Process technolgy of hot forging
Hot forging presses use an electric heating system to heat a metal part, called a billet or workpiece, to about 75% of its melting temperature. The metal is then shaped using processes like hammering, pressing, or upsetting. The heat and strain rate cause the metal to deform and recrystallize simultaneously, which prevents strain hardening.
Average temperatures for hot forging includes
Aluminum (Al) Alloys - 360° (680°F) to 520°C (968°F)
Copper (Cu) Alloys - 700°C (1 292°F) - 800°C (1 472°F)
Steel – up to 1 150°C (2 102°F)
Factors to Consider During Hot Forging Process
As the name suggests, the process of hot forging requires the heating of the metal, so the heating temperature has a significant impact on the forming process and result. In order to ensure the forgability of the metal and obtain good internal structure performance, the forging heating must follow certain heating specifications and carry out the forging process within the specified temperature. At the same time, because the temperature of the blank metal is very high, sometimes the mold also needs preheating, so there are certain requirements for the life of the mold and forming equipment. In order to ensure the progress of the forging process, the following major issues need to be considered during hot forging process.
Features and advantages of hot forging press
The hydraulic system has automatic protection devices such as multi-level overload protection, oil temperature alarm, and oil level alarm protection. The electrical system adopts mature PLC control to ensure the safety of the equipment and operators. The pressing working cylinder adopts a large flow filling valve and auxiliary oil tank to supply liquid at the same time, which can realize rapid filling, replenishing, and oil return during lifting, effectively saving short-term auxiliary time and improving forging efficiency. The equipment is equipped with a reliable cooling circulation system, which can stably control the temperature rise and ensure the safe and reliable operation of the system.
