"Manufacturing Of Sheet Metal Butt Strap In Single Piece Using Rubber Press Forming Process"
Abstract: Manufacturing of typical sheet metal butt strap (6) in single piece using rubber press forming process. In first stage of manufacturing process, flat pattern (7) routed by CNC router machine is pressed using rubber press tool (8, 9) and intermediated L shape profile (10) has been formed. In next stage, hatch marked area of intermediated L shape profile (10) has been removed by trimming process. This eliminates material wastage, production lead-time, contour deviations, warpage, distortion, localize residual thermal stresses, stress relieving and crack detection due to welding process. This also improve uniform thickness after press forming and maintaining homogeneity of material throughout. It also eliminate number of tools and welding fixture required to manufacture and·assemble different parts.
