Abstract

The invention relates to a servo hydraulic device and a servo hydraulic bending machine. Through the delicate design of the servo hydraulic device, a servo motor can drive a servo electric machine torun when a first electromagnetic valve and a second electromagnetic valve are opened simultaneously in order to drive an oil pump to pump out hydraulic oil in an oil tank, so that the hydraulic oil enters an upper chamber of an oil cylinder after flowing through a first oil circuit, the first electromagnetic valve, the first oil circuit and a second electromagnetic valve in sequence, and then thepressure intensity of the upper chamber is increased and a prefill valve is closed in order to realize slow-down motion or / and feeding motion of a piston device.

Description

technical field [0001] The present disclosure relates to a hydraulic bending machine, in particular to a servo hydraulic device and a servo hydraulic bending machine. Background technique [0002] Servo hydraulic bending machine, due to its relatively simple structure, large bending force range, easy maintenance and other characteristics, more and more are put into the production of sheet metal bending processing. However, during hydraulic bending, due to the poor rigidity of the servo hydraulic device in the servo hydraulic bending machine during force transmission, the mechanical positioning accuracy is poor. Contents of the invention [0003] The present disclosure provides a servo hydraulic device and a servo hydraulic bending machine to solve at least one of the above technical problems. The disclosed technical scheme is as follows: [0004] According to the first aspect of the embodiments of the present disclosure, there is provided a servo hydraulic device, includ...
