In this paper, the experimental setup of cold extrusion processing with electro-hydraulic chattering was developed and the working principle was described. This paper selects a kind of cup part as the research object, using the software Deform-3D to build a FE model, the velocity fields and the metal flow net were revealed during the extrusion processing. The changes of metal flow line with and without electro-hydraulic chattering were discussed with the help of SEM and Keyence super-depth three-dimensional microscopic system. ·Ò룺½¨Á¢µçÒº²üÕñƽ̨²¢¼òÊöÆä¹¤×÷ÔÀí£¬ÒÔÌ×±ÀàÁã¼þΪÑо¿¶ÔÏó£¬ÔËÓÃDEFORM-3D·ÂÕæÈí¼þ½¨Á¢ÓÐÏÞԪģÐÍ£¬Ä£Ä⼷ѹ¹ý³ÌÖеÄËٶȳ¡£¬Íø¸ñÁ÷Ïß,£¬²ÉÓÃɨÃèµç¾µ¡¢»ù¶÷Ê¿³¬¾°ÉîÈýάÏÔ΢ϵͳ¶Ô±È·ÖÎöÁË´«Í³¼·Ñ¹ºÍ²üÕñ¼·Ñ¹ÏÂÊÔÑùÈý¸öÇøÓòµÄ½ðÊôÁ÷Ï߱仯¡£ |
