Description

Technical Field

[0001] This invention relates to the field of neodymium iron boron (NdFeB) magnetic sheet processing. More specifically, this invention relates to a grinding apparatus and method for straight-sided double-end-faced magnetic sheets. Background Technology

[0002] Neodymium iron boron (NdFeB) permanent magnets, belonging to the third generation of rare-earth permanent magnets, are characterized by high remanence, high coercivity, and high energy product. Due to their ease of processing, they are widely used in industries such as wind power generation, automobiles, and home appliances.

[0003] Currently, neodymium iron boron (NdFeB) permanent magnet materials are increasingly widely used in fields such as motors and wind power. Based on the magnetic circuit design of motors, the required NdFeB shape generally requires a tile-like form, and the processing of these tile-shaped magnetic sheets mostly utilizes electrical discharge machining (EDM) for cutting. As the performance requirements for magnetic sheets become increasingly stringent, the use of grain boundary strengthening processes to improve performance is becoming more common. However, EDM wire cutting of magnets can cause electrochemical corrosion, and the resulting corrosion layer severely affects the use of NdFeB straight sheets. Furthermore, the grain boundary strengthening process leaves residual slurry in the width direction of the NdFeB straight sheets, preventing the maintenance of normal dimensional and surface roughness requirements in this direction.

[0004] Traditional double-end face grinders utilize upper and lower guide plates and left and right grinding wheels to form a channel that allows the magnetic sheet to pass through. Due to the curvature of the inner arc of the NdFeB straight tile, the plane of the channel formed by the lower guide plate cannot guarantee that the NdFeB straight tile will not wobble during grinding, thus preventing the machining process from being completed. While the relationship between the upper guide plate plane and the end face of the NdFeB square tile is surface contact, effectively preventing the NdFeB square tile from jumping during machining, the outer arc of the NdFeB straight tile changes the relationship between the upper guide plate plane and the curved surface of the NdFeB tile to a single-line contact. This single-line contact cannot prevent the axial rotation of the NdFeB tile. Furthermore, in traditional double-end face grinders, the grinding wheels and the machining channel are separate, often requiring repeated adjustments to ensure that the left and right widths of the grinding wheels and the machining channel are compatible. Summary of the Invention

[0005] This invention provides a grinding device and method for double-end face grinding of NdFeB straight tiles. The device and method can grind the width of NdFeB straight tiles, remove surface slurry residue, and ensure the width consistency and surface roughness of NdFeB straight tiles.

[0006] To achieve these objectives and other advantages of the present invention, in a first aspect, the present invention provides a straight-tile double-end-face grinding apparatus, comprising:

[0007] Feeding power unit;

[0008] Grinding apparatus, comprising:

[0009] The processing channel has a first long strip arc support on the inner wall of each of its two opposite side plates. The feeding power device delivers the material to be processed, which has an arc-shaped cross-section, to the processing channel and places the two inner arc ends of the material to be processed on the first long strip arc support.

[0010] There are two grinding wheel devices, one on the left and one on the right of the processing channel. An arc-shaped groove is provided on each side plate of the processing channel. The grinding wheels of the two grinding wheel devices pass through an arc-shaped groove to grind the two ends of the material to be processed.

[0011] Preferably, the straight tile double-end face grinding device further includes a pressure plate, which is disposed above the material to be processed to prevent the material to be processed from moving upward during the grinding process.

[0012] Preferably, in the straight tile double-end grinding device, the bottom surface of the pressure plate is provided with two elongated arc protrusions, so that they can be tangent to the outer arc of the material to be processed.

[0013] Preferably, in the straight tile double-end face grinding device, the feeding power device includes:

[0014] The feeding channel has a through hole on each of its two side plates;

[0015] The device includes two drive wheels, one on the left and one on the right of the feeding channel. Each drive wheel passes through a through hole and drives the material to be processed in the feeding channel to move forward. The drive wheels are rubber wheels.

[0016] Preferably, the straight tile double-end grinding device has a second elongated arc support portion on the inner wall of each of the two side plates opposite to each other in the feeding channel, wherein the first elongated arc support portion and the second elongated arc support portion are set at the same height.

[0017] Preferably, in the straight tile double-end face grinding device, the feeding power device further includes:

[0018] Slide support plate;

[0019] A dovetail slide is provided on the slide support plate. The dovetail slide includes a left slide and a right slide. A drive wheel device and a corresponding side plate of the feeding channel are fixed on the sliding cover of the left slide and the sliding cover of the right slide. The width of the feeding channel is adjusted by sliding the sliding covers of the left slide and the right slide.

[0020] A chain drive device is disposed below the slide support plate. The chain drive device includes a main sprocket, a driven sprocket, and a chain. The main sprocket is connected to a first motor, and the chain meshes with gears of two drive wheel assemblies, thereby driving the drive wheels in the drive wheel assemblies to rotate.

[0021] Preferably, the straight tile double-end face grinding device further includes a feeding device for feeding materials to the feeding power device, the feeding device comprising:

[0022] Belt conveyor;

[0023] The baffle, including a left baffle and a right baffle, is respectively disposed above the feeding belt in the belt conveyor to guide the conveyed material to be processed. The left baffle and the right baffle are respectively fixed on a first channel bracket to support the left baffle and the right baffle.

[0024] A transition plate is disposed at one end of the feeding belt of the belt conveyor. The transition plate is connected to the feeding channel and is at the same height as the second elongated arc protrusion on the feeding channel.

[0025] Preferably, the straight tile double-end face grinding device further includes:

[0026] The second channel bracket is used to support the two side plates of the processing channel. Four second channel brackets are provided. One end of each second channel bracket is fixed to the housing of the grinding wheel device, and the other end is fixedly connected to the end of the side plate of the processing channel.

[0027] A connecting plate, with its two ends fixed to a second channel bracket, and the side of the connecting plate fixedly connected to the pressure plate to support the pressure plate.

[0028] Preferably, the straight tile double-end grinding device further includes a main base, which is recessed inward to form a groove, and the feeding power device and the grinding device are both disposed in the groove.

[0029] Secondly, the present invention provides a method for grinding the double-end face of a straight tile, applied to the aforementioned grinding apparatus for the double-end face of a straight tile, comprising the following steps:

[0030] First, the feeding device, the feeding power device, and the grinding device are assembled together to form a channel through which the material to be processed can pass continuously.

[0031] Second, place the material to be processed on the two long, arc-shaped support parts of the processing channel, adjust the left and right spacing of the processing channel, and at the same time adjust the distance between the pressure plate and the material to be processed to ensure that the material to be processed does not sway left and right or tilt when passing through the processing channel.

[0032] Third, turn on the belt conveyor and chain drive to ensure that the material to be processed is transported to the processing channel;

[0033] Fourth, turn on the grinding wheel device and gradually adjust the dovetail slide to narrow the distance between the left and right sides of the feeding channel, increase the friction between the drive wheel and the material to be processed, and enable the material to be processed to complete the processing process.

[0034] Fifth, readjust the left and right distance between the two grinding wheels to ensure that the material to be processed reaches the qualified size.

[0035] The present invention has at least the following beneficial effects:

[0036] First, the processing channel of the present invention has a first elongated arc support on the inner wall of each of the two opposite side plates, and the inner arc ends of the material to be processed are respectively placed on the arc support. By utilizing the principle of arc tangency, the width of the inner arc of the NdFeB straight tile is limited, thereby applying a horizontal reaction force to the NdFeB straight tile, and thus limiting the left and right movement of the NdFeB straight tile.

[0037] Secondly, the two grinding wheel devices of the present invention are respectively located on the left and right sides of the processing channel. An arc-shaped groove is provided on each side plate of the processing channel. The grinding wheels of the two grinding wheel devices pass through an arc-shaped groove to grind the two ends of the material to be processed. That is, the present invention assembles the grinding wheel device and the processing channel together. According to different NdFeB straight tile specifications, the adjustment of the distance between the two grinding wheel devices can complete the adjustment action of the processing channel, reducing the adjustment time of the processing channel.

[0038] Third, the present invention includes a pressure plate above the material to be processed to prevent the material from moving upwards during the grinding process. Furthermore, two elongated arc-shaped protrusions are provided on the bottom surface of the pressure plate, tangent to the outer arc of the material to be processed. Due to the gap between the two elongated arc-shaped protrusions, the pressure plate and the outer arc of the NdFeB straight tile are always in double-line contact, restricting the upward movement and axial rotation of the NdFeB straight tile.

[0039] Fourth, the present invention assembles the feeding channel and the drive wheel device together through a dovetail slide. The adjustment of the feeding power device can be completed by adjusting the same amount of movement as the grinding wheel device, thereby reducing the adjustment time of the power device.

[0040] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0054] like Figures 1-10 As shown, the straight tile double-end face grinding device provided in this embodiment of the invention includes: a feeding power device 1; and a grinding device 2, which includes: a processing channel 200, on which a first elongated arc support portion 201 is respectively provided on the inner wall of opposite side plates. The feeding power device 1 feeds the material to be processed 5 with an arc-shaped cross-section to the processing channel 200, and places the inner arc ends of the material to be processed 5 on the first elongated arc support portion 201 respectively; and two grinding wheel devices 210, which are respectively provided on the left and right sides of the processing channel 200. An arc-shaped groove 202 is respectively provided on the side plates of the processing channel 200, and the grinding wheels 211 of the two grinding wheel devices 210 pass through an arc-shaped groove 202 to grind the two ends of the material to be processed 5.

[0055] In the above embodiment, the processing channel 200 is composed of two side plates, left and right. A first elongated arc-shaped support portion 201 is provided on the inner wall of each side plate. Specifically, the first elongated arc-shaped support portion 201 is located at the lower part of the inner wall of the side plate. The first elongated arc-shaped support portion 201 can be an integral structure with the side plate. Preferably, the lower end of the side plate extends inward with a protrusion, forming an arc surface on the top surface of the protrusion. When the inner arc ends of the material to be processed 5 are placed on the first elongated arc-shaped support portion, due to the principle of arc tangency, the width of the inner arc of the NdFeB straight tile is limited, applying a horizontal reaction force to the NdFeB straight tile, thereby limiting the left and right movement of the NdFeB straight tile. In this embodiment of the invention, two grinding wheel devices 210 are respectively disposed on the left and right sides of the processing channel 200. An arc-shaped groove 202 is provided on each of the two side plates of the processing channel 200. Specifically, the arc-shaped groove 202 is located on the bottom surface of the side plate. The grinding wheels 211 of the two grinding wheel devices 210 pass through an arc-shaped groove 202 to grind the two ends of the material to be processed 5. In this embodiment, the two side plates of the processing channel 200 can be fixed to the grinding wheel devices 210 or not; the processing channel 200 has its own supporting component. If the two side plates of the processing channel 200 are fixed to the grinding wheel devices 210, the distance between the two grinding wheel devices 210 can be adjusted to change the distance between the two side plates of the processing channel 200. In this embodiment, the grinding wheel 211 is a resin-bonded grinding wheel, which cuts the surface material in the width direction of the NdFeB straight tile.

[0056] In one specific embodiment, the straight tile double-end face grinding device, such as Figures 2-5 As shown, the grinding device 2 also includes a pressure plate 230, which is positioned above the material to be processed 5 to prevent the material to be processed 5 from moving upwards during the grinding process. Two elongated arc-shaped protrusions 231 are provided on the bottom surface of the pressure plate 230 so that they can be tangent to the outer arc of the material to be processed 5.

[0057] In the above embodiment, the pressure plate 230 is placed in the processing channel 200. Two elongated arcuate protrusions 231 are provided on the bottom surface of the pressure plate 230, allowing them to be tangent to the outer arc of the material to be processed 5. Since there is a certain gap between the two elongated arcuate protrusions 231, the pressure plate 230 and the outer arc of the NdFeB straight tile are always in double-line contact, restricting the upward movement and axial rotation of the NdFeB straight tile. Because the height of the pressure plate 230 needs to be adjusted according to the thickness of the NdFeB straight tile, the pressure plate 230 should be set in a height-adjustable manner. The specific setting of the pressure plate 230 is not specifically limited in this embodiment, as long as the function is achieved.

[0058] In one specific embodiment, the straight tile double-end face grinding device includes a feeding power device 1 comprising:

[0059] The feeding channel 100 has a through hole 102 on each of its two side plates. A second elongated arc support 101 is provided on the inner wall of the opposite side plates of the feeding channel 100. The first elongated arc support 201 and the second elongated arc support 101 are at the same height.

[0060] There are two drive wheel devices 110, which are respectively located on the left and right sides of the feeding channel 100. The drive wheels 111 of the two drive wheel devices 110 pass through a through hole 102 and drive the material to be processed 5 in the feeding channel 100 to move forward. The drive wheels 111 are rubber wheels.

[0061] In the above embodiment, a second elongated arcuate support is provided on the inner walls of the two opposite side plates of the feeding channel 100. The function of the second elongated arcuate support is the same as that of the first elongated arcuate support 201, and the specific arrangement is also the same. The driving wheel 111 ensures that the materials to be processed 5 move forward one after another, and has sufficient force to make the materials to be processed 5 be ground by the grinding wheel 211.

[0062] In one specific embodiment, the straight tile double-end face grinding device, such as Figure 8 As shown, the feeding power unit 1 further includes:

[0063] Slide support plate 130;

[0064] A dovetail slide 120 is mounted on the slide support plate 130. The dovetail slide 120 includes a left slide and a right slide. A drive wheel device 110 and a corresponding side plate of the feeding channel 100 are fixed on the sliding cover of the left slide and the sliding cover of the right slide. The width of the feeding channel 100 is adjusted by sliding the sliding covers of the left and right slides.

[0065] A chain drive device 140 is disposed below the slide support plate 130. The chain drive device 140 includes a main sprocket, a driven sprocket, and a chain. The main sprocket is connected to a first motor 142, and the chain meshes with the gears of the two drive wheel devices 110, thereby driving the drive wheel 111 in the drive wheel device 110 to rotate.

[0066] In the above embodiment, the feeding channel 100 and the drive wheel device 110 are assembled together via the dovetail slide 120. Adjusting the feeding power device 1 only requires adjusting the same amount of movement as the grinding wheel device 210, reducing the adjustment time of the power device. Specifically, the drive wheel device 110 includes a drive wheel 111, a bearing seat 113, a rotating shaft 112, and a gear. The drive wheel device 110 is fixed to the slide cover via the bearing seat 113, and the gear is located below the slide support plate. Two side plates of the feeding channel 100 are respectively fixed to a slide cover. The fixed positions of the side plates and the slide cover are adjustable. For example, an L-shaped support is provided below the side plate, and a rectangular adjustment hole is provided on the horizontal portion of the support. The side plate is fixed to the slide cover through this rectangular adjustment hole. Therefore, the positional relationship between the drive wheel 111 and its corresponding side plate can be adjusted. In addition, the chain drive device 140 also includes a sprocket tensioner 141. The first motor 142 provides power to the master sprocket, slave sprocket and hinge. The sprocket tensioner 141 ensures that the hinge runs smoothly under appropriate tension.

[0067] In one specific embodiment, the straight tile double-end face grinding device, such as Figure 9 As shown, it also includes a feeding device 3, which is used to feed materials to the feeding power device 1. The feeding device 3 includes:

[0068] Belt conveyor 300;

[0069] Baffle 310, which includes a left baffle and a right baffle, is respectively disposed on the feed belt 301 in the belt conveyor 300 to guide the conveyed material to be processed 5 and prevent the material to be processed 5 from moving left and right. The left baffle and the right baffle are respectively fixed on a first channel bracket 320 to support the left baffle and the right baffle.

[0070] A transition plate 330 is disposed at one end of the feeding belt 301 of the belt conveyor 300. The transition plate 330 is connected to the feeding channel 100 and is at the same height as the second elongated arc protrusion 231 on the feeding channel 100.

[0071] In the above embodiment, the belt conveyor 300 includes a feeding belt 301, a drive pulley 302, a driven pulley 303, and a second motor 304. The drive pulley 302 is connected to the output shaft of the second motor 304. Since the left and right baffles are located in the middle of the feeding belt 301, and the first channel support 320 is located on both sides of the feeding belt 301, in order to avoid the baffles 310 affecting the belt conveyor, the left and right baffles are respectively fixed to the first channel support 320 by two elongated plates.

[0072] In one specific embodiment, the straight tile double-end face grinding device, such as Figure 2 As shown, the grinding device 2 further includes:

[0073] The second channel support 220 is used to support the two side plates of the processing channel 200. Four second channel supports 220 are provided. One end of each second channel support 220 is fixed to the outer shell of the grinding wheel device 210, and the other end is fixedly connected to the end of the side plate of the processing channel 200.

[0074] The connecting plate 240 has its two ends fixed to a second channel bracket 220, and the side of the connecting plate 240 is fixedly connected to the pressure plate 230 to support the pressure plate 230.

[0075] In the above embodiment, specifically, the connecting plate 240 has two elongated protrusions on its side, and the pressure plate 230 has two rectangular adjustment holes. Bolts or screws are used to fix the elongated protrusions to the rectangular adjustment holes. Therefore, when the thickness of the material 5 to be processed changes, the height of the pressure plate 230 can be adjusted through the rectangular adjustment holes.

[0076] In one specific embodiment, the straight tile double-end face grinding device further includes a main base 4, which is recessed inward to form a groove. The feeding power device 1 and the grinding device 2 are both disposed within the groove. A water receiving tray is also disposed below the feeding device 3, and the water receiving tray is connected to the base 4. The base 4 allows for cleaning of the bottom surface where the grinding device 2 is disposed and facilitates the cleaning of the NdFeB material removed during grinding.

[0077] Secondly, the present invention provides a method for grinding the double-end face of a straight tile, applied to the aforementioned grinding apparatus for the double-end face of a straight tile, comprising the following steps:

[0078] First, the feeding device 3, the feeding power device 1, and the grinding device 2 are assembled together to form a channel through which the material to be processed 5 can pass continuously.

[0079] Second, place the material to be processed 5 on the two long arc-shaped support parts of the processing channel 200, adjust the left and right distance of the processing channel 200, and at the same time adjust the distance between the pressure plate 230 and the material to be processed 5 to ensure that the material to be processed 5 does not sway left and right or tilt up when passing through the processing channel 200.

[0080] Third, turn on the belt conveyor 300 and the chain drive device 140 to ensure that the material to be processed 5 is conveyed to the processing channel 200.

[0081] Fourth, turn on the grinding wheel device 210 and gradually adjust the dovetail slide 120 to narrow the gap of the feeding channel 100, increase the friction between the drive wheel 111 and the material to be processed 5, and enable the material to be processed 5 to complete the processing process.

[0082] Fifth, readjust the left and right distance between the two grinding wheels 211 to make the material to be processed 5 reach the qualified size.

[0083] The number of devices and processing scale described herein are for the purpose of simplifying the description of the invention. Applications, modifications, and variations of the invention will be readily apparent to those skilled in the art.

[0084] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
