[CN 202010389775.8] Hydraulic automatic control system of hydraulic shearing machine tool
[CN 202010389775.8] Title of hydraulic automatic control system of hydraulic shearing machine tool: Application number of hydraulic automatic control system of hydraulic shearing machine tool: CN 202010389775.8 Applicant: Zhu Jiaqi Application Date: 2020-5-11 Patent Type: Application of Invention The present invention relates to the technical field of shearing machine tool, specifically a hydraulic automatic control system of hydraulic shearing machine tool, the hydraulic automatic control system includes a system overflow circuit, a series shear circuit and a decompression clamping circuit; the system overflow circuit includes an oil inlet filter connected to an oil tank, the oil inlet filter is sequentially connected to an oil pump through a pipeline And the first one-way valve, the pipelines of the oil pump and the first one-way valve are connected with the oil tank through a pilot relief valve, it enables it to change from fast to slow more smoothly, avoids violent oscillation during change, and prolongs the service life of hydraulic shearing machine tools and cutters. It can also ensure the overall synchronization through the series connection of shearing cylinders and the setting of compensation circuits, avoid the change of shearing angle caused by serious asynchronous tool holder, and further prolong the service life of shearing machine tools and cutters.
