Extreme difficulties will be brought to the design of hydraulic system.
By traditional design method, stretching unit generally use the structure of two main stretching cylinders with
Ensure the stress balance of active chuck, before being distributed in the both sides promotion activity jointly of active chuck
Enter, retreat, so also tend to also bring a synchronism deviation problem, this just to hydraulic pressure, electrically
System design brings certain difficulty, and floor space is big.
Summary of the invention
It is an object of the invention to for deficiency of the prior art, it is provided that be adapted to the double of stretching-machine
Plunger type compound hydraulic cylinder device.
For achieving the above object, the invention discloses following technical scheme:
A kind of Double-plunger compound hydraulic cylinder device, including vat, little cylinder, bow beam, connecting rod
With active chuck, vat and little cylinder all use piston structure, vat, little cylinder mutually to utilize and reality
Existing drawback movement；
Vat cylinder body is fixed, and big cylinder plug is arranged in vat cylinder interior, and little cylinder cylinder body is arranged on
Vat cylinder body afterbody, big cylinder plug is local hollow shape, and little cylinder cylinder body is assemblied in this Vacancy
Putting, little cylinder plug is arranged in little cylinder cylinder interior；Little cylinder plug acts in active chuck frame；
Big cylinder plug is connected with bow beam by nut, and bow beam connects by being arranged in the connecting rod of both sides
Active chuck frame.
Further, described connecting rod is connected by bearing pin with active chuck frame.
Further, totally two, described connecting rod, it is respectively arranged on the bow beam left and right sides.
A kind of Double-plunger compound hydraulic cylinder device disclosed by the invention, has following useful effect
Really:
It is provided simultaneously with the big load of low speed, high speed side crops industry and broken belt pooling feature；The most integrated set
Meter, have employed single cylinder drawing process and instead of traditional twin-tub drawing process, efficiently solves double
Cylinder synchronism deviation problem.
Accompanying drawing explanation
Fig. 1 is compound hydraulic cylinder device sectional view；
Fig. 2 is compound hydraulic cylinder device top view.
Wherein: 1, bow beam；2, big cylinder plug；3, vat cylinder body；4, little cylinder cylinder body；5、
Little cylinder plug；6, connecting rod；7, bearing pin；8, active chuck.
Detailed description of the invention
Below in conjunction with embodiment and referring to the drawings the invention will be further described.
Refer to Fig. 1-Fig. 2.
A kind of Double-plunger compound hydraulic cylinder device, including vat, little cylinder, bow beam 1, connects
Bar 6 and active chuck 8, vat and little cylinder all use piston structure, and vat, little cylinder are mutually mutually beneficial
With and realize drawback movement；
Vat cylinder body 4 is fixed, and it is internal that big cylinder plug 2 is arranged in vat cylinder body 1, little cylinder cylinder body
4 are arranged on vat cylinder body 3 afterbody, and big cylinder plug 2 is local hollow shape, little cylinder cylinder body 4
Being assemblied in this hollow position, it is internal that little cylinder plug 5 is arranged in little cylinder cylinder body 4；Little cylinder plug 5
Act in active chuck 8 frame；Big cylinder plug 2 is connected with bow beam 1 by nut, bow
Ellbeam 1 connects active chuck 8 frame by being arranged in the connecting rod 6 of both sides.
Vat drives active chuck 8 to move back and forth by bow beam 1, solves tradition stretching-machine
The synchronism deviation problem of double master cylinder arrangement.Mutually utilized by large and small cylinders such as pull rod device and real
Now stretching, drawback movement, high speed little load when the big load of low speed and backhaul when simultaneously meeting stretching
Lotus special operation condition demand.When material stretching is ruptured suddenly, little cylinder is for bearing fixed chuck
Ballistic movement.
As specific embodiment, described connecting rod 6 is connected by bearing pin with active chuck 8 frame.
As specific embodiment, totally two, described connecting rod 6, it is respectively arranged on bow beam about 1 two
Side.
Patent of the present invention mainly proposes a kind of Double-plunger composite hydraulic cylinder being adapted to stretching-machine
Device, two plunger-type cylinders are integrated by this hydraulic cylinder cleverly, and vat is used for drawing
Stretch operating mode, it is achieved the big loading movement of low speed；And little cylinder is for the backhaul operating mode of active chuck, use
In realizing the motion of high speed side crops industry.In structure designs, in cleverly vat plunger design being become
Hollow structure, and little cylinder cylinder body is arranged in vat plunger body.
Meanwhile, linkage, vat, little cylinder is make use of mutually to utilize realization in structure designs
Drawback movement.When stretching, big cylinder plug 2 promotes bow beam 1 to move in orbit, arch
Beam 1 drives active chuck 8 to move by being arranged in the connecting rod 6 of both sides, now by active chuck 8
Little cylinder plug 5 is reversely pushed back little cylinder, and little cylinder is in draining state；Otherwise, at active chuck 8
During drawback movement, little cylinder oil-feed, its plunger promotes active chuck 8 to retreat, and accordingly, utilizes
Connecting rod 6 drives bow beam 1 rollback, is thus simultaneously achieved the plunger drawback movement of vat.
When active chuck 8 needs drawback movement, high pressure liquid force feed is entered in little cylinder by flange
And promoting little cylinder plug 5 to move, little cylinder plug 5 acts directly in active chuck 8 frame, directly
Connect promotion active chuck 8 drawback movement.Now, active chuck 8 drives vat post by connecting rod 6
Plug 2 and bow beam 1 drawback movement, now vat is in pressure release state.Owing to little cylinder plug 5 is straight
Footpath is much smaller than big cylinder plug 2, and the hydraulic flow meeting master cylinder stretching can meet active chuck 8 simultaneously
The motion requirement of high speed side crops industry.At the medium and small cylinder of drawing process as buffering hydraulic cylinder, can meet
Suddenly the buffer protection demand ruptured during material stretching.
When material stretches, high pressure liquid force feed is entered in vat by flange, promotes big cylinder plug
2 move to draw direction, and big cylinder plug 2 is connected by big nut with bow beam 1, bow beam 1
Driving active chuck 8 to move by being arranged in the connecting rod 6 of both sides, connecting rod 6 passes through with active chuck 8
Bearing pin connects.Now, active chuck 8 drives little cylinder plug 5 drawback movement by connecting rod 6, this
Time little cylinder be in pressure release state.This function is used for stretching operating mode, meets the big load requirements of low speed.
The above is only the preferred embodiment of the present invention, is not intended to limit；It should be pointed out that,
Although the present invention being described in detail with reference to the various embodiments described above, the ordinary skill of this area
Personnel should be appreciated that the technical scheme described in the various embodiments described above still can be repaiied by it
Change, or the most some or all of technical characteristic is carried out equivalent；And these are revised and replace
Change, do not make the essence of corresponding technical scheme depart from the model of various embodiments of the present invention technical scheme
Enclose.
