Description
The present invention relates to a plastic strain ratio measuring device, and more particularly to a plastic strain ratio measuring device for measuring the plastic strain ratio of the specimen during the tensile test.
Tensile test is the most basic test among industrial tests conducted for the purpose of obtaining basic data on material strength. It is an important test method for evaluating the elasticity and plasticity of the mechanical properties of materials. The advantage of the tensile test is that the distribution of stress on the specimen is well interpreted, the test method is easy, and the test can be carried out economically. In this tensile test, the plastic strain ratio (r = w / 1) can be measured using the strain value (w) in the width direction when the specimen reaches the tensile elongation specified by the tensile tester. Deformation w in the width direction of the specimen is measured by the tester's manual operation.

In addition, the support member is preferably rounded to be in linear contact with the specimen.
The measuring unit may further include: a second connecting unit installed at the installation unit; An accommodation unit coupled to the second connection unit; And a measuring sensor unit installed in the receiving unit and in contact with the specimen to measure the width of the specimen.
In addition, it is preferable that the inside of the accommodation portion is formed to penetrate through, and the measurement sensor unit is movably coupled to the interior of the accommodation portion.
In addition, the installation portion, the main body portion to form an appearance; A first interval adjusting unit movably coupling the support unit to the main body unit; And a second interval adjusting unit for movably coupling the measurement unit to the main body unit.
In addition, the installation unit preferably further includes a pressing unit for pressing the first interval control unit and the second interval control unit in a direction close to each other.
According to the plastic strain ratio measuring apparatus of the present invention, the contact between the measuring sensor unit and the specimen is in close contact with the specimen to suppress the change in the measurement position while automatically measuring the plastic strain ratio of the specimen, thereby making manual work of the tester Compared to the measurement method through the plastic strain ratio can be measured easily and accurately.
In addition, the present invention is formed in a small size similar to the size of the specimen to be measured and can be manufactured with a light weight, so that the manufacturing cost is low, easy to store and transport, and can improve the convenience of measurement. .
In addition, the present invention has a structure in which each component, such as a support, a measuring unit, and an installation unit, is detachably coupled, so that not only is easy to store and transport, but also easy to repair and replace each component.
