Technical scheme of hydraulic drive system of large tonnage inertial friction welder


A large tonnage inertial friction welding machine hydraulic drive system, including low pressure large flow blade pump (4), high pressure small flow plunger pump (7), the first two-bit four-hydraulic reversing valve (13.1), the second two-bit four-hydraulic reversing valve (13.2), three-bit four-hydraulic reversing valve (14), the third two-channel four-hydraulic reversing valve (16), spindle workpiece cylinder (18.1), tail seat workpiece cylinder (18.2) and top forging cylinder (18.3). The utility model patent technology greatly reduces the installed power, save energy consumption; but also realizes the spindle workpiece cylinder fast action and tightening, fast action and tightening, low pressure forward, high pressure work, high pressure fast forging and low pressure fast backward, system action process is automatically controlled by computer + PLC program, has the advantages of simple structure principle, stable and reliable action.
