Description

Technical Field

[0001] This utility model relates to the field of magnetic powder processing, and in particular to a magnetic powder grinding device. Background Technology

[0002] In the magnetic powder processing, the main purpose of grinding the magnetic powder is to change its shape and size. Grinding ensures that the magnetic powder achieves the required fineness and uniformity, which is crucial for subsequent production of magnetic slurry and ultimately, the production of high-quality products.

[0003] As an important material for making magnetic cores, the appropriate particle size and distribution of magnetic powder help optimize the performance of magnetic cores and improve the performance and consistency of products. In addition, the grinding process can also remove any large particles or irregularly shaped magnetic powder that may exist. If these large particles are not treated, they may mix into the already ground magnetic powder, thus affecting subsequent processing steps.

[0004] In the past, when grinding magnetic powder, the grinding discs were fixedly installed. After grinding, the magnetic powder could only be scooped out manually with a spoon or other tools. This method was often inefficient and could easily cause the magnetic powder to spill out of the spoon, resulting in waste and environmental pollution. It could also cause incomplete feeding, as the magnetic powder at the bottom of the grinding disc was often difficult to scoop out. Utility Model Content

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a magnetic powder grinding device that can improve feeding efficiency and reduce magnetic powder waste during the feeding process.

[0021] Reference Figures 1 to 6 This utility model discloses a magnetic powder grinding device, including: a base plate 100, a grinding disc 200, a column 300, a moving component 400 and a grinding component 500. The base plate 100 is set on the ground, and a first mounting seat 110 is provided on the base plate 100. The base plate 100 is fixedly set on the ground and is used as a mounting base for other components.

[0022] Reference Figures 1 to 6 The grinding disc 200 is hinged to the first mounting base 110. The grinding disc 200 can be upright or laid down. The grinding disc 200 has a grinding space 210 inside, which is used to place magnetic powder. When the grinding disc 200 is upright, it is convenient to load magnetic powder and grind it. After grinding, the grinding disc 200 is laid down, which is convenient to remove the ground powder from the grinding space 210. The grinding disc 200 is generally set as a rotating body. The inner wall of the grinding disc 200 is set as a curved surface, which is convenient for the grinding component 500 to grind the magnetic powder in conjunction with the curved inner wall of the grinding disc 200.

[0023] Reference Figures 1 to 6 The column 300 is mounted on the base plate 100 and is used to install the movable component 400. The movable component 400 is slidably mounted on the column 300 along its extension direction. One end of the grinding component 500 is rotatably mounted on the movable component 400, and the other end of the grinding component 500 is located in the grinding space 210. The other end of the grinding component 500 cooperates with the grinding disc 200 to grind magnetic powder. The grinding component 500 can move along the extension direction of the column with the movable component 400 to move closer to or further away from the grinding disc 200. The column 300 is a conventional setting and will not be described in detail. The grinding component 500 is close to the grinding space 210 to grind magnetic powder, and the grinding component 500 is away from the grinding space 210 to facilitate the tilting of the grinding disc 200, thereby facilitating material feeding. The grinding component 500 is rotatably mounted on the movable component 400. Rotation causes the other end of the grinding component 500 to cooperate with the inner wall of the grinding disc 200 to continuously squeeze the magnetic powder to achieve the grinding effect.

[0024] In some embodiments, refer to Figure 1A positioning plate 600 is provided on the column 300. One end of the positioning plate 600 is set on the column 300, and the other end of the positioning plate 600 is set in the grinding space 210. The positioning plate 600 is used to lock onto the inner wall of the grinding disc 200 to restrict the position of the grinding disc 200. It can be understood that when grinding magnetic powder, the grinding disc 200 needs to be kept upright. The positioning plate 600 is locked onto the inner wall of the grinding disc 200 to prevent the grinding disc 200 from falling over when grinding magnetic powder. The positioning plate 600 can be set according to the actual working conditions, as long as the shape and strength meet the requirements.

[0025] In some embodiments, refer to Figure 1 and Figure 4 The positioning plate 600 is provided with several first waist holes 610. Fasteners detachably connect the positioning plate 600 to the column 300 through the first waist holes 610. It can be understood that the positioning plate 600 is provided with four first waist holes 610. The waist holes have a certain position adjustment function during the connection process, which can better adjust the position of the positioning plate 600 so that the positioning plate 600 reaches the optimal installation position for positioning. When grinding magnetic powder, the grinding disc 200 needs to be kept upright, and the positioning plate 600 is engaged with the inner wall of the grinding disc 200. After grinding is completed, when unloading the magnetic powder in the grinding space 210, remove the fastening bolts installed on any three first waist holes 610 and move the positioning plate 600 out of the grinding space 210 to facilitate subsequent unloading. The number of first waist holes 610 can also be set to other numbers, and the number of waist holes should be greater than or equal to two.

[0026] In some embodiments, refer to Figure 2 , Figure 3 and Figure 5 The grinding disc 200 has a second mounting base 220 at its bottom. The grinding disc 200 is mounted on the first mounting base 110 via the second mounting base 220. The first mounting base 110 and the second mounting base 220 are connected by a hinge. The second mounting base 220 should have the same contact surface contour as the first mounting base 110. The first mounting base 110 and the second mounting base 220 can be set as cylinders or regular polygonal prisms. It should be noted that when the first mounting base 110 and the second mounting base 220 are set as cylinders, a piece needs to be cut off to define a plane, which is used to install the hinge.

[0027] In some embodiments, refer to Figure 3 and Figure 6A rack 310 is provided on the column 300, and a gear 410 is provided inside the moving component 400. The rack 310 meshes with the gear 410 to control the rising or falling of the moving component 400. The use of the rack 310 and gear 410 for transmission has high transmission efficiency and precise transmission control. The rack 310 and gear 410 transmission is a conventional setting and will not be elaborated further. It should be understood that the rack 310 and gear 410 transmission can also be set as a conveyor belt transmission, hydraulic transmission, cylinder transmission, etc.

[0028] In some embodiments, refer to Figures 1 to 6 A power assembly 700 is provided on the moving component 400. The power assembly 700 rises or falls with the moving component 400.
