锻造生产加热设备和锻压设备不可少，这些设备释放大量热能，需要我们在通风净化环境中进行。锻造工具种类繁多，也是密集型作业，要求每个技术人员都不能马虎，坚守自己的岗位，嘈杂的环境需要冷静的技师，不能随意操作。
Forged production of heating equipment and forging equipment can not be less, these release a large amount of heat energy, we need to carry out in the ventilation and purification environment. There are various kinds of forging tools, which are also intensive operati***. Every technician is not allowed to be careless and stick to their. The noisy environment needs a cool technician and can not be arbitrarily operated.
机器锻造是自由锻造的主要方法，可锻造质量达到几百吨的大型锻件，这使得自由锻在重型机械制造中具有特别重要的作用。Nowmoreandmoreforgingsfactoriesaregoingtothemarket。例如，水轮机主轴、多拐曲轴、大型连杆、重要的齿轮零件，在工作时都承受很大的载荷，常采用自由锻造方法生产毛坯，使其具有很高的力学性能.满足使用要求。
Machine forging is the main method of free forging. It can forge large forgings with a quality of hundreds of t***, which makes free forging play a very role in he***y machinery manufacturing. For example, the main shaft of a hydraulic turbine, a multi crank crankshaft, a large connecting rod, and important gear parts are subjected to he***y loads when they are working. Free forging is often used to produce blanks, so that they h***e high mechanical properties.
镦粗主要有以下形式：
完全镦粗。完全镦粗是将坯料竖直放在砧面上， 在上砧的锤击下， 使坯料产生高度减小，横截面积增大的塑性变形。
Upsetting mainly includes the following forms:
Full upsetting. Complete upsetting is to place the blank vertically on the anvil surface, hammering on the anvil, so that the height of the blank decreases, the cross-sectional area increases plastic deformation.
