Structural elements of automotive forgings

Equipment used for forgings and production, such as air hammers, steam hammers, friction presses, etc., generate impact forces during work. When the equipment is subjected to such an impact load, it is easy to be suddenly damaged (such as the sudden break of the piston rod of a forging hammer), resulting in serious injury accidents. Noise and vibration: Forging hammers inevitably produce low-frequency noise and vibration, but there may also be certain high-frequency components, and the sound pressure level is between 95 and 115 decibels. Exposure of employees to forging vibrations can lead to temperament and functional impairment, reduce work capacity, and affect safety.

Auto forging is a machining process. A forging is an object of metal to which pressure is applied by plastic deformation to shape a desired shape or an appropriate compressive force. This force is usually achieved by using a hammer or pressure. The forging process builds a refined grain structure and improves the physical properties of the metal. In the actual use of the part, the correct design allows the particles to flow in the direction of the main pressure.

Forgings require that each piece be consistent, without any porosity, inclusions or other defects. Produced by this method, the ratio of strength to weight ratio is higher.

The advantages of forgings are extensible length, retractable length, extensible section, variable length, variable section.

Every forging needs to be the same, without any porosity, inclusions or other defects. This method produces elements with a higher strength-to-weight ratio. These elements are commonly used in aircraft structures.

The advantages of forgings are extensible length and retractable cross-section; retractable length, extensible cross-section; variable length, variable cross-section. Forgings are: free forging/hand forging, hot die forging/precision forging, upset forging, roll forging and die forging.
