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， 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.
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，圣霖国际锻造价格，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， sending too much time，圣霖国际锻造， 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，圣霖国际锻造采购， uneven parts) to improve the deformation， prevent the generation of cracks on the surface.
选择好的锻件产品跟锻造工艺或者锻造厂家肯定是有关系的，现在有越来越多的锻件厂走向市场，对此，用户挑选锻件产品的难度就增加了。如果对锻件缺乏***的认识，圣霖国际锻造厂，那么，在选择的时候就会多很多顾忌。
The selection of good forging products is closely related to forging process or forging factories. Now more and more forgings factories are going to the market. Therefore， users" difficulty in selecting forgings is increasing. If the forgings are lack of professional knowledge， there will be a lot of scruples when choosing.
