Description

Technical Field

[0001] The present invention relates to the field of laser cutting, and in particular to a laser cutting device and method for samarium cobalt permanent magnet material. Background Art

[0002] Samarium cobalt permanent magnets, with their high magnetic energy product, excellent high-temperature resistance, and good chemical stability, are widely used in new energy vehicles, high-end motors, aerospace, and other fields. In actual manufacturing, samarium cobalt permanent magnets often need to be cut into different specifications and shapes to accommodate various precision components. However, there are many problems with existing cutting technologies: after cutting, the samarium cobalt permanent magnet material that has been divided into multiple pieces will be re-adsorbed together due to its own magnetism. When the magnetic blocks are large, it is difficult to separate them by manpower and external equipment must be used. This not only increases the difficulty of operation but also reduces production efficiency; at the same time, when the existing clamping equipment fixes the samarium cobalt permanent magnet material, its clamping part will block the cutting area, resulting in an incomplete cutting path, affecting the cutting accuracy and material utilization rate; in addition, the residue generated during the cutting process will be attracted by the magnetism of the material and will be re-adsorbed on the surface of the material, increasing the complexity and cost of subsequent cleaning, and the performance of the samarium cobalt permanent magnet material may also be affected by the residual residue.

[0003] In the prior art, patent publication number CN222154126U discloses a high-strength samarium-cobalt magnet cutting device, which includes a support frame, a workbench, a limit block, an adjustment threaded rod, a clamp, a first cylinder, a push plate, a connecting block, an equipment frame, a cutting assembly, and a vacuum cleaner. By rotating the adjustment threaded rod, the clamp secures the samarium-cobalt magnet to be cut on the workbench. The push plate is then pushed by the first cylinder, causing it to move toward the cutting assembly for cutting. A vacuum cleaner is then used to collect the debris generated by the cutting. However, while this technology has improved some of the original problems, there are still areas that require further optimization to better meet actual cutting needs.

[0004] 1. The problem of multiple magnetic blocks adsorbing after cutting: This patent does not take into account the magnetic properties of samarium cobalt permanent magnet materials. After cutting, the multiple magnets that have been separated will be re-adsorbed together due to their own magnetism. Especially for large magnets, they need to rely on external equipment or manpower to forcibly separate them. The operation is inconvenient and may damage the surface of the magnet, affecting the subsequent processing efficiency and product quality.

[0005] 2. Incomplete collection of debris: Although a vacuum cleaner is set up to collect debris, the debris generated by the cutting of samarium cobalt magnets is easily caught in the gaps between multiple magnetic blocks and inside the device. It is difficult to completely remove it with a vacuum cleaner alone, which increases the difficulty of cleaning.

[0006] Therefore, based on the above-stated viewpoint, there is still room for optimization in the existing technology for cutting magnetic plates. Summary of the Invention

DETAILED DESCRIPTION

[0042] The following combination Figures 1 to 12 The embodiments of the present invention are described in detail.

[0043] The embodiment of the present application discloses a laser cutting device and method for samarium cobalt permanent magnet materials. The present application is applied in the cutting process of samarium cobalt permanent magnet materials.

Furthermore, the present application can also drive the magnetic blocks to move alternately through the support unit, cooperate with the blowing component to remove cutting debris, and use the vibration component to realize the grinding and polishing of the edge of the magnetic block, thereby effectively improving the processing quality and efficiency of samarium cobalt permanent magnet materials.

[0044] Example 1: Reference Figure 1 and Figure 2 As shown, it includes a rectangular frame 1, a feeding trough 10, a guide rail 11, a carrying frame 12, a guide plate 13, a mounting groove 14, a strip plate 15, a support unit 2, a support end 3, a blowing assembly 5 and a circular groove 16. A feeding trough 10 is provided on one side of the rectangular frame 1, and a guide rail 11 extending out of the feeding trough 10 is provided in the rectangular frame 1. The carrying frame 12 located in the rectangular frame 1 is slidably installed on the guide rail 11. A guide plate 13 extending into the guide rail 11 is provided at the bottom of the carrying frame 12. When driven by an external force, the carrying frame 12 can move into the rectangular frame 1 through the feeding trough 10, and the guide rail 11 can limit and guide the carrying frame 12 through the guide plate 13; a number of mounting grooves 14 are symmetrically provided on both sides of the carrying frame 12, and a strip plate 15 is commonly installed between two corresponding mounting grooves 14; A laser cutting device (not shown, existing equipment for cutting magnetic plates by laser cutting) is installed inside the rectangular frame 1 .

[0045] A magnetizing device (not shown, existing equipment, used to magnetize the cut magnetic blocks) is also installed in the rectangular frame 1.

[0046] A plurality of circular grooves 16 are formed on the strip plate 15 , and support units 2 for supporting the magnetic plate are installed in the circular grooves 16 .

[0047] A support end 3 for driving the magnetic block to move up and down is slidably provided in the support unit 2 , and the support end 3 includes an electromagnetic plate in contact with the bottom of the magnetic plate.

[0048] A blowing assembly 5 is also provided on the outside of the rectangular frame 1 for removing debris cut from the magnetic block.

[0049] It should be noted that “magnetic plate” is the abbreviation of the uncut plate-shaped samarium cobalt permanent magnetic material plate. After cutting, it is called a “magnetic block” in this embodiment.

[0050] This application also proposes a laser cutting method for samarium cobalt permanent magnet material: S1, support preparation: according to the cutting specifications of the magnetic plate, install several strip plates 15 into the corresponding two installation slots 14, then insert several support units 2 into the corresponding circular slots 16, and finally place the magnetic plate on the support end 3, and the carrying frame 12 drives the magnetic plate through the feeding slot 10 into the rectangular frame 1.

[0051] S2, magnetic plate cutting: the magnetic plate is cut into several magnetic blocks by laser cutting equipment, and each magnetic block has an independent support unit 2 at the bottom for support.

[0052] S3, partial magnetization and debris removal: Partial magnetization is performed through the magnetization device, so that the electromagnetic plate electromagnetically adsorbs the magnetic block and drives the magnetic block to move up and down, so that a height difference is formed between the multiple magnetic blocks, so that when the blowing component 5 blows air toward the rectangular frame 1, the debris on the edge of the magnetic block is blown away.

[0053] S4, complete magnetization and removal: Finally, the magnetization device is used to completely magnetize the magnetic blocks, and the magnetic blocks are taken out of the rectangular frame 1 through the carrying frame 12, and the taken magnetic blocks are staggered and lifted by the support ends 3 to facilitate the removal of the magnetic blocks.

[0054] Reference Figure 3 As shown, the support unit 2 is used to support the magnetic plate; specifically, the support unit 2 includes a cylinder 20, a transmission disc 21 and a reciprocating screw 22, the cylinder 20 is installed in the corresponding circular groove 16, and the top of the cylinder 20 is through-shaped, the support end 3 is inserted on the inner wall of the cylinder 20 by sliding through a keyway, and a transmission disc 21 is rotated on the inner wall of the cylinder 20, a reciprocating screw 22 is provided in the middle of the transmission disc 21, and the upper end of the reciprocating screw 22 extends into the support end 3 and is threadedly connected to it.

[0055] According to the number of magnetic blocks to be cut into by the magnetic plate, the cylinder 20 is installed in the corresponding circular groove 16, and then the magnetic plate is placed together on the support end 3. The supporting frame 12 drives the magnetic plate into the rectangular frame 1, and then the laser cutting device cuts the magnetic plate. When the magnetic plate is cut into magnetic blocks, the transmission disk 21 is driven by external force to drive the reciprocating screw 22 to rotate, and then the reciprocating screw 22 can drive the corresponding support end 3 to move back and forth up and down on the cylinder 20, and simultaneously drive the corresponding magnetic block at the upper end to move. In order to avoid displacement of the magnetic block, the magnetic block can be magnetized with a small amount by the magnetizing device after the magnetic plate is cut, so that the electromagnetic plate in the support end 3 can electromagnetically adsorb the magnetic block to prevent it from shifting or falling off.

[0056] Multiple magnetic blocks are staggered and separated, that is, the magnetic blocks in a row are sequentially called A1 group, A2 group... and so on. The first magnetic plate of A1 group moves upward, and the second magnetic plate of A1 will move downward. Similarly, the first magnetic plate of A2 will move downward, and the second magnetic plate of A2 will move upward, so that the multiple magnetic blocks are staggered and distributed, so that the blowing component 5 can blow off the chips on the edge of the magnetic plate. The purpose of the magnetizing device is also to enable the blowing component 5 to blow off the chips on the magnetic plate to prevent the magnetic force of the chips from being too strong and adsorbed on the magnetic blocks.

[0057] Moreover, during the blowing process of the blowing component 5, the support end 3 can also move up and down repeatedly, driving multiple magnetic plates to move back and forth, so that the edges of the magnetic plates contact and rub against each other to achieve a grinding and polishing effect, and rub off the burrs generated at the cutting edges of the magnetic plates, thereby further improving the applicability of this application.

[0058] Continue to refer to Figure 3 As shown, the support end 3 is in contact with the bottom of the magnetic plate; specifically, the support end 3 includes a sleeve 30 and a transmission plate 31, the sleeve 30 is slidably arranged inside the cylinder 20, the electromagnetic plate is installed in the top of the sleeve 30, and the transmission plate 31 is provided on the inner wall of the sleeve 30, and the reciprocating screw 22 is threadedly connected to the transmission plate 31.

[0059] That is, the reciprocating screw 22 rotates through the transmission plate 31 to drive the sleeve 30 to move up and down in the cylinder 20, so that the sleeve 30 can drive the magnetic block on its top to move up and down, and the electromagnetic plate can electromagnetically adsorb the bottom of the magnetic plate through the outer wall of the sleeve 30.

[0060] Reference Figure 3 、 Figure 4 and Figure 5As shown, a receiving groove 40 is provided on the inner bottom wall of the circular groove 16, and a transmission assembly 4 for driving the transmission disk 21 to rotate is provided in the receiving groove 40; specifically, the transmission assembly 4 includes a receiving groove 40, a rotating shaft 41, a driving gear 42, an inner ring gear 43, a reversing gear 44, a sliding groove 45, a sliding plate 46, an insertion shaft 47, an insertion groove 48, a sliding screw 49, a hexagonal groove 410 and an arc groove 411, and the rotating shaft 41 is rotatably inserted inside the receiving groove 40, and one side of the rotating shaft 41 on the same strip plate 15 rotates through the outer wall of the strip plate 15 and is connected by a belt drive, that is, when the rotating shaft 41 on one side of the same strip plate 15 is driven by an external force, the remaining rotating shafts 41 can be driven to rotate synchronously by a belt drive.

[0061] The outer side of the rotating shaft 41 located in the accommodating groove 40 is sleeved with a driving gear 42, and an inner ring gear 43 is also rotatable on the inner bottom wall of the accommodating groove 40. A reversing gear 44 is rotatably provided on the inner bottom wall of the accommodating groove 40, which is respectively engaged with the outer side of the corresponding driving gear 42 and the inner side of the inner ring gear 43. The rotating shaft 41 can drive the corresponding driving gear 42 to rotate, and when the driving gear 42 rotates, it can drive the inner ring gear 43 to rotate in the opposite direction through the reversing gear 44.

[0062] A sliding groove 45 is provided on the outside of the transmission disc 21, and a sliding plate 46 slides in the sliding groove 45. An insertion shaft 47 is provided at the bottom of the sliding plate 46, and an insertion groove 48 is provided on the upper end of the driving gear 42 and the inner gear ring 43. One side of the insertion shaft 47 is inserted into a corresponding insertion groove 48, that is, the sliding plate 46 can drive the corresponding insertion shaft 47 to move in the sliding groove 45. When the insertion shaft 47 is inserted into the insertion groove 48 on the corresponding driving gear 42, the driving gear 42 can pass through the corresponding insertion groove 48. And the insertion shaft 47 indirectly drives the reciprocating screw 22 to rotate clockwise, so that the reciprocating screw 22 can indirectly drive the corresponding support end 3 to move upward first, and then move back and forth under the drive of the reciprocating screw 22. When the insertion shaft 47 is inserted into the insertion groove 48 on the inner gear ring 43, the inner gear ring 43 can indirectly drive the reciprocating screw 22 to rotate counterclockwise, so that the reciprocating screw 22 first indirectly drives the corresponding support end 3 to move downward first, and then moves back and forth under the drive of the bidirectional thread on the outside of the reciprocating screw 22.

[0063] A sliding screw 49 is rotatably provided on the transmission disk 21, and the sliding screw 49 is threadedly connected to the sliding plate 46. One side of the sliding screw 49 rotates out of the outer wall of the cylinder 20 and is provided with a hexagonal groove 410. An arc groove 411 corresponding to the sliding screw 49 is provided on the outside of the cylinder 20, that is, the lifting and lowering sequence of each corresponding support end 3 is adjusted according to the number of cuttings of the magnetic blocks. By inserting an existing operating tool such as a hexagonal rod into the hexagonal groove 410 through the arc groove 411, the sliding screw 49 can be driven to rotate, and the sliding screw 49 indirectly adjusts the corresponding position of the insertion shaft 47 and the insertion groove 48 on the drive gear 42 or the inner gear ring 43. After the adjustment is completed, the cylinder 20 is installed in the circular groove 16. At this time, the insertion shaft 47 can be inserted into the insertion groove 48 of the corresponding drive gear 42 or the inner gear ring 43.

[0064] Another advantage of each insertion axis 47 being able to be adjusted individually is that, for example, when the magnetic plate is only cut into several strip-shaped magnetic blocks, since the strip-shaped magnetic blocks are long, multiple support ends 3 are required to support them, and the multiple magnetic blocks need to be moved in an interlaced manner. The operator can uniformly adjust the extension axes 64 in the corresponding multiple cylinders 20, thereby further improving the applicability of the present application.

[0065] Reference Figure 6 and Figure 7 As shown, the blowing assembly 5 is used to remove the debris cut from the magnetic block; specifically, the blowing assembly 5 includes a conical cover 50, a through-hole 51, a drop groove 52, a triangular cover 53, a sealing plate 54 and an inclined plate 55, two through-holes are respectively opened on one side and the bottom of the rectangular frame 1, and two conical covers 50 are provided on the outside of the rectangular frame 1, which are respectively connected to the corresponding through-holes, and a through-hole 51 is opened on one side of the rectangular cover.

[0066] Drop grooves 52 are symmetrically provided on the inner bottom wall of the supporting frame 12; and a triangular cover 53 is installed on the strip plate 15 to prevent chips from accumulating on the strip plate 15, and a structural groove corresponding to the circular groove 16 is provided on the triangular cover 53, and the cylinder 20 is located in the structural groove, and a sealing plate 54 is inserted in the part of the circular groove 16 where there is no cylinder 20 inside, and an inclined plate 55 is inserted in the part of the installation groove 14 where there is no strip plate 15 inserted. When there is a need to install the cylinder 20 and the strip plate 15 later, the sealing plate 54 and the inclined plate 55 can be removed.

[0067] That is, after the multiple magnetic blocks are separated, they are connected to the through-hole 51 of the conical cover 50 on one side through an external air supply device (existing equipment for supplying high-pressure gas), and high-pressure gas can be blown into the inside of the rectangular frame 1 through the conical cover 50 and the through-hole. The gas can blow off the chips on the magnetic blocks and drop them on the supporting frame 12. The triangular cover 53, the sealing plate 54 and the inclined plate 55 are all triangular in shape to prevent the accumulation of chips. The debris falling off the triangular cover 53, the sealing plate 54 and the inclined plate 55 will also fall on the supporting frame 12, and finally fall into the conical cover 50 at the lower end through the drop groove 52 and be discharged from the corresponding through-hole 51.

[0068] Example 2: Reference Figure 8 、 Figure 9 、 Figure 10 and Figure 11 As shown, on the basis of Example 1, in order to drive several rotating shafts 41 to rotate, a driving unit 6 is provided on the supporting frame 12; specifically, the driving unit 6 includes a triangular frame 60, a driving shaft 61, a docking groove 62, a docking shaft 63, an extension shaft 64, a driving screw 65, a horizontal shaft 66, a ratchet member 67 and a connecting shaft 68, and the triangular frame 60 is provided on the inner bottom wall of the supporting frame 12, that is, the inclined surface design of the triangular frame 60 can prevent the accumulation of chips, so that the chips can fall off from the inclined surface into the supporting frame 12; several driving shafts 61 corresponding to the mounting grooves 14 are rotatably penetrated on the triangular frame 60, and a hexagonal docking groove 62 is provided at the bottom of the rotating shaft 41 corresponding to the driving shaft 61 on one side, and a docking shaft 63 inserted into the corresponding docking groove 62 is provided at the top of the driving shaft 61.

[0069] Extension shafts 64 are rotatably provided on the inner walls of both sides of the triangular frame 60 , and the extension shafts 64 are connected to the bottoms of the plurality of driving shafts 61 through bevel gear transmission.

[0070] A driving screw rod 65 is rotatably provided in the guide rail 11 and is threadably connected to the guide plate 13 .

[0071] A horizontal shaft 66 is provided for rotation on the outer side of the rectangular frame 1 , and the horizontal shaft 66 is rotatably passed through the inner wall of the rectangular frame 1 and is key-fitted with one end of the extension shaft 64 .

[0072] One side of the driving screw 65 rotates and passes through the guide rail 11 and the outer wall of the rectangular frame 1 and the outside of the horizontal axis 66 are both sleeved with a ratchet piece 67, and the driving directions of the two ratchet pieces 67 are inconsistent. The two ratchet pieces 67 are located on the outside of the rectangular frame 1 and are connected by a belt drive. A connecting shaft 68 rotates on the outside of the rectangular frame 1, and the connecting shaft 68 is connected to the ratchet piece 67 on one side by a belt drive, and the connecting shaft 68 is used to connect to an external drive motor.

[0073] During the specific implementation process, the main shaft of the external drive motor can be connected to the connecting shaft 68 and drive it to rotate. The connecting shaft 68 can drive the two ratchet parts 67 to rotate through belt transmission. Because the driving directions of the two ratchet parts 67 are inconsistent, such as when the external drive motor drives the ratchet part 67 to rotate clockwise, the ratchet part 67 on one side will drive the driving screw 65 to rotate, so that the driving screw 65 can drive the supporting frame 12 into the rectangular frame 1 through the guide plate 13. Then, when the rotating shaft 41 is to be driven to rotate, the connecting shaft 68 drives the ratchet part 67 to rotate counterclockwise, and the ratchet part 67 on the other side will drive the horizontal shaft 66 to rotate. The horizontal shaft 66 can drive the extension shaft 64 to rotate through the keyway cooperation, and the extension shaft 64 can drive the drive shaft 61 to rotate through the bevel gear transmission, so that the drive shaft 61 can drive the rotating shaft 41 to rotate through the cooperation of the docking shaft 63 and the docking groove 62 at the bottom of the corresponding rotating shaft 41.

[0074] When the cutting is completed, the connecting shaft 68 drives the ratchet 67 to rotate clockwise. Since there are two threaded grooves on the outside of the driving screw 65, the supporting frame 12 can be driven out of the rectangular frame 1 through the guide plate 13. After the supporting frame 12 moves out of the rectangular frame 1, the end of the extending shaft 64 protruding from the triangular frame 60 no longer cooperates with the keyway of the end of the horizontal shaft 66.

[0075] Example 3: Reference Figure 12 As shown, on the basis of Example 1 and Example 2: a vibration component 7 is installed at the lower end of the partial rotating shaft 41, which is used to drive the magnetic block to vibrate and accelerate friction and cause debris on the triangular frame 60 and the triangular cover 53 to fall off. The vibration component 7 includes a vertical shaft 70, a swinging groove 71 and a swinging plate 72. The vertical shaft 70 is set at the lower end of the partial rotating shaft 41, and the swinging groove 71 is opened on the outside of the vertical shaft 70. The swinging plate 72 is sleeved on the outside of the vertical shaft 70, and the inner side of the swinging plate 72 extends into the swinging groove 71 and is slidably connected thereto.

[0076] That is, when the rotating shaft 41 rotates, it will drive the swing plate 72 to rotate synchronously and generate vibration through the inner wall of the swing groove 71. The vibration generated by the swing plate 72 will be transmitted upward along the vertical axis 70, thereby driving the rotating shaft 41 and the transmission disk 21 to vibrate; since the transmission disk 21 is connected to the reciprocating screw 22, and the reciprocating screw 22 drives the support end 3 to move up and down through threaded transmission, the vibration will be further transmitted to the support end 3 and the magnetic block.

[0077] When the rotating shaft 41 stops rotating, due to inertia, the portion of the swing plate 72 located in the swing groove 71 will continue to swing due to residual kinetic energy. During the swinging process, the swing plate 72 constantly collides with the inner wall of the swing groove 71. Each collision is accompanied by a sharp change in the state of motion, from high-speed swing to an instantaneous stop, generating a strong impact. The vibration wave generated by this impact will be transmitted layer by layer along the vertical shaft 70, the rotating shaft 41, the transmission plate 21 and other components, and finally transmitted to the support end 3 and the magnetic block. The superposition of vibration waves causes the magnetic block to not only move normally driven by the reciprocating screw 22 when rubbing up and down, but also superimpose high-frequency and strong vibrations. This makes the forces on the edges of the magnetic block more complex and changeable. Fine burrs and uneven areas that were originally difficult to polish can be fully polished under the random impact force generated by the vibration, greatly improving the polishing effect of the magnetic block edge and making the magnetic block surface smoother and flatter.

[0078] At the same time, under the strong action of the vibration wave, the adhesion of the chips attached to the triangular frame 60 and the triangular cover 53 is continuously weakened; the high-frequency impact force generated by the vibration continuously changes the force direction and magnitude of the chips, breaking the equilibrium state of chip adhesion, making it difficult for the chips to continue to adhere to the surface, and they fall onto the supporting frame 12 and are discharged from the equipment through the drop groove 52, effectively avoiding the interference of chip residues on equipment operation and subsequent processing.

[0079] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as exemplary and non-restrictive.

[0080] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
