Problems solved by technology

[0003] The structure of diamond beaded wire saw is as follows figure 1 and figure 2 As shown, it is composed of beads 1, steel rope 2 and fixed sleeve 3. Beads 1 is composed of carcass working layer 11 and lining body 12. The material of lining body is generally made of steel or copper. The processing process includes turning, drilling , milling and other cumbersome processes, the lining body needs to be tapped after beading sintering, resulting in a high comprehensive processing cost of the lining body (about 0.3-0.5 yuan / piece)
At the same time, compared with the diamond in the working layer of the carcass, the lining is a soft material, and its wear resistance is poor
[0004] When using a wire saw to cut reinforced concrete, since the cutting area of ​​a single concrete beam is relatively small, generally 0.5m 2 Below, it is different from large-scale cutting of stone (generally 20m 2 Above), it is basically impossible to install auxiliary guide wheels, so that the cutting track envelope of the wire saw is very small, and the front end of the working layer of the beaded carcass is vulnerable to impact and wear; in addition, the length of the wire saw used for the small cutting surface is relatively short , the rotation of the wire saw is not smooth, and it is easy to produce eccentric wear of the wire saw beads
Because the material of the lining body is relatively soft and not wear-resistant, once the working layer of the carcass is partially worn, the lining body will rub against the reinforced concrete, the beaded lining body and the steel rope will wear out quickly, and eventually the wire saw will break
Through the analysis of the actual use of the wire saw, its service life is basically only 50-62% of the design life, resulting in a great waste of raw materials, and also increases the use cost of the wire saw in disguise

Abstract

The invention relates to a wire saw bead string and a manufacturing method thereof. The wire saw bead string comprises a carcass working layer and a liner, and is mainly characterized in that the liner is formed by sintering iron-copper alloy powder and a small amount of small-size diamond, and then integrating the sintered product and the carcass working layer in a hot pressed sintering manner. In addition, in order to fix the wire saw bead string on a steel wire rope, concave and convex structures are respectively arranged on the inner side and ends of the liner. Compared with a common wire saw bead string in existing markets, the wire saw bead string has the advantages that the wear resistance of the liner of the wire saw bead string is high, and an auxiliary cutting function is fulfilled. On the one hand, the circumstances that the carcass working layer of the bead string is consumed unevenly in the radial direction or the axial direction, the liner and a steel rope will be abraded soon, the carcass working layer is not consumed completely, and a cutting material is wasted can be avoided; and on the other hand, a manufacturing process of the liner of the wire saw bead string is simple and convenient, the production efficiency is high, and the comprehensive cost is low. The wire saw bead string has quite high practical value and technical advantages.
