Abstract

The invention discloses a hydraulic buffering system. The hydraulic buffering system comprises an oil tank, a hydraulic cylinder suitable for receiving external action force, a main pump unit in hydraulic coupling with the hydraulic cylinder, an auxiliary pump unit, energy accumulators, and a hydraulic motor, wherein the auxiliary pump unit is in hydraulic coupling with the hydraulic cylinder and used for making the hydraulic cylinder be in an initial position to get ready for receiving the external action force when the hydraulic buffering system is started; the energy accumulators are in hydraulic connection with the main pump unit as well as with the auxiliary pump unit and used for accumulating hydraulic oil pressurized by the main pump unit and the auxiliary pump unit; the hydraulic motor is in drive connection with the main pump unit and in hydraulic coupling with the hydraulic cylinder, and when the hydraulic oil in the hydraulic cylinder is squeezed to flow through the hydraulic motor due to the external action force, the hydraulic motor is driven to drive the main pump unit to rotate to fill the energy accumulators. The invention further discloses equipment comprising the hydraulic buffering system. The hydraulic buffering system is high in energy utilization efficiency and capable of reducing the operation cost at the same time.

Description

technical field [0001] The invention relates to a hydraulic buffer system and a device including the hydraulic buffer system. Background technique [0002] The hydraulic buffer system has been widely used in various industrial fields, especially when used in conjunction with the stamping unit, it can give full play to the characteristics of the hydraulic system. [0003] figure 1 It shows a hydraulic schematic diagram of a typical hydraulic buffer system 2 used in conjunction with a stamping unit 1 in the prior art, and the hydraulic buffer system 2 includes: a hydraulic cylinder 3, a proportional valve 4, an accumulator 5, and a main pump unit 6 , filter and cooling unit 7, oil tank 8 and motion and force controller 9. [0004] The working process of the hydraulic buffer system 2 is as follows: [0005] 1) In the initial state, the piston rod 10 of the hydraulic cylinder 3 is lifted to a desired height by means of the main pump unit 6; [0006] 2) State 1: During the st...
