Technical field
The utility model relates to tubing the field of test technology, more specifically, are related to a kind of for the examination of tubing room temperature tensile
The chock plug tested.
Background technique
When testing mechanical properties of tubular goods, according to " the metal material stretching test part 1: room temperature of national standard GB/T 228.1
Test method " it points out in annex E, allow to flatten after pipeline section sample two clamps head and be tested, but in actual test process
In, in the end of pressing, easily there is a situation where sample fractures, cause test data inaccurate；It also indicates that in annex E in sample
Both ends are jumped a queue head, and during the test usually plus pole chock plug, the shortcomings that the method is: various sizes of tubing needs to find
The chock plug of corresponding size, easy to fall off when cast sample due to being mounted on for pole chock plug, after test, chock plug needs auxiliary
Tool applies external force and releases, once chucking power is excessive, taking out chock plug will be very painstaking, and the method is time-consuming and laborious.
Application No. is a kind of 201520610136.4, utility models of entitled " chock plug for drawing pipe test "
Patent solves the problems, such as to flatten at tubing both ends, but the chock plug and round bar shape chock plug exist in disassembly process
Problem, it is still desirable to external force releases chock plug, once constriction is serious during stretching for tubing, chock plug is easy to not take not come out,
And spring is easily deformed after use, is unfavorable for repeatedly installing and using.
Utility model content
In view of the above problems, the purpose of the utility model is to provide a kind of chock plug for tubing tensile test at room temperature, with
Solve the problems, such as that chock plug is not easy to take out from tubing.
Chock plug provided by the utility model for tubing tensile test at room temperature, comprising: the first wedge block and shape size
Identical second wedge block, third wedge block；Wherein, the axial length of the first wedge block is longer than the second wedge block and third wedge shape
The axial length of block；The outer surface of second wedge block and third wedge block is respectively cambered surface, the second wedge block and third wedge block
Inner surface be respectively plane, the microcephaly of the second wedge block and the microcephaly of third wedge block are machined with the shaft shoulder respectively；First wedge shape
The outer surface of block is cambered surface, and two inner surfaces of the first wedge block are respectively the inner surface with the second wedge block, third wedge block
The plane to match, the major part of the first wedge block are threaded with the internal thread hole for installing bolt pull ring；And second wedge block
It being symmetrical arranged with third wedge block, the first wedge block is clipped between the second wedge block and third wedge block, and the first wedge block
Major part and microcephaly are all exposed the second wedge block and third wedge block, two inner surfaces of the first wedge block respectively with the second wedge block
It is bonded with the inner surface of third wedge block.
Using the chock plug for tubing tensile test at room temperature of above-mentioned the utility model, following technical effect can be obtained:
(1) structure is simple, is easily installed；
(2) reusable；
(3) the first wedge block is extracted by bolt pull ring, can quickly removes chock plug；
(4) test efficiency is improved；
(5) ensure the accuracy of test result.
Detailed description of the invention
