Description

Technical Field

[0001] This utility model relates to the technical field of magnetic core material processing equipment, and in particular to a device for deburring the four sides of the bottom of a magnetic core material blank. Background Technology

[0002] Magnetic core material blanks are formed through magnetic powder die casting. During the die casting process, due to the mold's joints, burrs inevitably form on the bottom edge of the blank, which need to be removed. This is typically done with a vertically downward brush. However, because the sides of the magnetic core material blank are concave, when brushing its edges, the brush bristles are bent outwards by the edges, making it difficult for the bristles to reach the burrs on the concave sides. This results in a low burr removal rate on the sides of the blank, affecting its subsequent normal use. Utility Model Content

[0003] To address the aforementioned technical deficiencies, this invention provides a deburring device for the four sides of the bottom of a magnetic core material blank, which has a high burr removal rate and high deburring efficiency around the perimeter of the magnetic core material blank.

[0004] This utility model discloses a deburring device for the bottom four sides of a magnetic core material green blank, including a frame, a support plate on the frame, rollers at both ends of the support plate, a conveyor belt wound around the rollers, a first motor fixed on one end of the support plate, the first motor being connected to the rollers via transmission; the lower surface of the conveyor belt above the support plate is in contact with the support plate, a mounting frame is provided on one or both sides of the support plate, a second motor is provided on the mounting frame, a brush is fixed on the output shaft of the second motor, at least one brush is vertically downward and covers the magnetic core material green blank in the width direction of the conveyor belt, at least one brush forms an angle with the vertical plane and contacts the side wall of the magnetic core material green blank on one side in the width direction of the conveyor belt, at least one brush forms an angle with the vertical plane and contacts the side wall of the magnetic core material green blank on the other side in the width direction of the conveyor belt.

[0005] The angle between the brush in contact with the side wall of the green core material and the vertical plane in which the green core material is conveyed is 15-90°.

[0006] The angle between the brush in contact with the sidewall of the green core material and the vertical plane perpendicular to the conveying direction of the green core material is 15-75°.

[0007] The upper surface of the support plate has a series of mounting holes at intervals, and magnets are embedded in the mounting holes.

[0008] Mounting rods are provided on both sides of the support plate, and baffles are fixed on the mounting rods. The baffles extend to the upper surface of the conveyor belt, and a channel for conveying the green core material is formed between the two baffles.

[0009] The present invention provides a deburring device for the four sides of the bottom of a magnetic core material blank. It uses vertical and inclined brushes to deburr the two ends and two sides of the magnetic core material blank. The magnetic core material blank can remove burrs around its perimeter during the conveyor belt process, which is highly efficient and has a high burr removal rate.

[0010] After the burrs are removed, the sintered green core material has a more perfect appearance and feel, and is less likely to damage the tape when wrapping the transformer. Attached Figure Description

[0016] 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.

[0017] Example 1:

[0018] like Figures 1-5 As shown, this utility model discloses a deburring device for the bottom four sides of a magnetic core material green blank, including a frame 1, a support plate 2 on the frame 1, and rollers 5 at both ends of the support plate 2. A conveyor belt 3 is wound around the rollers 5. A first motor 6 is fixed on one end of the support plate 2, and the first motor 6 is connected to the rollers 5 for transmission. The lower surface of the conveyor belt 3 above the support plate 2 is in contact with the support plate 2. Mounting frames 7 are provided on both sides of the support plate 2, and a second motor 8 is provided on the mounting frames 7. A brush 9 is fixed on the output shaft of the second motor 8. At least one brush 9 is vertically downward and covers the magnetic core material green blank 4 in the width direction of the conveyor belt 3. At least one brush 9 forms an angle with the vertical plane and contacts the side wall of the magnetic core material green blank 4 on one side of the width direction of the conveyor belt 3. At least one brush 9 forms an angle with the vertical plane and contacts the side wall of the magnetic core material green blank 4 on the other side of the width direction of the conveyor belt 3.

[0019] The support plate 2 on the frame 1 is fixed and can be horizontal or inclined. Rotary rollers 5 are rotatably mounted at both ends of the support plate 2. A first motor 6 drives the rollers 5 to rotate, and the conveyor belt 3 is wound around the rollers 5 and driven by them to rotate, thus conveying the green core material 4. The support plate 2 supports the conveyor belt 3, and the conveyor belt 3 above the support plate 2 is in contact with it. During conveying, the conveyor belt 3 remains stable, ensuring stable conveying of the green core material 4. A second motor 8 is mounted on the mounting frame 7 on the support plate 2, and a brush 9 is mounted on the second motor 8. Whether the mounting frame 7 is located on one or both sides of the support plate 2 depends on actual needs and the shape of the mounting frame 7, and is not specifically limited. Under normal circumstances, during the conveying of the green core material 4, the concave sides of the green core material 4 are located on the sides in the conveying direction, i.e., on both sides of the width of the conveyor belt 3. In this embodiment, vertically downward brushes 9 are provided on two mounting brackets 7 at intervals. Brushes 9 inclined from the outside to the inside are provided on both sides of the green core material 4. There is an angle between the inclined brushes 9 and the side wall of the green core material 4 on the same side. During the conveying of the green core material 4, the brushes 9 can contact the green core material 4 and will not be squeezed by the edge of the green core material 4, causing the brush bristles to bend.

[0020] The arrangement of the vertically downward-pointing brush 9 and the inclined brush 9 can be selected according to actual needs and is not specifically limited. In this embodiment, it is preferred to arrange one vertically downward-pointing brush 9 first, then two inclined brushes 9 on both sides, and finally another vertically downward-pointing brush 9. The inclined brush 9 is arranged between the vertically downward-pointing brushes 9.

[0021] Specifically, during the deburring process, as the green core material 4 is being transported, the vertically downward-facing brush 9 rotates. When the end of the green core material 4 approaches the brush 9, the brush 9 is not obstructed, thus removing the burrs at the end of the green core material 4. When the green core material 4 moves away from below the vertically downward-facing brush 9, a portion of the brush 9 moves away from the green core material 4 first. During this rotation, the portion of the brush 9 moves vertically downwards to remove the burrs at the other end of the green core material 4. Therefore, the vertically downward-facing brush 9 can remove the burrs at both ends of the green core material 4 with a high removal rate. For the burrs in the concave areas on both sides of the green core material 4, inclined brushes 9 are used for removal. Since the lower ends of the brushes 9 are inclined towards the sides of the green core material 4, some brushes 9 are not obstructed by the upper sidewall of the green core material 4 during rotation, thus preventing bending. These brushes 9 can directly act on the burrs on the sidewall of the green core material 4, effectively removing them. This allows for deburring of the entire green core material 4, including the burrs in the concave areas on both sides, resulting in a high overall burr removal rate and efficiency.

[0022] The angle between the brush 9, which contacts the sidewall of the green magnetic core material 4, and the vertical plane in which the green magnetic core material 4 is conveyed is 15-90°. In this embodiment, 45° is preferred, but other angle values ​​such as 15°, 30°, 40°, 50°, 60°, 70°, 80°, and 90° can also be used. This angle setting allows the bristles of the brush 9 to directly contact the sidewall of the green magnetic core material 4 without bending, resulting in better deburring of the green magnetic core material 4.

[0023] The angle between the brush 9, which contacts the sidewall of the green magnetic core material 4, and the vertical plane perpendicular to the conveying direction of the green magnetic core material 4 is 15-75°. During the rotation of the brush 9, the relative movement between the bristles on both sides of the center of the brush 9 and the sidewall of the green magnetic core material 4 is opposite; that is, the bristles on one side pass from top to bottom along the sidewall of the green magnetic core material 4, while the bristles on the other side pass from bottom to top. As the green magnetic core material 4 moves on the conveyor belt 3, it will move from one side of the brush 9 to the other. This inevitably results in the bristles in contact with the green magnetic core material 4 moving upwards greater than those moving downwards. At this point, the entire brush will exert an upward pulling force on the green magnetic core material 4, causing the green magnetic core material 4 to flip, which is extremely detrimental to deburring production. Therefore, the brush 9, which contacts the side wall of the green core material 4, forms an angle of 15-75° with the vertical plane perpendicular to the conveying direction of the green core material 4. Whether the brush 9 is tilted forward or backward in the conveying direction of the green core material 4 depends on the rotation direction of the second motor 8 of the brush 9. That is, the bristles of the brush 9 that are in contact with the green core material 4 always move from top to bottom, while the bristles that move from bottom to top create a gap between the brush 9 and the green core material 4. This ensures that the green core material 4 will not be flipped during the movement of the side brush 9, thus improving the stability of the deburring process.

[0024] Mounting holes are arranged in a spaced array on the upper surface of the support plate 2, and magnets 12 are embedded in the mounting holes. When the green core material 4 is conveyed on the conveyor belt 3, the magnets 12 embedded on the support plate 2 can keep it on the conveyor belt 3, so that when the brush 9 deburrs it, it is less likely to cause relative displacement on the conveyor belt 3, thus affecting the deburring effect.

[0025] Mounting rods 10 are provided on both sides of the support plate 2, and baffles 11 are fixed on the mounting rods 10. The baffles 11 extend to the upper surface of the conveyor belt 3, and a channel for conveying the green core material 4 is formed between the two baffles 11. The baffles 11 are set on the conveyor belt 3, and there is a small gap between the baffles 11 and the conveyor belt 3. The two baffles 11 can effectively restrict the position of the green core material 4 on the conveyor belt 3, further improving its conveying stability on the conveyor belt 3 and improving the deburring effect. Under normal circumstances, the green core material 4 faces the conveyor belt 3, and the burrs are generally located on the side wall of the green core material 4 near the back, that is, the distance between the burr position and the conveyor belt 3 is 1-3cm. The distance between the upper end face of the baffle 11 and the conveyor belt 3 can be 0.5-1cm, so that it will not interfere with the burrs and will not affect the removal of burrs by the brush 9.
