Abstract

The invention relates to an all-powder ultrathin diamond saw blade, which comprises the following matrix elements in percentage by mass: 45 to 65 percent of Cu, 8 to 12 percent of Sn, 8 to 12 percent of Co, 2 to 4 percent of Ni, 2 to 4 percent of Ag, 0.3 to 0.5 percent of S, 0.2 to 0.3 percent of P, 0.2 to 0.3 percent of C, and the balance of Fe. Based on 100 percent of concentration of standard 0.88g/cm<3> diamond, the diamond concentration is 16 to 28 percent. By the technical scheme, the all-powder ultrathin diamond saw blade has the advantages that: 1, there is no matrix, and matrix waste is greatly reduced; 2, the thickness can reach 0.3 to 0.6mm; and 3, the height of a tool bit is 30 percent of the outer diameter of the saw blade, the service life of the product is long, the cutting efficiency is high, and a sawn joint is small.

Description

A kind of full powder slim diamond blade

Technical field

The present invention relates to a kind of diamond saw blade, especially a kind of full powder slim diamond blade.Belong to metallurgical technology field.

Background technology

Existing carrier matrix saw blade, the centre is generally 65Mn material steel disc matrix, after cutter head uses, the steel disc matrix can not be reused, cause the steel waste, conventional steel disc matrix accounts for the 10%-15% of whole saw blade material cost, and noise cancelling type steel disc matrix and the shared cost of sandwich type steel disc matrix compare Lie Genggao.

The quality restriction of steel, it is too thin to make that conventional steel matrix saw blade thickness can not be done.In general, the saw blade of external diameter Φ 100mm specification, matrix thickness 0.8mm, cutter head 1.0mm reaches capacity.Because saw blade thickness height so kerf width reaches 1.0mm, makes that the loss that is cut material is big, it is serious to be cut waste of material.

Summary of the invention

The objective of the invention is: at above reality, propose a kind of full powder slim diamond blade, the full powder once-forming of no matrix, its thickness are that thickness is 0.3-0.6mm.Long service life, the cutting efficiency height.

Based on above purpose, the present invention takes following technical scheme to realize: a kind of full powder slim diamond blade, and its matrix element is formed and the mass percent prescription is: Cu, 45-65%; Sn, 8-12%; Co, 8-12%; Ni, 2-4%; Ag, 2-4%; S, 0.3-0.5%; P, 0.2-0.3%; C, 0.2-0.3%, all the other are Fe, by standard diamond content 0.88 gram/cm ³Be 100% densimeter, diamond concentration is 16-28%.

Because the present invention adopted above technical scheme, the present invention has the following advantages: the one, and no matrix has significantly reduced the waste of matrix; The 2nd, its thickness can reach 0.3-0.6mm; The 3rd, the cutter head height reaches 30% of saw blade external diameter, long product lifecycle, and the cutting efficiency height, saw kerf is little.

The specific embodiment

The invention will be further described below in conjunction with embodiment.

Embodiment one

A kind of full powder slim diamond blade, its matrix element is formed and the mass percent prescription is: Cu, 45%; Sn, 12%; Co, 10%; Ni, 2%; Ag, 3%; S, 0.3%; P, 0.2%; C, 0.2%, all the other are Fe, by standard diamond content 0.88 gram/cm ³Be 100% densimeter, diamond concentration is 16%.

The manufacture craft of aforesaid full powder slim diamond blade may further comprise the steps:

A), get the raw materials ready---by component design required raw and auxiliary materials such as matrix element and diamond are prepared;

B), mix---the mixed powder and the diamond that will be poured on together stirs, and sieves with screen cloth, pours in the batch mixer and mixes having crossed the powder that sieves, and after the shutdown, sieves with screen cloth again, with the steel spoon powder is taken off flat, estimate and check errorless after, enter next operation;

C), dress mould precompressed---powder that will be mixed detects apparent density, calculates powder according to apparent density and adorns the required height of mould, and powder is packed in the mould, carries out precompressed;

D), hot pressed sintering---mould of precompressed is put into vacuum sintering furnace, hot pressed sintering;

E), smooth---with burned saw blade sand papering, remove burr, separate layer by layer with smooth smooth high purity graphite piece and to put into the bell jar stove, feed the protection gas shiled, come out of the stove behind the heat tracing, continue to feed the protection gas shiled, equitemperature is reduced to room temperature, close protection gas, open cover body, take out saw blade;

F), fraising, shaping---according to product requirement, select suitable carbide-tipped reamer for use, the hole is remedied to correct diameter, measure saw blade thickness, with twin grinder saw blade is ground to required thickness;

G), put the first edge on a knife or a pair of scissors---saw blade is contained on the blade grinding machine puts the first edge on a knife or a pair of scissors;

H), printing package sprays paint---the saw blade surface is sprayed the paint of one deck required color, lettering, packing then uniformly.

The present invention has the following advantages: the one, and no matrix has significantly reduced the waste of matrix; The 2nd, its thickness can reach 0.3-0.6mm; The 3rd, the cutter head height reaches 30% of saw blade external diameter, long product lifecycle, and the cutting efficiency height, saw kerf is little.

Embodiment two

With a kind of full powder slim diamond blade of embodiment one, its matrix element is formed and the mass percent prescription is: Cu, 55%; Sn, 10%; Co, 12%; Ni, 3%; Ag, 4%; S, 0.4%; P, 0.25%; C, 0.3%, all the other are Fe, by standard diamond content 0.88 gram/cm ³Be 100% densimeter, diamond concentration is 22%.

Embodiment three

With a kind of full powder slim diamond blade of embodiment one, its matrix element is formed and the mass percent prescription is: Cu, 60%; Sn, 8%; Co, 8%; Ni, 4%; Ag, 2%; S, 0.5%; P, 0.3%; C, 0.25%, all the other are Fe, by standard diamond content 0.88 gram/cm ³Be 100% densimeter, diamond concentration is 28%.

In addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.

Claims

1. full powder slim diamond blade, its matrix element is formed and the mass percent prescription is: Cu, 45-65%; Sn, 8-12%; Co, 8-12%; Ni, 2-4%; Ag, 2-4%; S, 0.3-0.5%; P, 0.2-0.3%; C, 0.2-0.3%, all the other are Fe, by standard diamond content 0.88 gram/cm ³Be 100% densimeter, diamond concentration is 16-28%.
