Abstract
The utility model discloses a sample preparation die for preparing spectral analysis samples. The sample preparation die comprises an upper pressure plate, clamp plates, a lower pressure plate and an electric heating sheet which are sequentially arranged from top to bottom, wherein the four clamp plates are arranged, the four clamp plate and the upper pressure plate as well as the lower pressure plate commonly define a sample forming cavity for storing the samples; a positioning hole is formed in the lower pressure plate, and an elastic piece is arranged in the positioning hole; positioning pins adaptive to the positioning hole are also arranged at the bottom of the clamp plates. When the sample preparation die is adopted for pressing and forming molten-state samples, the samples of different specifications can be obtained by regulating the positions of the pressure plates and the positioning pins, the prepared sample have smooth surfaces, and no air bubbles inside, and are good in uniformity, furthermore, in pressing, the lower pressure plate is heated by the electric heating sheet at the bottom of the lower pressure plate, and the composition segregation of the molten-state samples due to temperature shock can be effectively prevented.
Description
Technical field
The utility model relates to a kind of sampling die, is specifically related to a kind of sampling die adopting while adopting fusion method to prepare spectrum analysis sample.
Background technology
Spectral analysis has powder pressing method and melting sample preparation method with the method for making sample of solid sample.Powder pressing method cost is low, speed is fast, easy to operate, be applicable to production control, shortcoming is that the print made of the method exists more serious grain effect, easily affects the accuracy of measurement result; Fusion method is to adopt fusion apparatus by compressing tablet again after raw materials melt, and the print making by the method is due to by melting, and thing obtains unified mutually, can overcome well granularity effect.
While adopting fusion method sample preparation, the sample of melting need to be cast straight in mould, the then rapid cooling sample of making, conventional mould has gravity casting mould and pressurization casting die.But, easily there is component segregation in existing gravity casting mould, can not pressurize in the time of Slow cooling, cause the sample surfaces made rough, easily there is bubble in inside, and then affects the accuracy of measurement of sample; And adopt pressurization when casting die, although the sample forming extruding, highly polished, due to gas penetration potential and poor radiation, easily causes sample to have crackle, bubble many, analysis result representativeness is poor.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, the sampling die that provides a kind of spectral analysis to use, and the sample that adopts this mould to make, smooth surface, sample interior be without bubble, good uniformity.
For achieving the above object, the utility model is by the following technical solutions:
A kind ofly prepare the sampling die that spectrum analysis sample is used, comprise the top board, clamping plate lower platen and the electric heating sheets that set gradually from top to bottom, wherein, described clamping plate are provided with four altogether, and four clamping plate and top board, lower platen surround the sample forming cavity for placing sample jointly; Described lower platen is provided with pilot hole, and is provided with elastic component in pilot hole; The bottom of described clamping plate is also provided with the register pin suitable with pilot hole.
Preferably: the bottom of described sample forming cavity is provided with a metal base plate;
Preferably: the thickness of described metal base plate is 1～3mm;
Preferably: described metal base plate has a smooth upper surface;
Preferably: described elastic component is spring;
Preferably: described pilot hole is provided with four groups altogether, be located at respectively lower platen four jiaos, and every group of pilot hole includes located lateral hole and longitudinal register hole;
Preferably: described located lateral hole and longitudinal register hole are arranged into " ten " font.
The beneficial effects of the utility model are, while adopting sampling die described in the utility model to be pressed to the sample of molten state, can obtain by adjusting the position of pressing plate and register pin the sample of different specification size, the sample surfaces making is smooth, inner noresidue bubble, good uniformity, and, in the time of compacting, the electric heating sheets of lower platen bottom heats lower platen, can effectively prevent that the sample of molten state is because component segregation occurs in temperature shock.
Brief description of the drawings
Fig. 1 shows the structural representation of sampling die described in the utility model;
Fig. 2 shows the side view of sampling die described in the utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
As shown in Figures 1 and 2, sampling die described in the utility model, comprise the top board 1 setting gradually from top to bottom, clamping plate 2, lower platen 6 and electric heating sheets 7, wherein, described clamping plate 2 are provided with four altogether, and four clamping plate 2 and top board 1, lower platen 6 surrounds the sample forming cavity 8 for placing sample jointly, further, for avoiding sample directly to contact with lower platen 6, can arrange one suitable with the bottom surface of sample forming cavity 8 in the bottom of sample forming cavity 8, the base plate 3 that preferred metal materials is made, and the thickness of described base plate 3 is 1～3mm, the upper surface of base plate 3 is the surface through polishing, to ensure the ganoid of sample after moulding, described lower platen 6 is provided with many group pilot holes 4, and in pilot hole 4, being provided with is for example the elastic component 5 of spring, in the present embodiment, described pilot hole 4 is provided with four groups altogether, be located at respectively lower platen 6 four jiaos, and every group of pilot hole 4 includes located lateral hole and longitudinal register hole, and described located lateral hole and longitudinal register hole are arranged into " ten " font, in addition, the bottom of described clamping plate 2 be also provided with position adjustable, with the suitable register pin (not shown) of pilot hole 4.
Sampling die of the present utility model, its using method is: according to needed sample specification, adjust the position of clamping plate 2 and register pin, and fixing by the pilot hole 4 on register pin and lower platen 6, the sample forming cavity 8 that clamping plate 2, top board 1, lower platen 6 are surrounded is suitable with required sample specification, then, by in the Sample introduction sample forming cavity 8 after melting plant melting, cover top board 1, with sheeter (or other press device), top board 1 is exerted pressure, make sample compressing in sample forming cavity 8.Wherein, in pressing process, in the time that top board 1 pressurized is suppressed sample downwards, under the acting in conjunction of register pin and pilot hole 4 inner springs, pressing plate 2 presses down to 3 thereupon, thereby the sample in sample forming cavity 8 is fully pushed, effectively to get rid of the bubble in sample; Meanwhile, in pressing process, the electric heating sheets 7 of lower platen 6 bottoms heats lower platen 6, can effectively prevent that the sample of molten state is in the time of compacting, because component segregation occurs in temperature shock.
Be only the utility model preferred embodiment in sum, be not used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modify, all should belong to technology category of the present utility model.
