The scheme that the utility model solve the technical problem is:
A kind of extrusion press oil cylinder bonnet fixing seal device, comprise cylinder body, described cylinder body is made up of cylindrical shell and cylinder bottom, the front end of cylinder bottom has projection circle upwards, protruding circle sleeve is on the madial wall of the bottom of cylindrical shell, the madial wall of the bottom of cylindrical shell forms annular groove, O-ring seal is nested in annular groove, O-ring seal is clamped in annular groove with on the protruding outer wall enclosed, cylinder bottom is bolted to connection on cylindrical shell, is clamped with seal ring between the ear end face of cylindrical shell and the front-end face of cylinder bottom.
The rear end outer side wall of described cylindrical shell forms radial extension edge, the front end outer side wall of cylinder bottom forms radial connection extension edge, cushion is clamped between radial extension edge and radial connection extension edge, and screw bolt passes radial direction connects extension edge, cushion and radial extension edge and the set screw nut that is spirally connected.
The edge portion of the front-end face of described radial direction connection extension edge forms groove, and cushion is in a groove nested.
The front-end face of described cylinder bottom forms annular groove, and the bottom surface of annular groove is inclined-plane.
The ear end face of described cylindrical shell is oblique.
Described seal ring is nested in annular groove, and the upper-end surface of seal ring and lower end surface are oblique, and seal ring is clamped between the ear end face of cylindrical shell and the bottom surface of annular groove.
Outstanding effect of the present utility model is:
Compared with prior art, its cylinder body is split-type structural, and for convenience detach and maintenance, its maintenance cost is low, effective.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Embodiment, see as shown in Figure 1, a kind of extrusion press oil cylinder bonnet fixing seal device, comprise cylinder body 1, described cylinder body 1 is made up of cylindrical shell 11 and cylinder bottom 12, the front end of cylinder bottom 12 has projection circle 121 upwards, protruding circle 121 sleeves are on the madial wall of the bottom of cylindrical shell 11, the madial wall of the bottom of cylindrical shell 11 forms annular groove 111, O-ring seal 2 is nested in annular groove 111, O-ring seal 2 is clamped in annular groove 111 and encloses on the outer wall of 121 with protruding, cylinder bottom 12 is fixedly connected on cylindrical shell 11 by bolt 3, seal ring 4 is clamped with between the ear end face of cylindrical shell 11 and the front-end face of cylinder bottom 12.
The rear end outer side wall of described cylindrical shell 11 forms radial extension edge 112, the front end outer side wall of cylinder bottom 12 forms radial connection extension edge 122, cushion 5 is clamped between radial extension edge 112 and radial connection extension edge 122, and bolt 3 connects extension edge 122, cushion 5 and radial extension edge 112 and the set screw nut 7 that is spirally connected through radial successively.
The edge portion of the front-end face of described radial direction connection extension edge 122 forms groove 123, and cushion 5 is nested in groove 123.
The front-end face of described cylinder bottom 12 forms annular groove 124, and the bottom surface of annular groove 124 is inclined-plane.
The ear end face of described cylindrical shell 11 is oblique.
Described seal ring 4 is nested in annular groove 111, and the upper-end surface of seal ring 4 and lower end surface are oblique, and seal ring 4 is clamped between the ear end face of cylindrical shell 11 and the bottom surface of annular groove 111.
Working principle: in the present embodiment, the rear end outer side wall of described cylindrical shell 11 forms radial extension edge 112, the front end outer side wall of cylinder bottom 12 forms radial connection extension edge 122, cushion 5 is clamped between radial extension edge 112 and radial connection extension edge 122, and bolt 3 connects extension edge 122, cushion 5 and radial extension edge 112 and the set screw nut 7 that is spirally connected through radial successively; So just by swivel bolt 3 and set screw nut 7, the tightness connected between cylindrical shell 11 and cylinder bottom 12 can be regulated, thus make seal ring 4 produce compressive strain, ensure sealing effect.
Simultaneously, the front end of the cylinder bottom 12 that it adopts has projection circle 121 upwards, protruding circle 121 sleeves are on the madial wall of the bottom of cylindrical shell 11, the madial wall of the bottom of cylindrical shell 11 forms annular groove 111, O-ring seal 2 is nested in annular groove 111, O-ring seal 2 is clamped in annular groove 111 and encloses on the outer wall of 121 with protruding, so just makes sealing effect between cylinder bottom 12 and cylindrical shell 11 better.
