低塑性拔长时，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，圣霖国际锻造采购，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， attention should be paid to selecting suitable delivery ratio，圣霖国际锻造厂， 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，圣霖国际锻造报价， resulting in the occurrence of internal transverse cracks. In the upsetting， commonly used soft liner (for upsetting or folding upsetting forging thin pancake， uneven parts) to improve the deformation， prevent the generation of cracks on the surface.
锻造是一种利用锻压机械对金属坯料施加压力，使其产生塑性变形以获得具有一定机械性能、一定形状和尺寸锻件的加工方法，圣霖国际锻造，锻压（锻造与冲压）的两大组成部分之一。
Forging is a kind of forging process that uses pressure forming machinery to exert pressure on metal billet and make it produce plastic deformation to obtain certain processing methods of forging， which has certain mechanical properties， shape and size， and is one of the two components of forging， forging and stamping.
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.
