Tailored Blanks manufacturing technology in the automotive industry can not only reduce production costs , reduce vehicle weight , reduce fuel consumption and improve vehicle performance , you can also get high quality products . Therefore , the application of tailor welded blanks stamping parts for automobile manufacturers bring considerable economic and social benefits . Tailor welded blank forming process is still facing welding and stamping forming both the technical problems , especially in the stamping when plate thickness uneven or material is not at the same time will cause the sheet inhomogeneous deformation , making the stamping of tailor welded blanks pieces of quality was severely affected, thus affecting the quality of automotive body . Tailored Blanks in the automotive industry , bending pieces of the application is very broad , and therefore , the study Tailored Blanks bending mechanism to grasp the impact of the rebound and weld mobile Tailored Blanks bending accuracy , reasonable Tailored Blanks stamping process develop important. Tailored Blanks hat -shaped pieces , bending the main factors affect the cap -shaped pieces of Tailored Blanks bending rebound and weld move through theoretical analysis and experimental research study . Establish a horizontal transverse TWB the TWB cap shaped member bending model obtained the TWB cap shaped member bending force , the relationship between the bending stroke , and bending springback theoretical calculation formula , and the theoretical calculation formula and experimental data ; bending mechanism as well as rebound and weld torsion factors affect longitudinal Tailored Blanks hat-shaped bending analysis of longitudinal Tailored Blanks hat -shaped pieces ; cap -shaped horizontal Tailored Blanks bending experiments , analysis of the BHF, friction and mold size bending force , rebound and weld mobile . Article BHF , convex , die radius and lubrication methods and other factors using orthogonal test method , its combination of optimization. Intelligent control of the bending of the cap -shaped pieces of Tailored Blanks laid the foundation for further research .
