Needs；In prior art, hydraulic cylinder is not prevented from rising the parts of cylinder, piston be in irremovable in the case of continue inwards
Face is filled with hydraulic fluid and will rise cylinder phenomenon, and such hydraulic fluid will heat up, and affects the service life of hydraulic cylinder, even damages
Bad.
Summary of the invention
The purpose of the present invention is aiming at disadvantages mentioned above, it is provided that one is possible to prevent hydraulic fluid to heat up, guarantee normally uses,
The cylinder phenomenon that will not rise from pressure release hydraulic cylinder, also provide for a kind of reducing the steel that hydraulic cylinder heats up, ensures service life simultaneously
Muscle bending machine.
The technical scheme of self-unloading hydraulic cylinder of the present invention is achieved in that from pressure release hydraulic cylinder, including cylinder barrel and piston, institute
The cylinder barrel stated has first import and export and second of hydraulic fluid and imports and exports, and described piston is arranged in cylinder barrel, and piston connects to be had
Connecting rod；
It is characterized in that: described internal piston has hollow core structures, described hollow core structures is that two ends are through, at hollow
The left end of structure is left inside protrusion rib, and the right-hand member in hollow core structures is right projecting inward rib, also has two tapers in hollow core structures
Block, is left circular cone and right circular cone respectively, has and have jurisdiction over the groove of spring and use spring between left circular cone and right circular cone
Connect left circular cone and right circular cone；
When described left circular cone is on the left of hollow core structures, left circular cone becomes to seal cooperation with left inside protrusion prismatic；
When described right circular cone is on the right side of hollow core structures, right circular cone prismatic projecting inward with the right side becomes to seal cooperation；
Being fixedly connected with one section of push rod after described right circular cone, push rod right-hand member exceedes on the right side of piston；
Described connecting rod is arranged on left circular cone.
The technical scheme of angle-bender of the present invention is achieved in that angle-bender, including bending machine body, described
Bending machine body there is hydraulic cylinder, described hydraulic cylinder is above-mentioned hydraulic cylinder.
The invention has the beneficial effects as follows:
Such have from pressure release hydraulic cylinder be possible to prevent hydraulic fluid to heat up, ensure normal to use, the cylinder that will not rise existing
The advantage of elephant, further can improve the speed of service；
Such angle-bender has minimizing hydraulic cylinder and heats up, it is ensured that the advantage in service life.
Accompanying drawing explanation
The structural representation of Fig. 1 the first state of present hydraulic cylinder.
The structural representation of Fig. 2 present hydraulic cylinder the second state.
The structural representation of Fig. 3 the third state of present hydraulic cylinder.
Wherein: 1, cylinder barrel 2, piston 3, first import and export the 4, second import and export 5, connecting rod 7, hollow core structures 8, left inside
Protrude rib 9, right projecting inward rib 10, left circular cone 11, right circular cone 12, spring 13, push rod.
Detailed description of the invention
The present invention is described further below in conjunction with the accompanying drawings.
As shown in Figure 1, 2, 3, from pressure release hydraulic cylinder, including cylinder barrel 1 and piston 2, described cylinder barrel has the of hydraulic fluid
One imports and exports 3 and second imports and exports 4, and described piston 2 is arranged in cylinder barrel 1, and piston 2 connects connecting rod 5；
It is characterized in that: described internal piston has hollow core structures 7, described hollow core structures is that two ends are through, at sky
The left end of cored structure is left inside protrusion rib 8, and the right-hand member in hollow core structures has right projecting inward rib 9, also has two in hollow core structures
Individual circular cone, is left circular cone 10 and right circular cone 11 respectively, has jurisdiction over spring between left circular cone 10 and right circular cone 11
The groove of 12 also connects left circular cone and right circular cone with spring；
When described left circular cone is on the left of hollow core structures, left circular cone 10 and left inside protrusion rib 8 are formed to seal and coordinate, as
Shown in Fig. 3.
When described right circular cone is on the right side of hollow core structures, right circular cone 11 and the right side projecting inward rib 9 are formed to seal and coordinate, as
Shown in Fig. 2.
Being fixedly connected with one section of push rod 13 after described right circular cone, push rod right-hand member exceedes on the right side of piston；
Described connecting rod 5 is arranged on left circular cone 10.
When hydraulic fluid imports and exports 3 entrance from first, the most left circular cone 10, under the effect of hydraulic fluid pressure, is transported to the right
OK, opening on the left of such hollow core structures, hydraulic fluid enters in hollow core structures, is still that right circular cone is made at hydraulic fluid pressure to the right
Under with, during due to described right circular cone on the right side of hollow core structures, right circular cone prismatic projecting inward with the right side becomes to seal cooperation, hydraulic pressure
Liquid will not be crossed this and seal structure, imports and exports continuation injection hydraulic fluid piston first and will run to the right, to extreme position
Time, push rod 13 will act on the sidewall on the right side of cylinder barrel, and right circular cone prismatic projecting inward with the right side becomes to seal cooperation will be beaten
Opening, continue to inject hydraulic fluid, hydraulic fluid will be imported and exported from second and release, and has advantages of the present invention, as shown in Figure 2.
Then hydraulic fluid is imported and exported from second and is entered, during due to described left circular cone on the left of hollow core structures, and left taper
Block becomes to seal cooperation with left inside protrusion prismatic, and piston can run to the left, returns initial position, comes and goes, such as Fig. 3 next time
Shown in.
The technical scheme of angle-bender of the present invention is achieved in that angle-bender, including bending machine body, described
Bending machine body there is hydraulic cylinder, described hydraulic cylinder is above-mentioned hydraulic cylinder.
The foregoing is only the specific embodiment of the present invention, but the architectural feature of the present invention is not limited to this, any ability
The technical staff in territory is in the field of the invention, and change or the modification made all are contained in the scope of the claims of the present invention.
