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，圣霖国际锻造采购， 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，圣霖国际锻造生产， drawing， punching， bending， torsion， offset， cutting and forging.

自由锻的基本工序主要有镦粗、拔长、冲孔、切割、弯曲、扭转、错移及锻接等。模锻又分为开式模锻和闭式模锻．金属坯料在具有一定形状的锻模膛内受压变形而获得锻件，模锻一般用于生产重量不大、批量较大的零件。

The basic process of free forging are upsetting， stretching， punching， cutting， bending， torsion，圣霖国际锻造价格， displacement and welding etc.. Die forging is also divided i* open die forging and closed die forging. Metal billets are pressed and deformed to form forgings in the forging die chamber with a certain shape， and die forging is generally used for producing parts with *all weight and large batches.

自由锻造是利用冲击力或压力使金属在上下砧面间各个方向自由变形，不受任何限制而获得所需形状及尺寸和一定机械性能的锻件的一种加工方法，简称自由锻。

Free forging is a processing method of forging parts，圣霖国际锻造， which can make metal in all directi* of the anvil between the upper and lower anvil， and obtain the required shape and size and certain mechanical properties by the impact force or pressure， and the free forging is called free forging.
