Embodiment 1

[0030] Example 1, GR115 type sintered wire saw beads, the height of the steel body 3 is 11mm, the outer diameter is 7.5mm, the height of the metal carcass 2 is 6mm, the outer diameter is 11.5mm, and the inner diameter is equal to the outer diameter of the steel body. The metal spacers do not contain diamonds in three circles, which are continuously distributed in the metal matrix 2 in a helical shape. The thickness of the metal spacer is 0.5 mm, the outer diameter of 11.44 mm is smaller than the outer diameter of the metal carcass 2 of 0.06 mm, and the inner diameter of 7.7 mm is larger than the outer diameter of the steel body 3 of 0.2 mm.

[0031] How it's made:

[0032] a. Choose hot-rolled copper square wire with a thickness of 0.5mm and a width of 1.87mm. Through a spring winding machine, it is wound into a spring-like spiral metal spacer, and the two ends are ground, and the outer diameter is the same as that of the metal tire. The outer diameter is equal, the number of...

Abstract

The invention discloses a sintered rope saw string bead. The sintered rope saw string bead consists of diamond, a metal mold, a steel body and metal separation bars; the hardness of the metal separation bars is lower than the hardness of the metal mold; the metal separation bars are continuously distributed in the metal mold; the diamond is distributed in the metal mold; and the metal mold is fixedly connected to the surface of the steel body. Based on a traditional sintered rope saw string bead, the low-hardness spiral metal separation bars are implanted in the metal mold; when a rope saw works, the spiral metal separation bars without the diamond are easily rubbed and scoured by cutting chips to form spiral grooves on the surface of the string bead; and the grooves can achieve the effects of reinforced diamond cooling and smooth chip removal in the cutting process, so that the cutting efficiency of the rope saw is improved.

Description

technical field [0001] The invention relates to the field of wire saws, in particular to beads for wire saws. Background technique [0002] Wire saws can be used for stone mining, block shaping, stone factory plate processing, reinforced concrete engineering cutting, and metal component cutting. With the advancement of wire saw technology, efficient cutting has become a major focus of development in this field. In recent years, single-layer diamond wire saws such as electroplating and brazing have been gradually developed. The gap between the abrasive grains on the surface is large, so that the space for chips on the beaded surface is large, the diamond has a high cutting edge, and the cutting efficiency is high; but it has only a single layer of abrasive grains, and the life is short. Can't meet demand. Sintered wire saw beads, such as figure 1 , 2 As shown, it is embedded in the metal matrix 2 by diamond 1 and fixed on the steel body 3. Usually, the three are fixed tog...
