provided on the outer wall of the transmission rod 43, and the first bevel gear 441 and the first gear 41 will move synchronously. At this time, the first rack 45 and the second rack 46 at both ends of the first gear 41 will move in opposite directions, and the auxiliary plate 451 will also move one upward and the other downward. Since a grinding plate 48 is provided on the opposite side of the auxiliary plate 451, when the grinding plate 48 contacts the cutting wire 32, due to the continuous movement of the cutting wire 32, The effect of removing the iron oxide on the surface of the cutting wire 32 can be achieved. For the stability of the auxiliary plate 451 during movement, the second bevel gear 442 and the third bevel gear 443 meshing with the first bevel gear 441 will also rotate in different directions, thereby driving the cables 471 on the outer walls of the two capstans 47 to work, and the two cables 471 are in a winding state and a release state, respectively. If the first rack 45 moves upward, one of the capstans 47 will wind up the cable 471, and the second rack 46 moves downward, then the other capstan 47 will release the cable 471, and vice versa. In this way, the movement of the auxiliary plate 451 can be stabilized. In the process of the first rack 45 and the second rack 46 descending, in order to stabilize the two first slide rails 61 fixedly connected to the top of the L-shaped vertical plate 13, the two auxiliary plates 451 are also guided by the second slide rails 62:

[0050] Detailed description of the pressing mechanism 5: a plurality of cutting wires 32 are wound around the outer wall of the roller 31. When the output end of the first motor 33 drives the first drive shaft 34 to rotate, it can drive one of the rollers 31 to rotate, and then drive the remaining rollers 31 to rotate through the transmission sprocket 35 and the transmission chain 36. At this time, the cutting wire 32 is connected to the external terminal, and generates electric sparks to achieve the cutting of the blank body 15. Due to long-term use and installation problems, the cutting wire 32 will become loose at this time, and the cutting wire 32 in the loose state will have a certain impact on the cross-section of the blank body 15, reducing the processing accuracy. At this time, one of the output ends of the dual-axis motor 51 can be controlled to drive the secondary shaft 513 to rotate, and drive the fourth bevel gear 551 and the fifth bevel gear 552 to rotate. When the fourth bevel gear 551 rotates After the movement, the rotating shaft 52 and the rotating plate 56 rotate synchronously. Since the rotating plate 56 and the arc-shaped gear ring 58 are connected by a sleeve plate 57, the arc-shaped gear ring 58 realizes circular motion with the help of the rotating plate 56 and the sleeve plate 57, and the arc-shaped gear ring 58 is meshed with the second gear 541 for transmission, and the second gear 541 and the third gear 542 move coaxially. Therefore, the third rack 543 meshed with the third gear 542 will drive the pressure plate 59 to move downward, and squeeze the cutting wire 32 through the pressure plate 59, so as to achieve the tightening of the cutting wire 32 and avoid the cutting wire 32 being too loose, resulting in reduced processing accuracy. In the process of the two third racks 543 synchronously driving the pressure plate 59 to move downward, it will be guided by the third slide rail 63 connected to the top end of the L-shaped vertical plate 13 to achieve the purpose of stability and ensure its position.
