The invention discloses an energy-saving type double-execution-unit hydraulic machine system and a control method. The energy-saving type double-execution-unit hydraulic machine system is characterized by comprising a machining system body and a positioning and oil supplementing system; the machining system body comprises execution units and a driving unit; each execution unit comprises two sets of single-piston-rod type piston cylinders which are the same in structure, and rod cavity oil openings communicate with each other through a throttle valve, so that complementary action of execution components of the hydraulic cylinders is achieved; when one piston cylinder execution mechanism descends, the other piston cylinder execution mechanism ascends, and vice versa; the energy efficiency and the working efficiency of a hydraulic machine can be effectively improved; and a positioning and oil supplementing loop of the hydraulic machine is used for adjusting the initial positions of the double execution units, thus, the relative position of the double execution units can be adjusted in the working process, and the system flexibility is improved. According to the energy-saving type double-execution-unit hydraulic machine system and the control method, the driving unit is shared by the double execution units, the matching degree of a load and the driving unit is improved, and the energy loss of the machining process is reduced.
Description
technical field [0001] The invention relates to a hydraulic press system, in particular to a double-executing-unit hydraulic press energy-saving system and a control method thereof, which are used to improve the working efficiency and energy efficiency of the hydraulic press. Background technique [0002] Forming processing is widely used for its advantages of high production efficiency, material saving and high processing quality. The hydraulic press has the advantages of stable transmission and simple control, and has become an important transmission form of forming equipment. [0003] However, due to the load characteristics and driving characteristics of hydroforming equipment, the energy loss of hydroforming equipment is high, and the efficiency is even as low as 50%. Among them, when the hydraulic press is working, the slider frequently rises and falls according to the working rhythm, and the gravitational potential energy and kinetic energy are converted into heat en...
