Abstract

The invention discloses a hydraulic control system with a gate type shearing machine with one electromagnetic valve; the hydraulic control system comprises an oil tank, a buffering oil cylinder and an oil cylinder; the buffering oil cylinder and the oil cylinder are connected with an upper tool rest; the hydraulic control system further comprises a first cartridge valve, composed of a pressure insert, a pressure-regulating control cover plate for fixing the pressure insert and an electromagnetic valve for controlling and regulating the pressure insert, as well as a direction insert and a direction control cover plate for fixing the direction insert; the hydraulic control system of the gate type shearing machine is realized by using one electromagnetic valve; meanwhile, no impact of the tool rest during pause is realized; and the hydraulic control system has the advantages of rational and stable working, simple principles, easy troubleshooting in maintenance, time-saving, labor-saving, convenient in maintenance, less heat and low noise in use, strong anti-pollution capacity, small liquid flow resistance and long service life.

Description

technical field [0001] The invention belongs to a hydraulic control system, and relates to a hydraulic control system of a gate shearing machine, in particular to a hydraulic control system of a gate shearing machine with an electromagnetic valve. Background technique [0002] At present, the gate-type shearing hydraulic system usually uses 6 to 10 solenoid valves to control the working conditions such as pressing of the presser foot, cutting and returning of the knife holder, etc. The hydraulic principle is relatively complicated and the cost is high. The gate-type shearing hydraulic system currently used The principle of the system is complicated, and four hydraulic valves are used to control the series cavity, or even more; too many solenoid valves are prone to failure, and when a failure occurs, it is difficult to troubleshoot and repair. Contents of the invention [0003] In order to solve the problem that there are too many electromagnetic valves in the existing gate...
