Development of a Rivet Extractor

A manual rivet extractor was designed and fabricated to facilitate removal of blind rivets of sizes 4.0mm x 19mm and 4.8mm x 19mm from joints, machines and other structured assemblies without causing damages to joined components. The extractor parts were made up of mild steel. It had two head screw of 5mm and 4mm beak. It is a manually operated device that was readily be fabricated in simple workshop. Safety load of each head screw of 5mm and 4mm beak were calculated to be 120.69KN and 94.54KN respectively. The torques on them were 452.58Nm and 283.62Nm respectively. It is a robust and handy device that when operated carefully is expected to be useful for operator for a while.
