In figure: 1, proportional reversing valve;2, check valve;3, plug-in overflow valve;4, jacking apparatus;5, external control leaks check valve a;6, Solenoid directional control valve;7, external control leaks check valve b.
Specific embodiment
By the following examples can the detailed explanation present invention, the open purpose of the present invention is intended to protect model of the present invention Enclose all interior technological improvements.
The hydraulic control circuit of stretching-machine jacking apparatus in conjunction with described in attached drawing 1, including jacking apparatus 4, plug type overflow Leak check valve a5, solenoid directional control valve 6, external control of valve 3, external control leaks check valve b7, check valve 2 and proportional reversing valve 1, outside external control The oil outlet B7 and oil sources P01 of check valve b7 are let out by piping connection, external control leaks the oil outlet A7 of check valve b7 and ratio is changed To the P1 hydraulic fluid port of valve 1 by piping connection, the leak oil inlet A5 of check valve a5 of A1 hydraulic fluid port and the external control of proportional reversing valve 1 passes through Piping connection, external control leak check valve a5 oil outlet B5 and jacking apparatus 4 plunger shaft by piping connection, plug type overflow By piping connection, the T3 hydraulic fluid port and circuit O of plug-in overflow valve 3 pass through pipe for the P3 hydraulic fluid port of valve 3 and the plunger shaft of jacking apparatus 4 Road connection, the B1 hydraulic fluid port of proportional reversing valve 1 and the rod end chamber of jacking apparatus 4 pass through piping connection;The oil outlet B2 of check valve 2 Rod end chamber with jacking apparatus 4 is by piping connection, and the oil inlet A2 and circuit O of check valve 2 by piping connection, change by ratio Pass through T1 hydraulic fluid port from piping connection to valve 1 and circuit O, the P6 hydraulic fluid port and oil sources P01 of solenoid directional control valve 6 pass through piping connection, electricity By piping connection, the B6 hydraulic fluid port of solenoid directional control valve 6 leaks with external control check valve respectively by the T6 hydraulic fluid port of magnetic reversal valve 6 and circuit L The X7 hydraulic fluid port of control mouth X5, b7 of a5 passes through piping connection;External control leak check valve a5 leakage hole Y5, b7 Y7 hydraulic fluid port difference Pass through piping connection with the hydraulic fluid port of circuit L.
The hydraulic control circuit of the stretching-machine jacking apparatus, the proportional reversing valve 1 are 3-position 4-way Y type.
The hydraulic control circuit of the stretching-machine jacking apparatus, the solenoid directional control valve 6 are two-position four-way.
It is other to be connected as conventional connection.
The hydraulic control circuit for implementing stretching-machine jacking apparatus of the present invention, when band needs jacking upwards, than P1A1, B1T1 oil circuit of example reversal valve 1 are connected, and solenoid directional control valve 6 charges A6T6, P6B6 oil circuit and connects, and external control leaks check valve A5, b7 are opened, and are successively passed through leak check valve b 7, proportional reversing valve 1, external control of external control from the high pressure oil of oil sources P01 and are leaked unidirectionally The plunger shaft of valve a5, the P3 hydraulic fluid port of plug-in overflow valve 3 and jacking apparatus 4, jacking apparatus 4 slowly withstand upwards band it is whole to Upper movement, when strip flatness reaches requirement, jacking process is completed in pressure maintaining;When jacking apparatus 4 needs to retract downwards, ratio P1B1, A1T1 oil circuit of reversal valve 1 is connected, and solenoid directional control valve 6 charges A6T6, P6B6 oil circuit and connects, external control leak check valve a5, External control leaks check valve b7 opening, successively passes through external control from the high pressure oil of oil sources P01 and leaks check valve b7, proportional reversing valve 1, single To the B2 hydraulic fluid port of valve 2, the rod end chamber of jacking apparatus 4,4 off-load of jacking apparatus slowly moves down, finally stops;Due to band Material has a reaction force straight down to piston rod, and rod end chamber moment will form vacuum, passes through proportional reversing valve 1 B1T1 hydraulic fluid port oil liquid has little time to add to rod end chamber, at this time can only be by the oil inlet A2 of check valve 2 come repairing, jacking apparatus 4 piston rod is slowly retracted into home position, during the piston of jacking apparatus 4 extends and retracts, plug-in overflow valve 3 It is used as safety valve;Since jacking apparatus 4 has a top lift to band, band has straight down anti-to piston rod Active force, when the moment that the piston rod of jacking apparatus 4 retracts, rod end chamber will cause emptying phenomenon, and the effect of check valve 2 is exactly Oil liquid is replenished in time.
Part not in the detailed description of the invention is the prior art.
The embodiment selected herein to disclose goal of the invention of the invention, is presently considered to be suitable, still, It is to be understood that the present invention is intended to include all changes and improvement that all belong to the embodiment in this design and invention scope.
