Description
Excerpt from Forging Operations
1. In its broadest sense, machine forging is the working of metal, either hot or cold, by means of a machine, causing it to flow in such a way as to give it some desired shape, either by slowly applied pressure or by blows. It is impossible to exclude from this machine process of working metals any forming operations on cold metals, as it has been found advantageous to forge metals at temperatures varying from ordinary atmospheric temperature to about 2,000° F. Low-carbon steel, certain brass alloys, and aluminum are frequently pressed, rolled, or punched cold. Zinc is most easily worked at a temperature of between 300° and 400° F. Aluminum can be drop-forged at a temperature slightly below a dull red heat, but it is very difficult to maintain it at exactly the required temperature. Copper can be forged hot, and pure annealed copper can be formed cold by pressing. From this it will be seen that machine forging operations are exceedingly varied in their nature.
Forging machines roll, hammer, or press the metal into the desired shape, and most forging machines may use either plain or formed dies. The use of formed dies will be considered exclusively in this Section.
