The assembled and filled thermally induced pressure device is characterized in that the fastening piece is a circular sleeve of a certain thickness, the filling block consists of a middle filling block and two auxiliary filling blocks respectively positioned on both sides of the middle filling block and the three filling blocks constitute an integral cylinder and are installed inside the fastening piece through an interference fit, wherein, the longitudinal sections of the middle filling block and the two auxiliary filling blocks are close to each other and parallel to each other as well asparallel to the axle center of the fastening piece, the middle section of the middle filling block is provided with a horizontal round through-hole penetrating the axle center of the fastening piece vertically, the cylindrical sample is installed inside the through-hole through an interference fit, both ends of the sample closely contact the two auxiliary filling blocks respectively positioned on both sides of the middle filling block, and the coefficient of thermal expansion for the sample is larger than the coefficient of thermal expansion for the filling block. The assembled and filled thermally induced pressure device can produce a high pressure spontaneously without any help from an external force and has a compact structure applicable to materials with a relatively large radial dimension. In addition the price is low, the assembly is easy and the sample is easy to be removed at the end of an experiment.
Description
Technical field
The utility model provides a kind of assembling filled type thermic pressure apparatus, belongs to manufacture and design high pressure and extra-high tension unit technical field.
Background technology
The existing device that produces high pressure mainly contains the pressure anvil (anvil) that the cubic apparatus that uses on the engineering and top, two sides equipment and laboratory research are used.The basic principle of these equipment all is by the external force work done, make the inner high-pressure environment that produces of die cavity, wherein the advantage of cubic apparatus and top, two sides equipment is that die cavity is bigger, can satisfy the requirement of Φ 30～50mm cavity size, be applicable to industrial production, but equipment volume is huge, weighs tens tons certainly, and the pressure that produces is less, generally has only～10GPa; Press anvil can produce pressure greater than 100GPa, and install lessly, but that its shortcoming is a mold cavity volume is minimum, only is 10
-4Mm
3The order of magnitude.The high pressure of existing equipment produces principle and has determined mold cavity volume and high pressure not to take into account, and therefore utilizes present high-tension apparatus can't realize cm
3The order of magnitude, the above hyperbaric environment of 10GPa.
In order to overcome the deficiency that above-mentioned high pressure generating apparatus exists, application number has proposed to come based on principle of expanding with heat and contracting with cold the thinking of design pressure generation device for the application for a patent for invention of " 200610166214 ", do not rely on the direct work done of external force, utilize the difference of different materials thermal coefficient of expansion, under hot conditions,, be implemented in cm because of volume can not free wxpansion produce pressure
3Produce the above hyperbaric environment of 10GPa in the order of magnitude mold cavity volume, but this contrive equipment is applicable to axial length, the sample of radially lacking.
The utility model content
The purpose of this utility model provides a kind ofly can overcome above-mentioned defective, make surface to volume ratio less relatively, help improving die cavity pressure inside value, be applicable to the assembling filled type thermic pressure apparatus of handling the bigger sample of radial dimension.Its technical scheme is:
Comprise sample, securing member and filling block, it is characterized in that: securing member is for having certain thickness circular sleeve, the secondary filling block of filling block both sides in the middle of filling block and the separation in the middle of filling block comprises, three filling blocks constitute the complete circle cylinder and interference is installed in the securing member, vertical tangent plane that filling block and two secondary filling blocks are close in twos wherein is parallel to each other, and the axle center that is parallel to securing member, have the horizontal manhole that vertically passes the securing member axle center at the middle part of middle filling block, cylindric sample interference is installed in the manhole, its two ends closely contact with the secondary filling block of separation in middle filling block both sides, and the thermal coefficient of expansion of sample is greater than the thermal coefficient of expansion of securing member and filling block.
Described assembling filled type thermic pressure apparatus, vertical tangent plane that middle filling block and two secondary filling blocks are close in twos is a high precision plane.
Its operation principle is: the difference of utilizing the different materials coefficient of thermal expansion and contraction, allow the thermal coefficient of expansion materials with smaller closely wrap up the bigger material of thermal coefficient of expansion, when integral body is heated, the material that the internal heat coefficient of expansion is big is subjected to closely parcel and can not free wxpansion of the little material of thermal coefficient of expansion, thereby produces pressure when being heated voluntarily; Heating-up temperature is high more, and the pressure that the material that the internal heat coefficient of expansion is big is subjected to is also just big more.The thermal coefficient of expansion of sample is greater than the thermal coefficient of expansion of device materials on every side in the design, and in the manhole at filling block middle part, the expansion radially of sample this moment will be restricted in the middle of cylindric sample interference fit is installed in, but but its axially still free wxpansion; Be equipped with secondary filling block again, simultaneously in the middle of filling block and two secondary filling blocks constitute the complete circle cylinders, be interference fit with the endoporus of securing member, then the axial expansion of sample also is restricted; Like this sample under the situation of being heated its radial and axial all can not free wxpansion, therefore under hot conditions, will produce big pressure voluntarily.
The utility model compared with prior art has following advantage:
1, under hot conditions, produce high pressure voluntarily, fully need be by external force; The structural design compactness is applicable to the bigger material of radial dimension;
2, used securing member and filling block material price are cheap, and the device each several part is easy to machined, and package unit assembles easily, after the off-test, takes out sample easily.
3, the new equipment manufacturing cost is lower, is suitable for the variation of laboratory research material various structure properties after hyperbaric environment is handled.
