Electroplated steel wire segment-combined grinding wheel

An electroplated steel wire segment-combined grinding wheel, comprising:

• a base component for connecting an external device, and
• a plurality of steel wire segments,
• wherein the plurality of steel wire segments are combined and assembled on the base component in a ring, and outer walls of the plurality of steel wire segments are plated with diamonds to form a grinding surface, further comprising
• a first support ring for supporting the plurality of steel wire segments, and a fixing part for fixing the first support ring, wherein
• the base component comprises a first base;
• the fixing part is disposed opposite to the first base, and the first support ring is held between the fixing part and the first base;
• the plurality of steel wire segments are arranged on an outer wall of the first support ring;
• the first base is of a circular disc structure, the fixing part comprises a first pressure plate of an annular disc structure, and the first support ring has an annular groove structure;
• the first pressure plate is disposed coaxially opposite to the first base;
• a groove bottom of the first support ring is disposed outward and parallel to a central axis of the first base, a groove opening of the first support ring is disposed inward, a first end of the groove opening of the first support ring is abutted against an outer edge of the first base, and a second end of the groove opening of the first support ring is abutted against an outer edge of the first pressure plate;
• a cavity is formed among the first base, the first support ring and the first pressure plate;
• each of the plurality of steel wire segments is bent to have a U shape and bonded to an outer wall of the groove bottom of the first support ring, a first end of each of the plurality of steel wire segments is clamped into a slit between the first base and the first end of the groove opening of the first support ring, a second end of each of the plurality of steel wire segments is clamped into a slit between the first pressure plate and the second end of the groove opening of the first support ring, and the plurality of steel wire segments are arranged circumferentially in parallel;
• the first base is recessed axially in the ring in proximity to an end face of the first pressure plate and at the outer edge of the first pressure plate to form a first annular step;
• the first pressure plate is protruded axially in the ring in proximity to both an end face and an inner edge of the first base to form an annular protrusion, and a second annular step is formed in proximity to the outer edge of the first pressure plate;
• the first end and the second end of the groove opening of the first support ring are abutted against the first annular step and the second annular step respectively, a first end of an outer side of the groove bottom of the first support ring extends out of the outer edge of the first pressure plate, and a second end of the outer side of the groove bottom of the first support ring extends out of the outer edge of the first base;
• a plurality of hemispherical protruding points is disposed on a surface of each of the plurality of steel wire segments in contact with the first annular step and the second annular step;
• the plurality of hemispherical protruding points are disposed in parallel in a radial direction of the first base or the first pressure plate;
• each of the first annular step and the second annular step is provided with hemispherical grooves corresponding to the plurality of hemispherical protruding points respectively;
• and
• the plurality of hemispherical protruding points on the plurality of steel wire segments are clamped into corresponding hemispherical grooves, respectively.
