Description

Technical Field

[0001] This utility model relates to the technical field of neodymium iron boron (NdFeB) production equipment, specifically to a raw material pretreatment device for NdFeB production. Background Technology

[0002] To meet specific size, shape, or performance requirements, neodymium iron boron magnetic blocks need to be sliced ​​during the production process.

[0003] In the prior art, a utility model patent with publication number CN222001993U and titled "A Sintering Device for Sintered NdFeB Magnets" includes a worktable. A first fixing block is provided on the upper left side of the worktable, and a second fixing block is provided on the upper right side of the worktable. A support frame is provided in the middle of the upper part of the worktable. A clamping assembly is provided on the upper side of the worktable. The clamping assembly includes an electric push rod provided on the right end of the first fixing block. A push plate is provided on the right end of the output rod of the electric push rod. A first sliding groove is provided on the left end of the second fixing block. A motor is provided at the front end of the second fixing block. A bidirectional lead screw is fixedly connected to the rear end of the output shaft of the motor. Clamping plates are slidably connected to the front and rear sides of the first sliding groove. A first cylinder is provided at the upper end of the support frame. A pressure plate is fixedly connected to the bottom end of the output rod of the first cylinder. This utility model can clamp and limit the sintered NdFeB magnets, which is beneficial to the flatness of the slices and improves the working efficiency of the device.

[0004] This invention, through reasonable clamping and limiting measures, ensures the flatness and precision of subsequent slicing operations in the NdFeB magnetic block slicing process. However, in the actual production of NdFeB magnetic blocks, to meet the diverse needs of different application scenarios for magnetic field strength distribution and magnetization direction, it is often necessary to precisely cut the ring magnet radially into multiple sector magnets. Existing patented equipment, however, is difficult to flexibly adapt to this specific radial slicing requirement and cannot be easily adjusted according to the specific needs of the operators, thus causing some inconvenience in actual operation. This not only limits the application range of the equipment but also affects work efficiency and product quality to some extent. Utility Model Content

[0005] The purpose of this invention is to provide a raw material pretreatment device for neodymium iron boron production.

[0006] The technical problem solved by this utility model is that existing equipment is inconvenient to radially slice the annular magnet according to the needs of the staff, which brings certain inconvenience to the staff.

[0007] This utility model can be achieved through the following technical solution: a raw material pretreatment device for neodymium iron boron production, including a slicing mechanism on the back of a workbench, a ring magnet fixing mechanism on the workbench, the slicing mechanism including a support plate fixed to the back of the workbench, a hydraulic cylinder fixedly installed at the top of a fixing plate on one side of the support plate, a lifting plate fixedly installed at the output end of the hydraulic cylinder, a servo motor fixedly installed at the bottom end of the lifting plate, a rotating plate fixedly installed at the output end of the servo motor, and at least two slitting blades equidistantly distributed in a circle fixedly installed at the bottom end of the rotating plate.

[0008] A further technical improvement of this utility model is that: the annular magnet fixing mechanism includes a guide column disposed on the workbench and located at the center of the workbench, and at least two arc-shaped clamping plates are horizontally slidably connected on the workbench and located on the outside of the guide column.

[0009] A further technical improvement of this utility model is that: two arc-shaped clamping plates are arranged in a circular array at equal intervals on the worktable, the arc-shaped clamping plates abut against the outer wall of the ring magnet, and an anti-slip layer is provided on the side of the arc-shaped clamping plate that abuts against the ring magnet, so that the equipment can better clamp the ring magnet.

[0010] A further technical improvement of this utility model is that a support plate is fixedly installed on the arc-shaped clamping plate, a screw is threaded to the top of the support plate, and a top clamping plate is rotatably connected to the bottom of the screw and vertically slidably connected to one side of the arc-shaped clamping plate. Rotating the screw causes the top clamping plate to move up and down. The movement of the top clamping plate makes it easier for the equipment to clamp ring magnets of different thicknesses, thereby meeting the different usage needs of the staff.

[0011] A further technical improvement of this utility model is that: the inner cavity of the worktable is provided with a driving assembly for the relative movement of two arc-shaped clamping plates. The driving assembly includes an internal gear ring rotatably connected to the bottom end of the inner cavity of the worktable, and a number of gears equal to the number of arc-shaped clamping plates rotatably connected to the top end of the inner cavity of the worktable. A rack meshing with the gears is slidably connected to the top end of the inner cavity of the worktable through a sliding block. The rack is fixedly connected to the arc-shaped clamping plates. Rotating the internal gear ring causes the gears to rotate through meshing. When the gears rotate, the rack is driven to slide horizontally through meshing.

[0012] A further technical improvement of this utility model is that: the bottom end of the workbench is rotatably connected to a handle fixed to the internal gear ring, and the outer peripheral wall of the handle is provided with anti-slip texture, which makes it easier for the operator to rotate the handle.

[0013] A further technical improvement of this utility model is that the handle is fixed to the worktable by a positioning pin. By using the positioning pin to fix the handle, the reverse rotation of the handle due to external factors is prevented, thus facilitating the use by the staff.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. After limiting the position of the annular magnet, this utility model drives a servo motor to rotate the rotating plate. The rotation of the rotating plate facilitates the change of the position of the bottom slitting blade. By changing its position, the slitting blade is prevented from cutting the clamping part of the annular magnet. After the slitting blade position is adjusted, the hydraulic cylinder drives the lifting plate to move downward, thereby driving the slitting blade to cut the magnet. After the equipment cuts the magnet, the operator can readjust the position of the slitting blade according to the number of pieces the annular magnet needs to be cut into. After adjustment, the magnet can be cut again. This makes the equipment easy to use for radial slicing of the annular magnet according to the operator's needs.

[0016] 2. This utility model facilitates the initial guidance of the annular magnet through the setting of the guide column, which in turn facilitates its subsequent cutting. The relative movement of the arc-shaped clamping plate facilitates the fixation of the outer side of the annular magnet. After the outer side is fixed, the top of the annular magnet is fixed according to its thickness. During fixation, the rotating screw causes the top clamping plate to move downward, which facilitates the fixation of the top. The good positioning of the annular magnet facilitates the subsequent cutting work of the equipment, thereby ensuring the stability of the subsequent cutting work of the equipment.

[0029] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0030] Please see Figure 1-6 As shown, this embodiment provides a technical solution: a raw material pretreatment device for NdFeB production, including a workbench 1. A slicing mechanism is provided on the back of the workbench 1. The slicing mechanism includes a connecting plate 4 fixed to the back of the workbench 1. A fixing plate 41 is fixedly installed on the top of one side of the connecting plate 4. A hydraulic cylinder 42 is fixedly installed on the fixing plate 41. A lifting plate 43 is fixedly installed at the output end of the hydraulic cylinder 42. A servo motor 46 is fixedly installed at the bottom end of the lifting plate 43. A rotating plate 44 is fixedly installed at the output end of the servo motor 46. At least two slitting blades 45 are fixedly installed at the bottom end of the rotating plate 44 by bolts. The two slitting blades 45 are distributed in a circular array at equal intervals at the bottom end of the rotating plate 44. The detachable connection between the slitting blades 45 and the rotating plate 44 facilitates timely replacement of the slitting blades 45 when they are damaged, thereby making the equipment easier for workers to use.

[0031] More specifically, the rotating plate 44 is rectangular in shape, but its actual shape can be selected according to actual usage requirements.

[0032] A ring magnet fixing mechanism is provided on the workbench 1. The ring magnet fixing mechanism fixes at least two arc-shaped clamping plates 3 on the workbench 1. The two arc-shaped clamping plates 3 are distributed in a ring array at equal intervals on the workbench 1. A guide post 2 is fixedly installed on the workbench 1 and located at the center of the workbench 1. The two arc-shaped clamping plates 3 are distributed on both sides of the guide post 2. A support plate 31 is fixedly installed on the arc-shaped clamping plate 3. A screw 32 is threadedly connected to the top of the support plate 31. A top clamping plate 33 is rotatably connected to one side of the arc-shaped clamping plate 3 and is vertically slidably connected to it. An anti-slip layer is provided on the side of the top clamping plate 33 that is in contact with the ring magnet. The anti-slip layer facilitates the top clamping plate 33 to clamp the ring magnet well.

[0033] The inner cavity of the worktable 1 is provided with a drive assembly that enables the two arc-shaped clamping plates 3 to move relative to each other. The drive assembly includes an inner groove 37 opened in the inner cavity of the worktable 1. An inner gear ring 34 is rotatably connected to the bottom end of the inner groove 37. The top end of the inner groove 37 is rotatably connected to a gear 35 with the same number as the support plate 31 via a rotating shaft. The gear 35 meshes with the inner gear ring 34. A rack 36 that meshes with the gear 35 is horizontally slidably connected to the top end of the inner groove 37. The side of the rack 36 away from the center of the inner gear ring 34 is fixedly connected to the arc-shaped clamping plate 3.

[0034] The bottom end of the worktable 1 is rotatably connected to a handle 38, which is fixedly connected to the bottom end of the internal gear ring 34. The handle 38 is fixed to the worktable 1 by a positioning pin 39. The bottom end of the worktable 1 is provided with multiple positioning grooves 310 that cooperate with the positioning pins 39. The multiple positioning grooves 310 are distributed in a ring array at equal intervals at the bottom end of the worktable 1.

[0035] In use, the annular magnet to be cut is placed on the workbench 1 and passes through the guide post 2 of the workbench 1. The guide post 2 facilitates the initial guidance of the annular magnet, which facilitates subsequent cutting. Then, the positioning pin 39 in the handle 38 is removed to release the limitation of the handle 38. After the limitation is released, the handle 38 is rotated to rotate the internal gear ring 34. During the rotation of the internal gear ring 34, at least two gears 35 are driven to rotate through meshing. Similarly, the gears 35 drive the corresponding racks 36 to slide horizontally through meshing. The racks 36 drive at least two arc-shaped clamping plates 3 to move towards the annular magnet. The movement of the arc-shaped clamping plates 3 facilitates the fixation of the outer side of the annular magnet. After the outer side is fixed, the top of the annular magnet is fixed according to its thickness. During fixation, the screw 32 is rotated to move the top clamping plate 33 downward. The downward movement of the top clamping plate 33 facilitates the fixation of the top. The good limitation of the annular magnet facilitates the subsequent cutting work of the equipment.

[0036] After the ring magnet is limited, the servo motor 46 is driven to rotate the rotating plate 44. The rotation of the rotating plate 44 makes it easy to change the position of the bottom cutting blade 45. By changing its position, the cutting blade 45 is prevented from cutting the ring magnet clamping part. After the position of the cutting blade 45 is adjusted, the hydraulic cylinder 42 is driven to drive the cutting blade 45 to cut it through the downward movement of the lifting plate 43.

[0037] After the equipment has finished cutting, the operator can readjust the position of the cutting blade 45 according to the number of parts the ring magnet needs to be cut into, and then cut again.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
