Forging Die Design Handbook

The art of forging die design requires a deep understanding of various terms and processes involved in this complex process. In this article, we will explore some of the key concepts that are essential for creating effective forgings.

One of the most important aspects of forging is lubrication, which can become carbonized on the surface of the forging, resulting in a condition known as 'EXTRUSION'. This can lead to poor quality forgings and affect their overall performance.

Another crucial aspect is the design of the die itself. A 'LOCKER' or preform die can be used when a part cannot be made in a single operation, allowing for more complex designs to be created.

Forging also involves various processes such as 'ROACH', which is a method of removing metal by planing it with a series of teeth moving in a straight line. This process is often used to achieve precise tolerances and surfaces finishes.

In addition to these processes, forging die design also relies on the properties of metals and alloys. For example, certain alloys can be 'AGE HARDENED' to increase their hardness and strength by precipitating particles of a phase from a supersaturated solid solution alloy.

Furthermore, understanding the different types of heat treatment is crucial in forgings. Annealing, for instance, involves heating or cooling at a temperature high enough to maintain solid solution, followed by rapid quenching to retain the supersaturated solid solution. This process can be used to soften cold-worked structures and relieve residual stress.

In conclusion, forging die design requires a comprehensive understanding of various terms, processes, and properties involved in this complex field. By grasping these concepts, engineers and designers can create high-quality forgings that meet exacting specifications.
