Forging of workpieces and metal properties, forging

The size of the forged piece forging is favorable for mass production. Die forging, extrusion, stamping, etc. The size and stability of the mold is applied. High-efficiency forging machines and automatic forging lines can be used to organize specialized large-volume or mass production.
The forging process of forgings includes forging blanking before forming, forging billet heating and pretreatment; heat treatment, cleaning, correction and inspection of the workpiece after forming. Commonly used forging machines are forging hammers, hydraulic presses and mechanical presses. The hammer has a large impact speed, which is good for metal plastic flow, but it will produce vibration. The hydraulic machine is forged by static force, which is good for forging metal and improving the structure. It works smoothly, but the productivity is low. The mechanical press has a fixed stroke and is easy to mechanize. And automation.
Future forging process will improve the intrinsic quality of forgings, develop precision forging and precision stamping technology, develop forging equipment and forging production lines with higher productivity and automation, develop flexible forging forming systems, develop new forging materials and forging processing methods. development of

In addition, the forging member can change the metal structure when used, and improve the metal properties. After the ingot is hot forged, the original cast loose, pores, microcracks, etc. are compacted or welded; the original dendrites are broken to make the grains fine; at the same time, the original carbide segregation and unevenness are changed. Distribution, so that the organization is even, so that the internal compact, uniform, fine, comprehensive performance, reliable use of forgings. After the forging is deformed by hot forging, the metal is a fibrous structure; after cold forging deformation, the metal crystal is ordered.

A forging is a workpiece in which a metal is plastically flowed to form a desired shape. When the metal is plastically flowed by an external force, the volume does not change, and the metal always flows toward the portion of the resistance. In production, the shape of the workpiece is often controlled according to these rules, and deformations such as upsetting, reaming, bending, and drawing are realized.
