Special titanium alloy forging, how to choose equipment?

Forging hammer

      Die forging on the die forging hammer is the earliest developed die forging method. Although various new die forging equipment and die forging process methods have emerged, the die forging on the forging hammer is flexible, adaptable, easy to fill the mold, can be single-die and multi-die, and the equipment is inexpensive. Advantages, therefore, it still plays an important role in the production of die forgings. However, die forging on forging hammers also has its insurmountable disadvantages, such as large noise and vibration, environmental pollution, and poor working conditions. Because of its high speed, it is not suitable for forging special alloys with low plasticity.

      The die forging hammer (including the hammer) starts to hit the forgings at a speed of 4m/s to 8m/s. It is an impact load. The hammer strike speed is high and the change is large. It is not suitable for forging special alloys with low plasticity and slow recrystallization speed. The special alloy which is not too bad in plasticity can also be forged on the die forging hammer and the counter hammer, but the heating temperature is different from that of the press die forging. In addition, the forging begins with a light hit, then gradually increases the hammering force and strictly controls the amount of deformation per hammer. The amount of deformation of the last hammer in the final forging process is particularly important to avoid uneven grain formation.
