Abstract
The utility model relates to a rolling machine hydraulic oil cylinder capable of prolonging the service life. The hydraulic oil cylinder comprises a piston rod, a cylinder barrel and a cylinder cover, wherein the piston rod is provided with a piston part; the outer circle of the piston part is movably matched with the inner wall of the cylinder barrel in a sealing manner; the piston rod is arranged in the cylinder cover in a penetrating manner; a rod end sealing device is arranged between the piston rod and the cylinder cover; an oil-scraping sealing device is arranged on a contact area of the cylinder cover and the piston rod and is positioned on the outer side of the rod end sealing device; and an oil draining channel for draining hydraulic oil scraped from the oil-scraping sealing device is arranged on the cylinder cover and is positioned between the oil-scraping sealing device and the rod end sealing device. The hydraulic oil cylinder provided by the utility model has the advantages that the structure is simple, the oil-scraping sealing device and the oil draining channel are added to the outer side of the cylinder cover while the addition of other parts and processes are avoided, so that the leakage risk of the oil cylinder is lowered and the operation reliability is improved.
Description
Technical field
The utility model relates to technical field of hydraulic oil cylinder, especially a kind of roll squeezer hydraulic jack that can improve working life.
Background technique
Piston rod surface band oil phenomenon can appear in the use under the high frequency operation condition of traditional hydraulic jack, and under the situation of continuous operation, hydraulic oil can't in time volatilize; Can pollute working environment; Need cleaned at regular intervals, increase the maintenance cost, also increased operating cost simultaneously.
The model utility content
The technical problem that the utility model will solve is: overcome the deficiency in the existing technology, a kind of roll squeezer hydraulic jack that can improve working life is provided, adopt rod end draining structure can the hydraulic oil of piston rod surface accumulation be collected and return fuel tank.So just can not pollute working environment, reduce operating cost.
The utility model solves the technological scheme that its technical problem adopted: a kind of roll squeezer hydraulic jack that can improve working life; Comprise piston rod, cylinder barrel and cylinder cap; Described piston rod has piston portion; Described piston portion outer ring cooperates with the inner wall of cylinder motive sealing, and described piston rod is arranged in the cylinder cap, is provided with the stem tip seal device between piston rod and the cylinder cap; The surface of contact of described cylinder cap and piston rod is provided with the wiper seal device; Described wiper seal device is positioned at the outside of stem tip seal device, also is provided with the draining passage of discharging the hydraulic oil that the wiper seal device strikes off on the cylinder cap, and described draining passage is between wiper seal device and stem tip seal device.
For improving the frizing effect, the contact segment of described wiper seal device and piston rod has the film lobe that is obliquely installed to the cylinder cap inboard.
For the hydraulic oil that scrapes is better discharged, described draining passage comprises oil storage tank that circumferentially is opened in the cylinder cap inner ring and the drain tap that is communicated with oil storage tank, and described drain tap is communicated with hydraulic reservoir through pipeline.Oil storage tank is used for temporary transient stores hydraulic pressure oil, does not produce high pressure as far as possible, helps improving the frizing effect.
The beneficial effect of the utility model is; The roll squeezer hydraulic jack that can improve working life of the utility model is simple in structure: at one wiper seal device of cylinder cap outside increase and drain tap; No longer increase other part and operation, reduced the oil cylinder risk of leakage, improved operational safety; Reduce environmental pollution: this draining structure can stop the hydraulic jack hydraulic oil that rod end is taken out of when high frequency is used for a long time effectively, reduces the pollution to working environment, the life cycle that has also prolonged oil cylinder; Be widely used: this draining structure is not single to prevent that for the long-time hydraulic jack that uses of high frequency action rod end from leaking effectively, uses in the hydraulic jack that can under the working environment higher to environmental requirement, use simultaneously.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of most preferred embodiment of the roll squeezer hydraulic jack that can improve working life of the utility model;
Fig. 2 is the partial enlarged drawing at A place among Fig. 1.
Among the figure: 1. piston rod, 2. cylinder barrel, 3. cylinder cap, 4. stem tip seal device, 5. wiper seal device, 6. draining passage.
Embodiment
Combine accompanying drawing that the utility model is done further detailed explanation now.These accompanying drawings are the schematic representation of simplification, the basic structure of the utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As shown in Figure 1, the most preferred embodiment of the roll squeezer hydraulic jack that can improve working life of the utility model comprises piston rod 1, cylinder barrel 2 and cylinder cap 3; Piston rod 1 has piston portion; The piston portion outer ring cooperates with cylinder barrel 2 inwall motive sealings, and piston rod 1 is arranged in the cylinder cap 3, is provided with stem tip seal device 4 between piston rod 1 and the cylinder cap 3; Cylinder cap 3 is provided with wiper seal device 5 with the surface of contact of piston rod 1; Wiper seal device 5 is positioned at the outside of stem tip seal device 4, also is provided with the draining passage 6 of discharging the hydraulic oil that wiper seal device 5 strikes off on the cylinder cap 3, and draining passage 6 is between wiper seal device 5 and stem tip seal device 4.
Draining passage 6 comprises oil storage tank that circumferentially is opened in cylinder cap 3 inner rings and the drain tap that is communicated with oil storage tank, and drain tap is communicated with hydraulic reservoir through pipeline.
When piston rod 1 high frequency motion, the oil film that piston rod 1 surface is taken out of is stopped by wiper seal device 5, flows back to fuel tank through draining passage 6.Solve high frequency action piston rod surface and often be with oily phenomenon.
