Description
Technical field
The present invention relates to stamping end socket quality detection technology, and in particular to a kind of stamping end socket amount of plastic deformation
Measuring system and method.
Background technology
With national clean energy resource implementation, the clean energy resource demand growth such as domestic liquefied natural gas (LNG) is rapid,
One of the main warehousing and transportation facilities of austenitic stainless steel (such as S30408) deep cooling container as LNG, its demand is also increasing.Envelope
One of the core component of head as deep cooling container, its property relationship carries to the safe to use of container products, therefore to end socket quality
Higher requirement is gone out.Process for stamping and forming is universal because of the advantages that its machining accuracy is high, surface quality is good, production efficiency is high
It is stamping such as end socket for the manufacture of middle-size and small-size deep cooling container.
However, during austenitic stainless steel head pressing, due to deformation-induced martensitic transformation, excessive plasticity becomes
Shape causes end socket (especially straight section) to produce substantial amounts of martensite.And martensitic phase is high compared with austenite phase hardness, fragility is big, and
There is obvious facilitation to stress corrosion, so as to influence end socket military service performance, end socket Cracking Failure may be caused when serious, is deposited
In potential safety hazard.Research finds corresponding relation be present between martensite content and plastic deformation, can be become by limiting excessive plasticity
Shape controls deformation induced martensite content.Therefore, accurate measurement is carried out with important engineering meaning to the amount of plastic deformation of end socket
Justice.
At present, there is many limitations in domestic the end socket plastic deformation measuring system used and method.The first is by making
Made marks with oiliness or free ink pen line, the distance between each mark point of end socket sheet-metal press working fore-and-aft survey, so as to obtain
Plastic deformation before and after head pressing, this method use range is most wide, and operating flexibility is high, but artificial crossed efficiency is low, time-consuming
Arduously, and mark easily fogs and lost after plate lubrication, influences reading, practicality is not high；
Second, be that on end socket surface, line is marked by using the methods of (starting or manual) draw point or electrochemical corrosion
Note, then the distance between each mark point before and after end socket sheet-metal press working is measured, so as to obtain the plastic deformation before and after head pressing,
This method use range is wider, and mark is more visible, but scratch depth is difficult to control, can influence end socket surface property (such as roughness,
Decay resistance etc.), it is unfavorable for Improving The Quality of Products, and draw point of ruling is easily-consumed products, use cost is high, artificial crossed efficiency
It is low；

Positioning and marking device on end socket surface, efficiency high, the positioning precision of the line of these devices are good, but cut can destroy end socket table
Face integrality, while apparatus structure is more complicated, installation measuring process is cumbersome；
Further, it is that it is on determinand surface by using the method for laser scanning non-cpntact measurement pressure vessel deflection
Circular markers are carried out, deformation data, this method are obtained by the space coordinates and calculating of determinand before and after measurement deformation
Measurement efficiency is high, precision is high, but laser measuring apparatus input cost is high, simultaneously for stamping end socket, due to blank holder,
The squeezing action of punch-pin and cavity plate, easily make the label loss at (deflection is big) position near head skirt section, so as to deformation measurement
Amount can not be carried out, and overall adaptability is not high.In addition, the optical gauge such as large laser scanner use condition is harsh, measurement
Precision is easily by such environmental effects such as flue dust, haze, illumination, vibrations, and practicality is by larger limitation.
Further, Chinese patent CN103353296A discloses a kind of by measuring martensite content (FN before and after end socket deformation
Number) method predict the method for amount of plastic deformation before and after seal head forming, this method belongs to indirect measurement, it is convenient, fast that it is measured
Speed, service efficiency is high, but the degree of accuracy is not high, and its precision depends on martensitic phase variable and end socket housing, the transition established early stage
With the validity of the relation curve of straight section deformation quantity, and ferrite measuring instrument is expensive, and input cost is higher.
In a word, it is conventional at present such as using oil pen, draw point, multiaxis positioning marking, laser scanning, martensitic phase variable side
Method measures the device or method of end socket deflection, still suffers from many limitations, needs badly a kind of high-precision, highly reliable, inexpensive
