Abstract
The utility model discloses a hydraulic cylinder piston rod, comprising a piston rod body. The surface of the piston rod body is provided with a nickel-plate layer; and the upper side of the nickel-plate layer is provided with a hard chrome layer. The nickel-plate layer and the hard chrome layer disposed successively on the finished piston rod body work together to improve corrosion resistance of the piston rod and thus can prolong the service lifetime of the piston rod effectively when the piston rod is used in ships, ports, coal mines and other open work environments with corrosiveness. The utility model relates to the field of manufacture of piston rods.
Description
Technical field
The utility model relates to a kind of mechanical rod member, particularly relates to a kind of hydraulic cylinder piston rod.
Background technique
Plating is to utilize electrolysis on machinework, to deposit to adhere to technology good but performance and body material different metallic coating.Electrodeposited coating is more even than hot dipping layer, and is generally all thinner, do not wait to tens microns from several microns.Through electroplating, can on machinework, obtain to decorate protectiveness and various functional surface layer, can also repair the workpiece of wearing and tearing and processing error.
Because boats and ships, harbour, colliery or other contain the open-air working environment particularity of aggressive atmosphere; The mechanical universal demand that is used for boats and ships, harbour and colliery has higher decay resistance; So piston rod in the past adopts stainless steel to make mostly; And the piston rod surface durionise that is processing; To strengthen its decay resistance, tended to cause the cost of making piston rod too high but make piston rod through this kind material and this kind technology, its decay resistance can not effectively be guaranteed simultaneously.
The model utility content
For addressing the above problem, the utility model provides a kind of piston rod that can effectively strengthen its decay resistance.
The utility model solves the technological scheme that its technical problem adopted:
A kind of hydraulic cylinder piston rod comprises the piston rod body, and the surface of piston rod body is provided with nickeling layer, and the upside of nickeling layer also is provided with one deck hard chromium layers.
Further as the improvement of the utility model technological scheme, the piston rod body adopts No. 45 steel or 40G steel.
Further as the improvement of the utility model technological scheme, nickeling layer is electrodeposited coating or chemical deposit, contains 9% to 12% phosphorus in the nickeling layer.
Further as the improvement of the utility model technological scheme, hard chromium layers is an electrodeposited coating.
The beneficial effect of the utility model: this hydraulic cylinder piston rod has set gradually nickeling layer and hard chromium layers at the piston rod body surface that machines; As the nickeling layer of bottom with as the hard chromium layers acting in conjunction on top layer; Can effectively strengthen the decay resistance of piston rod; Thereby be used in boats and ships, harbour, colliery or other when containing in the open-air working environment of aggressive atmosphere, can effectively prolonging the working life of piston rod.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is a piston rod body surface coating structure schematic representation among the utility model embodiment;
Fig. 2 is the overall structure schematic representation of piston rod body among the utility model embodiment.
Embodiment
With reference to Fig. 1, Fig. 2, the utility model is a kind of hydraulic cylinder piston rod, comprises piston rod body 1, and the surface of piston rod body 1 is provided with nickeling layer 2, and the upside of nickeling layer 2 also is provided with one deck hard chromium layers 3.
This hydraulic cylinder piston rod has set gradually nickeling layer 2 and hard chromium layers 3 on piston rod body 1 surface that machines; As the nickeling layer 2 of bottom with as hard chromium layers 3 actings in conjunction on top layer; Can effectively strengthen the decay resistance of piston rod; Thereby be used in boats and ships, harbour, colliery or other when containing in the open-air working environment of aggressive atmosphere, can effectively prolonging the working life of piston rod.
As the improvement of the utility model technological scheme, piston rod body No. 45 steel of 1 employing or 40G steel.
Because the hard chromium layers 3 on nickeling layer of bottom 2 and top layer all has stronger decay resistance, so can adopt the material of No. 45 lower steel of relative price or 40G steel matter, the fabricating cost that helps saving piston rod body 1 man-hour in adding of piston rod body 1.
Simultaneously; After two-layer protective layer was added on piston rod body 1 surface that relatively inexpensive steel are made, stainless steel surfaces added the processing mode of one deck hard chromium layers relatively in the past, can reduce the electroplating thickness of hard chromium layers 3 relatively; Also can reach corresponding decay resistance, save electroplating cost simultaneously.
As the improvement of the utility model technological scheme, nickeling layer 2 is electrodeposited coating or chemical deposit, contains 9% to 12% phosphorus in the nickeling layer 2.
As the improvement of the utility model technological scheme, hard chromium layers 3 is an electrodeposited coating.
Certainly; The invention is not limited to above-mentioned mode of execution; Those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite of the utility model spirit, modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
