A servo motor driven high performance energy-saving double acting hydraulic press is called servo hydraulic press.
  Rapid filling and direction of ordinary hydraulic machine in the control loop, but the controllable hydraulic source and quantitative AC servo motor oil pump. Instead of controllable hydraulic source ordinary induction motor drive, combined with a variety of sensors, through the regulation of motor control, to achieve energy saving, pressure, position and speed control system;
  A displacement sensor is added to the master cylinder and the auxiliary cylinder, and a pressure sensor is added to the main cylinder inlet circuit to realize closed loop control of position, speed and pressure;
  A proportional relief valve is added to the auxiliary cylinder outlet to realize the variable pressure margin force of the auxiliary cylinder. The motor is a high power AC servo motor, the motor is connected with the controller, and the flow rate is controlled by controlling the speed of the motor, and the volume speed regulation and voltage regulation of the main oil circuit are realized.
  Making full use of high power AC servo motor has the advantages of high efficiency, controllable, adjustable and good reliability. It can optimize the process parameters, improve the performance of hydraulic press and reduce energy consumption.
  The utility model relates to a high performance hydraulic press in the equipment field, in particular to a servo motor driven high-performance energy-saving double action hydraulic press, belonging to the innovative technology of the hydraulic press.
  Hydraulic press is an important equipment, which is driven by an electric motor to produce a high pressure liquid, and produces a straight line movement through the hydraulic cylinder. Because of the wide adaptability of hydraulic press, it is widely used in the forming of metal and nonmetal. The application of high power AC servo motor to hydraulic press instead of ordinary induction motor can simplify the structure of hydraulic system, improve performance and save energy.
  Due to the high power AC servo motor used in hydraulic machine, replace the structure of common induction motor, make full use of high power AC servo motor has the advantages of high efficiency, controllable and advantages of adjustable and good reliability, which can simplify the structure of the hydraulic system, hydraulic machine to save energy, improve performance, overcome a series of shortcomings of traditional hydraulic machine. The quick oil circuit and direction control of the ordinary hydraulic press are reserved, and the displacement sensor of master cylinder, pressure sensor, master cylinder and auxiliary cylinder is added. Not only can realize the ordinary hydraulic master cylinder down fast, slow return, working stroke, pressure, rapid return and auxiliary cylinder upward and downward working mode, and the working stroke of the master cylinder speed and pressure can be real-time control;
  Variable pressure floating edge can be realized. Full use of servo motor can be frequently started, variable speed characteristics, servo control, thereby improving the performance of hydraulic press and reduce energy consumption, so that hydraulic press work performance improved. Realize volume speed regulation, cancel standby evacuation, greatly reduce energy consumption.
  Servo hydraulic press is a kind of high performance and energy-saving double acting hydraulic motor driven by servo motors with good design, good performance and convenience.
