Description
Technical field
The present invention relates to a kind of producing devices of the pre- precracked specimen of band of material mechanical performance test.
Background technology
Tensile property is an important mechanical property of material, is widely used in various engineering fields, material
There are many test methods of tensile mechanical properties, and also there are many kinds of classes for corresponding sample, for example, cylinder, beam, Brazilian disc
Deng；The preparation facilities of sample has cylinder, rectangle box, and the annular cutter for Brazilian disk specimen；The system of pre- crackle
It is standby also mainly to be cut with cutter.But these experimental provisions are complicated, consumptive material is big, trouble is made, when the particulate matter of composite material
When matter is excessive, pre- crackle caused by cutter cutting also tends to not ideal enough, and cutter is easily damaged, it is therefore desirable to one
The producing device of the pre- precracked specimen of band of the novel material mechanical performance test of kind.
Invention content
The present invention provides a kind of making of the pre- precracked specimen of band of material mechanical performance test in view of the deficiencies of the prior art
Device, it is therefore an objective to solve that existing experimental provision is complicated, and consumptive material is big, make trouble and composite material particulate matter it is excessive when
It waits, pre- crackle caused by cutter cutting also tends to not ideal enough, and the problem of cutter is easily damaged.
The present invention is in order to achieve the above object, using following scheme：A kind of pre- precracked specimen of band of material mechanical performance test
Producing device, including pedestal, the pedestal upper end is equipped with bottom plate, and the bottom plate is equipped with model circle, pre- crack model, positioning
Column and positioning lock, the pre- crackle model activity are fixed on inside model circle, and the positioning column and positioning lock are closely arranged
Model circle periphery.
Preferably, the model circle is formed by rectangle folding of material, and the folding gap at rectangle material both ends is mould
Type circle gap, model circle gap are solid by scalable locking.
Preferably, the pre- crack model height is higher than the model circle height.
Preferably, the positioning column is plugged in the location hole on pedestal and bottom plate, and the positioning lock activity is plugged on bottom
In lockhole on plate.
Preferably, the positioning lock is made of two different cylinders of diameter, and the upper end is the cylinder being relatively large in diameter,
Its lower end is the smaller cylinder of diameter, wherein larger cylinder top surface is equipped with rotating gravure, smaller cylinder is biased to setting
In larger cylinder bottom surface side.
Preferably, the bottom plate is smooth flat, and the model circle inner wall is smooth surface.
Beneficial effects of the present invention：
1, the configuration of the present invention is simple, small volume is easy to operate, reduces the complexity of experimental provision, saves manufacture
Material simplifies production process indirectly, cost-effective.
2, the pre- crack model of setting of the invention is cut instead of conventional knife, improves the quality of pre- crackle, avoiding makes
The abrasion cut with conventional knife and then sample and cutter are brought.
Description of the drawings
Fig. 1 is schematic structural view of the invention；
Fig. 2 is structure of the invention vertical view；
Fig. 3 is positioning lock structural schematic diagram of the present invention.
Specific implementation mode
A kind of producing device of the pre- precracked specimen of band of material mechanical performance test as illustrated in the drawing, including pedestal 2, institute
It states 2 upper end of pedestal and is equipped with bottom plate 3, the bottom plate 3 is equipped with model circle 7, pre- crack model 8, positioning column 1 and positioning lock 6, institute
Pre- crack model 8 to be stated to be movably fixed to inside model circle 7, the positioning column 1 and positioning lock 6 are closely arranged on 7 periphery of model circle,
The model circle 7 is formed by rectangle folding of material, and the folding gap at rectangle material both ends is model circle gap 4, described
Model circle gap 4 is by 5 fastening of scalable lock, and 8 height of pre- crack model is higher than 7 height of the model circle, the positioning
Column 1 is plugged in the location hole on pedestal 2 and bottom plate 3, and 6 activity of the positioning lock is plugged in the lockhole on bottom plate 3, described fixed
Position lock 6 is made of two different cylinders of diameter, and the upper end is the cylinder being relatively large in diameter, and lower end is the smaller circle of diameter
Cylinder, wherein larger cylinder top surface is equipped with rotating gravure, smaller cylinder is biased to be arranged in larger cylinder bottom surface side,
It is characterized in that, the bottom plate 3 is smooth flat, 7 inner wall of model circle is smooth surface.
Embodiment is first shut off scalable lock 5 so that model circle crackle 4 closes closes, then by closely two positioning columns of model circle 7
1 is placed on bottom plate 3, the fixation of grafting positioning lock 6 and rotational positioning 6 implementation model circles 7 of lock in lockhole.Then sample is put
Enter in model circle 7, and entire model is put among the required condition of experiment (for example, when sample is concrete, it can
It is vibrated so that entire model to be placed on vibration table).After sample has consolidated, positioning lock 6 is opened in turn, then can will be determined
Position column 1 and positioning lock 6 take out.Scalable lock 5 is opened, model circle crackle 4 opens at this time, sample and smooth model circle inner wall
Between cohesive force reduce, model circle 7 is taken out.Since pre- crack model 8 is higher than sample, user can use object to live to try surely
Sample (such as being held with hand) then can use the thing of rubber hammer etc, gently beat pre- crack model 8, and then sample is taken
Go out, completes whole process.
