Hydraulic rolling press machine for annular workpiece

The invention discloses a hydraulic rolling press machine for an annular workpiece. The hydraulic rolling press machine comprises a base, a vertical guide pressure device used for pressing the workpiece is arranged on the base, and comprises two vertical guide plates, one end of each vertical guide plate is hinged to the base, a beam is connected between the two vertical guide plates in a sliding manner, and a pressing device used for compressing the workpiece is arranged on the beam. Through adjustment of tensioning force and positioning of the width of a guide ring surrounding plate, efficiency is improved, a hydraulic cylinder compresses a positioning wheel to achieve accurate positioning, manpower is replaced, labor intensity is reduced, and meanwhile, potential safety hazards are removed. 本发明公开了环形工件液压滚动压力机，包括底座，底座上设有用于压紧工件的垂直导向压力装置；垂直导向压力装置包括两根垂直导向板，垂直导向板的端与底座铰接，两根垂直导向板之间滑动连接有横梁，横梁上设有用于压紧工的压紧装置。通过调整拉紧力以及导环围板宽度的定位从而提升效率，且采用液压缸压紧定位轮进行准确定位，取代了人力，降低了劳动强度同时消除了安全隐患。
