Description
Technical field
The present invention relates to knife striking cylinder technical field, in particular to a kind of pneumatic 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 pneumatic cylinder is entirely beaten
The reaction rate of knife cylinder and the precision of operation.
The content of the invention
For above-mentioned technical problem, the pneumatic cylinder of knife striking cylinder of the present invention is used for above knife striking cylinder hydraulic cylinder to hydraulic pressure
Cylinder realizes pressurization, have the advantages that be swift in response, stroke it is accurate.
To achieve the above object, the present invention designed by a kind of knife striking cylinder pneumatic cylinder, be divided into top the first air cavity and
Two regions of the second air cavity of lower part, being spaced apart by cylinder piston sealing between first air cavity and second air cavity；
The cylinder piston is being provided with cylinder piston rod positioned at the one side of second air cavity, and the cylinder piston rod runs through institute
The lower part of the second air cavity is stated, and is tightly connected with perforative position；
The first air-flow interface is offered on first air cavity, the second air-flow interface is offered on second air cavity.
As the preferred of above-mentioned technical proposal, detour is provided between the first air-flow interface and first air cavity
Passage.
As the preferred of above-mentioned technical proposal, detour is provided between the second air-flow interface and second air cavity
Passage.
As the preferred of above-mentioned technical proposal, the O-ring card slot of annular is provided on the outside of the cylinder piston.
As the preferred of above-mentioned technical proposal, the lower surface of the cylinder piston is circular plane.
As the preferred of above-mentioned technical proposal, the cylinder piston rod is arranged at the center of circle of the cylinder piston lower surface
On.
As the preferred of above-mentioned technical proposal, end of the cylinder piston rod away from the cylinder piston is outwardly
Arcwall face.
During pushing, pushing process when outwardly arcwall face is contacted with oil phase is softer, and oil phase is more collected
In push center to, positioning is more accurate.
As the preferred of above-mentioned technical proposal, the upper surface of the cylinder piston is downward concave arcwall face, transversal
Face is circle, and minimum point and the circular center of circle in cross section of the arcwall face coincide.
When downward concave arcwall face so that gas pushes, cylinder piston pressure focuses more on circle centre position, alleviates
Unbalanced stress suffered by cylinder piston adds its durability, and pushing positioning is more accurate, and has saved portion of material
Cost.
During practical operation, gas first passes through the first air-flow interface into the first air-chamber pressing, by the related cylinder of cylinder piston
Piston rod is pressed downward, and the gas of the second air cavity is automatically flowed out from the second air-flow interface at this time, is realized under cylinder piston rod
Press operation；During reset, gas first passes through the second air-flow interface into the second air-chamber pressing, by the related cylinder piston rod of cylinder piston
It pushes up, the gas of the first air cavity is automatically flowed out from the first air-flow interface at this time, realizes the reset operation of cylinder piston rod.
Compared with prior art, the present invention haing the following advantages and advantageous effect：
The pneumatic cylinder of the knife striking cylinder pressurizes for being realized to hydraulic cylinder above knife striking cylinder hydraulic cylinder, have be swift in response, stroke
The advantages of accurate.
