Di erent types of The types are: 1. The forging hammers are fixed at the end of the pneumatic cylinder piston rod. The solenoid valves are operated through the control unit. The pneumatic cylinder is operated through the pneumatic energy (air). Applying pressure for shaping the metal, the primary requirement always is to heat the metal to a definite temperature to bring in into the plastic state. It is similar to a compression test when the work part has a cylindrical cross-section and is compressed along its axis or its sides. The hammer is perfectly balanced, and weighs 2 pounds, perfect for a wide range of blacksmithing jobs. Surface cracking: this type of forging defects arises when the forging operation is performed at low temperature which leads to occurrence of cracks on the work pieces. The pressure applied is slow, steady and continuous in a single squeezing action in press forging. Forging is a manufacturing process involving the shaping of metal using localized compressive forces. Types of Forging Processes. Smith forging; Smith forging is the same which a village blacksmith uses for making various tools. These curves illustrate that, due to strain rate and temperature effects, for the same forging process, different forging loads and energies are required by dif-ferent machines.
