【摘要】 对多模变薄拉深过程进行了详细分析。指出多模变薄拉深工艺可以充分发挥材料的塑性变形能力 ,使原来需要经过几次单模变薄拉深才能制成的管坯一次即可完成。在对多模变薄拉深变形过程进行分析的基础上 ,将多模变薄拉深工艺技术应用于波纹管管坯大批量生产中。更多还原

【Abstract】 A mechanics module is established for multi-die ironing process,of which the analysis is also going to be discussed in details.Tests have show that with this technology imporovement the full use of material malleability can be made.This makes the ironing process being able to be completed in just one go which used to take several steps with single die ironing techology.Further to the analysis of multi-die ironing process,this research is trying to apply the successful engineering system to mass production of blank tube with the purpose of technology improvement for bellows production in our country.更多还原
