【Abstract】 By energy method this paper calculated the spreading deformation of double-wedged forging parts through several small steps of deformation, summed up the influence regularity of relative reduction and the ratio of width to height of the blank on spreading coefficient, concluded the calculating formula of spreading coefficient using mathematical inductive method. Proved by simulated test and engineering practice, this method is feasible, accurate and useful and has great significance to direct roll forging technology and tool design.更多还原
