DETAILED DESCRIPTION

[0026] The following is combined with Figure 1 -Attached Figure 9 The utility model is further described in detail:

[0027] The present invention discloses an improved black diamond grinding sheet. Figure 1 、 Figure 2 As shown, an improved black diamond grinding sheet of the present invention comprises a base wheel 1, a first pressure plate 2, a second pressure plate 3 and a connecting rod 4, and also comprises a cutting base wheel 5; one end of the connecting rod 4 is integrally formed with a connecting head 41 for connecting to a grinder, and the other end of the connecting rod 4 is integrally formed with a first pressure plate 2, and the base wheel 1 is fixedly connected to the first pressure plate 2 and the second pressure plate 3 by bolts; a four-wing conical protrusion 42 is provided on the outer wall of the connecting rod 4, and a four-wing conical groove 43 is provided on the inner wall of the cutting base wheel 5, and the four-wing conical protrusion 42 can be embedded in The four-winged conical groove 43 forms a detachable inlay fit, and the cutting base wheel 5 is fixedly connected to the base wheel 1 and the first pressure plate 2 by bolts. In this embodiment, by adding the cutting base wheel 5, the properties of the black diamond grinding sheet can be utilized to perform some simple cutting work. It is worth noting that the thickness of the cutting base wheel 5 is less than that of the base wheel 1. The thicker base wheel 1 is used for grinding, while the extremely thin cutting base wheel 5 can perform cutting work. This allows the present invention to perform both grinding with the base wheel 1 and cutting with the cutting base wheel 5. By providing the four-winged conical protrusion 42 and the four-winged conical groove 43, the connecting rod 4 and the cutting base wheel 5 can cooperate and lock with each other to prevent the connecting rod 4 and the cutting base wheel 5 from rotating relative to each other.

[0028] like Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 As shown, the base wheel 1 and the cutting base wheel 5 are composed of a plurality of polished surfaces, each of which includes a horizontal ring 12 and a vertical ring 13. The base wheel 1 and the cutting base wheel 5 are hot-pressed by a mold so that each of the polished surfaces inside them is formed with a plurality of quadrangular pyramidal concave and convex surfaces 11; in this embodiment, since it is an improvement on the utility model cited in the background technology, the base wheel 1 and the cutting base wheel 5 both include the structure in the prior art, that is, the structure of the base wheel 1 in the utility model patent with patent announcement number CN221517378U, that is, a plurality of horizontal rings 12 are arranged on the same horizontal plane and arranged in a horizontal and vertical array, such as Figure 6 、 Figure 7 As shown, the side walls of the horizontal rings 12 are fixedly connected to the side walls of other horizontal rings 12 on the same horizontal plane; a vertical ring 13 is fixedly connected between four adjacent horizontal rings 12, and there is a vertical relationship between two adjacent vertical rings 13, and each polishing surface is fixedly connected through the vertical ring 13.

[0029] On this basis, a special three-dimensional mold is added, a thermal press is added, and a three-dimensional mold pattern is used. After the force press, mold, temperature, time, and pressure are applied, a black diamond-shaped basic mesh with a three-dimensional pattern is integrated and produced. Preferably, the mold is a mold with a quadrangular pyramidal protrusion. Each polished surface is formed with a plurality of quadrangular pyramidal concave-convex surfaces 11 by mold hot pressing. Several polished surfaces are combined to form a mesh with a three-dimensional pattern. The mesh with the three-dimensional pattern is then processed further. After sandblasting and glue spraying, the basic mesh is further made into a base wheel 1 and a cutting base wheel 5 by cutting and other methods. The base wheel 1 and the cutting base wheel 5 maintain three-dimensionality, and have high sharpness and high storage capacity, thereby enhancing wear resistance. Without changing the excellent elasticity and air permeability of ordinary black diamond grinding sheets, the strength resistance, heat resistance, and wear resistance are improved, the grinding efficiency is improved, the cost is reduced, the efficiency is improved, and the labor, time, and effort are saved. Preferably, the base wheel 1 and the cutting base wheel 5 are both modified polyurethane materials.

The three bolts for fixing the cutting base wheel 5 respectively pass through the cutting base wheel 5, the second pressure plate 3, the base wheel 1 and the first pressure plate 2 to fixedly connect the cutting base wheel 5 with the base wheel 1 and the first pressure plate 2. At this time, the cutting base wheel 5 tightly covers the upper side of the base wheel 1.

[0031] As Figure 2 shown, the cross-sectional shape of the four-winged conical groove 43 on the inner side wall of the cutting base wheel 5 is a long trapezoid. The width of the long trapezoid near the bottom edge connecting to the connecting rod 4 is greater than the width of the opposite bottom edge. The four-winged conical protrusion 42 on the connecting rod 4 is correspondingly arranged with the four-winged conical groove 43 on the inner side wall of the cutting base wheel 5. In this embodiment, the number of the four-winged conical protrusions 42 and the four-winged conical grooves 43 is N, and N≥2. The cutting base wheel 5 is provided with N four-winged conical grooves 43, and they are evenly arranged on the inner side wall of the cutting base wheel 5, that is, the distance between every two four-winged conical protrusions 42 is the same.
