Abstract
The invention relates to a plate hydraulic shearing machine system. The plate hydraulic shearing machine system is characterized in that a quantitative hydraulic pump is directly connected with a pressure reducing valve, a pilot overflow valve and a two-position four-way electromagnetic reversing valve after being serially connected with a one-way valve, a pressure gauge is arranged between the one-way valve and the pilot overflow valve, and the pilot overflow valve is connected with a two-position two-way electromagnetic reversing valve; the pressure reducing valve is connected with the two-position four-way electromagnetic reversing valve, and a pressure gauge is arranged between the pressure reducing valve and the two-position four-way electromagnetic reversing valve; the two-position four-way electromagnetic reversing valve is directly connected with a scissors hydraulic cylinder or connected with the scissors hydraulic cylinder through a one-way sequence valve; the two-position four-way electromagnetic reversing valve is directly connected with a pressure block hydraulic cylinder and also connected with the pressure block hydraulic cylinder through a hydraulic-control sequence valve and a one-way throttling valve. The plate hydraulic shearing machine system is simple in structure, energy-saving, less in generated heat, safe and reliable.
