Abstract
The utility model relates to a kind of Cylinder Plunger head being provided with wear-resistant sleeve, and comprise plunger rod and plug, described plug is fixedly connected with one end of plunger rod, has mounting hole in the middle part of described plug, is close to mounting hole inwall and is provided with wear-resistant sleeve.The utility model has installed wear-resistant sleeve in mounting hole, can prevent mounting hole from wearing and tearing or scratch, the working life of plug is increased, and the working life of cylinder plunger can also be improved further by the method changing high-strength wearable cover simultaneously, not only change simple use, and compared with original plug, its working life increases greatly, Safety performance promotes huge.
Description
Technical field
The utility model relates to Cylinder Plunger head technical field, particularly relates to a kind of Cylinder Plunger head being provided with wear-resistant sleeve.
Background technique
Oil hydraulic cylinder is mechanically operated important actuator, especially large-scale oil hydraulic cylinder to be widely used ladle at metallurgy industry, after the wearing and tearing of Con casting ladle traverse platform lifting master cylinder plug mounting hole, if continue use to there is potential safety hazard, all do not repair both at home and abroad at present, but directly scrap and cause waste.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of Cylinder Plunger head being provided with wear-resistant sleeve, reduce the wearing and tearing of large_sized hydraulic cylinder plug, working life is extended, and can also be improved the working life of cylinder plunger by the method changing high-strength wearable cover further simultaneously.
The utility model solves the technological scheme that its technical problem adopts: improve a kind of Cylinder Plunger head being provided with wear-resistant sleeve, comprise plunger rod and plug, described plug is fixedly connected with one end of plunger rod, the middle part of described plug has mounting hole, be close to mounting hole inwall and be provided with wear-resistant sleeve, described wear-resistant sleeve is arranged in mounting hole by shrinkage method, and the thickness of described wear-resistant sleeve is 10mm, and material is the Bearing Steel of using plasma seepage flow technology.
beneficial effect
Compared with prior art, the utility model has the following advantages:
1. the utility model is transformed into by the combined column chock plug that high-strength wearable overlaps and fine finishing plug two pieces is assembled by the plug of former one, and processing is simple, is easy to realize.
2. the utility model effectively reduces the wearing and tearing of large_sized hydraulic cylinder plug, thus working life is extended, and can also be improved the working life of cylinder plunger simultaneously further, greatly reduce expense by the method changing high-strength wearable cover.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1. plunger rod; 2. plug; 3. wear-resistant sleeve; 4. mounting hole
Embodiment
Below in conjunction with specific embodiment, set forth the utility model further.Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the utility model instruction.
As shown in Figure 1, mode of execution of the present utility model relates to a kind of Cylinder Plunger head being provided with wear-resistant sleeve, comprise plunger rod 1 and plug 2, described plug 2 is fixedly connected with one end of plunger rod 1, mounting hole 4 is had in the middle part of described plug 2, be close to mounting hole 4 inwall and be provided with wear-resistant sleeve 3, described wear-resistant sleeve 3 is arranged in mounting hole 4 by shrinkage method, the thickness of described wear-resistant sleeve 3 is 10mm, when being connected with large hydraulic cylinder plug, described wear-resistant sleeve 3 can ensure the safe bearing load of plug 2, the Security that it uses can not be affected, on the contrary, wear-resistant sleeve 3 is not originally installed, after large_sized hydraulic cylinder uses a period of time, the mounting hole 4 of plug 2 can wear and tear or scratch, if continuing to use just exists potential safety hazard again, very large impact is caused on production, therefore, this wear-resistant sleeve 3 has been installed, not only eliminate the potential safety hazard that large_sized hydraulic cylinder Long-Time Service produces because plug 2 weares and teares, but also substantially increase the working life of plug 2, whole Cylinder Plunger head will be scrapped after wearing and tearing by plug 2 originally, waste very much, and the plug 2 having installed wear-resistant sleeve 3 can change wear-resistant sleeve 3, whole plug can not be scrapped, and the material of wear-resistant sleeve 3 is the Bearing Steel of using plasma seepage flow technology, obviously, the cost of wear-resistant sleeve 3 is well below whole plug, and wear-resistant sleeve 3 is more wear-resisting than plug 2, by contrast, the plug 2 having installed wear-resistant sleeve 3 saves expense greatly, also very safe and reliable in process of production.
