The utility model discloses a set up the cooling water course in the front end housing, utilize the cooling water to carry out effectual cooling at the circulation flow of cooling water course to parts such as bearing, sealing washer in the front end housing, prevented to cause the damage of bearing, sealing washer because the high temperature, ensured hydro-cylinder job stabilization nature, be favorable to extension hydro-cylinder life.
Description
Technical Field
The utility model belongs to the technical field of the hydraulic cylinder technique and specifically relates to a protecgulum water-cooled extrusion hydro-cylinder.
Background
The extrusion oil cylinder adopted in the die-casting industry is mostly arranged at the position close to the die core inside the die, the working environment of the extrusion oil cylinder is severe due to the high temperature inside the die, and the bearing, the sealing ring and other components at the front end of the oil cylinder are easily heated and damaged, so that the service life of the oil cylinder is shortened. The normal work of hydro-cylinder is guaranteed to current extrusion hydro-cylinder adoption high temperature resistant sealing washer mode more, but still can't thoroughly solve the hydro-cylinder and be heated and the problem that breaks down.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: in order to overcome the defects in the prior art, the utility model provides a can effectively reduce the inside temperature of hydro-cylinder front end, ensure the normal running water-cooled extrusion hydro-cylinder of protecgulum of hydro-cylinder.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a front cover water-cooled extrusion hydro-cylinder, has the cylinder, and the cylinder front end links firmly has the front end housing, is equipped with in the cylinder with cylinder inner wall sliding fit's piston, the piston connection have stretch out the outer piston rod of front end housing, the interval is equipped with the first hydraulic fluid port that communicates there is the pole chamber and communicates the second hydraulic fluid port in no pole chamber on the cylinder, the front end housing in be equipped with the cooling water course, the water-cooling mouth of business turn over cooling water is seted up respectively to corresponding cooling water course both ends on the front end housing.
Preferably, the cooling water channel is square and is arranged around the bearing seat of the inner support piston rod of the front end cover.
The utility model has the advantages that: the utility model discloses a set up the cooling water course in the front end housing, utilize the cooling water to carry out effectual cooling at the circulation flow of cooling water course to parts such as bearing, sealing washer in the front end housing, prevented to cause the damage of bearing, sealing washer because the high temperature, ensured hydro-cylinder job stabilization nature, be favorable to extension hydro-cylinder life.

Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
The front cover water-cooled extrusion oil cylinder shown in fig. 1 and 2 comprises a cylinder barrel 1, wherein a front end cover 2 is fixedly connected to the front end of the cylinder barrel 1, a piston 3 in sliding fit with the inner wall of the cylinder barrel 1 is arranged in the cylinder barrel 1, the piston 3 is connected with a piston rod 4 extending out of the front end cover 2, and a first oil port 5 communicated with a rod cavity of the oil cylinder and a second oil port 6 communicated with a rodless cavity of the oil cylinder are arranged on the cylinder barrel 1 at intervals.
The front end cover 2 is internally provided with a cooling water channel 7, and the front end cover 2 is provided with water cooling ports 8 for feeding and discharging cooling water corresponding to the two ends of the cooling water channel 7.
Specifically speaking, the cooling water channel 7 is formed by connecting four water distribution channels, and each water distribution channel is 45 degrees with a vertical line or a horizontal line of the central line of the front end cover 2, so that the four water distribution channels are connected into the cooling water channel 7 which is square and distributed around the bearing seat of the support piston rod 4 in the front end cover 2, cooling water added from the water cooling port 8 continuously circulates and flows in the cooling water channel 7 to take away a large amount of heat, thereby effectively cooling a bearing, a sealing ring and the like in the front end cover 2, preventing the damage of the bearing and the sealing ring caused by overhigh temperature, ensuring the working stability of the oil cylinder, and being beneficial to prolonging the service life of the oil cylinder.
In particular, the cooling water channel 7 may be formed in other geometric shapes, and may be selectively matched according to the shape of the front end cover 2.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
