Background

A diamond string bead wire saw is a green tool for stone mining and processing, and mainly comprises diamond string beads, a steel wire rope and an injection molding layer. The diamond bead consists of a working layer and a substrate, wherein the working layer is in a common cylinder shape, diamond abrasive particles are filled on the surface and the inside of the working layer, mixed with metal or alloy powder and formed by consolidation on the substrate after cold pressing. The reasonable design of the appearance and the structure of the bead string is beneficial to prolonging the service life of the diamond wire saw.

The conventional diamond wire saw bead is in a straight cylinder shape and can be threaded on a steel wire rope. The bead matrix is generally made of steel or copper and is cylindrical, the processing process comprises the working procedures of turning, drilling, milling and the like, and after the solidification of the beads is finished, the holes in the matrix also need to be tapped, so that the comprehensive processing cost of the diamond beads is higher (about 0.3-0.5 yuan/piece); in addition, the diamond wire saw is a flexible cutting tool, a cutting object is tied by the guide wheel, the length of the straight-tube-shaped substrate is about 10-15 mm, and when a rope passes through the guide wheel or the object in the cutting process, the port of the rigid substrate and the steel wire rope generate stress, so that the steel wire rope is disconnected; in addition, in the injection molding process of the rope saw, the steel wire rope is possibly eccentric in the base hole, so that the port of the rigid base body is in direct contact with the steel wire rope, and the steel wire rope is broken in advance due to stress during cutting.
