forjamento livre é principalmente o uso de força de impacto ou pressão para deformar o metal entre dois ferros opostos, a fim de obter a forma e o tamanho desejados do forjamento. Existem dois tipos de forjamento livre: forjamento livre manual e forjamento livre de máquina.

As ferramentas usadas para forjamento livre são simples, com duas ferramentas de processamento comumente usadas: martelos de forjamento e prensas hidráulicas. Elas têm uma ampla gama de aplicações e podem forjar forjados variando de menos de 1 kg a 300 t. Elas podem ser usadas para processar vários tipos de forjados, como forjados de eixo, forjados de anel, forjados de Virabrequim e forjados de dobra.

forjamento

1、 Free forjamento hammer

The tonnage of various specifications and models of free forjamento hammers is mainly expressed by the mass of the falling parts (including the upper anvil, hammer head, and working cylinder piston). Free forjamento hammers mainly include air hammers and steam air free forjamento hammers, which can generate impact force to deform metal and forge it into forjamentos. The tonnage of an air hammer is generally 50-1000 kilograms. The tonnage of steam air free forjamento hammers ranges from 1 to 10 tons.

2、 Prensa hidráulica

The tonnage of a hydraulic press is generally 5-150MN, expressed in terms of the large pressure it can generate. Metal is deformed by static pressure. The speed of the hammer head of the hydraulic press forjamento hammer can reach 7-8m/s, which is conducive to improving the malleability of the material and easily achieving a large forjamento depth; Working under static pressure, without vibration, with low deformation speed (the anvil speed of the hydraulic press is about 0.1-0.3m/s).

forjamento

The hydraulic press has a slower pressing speed and applies a non impact static pressure to the billet, so there is no need for a bulky anvil. Its tonnage is represented by the large pressure generated. During work, there is minimal vibration and noise. Due to the static pressure applied for a long time, the recrystallization time is sufficient, making it easy to forge the billet through. As a result, the resistance of the entire metal section is uniform, dense, and the mechanical properties of the forjamento are high.
