Abstract
The invention discloses a controllable hydraulic system of a rolling machine which comprises an oil pump that is connected with an oil tank. The oil pump is connected with an electromagnetic directional valve which is connected with an inserted unidirectional valve. The inserted unidirectional valve is connected with a working cylinder. An accumulator group is arranged on an oil duct between the inserted unidirectional valve and the working cylinder. A depressurized circuit of the accumulator group is provided with a releasing time controllable valve group. The controllable hydraulic system of the rolling machine is provided with a reasonable structure. The stroke of a main valve core can be controlled by an adjustable handle on the controllable valve group. Thus, the time for releasing pressure from the controllable valve group can be controlled when the main valve core. If the releasing time is required to be changed, only the adjustable handle is required to be adjusted. The controllable hydraulic system of the rolling machine has the advantages of simple operation, no need for the disassembly, convenient maintenance and greatly improved production efficiency.
Description
Technical field:
The present invention relates to a kind of rolling machine hydraulic system.
Background technology:
Rolling machine hydraulic system is for the roll squeezer left and right sides provides suitable loading force, and overall system is divided into two shunt, controls the boosting of the left and right sides, pressurize, release respectively.Can realize any combination of any two groups of actions by the power on/off of electromagnet.When boosting, pump installation is oil suction from fuel tank, through the oil cylinder LOADED CAVITY in solenoid directional control valve (getting), plug-in mounting check valve, the right side that enters roll squeezer, left side, is the accumulator pressurising simultaneously.Pressurize is a solenoid directional control valve dead electricity after pressurization is finished, and comes pressurize by the accumulator of both sides.Stress-relief process is meant at the working cylinder of both sides need adjust the position, needs release pressure, promptly discharges the storage power of accumulator.As release energy too much, just need boost again, repetitive operation is lost time, and influences technological process, reduces production efficiency.
Summary of the invention:
The object of the present invention is to provide a kind of rational in infrastructure, the controllable type rolling machine hydraulic system that the release pressure time is adjustable.
Technical solution of the present invention is:
A kind of controllable type rolling machine hydraulic system, comprise the oil pump that is connected with fuel tank, oil pump is connected with solenoid directional control valve, solenoid directional control valve is connected with the plug-in mounting check valve, the plug-in mounting check valve is connected with operating cylinder, on the oil duct, be provided with the accumulator group between plug-in mounting check valve and the operating cylinder, it is characterized in that: on the depressurized circuit of accumulator group, be provided with controlled valve group release time.
Release time, the controlled valve group comprised controlled valve, and the spool of controlled valve is connected with the spool position regulating block, and the spool position regulating block is connected with regulating handle, and an electromagnetic priority valve is in parallel with controlled valve.
The present invention is rational in infrastructure, controls the stroke of the main valve heart by the adjustable handle on the controlled valve group, make its when work on the controlled valve group the time of release pressure can control.Change release time as needs, only need to regulate adjustable handle, it is simple to operate, need not dismounting, and is easy to maintenance, enhances productivity greatly.
Description of drawings:
The invention will be further described below in conjunction with drawings and Examples.
Accompanying drawing is the configuration diagram of one embodiment of the invention.
The specific embodiment:
A kind of controllable type rolling machine hydraulic system, comprise the oil pump 2 that is connected with fuel tank 1, oil pump is connected with solenoid directional control valve 3, solenoid directional control valve is connected with plug-in mounting check valve 4, the plug-in mounting check valve is connected with operating cylinder 5, on the oil duct, be provided with accumulator group 6 between plug-in mounting check valve and the operating cylinder, on the depressurized circuit of accumulator group, be provided with controlled valve group release time.
Release time, the controlled valve group comprised controlled valve 8, the spool 9 of controlled valve is connected with spool position regulating block 10, the spool position regulating block is connected with regulating handle 11, comes the position (stroke) of regulating spool by regulating handle and by the spool position regulating block, and an electromagnetic priority valve 7 is in parallel with controlled valve.
