金属塑性成形技术研究

The Study of Metal Plastic Forming Technology

金属塑性成形过程的选择和实施与材料,成形件的几何形状、过程的实施条件(压力、温度和速度等)密切相关。根据金属塑性变形的特点,在机械制造中常用锻造的方法来生产各类高强度、南韧度的毛坯或半成品,常用的锻造方法有自由锻、模锻和胎模锻造。本文介绍金属塑性成形中的自由锻造部分。

The option and practice of the metal plastic forming process are nearly related with the material ,geometric shape of the forming workpiece, the process＇ s implement condition （press, temperature and velocity etc, ）. According to the characteristic of the metal plastic forming,the forging is used in mechanical manufacturing to produce high intensity, high toughness roughcast or semi-manufactured goods, The forging methods are usually used for free forging, die forging and losse tooling forging, This paper introduces the free forging of metal plastic forming process.
