Description
Technical field
The present invention relates to a kind of analogue experiment installation and experimental technique thereof, particularly relating to a kind of similar materials mould assembly and the method for making analog material standard specimen thereof.
Background technology
Indoor physical simulation test is the important means of the motion of simulation Macroscopic physical field and Spatio-temporal Evolution.Wherein, the test of the mechanical property of analog material is the important indicator whether experimental material is suitable.
In prior art, the test mould making analog material standard specimen generally adopts split combination structure, in its use procedure, needs to use clip or other securing members to be tightened to one (finish using, loosening fasteners carries out the demoulding).But, after analog material filling, on pressing machine in loading procedure, due in the extruded process of analog material in inner chamber, by producing outside bulging force, often cause the play of clip or other securing members, and then the change causing experiment grinding tool inner chamber to mention, affect specimen molding effect, and then affect authenticity and the accuracy of subsequent experimental result.。
For solving above-mentioned ubiquitous technical matters, people have carried out the improvement of various securing member and fastening means, and achieve and to a certain degree improve.Wherein, so far, the most successfully example is, Chinese patent application CN103278360B discloses a kind of reserved chamber imitation specimen and prepares die assembly and the method for the preparation of test specimen thereof, it is dexterously by arranging the groove of band tapering in pairs in the outside wall surface of die assembly, adopting one between two grooves is the upper coarse and lower fine conical surface, another is the up-thin-low-thick conical surface, the first clip and the second clip is used to carry out fastening respectively at two grooves, wherein, the second clip inwall wears tapering; And first the diameter of external peripheral surface of clip be greater than the series technique means such as the diameter of the inner peripheral surface of the second clip, to make in mould sample under the pressure effect of pressing machine, its inner sample is by compression swelling, cause the second clip stressed on when altering, first clip also by due to after sample pressurized in mould crust to play downward under the effect of formwork shell periphery transmission of pressure, thus the acting force that generation one is downward, produced by the first clip and the second clip and act synergistically, mutual retaining, ensure that in formwork shell use procedure the stable state being in all the time and being clamped; Simultaneously, because clip causes clip to produce elastic deformation to peripheral direction transmission of pressure after sample pressurized, and exert pressure downwards along with pressing machine, clip elastic deformation amount is increasing, clip is therefore more swollen tighter, under the effect of the first clip and the mutual coordinated of the second clip, make the sample of formwork shell inside press tighter and tighter, press more closely knit and more closely knit.
But, blemish in an otherwise perfect thing, the reserved chamber imitation specimen of technique scheme prepares die assembly, and one is, the processing and manufacturing difficulty of the second clip is large, and cost is high; Two are, the dismounting of mould is relatively complicated, can not be suitable for the rapid shaping of batch test specimen; Three are, once occur that pressing machine on-load pressure is excessive to wait maloperation, are easy to cause two clips to damage.
Summary of the invention
An object of the present invention is, provide that a kind of structure is simple, form removal and the demoulding fast and simple, in sample loading process, its fastening effect stablizes firm, that specimen molding is effective similar materials mould assembly.
