Abstract
The invention discloses a two-pin magnetic probe detection sensor for a residual austenite content. The detection sensor comprises two magnetic detection pins used for detection the residual austenite content, two groups of coils used for transmitting signals, a round base provided with an aviation plug joint part, and a round through hole used for leading a coiled wire. The round base can be screwed on an aviation plug. A magnetized signal and a detection signal, which are carried on the coiled wire led from the round through hole, can form a relation curve capable of reflecting the residual austenite content of a ferromagnetic material. The detection sensor achieves the detection of the residual austenite content, and has the characteristics of high test accuracy, low measuring difficulty, short detection period, and a simple, convenient and flexible testing method. The detection sensor is capable of reaching any part of a ferromagnetic material object to be detected and carrying out nondestructive detection of the material and even carrying out the layered testing of the material.
Description
Technical field
The present invention relates to the retained austenite of ferrimagnet, more specifically say the bipod magnetic probe sensor that a kind of residual austenite content that is adapted to ferrimagnet detects.
Background technology
Austenite is a kind of phase of iron, and another kind is common is martensite mutually; Retained austenite refers to and occurs after martensite transfor mation, also has a small amount of austenite that transformation does not occur; In other words, retained austenite is to quench to fail to be transformed into martensite and remain into the austenite of room temperature;
Retained austenite has important impact to the mechanical property of material, physical property, shop characteristic.Appropriate retained austenite can be improved toughness, and anti-contact fatigue and low-temperature flexibility reduce structural stress and quenching distortion; But excessive residual austenite is known from experience reduction hardness, wearing quality; Very high to some sizes, stability requirement especially part, measurer and bearing, the existence of retained austenite can affect precision and life-span; Therefore detect residual austenite content and there is very important meaning to guaranteeing iron workpiece quality; Yet the detection of traditional retained austenite exists detection difficulty large, the shortcoming that sense cycle is long and testing cost is higher and method of testing are inconvenient.
Summary of the invention
The object of the present invention is to provide a kind of residual austenite content detecting sensor of bipod magnetic probe; It is low that it has detection difficulty, shortened sense cycle, thereby greatly reduce consumables cost the actual life of extension device, and method of testing is easy, guaranteed the feature of low-cost advantage simultaneously;
The object of the invention is to be achieved through the following technical solutions:
A kind of residual austenite content detecting sensor of bipod magnetic probe, it comprises: two magnetic that detect for residual austenite content are visited pin, the coiling of two groups of transmission of signals, and with the physa seat at aviation plug junction surface, also have a round tube hole that is used for drawing coiling;
Two magnetic visit on pin respectively around on one group of coiling, one of them is as magnetizing coil, another is as magnetic test coil; When magnetizing coil passes into, hand over after constant current, the magnetization signal magnetic field that can change, is placed on detected material visiting pin, just can on magnetic test coil, produce corresponding detection signal magnetic field,
Spy pin around upper coiling is grown on physa seat, physa seat further part is with aviation plug junction surface, aviation plug junction surface outside surface is helicitic texture (screw structural), described in that is to say, with the physa seat at aviation plug junction surface, can be screwed on the aviation plug (nut structure) of standard
In physa seat center, design a little round tube hole, be used for drawing coiling, and then both can input magnetization signal, can export again the detection signal of material;
Beneficial effect of the present invention is, the austenite content detecting sensor of described bipod magnetic probe is utilized the different of austenite and martensite magnetic characteristic in ferrimagnet, realized by the phenetic analysis to detection signal, the residual austenite content in ferrimagnet has been detected; This has not only reduced the difficulty detecting, and has shortened sense cycle, thereby has extended the actual life of equipment; And due to material is not damaged and reduced consumables cost, cost is lower.

Embodiment
Please refer to shown in Fig. 1,2, Fig. 1 is two-dimensional side view of the present invention; Fig. 2 is the two-dimentional vertical view of not coiling of the present invention; The residual austenite content detecting sensor 1 of described bipod magnetic probe comprises magnetic spy pin 2, coiling 3, the physa seat 4 with aviation plug junction surface, aviation plug junction surface 5, helicitic texture 6 and round tube hole 7; Wherein coiling 3 is visited on pin 2 for generation of magnetization signal and detection signal around magnetic; Magnetic is visited pin 2 and is grown on physa seat 4, and physa seat 4 further parts are with aviation plug junction surface 5, and aviation plug junction surface 5 outside surfaces are helicitic textures 6, can be screwed on the aviation plug of standard; In physa seat 4 centers, designed a little round tube hole 7, the coiling of coiling 3 can have been drawn, also just magnetization signal can have been imported, and the detection signal of generation is drawn;
Shown in Fig. 3, the residual austenite content detecting sensor 1 of described bipod magnetic probe is utilized the different of magnetic characteristic between ferrimagnet retained austenite and martensite, in coiling 3, utilize the marking current passing into produce magnetization signal, magnetic is visited to pin 2 to contact with measured material, material is magnetized, then
By coiling 3, the retained austenite detection signal in material is conducted out, by the phenetic analysis to detection signal, realized harmless, the efficient detection of the austenite content in ferrimagnet;
The residual austenite content detecting sensor of above-mentioned bipod magnetic probe has realized the detection of the austenite content in ferrimagnet, measuring accuracy is high, method of testing is easy, flexible, can reach any position of tested ferrimagnet object, and can carry out the nondestructive measurement of material, more can carry out zonation test to material.
