一种大型薄壁板材零件充液成形系统的开发

Design of sheet hydro forming press

充液成形技术具有许多优势,大型薄壁板材零件充液成形时具有成形压力低,液室容积大、排液时流量大的特点。目前主流的充液成形压力控制方式为采用增压系统控制液室压力,该压力控制方式受到单作用增压器的限制,具有容积小和起调压力高的局限。从大型薄壁板材零件充液成形特点入手,开发了一种大型薄壁板材零件充液成形系统,该充液成形系统弥补了单作用增压器的局限,起调压力低,通流量大,具有循环过滤功能,通用性强,非常适用航空航天类单件小批量生产。

Hydro forming technology has many advantages.According to the process characteristics of sheet hydro forming,discussed the difference between the special hydraulic press and the traditional hydraulic press,and its uniqueness.From the two aspects of the host structure and hydraulic system,designed a special hydraulic press for sheet hydro forming,especially for medium and small sized sheet hydro forming,the control system is excellent,and has broad market prospects.
