| The global drive toward intermediate technology and sustainable development motivated the development of sheet metal rolling machines for small-scale artisanal manufacturers. This paper presents the design, construction and evaluation of a sheet metal rolling machine for small-scale enterprises. The machine consists of three rollers; a rigid forming roller, a free floating roller and a drive roller arranged triangularly with two handles for shape-rolling. The rollers were made of galvanized metal pipe, 1,050 mm long, 76 mm diameter, each approximately, 3 mm thickness; a driving shaft 1,220 mm long, 16.6 mm diameter and 4 pieces of mild steel washers to provide support to shaft and also to limit the bending stress on the rollers. The entire system is... |
