The forging process is an important casting technology, which can produce many different shapes and sizes of metal products. There are several different methods and techniques for forging process, and this article will introduce some of the main methods.
Free forging
Free forging is hammering or pressing unconstrained pre-heated billets to create a variety of shapes. This method is used to produce low cost, high productivity and simple parts. The advantage of this method is that a large number of parts can be manufactured because it is very efficient and there is little waste of raw materials.
Die forging
Die forging is a method of making complex shaped parts and medium numbers of parts using molds with specific geometries. This method is more accurate for forging geometry and requires better surface quality. Die forging machine is often used to manufacture gear, clutch parts, etc.
Hydraulic forging
Hydraulic forging is a method of machining billets into the desired shape using hydraulic equipment. Because it can produce large shear stress and uniform pressure, it is widely used in the manufacture of ultra-large parts or high-strength parts.
Cold forging
Cold forging refers to the forging process carried out at room temperature and is suitable for the manufacture of sophisticated workpieces and denatured components. This method can reduce cold treatment, dip vulcanization, heat treatment and other processing processes, improve the quality and productivity.
Other forging methods
In addition to the above four forging processes, there are many other forging methods, such as tooth forging, rolling forging, twisting forging, rolling forging, tensile forging and so on. Each of these methods has its own application and needs to be selected according to the actual situation.
In summary, forging process is an important metal processing process, can produce different shapes of parts and components. In different application scenarios, different forging methods need to be used to achieve the best results. Therefore, manufacturers need to conduct technology selection and process design based on actual needs.
