Description
Technical field
The utility model relates to a kind of for testing the device of layer metal composite plate shearing strength, belongs to technical field of measurement and test.
Background technology
Dissimilar metal laminar composite is formed by two-layer or two-layer above metal composite of different nature; because it possesses the original not available good overall characteristic of each homogenous material, in fields such as Aero-Space, petrochemical complex, metallurgy, automobile, shipbuilding, electric power, medical and health, environmental protection, nuclear energy and household electrical appliance, be all with a wide range of applications.
The index of weighing composite metal plate quality good or not is a lot, common index has shearing strength, cohesive strength, conjugation, yield strength, tensile strength etc., wherein, shearing strength can illustrate the height of composite metal plate interface bond strength, so frequency of usage is the highest.Method of testing and the shear test equipment of layered metal composite plate shearing strength have relevant regulations in GB/T6396-2008.GB/T6396-2008 is in the regulation of shear test being divided into metal composite panel products two large classes: what composite plate gross thickness was less than or equal to 10 mm is greater than 10mm's with gross thickness.When composite plate gross thickness thinner (in standard regulation be less than or equal to 10mm), its matrix will occur bending and deformation under pressure, affect measuring accuracy, do not measure shearing strength value even completely, now GB GB/T6396-2008 regulation adopts and draws the mode of cutting to test shearing strength.But the method is only applicable to the relatively thick situation of multiple layer, and when multiple layer is thinner, its weakest position is easy to bend and rupture in drawing the process of cutting, and affects measuring accuracy, even makes test crash.Therefore, how to measure quickly and accurately the shearing strength of the thin specification composite plate that multiple layer is thinner, just become the difficult problem that relevant technologies personnel face.
Utility model content
The purpose of this utility model is the drawback for prior art, and a kind of layer metal composite plate shearing test device is provided, to measure quickly and accurately the shearing strength of the thin specification composite plate that multiple layer is thinner.
Problem described in the utility model realizes with following technical proposals:
A kind of layer metal composite plate shearing test device, formation comprises base, upper die and lower die, drift and gland, described drift and gland have identical rectangular cross section, gland is positioned at the below of drift and relative with drift, clamps the multiple layer of layer metal composite plate sample and connect by clamping screw between the two; The middle part of described counterdie and patrix is provided with the vertical through hole matching with gland and drift and by vertical through hole, slides over gland and drift outside respectively, clamps the basic unit of layer metal composite plate sample between the two; Between patrix and counterdie, by fastening bolt, be connected, counterdie is fixed on base top, and described base is fixed on universal testing machine.
Above-mentioned layer metal composite plate shearing test device, the cutting edge of described counterdie is processed into the fillet that radius is less than 0.1mm; Gap between gap between the vertical through-hole wall of the sidewall of drift and patrix, the sidewall of gland and the vertical through-hole wall of counterdie is not more than 0.1mm.
Above-mentioned layer metal composite plate shearing test device, the roughness Ra≤0.8 μ m of the inwall of the sidewall of described drift and gland and the vertical through hole of upper die and lower die.
The utility model will carry out the test of shearing strength after the basic unit of layer metal composite plate sample and the clamping simultaneously of multiple layer, not only can effectively avoid thin specification composite plate sample matrix when carrying out the pressure scissor test of GB/T6396-2008 regulation to occur bending and deformation under pressure, and avoided carry out GB/T6396-2008 regulation draw scissor test time thinner multiple layer be pulled off, greatly improved the success ratio of test and the measuring accuracy of layer metal composite plate shearing strength.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the assay maps that requires processing;
In figure, each label is: 1, drift; 2, gland; 3, patrix; 4, counterdie; 5, base; 6, clamping screw; 7, fastening bolt; 8, sample; 9, basic unit; 10, multiple layer.
Embodiment
Referring to Fig. 1, the utility model comprises drift 1, gland 2, patrix 3, counterdie 4, base 5, clamping screw 6 and fastening bolt 7.
Working method of the present utility model is as follows:
By the multiple layer segment of the sample preparing 8 being clamped between drift 1 and gland 2 shown in Fig. 1, during clamping, to note the justified margin of the compound interface of sample 8 and drift 1, gland 2, to just cut off at compound interface place while shearing.Use clamping screw 6 by drift 1 and gland 2 lockings, again gland 2 is put in the cutting edge of counterdie 4, with patrix 3, push down basic unit's part of sample 8, use fastening bolt 7 locking upper and lower moulds, twice locking is all in order to prevent that sample is subject to shearing force and does the used time and produce to tumble and affect measuring accuracy.Finally by bolt, counterdie 4 is fixed on base 5, base 5 is contained on universal testing machine, the pressure head of universal testing machine is slowly at the uniform velocity exerted pressure to drift 1, until sample cut off at compound interface place, finally with maximum pressure in the process of the test of universal testing machine record divided by the shearing strength of cutting off area and can obtain layered metal composite plate.
Drift 1, gland 2, patrix 3, the selected material of counterdie 4 are necessary for the material that hardness is larger, require edge hardness to be not less than 65HRC, can select W18Cr4V and the close steel grade of strength character after Quenching Treatment, remaining part material can be selected 45# steel and the close steel grade of performance.
The cutting edge of counterdie 4 should be processed into the fillet of radius R≤0.1mm.The inwall processing roughness of the outside surface of drift 1, gland 2 and patrix 3, counterdie 4 requires Ra≤0.8 μ m.In installation process, drift 1, gland 2, patrix 3, counterdie 4 require coaxially, and the gap between the cutting edge of drift 1, gland 2 and patrix 3, counterdie 4 is not more than 0.1mm.
When test layer metal composite plate shearing strength, should process two samples, symmetry folds up in the relative both sides of drift or processes four samples and folds up symmetrically on four limits at drift.
