Abstract
The utility model discloses a water cooling piston rod of a hydraulic cylinder. The hydraulic cooling piston rod of the cylinder water comprises a piston rod body, a water inlet, a water outlet and a cooling water pipe with the large diameter. The piston rod body is hollow, the cooling water pipe with the large diameter is arranged in a cavity of the piston rod body, the water inlet and the water outlet are formed in the same side of the piston rod body, the water outlet is communicated with the cooling water pipe with the large diameter, and the water inlet is communicated with the cavity of the piston rod body. The hydraulic cylinder with the improved water cooling piston rod is unchanged in installing size, only a water inlet pipe and a water outlet pipe need to be additionally arranged, the temperature of the piston rod is reduced, heat conduction is blocked, and the service life of a shaft seal of the hydraulic cylinder is prolonged.
Description
Technical field
The utility model belongs to the metallurgical equipment auxiliary device, and concrete is a kind of oil hydraulic cylinder water-cooled piston bar.
Background technique
Tension leveller of continuous casting machine is in hot environment for a long time, for avoiding the radiation of oil hydraulic cylinder long term high temperature, usually with the oil hydraulic cylinder position design in the zone of avoiding the direct radiation of high temperature, or with the hydraulic cylinder body water-cooled, but cylinder water-cooling causes the corresponding increase of diameter of cylinder.But under many circumstances, due to the restriction that is subject to the space, oil hydraulic cylinder both can't be avoided high-temperature area, and diameter of cylinder can't increase again, and piston rod directly is in the hyperthermia radiation zone like this, and surface temperature reaches 170 ℃, and it has had a strong impact on the work of oil hydraulic cylinder.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of oil hydraulic cylinder water-cooled piston bar,
Reduce the piston rod temperature, the conduction of blocking-up heat extends oil hydraulic cylinder working life.
A kind of oil hydraulic cylinder water-cooled piston of the utility model bar, it comprises the piston body of rod, water intake, water outlet and major diameter water-cooling tube, the described piston body of rod is hollow, the major diameter water-cooling tube is arranged in the cavity of the piston body of rod, water intake, water outlet are opened in the same side of the piston body of rod, water outlet is connected with the major diameter water-cooling tube, and water intake is connected with piston body of rod cavity.
Described a kind of oil hydraulic cylinder water-cooled piston bar also comprises minor diameter water-cooling tube and seal ring, and described minor diameter water-cooling tube is arranged on piston body of rod cavity inside, is connected with the major diameter water-cooling tube, connects the gap seal ring is set.
Cooling water enters piston rod cavity by water intake, flows into the minor diameter cooling tube, then through major diameter cooling tube drain opening, the piston rod heat is taken away.
Oil hydraulic cylinder after the cold piston rod of the utility model modify-water, installation dimension do not change, and only need to increase turnover water pipe and get final product, reduce the piston rod temperature, the conduction of blocking-up heat, prolongation oil hydraulic cylinder shaft seal working life.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1, the piston body of rod 2, major diameter water-cooling tube 3, minor diameter water-cooling tube 4, water intake 5, water outlet 6, seal ring.
Embodiment
Referring to accompanying drawing, a kind of oil hydraulic cylinder water-cooled piston bar, it comprises the piston body of rod 1, water intake 4, water outlet 5 and major diameter water-cooling tube 2, the described piston body of rod is hollow, the major diameter water-cooling tube is arranged in the cavity of the piston body of rod, water intake, water outlet are opened in the same side of the piston body of rod, and water outlet is connected with the major diameter water-cooling tube, and water intake is connected with piston body of rod cavity.
Described a kind of oil hydraulic cylinder water-cooled piston bar also comprises minor diameter water-cooling tube 3 and seal ring 6, and described minor diameter water-cooling tube is arranged on piston body of rod cavity inside, is connected with the major diameter water-cooling tube, connects the gap seal ring is set.
Cooling water enters piston rod cavity by water intake, flows into the minor diameter cooling tube, then through major diameter cooling tube drain opening, the piston rod heat is taken away.
The utility model by at the inner turnover water pipe that increases of piston rod, reduces the piston rod temperature under the prerequisite that does not increase the oil hydraulic cylinder cylinder diameter, the conduction of blocking-up heat extends the oil hydraulic cylinder that is in hot environment working life.
