Abstract

The utility model relates to a double hydraulic cylinder synchronous control system of a gantry hydraulic press. According to the double hydraulic cylinder synchronous control system, grating rulers mounted in two hydraulic cylinders transmit movement stroke parameters of the two hydraulic cylinders to the corresponding control system in real time, and the control system ensures that the two hydraulic cylinders keep a synchronous motion state all the time by controlling corresponding flows of electronic flow control valves connected with the two hydraulic cylinders respectively. Compared with the existing conventional hydraulic control means, the system has the advantages of better synchronizing precision and lower failure rate.

Description

Portal shaped hydraulic press double hydraulic cylinder synchronous control system
Technical field
The utility model relates to hydraulic press, is specifically related to portal shaped hydraulic press double hydraulic cylinder synchronous control system, belongs to hydraulic machinery technical field.
Background technology
Well-known: portal shaped hydraulic press is to realize work object by moving up and down of walking beam, and moving up and down of walking beam is two Driven by Hydraulic Cylinder by being fixed in the frame of walking beam two ends, so, from structure and the working method feature of portal shaped hydraulic press, two hydraulic cylinders that are fixed in the frame of walking beam two ends must guarantee synchronous working in the time of work.
At present, although existing portal shaped hydraulic press is not quite similar in the technological means that keeps two hydraulic cylinder synchronous,, be all generally to realize by the means of hydraulic control, there is the defect that synchronization accuracy is poor, fault rate is higher.
Summary of the invention
The purpose of this utility model is: for the existing above-mentioned defect of existing portal shaped hydraulic press, the utility model provides a kind of novel portal shaped hydraulic press double hydraulic cylinder synchronous control system, overcomes two defects that hydraulic cylinder synchronous precision is poor, fault rate is higher of existing portal shaped hydraulic press.
The utility model is realized the technical scheme that above-mentioned purpose adopts: described portal shaped hydraulic press double hydraulic cylinder synchronous control system, it is by piston cylinder, grating scale, electronic flow control valve, total inflow pipeline, hydraulic flow control valve, total oil returning tube forms, it is characterized in that: the pressure chamber of two hydraulic cylinders is connected with total inflow pipeline by an electronic flow control valve respectively, the oil back chamber of two hydraulic cylinders is connected with total oil returning tube by a hydraulic flow control valve respectively, the piston rod centre of two described hydraulic cylinders is shaped with blind hole, crown center position at piston cylinder is mounted with grating scale, the bottom of described grating scale is deeply entered in the blind hole in piston rod centre.
Beneficial effect: in the utility model, be arranged on two grating scales in hydraulic cylinder the travel parameters of two hydraulic cylinders is passed to corresponding control system in real time, control system is by controlling the corresponding discharge of the electronic flow control valve being connected respectively with two hydraulic cylinders, guarantee that two hydraulic cylinders remain the state of being synchronized with the movement, so, can be found out by systematic schematic diagram of the present utility model and operation principle, compared with the means of the utility model and existing conventional hydraulic control, have synchronization accuracy better, fault rate lower advantage.
Accompanying drawing explanation
Accompanying drawing is principle schematic of the present utility model;
Shown in figure: 1, piston cylinder; 2, grating scale; 3, electronic flow control valve; 4, total inflow pipeline; 5, hydraulic flow control valve; 6, total oil return pipe; 7, blind hole.
