摘要
Abstract
Molten metal die forging(MMDF)processes is an advanced process for high-performance forming of aluminum alloy parts,MMDF technology is applied to the forming of closed subframes,fo-cusing on the performance uniformity of MMDF process scheme and MMDF subframe in this paper.Simulation studies show that single-runner MMDF has fewer confluence positions,higher surface quality and higher process yield than MMDF solutions with auxiliary runners.Trial production proves that the single runner liquid forging of A 356.2 aluminum alloy subframe can be obtained by using the HVSC2500T horizontal MMDF machine designed and manufactured by Guangzhou Hede,and the sampling tensile strength of the body can reach 320 MPa while the elongation is 11.12%.However,slag inclusion defects are prevalent in locations away from the sprue and where there is a confluence,and the strength and plasticity are low.关键词
