低塑性拔长时，锻造，应注意选择合适的送进比，送进比太小时，变形集中在上下部，中心都锻不透，并沿轴向产生拉锻造应关于锻件的一些基本知识力，导致内部横向裂纹产生。在镦粗时，常用软衬垫镦粗或叠镦（用于锻薄饼形零件），以改善变形的不均匀性，防止产生表面裂纹。
When low plasticity is pulled out，锻造生产厂家， attention should be paid to selecting suitable delivery ratio， sending too much time， deformation on the upper and lower parts， and the center can not be built， and forging along the axial direction should be related to some basic knowledge of forging， resulting in the occurrence of internal transverse cracks. In the upsetting， commonly used soft liner (for upsetting or folding upsetting forging thin pancake，锻造报价， uneven parts) to improve the deformation， prevent the generation of cracks on the surface.
定期对设备进行保养，所有的操作者工作之前必须带好防护用具。在进行锻造作业时，几个操作者之间要集中精力，互相配合，躲开危险方向，选择相对安全的位置。
Maintenance of equipment on a regular basis， and all operators must take protective equipment before working. In the process of forging，圣霖锻造哪家好， several operators should their energy， cooperate with each other， avoid the dangerous direction， and choose a relatively safe.
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， displacement and welding etc.. Die forging is also divided into 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 small weight and large batches.
