Paper Title:
Researches of Warm Extrusion Forming Technology and Property on 42CrMo Steel Cutting Pick
  Abstract

Cutting pick is a kind of widely-used consumptive mining tool, however its body is easy to break in the mining producing process, the problem that pick body easy to break could be solved by using the warm extrusion forming techniques under the premise of without raising the material level. This paper mainly focuses on the structural characteristics and material technological properties of 42CrMo high-strength steel cutting pick body, and adopts the power balance principle got the approximation of the deforming force, and derived the approximate calculation formula of warm extrusion force for cutting pick body; and analyzed the temperature field, equivalent stress, strain field and metal’s flowing rate field of warm extrusion forming by adopting numerical simulation method, and verified the result with the experiment. The result shows that the material organization grains of cutting pick produced by the new technique could be refined; the pressing direction of cutting picks’ shape outline forms forging streamlines, the quality is good. In a word, this new technique could completely meet the requirement of cutting pick.
