Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet-like, film-like or plate-like material test piece continuum in a material test.

[0002]

2. Description of the Related Art When conducting a material test on a sheet, film or plate sample, the test piece to be tested is a sheet or film sample. Each piece was stamped and formed separately, and a plurality of pieces of a plate were prepared independently from one sample using a cutting cutter or the like. This test piece is shown in FIGS. This known test piece is configured as an independent small piece, has grip portions 1 and 1 at both ends, and has a narrowed portion 2 or a concave portion 3 formed in the middle.

[0003]

The above-mentioned conventional test pieces composed of individual small pieces have the following problems. Discrimination between different samples, the order in which tests are performed, and the arrangement and alignment of test pieces are complicated. Since a test piece made from a sheet-like or film-like sample is difficult to stand on its own, mounting on a gripping tool becomes complicated. If the test piece is small, it becomes more complicated. In addition, there is a problem that if the material testing apparatus is to be automated, it is disadvantageous mechanically in the following points. Specimens that are not easily self-supporting are difficult to handle by gripping and are often suctioned.However, suction is less reliable than gripping and causes failures such as dropping of test specimens from the conveyor during automation. Becomes When automating from the stage of preparing a test piece from a sheet or film sample, a mechanism for collecting the test piece created by a punch cutter or the like, and positioning and aligning it at a predetermined position is necessary,
The device becomes complicated. In the case of automating from the stage of preparing a test piece from a plate-shaped sample, a mechanism for collecting a test piece prepared by a cutter or the like and positioning and aligning the test piece at a predetermined position is required, and the apparatus becomes complicated.

[0004] In view of the above-mentioned problems of the conventionally known material test pieces, the present invention not only facilitates the handling of the test pieces themselves, that is, the arrangement and alignment of the test pieces, but also is extremely effective in automating the material test apparatus. The object of the present invention is to provide a material test piece continuum that is:

[0005]

Means for Solving the Problems For this purpose, in the present invention,
Is formed with a plurality of vent holes are aligned so that a plurality of single-shaped test pieces are each arranged in, four peripheries frame sheet formed integrally by unit, and the film-like or plate-like rectangular shape, as it is To supply the material testing equipment
A material test piece continuum is provided.

[0006]

Since the continuous material test piece of the present invention has a rectangular shape in which a plurality of test pieces are continuously integrated as described above, it is larger than a conventional single test piece itself. It is easy to handle and manage such arrangement and arrangement. Also,
In automating the material testing apparatus, since it is rectangular and relatively large, it is easy to automate the supply or gripping.

[0007]

FIG. 1 shows a preferred embodiment of the material test piece continuum of the present invention. This material test piece continuum 10
Is formed in a square sheet, film or plate shape, and similarly to the known test piece shown in FIG. 4, a grip 11 and a narrowed portion 12 located between the grips 11 are formed in the square sheet. A plurality of punched holes 15 are formed side by side so that a plurality of test pieces to be formed are formed side by side, and are integrated by the four peripheral frame portions 14 of the sheet.

FIG. 2 shows another preferred embodiment,
Parts indicated by the same reference numerals as those in FIG. 1 are the same parts.
In this embodiment, a configuration in which the gripping portion 11 of the test piece and the four peripheral portions 14 are used is shown, which is preferable in that the material can be saved.

FIG. 3 shows a continuum of the known test piece shown in FIG. 5 according to the present invention. In FIG. 3, the same reference numerals as those shown in FIG. 1 denote the same parts. The difference from the first embodiment is that a concavity 13B corresponding to the concavity 3 shown in FIG.

[0010] When a material test is performed using the material test piece continuous body of the present invention configured as described above, the material test apparatus grips the test piece continuous body, and the material test apparatus grips the test piece continuous body. The gripping part 11 of the test piece on one side of the body is gripped, and a material test is performed by cutting between the four circumferential frames and the adjacent test piece. When the test is completed, the next test piece is gripped. The part 11 is moved so as to be gripped by the gripping part of the apparatus, and cuts between adjacent test pieces in the gripped state, and the test is performed in the same manner.

[0011]

[Effect of the Invention] As described above, the material test piece continuum of the present invention has a rectangular shape and is relatively large, so that the handling of the material test piece is easy and the handling such as supply to the material testing apparatus is also easy. It has a practical effect.
