Introduction
The forging process involves using dies or molds to press a metal into the desired shape, usually under great pressure. The sheer drive of a forging press, combined with precision tooling, creates the right metals for many applications. Forging presses can come in many different sizes and capacities, so it is important to determine the maximum size permissible for the forging machine in use. Specifically, this article will discuss the maximum size range for forging parts on a forging press machine.
Definition
The size range of a forging press, also known as a power hammer, indicates the maximum size of parts that can be made on the machine. It is distinguished from other metal working presses by its high force and capabilities to produce parts from difficult metal alloys, such as titanium and superalloys. According to the American Society for Testing and Materials (ASTM), forging presses are typically categorized by their capacity in “tons,” which actually refers to the amount of force that the machine is able to exert during the forging process. Depending on the size of the press and its related parts, the tonnage of a particular machine could range anywhere from 5 to 3500 tons.
Using a Forging Press
When using a forging press, it is important to choose the right size die or mold that is in accordance with the press’s size range. It is also important to choose the right material for the forging process according to the part’s intended purpose. Finally, it is essential to ensure that the press is operated properly and safely, as improper operation could lead to dangerous situations.
When forging parts, it is important to factor in a safety margin for the process, as the metal being used may be thicker and of a higher content than what is demanded in the final product. This process of providing a safety margin helps ensure that the part produced does not exceed the size range of the forging press.
Maximum Size for Forging Parts on a Forging Press Machine
When determining the size range for forging parts on a forging press machine, it should be noted that the size of the part is determined by the size of the die or mold that is used. Generally speaking, the die or mold used should not exceed 25 percent of the press tonnage, as going beyond this percentage could cause damage to the press or create parts that are of a lesser quality than what is desired. Therefore, if the tonnage of the press is 2000 tons, the size of the die or mold should not exceed 500 tons.
Conclusion
Forging parts is an important industrial process that requires the use of the right size presses and dies. It is important to understand the size range of a forging press and to stick within that maximum range in order to ensure quality parts are produced. Generally speaking, the size of the die or mold used should not exceed 25 percent of the press tonnage, as going beyond this percentage could cause damage to the press or create parts that are of a lesser quality than what is desired. This article discussed the maximum size range for forging parts on a forging press machine, and how to determine the right size press and die for a particular forgings job.
