Abstract

The invention relates to the field of diamond rope saw bead strings, in particular to a preparation method of a diamond rope saw bead string based on metal powder extrusion molding. The preparation method of the diamond rope saw bead string based on metal powder extrusion molding comprises the following steps of A, performing dry mixing on metal pre-alloy powder and diamond particles, and heatingand kneading matrix alloy powder and a high-viscosity water-based binder; B, extruding and molding the matrix alloy extrusion feed into a matrix alloy round tube; C, cutting the matrix alloy round tube into a circular ring blank; and D, carrying out dip soaking water solvent degreasing and drying treatment on the diamond bead string ring blank. By means of the preparation method of the diamond rope saw bead string based on metal powder extrusion molding, a diamond rope saw bead string with uniformly-distributed diamond particles in an alloy matrix is prepared, the cutting speed of a diamond rope saw is improved, and the service life is prolonged.

Description

technical field

[0001] The invention relates to the field of diamond wire saw beads, in particular to a method for preparing diamond wire saw beads based on metal powder extrusion molding. Background technique

[0002] The diamond wire saw is made of cylindrical diamond wire saw beads strung on the wire rope, and then each diamond wire saw bead is fixed through a rubber-plastic spacer to form a complete diamond wire saw, in which the cylindrical diamond wire saw beaded It is composed of a cylindrical iron core support body and a diamond alloy matrix containing diamond particles on the periphery of the core body. However, the existing diamond wire saw beading injection molding beading process has the phenomenon that the matrix alloy and diamond particles are unevenly distributed due to the retardation effect of the injection mold runner and the cavity gate on the diamond particles, which seriously affects the cutting speed and cutting speed of the diamond wire saw. Problems ...
