Abstract

The invention relates to a full-automatic plate shearing machine hydraulic system on the basis of PLC (Programmable Logic Controller) control and belongs to the field of plate shearing machine hydraulic systems. The full-automatic plate shearing machine hydraulic system mainly comprises the same first and second shearing cylinders, two same pressing cylinders, a hydraulic control system of the shearing cylinders and the pressing cylinders, and a PLC control system; the hydraulic control system of the shearing cylinders and the pressing cylinders comprises an oil tank, a hydraulic pump, a motor, a one-way valve, a first pressure gauge, a second pressure gauge, a pilot overflow valve, a two-position two-way electromagnetic valve, an energy accumulator, a pressure reducing valve, a travel switch, an overflow valve, a two-position four-way electromagnetic valve and a double hydraulic control one-way valve. According to the invention, the PLC control system is adopted to implement accurate control of the system; the full-automatic plate shearing machine hydraulic system is provided with the non-contact travel switch accurately controlled by the PLC control system, so that a sheet metal is more accurately positioned and quality of the sheared sheet metal is higher.

Description

technical field [0001] The invention belongs to the field of shearing machine hydraulic systems, in particular to a full-automatic shearing machine hydraulic system based on PLC control. Background technique [0002] With the development of industry, the degree of automation of mechanical products is getting higher and higher. At the same time, the pollution of the environment is becoming more and more serious, and the requirements for energy saving and emission reduction are also getting higher and higher. Both of these have brought new challenges to the design of mechanical products. requirements and orientation. At present, the automation of large-scale shearing machines is low, and most of them adopt manual control and semi-automatic control. The production efficiency is low, and the energy consumption is relatively large, and the pollution to the environment is relatively serious. At the same time, the quality of sheared plates is not high. Meet the general quality re...
