Coal Mining Machine Spare Part Cutter Pick U 82 Conical Tools

The concial pick of coalcutter and development machine is a very important part of digging equipment in coal mine, whose performance directly influences the mining efficiency. After full analysis of cutting mechanism of pick cutter and comprehensive stress of extrusion, shearing and striking born in cutting coal bed, coal rock mixing bed and light, medium and heavy working conditions of rock strata, we make use of our company independent research and development of "Micro-arc plasma precision cladding", "accurate powder feeding", "vaporized isogranular alloy ceramic powder", "IGJR-2B numerical control plasma pick cladding machine tool" to product a new type of cladding pick cutting, the outside surface on the top conic of pick cutter is cladded with the strengthening layer with high hardness and toughness, enhancing the wear resistance of the cone, preventing pick head from falling off early. When brazing alloy head, to make the mcrocellular processing of outside surface and corresponding inside surface of alloy head, enlarging the welding area, strengthen the humidity among the solder, cutting head and body, simultaneously select the America-imported solder and flux, welding strength increased 30%. Additionally, the cutter body adopts one-step forming process of 42CrMo Material precision cold forging, also significantly improving mechanical strength itself.
The pick cutter produced by adopting many kinds of new technologies and processes greatly improves the service life, with the characteristics of no spark producing when impacting on the rock in the meantime. It is called "no spark wear-resisting pick cutter" in the industry.

Features:
1.No spark produces when the cladding layer impacting on the rock, much safer when working in high gas coals mine.
2.The cladding layer enhances the wear resistance of cutter body, and prevents the alloy head from falling off.
3.The cutter body adopts one-step forming process of 42CrMo Material precision cold forging, improving the comprehensive mechanical strength.
4.It is designed with discharge launder at the bottom of the big end, to strengthen the rotation ,effectively avoiding eccentric wear caused by clamping.
The manufacturing method of new-type pick cutter has won national invention patent. Patent No. ZL200910064540.5
