复杂的冲压成形过程可以分解成为三个主要的变形成分:拉伸、延展及弯曲。纯粹由拉伸、延展或者弯曲构成的成形工序是不常见的。所以在复杂的冲压过程中零件所产生的变形就往往是由这三种成分共同作用所致。但是每种成分所占的比例却因零件而 Complicated stamping processes can be broken down into three major deformation components: stretch, stretch and bend. Forming processes that consist solely of stretching, stretching or bending are uncommon. Therefore, the complex parts of the stamping process deformation is often caused by the interaction of these three components. However, the proportion of each component is due to the parts
