【摘要】 尾板是压铸机合锁模机构中的关键零件,其刚度不仅关系到所加工零件的精度,而且直接影响到相关运动副乃至设备的寿命。为保证尾板在设计过程中的合理性,文中对某30000kN压铸机尾板满载荷条件下的力学行为进行分析。利用有限元法比较原始和减重两种设计方案的刚度以及应力等力学参量,根据计算结果对尾板加工制造中的要点给出相应的建议。整个分析结果表明,减重设计对尾板刚度将产生一定的影响,但目前的减重设计方案可以满足设计要求。更多还原

【Abstract】 Clamping moulding board is important component of die cast machine. The rigidity of the machine directly influences not only the precision of the product but also the life length of relative pairing elements and the whole machine. The deformation of clamping moulding board of large-scale magnesium die cast machine is analyzed by FES (finite element simulation) to guarantee the rationality of designing. The rigidity, stress and strain distribution of two different design scheme, with and without lightening hole, are compared and analyzed. According to the FES result, the two design scheme are evaluated and corresponding emphasis on manufacturing procedure are presented. FES result indicates that, the lightening hole on the second design scheme have some effects on the rigidity of solid plate, however its influence is not fatal, the second design scheme can also meets the design standard.更多还原
