Title

Metallic Scrap Processing with Bar Untangling Machine Designing

Abstract

Worldwide, construction and demolition waste is becoming a threat for many environmental problems. Construction and demolition waste frequently makes up 10 to 30 percentage of the waste dump at many landfill sites around the world. Metal bars form demolition sites are usually collected and sent to scrap sites where it is melted down and turned back into new reinforcing bar. Reuse of metal bars is better option than recycling. There are machines developed by various industries to straighten drawn and coiled metal bars, but the commercial bars available in the market have differing cross section and material properties. Nowadays straightening of these commercial bars are done manually in industries by hammering process. It is a very tedious job and time consuming too. So there is an industrial necessity to automate the process. In metal bar straightening method metal bar is straightened by transporting the metal bar between a pair of fixed and adjustable rollers. After conducting the straightening process for MS bars of 10mm diameter, a precision of was achieved. Autorotation of bar was prevented using the three roller standstill locking mechanism. Using ANSYS software for analysis, it was found that during the straightening process the bar undergoes maximum deformation at the centre portion whose value was within the allowable range for the combination of four fixed and three adjustable rollers. The stress developed in the bar was well within the permissible limits for steel material. The results show that the propose mechanism of straightening system is feasible and it provides favourable theoretical foundation for the development of commercial bar straightening machine. Reuse of metal bars generated from construction and demolition waste after straightening can also reduce the need for new landfills and that can also conserve the landfill space hence, proposed mechanism is also environment friendly.

Key Words

Standstill locking mechanism, autorotation, springback effect, elastoplasticity, elastic recovery torque
