The heating rate of 7 DEG C/min is warming up to 950 1100 DEG C, is then incubated 30 50min, last furnace cooling；
(5) carcass, the diamond saw head that sinter in step (4) are laser welded and are prepared as semi-finished product；
(6) semi-finished product in step (5) are carried out saw blade inspection, smooth, polish spray paint, put the first edge on a knife or a pair of scissors, pack, dispatch from the factory inspection system
Standby for finished product.
Use and have the beneficial effects that produced by technique scheme: the present invention is by improving the employing of saw blade tip formula
Pre-alloyed powder replaces cobalt powder to combine the style of corrugated teeth, uses the mode of laser welding to make and a kind of can the most dry cut
Diamond disc.Solve the problems such as cutter head easily occurs in ratio-frequency welding saw blade, and security performance is the highest, saw blade carcass component
Design is reasonably combined with diamond, uses laser welding to can effectively ensure that the use intensity of saw blade in addition, is avoided that thick
Sudden and violent use causes the injury of personnel.
Accompanying drawing explanation
Fig. 1 is the preparation technology flow chart of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Ground describes, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premise
Embodiment, broadly falls into the scope of protection of the invention.
Elaborate a lot of detail in the following description so that fully understanding the present invention, but the present invention is all right
Using other to be different from alternate manner described here to implement, those skilled in the art can be without prejudice to intension of the present invention
In the case of do similar popularization, therefore the present invention is not limited by following public specific embodiment.
Disclosure sets forth a kind of Laser Welding that can the most dry cut welding diamond disc, it is specific as follows:
1), concrete flow sheet is as shown in Figure 1；
(1) prepare carcass raw material and diamond saw head raw material according to formula described above, and stir respectively；
(2) Laser Welding preparing the most dry to cut welds carcass mould and the diamond saw head mould of diamond disc
Tool；
(3) the carcass raw material and the diamond saw head raw material that step (1) are mixed respectively are respectively placed in carcass mould, gold
Hard rock saw head mould tool carries out cold moudling；
(4) carcass, the diamond saw head of step (3) cold moudling are put into sintering machine and be sintered, first with 4 during sintering
The heating rate of 7 DEG C/min is warming up to 950 1100 DEG C, is then incubated 30 50min, last furnace cooling；
(5) carcass, the diamond saw head that sinter in step (4) are laser welded and are prepared as semi-finished product；
(6) semi-finished product in step (5) are carried out saw blade inspection, smooth, polish spray paint, put the first edge on a knife or a pair of scissors, pack, dispatch from the factory inspection system
Standby for finished product.
2), the technical scheme that a kind of diamond disc that can the most dry cut makes:
The component of carcass, according to the dry performance requirement of cutting of saw blade, saw blade carcass sword to be obtained is fast, does not burn carcass, diamond energy
Effective reasonable employment rationally comes off.It includes carcass and diamond saw head, and described carcass includes following weight percent content
Component: Fe30%-40%, containing Co alloyed powder 25%-35%, more than Cu20%-30%, Ni8%-12%, Sn2%-5%, Cr
Amount.
The alloyed powder Ingredient percent containing Co is:
Nickel: 1-12wt%, tungsten: 1-3wt%, carbon: 0.20-1.5wt%, chromium: 10～20wt%, molybdenum: 10～15wt%,
Silicon: 2～8wt%, cobalt: surplus.
The collocation of diamond, it is contemplated that can the most dry cut, it is necessary to saw blade tip is sharp, cutting efficiency wants height, shock resistance
Performance to be got well, comprehensive requirements above, and diamond saw head includes the component of following weight percent content: granularity is 35/40 mesh, by force
The diamond 0.8%-15% of degree >=16kg；Granularity is 40/45 mesh, the diamond 8%-12% of intensity >=12kg, and granularity is 45/
50 mesh, the diamond 2%-8% of intensity >=10kg.
The present invention is primarily directed to dry cutting concrete and granite, with optimize design method, drawn a kind of preferably
Saw blade tip formula, in identical cost of manufacture, under same cutting efficiency, it is possible to effectively carry out the most dry cutting, tool
There are bigger economic benefit and social benefit.
Along with the rise of the various goods and materials costs such as cost of labor, electricity, water, people increasingly pursue efficiency, to diamond circular
The sharpness of saw blade requires more and more higher, and a lot of local saw blades are in use due to the restriction of various conditions abroad
The mode that generally employing does not adds water is cut, and chip removal, the cooling capacity of saw blade are required more and more higher, to saw blade by these
Security requirement is more and more higher, when saw blade reaches certain cutting speed, owing to chip removal, rate of cooling cause saw blade slowly
Cutter head and the fricative high temperature of cutting object, cause part diamond carbonization, and cutting speed reduces.We use system of the present invention
The diamond disc that the product made makes with conventional formulation was contrast experiment, and experimental result is as follows:
Cutting object: 450mm × 450mm × 20mm tri-flower granite and 450mm × 450mm × 50mm band reinforced concrete
Soil block
Cut machine performance: rotating speed 3500RPM, power 5.5KW, do not add water without cooling condition.
