Abstract
A composite cylinder jacket is featured as using alloy cast - iron layer as internal layer of cylinder jacket and using cast - steel layer as external layer, setting pure copper combination layer between alloy cast - iron layer and cast - steel layer for connecting these two layers. Its preparing method is the same to cold processing technology, heating and chemical treatment technique and outline size in method for preparing universal cylinder jacket in addition to casting technique.
Description
Technical field
The present invention relates to a kind of air cylinder sleeve of engine.
Background technique
Existing internal-combustion engine wet liner mostly is cast iron materials, and its shortcoming is that fragility is big, in use, crackle and broken situation often occur, causes a serious accident easily; The advantage of cast iron materials is a good manufacturability, and is wear-resistant, can process platform reticulate pattern at inwall, helps like this shortening running-in period, can retain a certain amount of lubricant oil during machine works in reticulate pattern, good lubricating condition is provided for the normal operation of machine.The cylinder liner that also has uses material to be steel, and its advantage is a good reliability, is not easy to crack and fracture defect, and shortcoming is that manufacturability is poor, and processing cost height, inwall are difficult to process platform reticulate pattern, the store oil ability, and lubrication circumstances is bad.
Summary of the invention
Thereby technical problem to be solved by this invention provides a kind of reliability and wear resistance that improves cylinder liner to be prolonged its working life, stops the composite cylinder jacket that accident takes place.
Another technical problem to be solved by this invention provides the method for making described composite cylinder jacket.
For achieving the above object, technological scheme of the present invention is: a kind of composite cylinder jacket, the internal layer of described composite cylinder jacket are the alloy cast iron layer, and skin is the cast steel layer, are the fine copper binder course that connects alloy cast iron layer and cast steel layer between alloy cast iron layer and the cast steel layer.
As a kind of improvement, the inwall of described alloy cast iron layer is processed with platform reticulate pattern.
As a kind of improvement, the outer wall of described cast steel layer is provided with chromium coating.
Make the method for described composite cylinder jacket, may further comprise the steps:
At first cast, process cylinder liner internal layer one alloy cast iron layer, processed the positive and negative spiral chute of fixation then at the outer wall of alloy cast iron layer, then electroplate or the spraying pure copper layer at the outer wall of alloy cast iron layer, the purpose of laying pure copper layer is for alloy cast iron and better combination infiltration of cast steel; After these work were carried out, at the outer wall casting cast steel layer of alloy cast iron layer, in the casting process, pure copper layer melted infiltration thereupon, forms binder course, and alloy cast iron layer and cast steel layer are combined closely again, and the blank of composite cylinder jacket has just completed like this; Remaining cold machining process and heat, chemical treatment technology and boundary dimension are just the same with common alloy cast iron cylinder jacke, can process qualified cylinder liner.
The utility model composite cylinder jacket has been concentrated all advantages of cast iron cylinder cover and steel cylinder liner, abandoned the shortcoming of the two, except that changing casting technique, other cold working and heat, chemical treatment technology and boundary dimension can make full use of existing process equipment and process with general cylinder liner; In use, this composite cylinder jacket has good rigidly, characteristics that toughness is high, can significantly improve fatigue resistance, thoroughly solves the fracture of cylinder liner problem; And it is wear-resistant, adopt international advanced platform reticulate pattern honing technique to process platform reticulate pattern, during machine run in cylinder liner rubbing surface reticulate pattern, can store a certain amount of lubricant oil, cast iron contains a certain amount of graphite in addition, thereby guarantees proper lubrication, the possibility of reduce scuffing of cylinder bore, embracing cylinder, reduce frictional force, realization internal-combustion engine high efficiency is reliably exported.
Description of drawings
Accompanying drawing is the structural representation of the embodiment of the invention.
Embodiment
As shown in drawings, a kind of composite cylinder jacket, the internal layer of described composite cylinder jacket are alloy cast iron layer 1, and skin is a cast steel layer 3, are the fine copper binder course 2 that connects alloy cast iron layer 1 and cast steel layer 3 between alloy cast iron layer 1 and the cast steel layer 3.The inwall of described alloy cast iron layer 1 is processed with platform reticulate pattern 4, has improved the store oil ability of cylinder liner greatly, has improved lubricating between cylinder liner and the piston.
The outer wall of described cast steel layer 3 is provided with chromium coating, can prevent the corrosion of cylinder liner outer wall, improves the working life of cylinder liner.
Make the method for described composite cylinder jacket, may further comprise the steps:
At first cast, process cylinder liner internal layer one alloy cast iron layer 1, processed the positive and negative spiral chute of fixation then at the outer wall of alloy cast iron layer 1, then electroplate or the spraying pure copper layer at the outer wall of alloy cast iron layer 1, the purpose of laying pure copper layer is for alloy cast iron and better combination infiltration of cast steel; After these work were carried out, at the outer wall casting cast steel layer 3 of alloy cast iron layer 1, in the casting process, pure copper layer melted infiltration thereupon, forms binder course 2, and alloy cast iron layer 1 and cast steel layer 3 are combined closely again, and the blank of composite cylinder jacket has just completed like this; Remaining cold machining process and heat, chemical treatment technology and boundary dimension are just the same with common alloy cast iron cylinder jacke, can process qualified cylinder liner.
Alloy cast iron layer 1 used material of the present invention follows the material of existing cast iron cylinder cover identical.And can make full use of existing process equipment and frock measurer etc., can process platform reticulate pattern 4 easily; Guaranteed the usage requirement of internal combustion engine wet liner harshness.
