The basic aim of ‘Portable Ramming Machine by Using Electrically Operated Ram for Sand Molding’ project is to achieve ramming operation with reduced human effort. In this context, we are in the process of designing & fabrication of Portable ramming machine which is operated by means of crank. The crank is the machine elements driven by the pulleys, which in turn are driven by the electric motor. The principle components of machine are hammer, crank, pulley, belt, shaft, bearings, bushes, motor and supporting structure. In the ramming machine, the crank serves the purpose of lifting the hammer and it also drops it from considerable height to impart the energy required for ramming. As a result hammer exerts very high potential energy under gravity over the sand mould to achieve required hardness. The Ram is used for ramming the sand uniformly around the pattern. It can be used even in small scale industries. To operate this Ram an Electric motor is needed. This Ram is handled by an operator just by moving it over the molding sand. The butt rams the sand at places moved and the sand is uniformly rammed. This Ram reduces the ramming time and labor. Due to this the cost is reduced considerably. So this machine finds application in foundries for small units.
