Description

Technical Field

[0001] The utility model belongs to the technical field of neodymium iron boron magnets, and specifically relates to a processing and cutting device for neodymium iron boron magnets. Background Art

[0002] Neodymium iron boron magnets are a powerful permanent magnetic material, usually used to manufacture permanent magnets. Due to their strong magnetic properties, neodymium iron boron magnets are widely used in various fields, including motors, generators, sensors, magnets, disk drives, etc.

[0003] A Chinese patent with the publication number CN212542171U discloses a slicing device for neodymium iron boron magnets, which includes a bottom plate. There are two support plates on the top of the bottom plate. A workbench is connected between the tops of the two support plates. A placement groove is opened on the top of the workbench. A blanking hole is opened near the rear side edge of the top of the placement groove. There are two support columns at the edges of the two sides of the top of the bottom plate. A connecting plate is connected between the two support columns. A driving cylinder is installed on the top of the connecting plate. The piston rod of the driving cylinder is vertically downward and its end is connected with a moving plate. A forming knife is arranged at the bottom of the moving plate. For this slicing device for neodymium iron boron magnets, the driving cylinder drives the forming knife to move downward, and the neodymium iron boron magnet blank is cut and formed at one time, saving processing time, thereby improving production efficiency. After cutting, the slices fall from the position of the blanking hole, without manual material taking, reducing safety risks and improving production efficiency.

During operation, a placement cavity 2 is opened at the top of the workbench 1, and a neodymium iron boron magnet is placed in the placement cavity 2 for cutting. Before cutting, different cutting methods are adopted for different neodymium iron boron magnets. For circular neodymium iron boron magnets, they can be placed in the semi-circular placement block 3, and the semi-circular placement block 3 is adjusted by the bidirectional lead screw 4, so as to be applicable to circular neodymium iron boron magnets with various different diameters. Then, the two ends of the circular neodymium iron boron magnet are limited by the sliding block and the locking nut 7. For square neodymium iron boron magnets, the semi-circular placement block 3 is adjusted to an adjacent position, then the square neodymium iron boron magnet is placed on the semi-circular placement block 3, and then the sliding block slides on the locking screw 6 until it slides to a position where it adheres to the surface of the square neodymium iron boron magnet, and then the locking nut 7 locks the sliding block, so as to clamp and fix the square neodymium iron boron magnet. As a whole, it can clamp square and circular neodymium iron boron magnets during cutting, improving the applicable range of cutting.

[0026] Furthermore, as Figure 1 , Figure 2 and Figure 5As shown, the number of the semi-circular placement blocks 3 and the sliding blocks is both set to two; the two semi-circular placement blocks 3 are symmetrically arranged on both sides of the inner wall of the placement cavity 2; the two sliding blocks are symmetrically arranged on both sides of the top of the workbench 1; one end of the bidirectional lead screw 4 penetrates through the workbench 1 and extends to one side of the workbench 1; one end of the bidirectional lead screw 4 is fixedly connected with a rotating handle; two stoppers 8 are fixedly connected to both sides of the top of the workbench 1; the number of the locking screws 6 is set to two, and both ends of the two locking screws 6 are fixedly connected to the surface of the stopper 8; a support bracket 9 is fixedly connected to one side of the top of the workbench 1; two fixed brackets 10 are fixedly connected to both sides of the bottom of the support bracket 9; a reciprocating lead screw 11 is rotatably connected to the surface of the fixed bracket 10; a sliding table 12 is slidably connected to the surface of the reciprocating lead screw 11; a limiting rod is slidably connected to the surfaces of the sliding table 12 and the sliding block; a motor cylinder 13 is fixedly connected to one side of the fixed bracket 10; a motor 14 is fixedly connected to the inside of the motor cylinder 13; the output shaft of the motor 14 is fixedly connected to one end of the reciprocating lead screw 11 through a coupling; an electric telescopic rod 15 is fixedly connected to the bottom of the sliding table 12; the bottom end of the electric telescopic rod 15 is fixedly connected to a cutting machine 16. During operation, the cooperation of the two semi-circular placement blocks 3 and the sliding blocks is set to achieve the clamping function. The rotation of the rotating handle drives the rotation of the bidirectional lead screw 4, thereby driving the two semi-circular placement blocks 3 to move towards or away from each other. The stopper 8 supports the two locking screws 6. In addition, during cutting, the motor 14 inside the motor cylinder 13 works, drives the reciprocating lead screw 11 to rotate through the output shaft, thereby driving the sliding table 12 to move to the corresponding position. Then, the electric telescopic rod 15 at the bottom of the sliding table 12 drives the cutting machine 16 to lift, so as to cut different positions of the neodymium iron boron magnet.

[0027] Further, as Figure 1 、 Figure 3 and Figure 4As shown in the figure, a sliding clamping shaft 17 is slidably connected to the bottom of the workbench 1; one end of the sliding clamping shaft 17 penetrates through the workbench 1 and extends into the placement cavity 2; a placement clamping cylinder 18 is clamped to the end of the sliding clamping shaft 17 located inside the placement cavity 2; the number of the sliding clamping shafts 17 is set to be multiple, and an adjusting clamping plate 19 is fixedly connected to the bottom ends of the multiple sliding clamping shafts 17; a limiting screw rod 20 is threadedly connected to the surface of the adjusting clamping plate 19; the top end of the limiting screw rod 20 is fixedly connected to the bottom of the workbench 1; a fixing nut 21 is threadedly connected to the surface of the limiting screw rod 20 and located at the bottom of the adjusting clamping plate 19. During operation, when the square or circular neodymium iron boron magnet is extremely small and the semi-circular placement clamping block 3 cannot be used for clamping, the sliding clamping shaft 17 can be inserted into the placement cavity 2, and the limiting screw rod 20 is used in cooperation with the fixing nut 21 to limit and fix the sliding clamping shaft 17. Then, the placement clamping cylinder 18 is inserted into the top end of the sliding clamping shaft 17 for placing the square or circular neodymium iron boron magnet. Then, the sliding clamping block is used to clamp and fix both ends of the square or circular neodymium iron boron magnet, further improving the clamping adaptability.

[0028] Working principle: Since the above patent provides a slicing device for neodymium iron boron magnets, although it can save processing time and improve production efficiency, the corresponding placement groove is set to be circular. This means that its applicable range is limited and it can only cut circular neodymium iron boron magnets. Some square neodymium iron boron magnets are difficult to clamp. At the same time, the circular placement groove cannot be adjusted and can only place some matching circular neodymium iron boron magnets for cutting, resulting in the problem that the overall applicable range of cutting needs to be improved. During operation, a placement cavity 2 is opened at the top of the workbench 1, and a neodymium iron boron magnet is placed in the placement cavity 2 for cutting. Before cutting, different methods are adopted for different neodymium iron boron magnets. For circular neodymium iron boron magnets, they can be placed in the semi-circular placement block 3, and the semi-circular placement block 3 is adjusted by the bidirectional lead screw 4, so as to be applicable to circular neodymium iron boron magnets with various different diameters. Then, the sliding block cooperates with the locking nut 7 to limit the two ends of the circular neodymium iron boron magnet. For square neodymium iron boron magnets, the semi-circular placement block 3 is adjusted to an adjacent position, then the square neodymium iron boron magnet is placed on the semi-circular placement block 3, and then the sliding block slides on the locking screw 6 until it slides to a position where it adheres to the surface of the square neodymium iron boron magnet, and then the locking nut 7 locks the sliding block, so as to clamp and fix the square neodymium iron boron magnet. The whole can clamp square and circular neodymium iron boron magnets during cutting, improving the applicable range of cutting. The cooperation of two semi-circular placement blocks 3 and sliding blocks is set to achieve the clamping effect. The bidirectional lead screw 4 is rotated by rotating the rotating handle, so as to drive the two semi-circular placement blocks 3 to move towards or away from each other. The stop block 8 supports the two locking screws 6. In addition, during cutting, the motor 14 inside the motor cylinder 13 works, drives the reciprocating lead screw 11 to rotate through the output shaft, so as to drive the sliding table 12 to move to the corresponding position. Then, the electric telescopic rod 15 at the bottom of the sliding table 12 drives the cutting machine 16 to lift, so as to cut different positions of the neodymium iron boron magnet. When the square or circular neodymium iron boron magnet is extremely small and the semi-circular placement block 3 cannot clamp it, the sliding shaft 17 can be inserted into the placement cavity 2, and the sliding shaft 17 is limited and fixed by the limit lead screw 20 and the fixing nut 21. Then, the placement cylinder 18 is inserted into the top of the sliding shaft 17 for placing the square or circular neodymium iron boron magnet, and then the sliding block is used to clamp and fix the two ends of the square or circular neodymium iron boron magnet, further improving the clamping adaptability. Among them, by setting the bidirectional lead screw 4 to drive the semi-circular placement block 3, the circular neodymium iron boron magnet can be limited and clamped, and can be adjusted to be applicable to circular neodymium iron boron magnets with different diameters. At the same time, the sliding block is used to further clamp the two ends of the circular neodymium iron boron magnet. When clamping the square neodymium iron boron magnet, the semi-circular placement block 3 can be adjusted to an adjacent position, and the square neodymium iron boron magnet is placed on the semi-circular placement block 3,Then, stick the sliding blocks on both sides of the square neodymium iron boron magnet, and lock the sliding blocks with the locking nuts 7, so as to achieve the clamping function and further improve the applicable range of cutting.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
