碩士 === 國立虎尾科技大學 === 機械設計工程研究所 === 101 === Flexible automatic hammer machine design that is simultaneously the impact of different cardboard types of automotive parts for all galvanized iron nails to reach all goal of punched. Major mechanisms including the positioning mechanism of the punch position of flexible adjustment to accommodate galvanized iron nails of different sizes and types distributed. Two-step punch mechanism can be suppress plastic sheet on cardboard and then impact all galvanized iron nails to achieve the adhesive on plastic sheet of plastic deformation. Automatic advance and retreat cardboard mechanism, PLC automatic control, operation interface, control the chain of strip cardboard acceleration and chain of forced tight value to achieve automatic strip cardboard moving, punch and unloading entire row of targets. Secondly use Deform 3D analysis in five kinds of punch impact surface geometry and offset of impact stress and deformation results. Experimental results show that when the punch impact surface is concave like V geometry, strip cardboard acceleration is 10 m⁄s^2 , and chain forced tight value is 6.00mm can be product yield 99%, reduction 10% of time-consuming,replace 50% of human resources . And is in good agreement with the results of the analysis, it can be proved the reliability of analysis.
