Description

Homogeneous tube drawing by high temperature anchor clamps
Technical field
The utility model relates to the mechanical field stretching clamp, relates in particular to be used for metal small dimension pipe woods homogeneous tube section sample drawing by high temperature anchor clamps.
Background technology
Can adopt arc longitudinal strip sample high temperature tension test to big specification tubing, small dimension tubing can only adopt homogeneous tube section sample to carry out high temperature tension test.Homogeneous tube section sample drawing by high temperature adopts the outer method of clamping of stove usually, and sample must pass high-temperature heater, therefore needs clamping length reasonable in design, and the length of sample is very long, and general specimen length is about 600mm.Sample is oversize, and the depth of parallelism of sample and right alignment are difficult to be guaranteed, and measure yield strength with classical displacement, and error is very big, even if adopt expensive, advanced high-temperature electronic extensometer also to be difficult to carrying out smoothly of warranty test.Adopting the interior method of clamping of stove to carry out very difficulty of homogeneous tube section sample drawing by high temperature, mainly is the restriction that receives temperature, tubular high temperature stove size of burner hearth etc., and electrical technology can't find application.
The utility model content
To above-mentioned situation, the utility model provides the in-draw of a kind of employing homogeneous tube section sample high temperature furnace, measures the stretching clamp of the yield strength of tubing homogeneous tube section sample, i.e. telescopic wedge shape homogeneous tube drawing by high temperature anchor clamps of method of clamping in the stove are to address the above problem.
The utility model homogeneous tube drawing by high temperature anchor clamps comprise sleeve 1, compress tie rod 2, the fixture block 3 that presss from both sides mouth are arranged.
Said sleeve 1 connects taper shape for cylinder; It is identical with the cylindrical inner diameter diameter of sleeve 1 to compress tie rod 2 center section cylinder diameters; The cylinder shape inner wall of sleeve 1 has internal thread, and compressing tie rod 2 center section peripheries has external thread, and both closely contact.
There are two parallel surfaces 5 the said tie rod side, top that compresses tie rod 2.
Said sleeve 1 cylindrical outer wall has two parallel surfaces.
The lower end compressing end that compresses tie rod 2 adopts hollow tubular structure.
Said fixture block 3 is for pressing from both sides two of mouthful semicircle cones that is V-type or flat pattern.
The clamping face of fixture block 3 folder mouths adopts groove shape or odontoid.
Said compressing between tie rod 2 and the fixture block 3 has cushion block.
Its principle of work is: when carrying out high temperature tension test, the V-type of homogeneous tube section sample 8 ends being put into fixture block 3 is pressed from both sides mouth 6, and two ends add chock plug 7.Or, put into the sample end in the folder mouth 6 of flat pattern fixture block 3 with its both ends flattening.Rotate by hand then and compress tie rod 2 tops, the i.e. screw thread propelling in the cylinder shape inner wall internal thread of sleeve 1 of the external thread of intermediate portion periphery.Also can rotatably compress two parallel surfaces 5 of tie rod side, tie rod 2 top with small wrench, carry out screw thread and advance.The lower end compressing end that compresses tie rod 2 adopts hollow tubular structure, when compressing tie rod and compress fixture block, compresses tie rod and does not reach sample, can let sample have enough length to be held like this.After sample is stressed, drives fixture block and move down (principle is identical with Wedge gripping) along the angle of taper of conical sleeve, it is big more that fixture block moves down holding force more, thereby grasp homogeneous tube section sample.
When outwarding winding, available hand direct control, during too tight bad outwarding winding, two parallel planes of available spanner turnbarrel outer wall, and compress two parallel surfaces 5 of tie rod side, tie rod 2 top, can easily outward winding.
The topmost that compresses tie rod 2 is connected with the pull bar of testing machine.
The utility model is used for the drawing by high temperature test of external diameter at the following homogeneous tube section sample of 10mm (can expand according to high-temperature heater burner hearth situation).It adopts method of clamping in the stove, and volume is little, and is easy to operate, and specimen length only needs 150mm, with traditional displacement curve or deformation curve, all can make things convenient for the yield strength of accurate mensuration tubing homogeneous tube section sample.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
Fig. 1 is the whole diagrammatic cross-sections of the utility model homogeneous tube drawing by high temperature anchor clamps.
Fig. 2 is the tie rod that compresses of the utility model homogeneous tube drawing by high temperature anchor clamps.
Fig. 3 is the V-type fixture block or the flat pattern fixture block of the utility model homogeneous tube drawing by high temperature anchor clamps.
