| Summary: | 碩士 === 國立虎尾科技大學 === 機械與電腦輔助工程系碩士班在職專班 === 107 === This research is for adjustable lifting desk stand, we use SPCD cold rolledsteel
steel thickness 1.5mm to study compound extension forming and mold design to decrease molding process and to increase precision. Firstly, we study traditional drawing process, it is about blank, drawing and trimming. Engineering software can simulate compound extension forming design (drawing + trimming) and according to different parameter, like material, gap , pressing force, radius and coefficient of friction to analyze the deforming, stress and crack.
The study shows it is a compound extension trimming mold design. The mold gap uses in drawing can trim the flange out. To combine two mold in one step, so it can decrease stamping process and cost. Furthermore, it can also increase production efficiency. As the simulation experiment, product dimension can achieve design requirement.
