Hydraulic cylinder is common building block in mechanical equipment, and hydraulic cylinder is that hydraulic energy is changed into mechanical energy, is done directly
Line moves back and forth or the hydraulic actuator of pendulum motion, therefore is used widely in the hydraulic system of various machinery, when
There is larger kinetic energy when hydraulic cylinder to stroke end, do not do deceleration processing such as, hydraulic cylinder piston and cylinder cap will occur mechanical
Collision, can explode；It is extremely dangerous, it cannot guarantee that the structural strength of hydraulic cylinder, while piston is fixed difficult, assembles numerous
It is trivial.
Summary of the invention
The invention will solve the problems, such as to be intended to overcome the above-mentioned defect deposited in the prior art, propose that a kind of plate is cut
Cutting mill special-purpose hydraulic cylinder.
The technical solution of the invention is achieved in that
A kind of sheet cutting machine special-purpose hydraulic cylinder, including the piston rod connected on cylinder barrel, cylinder cap, cylinder bottom, piston and piston；
It is equipped with Crossover relief groove on the piston base end face, and is equipped with blind hole in the middle part of Crossover relief groove；The cylinder barrel and
Explosion-proof frame is provided on the outside of cylinder cap；The inner wall of cylinder is equipped with the temperature connecting with external display device and oil liquid gas content
Detector.
Further, the groove depth of the Crossover relief groove is 2-5mm.
Further, the blind hole depth is 5-10mm, a diameter of 10-15mm.
Further, the U-shaped sealing ring of two pass is equipped between the piston rod and cylinder cap.
Further, seal assembly is equipped between the piston and cylinder barrel, which includes the U-shaped sealing in middle position
And its symmetrically arranged guidance tape in two sides.
Further, the inner wall of cylinder is coated with wearing layer.
Further, the cross key indent is through slot structure.
Using above-mentioned technical proposal, the invention is had the beneficial effect that
Piston is sucted provided with Crossover relief groove and for the blind hole of decompression, is started pressure and is greatly reduced, compared with
Under small starting pressure, the movement of oil cylinder piston can be realized, be highly convenient for controlling, reduce impact when plate cutting, prolong
The service life of equipment is grown.It, can be in extraneous convenient understanding oil by the temperature and oil liquid gas content detector of setting
Whether impurity gas content is exceeded in cylinder inner fluid temperature and oil liquid, and oil liquid pressure is precisely controllable.
Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention without any creative labor, may be used also for those of ordinary skill in the art
To obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram of the invention.
Wherein:
1- cylinder barrel；2- cylinder cap；3- cylinder bottom；4- Crossover relief groove；5- blind hole；6- temperature and the detection of oil liquid gas content
Device；7- piston；8- piston rod.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
A kind of sheet cutting machine special-purpose hydraulic cylinder, as shown in Figure 1, including cylinder barrel 1, cylinder cap 2, cylinder bottom 3, piston 7 and piston
The piston rod 8 of upper connection；It is equipped with Crossover relief groove on the piston base end face, and is equipped in the middle part of Crossover relief groove
Blind hole；Explosion-proof frame is provided on the outside of the cylinder barrel and cylinder cap；The inner wall of cylinder is equipped with the temperature connecting with external display device
Degree and oil liquid gas content detector 6.
It, can be in extraneous convenient understanding oil cylinder inner fluid temperature by the temperature and oil liquid gas content detector of setting
And whether impurity gas content is exceeded in oil liquid, oil liquid pressure is precisely controllable.
The groove depth of above-mentioned Crossover relief groove is 2-5mm.In general, blind hole depth is 5-10mm, a diameter of 10-
15mm.Piston endotherm area is small, more convenient operation, due to being provided with Crossover relief groove and for the blind hole of decompression, starting
Pressure is greatly reduced, and under lesser starting pressure, the movement of oil cylinder piston can be realized, be highly convenient for controlling, and is reduced
Impact when plate cutting, extends the service life of equipment.
The U-shaped sealing ring of two pass, good airproof performance are equipped between above-mentioned piston rod and cylinder cap, pressure control is stablized.
Seal assembly is equipped between above-mentioned piston and cylinder barrel, which includes the U-shaped sealing and its two in middle position
The symmetrically arranged guidance tape in side.
Above-mentioned inner wall of cylinder is coated with wearing layer, durable, will not fall off.
Above-mentioned cross key indent is through slot structure, and oil liquid can facilitate arrival piston base, increases oil liquid and piston
Contact area reduces starting pressure.
Deceleration set can be set in cylinder rod, specifically, the set that slows down is conical structure, close to the side outer diameter of piston
Greatly；It can effectively mitigate, prevent the generation of harm, therefore deceleration system is set in hydraulic circuit.Hydraulic cylinder is mechanical equipment
