Abstract

The invention provides a valve hydraulic system. The valve hydraulic system comprises an electromagnetic main valve, a speed monitoring module, an overload protection module and a testing module, wherein the electromagnetic main valve is connected with an executing mechanism, an unloading valve is arranged on a bypass of the electromagnetic main valve, the unloading valve is used for unloading hydraulic oil in an emergency state, the electromagnetic main valve is independently connected with the speed monitoring module and the overload protection module, the speed monitoring module is connected with a speed protection switch, the overload protection module is connected with an overload protection switch, and the test module is connected with a test protection switch. According to the valvehydraulic system, when forging and pressing work is conducted, the high forging and pressing quality is achieved, the forging and pressing efficiency can be improved, and finally, accurate matching with a manipulator in time is achieved, so that errors of forged and pressed parts caused by the fact that the forged and pressed parts are not in place are avoided, and the quality is improved; and maintenance personnel can be guided to overhaul the designated position, the maintenance speed is increased, the downtime of forging and pressing equipment is shortened, and the productivity of the forging and pressing equipment is increased.

Description

technical field [0001] The invention relates to the technical field of forging machinery, in particular to a valve hydraulic system. Background technique [0002] Forging is the way to deal with the internal stress of metal in the manufacture of steel and metal. The development of modern industry has made the development of hydraulic pressure faster and faster, and the pressure of forging and the efficiency of forging have been continuously improved. There will also be Corresponding problems, such as forging requires high pressure, whether the pressure control meets the predetermined value of forging, and whether the speed of forging can be matched with the speed of the workpiece is an important indicator that affects the quality and processing efficiency of forging parts. The current forging press system only has an emergency stop system. Whether the emergency stop is effective and the final implementation of the emergency stop can only be determined according to the condit...
