Abstract
The utility model relates to an anticorrosion wear-resisting hydraulic cylinder, characterized in that the outside surface of a piston rod is wrapped by a layer of stainless steel plate, wherein the surface of the stainless steel plate is plated with hard chrome, and thereby the surface of the hydraulic cylinder piston rod has the same anticorrosion capability as the stainless steel, also has the same wear resistance as the chrome plated piston rod.
Description
Technical field
The utility model relates to a kind of oil hydraulic cylinder: a kind of piston rod matrix parcel one deck corrosion resistant plate, the chromed hardened again oil hydraulic cylinder in corrosion resistant plate surface.
Background technique
At present, the chrome faced method of the many employings of the piston rod outer surface of oil hydraulic cylinder realizes the anticorrosion and wear-resisting of piston rod.Because the piston rod chromium coating is thin and pin hole is arranged, and makes oil hydraulic cylinder in use, piston rod is easy to be corroded and causes the inefficacy of oil hydraulic cylinder.Particularly work as hydraulic cylinder works in the environment of moist or the liquid that is corrosive, caused the oil hydraulic cylinder failure conditions very easily to take place owing to piston rod corrodes.
Summary of the invention
In order to solve that the piston rod chromium coating is easy to be corroded and the Problem of Failure that causes oil hydraulic cylinder, the utility model provides a kind of oil hydraulic cylinder, the piston rod of this oil hydraulic cylinder has the anti-corrosion capacity identical with stainless steel, has the wear resistance identical with the chrome-plated piston bar simultaneously.
Technical solution adopted in the utility model is: at outer surface parcel one deck corrosion resistant plate of piston rod matrix, described corrosion resistant plate is welded into tubulose, be wrapped in the outer surface of piston rod closely, the two ends of pipe and the welding of piston rod matrix, the outer surface that stainless steel is formed carries out grinding then, again to the stainless steel surfaces hard chromium plating after the grinding.
The oil hydraulic cylinder that the present invention relates to can be a first-stage cylinder, also can be secondary cylinder or multistage cylinder.
Description of drawings
Fig. 1 is the one-level oil hydraulic cylinder;
Fig. 2 is the amplification profile of the local A of one-level hydraulic cylinder piston rod;
Fig. 3 is a two-stage hydraulic cylinder.
Above-mentioned number in the figure is described as follows:
1-one-level hydraulic cylinder body, 2-one-level hydraulic cylinder piston rod, 3-corrosion resistant plate, 4-hard chromium plating layer, 5-one-level hydraulic cylinder piston rod matrix, the one-level cylinder body of 6-two-stage hydraulic cylinder, the secondary cylinder body of 7-two-stage hydraulic cylinder, the piston rod of 8-two-stage hydraulic cylinder.
Embodiment
Corrosion resistant plate 3 is wrapped in the outer surface of one-level hydraulic cylinder piston rod matrix 5 closely.With the butt joint welding of corrosion resistant plate 3, the corrosion resistant plate 3 after the welding becomes tubulose.With the two ends and the welding of one-level hydraulic cylinder piston rod matrix of tubulose corrosion resistant plate 3, tubulose corrosion resistant plate 3 and one-level hydraulic cylinder piston rod matrix 5 are become one again, become one-level hydraulic cylinder piston rod 2.Hard chromium plating layer 4 is again carried out after the grinding on the corrosion resistant plate surface of one-level hydraulic cylinder piston rod 2.
The mode of execution of two-stage hydraulic cylinder cylinder body 7 and 2-level hydraulic cylinder piston rod 8 is identical with one-level hydraulic cylinder piston rod 2.
Because one-level hydraulic cylinder piston rod 2, the secondary cylinder body 7 of two-stage hydraulic cylinder, piston rod 8 outer surfaces of two-stage hydraulic cylinder have all been implemented parcel corrosion resistant plate 3 hard chromium plating layer 4 again, make piston rod (the comprising the secondary cylinder body) surface of the oil hydraulic cylinder of its formation have the anti-corrosion capacity identical, also have simultaneously and the identical wear resistance of chrome-plated piston bar (comprising the secondary cylinder body) with stainless steel.
Technical solutions according to the invention also can be used for multistage cylinder.
