Abstract
The utility model relates to a long stroke, major diameter pottery piston rod hydraulic cylinder device, including the cylinder body, the axle center of cylinder body has a piston hole, the piston hole is the blind hole, places ceramic piston rod in the piston hole, and end cover, bottom end cover are installed respectively to the axial both ends of cylinder body, and the upper end cover is installed in the open end position of piston hole, and wherein the upper end cover is passed to the one end of ceramic piston rod, passes the ceramic piston rod free end installation lug of upper end cover to the length of ceramic piston rod is good at to the length of piston hole, the utility model discloses a piston rod long service life does not pollute the environment.
Description
Technical field
This utility model relates to a kind of Long travel, major diameter ceramic cylinder rod cylinder system.
Background technology
China's hydraulic cylinder piston rod anticorrosion mode is for a long time based on electrodeposited chromium layers, and the plating processing of heavy metal chromium relates to the use of strong acid, highly basic, and environmental pollution is serious.
Utility model content
The purpose of this utility model is in that to overcome the above-mentioned problems in the prior art, it is provided that a kind of Long travel, major diameter ceramic cylinder rod cylinder system.The technical scheme realizing above-mentioned purpose is as follows:
Long travel, major diameter ceramic cylinder rod cylinder system, including cylinder body, the axle center of cylinder body has piston hole, described piston hole is blind hole, placing ceramic piston rod in piston hole, the axial two ends of cylinder body are respectively mounted upper end cover, bottom end cover, upper end cover is arranged on the opening position of piston hole, wherein one end traverse upper end cover of ceramic cylinder rod, ceramic cylinder rod free end through upper end cover installs hanger, and the length of piston hole is longer than the length of ceramic cylinder rod, the stroke of piston rod is made to form affluence.
Described ceramic cylinder rod includes steel mandrel, the surface spraying coating of mandrel, and described coating is metal oxide ceramic layer, and the thickness of coating is 300～500 μm, hardness is 800HV～1300HV.
This utility model piston rod stroke is long, long service life.
Accompanying drawing explanation
Fig. 1 is this utility model schematic diagram
Figure number illustrates: cylinder body 1, piston hole 2, ceramic cylinder rod 3, upper end cover 4, bottom end cover 5, hanger 6, control device 7
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in detail.
In figure, Long travel, major diameter ceramic cylinder rod cylinder system includes cylinder body 1, the axle center of cylinder body 1 has piston hole 2, described piston hole 2 is blind hole, placing ceramic piston rod 3 in piston hole 2, the axial two ends of cylinder body 1 are respectively mounted upper end cover 4, bottom end cover 5, upper end cover 4 is arranged on the opening position of piston hole 2, wherein one end traverse upper end cover 4 of ceramic cylinder rod 3, ceramic cylinder rod 3 free end through upper end cover 4 installs hanger 6, and the length of piston hole 2 is longer than the length of ceramic cylinder rod 3, so, when ceramic cylinder rod 3 moves back and forth, its stroke has affluence, ceramic cylinder rod 3 is avoided to sustain damage, when installing ceramic cylinder rod 3, lifted by crane by hanger 6.
Described ceramic cylinder rod 3 includes steel mandrel, the surface spraying coating of mandrel, and described coating is metal oxide ceramic layer, and the thickness of coating is 300～500 μm, hardness is 800HV～1300HV, bond strength 15～40MPa；After grinding, surface roughness is less than Ra0.63, and dimensional accuracy can reach f6；Service life controls device more than 1200km, also includes controlling device 7 in this utility model, controls to electrically connect between device 7 and ceramic cylinder rod, controls the stroke of ceramic cylinder rod 3 by controlling device 7, controls device and use prior art.
The thrust 11000KN of ceramic cylinder rod in this utility model, pulling force 8600KN, stroke 11520mm, the bar footpath 540mm of ceramic cylinder rod.
Environmental pollution that ceramic cylinder rod electroless plating layers of chrome causes, service life several times higher than chrome-plated piston bar, and ceramic cylinder rod has natural anticorrosion erosion performance, acid, alkali, salt corrosion are respectively provided with good barrier propterty, and Ceramic piston rod oil cylinder application prospect is widely.
These are only the preferred embodiment of this utility model embodiment; not in order to limit this utility model embodiment; within all spirit in this utility model embodiment and principle, any amendment of making, equivalent replacement, improvement etc., should be included in the protection domain of this utility model embodiment.
