Abstract
The utility model relates to a novel split type oil cylinder device with a sealed conical surface. A cylinder barrel (5) of an oil cylinder is installed in an inner cavity of an outer supporting component (1), the inner bottom of the cylinder barrel (5) is an inner conical structure, and an outer circle of a cylinder bottom (3) is an outer conical surface. The outer conical surface of the cylinder bottom (3) contacts the conical surface which is arranged at the bottom of the cylinder barrel (5) under the action of high pressure oil which is contained in the inner cavity of the cylinder barrel (5) to achieve the sealing function. Simultaneously, the outer supporting component (1) is led to bear pressure through a flange which is arranged on the left end of the cylinder barrel (5).
Description
Affiliated technical field
The utility model relates to a kind of cylinder apparatus that produces hydraulic pressure, especially bears the cylinder apparatus of high strength hydraulic pressure.
Background technique
At present, the cylinder apparatus (as the man-made diamond pressing machine oil cylinder) in the need high strength hydraulic work equipment, two kinds of structures are arranged, a kind of is integrated type, promptly in a unitary steel material of forging, produce a hydraulic pressure inner chamber, the forward path filler opening at one end is set, built-in packed-piston of the other end and return filler opening with machining mode through punching press, promote piston advances forward by filler opening input high pressure oil, move backward by the return hydraulic fluid port, as shown in Figure 1, among Fig. 1: 1, oil cylinder.The oil cylinder of this structure is owing to need the processing inner chamber, processing cost height, and sectional dimension became uneven, and heat treatment easily produces defective; Another kind of oil cylinder is that oil cylinder is divided into cylinder barrel and cylinder bottom two-part, as shown in Figure 2, and among Fig. 2: 1, cylinder letter; 2, cylinder bottom.This structure is that cost is low, and in actual use, because cylinder barrel separates with cylinder bottom, the pressure that oil pressure produces makes outer supporting element bear the high load pulling force by the outer supporting element that cylinder bottom passes to, and makes outer supporting element (Cast Steel) bottom cause fracture damage easily.
Summary of the invention
For overcoming existing oil cylinder processing cost height, sectional dimension is inhomogeneous, easily produces heat treating fault and the outer supporting element of protection, improves outer supporting element working life.The utility model provides a kind of oil cylinder.This oil cylinder is not only easy to process, and heat treatment process is simple, and outer supporting element can be born pulling force and change to and bear pressure, prolongs outer supporting element working life.
The technological scheme that its technical problem that solves the utility model adopts is: oil cylinder is separated into cylinder barrel and cylinder bottom two-part, and the cylinder barrel inner bottom part is designed to the inner conical structure, and the design of cylinder barrel left side has flange (Φ D
1＞Φ D
2), the outer garden of cylinder bottom is designed to outer wimble structure (Φ d
1＞Φ d
2), design and installation seal ring on the cylinder bottom external conical shape face.The cylinder bottom that has seal ring when cylinder bottom is subjected to oil pressure pressure is to the motion of cylinder barrel bottom, contact with the cylinder barrel bottom, rely on inside and outside cone seal, simultaneously, pressure that cylinder bottom bears is passed to outer supporting element by the conical surface contact by the cylinder barrel flange, make outer supporting element bottom bear pressure.
The beneficial effects of the utility model are: utilize the conical surface sealing time cylinder bottom to be born pressure and pass to outer supporting element by cylinder barrel, make outer supporting element bear pressure, prolong outer supporting element working life.
Description of drawings
Below in conjunction with accompanying drawing three and embodiment the utility model is further specified.
Fig. 1 is integrated type cylinder apparatus figure.
Fig. 2 is that oil cylinder is divided into cylinder barrel and the two-part cylinder apparatus figure of cylinder bottom.
Fig. 3 is a mechanical ssembly drawing of the present utility model.
Among Fig. 3: 1, outer supporting element; 2, reverse stops; 3, cylinder bottom; 4, seal ring; 5, cylinder barrel; 6, piston; 7, seal ring.
Embodiment
In Fig. 3, cylinder barrel (5) is installed in outer supporting element (1) inner chamber, cylinder barrel (5) inner chamber is equipped with cylinder bottom (3) and piston (6), on cylinder bottom (3) the external conical shape face seal ring is arranged, cylinder bottom (3) center is provided with oilhole, when high pressure oil enters cylinder barrel (5) inner chamber by cylinder bottom (3) oil inlet hole, after promotion piston (6) travels forward and arrives stroke terminal, high pressure oil promotes cylinder bottom (3) simultaneously and moves round about, under the effect of high pressure oil, cylinder bottom (3) contacts with the inner conical surface of cylinder barrel (2) with seal ring by the external conical shape face and reaches sealing effect, simultaneously cylinder bottom (3) pressure is passed to outer supporting element (1) by cylinder barrel (5) flange, make outer supporting element (1) reach the purpose of bearing pressure.Cylinder bottom (3) outer end connects reverse stops (2) by bolt, prevents when playing oil-feed that cylinder bottom (3) from moving in oil pocket.
Claims (2)
1, a kind of novel split type conical surface seal cylinder apparatus, outside in the supporting element inner chamber, the cylinder barrel of oil cylinder is installed, inner cavity of cylinder is equipped with piston and cylinder bottom, reverse stops is equipped with in the cylinder bottom bottom, and it is characterized in that: cylinder barrel separates with cylinder bottom, and the outer garden of cylinder bottom is external conical shape, the cylinder barrel inner bottom part is inner conical, and cylinder bottom contacts with the cylinder barrel that is the inner conical bottom by external conical shape face and seal ring.
2, a kind of novel split type conical surface seal cylinder apparatus according to claim 1 is characterized in that: the outer garden of cylinder barrel left end be an end greater than the other end, be flange-like, be supported on outer supporting element one end.
