Abstract

The invention discloses a gate-type shearing machine hydraulic control system with a solenoid valve, which includes an oil tank, a buffer oil cylinder connected with an upper knife rest, an oil cylinder, a pressure plug-in, and a pressure-regulating control cover for fixing the pressure plug-in Plate, and the first cartridge valve composed of a solenoid valve for controlling and adjusting the pressure plug-in, and the second cartridge valve composed of a direction plug-in and a direction control cover plate for fixing the direction plug-in; the present invention utilizes a solenoid valve to realize gate type The hydraulic control system of the shearing machine realizes no impact when the tool holder stops at the same time, reliable and stable work, simple principle, easy to find when maintenance, saves time and effort, convenient maintenance, less heat and low noise during use; strong anti-pollution ability, The liquid flow resistance is small and the service life is long.

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...
