Detailed Implementation

[0014] The present invention will now be further described with reference to the accompanying drawings.

[0015] like Figures 1 to 8 As shown, a neodymium iron boron (NdFeB) block blanking machine includes a frame, a cross slide module 2, a spindle module 4, a blanking cutter 5, a longitudinal movement module 8, and a processing seat 6. The frame includes a base and a column 12 vertically connected to the base. The cross slide module 2 is mounted on the column 12 and located above the base. The cross slide module 2 is connected to the spindle seat 3 and is used to drive the spindle seat 3 to move along the X and Y axes. The spindle module 4 is mounted on the spindle seat 3 and is vertically arranged. The spindle module 4 is connected to the blanking cutter 5 and is used to drive the blanking cutter 5 to rotate for grinding. The longitudinal movement module 8 is mounted on the base and connected to the processing seat 6. The processing seat 6 is used to fix the NdFeB block 9. The longitudinal movement module 8 is used to drive the processing seat 6 to move, thereby driving the NdFeB block 9 to move for processing.

[0016] The cross slide module 2 is composed of linear modules and is a commercially available product, enabling X-axis and Y-axis movement. The longitudinal movement module 8 also uses a linear module structure and is a mature, existing product. The spindle module 4 is also a commercially available product, and it uses a built-in motor. The cross slide module 2, longitudinal movement module 8, and spindle module 4 are not described in detail here. The frame is not fully shown in the machine frame diagram.

[0017] The neodymium iron boron block 9 is fixed to the bottom of the processing base 6 with glue. Then the spindle module 4 is started. The spindle module 4 processes the neodymium iron boron block 9 through the cross slide module 2 and the longitudinal movement module 8, directly forming a cylindrical neodymium iron boron column 91. There is no need to cut square, roll round and end face grinding, which greatly reduces the number of processes, lowers the cost and improves the production efficiency, and can compress the existing 10-day processing cycle to about 5 days.

[0018] Taking a product with a diameter of D6.3X11 as an example, the processing cost is reduced by 0.1171 yuan per piece. The processing cost of NdFeB 91 pillars using traditional processes is 0.1892 yuan per piece, while the processing cost can be reduced to 0.0721 yuan per piece after using the NdFeB block pillar cutting machine.

[0019] A neodymium iron boron pillar 91 can be magnetized to form a magnet.

[0020] Before processing the NdFeB block 9, the flatness and parallelism of its upper and lower end faces must be ensured so that the resulting NdFeB column 91 can omit the end face grinding step. The NdFeB block blanking machine can guarantee extremely high perpendicularity, ensuring the accuracy and reliability of the product, and can control the perpendicularity within ±0.015mm.

[0021] To improve efficiency, multiple spindle modules 4 can be set up simultaneously, and a row of neodymium iron boron columns 91 can be processed in one go.

[0022] To improve the service life of the hollowing tool 5 and the surface quality of the NdFeB pillar 91, a rotary joint 41 is also provided on the spindle module 4. The rotary joint 41 is connected to a cooling device for cooling the hollowing tool 5 during processing. The spindle of the spindle module 4 is a hollow shaft with an automatic cooling structure.

[0023] The cylindrical cutting tool 5 includes a tool holder 51, an outer cylindrical cutting head 52, and an outer cutting layer 53. Both the tool holder 51 and the outer cylindrical cutting head 52 are cylindrical. The outer cylindrical cutting head 52 is located at the bottom of the tool holder 51 and is concentrically positioned. A water inlet hole 56 is located at the center of the tool holder 51, communicating with the outer cylindrical cutting head 52. The outer cutting layer 53 is located at the end of the outer cylindrical cutting head 52 and is used for cylindrical machining of the NdFeB block 9. The outer cutting layer 53 includes a diamond abrasive layer. The outer cutting layer 53 mainly processes the NdFeB block 9 through grinding. Since the outer cylindrical cutting head 52 is cylindrical and matches the NdFeB column 91 to be machined, a cylindrical NdFeB column 91 can be obtained after the outer cylindrical cutting head 52 is completed. After machining, the NdFeB column 91 can be removed. The NdFeB column 91 is then treated with a solvent to remove the adhesive.

[0024] Grinding can improve the quality of the outer surface of NdFeB pillar 91, eliminating the need for re-grinding the outer surface and reducing process steps.

[0025] To obtain hollow NdFeB pillars 91, the pillar-cutting tool 5 also includes an inner circular cutter head 54 and an inner cutting layer 55. The inner circular cutter head 54 is located at the bottom of the tool holder 51 and inside the outer circular cutter head 52, and the inner circular cutter head 54 and the outer circular cutter head 52 are arranged coaxially. The inner cutting layer 55 is located at the end of the inner circular cutter head 54 and is used to hollow out the NdFeB block 9. The inner cutting layer 55 includes a diamond abrasive layer. The inner circular cutter head 54 and the outer circular cutter head 52 simultaneously cut the NdFeB block 9 to obtain a cylindrical NdFeB pillar 91, eliminating the need for subsequent drilling and reducing process steps.

[0026] To ensure cooling effect, a water inlet 56 is also provided at the bottom of a water passage 57, which is connected to the cavity between the inner round cutter head 54 and the outer round cutter head 52.

[0027] The neodymium iron boron (NdFeB) block core-cutting machine also includes a movable fixed platform 7 and fixing screws. The movable fixed platform 7 is movably inserted into the fixing groove 61 on the top of the processing base 6. The fixing screws are threaded onto the processing base 6, with the ends of the screws abutting against the movable fixed platform 7 to fix the movable fixed platform 7 onto the processing base 6. The NdFeB blocks 9 are fixed on the movable fixed platform 7. To facilitate the fixing and positioning of the movable fixed platform 7, the fixing groove 61 is a T-shaped groove. The two sides of the movable fixed platform 7 are symmetrically arranged on the positioning blocks 71 to form a T-shaped structure that matches the fixing groove 61. The fixing screws abut against the positioning blocks 71.

[0028] The neodymium iron boron cube 9 undergoes precise internal hollowing and cylindrical machining, combining a high-rigidity mechanical structure with a precision servo drive to ensure the stability and accuracy of the machining process.

[0029] This equipment can adjust processing parameters and processes according to different processing needs, thereby enabling the hollowing and cylindrical processing of NdFeB blocks 9 of different specifications and shapes, so that the hollowing machine can meet a variety of complex and customized processing needs.

[0030] The neodymium iron boron block blanking machine eliminates the need for cutting and rolling, directly processing the blocks into blanks, which significantly reduces production steps and saves production and labor costs.

[0031] By eliminating the cutting and rolling process, processing efficiency is significantly improved and the production cycle is shortened.

[0032] Traditional processes generate significant waste during the square-cutting and rounding stages. In contrast, the NdFeB block-shaving machine maximizes raw material utilization, reduces waste, and improves efficiency, thereby lowering costs. Hollow cup products, which are high-performance radial cylinders, typically generate 75% magnetic putty and approximately 25% waste from traditional square-grinding processes. With the block-shaving machine, waste accounts for 65% and magnetic putty 35%. Taking D6.3(M)-D3*11 as an example, this reduces raw material costs.

[0033] The neodymium iron boron block blanking machine does not damage the material during processing, protecting the material's integrity and ensuring product performance.

[0034] Non-destructive processing reduces scrap rates, increases product qualification rates, and saves costs for businesses.

[0035] Because the process does not damage the materials, the resulting products have more stable performance, meeting the diverse needs of customers.

[0036] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these embodiments will all fall within the protection scope of the claims of this utility model.
