锻件是金属被施加压力，通过塑性变形塑造要求的形状或合适的压缩力的物件。这种力量典型的通过使用铁锤或压力来实现。锻件过程建造了精致的颗粒结构，并改进了金属的物理属性。
A forged piece is an object that is applied to the metal by pressure to shape the required shape or the appropriate compression force by plastic deformation. This force is typically achieved by using a hammer or pressure. The process of forging has built a fine particle structure and improved the physical properties of the metal.
自由锻造是靠人工操作来控制锻件的形状和尺寸的，所以锻件精度低，加工余量大，劳动强度大，生产率也不高，因此它主要应用于单件、小批量生产。
Free forging is by manual operation to the shape and size of the forgings, so the precision of the forgings is low, the processing allowance is large, the labor intensity is big, and the productivity is not high. Therefore, it is mainly used in single piece and ***all batch production.
拔长
也称延伸，它是使坯料横断面积减小、长度增加的锻造工序。拔长常用于锻造杆、轴类零件。
自由锻造的基本工序包括镦粗、拔长、冲孔、弯曲、扭转、错移、切割及锻接等。
Pulling length
Also known as elongation, it is a forging process to reduce the cross-sectional area of the billet and increase the length. Pullout is often used in forging rods and shaft parts.
The basic processes of free forging include upsetting, drawing, punching, bending, torsion, offset, cutting and forging.
