Abstract
The utility model relates to a high-temperature impact non-standard test sample, wherein the two ends of the test sample are provided with a clamping blocks, connecting pins are arranged between the clamping blocks and the body of the test sample, the width of the clamping block is equal to the width t of the body of the test sample, the sum h of the height h2 of the clamping block and the height of the body of the test sample is 10 mm. The high-temperature impact non-standard test sample solves the problem that a high-temperature impact tester can not carry out the high-temperature impact tests for non-standard test samples, and the high-temperature impact tester can be widely applied after improving the test sample.
Description
Technical field
The utility model relates to the nonstandard sample of a kind of high temperature impact.
Technical background
Impulse test is a kind of dynamic mechanical test, be mainly used to measure the merit that sample consumed that thrusts definite shape, ballistic work can be used as a qualitative index judging material embrittlement trend, also can be used as an important means of check material and Technology for Heating Processing, ballistic work is to the quality of material, gross imperfection, and microstructure is very responsive, and this also to be static test can't disclose, so impulse test is widely used in the detection to metal material.Press GB/T229-2007 " the metal material summer is than pendulum impact test method ", standard sample is of a size of 10mm * 10mm * 55mm, shape is shown in Fig. 3,4, and in order to adapt to the diversity of present material, allow to use the nonstandard sample of 7.5mm * 10mm * 55mm, 5mm * 10mm * 55mm, 2.5mm * 10mm * 55mm, to satisfy impulse test to different materials.
In the elevated temperature impact test machine that uses at present, for guaranteeing that sample carries out impulse test under the temperature of regulation, the automatic sample conveying mode that adopts, behind i.e. heating in high temperature furnace, the insulation official hour, by the automatic sample conveying machine sample is got, finish feeding, impact process, whole process only 1～2 second, guaranteed the reliability of test temperature, but owing to high temperature furnace, sample conveying device have only been considered standard sample 10mm * 10mm * 55mm when designing, so this equipment can't carry out high temperature impact to nonstandard sample.
Summary of the invention
Technical problem underlying to be solved in the utility model can satisfy the confidential nonstandard sample of high temperature impact of asking, can carry out elevated temperature impact test of elevated temperature impact test for a kind of.
The utility model adopts following technical scheme:
The two ends of the utility model sample block are provided with fixture block, are provided with between fixture block and the sample block to be connected pin, and the width of fixture block is identical with the width t of sample block, the height h of fixture block
2Height h with the sample block
1Sum h is 10mm.
The length L of fixture block described in the utility model is 10mm-15mm, and optimum length L is 13mm.
The beneficial effects of the utility model: the utility model is on the basis that does not influence the test accuracy, nonstandard sample is transformed, two ends at the sample block are provided with fixture block, be provided with between fixture block and the sample block and be connected pin, the width of fixture block is identical with the width t of sample block, the height h sum of fixture block and sample block is 10mm, to adapt to the sample conveying device of elevated temperature impact test machine.The utility model mainly is to transform the sample two ends, makes its end surface shape reach 10mm * 10mm, and adapting to high temperature furnace and automatic sample conveying device, and middle impact site keeps the original sample structure, does not influence impact results.Adopt pin to be connected between sample and the fixture block, can bear high temperature and heat, stud end and flush or be lower than the surface.Nonstandard sample to 7.5mm * 10mm * 55mm, 5mm * 10mm * 55mm also can adopt this design philosophy to transform, thereby makes the specimen types of elevated temperature impact test more various, to adapt to the material of different-thickness.
The utility model solves the problem that the elevated temperature impact test machine can't carry out the elevated temperature impact test of nonstandard sample, and by transforming sample, it is more extensive that this type of high[elevated is used.The high temperature impact sample that the sample of this minimum designs for example.
Description of drawings
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is the utility model outside drawing;
Accompanying drawing 3 is the standard sample structural representation;
Accompanying drawing 4 is the A-A cut-open view of accompanying drawing 3.
In the accompanying drawings: 1 sample block, 2 fixture blocks, 3 connect pin.
Embodiment
Shown in accompanying drawing 1,2, the two ends of the utility model sample block 1 are provided with fixture block 2, are provided with between fixture block 2 and the sample block 1 to be connected pin 3, and the width of fixture block 2 is identical with the width t of sample block 1, the height h of fixture block 2
2Height h with sample block 1
1Sum h is 10mm.The length L of described fixture block 2 is 10mm-15mm, and optimum length L is 13mm.The utility model solves the problem that the elevated temperature impact test machine can't carry out the elevated temperature impact test of nonstandard sample, and it is more extensive that this type of high[elevated is used.The high temperature furnace and the sample conveying device of elevated temperature impact test machine all design according to standard sample, only be fit to 10mm * 10mm * 55mm sample shown in accompanying drawing 3,4, principle analysis from impulse test, impact testing machine mainly concentrates on the middle part of breach both sides to the impact site of sample, two ends mainly are supporting roles, therefore the structure at nonstandard sample two ends can be transformed to adapt to high temperature furnace and sample conveying device, shown in Fig. 1,2 the high temperature impact sample that the sample with 2.5mm * 10mm * this minimum of 55mm designs for example, i.e. h
1Be 2.5mm, t is 10mm, and the coupon body length is 55mm.The utility model is transformed the sample two ends, makes its end surface shape reach 10mm * 10mm, to adapt to high temperature furnace and automatic sample conveying device, i.e. h
1+ h
2=10mm.And middle impact site keeps the original sample structure, does not influence impact results.Adopt pin 3 to be connected between sample block 1 and the fixture block 2, can bear high temperature and heat, stud end and flush or be lower than the surface.Also can adopt at sample block 1 two ends the nonstandard sample of 7.5mm * 10mm * 55mm, 5mm * 10mm * 55mm fixture block 2 is set, thereby make the specimen types of elevated temperature impact test more various, to adapt to the material of different-thickness.
