Model utility content
The technical problems to be solved in the utility model is: in order to overcome above-mentioned middle Problems existing, provide a kind of stainless steel piston rod.
Described a kind of stainless steel piston rod, comprise the body of rod 1, the described body of rod 1 is coated with wearing layer 2, wearing layer 2 is coated with anticorrosive coat 3, the body of rod 1 inwall is provided with stiffening rib 4 along the circumferential direction, adopt the structure that the buffer part 6 being provided with phenolic resin electroplated coating 5 and spring steel plate formation outside anticorrosive coat 3 is formed, there is good anti-corrosion capacity, reduce resiliently deformable and the plastic deformation of product, improve wear-resisting property, rough surface plates, easy to process, extend the working life of product, reduce costs.
The utility model solves the technological scheme that its technical problem adopts: a kind of stainless steel piston rod, comprises the body of rod 1, the described body of rod 1 is coated with wearing layer 2, wearing layer 2 is coated with anticorrosive coat 3, and the body of rod 1 inwall is provided with stiffening rib 4 along the circumferential direction.
The quantity of described stiffening rib 4 is 6-12 root.
One deck phenolic resin electroplated coating 5 is had outside described anticorrosive coat 3
Described buffer part 6 is made up of 7 layers of spring steel plate.
Described electroplated coating 5 thickness is 8 μm.
The beneficial effects of the utility model are: 1, due to this stainless steel piston rod, comprise the body of rod 1, the described body of rod 1 is coated with wearing layer 2, wearing layer 2 is coated with anticorrosive coat 3, the body of rod 1 inwall is provided with stiffening rib 4 along the circumferential direction, adopt the structure that the buffer part 6 being provided with phenolic resin electroplated coating 5 and spring steel plate formation outside anticorrosive coat 3 is formed, there is good anti-corrosion capacity, reduce resiliently deformable and the plastic deformation of product, improve wear-resisting property, rough surface plates, easy to process, extend the working life of product, reduce costs;
2, owing to having one deck phenolic resin electroplated coating 5 outside described anticorrosive coat 3, adopt electroplated coating, the wear resistance contributing to piston rod strengthens, and adopts phenolic resin as material simultaneously, make piston rod more be added with compactness and anti-pressure and abrasion-proof performance boost, improve abrasion resistant effect and anti-seismic performance;
3, because described buffer part 6 is made up of 7 layers of spring steel plate.When colliding, spring steel plate can protect parts to be damaged distortion effectively, and when piston rod weares and teares, the wearing and tearing length that spring steel plate can be covered the loss, improves the working life of parts;
4, because described electroplated coating 5 thickness is 8 μm, effectively raise the wear-resisting property of product, rough surface plates, with low cost.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the utility model structural representation;
Fig. 2 is sectional view of the present utility model.
In figure: 1, the body of rod; 2, wearing layer; 3, anticorrosive coat; 4, stiffening rib; 5, electroplated coating; 6, buffer part.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
Embodiment's 1 one kinds of stainless steel piston rods, comprise the body of rod 1, the described body of rod 1 is coated with wearing layer 2, wearing layer 2 is coated with anticorrosive coat 3, and the body of rod 1 inwall is provided with stiffening rib 4 along the circumferential direction.
As shown in Figure 1, 2, to embodiment 2 embodiment 2 it improve on the basis of embodiment 1, and the quantity of its stiffening rib 4 is 6-12 root, and stiffening rib 4 is fixed by welding on the inwall of the body of rod 1.More fixedly secure.
As shown in Figure 1, 2, to embodiment 3 embodiment 2 it improve on the basis of embodiment 1, has one deck phenolic resin electroplated coating 5 outside its anticorrosive coat 3, adopts electroplated coating can cover the manufacturing deficiency of piston rod itself, extend the working life of piston rod.
As shown in Figure 1, 2, to embodiment 4 embodiment 2 it improve on the basis of embodiment 1, and its buffer part 6 is made up of 7 layers of spring steel plate.Stress supplementary result, because surface layer leaves surface compress residual stresses, contributes to closing of surperficial fine crack, hinders the expansion of corrosion function.Thus improve surperficial anti-corrosion capacity, and the generation of energy delay fatigue crackle or expansion, thus improve cylinder rod fatigue strength.
As shown in Figure 1, 2, to embodiment 5 embodiment 2 it improve on the basis of embodiment 1, and its electroplated coating 5 thickness is 8 μm.Electroplated coating is too thin can not cover in the manufacturing deficiency of piston rod itself, too thick and can rub, so pass through roll forming, rolling surface forms one deck flow harden layer, decrease elasticity and the plastic deformation of the secondary contact surface of grinding, thus improve the wear resistance on cylinder rod surface, avoid the burn because grinding causes simultaneously.After roll extrusion, the reduction of surface roughness value, can improve fiting property.Meanwhile, to the frictionally damage of seal ring or Sealing when reducing cylinder rod piston movement, improve the whole service life of oil cylinder.
Embodiment's 6 one kinds of stainless steel piston rods, have the body of rod 1, the body of rod 1 are coated with wearing layer 2, wearing layer 2 is coated with anticorrosive coat 3, and the body of rod 1 inwall is provided with stiffening rib 4 along the circumferential direction.Buffer part 6 is had outside the body of rod 1.The quantity of stiffening rib 4 is 6-12 root, has one deck phenolic resin electroplated coating 5 outside described anticorrosive coat 3, and described buffer part 6 is made up of 7 layers of spring steel plate.Described electroplated coating 5 thickness is 8 μm.Described a kind of piston rod, structure is simple, easy to use, has good anti-corrosion capacity, and reduce resiliently deformable and the plastic deformation of product, improve wear-resisting property, rough surface plates, easy to process, extends the working life of product, reduces costs.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this model utility technological thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to right.
