Description
Technical field
The present invention relates to a kind of thin plate tension test mould, specifically, is a kind of clamping die of high-temperature tensile test of thin plate, belongs to test mould technical field.
Background technology
Tension test refers to the test method of measuring material behavior under axial tension load bearing.Utilize the data that tension test obtains can determine the performance index such as elastic limit of materials, length growth rate, elastic modulus, proportional limit, area reduction, pulling strengrth, yield point, yield strength.The tension test of carrying out from high temperature can obtain creep data.
Existing thin plate tension test, the general general extension pin form of recommending in GB/T4338-2006 < < Metal Materials At High Temperature stretching test method > > that adopts has connected experiment, but along with investigation of materials obtains the development of advancing by leaps and bounds, at aerospace field, high-temp and high-strength thin plate is widely used in composite structure to improve the strength-weight ratio of parts, existing clamp structure is difficult to intensity and hardness high metal material like this to clamp, the phenomenon that may occur conquassation unstability.Therefore, provide a kind of suitable high temperature tension test fixture just to have eager demand.
Summary of the invention
The technical issues that need to address of the present invention are: high strength thin plate has the character of high rigidity, at high temperature performance is more obvious, be difficult to be threaded and sell hanging lock type and be connected experiment with general, fixture has been limited again in general hot environment equipment size space can not large scale.
The present invention takes following technical scheme:
A kind of high-temperature tensile test of thin plate fixture, the a pair of clamp body 2 that comprises mirror image symmetry, in described clamp body 2, be provided with wedge-shaped slot, in described wedge-shaped slot, be provided with a pair of pincers piece 3, the snug engagement of described pincers piece 3 and described wedge-shaped slot, the centre of a pair of pincers piece 3 is that thin plate is clamped, and described a pair of pincers piece 3 keeps sustained height by latch 4; Described pincers piece 3 bottoms are provided with a pair of arc shoulder 6, corresponding with the arcwall face of thin plate to be stretched; The center of described clamp body 2 is connected with pull bar.
When thin plate sample to be tested is clamped, first pincers piece 3 is taken out in clamp body 2, style two ends are clamped respectively with two teams' jaw, latch 4 is inserted in a pair of pincers piece 3, the wedge type notch of the clamp body 2 being connected with testing machine will be put into upper-part integral body, prestretched to the bilateral arc shoulder of sample and the arc shoulder 6 of jaw contacts, and completes clamping process, can continue tension test.The arc shoulder of jaw bilateral forms the holding force in sample front is born to test pulling force jointly the support reaction of sample and clamp body wedge type notch inclined-plane.
Further, described pull bar is ball-head tension rod 1.
Further, described clamp body outside is provided with housing 5.
Further, described pincers piece 3 is sphenoid structure.
Beneficial effect of the present invention is as follows:
1, holding force is stable, reliable, and without making the hardness of fixture and intensity far above sample.
2, the thin plate that adapts to high strength, high rigidity.
3, volume is little, simple in structure, and conserve space is suitable for hot environment equipment.
4, wedge surface forms the support reaction of the holding force in sample front and both shoulders formation is put on to sample jointly, and has avoided sample side both shoulders pressurized unstability.
Accompanying drawing explanation
Fig. 1 is the cross-sectional schematic that high-temperature tensile test of thin plate fixture clamps style.
Fig. 2 is the side view of Fig. 1 the first half structure.
In figure, 1. ball-head tension rod, 2. clamp body, 3. pincers piece, 4. latch, 5. housing.
Embodiment
Below in conjunction with specific embodiments and the drawings, the present invention is further described.
Referring to Fig. 1,2, a kind of high-temperature tensile test of thin plate fixture, the a pair of clamp body 2 that comprises mirror image symmetry, in described clamp body 2, be provided with wedge-shaped slot, in described wedge-shaped slot, be provided with a pair of pincers piece 3, the snug engagement of described pincers piece 3 and described wedge-shaped slot, the centre of a pair of pincers piece 3 clamps thin plate, and described a pair of pincers piece 3 keeps sustained heights by latch 4; Described pincers piece 3 bottoms are provided with a pair of arc shoulder 6, corresponding with the arcwall face of thin plate to be stretched; The center of described clamp body 2 is connected with pull bar.
Described pull bar is ball-head tension rod 1, and dirigibility is better, guarantees that up-down stretch axis is by the sample centre of form.
Described clamp body outside is provided with housing 5, and housing 5 is for increasing the intensity of clamp body 2.
Described pincers piece 3 is sphenoid structure.
When thin plate sample to be tested is clamped, now pincers piece 3 is taken out in clamp body 2, style two ends are clamped respectively with two teams' jaw, latch 4 is inserted in a pair of pincers piece 3, the wedge type notch of the clamp body 2 being connected with testing machine will be put into upper-part integral body, prestretched to the bilateral arc shoulder of sample and the arc shoulder 6 of jaw contacts, and completes clamping process, can continue tension test.The arc shoulder of jaw bilateral bears test pulling force to the support reaction of sample and clamp body wedge type notch inclined-plane jointly to the holding force in sample front.
The wedge type notch inclined plane force increasing clamping of clamp body 2 and jaw arc shoulder hanging structure are the core places of this fixture.
Jaw is that the protruding arc being connected as a single entity with pincers piece 3 is hung shoulder in a following side, has same v notch v in test.In the time of face-to-face, arc is hung shoulder and breach interlock, and clamping in theory sample thickness can be infinitely thin.
Referring to 1,2, latch 4 is for the extension shoulder position maintenance of pincers piece in pairs.
Referring to Fig. 2, the inclined plane force increasing of the wedge type notch of clamp body 2 clamping sample.
Referring to Fig. 1,2, ball-head tension rod 1 warranty test power is by the centre of form axis of sample.
Referring to Fig. 1, housing 5 is for increasing the intensity of clamp body.
The invention provides a kind of high-temperature tensile test of thin plate fixture, it is mainly used in the high temperature tension test of various high strength thin plates, and it is even less that sheet gauge can reach 0.1mm.This stretching clamp provides that a kind of experimental accuracy is high, clamping is reliable, reduced the requirement of test to equipment, to fill up existing technological gap, meet the requirement of GB/T4338-2006 < < Metal Materials At High Temperature stretching test method > > to fixture.
