According to the double-oil-seal hydraulic oil cylinder of the vulcanizing machine, the oil seal ring is additionally arranged on the lower portion of the guiding face of the hydraulic oil cylinder, increase of the cost is not obvious, a relatively-closed liquid oil space is formed between the oil seal ring and the existing oil seal ring of the opening of the hydraulic oil cylinder, the sealing effect of the hydraulic oil cylinder is greatly improved, the replacement time of the oil seal rings is prolonged to be longer than the doubled existing replacement time, overall performance of the hydraulic oil cylinder is more stable, and the trouble, of frequent replacement of the oil seal rings, of rubber enterprises is eliminated.
Description
Technical field
The utility model relates to a kind of hydraulic jack, specifically relates to a kind of vulcanizer dual-oil seal hydraulic jack.
Background technique
In the use of rubber vulcanizing machine, the stability of the hydraulic system of vulcanizer has very large significance for a whole set of machine.And the linking relationship of hydraulic jack and plunger is particularly important in hydraulic system.Plunger and hydraulic jack all belong to the large parts of vulcanizer, and installation precision is had relatively high expectations, and change oil seal washer trouble effort, but also need professional workforce to install, and change debugging.Plunger and oil cylinder are born the function that pressure transmits, and the pressure galling that oil seal washer is born is fast aging serious, and work under bad environment, is the main easily damaged parts of vulcanizer oil cylinder.In traditional hydraulic jack technological design, be only provided with one oil seal washer of cylinder ports, although facilitate some while replacing, seepage and replacement cycle, short problem existed always, was perplexing rubber production enterprise.
Model utility content
In order to solve the problems of the technologies described above, the utility model provides a kind of vulcanizer dual-oil seal hydraulic jack.
The technical solution that the utility model adopts is:
A kind of vulcanizer dual-oil seal hydraulic jack, comprise cylinder block and piston, described piston is placed in cylinder block, and can to-and-fro motion in cylinder body, extend cylinder body from cylinder body opening one end of described piston, on cylinder body opening end face, offers the first oil seal groove, the first oil seal washer is installed in the first oil seal groove, on inboard wall of cylinder block, offer the second oil seal groove, the second oil seal washer is installed in the second oil seal groove, the first oil seal washer and the second oil seal washer are all enclosed within on piston.
Preferably, above the first oil seal washer, be provided with flange, flange is screwed on cylinder body opening end face, and by the first oil seal washer compacting, a dust ring is installed above flange.
Preferably, the spacing between described the first oil seal washer and the second oil seal washer is 10～20cm.
Preferably, the bottom of described cylinder body is set to hold the chamber of piston, and the top of described cylinder body is set to be communicated with lower chamber and internal diameter is less than the guide chamber of lower chamber, and described the second oil seal groove is opened in the guide surface bottom of cylinder body guide chamber periphery.
Useful technique effect of the present utility model is:
This device has been set up an oil seal washer in the bottom of hydraulic jack guide surface, cost increases and is not obvious, but between the original oil seal washer of this oil seal washer and cylinder ports, form a relative airtight fluid space, its sealing effect is strengthened a lot, phenomenon and the probability of leakage of oil reduce greatly, and the replacing time of oil seal washer has also extended more than one times, the overall performance of oil cylinder is more stable, for rubber enterprise has reduced the trouble of frequent replacing oil seal washer, save expense, bring certain economic benefit, also for vulcanizer manufacturer has reduced a large sum of after sales service expense, realize the effect of doulbe-sides' victory.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail:
Fig. 1 is structural principle schematic diagram of the present utility model;
Fig. 2 is the structural representation of cylinder block in the utility model.
In figure: 1-cylinder block, 2-piston, 3-chamber, 4-guide chamber, 5-the first oil seal groove, 6-the first oil seal washer, 7-flange, 8-dust ring, 9-the second oil seal groove, 10-the second oil seal washer, 11-fluid space.
Embodiment
By reference to the accompanying drawings, a kind of vulcanizer dual-oil seal hydraulic jack, comprises cylinder block 1 and piston 2.The bottom of cylinder block 1 is set to chamber 3, and the top of cylinder block 1 is set to be communicated with lower chamber 3 and internal diameter is less than the guide chamber 4 of lower chamber 3.Piston 2 is placed in the chamber 3 of cylinder block, and can to-and-fro motion in chamber, and extend outside cylinder body through guide chamber 4 and cylinder body opening one end of piston 2.On cylinder body opening end face, offer the first oil seal groove 5, in interior installation the first oil seal washer 6 of the first oil seal groove 5.Above the first oil seal washer 6, be provided with flange 7, flange 7 is screwed on cylinder body opening end face, and by the first oil seal washer 6 compactings.A dust ring 8 is installed above flange 7, between the first oil seal washer 6 and piston 2, is scratched the first oil seal washer 6 and piston 2 to prevent that impurity from entering.On inboard wall of cylinder block and the guide surface bottom that is positioned at guide chamber 4 peripheries offer the second oil seal groove 9, in interior installation the second oil seal washer 10 of the second oil seal groove 9.The first oil seal washer 6, dust ring 8 and the second oil seal washer 10 are all enclosed within on piston 2.Spacing between the first oil seal washer 6 and the second oil seal washer 10 is 10～20cm.
This device has been set up i.e. the second oil seal washer 10 of an oil seal washer in the bottom of hydraulic jack guide surface, cost increases and is not obvious, but between original the first oil seal washer 6 of this second oil seal washer 10 and cylinder ports, form a relative airtight fluid space 11, its sealing effect is strengthened a lot, phenomenon and the probability of leakage of oil reduce greatly, and the replacing time of oil seal washer also extended more than one times, the overall performance of oil cylinder is more stable.In the time that system is pressurizeed, the inner side of oil seal washer is fitted in more closely on piston outer wall and oil seal groove inwall under pressure.In addition, second oil seal washer 10 of setting up also has another advantage, and also combine closely in the top of the upside of the second oil seal washer 10 and the second oil seal groove 9 in the situation that of pressurization, also has except increasing pressure-acting the effect that strengthens sealing.And the flange contact facings of the first oil seal washer 6 tops that cylinder ports place arranges only provides the effect of pressure.
The relevant technologies content of not addressing in aforesaid way is taked or is used for reference prior art and can realize.
It should be noted that, under the instruction of this specification, any equivalents that those skilled in the art have done, or obvious variant, all should be within protection domain of the present utility model.
