Description
Technical field
The invention belongs to metal material constant load stress corrosion (cracking) test technical field, be specifically related to frame-type constant load stress
Corrosion testing apparatus, by large-scale rigid supporting frame, can test for various sizes of sample.
Background technology
In daily production environment, corrosion phenomenon is seen everywhere, and the material failure caused because of corrosion can be found everywhere；Stress
Corrosion refers to by rupture process of material produced by stress and corrosion synergy, the as easy as rolling off a log calamity causing absence of aura of stress corrosion
Difficult sexual behavior therefore, therefore carry out study of stress corrosion testing to ensuring safety in production, to improve production efficiency significant.
At present, the stress corrosion testing device of use is to add constant load, prior testing elastic by O type elastic stress circulating application
The load displacement curve of ring, according to the change in displacement in process of the test, the load that estimation is applied on sample.Above-mentioned test fills
Putting, error is very big, and specimen size size is restricted.Along with the development of industrial technology, the corrosion resistance to material
Improving constantly, the requirement to corrosion test technique also improves constantly, and is thus necessary to upgrade at original assay device,
To improve test accuracy, meet the technology requirement of development.
Summary of the invention
For overcoming above-mentioned the deficiencies in the prior art, it is an object of the invention to provide a kind of frame-type constant load stress corrosion examination
Experiment device,
Overcome original stress corrosion testing device deficiency functionally；Have simple in construction, test accuracy is high, controllability is good, number
According to can acquisition monitoring, the feature of different sizes and shapes can be met.
For achieving the above object, the technical solution used in the present invention is: frame-type constant load stress corrosion testing device, bag
Having included base, base is provided with supporting frame；Corrosion vessel it are provided with in supporting frame；Corrosion vessel top is provided with load sensing
Device；Load transducer is connected to the top of supporting frame by screw rod, is provided with dish-like bullet between supporting frame and standby jack panel
Spring group.
It is provided with less friction packing ring between described disk spring group and nut.
Described disk spring group is in series by 4 disk springs.
The size of described supporting frame is 550mm × 260mm.
The invention has the beneficial effects as follows: add large scale supporting frame, by sample, the container of corrosive liquids, sensing
Within device is series at framework.Supporting frame is a rigid member, and material therefor is the 45# steel of modifier treatment.Owing to stress is rotten
The corrosion test time is longer, and supporting frame is in process of the test, it is impossible to have plastic deformation.Load transducer uses pillar pull sensing
Device, two ends use threaded, and this can make connection reliably facilitate, and easily, precision is high in dismounting.Dead load is applied by disk spring group
Lotus, disk spring group is in series by 4 disk springs, the global stiffness of serial spring group be each spring rigidity geometry it
With.Less friction packing ring, this packing ring particular design to be had, upper and lower two panels, centre is increased between disk spring and pre-load nut
Having thrust ball bearing support, when screw thread pair pretension, owing to pretightning force is bigger, between packing ring and pre-load nut, frictional force is wanted
Little, this special design makes frictional force less, and can bear bigger axial load.Standby tight spiral shell is connected by screw thread pair
Mother and sensor, this screw thread is made up of fine thread, and screw thread is M30 × 1, and fine thread lifting force is big, and self-locking property is good.
Present configuration is reasonable, simple to operate, easy for installation；Frame space is big, can be for different size, difform
Sample is tested；Disk spring group is replaceable, and trial stretch coverage rate is the widest.Add sensor, not only can be accurate
Ground applies predetermined initial trial load, it is also possible to the change procedure of load in monitoring test, greatly increases test accuracy,
Test data can be gathered, for judging that material property provides reliable basis simultaneously.

Described disk spring group is in series by 4 disk springs.
The size of described supporting frame is 550mm × 260mm.Frame size height is relatively big, can for different length or
The sample of shape is tested.
Permanent load is applied by disk spring group；Can be according to the different requirements of test, Design and Machining is various sizes of dish-like
Groups of springs so that test coverage rate is wider.
Increase load transducer, connect with sample；Test data can be gathered, be networked directly to controlling test computer.Carry
High test accuracy, makes the controllability of test, monitoring property be greatly improved.
The screw thread pair pitch of imposed load is less, and screw thread is M30 × 1.
Have employed less friction packing ring, it is characterized in that the screw thread vice division chief of imposed load and packing ring have less frictional force.
The operation principle of the present invention is:
By standby jack panel rotary motion on less friction packing ring, load to sample, by adding after making the deformation of disk spring group
Load framework supports；The power being carried on sample, is tested by load transducer；There is simple in construction, test accuracy height, controllability
Good, data can acquisition monitoring, the feature of different sizes and shapes can be met.
