Abstract
The invention relates to a tool bit, in particular to a tool bit for cutting granite and a manufacturing technology of the tool bit. The tool bit is formed by metal powder and a diamond solution in a manufactured mode, the metal powder comprises, by weight, 40-50% of iron powder, 30-40% of copper powder, 5-10% of nickel powder, 5-10% of cobalt powder, 5-10% of tin powder and 5-10% of zinc powder, and the purity of every metal component is over 99.8%. The tool bit for the granite and a manufacturing method are provided, and the tool bit is hard, good in abrasion resistance and long in service life.
Description
Technical field
The present invention relates to a kind of cutter head, particularly a kind of cutter head of cutting granite and preparation technology thereof.
Background technology
Because granite product is widely used, the process velocity of granite product, precision, production efficiency depend on granite cutter head, and existing granite cutter head tyre body abrasion is too fast, intensity difference, and the life-span is low.For diamond and carcass poor bonding strength are provided, cause diamond from carcass, to come off too early, reduction of service life, reduced adamantine utilization rate.
Summary of the invention
The problems referred to above that exist in order to solve the cutter head of cutting granite, the object of this invention is to provide the hard wind and thunder of a kind of cutter head, and anti-wear performance is good, granite cutter head of long service life and preparation method thereof.
Solution of the present invention is:
A cutter head for cutting granite, is made by metal dust and diamond solution,, described metal dust is comprised of at more than 99.8 percentage by weights following purity:
Iron powder: 40～50%;
Copper powder: 30～40%;
Nickel powder: 5～10%;
Cobalt powder: 5～10%;
Glass putty: 5～10%;
Zinc powder: 5～10%;
The mass concentration of described diamond solution is 30～40%.
The preparation technology of the cutter head of cutting granite, comprises the steps:
(1) by above-mentioned part by weight, metal dust and diamond solution are taken;
(2) above-mentioned compound is placed 2～4 hours at normal temperatures and pressures;
(3) above-mentioned compound is put into mould, at 4000Kgf/cm
2the forming under the pressure of colding pressing, and keep the pressure semi-finished product of 3 seconds;
(4) by semi-finished product, at 700 degrees Celsius, be raised to 800 degrees Celsius of insulations 2 minutes, be then warmed up to 900 degrees Celsius, obtain semi-finished product after sintering;
(5) semi-finished product after sintering are polished, join sand;
(6) be packaged into finished product.
Owing to there being great progress in the component of metal dust, increased the composition of metallic nickel and metallic tin, adopt sintering, the mode of colding pressing, makes cutter head have larger intensity to improve, and possesses a little following: anti-wear performance is strong, and the life-span is strong.
Through detecting, bending strength moment is greater than 16N.m; Sharpness: cutting thickness is under 8.7cm/s, cutting thickness is 1.5～1.8cm; In service life: cutting thickness is 1.5～1.8cm, can cut area and be greater than 115m
2.

Nickel powder: 5～10%;
Cobalt powder: 5～10%;
Glass putty: 5～10%;
Zinc powder: 5～10%;
The mass concentration of described diamond solution is 30～40%.
The preparation technology of the cutter head of cutting granite, comprises the steps:
(1) by above-mentioned part by weight, metal dust and diamond solution are taken;
(2) above-mentioned compound is placed 2～4 hours at normal temperatures and pressures;
(3) above-mentioned compound is put into mould, at 4000Kgf/cm
2the forming under the pressure of colding pressing, and keep the pressure semi-finished product of 3 seconds;
(4) by semi-finished product, at 700 degrees Celsius, be raised to 800 degrees Celsius of insulations 2 minutes, be then warmed up to 900 degrees Celsius, obtain semi-finished product after sintering;
(5) semi-finished product after sintering are polished, join sand;
(6) be packaged into finished product.
The present invention can summarize with other the concrete form without prejudice to spirit of the present invention or principal character.Therefore, no matter from that, above-mentioned embodiment of the present invention all can only think explanation of the present invention can not limit invention, claims have been pointed out scope of the present invention, and scope of the present invention is not pointed out in above-mentioned explanation, therefore,, in the implication suitable with claims of the present invention and any variation in scope, all should think to be included in the scope of claims.
