Description
Technical field
The present invention relates to field of machining, more particularly to a kind of processing method of tensile sample.
Background technology
Tension test is to determine the experiment of series of characteristics of the material under tensile load effect, also known as tensile test.It
It is one of basic skills of mechanical property of materials experiment, is mainly used in whether experimental material meets defined standard and research material
Performance.
Need to fix sample to be checked using stretching clamp in tension test, stretching clamp is big by the size and test force of sample
It is small to determine.When sample is cylindrical type, sample need to be fixed using the fixture of bilateral structure, therefore, it is necessary to the two of sample
End processing screw thread, prevents sample from being skidded during tension test, the accuracy of guarantee test process and result.
To make sample meet tension test specification requirement, first have to sample to be processed to cut into the rectangle of certain size
Blank block, then stud shape is processed at the both ends of sample, the thread size at both ends and the screw thread of stretching tool is coordinated unanimously.But
It is after the screw thread for processing sample one end, it is then more difficult that screw thread process is carried out to the other end.If pressed from both sides with three claw clips of lathe
The one end tightly processed processes the other end, then can damage manufactured screw thread, causes the sample after processing and tension test
Size of sample require to produce relatively large deviation, influence the crudy of sample, it is difficult embedded testing machine to cause the sample after processing
Stretching tool, or even can not be embedded in, influence to carry out tensile property analysis to material to be detected.
The information for being disclosed in the background section is merely intended to understanding of the increase to the general background of the present invention, without answering
It has been the prior art well known to persons skilled in the art when being considered as recognizing or implying the information structure in any form.
The content of the invention
It is an object of the invention to provide a kind of processing method of tensile sample, so as to overcome existing sample processing method
It is easily damaged the defects of screw thread at both ends causes the result of the test of tensile property.
To achieve the above object, the invention provides a kind of processing method of tensile sample, tensile sample is cylindric, and
The both ends of tensile sample are equipped with external screw thread, and processing method comprises the following steps：With the blank of gripping means grips tensile sample,
And blank is processed into columned tensile sample；With the first end of gripping means grips tensile sample, the of tensile sample
Two ends process one section of external screw thread；With the middle part of gripping means grips tensile sample, one is processed in the first end of tensile sample
Section external screw thread；The swivel nut that the external screw thread of processing and tensile sample matches, the swivel nut of identical two and half is separated into by swivel nut；By one
Half swivel nut is arranged on the first end of tensile sample or the external screw thread at the second end；With gripping means grips swivel nut, middle part is processed
Into predetermined shape.
Preferably, in above-mentioned technical proposal, clamping device is three claw clips.
Compared with prior art, the present invention has the advantages that：
The processing method of the present invention is without effective on the basis of to the clamping device of process equipment significantly change
The texture of manufactured screw thread is protected, makes its without damage, ensures that the tensile sample after processing meets tensile test piece
Specification standards, it is ensured that the accuracy of tension test.

Embodiment
Below in conjunction with the accompanying drawings, the embodiment of the present invention is described in detail, it is to be understood that the guarantor of the present invention
Shield scope is not limited by embodiment.
Explicitly indicated that unless otherwise other, otherwise in entire disclosure and claims, term " comprising " or its change
Change such as "comprising" or " including " etc. and will be understood to comprise stated element or part, and do not exclude other members
Part or other parts.
As shown in figure 1, comprised the following steps according to the processing method of the tensile sample of the specific embodiment of the invention：
Sample to be processed is cut into the rectangle blank of certain size.
Blank is clamped with three claw clips 5 of process equipment, and blank is processed into columned tensile sample 1, such as Fig. 2 institutes
Show.
With the first end of the garter extension sample 1 of three claw clip 5 of process equipment, one is processed at the second end of tensile sample 1
Section external screw thread 2, as shown in Figure 3.The diameter of external screw thread 2 is smaller 1-3mm than the diameter of above-mentioned cylinder.
With the parallel-segment 4 (as shown in Figure 6) at the middle part of the garter extension sample 1 of three claw clip 5 of process equipment, in tensile sample
