Technical field
The utility model relates to tensile sample and to have no progeny measurement servicing unit, refers to that a kind of metal stretching sample is had no progeny test desk particularly.
Background technology
Tension test is the most basic test of experimental material mechanical property, and wherein reduction of area Z is one of most important index of reflection material plasticity.Its expression formula is:
Z = S 0 - S u S 0 × 100 % - - - ( 1 )
In formula: S 0-original cross-sectional area (mm 2)
S u-have no progeny smallest cross-section area (mm 2)
Current S umeasurement be substantially all by manually completing, the sample broken is pieced together again, then measures the diameter that its constriction position is minimum, thus obtain the smallest cross-section area S that has no progeny u.To S in GB/T228-2002 uthe mensuration measured has done following regulation: during measurement, as needs, sample fracture part carefully connected together, its axis is on same straight line.For circular cross section sample, measure diameter in constriction minimum place mutually perpendicular direction, get its arithmetic mean and calculate smallest cross-section area; As Fig. 1, for rectangular cross section sample, measure the breadth extreme b at constriction place uwith minimum thickness a u, both products are the smallest cross-section area S that has no progeny u.
The smallest cross-section area S had no progeny umeasurement need the sample broken again to piece together and measure the minimum cross-sectional area of its constriction, so just there is following problem: 1, bar samples is had no progeny and measure the problem that vertical direction is got in cross section, namely after section gauge crosses a diameter, need by sample vertically half-twist measure again once in same position.First twice direction of measurement cannot ensure vertically, and ensures that vertical survey is standard regulation, is also that measuring accuracy is very necessary, especially some fractures is presented to the sample of obvious oval feature; 2, for plate tensile sample thickness direction a utest very inconvenient, as shown in Figure 1, plate tensile sample fracture presents the thick shape in intermediate thin both sides, very inconvenient to plate tensile sample thickness measure of having no progeny with milscale, is that the sample broken just difficult for more still more.
Summary of the invention
The purpose of this utility model to provide exactly a kind of structure simple, operate tensile sample easily and to have no progeny test desk, fast can measure metal by this test desk to have no progeny tensile sample end face shrinkage factor Z, precision and the efficiency of test can be improved, and it is safe and reliable, cheap for manufacturing cost, there is good adaptability and practical value.
For achieving the above object, tensile sample designed by the utility model is had no progeny test desk, comprise formal parameter identical, and matching used free end magnetic bases and stiff end magnetic bases, bottom surface and the side of described free end magnetic bases and stiff end magnetic bases are perpendicular, the end face of described free end magnetic bases and stiff end magnetic bases is respectively arranged with the free end sink deck and stiff end sink deck that are suitable for placing plate type tensile specimen measurement, the middle part of described free end sink deck and stiff end sink deck is respectively arranged with the free end V-type groove and stiff end V-type groove that are suitable for placing the measurement of bar-shaped tensile sample.
Also correspondingly on described free end magnetic bases and stiff end magnetic bases be provided with through hole and mounting hole, one end secure fit of described mounting hole and sliding bar, the other end and the described through hole of described sliding bar are slidably matched, thus free end magnetic bases can be moved, to adapt to the needs that different length tensile sample is measured relative to stiff end magnetic bases along sliding bar.
Principle of work of the present utility model is such: the tensile sample broken in two is placed on free end magnetic bases respectively, on stiff end magnetic bases, magnetic bases hold sample by magnetic force, regulate the tensile sample position broken in two respectively, it is made again to piece together, carry out first time by the size of vernier caliper to the good minimum place of tensile sample constriction of split to measure, tensile sample have no progeny test desk half-twist place, carry out second time by the size of vernier caliper to the minimum place of tensile sample constriction of having no progeny to measure, the smallest cross-section area of tensile sample of having no progeny then is calculated by measured value, and then calculate the reduction of area Z of tensile sample of having no progeny.
Preferably, the side of described free end magnetic bases is also provided with the threaded hole communicated with through hole, be provided with in described threaded hole can screw in abut with sliding bar coordinate hold out against screw.Like this, behind the position according to the length adjustment free end magnetic bases of tensile sample of having no progeny, free end magnetic bases can simple and direct, be securely fixed on sliding bar.
Further, described threaded hole is provided with two; Correspondingly, hold out against screw described in and be also provided with two.Like this, free end magnetic bases and sliding bar can not relatively rotate, and connect more fastening, measure more accurate.
Advantage of the present utility model is mainly reflected in following several respects:
One, by the setting of magnetic bases, goes for the tensile sample of having no progeny of difformity, different length specification.
Its two, by tensile sample have no progeny test desk half-twist place carry out second time measure, solve bar samples have no progeny diameter of section measurement Perpendicular Problems, improve the precision of test.
Its three, this device can complete the measurement of reduction of area Z and extensibility A simultaneously, and can improve precision and the efficiency of test, device is easy to use, safe and reliable, cheap for manufacturing cost, has good adaptability and practical value.
