Abstract
The utility model relates to a lubricating oil circuit of a hydraulic machine. The lubricating oil circuit comprises a lubricating oil pump; a suction hole pipeline of the lubricating oil pump is provided with a filter, and a lower port of the suction hole pipeline is inserted into an oil groove; an outlet pipeline of the lubricating oil pump is provided with a pressure adjustment overflow valve used for enabling oil to return to the oil groove; an outlet of the outlet pipeline of the lubricating oil pump is connected with a lubricating oil header pipe by an electromagnetic valve; an outlet of the lubricating oil header pipe is respectively connected with a sliding block lubricating oil pipe and a hydraulic cushion lubricating oil pipe; the hydraulic cushion lubricating oil pipe is provided with a stop valve; British system male threads of two connectors of the stop valve are respectively screwed with a stop valve connector; inner holes at the other ends of the stop valve connectors are respectively provided with a metric system female thread; an oil pipe connector is sheathed on the hydraulic cushion lubricating oil pipe, and the end of the oil pipe connector is respectively connected with the metric system female threads of the stop valve connectors; the inner wall of the oil pipe connector is sealed with the outer wall of the hydraulic cushion lubricating oil pipe by a double-cone blocking sleeve. Under the condition that a hydraulic cushion is not used, the stop valve arranged on the hydraulic cushion lubricating oil pipe can be closed, so that the waste of oil can be avoided.
Description
Technical field
The utility model relates to a kind of hydraulic press, particularly a kind of lubricating oil path of hydraulic press.
Background technique
In prior art, the lubricating oil path of hydraulic press comprises lubricating pump, filter and suction inlet lower end of duct mouth are installed on the suction inlet pipeline of lubricating pump to be inserted in oil groove, on the outlet conduit of lubricating pump, be provided with to the pressure adjustment relief valve of oil groove oil return, the outlet of lubricating pump outlet conduit is connected with lubricating oil main by solenoid valve, and lubricating oil main's outlet is connected with slide block lubricant pipe and hydraulic die cushion lubricant pipe respectively.
Sometimes user does not need to use hydraulic die cushion, and hydraulic die cushion lubricating loop does not have stop valve or other switch gear, after lubricant pump is started, constantly buys oil to slide block and hydraulic die cushion guiding position lubricated, causes fluid waste.
Model utility content
The purpose of this utility model is, overcomes problems of the prior art, and a kind of lubricating oil path of hydraulic press is provided, and can reduce the consumption of lubricant oil.
For solving above technical problem, the lubricating oil path of a kind of hydraulic press of the present utility model, comprise lubricating pump, filter and suction inlet lower end of duct mouth are installed on the suction inlet pipeline of described lubricating pump to be inserted in oil groove, on the outlet conduit of described lubricating pump, be provided with to the pressure adjustment relief valve of described oil groove oil return, the outlet of described lubricating pump outlet conduit is connected with lubricating oil main by solenoid valve, described lubricating oil main's outlet is connected with slide block lubricant pipe and hydraulic die cushion lubricant pipe respectively, on described hydraulic die cushion lubricant pipe, stop valve is installed.
With respect to prior art, the utility model has been obtained following beneficial effect: in the situation that not needing to use hydraulic die cushion, user can close the stop valve on hydraulic die cushion lubricant pipe, and this branch road is cut off, avoid fluid waste, also reduced the power consumption of lubricating pump.
As preferred version of the present utility model, on the male thread made in Great Britain of described stop valve two interfaces, be connected with respectively stop valve joint, the other end endoporus of described stop valve joint is respectively equipped with metric system box thread, described oil connection is sleeved on described hydraulic die cushion lubricant pipe and termination spins mutually with the metric system box thread of described stop valve joint respectively, between the inwall of described oil connection and the outer wall of described hydraulic die cushion lubricant pipe, realizes sealing by bipyramid cutting ferrule.Oil connection is that standard piece adopts metric thread, and stop valve is also standard piece employing inch screw thread, and the internal thread at stop valve joint two ends is supporting with stop valve joint and oil connection respectively, realizes transition and connects.
Accompanying drawing explanation
