摘要/Abstract

摘要： 研究了板材充液成形过程中影响反胀效应的因素。将反胀效应划分为初始反胀(IIB)和局部反胀(LIB)。IIB的主要参数为反胀高度率(H_Ib/t)和反胀压力率(p_Ib/t),LIB受到IIB的影响并且与成形过程中液室压力直接相关。通过数值模拟得到了半球底筒形件和平底筒形件的最优反胀参数,并优化了对反胀效应有较大影响的凸模与压边圈间隙以及压边圈入口圆角等工艺参数,使反胀效应在充液成形过程中发挥了更大的作用。最后,试验验证了数值模拟结果的正确性。

Abstract: The factors that influence the inverse bulging effect in sheet hydro-mechanical deep drawing are investigated. According to different inverse bulging processes, two modes can be singled: the Initial Inverse Bulging (IIB) and the Local Inverse Bulging (LIB). IIB includes two parameters: inverse bulging height ratio (H_Ib/t) and inverse bulging pressure (p_Ib/t). LIB is influenced by IIB and has a direct relationship with liquid chamber pressure in the forming process. The optimal inverse bulging parameters of hemispherical bottom cylindrical part and flat bottom cylindrical part are obtained by numerical simulation. The process parameters, including the clearance between the punch and blank holder, and the radius of the blank holder entrance, which strongly influence the inverse bulging effect, are optimized, so as to make the inverse bulging effect behave better in hydroforming process. The accuracy of the numerical simulation is verified by experiments.

Key words: materials synthesis and processing technology, sheet hydroforming, inverse bulging effect, clearance between the punch and the blank holder, blank holder entrance radius
