金属塑性成型是利用材料的塑性性质进行加工的一种方法。它把从冶炼得到的锭坯在高温或室温下通过轧辊或模具施加压力,使其形成一定形状的毛坯或零件。经过塑性加工后的金属,具有均匀致密的显微组织和合理的纤维方向,提高了材料的强度和韧度。对于重要的零件常利用塑性成型的方法来制造。在室温下进行冷态塑性成型能够得到高精度的零件,不仅减少或代替了切削加工,而且还节 Metal plastic forming is the use of plastic material properties of a method of processing. It obtained from the smelting billet at high temperature or room temperature by the pressure roller or mold to form a certain shape of the blank or parts. After plastic processing of the metal, with uniform and dense microstructure and reasonable direction of the fiber to improve the strength and toughness of the material. For the important parts often use plastic forming method to manufacture. Cold plastic forming at room temperature can produce high-precision parts, not only reduce or replace the cutting, but also section
