Description
The technical field is as follows:
the invention relates to a brazed diamond bead stringing saw without an isolation sleeve, and belongs to the technical field of wire saws.
Background art:
the diamond bead saw consists of a steel wire rope core, diamond beads and an isolating sleeve, wherein the beads are strung on the rope core at certain intervals and are separated by the isolating sleeve. The diamond bead stringing saw has the advantages of high cutting efficiency, good sawing quality, flexible use and the like, and is widely applied to the aspects of stone mining, stone shaping processing, special-shaped stone processing, concrete cutting and the like.
The preparation method of the bead mainly comprises 3 methods: sintering, electroplating, and brazing. The sintering method is based on the principle of powder metallurgy, and is characterized in that diamond and selected matrix powder are uniformly mixed or granulated and then combined with a matrix for sintering. The bead string is manufactured by the electroplating method, the manufacturing process is relatively simple, and the diameter reduction of the bead string is more facilitated. However, the plating layer to which the diamond abrasive grains are fixed by the electroplating method is too thin, and the holding force of the plating layer to the diamond abrasive grains is limited, and the diamond abrasive grains are likely to be dropped off at an early stage. The principle of the brazing method is that the brazing filler metal generates holding force on diamond by means of the interaction of melting, infiltration, diffusion, combination and the like generated on the interfaces of the abrasive, the brazing filler metal and a substrate during brazing. The method has the advantages of high bonding strength between the diamond and the matrix, long service life, large cutting edge height of diamond bead abrasive particles, large chip capacity, low grinding temperature and high cutting efficiency.
The isolation sleeve is positioned between adjacent beads on the wire rope core of the bead saw and supported on the opposite end surfaces of the two beads, so that the axial relative positions of the beads on the wire rope core are ensured. There are three types of spacer sleeves: spring washer, injection molded, and rubber injected.
The mode of fixing the beads by the isolating sleeve has a certain gap between the beads and the wire rope core, and the beads are easy to have the defects of rotation, play, displacement and the like. The string of beads saw drives string of beads axial displacement under the effect of axial cutting force at the course of the work, and then extrudes the spacer sleeve to lead to the spacer sleeve to be compressed and take place elastic deformation. When the axial force is large enough, the port of the isolation sleeve, especially the front port, is easily enlarged, and the port part of the isolation sleeve is damaged. Especially for the isolating sleeve made by rubber injection, the front end of the bead string is easy to be inserted into the expanded port of the rubber isolating sleeve, so that the bead string moves on the steel wire rope core, the whole bead string saw is scrapped, and the working efficiency and the service life of the diamond bead string saw are seriously influenced. In addition, in the process of cutting the sharp corner of the workpiece, the isolating sleeve of the bead saw is easily damaged by cutting materials, so that adjacent beads are tightly abutted, the bead saw is clamped in a saw slot and cannot cut, and even the bead saw is broken. Therefore, the invention provides a bead string saw without an isolation sleeve, which completely prevents beads from moving on a steel wire rope core, and is a problem to be solved urgently in the technical field of bead string saw cutting.
The invention content is as follows:
in view of the above-mentioned prior art defects, the present invention provides a brazed diamond bead saw without an isolation sleeve, which solves the problem of the damage of the isolation sleeve between adjacent beads of the existing diamond bead saw, thereby avoiding the failure of the bead saw caused by the damage of the isolation sleeve.
In order to achieve the purpose, the invention adopts the technical scheme that: a braze welding diamond bead without an isolation sleeve comprises a plurality of steel wire rope cores and a metal base body, wherein the metal base body is in a cylindrical sleeve shape, a plurality of through holes are formed in the cylindrical surface, the metal base body is provided with a central hole for the steel wire rope cores to pass through, and the metal base body is uniformly stringed on the steel wire rope cores at intervals; and diamond particles which are solidified through brazing filler metal in a brazing mode are arranged on the outer cylindrical surface of the metal base body, and the brazing filler metal is also distributed in the through holes of the cylindrical surface of the metal base body and is brazed on the steel wire rope core.
Further, the steel wire rope core is made of austenitic stainless steel, and the diameter of the steel wire rope core is 1.0-10 mm;
further, the metal matrix is made of magnetic conductive materials containing iron, nickel and the like, the diameter of a center hole of the metal matrix is slightly larger than that of the steel wire rope core, and preferably, the outer diameter of the metal matrix is 2-15 mm;
furthermore, the diameter of a plurality of through holes formed in the cylindrical surface of the metal base body is 0.3-3.0 mm, when the diameter of the steel wire rope core is small, the small value is taken, and when the diameter of the steel wire rope core is large, the large value is taken;
further, the distance between adjacent metal substrates on the steel wire rope is 5-30 mm, when the diameter of the steel wire rope core is small, the value is small, and when the diameter of the steel wire rope core is large, the value is large;
further, the brazing filler metal is Ni-Cr alloy brazing filler metal;
furthermore, the brazing mode adopts high-frequency induction brazing, because the steel wire rope core made of austenitic stainless steel is not magnetic-conductive, current cannot be generated in the induction coil of the high-frequency induction machine, and the metal matrix is made of magnetic-conductive materials containing iron, nickel and the like, current can be generated in the induction coil of the high-frequency induction machine, so that the metal matrix can generate high temperature under the magnetic field of the high-frequency induction coil, and brazing filler metal on the metal matrix is heated and melted; after the brazing filler metal is solidified, firmly brazing the diamond particles on the cylindrical surface of the metal matrix; in addition, the molten brazing filler metal can also enter a plurality of through holes with equal diameters formed in the cylindrical surface of the metal matrix and contact with the steel wire rope core, and after the brazing filler metal is solidified, the metal matrix and the steel wire rope core can be combined in a brazing mode, so that the metal matrix is prevented from moving and rotating on the steel wire rope core.
The invention has the advantages that: in the spacer sleeve-free brazed diamond bead, the cylindrical surface of the metal substrate is provided with a plurality of through holes, and brazing filler metal enters the through holes during brazing to firmly combine the metal substrate and the steel wire rope core, so that a spacer sleeve arranged between adjacent beads of the conventional bead saw is not needed, cutting interruption caused by damage of the spacer sleeve in the cutting process is avoided, the cutting efficiency is improved, and the service life of the bead saw is prolonged.
