Abstract
The utility model relates to a hydraulic machine fuel tank equipped with a device collecting leakage oil, comprising a cylinder body, a plunger, a guide sleeve and sealing ring positioned at the bottom of the inner wall of the cylinder, a flange fixed at the bottom of the cylinder and a dustproof ring positioned on the round hole wall of the flange, and it is characterized in that: a ring storage tank is arranged on ring storage tank at the junction of the flange and the plunger, an oil recovery hole leading to the outer wall of the flange is provided in the middle of the ring storage tank, the exit of the oil recovery hole positioned at the outer wall of the flange is connected with a guide pipe, and the sealing ring is positioned between the dustproof ring and the ring storage tank and is positioned on the round hole wall of the junction of the plunger and the flange. The utility model has the advantages of that: it can lead hydraulic oil leaked due to the partial loading of the fuel tank back to the fuel tank through the guide oil pipe, for re-using and reducing waste and preventing hydraulic oil from leaking out of the junction of the flange and the plunger to pollute hydraulic machines.
Description
Technical field
The utility model belongs to the component of press machine, particularly relates to a kind of oil cylinder that leakage loss oil gathering-device is housed.
Background technique
In known technology, the operating cylinder of hydraulic press is normally by cylinder body, be contained in the plunger in the cylinder body, be contained in the guide pin bushing and the seal ring of inboard wall of cylinder block lower end, be enclosed within on the plunger and be fixed on the flange plate of cylinder body lower end, and the formations such as dust ring that are contained in the lower end of flange plate, hydraulic press is when carrying out operation, usually because last, the deviation of counterdie location, the plunger that makes the lower end be connected with slide block or pressure head produces skew radially, cause the unbalance loading of oil cylinder, thereby make hydraulic oil sew from the junction point of flange plate and plunger, so not only cause the waste of hydraulic oil, but also can pollute hydraulic press.
Summary of the invention
The utility model provides a kind of hydraulic press oil cylinder that leakage loss oil gathering-device is housed that can recycle the hydraulic oil that leaks out for solving the technical problem that exists in the known technology.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of hydraulic press oil cylinder that leakage loss oil gathering-device is housed, comprise cylinder body, be contained in the plunger in the cylinder body, be contained in the guide pin bushing and the seal ring of inboard wall of cylinder block lower end, be enclosed within on the plunger and be fixed on the flange plate of cylinder body lower end, and be contained in dust ring on flange plate and the circular hole wall plug engages place, on flange plate, be equiped with leakage loss oil gathering-device, its structure is: on flange plate and the circular hole wall plug engages place, be positioned at dust ring above have annular oil storage tank around its inwall, neutral position in the annular oil storage tank has the recovery oilhole that leads to the flange plate outer wall, the outlet port that is positioned at the flange plate outer wall of reclaiming oilhole is connected with honeycomb duct, between dust ring and annular oil storage tank seal ring is housed on circular hole wall flange plate and the plug engages place.
The utility model can also adopt following technical measures:
Junction point at described cylinder body and flange plate is equipped with whole rounded sectionally assembled adjustment pad.
Advantage and the good effect that the utlity model has are: the hydraulic oil that can leak out oil cylinder generation unbalance loading draws by honeycomb duct to be got back in the fuel tank, again utilize, cut the waste, and can avoid hydraulic oil to sew and hydraulic press is polluted from the junction point of flange plate and plunger.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the partial enlarged drawing of Fig. 1;
Fig. 3 is the structural representation of adjustment pad of the present utility model.
Number in the figure is respectively: the 1-plunger; The 2-dust ring; The 3-seal ring; 4-annular oil storage tank; 5-reclaims oilhole; 6-adjusts pad; The 7-guide pin bushing; The 8-combined seal ring; The 9-guide pin bushing; The 10-cylinder body; The 11-flange plate; The 12-honeycomb duct; The 13-seal ring.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 and Fig. 2, the oil cylinder of leakage loss oil gathering-device is housed, be provided with cylinder body 10, plunger 1 is housed in the cylinder body, have circular concave station at the inboard wall of cylinder block lower end, guide pin bushing 9 is housed on the concave station successively, combined seal ring 8 and guide pin bushing 7, on plunger, be with flange plate 11, it is screwed in the cylinder body lower end, on flange plate and the circular hole wall plug engages place, dust ring 2 is housed, on flange plate, be equiped with leakage loss oil gathering-device, its structure is: 4 places above the dust ring on the flange plate also have an annular oil storage tank around its inwall, neutral position in the annular oil storage tank has a recovery oilhole 5 that the hydraulic oil that spills is drawn that is used for that leads to the flange plate outer wall, pipe joint is equipped with in the outlet port that is positioned at the flange plate outer wall of reclaiming oilhole, is connected with honeycomb duct 12 on the pipe joint, and honeycomb duct is connected to fuel tank, in order to prevent that hydraulic oil from spilling from annular oil storage tank, on circular hole wall flange plate and the plug engages place, between dust ring and annular oil storage tank, seal ring 3 is housed.Because behind the hydraulic press work certain hour, combination seal has certain wearing and tearing, usually need change combination seal, in order to prolong its working life, at the junction point of cylinder body and flange plate as shown in Figure 3 whole rounded sectionally assembled adjustment pad is housed, so that after the combination seal wearing and tearing, use the method for its removal is regulated, in addition, seal ring 13 also is housed on the outer wall of guide pin bushing 7, spills from the junction point of cylinder body and flange plate to prevent hydraulic oil.
Leakage of oil when taking place owing to unbalance loading in oil cylinder of the present utility model, hydraulic oil can accumulate in the annular oil storage tank, and when the oil that accumulates reached the height that reclaims oilhole, both diversed pipe was drawn, flow in the fuel tank, the oil that accumulates simultaneously also can play certain lubrication to plunger.
