Abstract
The utility model provides a metal material tensile test special-purpose clamp after radiation, which is composed of two U-shaped draw sleeves which adopt embedded connection, and have reversal installment directions, the same shapes and same structures, and two rectangle bodies with the same shapes and structures, wherein the U-shaped draw sleeves are connected with the draw rod of a tester via screws, each rectangle body is provided with a groove at the opening end on the side edge of the rectangle body, the groove has the shape and size adaptive to the sample ends for receiving the ends of a sample. The metal material tensile test special-purpose clamp after radiation resolves the problems such as that manipulators have difficult operation, and the after-radiation metal material tensile test can be completed by manipulators easily without demanding workers to enter into a reactor thermal chamber, and effectively reduce the radiation on workers.
Description
Technical field
The utility model relates to a kind of survey instrument of material mechanical performance, specifically is metal material stretching test unit clamp behind a kind of irradiation.
Background technology
Material also should possess the characteristics of anti-irradiation except that should having enough mechanical properties, anti-corrosion and heat resistance in the reactor.Material because the mechanical property that the neutron irradiation effect causes changes, is the important means that guarantees the reactor safety operation in the reactor operation process in the research reactor.Important indicator such as the strength of materials and plasticity is tested by tension test.Tensile test fixture then is an one of critical component of measuring the tensile mechanical properties of material.In process of the test, the two ends of sample should be fixed on the anchor clamps, and anchor clamps are fixedlyed connected with cupping machine, and testing machine is by the anchor clamps tensile sample, finally obtain the performance index such as tensile strength, yield strength, extensibility of sample.
The normal conditions lower clamp is a single integral body, and the upper end directly is fixed on the pull bar of testing machine, and sample is vertically hung chuck and got final product during test.But for the performance test of material behind the irradiation, testing equipment must be installed in the hot cell with function of shielding, carries out various operations with mechanical arm.If the employing plain clamp, because the limitation of Robot actions, particularly the small size sample installation difficulty is bigger for irradiated sample, operation inconvenience; Because anchor clamps are fixed on the pull bar of testing machine, when specimen shape changes, must enter the manual anchor clamps of changing in hot cell by operating personnel simultaneously, this will increase operation easier and staff's radioactive dose.
Summary of the invention
The purpose of this utility model is: metal material stretching test unit clamp behind a kind of irradiation is provided.This unit clamp can be used for the radioactivity place, with Robot actions, be easy to change, and the exposure dosage that can reduce a staff.
The utility model is achieved in that
The unit clamp of metal material stretching test behind a kind of irradiation, it is characterized in that: embedded mode connects described unit clamp by adopting, installation direction is opposite, and shape, two U types that structure is identical are helped pull a cart forms with shape, two square type main bodys that structure is identical; Internal thread is arranged at the top of helping pull a cart in described U type, and there is a U type breach centre, the below opening of helping pull a cart; Be connected with cylindrical section below the termination, top of square type main body, have groove below the cylindrical section, groove is positioned at the openend on the square type main body side, also has step section, segmental arc and round exit successively below the groove; The shape and the size of U type breach and termination adapt, in the U type breach that the termination embedding U type of square type main body is helped pull a cart.
Effect of the present utility model is: compare with plain clamp, because the utility model sample, anchor clamps are connected by simple embedded mode with the testing machine pull bar, chuck is changed convenient, solved the problem of Robot actions difficulty, can easily finish metal material stretching test behind the irradiation by mechanical arm, need not the staff enter the hot cell, effectively reduce staff's radioactive dose.

Mark among the figure: 1 is tensile sample, and 2 help pull a cart for the U type, and 3 is square type main body, and 4 is internal thread, and 5 is U type breach, 6 are the opening of helping pull a cart, and 7 is square type main body termination, and 8 is cylindrical section, and 9 is groove, and 10 is the step section, 11 is segmental arc, and 12 are outlet, and 13 is the sample termination, and 14 is transition section, and 15 is straight-line segment.
Embodiment
As shown in Figure 1 to Figure 3, embedded mode connects anchor clamps of the present invention by adopting, installation direction is opposite, and shape, two U types that structure is identical are helped pull a cart and 2 formed with shape, two square type main bodys 3 that structure is identical.On help pull a cart 2 top of U type one internal thread 4 that is connected with the testing machine pull rod screw is arranged, there is a U type breach 5 centre, the below opening 6 of helping pull a cart; Square type main body 3 can be designed to the difformity that adapts with sample, on the top of square type main body 3 termination 7 and cylindrical section 8 are arranged, the centre has from upper surface extends and opening groove 9 up to lower surface, groove 9 is positioned at the openend on the square type main body side, and the below has step section 10, segmental arc 11 successively and exports 12.
With a kind of circular shoulder type tensile sample 1 is that example describes, and the shape of this sample as shown in Figure 4.The termination 13 of sample 1 enters from groove 9 opening parts, the step section 10 of transition section 14 and square type main body 3 and segmental arc 11 pastes and, the straight-line segment 15 of sample 1 extends out from round exit 12 and enters in the groove 9 of another one square type main body 3, button-head 7 is entered from U type breach 5, and cylindrical section 8 extends out under shed 6.Adjust up and down help pull a cart distance between 2 of two U types, the termination circular 7 of another square type main body 3 is embedded in the U type breach 5 of below.
When sample 1 alteration of form need be changed anchor clamps, the U type was helped pull a cart and 2 need not be changed, and only needed current square type main body 3 is taken off, and the square type main body 3 that changes another groove shapes into gets final product.
