Title:
伝動効率が高い自由鍛造油圧機及びその作動方法
Document Type and Number:
Japanese Patent JP6764016
Kind Code:
B2
Abstract:
The present disclosure relates to a high-efficiency transmission free forging hydraulic press and an operation method thereof. The high-efficiency transmission free forging hydraulic press comprises: a hydraulic cylinder, a hydraulic pump, and a pressurization energy storage apparatus. By providing two pressurization energy storage apparatuses between the hydraulic pump and the hydraulic cylinder of the high-efficiency transmission free forging hydraulic press, under the effect of a control system, the two pressurization energy storage apparatuses can alternately provide isobaric pressure oil or pressure oil having undergone pressurization to the hydraulic cylinder of the free forging hydraulic press, such that when the hydraulic pump operates in a status with a relatively low pressure, the hydraulic cylinder in the free forging hydraulic press can constantly obtain the isobaric pressure oil or the pressurization pressure oil, achieving the object of storage of surplus energy and high-efficiency transmission of the hydraulic press. The high-efficiency transmission free forging hydraulic press is reasonable in resource configuration, simple in provision structure, good in pressurization effect, and energy-saving and consumption-reducing.
