Abstract
The invention discloses a method for manufacturing copper-iron-based diamond cutter teeth. The method is characterized by including the following steps of preparing green body material through framework material and adhesive metal, mixing the material after preparation, packaging the material after mix so as to be subjected to thermal pressing formation, cooling the material after thermal pressing formation, and machining the material after cooling, wherein the material prepared in the green body material preparation process include, by weight, 35% of iron powder, 50% of copper powder, 5% of cobalt powder, 5% of nickel powder and 5% of manganese powder, diamond accounting for 5.04% of the total weight of the green body material is added in the mixing process, the material is mixed in a stainless steel ball mill, the material to ball ratio is 1:2, the rotation speed of the ball mill is 46 r/min, the material mixing time ranges from 12 hours to 35 hours, the sintering temperature in thermal pressing formation is 1020 DEG C, the sintering time ranges from 5 minutes to 10 minutes, the pressure ranges from 12 Mpa to 13 Mpa, and the tapping temperature is 550 DEG C.
Description
Technical field
The present invention relates to a kind of manufacture method of diamond cutter tooth, especially a kind of manufacture method of copper iron-based diamond cutter tooth.
Background technology
On market manufacturing in the process of diamond cutter tooth, need some fixed cutting elements to make adamantine binding agent, binding agent is divided into metal adhesive, resinoid bond, vitrified bonding etc., in framework material, to use metal carbides, can play raising toughness, suitably reduce the effect of wearability.In prior art in order to obtain the high temperature hardness of diamond cutter tooth, manufacturer adopts cobalt-based element (containing cobalt amount 50 ~ 99%) to manufacture mostly both at home and abroad, because the property sintering carcass of cobalt powder has higher compactness and sintered material hardness, make cobalt-based diamond bit sharp durable again in the time of cutting diamond concrete, but cobalt element is mineral resources more rare on the earth, expensive, and the drill bit that makes of the diamond cutter tooth making with additive method not have be sharp wear-resisting performance again.
Summary of the invention
The object of the invention is to solve and use cobalt-based element making diamond cutter tooth cost high, it is the sharp problem of wear-resisting performance again that the drill bit that the diamond cutter tooth making with additive method makes does not have.
The technical solution used in the present invention is: a kind of manufacture method of copper iron-based diamond cutter tooth, comprise the following steps: with framework material and bonded metal carry out carrying out after the preparation of carcass material, preparation batch mixing, batch mixing complete after charging carry out carrying out after hot-forming, hot-forming after cooling, cooling carrying out machining, the batching in wherein said carcass material process for preparation comprises that iron powder 35%, copper powder 50%, cobalt powder 5%, nickel powder 5%, manganese powder 5%(are all weight percentage above); In batch mixing process, adding weight is 5.04% diamond of carcass material gross weight, and batch mixing carries out in rust steel ball grinder, and material ball ratio is 1:2, and ball mill revolution is 46r/min, and mixing time is 12～35h; 550 DEG C of 1020 DEG C of sintering temperatures when hot-forming, sintering time 5～10min, pressure 12～13Mpa, tapping temperature.
The beneficial effect that the present invention adopts is: adopted after technical scheme of the present invention, the cobalt content of diamond cutter tooth is less than 10%, reduce the consumption of rare metal, improved the high temperature hardness of diamond cutter tooth, the speed that adopts thin faced bit cutting concrete intensity that this diamond cutter tooth manufactures to be greater than 45mm/min, cutting reinforcing bar cross section is greater than 560mm/min, bit life can reach 30m.
Detailed description of the invention
The present invention relates to a kind of manufacture method of copper iron-based diamond cutter tooth, comprise the following steps: with framework material and bonded metal carry out carrying out after the preparation of carcass material, preparation batch mixing, batch mixing complete after charging carry out carrying out after hot-forming, hot-forming after cooling, cooling carrying out machining (machining refers to diamond cutter tooth is put the first edge on a knife or a pair of scissors), the batching in wherein said carcass material process for preparation comprises that iron powder 35%, copper powder 50%, cobalt powder 5%, nickel powder 5%, manganese powder 5%(are all weight percentage above); In batch mixing process, adding weight is 5.04% diamond of carcass material gross weight, and batch mixing carries out in rust steel ball grinder, and material ball ratio is 1:2, and ball mill revolution is 46r/min, and mixing time is 12～35h; 550 DEG C of 1020 DEG C of sintering temperatures when hot-forming, sintering time 5～10min, pressure 12～13Mpa, tapping temperature.Adopt after technical scheme of the present invention, the cobalt content of diamond cutter tooth is less than 10%, diamond concentration is less than 50%, reduce the consumption of rare metal, improve the high temperature hardness of diamond cutter tooth, the hardness of diamond cutter tooth capable of regulating within the scope of HRC21-1-HRC84, the speed that adopts thin faced bit cutting concrete intensity that this diamond cutter tooth manufactures to be greater than 45mm/min, cutting reinforcing bar cross section is greater than 560mm/min, bit life can reach 30m.
Those skilled in the art should know; protection scheme of the present invention is not limited only to the above embodiments; can also on the basis of above-described embodiment, carry out various permutation and combination and conversion; under the prerequisite without prejudice to spirit of the present invention, the various conversion that the present invention is carried out all drop in protection scope of the present invention.
