Abstract
The present invention relates to a kind of full powder ultrathin diamond saw blade, its matrix element forms and mass percent formula is: Cu45-65%;Sn8-12%;Co8-12%;Ni2-4%;Ag2-4%;S0.3-0.5%;P0.2-0.3%;C0.2-0.3%, remaining is Fe, by 0.88 gram/cm of standard diamond content3Being 100% densitometer, diamond concentration is 16-28%.Owing to present invention employs above technical scheme, the invention have the advantages that one is without matrix, greatly reduce the waste of matrix;Two is that its thickness is up to 0.3-0.6;Three is that cutter head height reaches the 30% of saw blade external diameter, long product lifecycle, and cutting efficiency is high, and saw kerf is little.
Description
Technical field
The present invention relates to metallurgical technology field, be specifically related to a kind of hybrid metal slim diamond blade.
Background technology
Existing carrier matrix saw blade, middle usually 65Mn material steel disc matrix, after cutter head makes to be finished, steel disc matrix can not be reused, causing steel to waste, conventional steel sheet matrix accounts for cost shared by the 10%-15% of whole saw blade material cost, noise cancelling type steel disc matrix and sandwich type steel disc matrix and compares Lie Genggao.
The quality of steel limits so that it is the thinnest that conventional steel matrix saw blade thickness can not do.In general, the saw blade of external diameter Φ 100mm specification, matrix thickness 0.8mm, cutter head 1.0mm, reach capacity.Owing to saw blade thickness is high, so kerf width reaches 1.0mm so that the loss of cut material is big, cut waste of material is serious.
Summary of the invention
It is an object of the invention to provide a kind of full powder ultrathin diamond saw blade, once-forming without the full powder of matrix, its thickness be thickness be 0.3-0.6.Service life is long, and cutting efficiency is high.
In order to solve the problem existing for background technology, the present invention is by the following technical solutions: its composition and mass percent formula be: Cu45-65%;Sn8-12%;Co8-12%;Ni2-4%;Ag2-4%;S0.3-0.5%;P0.2-0.3%;C0.2-0.3%, remaining is 100% densitometer for Fe by 0.88 gram/cm3 of standard diamond content, and diamond concentration is 16-28%.
2, a kind of hybrid metal slim diamond blade, it is characterised in that: its preparation method:
A), get the raw materials ready---by component design, the raw and auxiliary material that matrix element and diamond etc. are required is prepared;
B), mixing---by being poured on mixed powder together and diamond stirring, sieve with screen cloth, the powder having crossed sieve is poured into mixing in batch mixer; after shutdown, then sieve with screen cloth, take off flat with steel spoon powder; estimate and check errorless after, enter next operation;
C), die-filling precompressed---by mixed powder detection apparent density, calculate the die-filling required height of powder according to apparent density, powder is loaded in mould, carry out precompressed;
D), hot pressed sintering---the mould pressed through in advance is put into vacuum sintering furnace, hot pressed sintering;
E), smooth---by burned saw blade sand papering; remove flash removed; separate layer by layer with the high purity graphite block of flat smooth and put into clock hood type furnace; it is passed through protection gas shielded, comes out of the stove after heating and thermal insulation, continue to be passed through protection gas shielded; 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 hard alloy reamer, 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 blade grinding machine and puts the first edge on a knife or a pair of scissors;
H), spray paint printing package---saw blade surface is sprayed uniformly the paint of last layer required color,
Then lettering, packaging.
Beneficial effects of the present invention: one is without matrix, greatly reduces the waste of matrix;Two is that its thickness is up to 0.3-0.6;Three is that cutter head height reaches the 30% of saw blade external diameter, long product lifecycle, and cutting efficiency is high, and saw kerf is little.
