Abstract
The invention relates to a copper base diamond saw blade, which comprises a cutter head and a steel base body and is characterized in that the cutter head is made by mixing and firing metal powder, abrasive grade diamond and nano grade diamond; and the metal powder comprises pure copper powder, iron powder, nickel powder, tungsten carbide, tin powder and bronze powder. The preparation method comprises the steps of: uniformly mixing the metal powder according to a proportion; sequentially adding the abrasive grade diamond and the nano grade diamond for mixing; finally adding liquid olefin; packing the mixed formed material into a cold pressing mould to form; and sintering to prepare the diamond saw blade. Compared with the prior art, the diamond saw blade has the advantage that the abrasive grade diamond and the nano grade diamond are simultaneously added in the saw blade for achieving the purpose of organically combining the cutting function of the abrasive grade diamond with the friction-reducing abrasion resistant function of the nano grade diamond, therefore, the copper base diamond saw blade has effective sawing performance and better abrasion resistant performance. Compared with a similar saw blade, the copper base diamond saw blade has obviously enhanced service life by a test.
Description
Technical field
The present invention relates to diamond saw blade, especially relate to a kind of wear resistant copper-based diamond saw blade, this saw blade is applicable to granite and marmorean processing.
Background technology
The most general instrument of sawing stone material is a diamond saw blade, and the quality of its performance is the key of decision processing of stone cost and efficient.Diamond saw blade is made of three parts: diamond, bond, matrix.Diamond saw blade is sorted out by the difference of bond type and approximately is divided into cobalt-based diamond saw blade, iron-based diamond saw blade and copper base diamond saw blade.According to different cutting objects, select the product of different bonds for use.The cobalt-based diamond saw blade has advantages such as hardness height, wearability be good, but costs an arm and a leg and the sintering temperature height, and its development trend is to replace cobalt-based with low cobalt or non-cobalt-based.Iron-based diamond saw blade advantage be cheap, production technology is simple, but toughness and self-sharpening are poor.The sintering temperature of copper base diamond saw blade is low, low, the good toughness of price, but wearability is relatively poor, and saw blade is easy to wear in working angles, has a strong impact on the life-span of diamond saw blade.Therefore develop the needs that a kind of novel wear resistant copper base diamond saw blade becomes a reality.
Summary of the invention
The object of the invention provides a kind of novel wear resistant copper base diamond saw blade at the problems referred to above just.This invention adds abrasive-grade diamond and nano-diamond simultaneously in the saw blade carcass, utilize on the one hand nano-diamond because of specific area is big, hardness and the high effect that has antifriction antiwear in sawing process of intensity, improves the wearability of saw blade; Utilize the shear action of abrasive-grade diamond to guarantee the sharpness of saw blade on the other hand.
The objective of the invention is to be achieved through the following technical solutions: copper base diamond saw blade of the present invention is made of cutter head and steel matrix, and cutter head is to be formed by metal powder, abrasive-grade diamond and nano-diamond mixed sintering.Metal powder is made up of following component in percentage by weight: pure copper powder (Cu): 36-40%, iron powder (Fe): 17-22%, nickel powder (Ni): 8-12%, tungsten carbide (WC): 1-4%, glass putty (Sn): 4-7%, bronze powder (Cu-10Sn): 21-28%.The concentration of abrasive-grade diamond is 16-20%, and the concentration of nano-diamond is 2-10%.
The purity of described metal powder is all more than 99%; Described bronze powder (Cu-10Sn) component content is a copper 90%, tin 10%.
The granularity of described abrasive-grade diamond is 40/50, and the average grain diameter of described nano-diamond is 200nm.
The preparation method of copper base diamond saw blade of the present invention may further comprise the steps:
A, earlier metal powder is mixed by proportioning, add abrasive-grade diamond successively again and nano-diamond mixes, add atoleine at last and mix, the addition of paraffin is the 0.8-1.2% of whole raw material weight;
B, the molding mass that mixes and steel saw blade matrix are packed in the cold stamping die into cold moudling under 2 tons/square centimeter pressure;
After the saw blade demoulding of c, cold moudling, carry out sintering in the bell jar stove, feed hydrogen as reducing atmosphere, sintering temperature is 880 ℃ and is incubated 60min.When insulation 55min, begin pressurization, hot pressing pressure: 40KN, release behind the heat-insulation pressure keeping 5min.The cooling cooling promptly gets diamond saw blade.
The present invention's advantage compared to existing technology is: added abrasive-grade diamond and nano-diamond simultaneously in saw blade, realized the purpose that the antifriction antiwear effect with the shear action of abrasive-grade diamond particle and nano-diamond organically combines, made copper base diamond saw blade have efficient sawing performance and wearability preferably.After tested, saw blade of the present invention is compared with similar saw blade, and can reach 119.8-132.4m its service life, has improved 14.1-26.1% its service life.
The specific embodiment
The present invention is described further below in conjunction with embodiment, but is not restriction the present invention.
Embodiment one:
With pure copper powder (Cu): 36%, iron powder (Fe): 17%, nickel powder (Ni) 8%, tungsten carbide (WC): 4%, glass putty (Sn): 7%, bronze powder (Cu-10Sn): 28%, after mixing, add abrasive-grade diamond concentration 16% successively and nano-diamond concentration 2% mixes once more, add atoleine at last and mix.With the cold moudling in the cold stamping die of packing into of the steel matrix of the molding mass that mixes and saw blade, put into the bell jar stove after the demoulding, sintering under hydrogen reducing atmosphere, 880 ℃ of sintering temperatures, insulation 60min begins pressurization, pressure 40KN when insulation 55min, heat-insulation pressure keeping 5min, after the cooling cooling diamond saw blade, after saw blade put the first edge on a knife or a pair of scissors, be that the sawing object carries out reality and cuts with Fujian 603 granite plates, sheet material specification: long 660mm, thick 20mm.Each saw blade repeats dried cutting 6 times, writes down before the sawing of saw blade diameter behind the diameter and sawing respectively.The saw blade abrasion resistance is calculated by following formula: S=(H/ Δ h) * L
In the formula: S-service life (m)
