Description
Technical field
The present invention relates to knife striking cylinder technical field, in particular to a kind of hydraulic cylinder of knife striking cylinder.
Background technology
Knife striking cylinder is that a kind of power for being punched out to forging, in the relatively process such as straight, bending, extrusion forming passes
Pass mechanism, generally use pneumatic cylinder and oil hydraulic cylinder linkage realize power conduction, and the wherein structures shape of hydraulic cylinder is entirely beaten
The punching press dynamics and stability of knife cylinder.
The content of the invention
For above-mentioned technical problem, the hydraulic cylinder of knife striking cylinder of the present invention is for knife striking cylinder, in pushing away for pneumatic cylinder
The advantages of dynamic lower realize is pressurizeed, and has punching press great efforts, and stability is good.
To achieve the above object, the hydraulic cylinder of a kind of knife striking cylinder designed by the present invention, hydraulic cavities and lower part by top
Atmospheric pressure cavity form, be provided with hydraulic piston between the hydraulic cavities and the atmospheric pressure cavity, the lower part of the hydraulic piston is set
There is liquid presses piston pole；
Liquid phase interface is provided at the top of the hydraulic cavities, the bottom of the atmospheric pressure cavity is provided with gas phase interface；
The liquid presses piston pole is tightly connected through the lower part of the atmospheric pressure cavity and with through part.
As the preferred of above-mentioned technical proposal, the upper and lower surface of the hydraulic piston is the flat of circular contour
Face.
As the preferred of above-mentioned technical proposal, the circle centre position of the hydraulic piston upper surface offers hydraulic pressure groove.
As the preferred of above-mentioned technical proposal, the hydraulic pressure groove is columned groove, runs through the hydraulic piston
And part is deep into the liquid presses piston pole.
As the preferred of above-mentioned technical proposal, the bottom surface of the hydraulic pressure groove is reclinate arcwall face.
Hydraulic pressure groove concentrates oil phase in the inner, enables to what hydraulic coupling more concentrated to act on liquid presses piston pole,
It realizes larger stamping press and the punching press effect stablized, and part oil phase dosage can be saved.
As the preferred of above-mentioned technical proposal, the groove for mounting O-shaped rings is offered on the hydraulic piston side wall.
As the preferred of above-mentioned technical proposal, the bottom of the liquid presses piston pole is provided with punch.
In actual use, under the drive of pneumatic cylinder, hydraulic piston is depressed into downwards centainly by oil phase together with liquid presses piston pole
Stroke, at this time the air in atmospheric pressure cavity discharged automatically by gas phase interface, a punching press is realized, during reset, from gas phase interface to gas
Intracavitary pressurization to be pressed, hydraulic piston is pushed up into reset together with liquid presses piston pole, oil phase is flowed out by liquid phase interface out of hydraulic cavities,
Until it completes to reset.
Compared with prior art, the present invention haing the following advantages and advantageous effect：
The hydraulic cylinder of the knife striking cylinder is used for knife striking cylinder, and pressurization is realized under the promotion of pneumatic cylinder, has punching press great efforts, stablizes
The advantages of property is good.
