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，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.
基本工序：自由锻造时，锻件的形状是通过一些基本变形工序将坯料逐步锻成的。自由锻造的基本工序有镦粗、拔长、冲孔、弯曲和切断等。
The basic process is: free forging, the shape of forging is gradually formed by some basic deformation processes. The basic process of free forging is upsetting, drawing, punching, bending and cutting.
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.
