锻造生产信息推荐 圣霖国际优质服务

锻造工艺过程一般由以下工序组成，即选取优质钢坯下料、加热、成形、锻后冷却。锻造的工艺方法有自由锻、模锻和胎膜锻。生产时，按锻件质量的大小，生产批量的多少选择不同的锻造方法。

The forging process is generally of the following processes, namely, the selection of high quality billets, heating, forming and cooling after forging. The forging process includes free forging, die forging and fetal membrane forging. When manufacturing, according to the size of forgings and the number of production batches, different forging methods are chosen.

自由锻造是靠人工操作来控制锻件的形状和尺寸的，所以锻件精度低，加工余量大，劳动强度大，生产率也不高，因此它主要应用于单件、小批量生产。

Free forging is by manual operation to the shape and size of the forgings, so the precision of the forgings is low, the processing allowance is large, the labor intensity is big, and the productivity is not high. Therefore, it is mainly used in single piece and ***all batch production.

自由锻造分手工自由锻和机器自由锻。手工自由锻生产效率低，劳动强度大，仅用于修配或简单、小型、小批锻件的生产。

Manual free forging is inefficient and labor intensive. It is only used for the production of repair or simple, ***all and ***all forgings.Free forging c***ists of manual free forging and machine free forging.
