Abstract
The utility model relates to a cutting pick cylindrical tooth for a mining machine in the coal industry, in particular to a cutting pick cylindrical tooth for a composite bed mining machine, which needs to solve the technical problems that the existing cutting pick cylindrical tooth for a mining machine is a single-structure hard alloy cylindrical tooth, and has non-deal hardness and wear resistance and is easy to wear under the condition of high rock hardness. In order to solve the technical problems, the cutting pick cylindrical tooth adopts the technical proposal that the cutting pick cylindrical tooth is formed by the compounding of a hard alloy substrate and diamond layers, the diamond layers are distributed at intervals on the outer surface of a conical body at the upper end of the hard alloy substrate, and the diamond layers are fixedly molten with the hard alloy substrate.
Description
Technical field
The utility model relates to coal industry digger pick post tooth, particularly relates to a kind of composite bed digger pick post tooth.
Background technology
Pick is the strength member on the digger, also is the consumption maximum, the part of easy damage.The technical requirements regulation of People's Republic of China's coal industry standard " colliery pick MT246-1996 ": the colliery is to be welded by the denticle and the hard alloy columnar teeth that adopt structural alloy steel with pick.Hard alloy columnar teeth is the groundwork position in the digger pick, also is the main stress part.Hard alloy columnar teeth is general all can operate as normal under the rock stratum hardness below the f6, during the above rock stratum hardness of f6, adopts the single structure hard alloy columnar teeth just undesirable on hardness and abrasion resistance, be worn easily, increase a lot of number of times of changing pick, inefficiency has improved mining costs.
The utility model content
The technical problems to be solved in the utility model is, existing digger pick post tooth single structure hard alloy columnar teeth, and under the harder situation of rock stratum hardness, the undesirable deficiency that is worn easily of hardness and abrasion resistance.
For solving the problems of the technologies described above technical solution adopted in the utility model be, it constitutes described diamond layer and described hard alloy substrate blow by diamond layer spaced apart on hard alloy substrate and the described hard alloy substrate upper end outer surface of cone is compound.
The utility model can be realized by following process: the first step, handle matrix.On the compound position of outer surface of cone, described hard alloy substrate upper end, cut groove with laser cutting machine; Second step, batching.Selecting particle mean size for use is that 10 microns diadust 84-90% (weight) and the NiFeCo of 10-16% (weight) fully mix in the ratio of 70:25:5; The 3rd step: assembling.Described hard alloy substrate and the compound special graphite jig of packing into is carried out being assembled into the synthetic piece of pyrophyllite after the application of vacuum; In the 4th step, HTHP is synthetic.The synthetic piece of described pyrophyllite is placed in the cubic hydraulic press, under the condition, synthetic behind 60s-90s between 1200 ℃-1500 ℃ and 5.0-5.6GPa.Diamond film forms described diamond layer together.The Part of Co molecule oozes and is fused in the described hard alloy substrate in the described diamond layer, makes described diamond layer and described hard alloy substrate blow; The 5th step, mechanical integer.The digger pick post tooth that is combined into after synthetic is carried out ball milling and makes.
The utility model with there to be technology to compare, because design has described diamond layer spaced apart on the outer surface of cone of described hard alloy substrate upper end, characteristics superhard, high wear resistance ratio that described diamond layer has, its beneficial effect is, strengthen the hardness and the anti-wear performance of digger pick post tooth on the one hand, kept the self-sharpening and the toughness of carbide alloy on the other hand again.Its anti-wear performance is more than 20 times of general hard alloy columnar teeth.Not easy to wear under the formation hardness condition with higher yet, improved the application life and the operating efficiency of digger pick, reduced mining costs.
