[CN 201821448946.4] 100T Metal Packing Hydraulic Press Servo System
[CN 201821448946.4] 100T metal packing hydraulic press servo system title: 100T metal packing hydraulic press servo system application number: CN 201821448946.4 applicant: Hubei lidi machine tool co., ltd. application date: 2018-9-5 patent type: utility model the utility model discloses a 100T metal packing hydraulic press servo system, which includes a servo motor, the output shaft of the servo motor is connected with an internal gear pump, and the internal gear pump is connected with the hydraulic system of the metal packing hydraulic press, and provide hydraulic power to it; a pressure sensor for system pressure monitoring is installed on the pump port pressure oil circuit of the hydraulic system; the pressure sensor is connected to the signal input end of the PLC controller through an analog-to-digital converter, and the PLC controller The signal output end is connected to the servo motor through a servo driver. The PLC sends instructions to the servo driver to control the output flow and pressure of the electro-hydraulic servo system. In the operation of the system, the power loss is reduced in the state of no-load standby, pressure holding and pressure relief, and the energy saving effect is remarkable. At the same time, the stable and reliable operation of the system is ensured, the degree of automation of the system is improved, and the production cycle is shortened.
