The embodiment of the present invention is described in detail with reference to the accompanying drawing.
Diesel engine of diesel locomotive valve is the component part of combustion chamber, and forms gas into and out of the logical of combustion chamber with cylinder body
Road, the main function of valve are responsible for inputting fuel into engine and exhaust gas are discharged, and the quality of quality directly influences interior
The operation of combustion locomotive, the failure of diesel engine of diesel locomotive valve frequently result in diesel engine of diesel locomotive failure, cause locomotive operation
The quality of accident, valve discone antenna surface is particularly important, as railway transportation develops towards high-speed overload direction, diesel engine of diesel locomotive
The working environment of valve discone antenna surface is more and more severe, therefore the probability that the position is broken down is very big, and the general built-up welding of discone antenna surface
Cobalt base superalloy, the hardness of discone antenna surface are the important detection projects of valve, and regulation must in diesel engine of diesel locomotive valve standard
Hardness determination must be carried out to valve discone antenna surface.
There are mainly two types of the methods of existing detection hardness of conical surface of valve retainer, and one is examined on Rockwell apparatus
It surveys, since the detection platform of Rockwell apparatus has surface platform and two kinds of V-type platform, and valve discone antenna surface can not be directly applied for
Both platforms go test hardness, and the scheme of existing use is that the method dissected valve is tested, i.e., is cut using line
Cutting mill cuts the bottom surface Rockwell hardness detection sample parallel with valve discone antenna surface at valve discone antenna surface, then in Rockwell apparatus
The shortcomings that progress Rockwell hardness inspection on the surface platform of itself, this kind of method of inspection, is:
Since this kind of Rockwell hardness method of inspection belongs to destructive testing, diesel engine of diesel locomotive valve material therefor in addition
Sufficiently expensive, manufacturing process is very complicated, and valve finished product price is more expensive, therefore carries out hardness of conical surface of valve retainer inspection using this kind of method
Waste caused by survey is extremely serious, extremely uneconomical.Furthermore valve discone antenna surface size is smaller, and shape is lack of standardization, wire cutting can only be used
Machine-cut is materialsed, but the molybdenum filament of wire cutting machine is expensive, and process is easy fracture of wire, to operator quality and technical requirements compared with
Height, thus this processing method processing charges is big, and experimentation cost is caused to increase.In addition, the process velocity of wire cutting machine is very slow, examination
Sample long processing time, thus it is long using the method test period of wire cutting machine inspection by sampling, easily delay production.
The method of existing another detection hardness of conical surface of valve retainer is to be tested using the Leeb Hardness Tester of portable,
The advantages of this method is to examine convenient and efficient, at low cost, no waste.Lee ' hardness method is rushed using the carbide of definite quality
Body is hit under certain resilient force, with the method that certain velocity shock specimen surface carries out hardness measurement, test result
It is indicated with the ratio of rebound velocity of the formed punch at specimen surface 1mm and impact velocity multiplied by 1000.Such Hardness Surveillance
Method belongs to dynamic check method, more demanding to sample, it is desirable that specimen surface roughness is small, and has certain thickness.It examines
Valve will be intimately associated with the platform of more stable and stronger in the process, since valve retainer cone-shaped is lack of standardization and size is smaller, in addition in
The characteristics of family name's hardness determination itself, this kind of method of inspection error is larger, is suitble to the general control of production scene to examine, as routine
The method of inspection have certain limitation.
In order to improve the testing accuracy of valve discone antenna surface, meanwhile, destructive testing, the present invention are not carried out to valve discone antenna surface
A kind of new method of inspection is proposed, this programme is described in detail below by way of different embodiments:
