Description
Technical field
The invention belongs to technical field of hydraulic, be specifically related to a kind of hydraulic synchronization oil channel structures being mainly used in the synchronous liftout attachment of hydraulic press.
Background technique
As shown in Figure 1, the synchronous oil channel structures of existing known hydraulic press hydraulic synchronization liftout attachment forms primarily of synchronous fuel tank group 1 and benefit oil-releasing mechanism 2, its working principle is: synchronous fuel tank group 1 is general by ejection cylinder 11, and synchronous fuel tank 12 and synchronous oil duct 13 form.The oil pocket 111 of ejection cylinder 11 is connected with the oil pocket 121 of synchronous fuel tank 12 by synchronous oil duct 13, thus forms synchronous oil pocket.During normal work, synchronous oil pocket is closed, drive the motion of the piston rod 122 of synchronous fuel tank 12 to make the fluid in oil pocket 121 inject the oil pocket 111 of ejection cylinder 11 by synchronous oil duct 13, thus promote piston rod 112 accompany movement of ejection cylinder 11, namely realize the synchronization control of oil cylinder.Usually, piston rod 112 is provided with exhaust port 113, and uses plug screw shutoff.And mend the benefit displacement configuration that oil-releasing mechanism 2 mends oil extraction oil duct 21 and functional switch 22 form single oil duct primarily of: mending oil extraction oil duct 21 is communicated with synchronous oil pocket, and functional switch 22 is arranged on benefit oil extraction oil duct 21.During normal work, functional switch 22 is in closed condition, ensures that synchronous oil pocket is closed; When synchronous oil pocket fluid is not enough or leak, then open function switch 22, by mending oil extraction oil duct 21 to synchronous oil pocket repairing.
Usually, the table top that ejection cylinder 11 is arranged on brick machine is connected with mould, and synchronous fuel tank 12 is then arranged in control valve group.As required, generally multi-cylinder synchronous liftout attachment is formed by the synchronous fuel tank group 1 of more than 2 or 2 with benefit oil-releasing mechanism 2; Meanwhile, link together with the piston rod 122 of contiguous block by all synchronous fuel tanks 12, driven by same oil cylinder.But the volume of ejection cylinder 11 and synchronous fuel tank 12 is general less, and synchronous oil duct 13 is longer, and the benefit oil-releasing mechanism of single oil duct can not realize the fluid replacing function of synchronous oil pocket, causes fluid easily aging and quality decline, affects net synchronization capability.And have gas in synchronous oil pocket, gas can not be discharged by the benefit oil-releasing mechanism of single oil duct, causes synchronization accuracy to reduce.Therefore, need to arrange other gas collection and discharging mechanism, namely exhaust port 113 is set on piston rod 112, and use plug screw shutoff, during exhaust, then unscrew plug screw.But piston rod 112 is connected with mould and is stopped, bleeding must first breaks in production mould of dismantling, and causes the inconvenience on use and maintenance.
Summary of the invention
