Cutting pick is a kind of widely-used consumptive mining tool.The traditional producing technics of cutting pick body is foundry,or machining after roughly forging,or machining directly from metal bar.By former technics,the property of products is poor,and by the latter,the material availability is low and the cost is high.The patent technology for cutting pick body warm extrusion introduced can overcome all the disadvantages mentioned above.By analyzing the characteristic of cutting pick body warm extrusion,adopting the principle of power balance to solve the strain forces the approximate solution,the approximate calculating formulas of extruding power were deduced.The main factors affecting on extruding power were determined.This research can provide a theory busis for signing mould and choosing proper equipment for this new technology.
