Metallurgy, press fitting etc..The problems such as existing hydraulic press has that structure is complicated, occupied space is big, inconvenient for operation, job insecurity.
Utility model content
The purpose of this utility model is to provide a kind of vertical integrated hydraulic machine, the vertical integrated hydraulic machine structure is tight
It gathers, is easy to operate, is easy to maintain, the operation is stable.
In order to achieve the above objectives, the technical solution of the utility model are as follows:
A kind of vertical integrated hydraulic machine, including workbench；Four columns are vertically installed on the workbench, it is described
Four columns surround as cube structure；It is provided with crossbeam on the column, hydraulic cylinder is installed on the crossbeam, it is described hydraulic
Cylinder linkage connection has hydraulic stem；The hydraulic stem bottom end is connected with hydraulic platform, and the hydraulic platform can pass through cunning on column
Block does move repeatedly along the vertical direction；The hydraulic cylinder is connect with hydraulic station；The hydraulic station is from top to bottom successively by three four
Electric change valve, check valve, oil feed pump, fuel tank composition；The oil feed pump is connect with fuel tank, and the check valve and oil feed pump connect
It connects, the oil inlet of the three-position four-way electromagnetic directional valve is connect with check valve, two works of the three-position four-way electromagnetic directional valve
Make mouth to connect with the hydraulic fluid port of two chambers above and below hydraulic cylinder respectively, the oil outlet of the three-position four-way electromagnetic directional valve is connect with fuel tank.
Further, exhaust valve is provided on the hydraulic cylinder.When hydraulic cylinder is after mounting or air in system enters,
Portion of air can be retained inside hydraulic cylinder, and is usually not easy to be taken out of by oil liquid in time, due to air in hydraulic cylinder works
Compressibility, can make to vibrate in piston stroke.Exhaust valve is set in hydraulic cylinder, excludes residual air in hydraulic cylinder, makes
The stable work of hydraulic cylinder.
Further, the exhaust valve of the hydraulic cylinder is Integral exhaustion type valve.
Further, the hydraulic cylinder and pipeline use flanged joint.Method downlink connection has the advantages that reliable and stable, can prevent
Only junction becomes weak spot, leads to oil leak.
Further, the oil feed pump is variable pump.Hydraulic press work into when load it is big, movement velocity is slow, when F.F., rewind
Load relative to work into when it is much smaller, but speed but than work into when it is fast, oil feed pump is set as variable pump can be effective
Improve the working efficiency of hydraulic press.
Further, the oil feed pump is variable displacement with constant power pump.Load pressure can be gradually increased when hydraulic press operating condition, be existed
Some potential safety problems, oil feed pump are set as variable displacement with constant power pump, and when load pressure increases, the discharge capacity of pump can and then subtract automatically
It is small, so that hydraulic press is in the working condition of safety.
The utility model has the following beneficial effects: vertical integrated hydraulic machine described in the utility model has compact-sized, operation
Simply, easy to maintain, steady operation and other merits.Oil feed pump is pumped using variable displacement with constant power, can effectively improve the work effect of hydraulic press
Rate and safety；Filter is arranged in oil feed pump front end, can prevent solid impurity particle from entering hydraulic cylinder, hydraulic cylinder is caused to wear；
Check valve is arranged in oil feed pump and three-position four-way electromagnetic directional valve, can prevent oil liquid from flowing back into oil feed pump；Hydraulic cylinder connection uses method
Orchid connection, securely and reliably, can prevent junction from becoming weak spot leads to oil leak；Exhaust valve is arranged in hydraulic cylinder, can exclude hydraulic cylinder
Interior air makes the work that hydraulic cylinder is stable.
