一、引言出于降低生产成本的需要,冷锻技术在零部件的生产中得到了日益广泛的应用,尤其是在大批量生产的工业部门,其发展更是势在必然。总的说来,对冷锻技术的需求在不断增长着,这主要是由于能从而获益于减少或完全消除机械加工,具有高度的潜在价值,还由于这种技术在利用材料的加工硬化特性方面具有潜在的优越性,生产的零件其强度与用更为昂贵 I. INTRODUCTION In order to reduce the cost of production, cold forging technology has been widely used in the production of parts and components, especially in the mass production of the industrial sector, its development is inevitable. In general, the demand for cold forging technology is on the rise, mainly due to the high potential value that can be gained from reducing or eliminating machining altogether, and because of the use of this material for work hardening Aspects have potential advantages and the parts produced are more expensive and expensive to use
