Abstract
The invention discloses an apparatus for making a pre-cracked sample for material mechanical properties test. The apparatus comprises a pedestal, a base plate is arranged at upper end of the pedestal, a model loop, a pre-cracked model, a positioning column and a positioning lock are arranged on the base plate, the pre-cracked model is fixed in the model loop in a movable mode, and the positioning column and the positioning lock are closely arranged at circumference of the model loop. The apparatus has the advantages of simple structure, less volume, and convenient operation; complexity of the experiment apparatus is reduced, production material is saved, making flow is indirectly simplified, and cost is saved. The used pre-cracked model substitutes a conventional cutter for cutting, pre-cracks quality can be increased, and abrasion of the used conventional cutter due to cutting on the sample and a cutter can be avoided.
Description
Technical field
The present invention relates to the producing device of the pre-precracked specimen of band of a kind of material mechanical performance test.
Background technology
Tensile property is the important mechanical property of of material, and it is widely used in the middle of various engineering field, and the test way of material extending mechanical property has multiple, and corresponding sample also has many types, such as, and right cylinder, beam, Brazilian disc etc.; The preparation facilities of sample has cylinder, rectangle box, and for the annular cutter of Brazilian disk specimen; The preparation of pre-crackle is also mainly cut with cutter.But these experimental provisions are complicated, consumptive material is large, make trouble, when the particulate matter of compound substance is excessive time, the pre-crackle that cutter cutting produces is also often not ideal enough, and cutter easily damages, the producing device of the pre-precracked specimen of band therefore needing a kind of novel material mechanical performance to test.
Summary of the invention
The present invention is directed to the producing device of the pre-precracked specimen of band that the deficiencies in the prior art provide a kind of material mechanical performance to test, object solves existing experimental provision complexity, consumptive material is large, time the particulate matter of making trouble and compound substance is excessive, the pre-crackle that cutter cutting produces is also often not ideal enough, and cutter holds flimsy problem.
The present invention is for realizing above object, adopt following scheme: a kind of producing device of the pre-precracked specimen of band of material mechanical performance test, comprise base, described base upper end is provided with base plate, described base plate is provided with model circle, pre-crack model, reference column and positioning lock, it is inner that described pre-crackle model activity is fixed on model circle, described reference column and positioning lock is adjacent is arranged on model circle periphery.
Preferably, described model circle is formed by rectangle folding of material, and the folding gap at its rectangle material two ends is model circle gap, and described model circle gap is solid by scalable locking.
Preferably, described pre-crack model height is higher than described model circle height.
Preferably, described reference column is plugged in the pilot hole on base and base plate, and described positioning lock activity is plugged in the lockhole on base plate.
Preferably, described positioning lock is made up of the right cylinder that two diameters are different, and its upper end is the right cylinder that diameter is larger, and its lower end is the right cylinder that diameter is less, wherein comparatively large cylinder end face is provided with rotating gravure, and less right cylinder deflection is arranged on comparatively side, large cylinder bottom surface.
Preferably, described base plate is smooth flat, and described model circle inwall is smooth surface.
Beneficial effect of the present invention:
1, structure of the present invention is simple, and small volume is easy to operate, decreases the complicacy of experimental provision, saves manufactured materials, indirectly simplify Making programme, cost-saving.
2, the pre-crack model replacement conventional knife that arranges of the present invention cuts, and improves the quality of pre-crackle, avoids the wearing and tearing using conventional knife cutting and then bring sample and cutter.

Fig. 2 is structure vertical view of the present invention;
Fig. 3 is positioning lock structural representation of the present invention.
Embodiment
A kind of producing device of the pre-precracked specimen of band of material mechanical performance test as illustrated in the drawing, comprise base 2, described base 2 upper end is provided with base plate 3, described base plate 3 is provided with model circle 7, pre-crack model 8, reference column 1 and positioning lock 6, it is inner that described pre-crack model 8 is movably fixed to model circle 7, described reference column 1 and positioning lock 6 is adjacent is arranged on model circle 7 periphery, described model circle 7 is formed by rectangle folding of material, the folding gap at its rectangle material two ends is model circle gap 4, described model circle gap 4 is fastening by scalable lock 5, described pre-crack model 8 height is higher than described model circle 7 height, described reference column 1 is plugged in the pilot hole on base 2 and base plate 3, the activity of described positioning lock 6 is plugged in the lockhole on base plate 3, described positioning lock 6 is made up of the right cylinder that two diameters are different, its upper end is the right cylinder that diameter is larger, its lower end is the right cylinder that diameter is less, wherein comparatively large cylinder end face is provided with rotating gravure, less right cylinder deflection is arranged on comparatively side, large cylinder bottom surface, it is characterized in that, described base plate 3 is smooth flat, described model circle 7 inwall is smooth surface.
Embodiment, first close scalable lock 5 and the conjunction of model circle crackle 4 is closed, then be placed on base plate 3 by adjacent for model circle 7 two reference columns 1, grafting positioning lock 6 in lockhole also rotates the fixing of positioning lock 6 implementation model circle 7.Then sample is put into model circle 7, and whole model to be put among the condition required for experiment (such as, when sample is concrete time, whole model can be placed on vibration table and vibrate).After sample consolidation has been got well, positioning lock 6 has been opened in turn, then reference column 1 and positioning lock 6 can be taken out.Open scalable lock 5, now model circle crackle 4 has opened, and between sample and smooth model circle inwall, cohesive force reduces, and is taken out by model circle 7.Because pre-crack model 8 is higher than sample, user can use object surely to live sample (such as with hand-held), then with the thing of rubber hammer and so on, can beat pre-crack model 8 gently, and then be taken out by sample, complete whole process.
