Coal cutter, gear, gear seat, U82, U84, U85, U92, U94, U95, U47, U765, U76, U119, U138, C31, S100, S120, S150, S160, S170, 75C, B47K223050, C31HD, C21HD, No. 13, No. 23, No. 55, complete specifications, high strength, good abrasion resistance, long service life. This product is made of high strength alloy steel after heat treatment, high strength and toughness and high wear resistance. Widely used in all kinds of fully mechanized mining machine, fully mechanized mining machine, continuous mining machine. According to different coal and semi coal rock design and production performance of different cutting teeth, to meet the different needs of customers. At the same time, design, production, maintenance, cannon boring head drum of shearer.
Two, coal cutter is the vulnerability of mining machinery, analysis and Research on the long-term coal cutter company through analyzed the reliability of coal cutter selection, from several new coal cutter teeth arrangement and coal cutter structure improvement etc.. Improve the reliability of the coal cutting, reduce the proportion of the cost of the coal cutting in the cost of tons of coal, improve the effective working time of shearer. 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　
Three, the use of coal cutting teeth: mainly used in coal mining and tunnel, tunnel, ground trenching and other engineering excavation. Mainly with Shearer boring machine, milling machine and other equipment.
Coal cutter model mainly based on coal mined coal hardness, division of tooth holder type and other factors, the pick is divided into: U62, U47, U82, U84, U85, U82, U92, U94, U95, S100, S120, S135, S150, S160, S170 and other models, such as a special type of quantitative production.
The coal picks the tooth body to select the high strength alloy steel after the heat treatment, maintains the high strength toughness and the high abrasion resistance; the clamp spring is made of the high strength spring steel.
The cutting head of coal is processed by isothermal quenching process, and the hardness is not reduced. Cemented carbide using the domestic production of regular YG13C, quality stability. According to customer needs to increase the wear layer. Hardness above 65 degrees.
Four, the advantages of coal cutting:
1, long service life, is the traditional coal cutting 1-1.5 times.
2, high efficiency: is the old coal cutting teeth 2.5 times.
3, energy efficiency is good: because of the replacement of a large number of decline, shorten the coal mining machine downtime, reduce the mining cost. Yield quality standard:
A, cone hardness: HRC > 65B, cutting rod hardness: HRC28 degrees -32 degrees C,
Surface hardness: HV > 2000 by special heat treatment, reach 4045, surface oxidation
