Description
Technical field
Can be used for room temperature, the stretching of high temperature alloy sheet specimens the present invention relates to one kind, persistently with fixture, the fixture can be applied
Stretched under room temperature, high temperature, condition of high ground stress is carried out and enduring quality fixture for testing.
Background technology
The stretching of high temperature alloy sheet specimens and the test of croop property are a weights of performance under evaluation alloy working condition
Index is wanted, especially under aero-engine, gas turbine and hot-end component condition of work, alloy Leaf and structural member cross section
Pattern is laminated structure.Therefore the measure of the sheet specimens performance of alloy is important as evaluate alloy safety in utilization one
Index.
The content of the invention
Goal of the invention：
Regarding to the issue above, the present invention provides a kind of reusable hanging sheet specimens stretching, persistently uses fixture.This
Plant stretching, persistence that sheet specimens stretching clamp can be used under sheet specimens room temperature, the hot conditions that thickness is 0.5 ~ 3.0mm
Can measure, and the fixture can reuse.
Technical scheme：
A kind of hanging sheet specimens are stretched, persistently use fixture, including two parts of I-shaped chuck, U-shaped card, its feature
It is：The centre of I-shaped chuck head is provided with opening, and the I-shaped chuck head both sides position vertical with opening is provided with groove,
Make the section of opening both sides in I-shaped；I-shaped chuck afterbody is threaded；I-shaped chuck and U-shaped card are two,
The two ends of I-shaped sheet specimens are individually placed in two openings of I-shaped chuck, and are hung sheet specimens using U-shaped card
Between two I-shaped chucks, I-shaped chuck afterbody is connected on stretching or endurance testing machine.
I-shaped sheet specimens are fixed on I-shaped chuck by U-shaped card, the screw thread that I-shaped chuck passes through afterbody
It is connected on stretching or endurance testing machine.
Advantage and effect：
Using the sheet specimens fixture, sheet specimens can be stretched, the measure of enduring quality, and sheet specimens thickness
Most sheet performance test requirements can be met in the range of 0.5mm ~ 3.0mm.Compared with some wear latch structure sheet specimens fixture
With simple structure, sample is easily worked, and fixture is the characteristics of can repeatedly use.

Part, the component prepared is processed into required component using Conventional processing methods.
The present invention relates to a kind of hanging sheet specimens stretching, persistently use fixture, sample can be carried out room temperature, drawing by high temperature and
Enduring quality is tested, as shown in Figure 1, Figure 2, shown in Fig. 3 and Fig. 4, including 2 two parts of I-shaped chuck 1, U-shaped card, its feature
It is：The centre of the head of I-shaped chuck 1 is provided with opening 4, and the I-shaped chuck head both sides position vertical with opening is provided with recessed
Groove 5, makes the section of the both sides of opening 4 in I-shaped；I-shaped chuck afterbody is threaded；I-shaped chuck and U-shaped card are
Two, the two ends of I-shaped sheet specimens 3 are individually placed in two openings of I-shaped chuck, and use U- types clamp by I-shaped
Type sheet specimens are hung between two I-shaped chucks, and I-shaped chuck afterbody is connected on stretching or endurance testing machine, so that
Determine the mechanics and enduring quality of sample.
I-shaped sheet specimens 3 are fixed on I-shaped chuck 1 by U-shaped card 2, and I-shaped chuck 1 is by afterbody
It is threadedly connected on stretching or endurance testing machine.
When the present invention is used：
The present invention is a kind of reusable hanging sheet specimens stretching, persistently uses fixture, and its application method is：By band
Threaded I-shaped chuck 1 is fixed on stretching or endurance testing machine, and I-shaped sheet specimens 3 then are placed in into I-shaped folder
In opening 4 in the middle of first 1, then it is stuck on the groove 5 of I-shaped chuck 1 using U-shaped card 2, the two ends of I-shaped sample are adopted
It is fixed in the opening 4 of I-shaped chuck 1 with U-shaped card, so as to sample is fixed between two I-shaped chucks.Upper and lower two
After end is fixed respectively, the position between stretching, the upper lower chuck of lasting equipment adjustment is started.Can enter behind suitable position to be achieved
The test of row mechanics, enduring quality.If the chuck is prepared using high-temperature alloy material, can be used under hot conditions stretch and hold
The measure of long performance.
