Built-in electrode hot forming device and method based on blank shape optimization

The invention discloses a built-in electrode hot forming device and method based on blank shape optimization, provides the design that an electrode is embedded into the outer side surface of a female die opening chamfer, provides clamping pressure of the electrode and a blank through blank pressing force of a blank pressing ring, and can achieve rapid and uniform heating of a blank in a complex shape in a forming area. The initial shape optimization design of the formed blank can be met, then material flowing in the forming process is promoted, and the forming quality of the thin-wall component is improved. 本发明公开一种基于优化坯料形状的内置电极热成形装置及方法，提出采用电极内嵌至凹模口倒角外侧表面的设计，通过压边圈的压边力提供电极与坯料的夹持压力，本发明可以实现复杂形状坯料在成形区的快速均匀加热，可以满足成形坯料的初始形状优化设计，进而促进成形过程中的材料流动，提高薄壁构件的成形质量。
