DETAILED DESCRIPTION

[0026] The present invention is further described in detail below with reference to the accompanying drawings.

[0027] like Figure 1 As shown, the steps and functions of a method for preparing a magnetic material are described in detail below;

[0028] A method for preparing a magnetic material, the method comprising the following steps:

[0029] Step 1: Mix multiple magnetic materials evenly according to proportions, and heat and melt them to obtain a mixed metal melt;

[0030] Step 2: injecting the mixed metal melt into the casting tube 51 through the connecting pipe 33;

[0031] Step 3: During the injection process, the connecting tube 33 and the casting tube 51 move synchronously to increase the efficiency of the magnetic material preparation;

[0032] When in use, iron powder, aluminum powder, nickel powder and silver oxide powder are mixed evenly in a certain proportion, and heated and melted to obtain a mixed metal melt. The mixed metal melt pipeline is pre-connected to the connecting pipe 33, and the rotating bracket I20 and the rotating bracket II31 are driven to rotate together, and then the connecting pipe 33 and the casting tube 51 are moved synchronously, and the mixed metal melt is injected into the casting tube 51, and then the casting process is completed during the movement of the casting tube 51, thereby increasing the processing efficiency, driving the casting tube 51 to continuously move, and sequentially undergoing the processing processes of paramagnetism, cooling, and discharge to complete the processing of the magnetic material;

[0033] In order to facilitate the implementation of a magnetic material preparation method, a magnetic material preparation device is designed. The structure and function of the magnetic material preparation device are described in detail below;

[0034] A magnetic material preparation device comprises a device support 10, the bottom of the device support 10 is rotatably connected to a rotating support Ⅰ20, the device support 10 is fixedly connected to a power mechanism Ⅰ for driving the rotating support Ⅰ20 to rotate, the power mechanism Ⅰ is preferably a servo motor, the top of the device support 10 is rotatably connected to a rotating support Ⅱ31, the device support 10 is fixedly connected to a power mechanism Ⅱ for driving the rotating support Ⅱ31 to rotate, the power mechanism Ⅱ is preferably a servo motor;

[0035] A first telescopic mechanism 32 is fixedly connected to the rotating bracket II 31, a connecting pipe 33 is fixedly connected to the telescopic end of the first telescopic mechanism 32, two second telescopic mechanisms 34 are fixedly connected to the rotating bracket II 31, a rotating motor 35 is fixedly connected to the telescopic ends of the two second telescopic mechanisms 34, and friction wheels I 36 are fixedly connected to the output shafts of the two rotating motors 35;

[0036] Four supporting brackets 41 are fixedly connected to the rotating bracket Ⅰ20, and magnetic poles 42 are fixedly connected to the front and rear sides of each supporting bracket 41, and a rotating bracket Ⅲ44 is rotatably connected to each supporting bracket 41. A power mechanism Ⅲ for driving the rotating bracket Ⅲ44 to rotate is fixedly connected to the supporting bracket 41, and the power mechanism Ⅲ is preferably a servo motor. The left and right sides of the rotating bracket Ⅲ44 are fixedly connected to the cooling pipe 43, and the rotating bracket Ⅲ44 is rotatably connected to the casting tube 51;

[0037] The rotating bracket III 44 is fixedly connected to a third telescopic mechanism 52, and a closed bottom plate 53 is fixedly connected to the telescopic end of the third telescopic mechanism 52, and the closed bottom plate 53 can be buckled and connected to the bottom of the casting tube 51. The casting tube 51 is rotatably connected to a covering top plate 54, and a plurality of air holes 55 are provided on the covering top plate 54. A sliding cylinder I 56 is fixedly connected to the lower side of the covering top plate 54, and a sliding cylinder II 57 is slidably connected in the sliding cylinder I 56. The bottom of the sliding cylinder II 57 is fixedly connected to the bottom of the casting tube 51. A pressure plate 58 is connected, and the pressure plate 58 is slidably connected in the casting tube 51. A compression spring is fixedly connected between the pressure plate 58 and the cover top plate 54. A connecting cavity 59 is fixedly connected to the cover top plate 54. The connecting cavity 59 is communicated with the casting tube 51. An insertion tube 510 is fixedly connected to the connecting cavity 59. The connecting tube 33 can be inserted into the insertion tube 510. A friction wheel II 511 is fixedly connected to the casting tube 51, and the friction wheel II 511 can contact the friction wheel I 36.

[0038] A fourth telescopic mechanism 61 is fixedly connected to the rotating bracket III 44 , and a closing column 62 is fixedly connected to the telescopic end of the fourth telescopic mechanism 61 . The closing column 62 is slidably connected to the connecting cavity 59 , and the closing column 62 can be inserted into the sliding cylinder II 57 to close the sliding cylinder II 57 .

[0039] When in use, iron powder, aluminum powder, nickel powder and silver oxide powder are mixed evenly in a certain proportion, and heated and melted to obtain a mixed metal melt. The mixed metal melt pipeline is pre-connected to the connecting pipe 33, and the power mechanism I and the power mechanism II are started. The output shaft of the power mechanism I drives the rotating bracket I20 to rotate, and the output shaft of the power mechanism II drives the rotating bracket II31 to rotate. When the rotating bracket I20 rotates, it drives the supporting bracket 41 to rotate, and the supporting bracket 41 drives the casting tube 51 to rotate. The rotating bracket II31 drives the first telescopic mechanism 32 to rotate, and the first telescopic mechanism 32 drives the connecting pipe 33 to rotate. The connecting pipe 33 and the casting tube 51 rotate synchronously, and the first telescopic mechanism 32 is started. The first telescopic mechanism 32 can be a hydraulic cylinder or an electric push rod. The telescopic end of the first telescopic mechanism 32 drives the connecting pipe 33 to move, and the connecting pipe 33 moves downward. The connecting pipe 33 is connected to the insertion pipe 510, and the insertion pipe 510 is inserted into the connecting pipe 33;

[0040] The connecting pipe 33 injects the mixed metal melt into the insertion pipe 510. Fig.10 As shown, the mixed metal melt enters the connecting cavity 59 through the insertion tube 510, and then enters the sliding cylinder I 56 and the sliding cylinder II 57, and then enters the bottom of the pressing plate 58, and the casting cylinder 51. As the mixed metal melt at the bottom of the pressing plate 58 continues to increase, the pressing plate 58 continues to move upward, and the pressing plate 58 pushes the sliding cylinder II 57 to slide in the sliding cylinder I 56, and the air on the pressing plate 58 is discharged from the air vent 55;

[0041] When the pressing plate 58 rises to a certain height, the fourth telescopic mechanism 61 is started. The fourth telescopic mechanism 61 can be a hydraulic cylinder or an electric push rod. The telescopic end of the fourth telescopic mechanism 61 drives the closing column 62 to move. The closing column 62 moves downward and is inserted into the sliding cylinder II 57, thereby discharging all the mixed metal melt in the sliding cylinder II 57 into the bottom of the pressing plate 58, thereby ensuring that there is no residual mixed metal melt in the sliding cylinder II 57, so as to prevent the magnetic material from being unable to be demolded after cooling;

[0042] Since the connecting tube 33 and the casting tube 51 move synchronously, the connecting tube 33 is cast during the movement of the casting tube 51, thereby increasing the working efficiency and speeding up the processing of the magnetic material.

[0043] Further, after the mixed metal melt is injected into the casting tube 51, the power mechanism III is started, and the output shaft of the power mechanism III starts to rotate, and the output shaft of the power mechanism III drives the rotating bracket III 44 to rotate, and the rotating bracket III 44 rotates 90°, such as Figure 7 As shown, the casting tube 51 is in a state, the casting tube 51 is placed horizontally, and the second telescopic mechanism 34 is started at the same time. The second telescopic mechanism 34 can be a hydraulic cylinder or an electric push rod. The telescopic end of the second telescopic mechanism 34 drives the rotating motor 35 to move. The rotating motor 35 is started in advance, and the output shaft of the rotating motor 35 starts to rotate. The output shaft of the rotating motor 35 drives the friction wheel I36 to rotate, so that the friction wheel I36 contacts the friction wheel II511, and the friction wheel I36 drives the friction wheel II511 to rotate, and then the friction wheel II511 drives the casting tube 51 to rotate on the rotating bracket III44;

[0044] At the same time, since the casting tube 51 is placed horizontally as shown in FIG. Figure 7 As shown, the two magnetic poles 42 are respectively an "N" pole and an "S" pole, and then the "N" pole and the "S" pole generate a certain magnetic field, and the magnetic field passes through the casting tube 51, and the mixed metal melt in the casting tube 51 is paramagnetized, and then the mixed metal melt can form a magnetic material after cooling;

[0045] Furthermore, during the rotation of the casting tube 51, the cooling water pipe is pre-connected to the cooling pipe 43, and the cooling pipe 43 cools the casting tube 51. When the casting tube 51 rotates a part, the mixed metal melt is driven to rotate so that the mixed metal melt is arranged in the direction of the magnetic field. The other part is to cool the casting tube 51 so that the mixed metal melt is cooled to form a magnetic material.

[0046] like Figure 3As shown, the rotating bracket II 31 performs reciprocating rotation, that is, the rotating bracket II 31 first rotates 45° counterclockwise, and then resets to process the next casting tube 51, thereby ensuring that the casting tube 51 completes the processing technology at each stage during the movement;

[0047] Furthermore, when the mixed metal melt is cooled to form a magnetic material, the third telescopic mechanism 52 is started, and the telescopic end of the third telescopic mechanism 52 drives the closed bottom plate 53 to move downward, and the closed bottom plate 53 leaves the casting tube 51. The compression spring pushes the pressure plate 58 to reset, and the magnetic material is pushed out to complete the processing. The third telescopic mechanism 52 is started again, and the telescopic end of the third telescopic mechanism 52 is reset, and the casting tube 51 is closed to prepare for the next processing. Multiple casting tubes 51 are processed in sequence to quickly prepare magnetic materials.
