Abstract

The invention discloses a rapid stamping hydraulic system. The rapid stamping hydraulic system comprises a power oil tank, a prefill valve, a main oil cylinder, a rapid oil cylinder, a sliding block,a return oil cylinder, a supporting energy accumulator, a control energy accumulator, a rapid control valve block, an auxiliary control valve, a main pump set, an auxiliary pump set, a pressure adjusting valve set, a first pressure sensor used for detecting the pressure of the main cylinder, a prefill oil tank and a second pressure sensor used for detecting the pressure of the rapid oil cylinder,wherein the main pump set is connected with the pressure adjusting valve set through a pipeline; the pressure adjusting valve set is connected with the main oil cylinder through a pipeline; the auxiliary pump set is connected with the control energy accumulator, the rapid control valve block and the auxiliary control valve through pipelines; the rapid control valve block is connected with the rapid oil cylinder through a pipeline; the rapid oil cylinder is connected with the sliding block; the supporting energy accumulator is connected with the return oil cylinder through a pipeline; the return oil cylinder is connected with the sliding block; the prefill oil tank is connected with the main oil cylinder through the prefill valve; and the main oil cylinder is connected with the sliding block.

Description

technical field [0001] The invention belongs to the technical field of forming hydraulic presses for automobile panels, in particular to a rapid stamping hydraulic system. Background technique [0002] Hydraulic presses are widely used in the field of stamping, as well as mechanical presses. Hydraulic presses have been unable to occupy most of the stamping machine market because of the huge difference between the working rhythm and the working rhythm of mechanical presses. [0003] The traditional hydraulic press system, whether it is the downstroke of the slider or the return stroke of the slider, is driven by the oil pump to move the slider. The specific process is as follows: the oil pump drives the oil into the cylinder, the oil entering the cylinder is continuously compressed, and the pressure of the oil rises to drive through the cylinder. slider action. In this process, the system needs to output signals through PLC, the signal drives the pilot solenoid valve to act,...
