This paper presents concepts for shock and vibration reduction of a forging tongs. In the forging industry, hand-operated forging tongs are often used for the machining of forged parts. Here, the employees are exposed to high loads from shocks and vibrations of the forming machines. A simulation model that has been created evaluates concepts for reducing the shocks and vibrations during forging

Handling hot steel parts weighing several kilos is physically demanding. A new type of forging tongs is designed to reduce stress at work, prevent pain and reduce sick leave.

Bulk-formed components are used in many applications in automotive and plant engineering. The conditions under which the components are manufactured, often at more than 800°C and thousands of tons of forming force, lead to high die wear. One way to reduce wear is to use suitable protective coatings. Initial basic investigations showed that the use of hard Diamond-like Carbon (DLC) wear-resistant coatings can significantly reduce the tribological effects on the die surface. With new methods such as the use of multilayer layer coatings and temperature measurement on the die surface by use of thin layer sensors, the potential of wear protection for semi-hot massive forming is to be investigated and expanded.
