Abstract
The invention discloses a pre-alloyed ultra-fine powder carcass diamond tool, which belongs to nonmetal cutting tools. The diamond tool consists of a steel base body and a tool bit, wherein the tool bit consists of diamond and a carcass metallic bonding agent, and the carcass bonding agent comprises the following components in percentage by weight: 70 to 90 percent of pre-alloyed ultra-fine powder, 8 to 18 percent of copper powder, 2 to 6 percent of tin powder, 1 to 4 percent of nickel powder and 1 to 2 percent of paraffin. The bonding agent of the diamond tool mainly takes the pre-alloyed ultra-fine powder as the main component, the cost of the bonding agent of the diamond tool is reduced by 60 to 65 percent compared with the cost of a cobalt-based agent or a nickel-based agent, and the sharpness is improved by 55 to 60 percent, so the processing efficiency is greatly improved. The pre-alloyed ultra-fine powder carcass diamond tool is widely used in the fields of building materials and the like.
Description
Technical field
The present invention relates to a kind of diamond disc that is used for construction materials such as processing stone material, particularly relate to ultra-fine prealloy base diamond saw blade bond.
Background technology
Diamond disc is made up of a steel matrix and the cutter head two parts that are embedded on the matrix; The steel matrix has a centre bore; This saw blade is installed on the drive shaft rotating through said centre bore; Support the peripheral cutter head of steel matrix; Diamond in the cutter head plays main dissection; Diamond is used for fragmentation; Grind processed material; Bond plays the protective money hard rock and controls diamond not by too early coming off; And wear and tear synchronously with diamond, so the performance of bond role in whole saw blade is most important.The sizable a part of work high above the ground in construction site on the market now; Require dried cutting, in the face of the dried market of cutting that enlarges day by day, in the first generation technology; The bond that is used to make diamond disc is cobalt-based mostly; Ni-based etc., and exist with the form of simple substance powder, the saw blade that this bond is made is worked under anhydrous state; Saw blade can produce the high temperature about 850 degree at cut point; Can cause saw blade to burn tooth, can't normally use, until scrapping.This type bond is poor to market adaptability, and serviceability does not reach requirement, and cost is high, lacking of market competition ability.So produced second generation technology thereupon; Prealloy based powders bond; Though can satisfy dried requirement of cutting; But the distinctive spherical form of prealloy; Determined that the prealloy forming property is poor, limited the adding of prealloy content, general addition has reached the limit of 55%; Influenced the performance of prealloy performance, the bottleneck that becomes the prealloy development of forming property.
Summary of the invention
Technical problem to be solved by this invention is to avoid the deficiency in the above-mentioned technology, and a kind of good processability that has is provided, and can effectively improve carcass heat conduction; Heat radiation, heat-resisting and function admirable; Cost is low, can satisfy the diamond tool of existing market demand fully.Technical scheme of the present invention is: prealloy superfines carcass diamond tool; Constitute by steel matrix and cutter head; Cutter head is made up of diamond and carcass metallic bond; The compositions in weight percentage of carcass bond is: prealloy superfines 70%-90%; Copper powder 8%-18%; Glass putty 2%-6%, nickel powder 1%-4%, paraffin 1%-2%.
Diamond tool bond component of the present invention mainly is to be main with the prealloy superfines; Prealloy superfines Fisher particle size is less than 5 μ m; It is that soluble metallic salt and deionized water are configured to the aqueous solution that the prealloy superfines is made basic mechanism; Add alkaline solution then; Reaction generates the hydroxide or the subcarbonate co-precipitation of metal; Through washing; Suction filtration; Calcining obtains the nanoscale composite oxide power; Through broken; Ball millings etc. obtain finished product prealloy superfines, and its preparation method is different from the aeroponics production method of prealloy fully.
Further optimize, optimal case does, percentage by weight prealloy superfines 86%, and copper powder 10%, glass putty 2%, nickel powder 1%, paraffin 1%, the sintering temperature of this bond is a 700-740 degree Celsius.
Adopt the diamond tool of prealloy superfines making, utilize the unique advantage of prealloy superfines, changed the basic situation of diamond tool, the present invention has following advantage:
1: prealloy superfines carcass diamond tool, owing to the adding of prealloy superfines, improved the processability of carcass, broken through the bottleneck of moulding issues limit prealloy development.
2: prealloy superfines carcass diamond tool; Because the adding of prealloy superfines; Heat conduction; Heat-resisting effect has obtained tangible improvement; Can be used for dried cutting fully; Solved the not competent difficult problem of cutting of simple substance powder in the past, than cobalt-based in the past, Ni-based bond has reduced the cost of 60%---65%.
3: prealloy superfines carcass diamond tool; Because with the prealloy superfines is basic powder; Greatly reduce the required activation capability of the diffusion of metallic atom in the sintering process; Specific area is big; Sintering activity is strong, and it is good to show as sintering character in the red sight, and sintering temperature is low; Sintering time is short, than common diamond tool tyre case economize on electricity about 30%.
4: prealloy superfines carcass diamond tool; Because the adding of prealloy superfines; In sintering process, accomplish the alloy homogenising rapidly; Its sintered article HRB is higher than more than the composition simple substance powder sintering goods HRB10 of the same race; So under the constant situation of abrasion resistance, improved carcass greatly to adamantine support with protect the edge ability; Thereby obtain very high sharpness, sharpness has improved 55%---60%, has improved working (machining) efficiency greatly.
The specific embodiment
Embodiment below in conjunction with concrete further specifies the present invention:
Embodiment 1, gets prealloy superfines 75%, copper powder 15%, and nickel powder 4%, glass putty 5% is put into mixing tank, mixes 0.5 hour, adds paraffin 1%, continues to mix 2.5 hours, and sintering temperature is 700 ℃ Celsius---740 ℃.Batch mixing takes by weighing corresponding weight by job requirements after finishing, and the steel grinding tool of the corresponding specification of packing into carries out cold pressing process, suppresses the satisfactory embryo of colding pressing, and carries out hot pressed sintering again and is made into diamond tool.
Embodiment 2, get prealloy superfines 80%, copper powder 10%, and nickel powder 3%, glass putty 6% is put into mixing tank, mixes 0.5 hour, adds paraffin 1%, continues to mix 2.5 hours, and sintering temperature is 700 ℃ Celsius---740 ℃.Batch mixing takes by weighing corresponding weight by job requirements after finishing, and the steel grinding tool of the corresponding specification of packing into carries out cold pressing process, suppresses the satisfactory embryo of colding pressing, and carries out hot pressed sintering again and is made into diamond tool.
Embodiment 3, get prealloy superfines 87%, copper powder 8%, and nickel powder 2%, glass putty 2% is put into mixing tank, mixes 0.5 hour, adds paraffin 1%, continues to mix 2.5 hours, and sintering temperature is 700 ℃ Celsius---740 ℃.Batch mixing takes by weighing corresponding weight by job requirements after finishing, and the steel grinding tool of the corresponding specification of packing into carries out cold pressing process, suppresses the satisfactory embryo of colding pressing, and carries out hot pressed sintering again and is made into diamond tool.
