Abstract

The invention belongs to the technical field of a hydraulic press, and relates to a multi-group tonnage classification control system of a hydraulic press. The system comprises multiple classification tonnage groups, an oil tank and a connection oil pipe; and a proportional overflow valve is also arranged between the oil tank and the classification tonnage groups, wherein one classification tonnage group is directly connected to the proportional overflow valve through the connection oil pipe, and an electromagnetic valve is also arranged between the other classification tonnage groups and the proportional overflow valve. The multi-group tonnage classification control system of the hydraulic press, provided by the invention, can randomly select different tonnage combinations for work according to different lengths and processes of the processed workpieces, greatly lowers the processing cost, saves financial and material resources to some degree, and realizes compression moulding of complicated workpieces easily.

Description

technical field [0001] The invention belongs to the technical field of hydraulic machines, and in particular relates to a multi-group tonnage grading control system for a hydraulic machine in which multiple groups of tonnage grading are combined to work. Background technique [0002] At present, hydraulic presses used in the automotive industry have various forms according to the pressing process requirements. The car chassis is an important car part that supports and installs the car engine and its components and assemblies to form the overall shape of the car, and receives the power of the engine to make the car move and ensure normal driving. Automobile longitudinal beam hydraulic press, which can realize functions such as stretching, bending and shaping of U-shaped longitudinal beams. The automobile longitudinal beam pressed by this press is obtained by pressing, stretching, bending and finally shaping the punched plate with a thickness of about 8mm, a width of 400mm, a...
