Abstract：
|
|
The drawing process of square cup using laser TWBs(tailored welding blanks) in different thicknesses and materials was studied using Dynaform,a professional software on sheet forming.The results show that the thickness difference of the two parts has significant influence on reasonable ranges of binder forces,forming limit and weld seam movement.When the proportion of the two parts(the position of weld seam) is changed,the larger the difference of proportions is,the less the forming limit will be,the more the proportion of the thinner part is,the more the weld seam movement will be.These above phenomenons were explained according to the stress and strain state of the two parts in forming process.
