Problems solved by technology

Diamond beads are composed of a metal core and diamond beads on it. Most of them are manufactured by electroplating inlay or graphite resistance heating and sintering. The holding force is limited, the diamond beads are easy to fall off the core body in advance, the coating layer is thin, and the service life is short; in the graphite resistance heating sintering method, the mold pressure head is thin and easily damaged, resulting in high production costs , and at the same time limited by the furnace cavity, each furnace can only sinter 30 to 40 pieces, and the production efficiency is low

Embodiment 1

[0026] 1 kg of Co, Sn, and Ni metal powders in a ratio of 80%: 5%: 15%;

[0027] Put the proportioning material into the GM130 three-dimensional mixer and dry mix for 90 minutes;

[0028] Add 42 grams of 40 / 50 particle size diamond and 100 ml of isopropanol with a concentration of 60% to mix with 100 ml of binder and wet mix for 60 minutes to make it uniform;

[0029] Put the mixed wet material into GA180 granulator for granulation;

[0030] Make bead body 1 by cold pressing forming, in the present embodiment, the external diameter of bead body 1 is 11 millimeters, and internal diameter is 8.5 millimeters, and blank length is 7.5 millimeters, and the selected steel mold has the quantity of molding die holes on it as 6 . Use a balance to divide the pellets into 6 parts (2.1 grams each), fill them into the 6 forming die holes one by one, vibrate the steel mold to make the pellets in each hole dense and even, and select a punching machine with six heads that matches the steel m...

Embodiment 2

[0037] With C0, Sn, Fe, Ni metal powder by 45%: 5%: 35%: 15% proportioning 1 kilogram;

[0038] Put the proportioning material into the GM130 three-dimensional mixer and dry mix for 90 minutes;

[0039] Add 36 grams of 40 / 50 grain size diamond and 100 ml of isopropanol with a concentration of 60% of the binder and wet mix for 60 minutes to make it uniform;

[0040] Put the mixed wet material into GA180 granulator for granulation;

Abstract

A diamond bead manufacture method belongs to the technical field of diamond bead used for solving the defects of poor reliability for the felting of a core body and a bead body, short service life and low manufacture efficiency in the existing manufacture method. The technical scheme includes the steps of dosing, dry mixing, adding diamond powder and adhesive wet mixing, particle manufacturing, manufacturing and assembling of the core body and the bead body as well as heating and sintering. A clearance for sleeve is reserved between the bead body and the core body. A welding wire ring is additionally sleeved on the externally revealed end of the core body and is heated and sintered to vacuum baking with a baking temperature of 830 to 1050 DEG C and a baking time of 30 t0 60 minutes; the welding wire ring after melted in the sintering process penetrates into the bead powder through the clearance between the bead body and the core body to realize the felting between the bead body and the core body; the invention has the advantages of good felting intensity, good reliability, difficult falling off from the core body of the bead body, long service life and the invention can improve the manufacture efficiency in large scale by selecting a vacuum furnace with big volume.

Description

technical field [0001] The invention relates to a manufacturing method of a wire saw, in particular to a manufacturing method of a diamond beaded rope, and belongs to the technical field of diamond beading. Background technique [0002] The diamond bead strings are worn at intervals and fixed on the wire rope to form the diamond string saws. Diamond beads are composed of a metal core and diamond beads on it. Most of them are manufactured by electroplating inlay or graphite resistance heating and sintering. The holding force is limited, the diamond beads are easy to fall off the core body in advance, the coating layer is thin, and the service life is short; in the graphite resistance heating sintering method, the mold pressure head is thin and easily damaged, resulting in high production costs , At the same time, due to the limitation of the furnace body cavity, each furnace can only sinter 30 to 40 pieces, and the production efficiency is low. To sum up, a more advanced ma...
