Abstract
AbstractThe use of hook hood lock auxiliary catch is vital to all automotive cars. This paper deals with the design, development and analysis of new hook hood lock auxiliary catch and design the press tool to reduce number of stages of operations to manufacture hook hood component. The study of existing hook hood lock auxiliary catch revealed that there was development of potential crack on hook side and to overcome this, new hook hood auxiliary catch was designed with embossed profile located on the center of hook side and bend leg side. Stress analysis was performed, results revealed that new hook hood design had no potential cracks and was able to with stand higher stress value of 7–17 MPa. In design of press one stage of operation was reduced. Misalignment in embossed profile was 200 microns and was reduced to 20 microns. Further press tool can be analyzed for nonlinear and fatigue analysis.KeywordsPress toolEmbossingPotential crack
