Abstract
The invention relates to the field of production of diamond products, and discloses a method for manufacturing high-efficiency diamond geological drills. The method is mainly characterized in that single diamond cutter bits of drill teeth of a diamond geological drill are manufactured one by one in advance, the single diamond cutter bits are welded on a drill barrel of the diamond geological drill, and accordingly a novel diamond geological drill is manufactured. The manufacturing method brings revolutionary progress for the industry of diamond products. On account of the diamond geological drill, labor production efficiency is improved by 40 times at least, production cost is lowered by 37%, and simultaneously, full-automatic, standard and large-scale energy-saving and environment-friendly production of the diamond geological drills is realized.
Description
Technical field
The present invention relates to the diamond composition production field, laser welding technology is in the concrete application in diamond geology drill produced field specifically.
Background technology
For many years, diamond geology drill produced is nothing more than two kinds of manufacturing technique methods, and first kind is to electroplate (casting) production technology manufacturing approach; Second kind is hot pressed sintering production technology manufacturing approach.
First method is to prepare qualified bit matrix in advance, with bit drills tooth remainder sealing insulation wrapping, electroplates (casting) early stage then and handles; The whole charged groove of going into; At the brill tooth position of drill bit, cross coating through preplating one deck after, constantly pass through " go up sand-＞unload sand-＞thickening is fixing-＞go up sand-＞unload sand-＞thickening is fixing "; Boring the composite bed that tooth position deposit multilayer diamond combines with metal alloy; After reaching the requirement size, the dismounting frock clamp insulate with going, and promptly produces product through the later stage decorative Treatment again.
Second method is to prepare the bit matrix of preliminary working in advance, and assembling graphite frock clamp is at first filled metal dust or alloy powder at the brill tooth position of geology drill bit; As the metal alloy transition zone; Continue then to fill metal dust or metal alloy powders and adamantine compound, filled stone ink powder or other mouth of a river powder in the position, the mouth of a river of geology drill bit are put into hot-pressed sintering furnace through hot pressed sintering with the geology drill bit integral body that assembles at last; Be sintered to finished product; After removing graphite anchor clamps and mouth of a river graphite powder, carry out machining again and become diamond hot pressed sintering drill bit, promptly produce product through decorating at last.
Both are at common feature: all being that the drill steel body is whole assembles with frock clamp, produces the bit drills tooth then.The different first method of being is handicraft workshop production over nearly 20 years always, and technology is very backward, and the wasting of resources is very serious, unstable product quality, and cost is high.
Although " the last sand method (200910044406.9) of diamond bit " patent of invention of Xiao Yunjie has been set up the domestic unique plating that has independent intellectual property right (casting) automatic production line, on handicraft workshop production technology manufacturing approach basis, the unit are output value has improved 8 times; People from unit the output value has improved 10 times; Labour intensity reduces greatly, and production cost has reduced by 20%, and product percent of pass has improved 24%; Solved the contradiction of creeping into timeliness and can not have simultaneously service life; But it still can't realize truly full-automation, standardization, large-scale production, relies on workman's skilled operation degree equally, and production cost is still high; All simultaneously plating (casting) equipment; Especially diameter is more than 600mm, and for example the drill bit of above specifications such as 600mm, 800mm, 1000mm, 1200mm all receives great restriction, can't produce.
The hot-pressing sintering technique production method, all the time, in a sense; It comes simply than electroplating (casting) manufacturing technique method, and automaticity is higher, but energy consumption is high; Environmental pollution is more serious, and is bigger to adamantine damage, requires higher relatively to peopleware.Graphite jig consumption is very big, belongs to the process of high energy consumption high pollution high flow rate.Because the restriction of hot pressed sintering equipment, the above geology drill bit of diameter 300mm can't be produced.
Summary of the invention
The manufacturing approach that the purpose of this invention is to provide a kind of diamond geology drill bit of high-efficient energy-saving environment friendly.On the basis that does not change plating (casting) equipment and hot pressed sintering equipment; From truly realizing the full-automation of Electroplating Production, the production of energy-conserving and environment-protective is changed in standardization on a large scale; Solve heavy caliber diamond geology drill bit and restricted the great difficult problem that to produce always; Production cost reduces by 37% on original traditional handicraft basis simultaneously, and people from unit the output value will improve 20 times, and the output value of unit are improves more than 40 times; Labor productivity improves 40 times, and it gives diamond geology drill produced even production brings revolutionary progress to diamond composition.
Provide the production technology scheme that dual mode is arranged for achieving the above object:
First kind of mode; (casting) diamond segment or thermal pressing sintering diamond cutter head are electroplated in early-stage preparations; The brill tube finished product idiosome of the good geology drill bit of while machining; It is as a whole to utilize laser that the brill tube of diamond segment and geology drill bit is welded on request by laser-beam welding machine, carries out post-processed at last and decorates, and produces efficient diamond geology drill bit.
The second way: (casting) diamond segment or thermal pressing sintering diamond cutter head are electroplated in early-stage preparations; The thick idiosome of brill tube of the good geology drill bit of while machining; Utilize laser to be welded into the brill tube of diamond segment and geology drill bit as a whole on request by laser-beam welding machine; Requirement according to the geology drill bit makes other positions of brill tooth be processed into satisfactory size then, and decorating at last becomes diamond geology drill bit finished product again.
Before a kind of mode be machinery processing earlier, the production technology of back welding; A kind of mode in back is the production technology of machining after the welding earlier.When both weld, can adopt multiple mode to weld, most typical welding manner has two kinds.
First kind of welding manner is concavo-convex interface weld seam welding, helps strengthening the solder bond fastness like this.Second kind of welding manner is flat mouthful of butt weld welding, and that comes like this is simple and convenient.
Maximum of the present invention is characterised in that having split the bit drills tooth becomes monomer one by one; Workpiece reduces greatly; Be convenient to electroplate (casting) and hot pressed sintering, plating (casting) and hot pressed sintering are simplified greatly, can be comprehensively truly realization full-automation, standardization, large-scale production.The full-automation of laser weld, standardization, large-scale production have been well-known.
