Description

Technical Field

[0001] The utility model relates to the technical field of industrial brushes, and more specifically, to a steel wire brush core and a steel wire brush. Background Art

[0002] In industrial processing, the number of steel wire strands bundled in the brush core has an important impact on the performance of the steel wire brush. Steel wire brushes are usually used for surface treatment, cleaning, and grinding work, and their effects are directly affected by the number of steel wire strands in the brush core. The more the number of steel wire strands, the greater the diameter and circumference of the brush core, which results in the brush head being able to contact a larger area of the object surface during use.

[0003] Increasing the number of steel wire strands not only increases the contact area of the brush head but also improves the grinding efficiency. This is because when each brush head rotates, it covers a wider area, the processing speed is faster, and the grinding operation is more efficient. However, as the diameter of the brush core increases, the length of a single bundle of steel wires decreases accordingly, which may affect the service life and grinding ratio of the steel wire brush.

[0004] Currently, in order to meet the needs of industrial processing and improve the performance and efficiency of steel wire brushes, some new design strategies are being studied and applied. These strategies aim to maintain the structural stability and appropriate outer diameter of the brush core as much as possible while increasing the number of steel wire strands, so as to achieve a longer service life and higher grinding effect. Summary of the Invention

[0005] The utility model aims to solve one of the technical problems in the related technologies to a certain extent. For this reason, the utility model provides a steel wire brush core, which realizes the radial staggered connection of the first brush wire and the second brush wire by adding a second through hole, thereby improving the grinding ratio of the steel wire brush and extending the service life.

[0006] The utility model also provides a steel wire brush applying the above steel wire brush core.

[0007] The technical solution adopted by the utility model is as follows: A steel wire brush core is provided, which includes a disk body. The disk body has a circle of first through holes distributed at equal intervals in a ring shape and a circle of second through holes distributed at equal intervals in a ring shape. The first through holes and the second through holes are radially staggered and circumferentially spaced apart from each other. The first through holes are used to connect the first brush wires, and the second through holes are used to connect the second brush wires.

[0008] After adopting the above structure, the brush core of the wire brush can more effectively increase the number of wire strands while maintaining a stable structure and a suitable outer diameter. Through the first through holes and the second through holes annularly distributed on the disc body, the first brush wires and the second brush wires can be radially cross-connected to form a tighter brush core structure. This design strategy aims to improve the performance and efficiency of the wire brush, while extending the service life and enhancing the grinding effect. Among them, the grinding ratio of the wire brush can be increased by at least 20%, and the service life can be increased by at least 50%.

[0009] According to an embodiment of the present invention, the free ends of the first brush wires are flush with the free ends of the second brush wires; the free ends of the first brush wires and the second brush wires together form the working surface of the wire brush, and this working surface is used for descaling, cutting, grinding, deburring, sanding, polishing and buffing objects, components, surfaces, etc.

[0010] According to an embodiment of the present invention, the first through hole is a circular hole or an oval hole.

[0011] According to an embodiment of the present invention, the second through hole is a circular hole or an oval hole; the oval hole can accommodate more brush wires in the gap between two adjacent first through holes.

[0012] According to an embodiment of the present invention, a connection hole is provided at the center of the disc body.

[0025] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model. Embodiment 1

[0026] As Figure 1-2 shown, in this embodiment, a wire brush core is disclosed, which includes a disk body 1. The disk body 1 has a circle of equally spaced annularly distributed first through holes 11 and a circle of equally spaced annularly distributed second through holes 12. The first through holes 11 and the second through holes 12 are radially staggered and circumferentially spaced apart from each other. The first through holes 11 are used to connect the first brush filaments 2, and the second through holes 12 are used to connect the second brush filaments 3.

[0027] Furthermore, as combined with Figure 1 shown, in this embodiment, the disk body 1 is circular, and a connection hole 13 is provided at its center. The connection hole 13 is a hexagonal hole. A circle of equally spaced annularly distributed first through holes 11 and a circle of equally spaced annularly distributed second through holes 12 are provided on the disk body 1. The number of both the first through holes 11 and the second through holes 12 is 28, and the radius of the circle formed by connecting the centers of all the first through holes 11 is greater than the radius of the circle formed by connecting the centers of all the second through holes 12, that is, the first through holes 11 are located outside the second through holes 12. The first through holes 11 and the second through holes 12 are circumferentially spaced apart, that is, each second through hole 12 is located between two adjacent first through holes 11, or in other words, a second through hole 12 is distributed on the perpendicular bisector of the line connecting the centers of two adjacent first through holes 11. The first through holes 11 are circular holes, and the second through holes 12 are waist-shaped holes.

[0028] In some other embodiments, the first through hole 11 and the second through hole are both circular holes, or the first through hole 11 and the second through hole 12 are both kidney-shaped holes.

[0029] Specifically, the free end of the first brush wire 2 is flush with the free end of the second brush; the free ends of the first brush wire 2 and the second brush wire 3 form the working surface of the wire brush, and this working surface is used for descaling, cutting, grinding, deburring, sanding, polishing, and buffing objects, components, surfaces, etc. Embodiment 2

[0030] Combined Figure 3-4 As shown, in this embodiment, a wire brush is disclosed, which includes a first brush wire 2, a second brush wire 3, and the wire brush core described in Embodiment 1.

[0031] Specifically, the wire brush further includes an upper gasket 4, a lower gasket 5, and a rivet 6. The upper gasket 4, the brush core, and the lower gasket 5 are stacked in sequence from top to bottom. The rivet 6 presses and fixes the upper gasket 4, the brush core, and the lower gasket 5 tightly together.

[0032] Furthermore, in this embodiment, hexagon holes are provided at the centers of the upper gasket 4 and the lower gasket 5. When the upper gasket 4, the brush core, and the lower gasket 5 are stacked from top to bottom, the hexagon holes on the upper gasket 4 and the lower gasket 5 are aligned with the connection hole 13 of the brush core and form a hexagonal channel. Then, the rivet 6 has a hollow hexagonal column structure adapted to the hexagonal channel. This hexagonal column structure passes through the hexagonal through hole and is flanged and deformed to axially press the upper gasket 4, the brush core, and the lower gasket 5. The upper gasket 4 and the lower gasket 5 tightly press and fix the first brush wire 2 and the second brush wire 3 therebetween, preventing the first brush wire 2 from deflecting around the first through hole 11 and preventing the second brush wire 3 from deflecting around the second through hole 12.

[0033] Furthermore, the wire brush further includes a rotary power tool (not shown in the figure), and the rotary power tool is detachably connected to the rivet 6.
