!�p4w Forging techniques are useful for working metal because they enable the desired shape to be given to the steel and also improve its structure, especially because they refine its grain size. It focuses on the basics, and includes classic procedures of the craft like punching and bending, as well as modern processes such as plasma cutting, heating with a blowtorch, or the use of manual power tools. Closed Die Forging. The rotating rolls draw the slab into the gap and compresses it. Most forging is done as hot work, at temperatures up to 2300 degrees F, however, a variation of impression die forging is cold forging. Forging techniques are used for the process design, die design and die manufacturing. With pictures and drawings in every tutorial showing how hot iron is shaped.

Tang: . Blacksmiths, mainly over the past 3000 years, have invented various techniques to work the material in different ways. Forging Forging is a basic process in which the work piece is shaped by compressive forces applied through various dies and tooling. Gyratory forging machine (GFM) is a precision forging process that produces cylindrical bar shapes by hot forging while the bar is rotating. Eng. Modern metalworking facilities have a variety of types of equipment to use in the process, and there are four common mechanized metalworking techniques: drop, press, roll, and cold forging. Graphic Human Machine Interface (HMI) capability allows operators to see how a forging press is functioning, and speeds local/remote diagnostics and troubleshooting.
