摘要
在对小型车轮结构特点分析的基础上,提出了轮类锻件模锻一次成形工艺;确定了模锻一次成形工艺方案,设计了成形、冲孔模具;并分析了影响金属流动充填模腔的有关因素,提出了改进措施。实践表明,采用该工艺成形的轮坯具有良好的内外在质量,这是一种适合多种结构轮型零件的成形工艺。
Based on the structure analysis on the wheel,concept of the closed-die forging one-step forming process has been put forward in the paper. The closed-die forging one-step forming scheme has been found out with the wheel forging dies and punching dies designed.The factors that affect the metal flow to fill the die impression has been analyzed ,and the improving measures have been proposed.By practical production,it shows that the wheels made by this technology are provided with excellent inner and surface quality and the closed-die forging one-step forming is a widely forming process for many kinds of wheel.
