Design and Development of Roller Machine

The global drive toward intermediate technology and sustainable development motivated the development of sheet metal rolling machines for small scale artisanal manufacturers. The entire system is mounted on a metal frame made from angled-iron bars which were secured in place with 19 mm bolt and nuts. The clamping and folding bearing blocks are 120 mm thick, the throat width is 1,200 mm, and maximum length capacity of the machine is 1,050 mm. The best roller aperture for material tested is 5.5 mm and maximum bend radius of 2.5 mm. The roller diameter is 22 mm, bottom roller center distance is 45 mm and yield strength and thickness of sheet is 205 Mpa, 1.5 mm. This paper presents the design, fabrication and evaluation of a sheet metal rolling machine for small-scale enterprises. This is used for performing the multiple operations like drilling bending threading and rolling. It was reduce the floor surface area and reduce material handling time and increase production efficiency. Fifteen percent of the welders and 40% of tinsmiths are well acquainted with the functions of the machine. A total of 73.53% (n=26) of the respondents are not acquainted (technology awareness) with the shape rolling technology while 26.47% (n=9) have a fair knowledge of the use of such machines in metal rolling. The whole machine has a very small footprint, making it ideal for the home workshop and small factory alike.
