Forming Characteristics

In recent several years, although production of magnesium has risen dramatically, production of magnesium alloy sheet remains still at a very low level in practical use. The major barrier to greatly increased magnesium alloy use has been in still primarily high manufacturing cost as well as poor work ability of wrought magnesium sheet alloys. One of the author has investigated in cold roll forming of magnesium alloy, however detailed forming characteristics of the wrought magnesium alloy sheets has not been clarified. The aim of the study is to confirm possibilities of practical use of wrought magnesium alloy by using told roll forming process. A three dimensional elasto-plastic analysis by finite element method (FEM) has been conducted to examine the shapes of cross section, spring back characteristics, bending strains and longitudinal membrane strain of magnesium alloy sheet and cold rolled steel sheet during forming.

Roll Forming Process

With deepening of roll forming technology and the proficiency of computer aided design and finite element Analysis (FEA) technology, it is widely noted that using the technology of FEA to simulate the roll forming process. In this paper, the current status of finite element simulation for roll forming process at home and abroad is summarized. And the finite element theories of deformation zone in roll forming process are analyzed. The new issues on roll forming process faced by finite element simulation, including advanced high strength steel (AHSS), multipass heterosexual cross section and coupling thermo-mechanical-metallurgical (TMM) coupling etc. are discussed. Moreover, the future trends of numerical simulation about the roll forming process are forecasted.

Roll Forming Process

Cold roll-forming of metal sections is a significant field in advancing forming of strip metal, and the forming processes are influenced by many factors. The scientific design of passes is worked out by combining theoretical analysis with finite element analysis, in accordance with the principles of cold roll-forming; thus the desired high-quality bending sections are achieved through a combination of theory and practice. This study mainly addresses the velocity of the rolls for sheets that have angle sides, and the spring-back of SGARC 440 alloy sheets in the roll forming process, where we use DEFORM to simulate the sheet.
